GETTING TO KNOW YOUR VEHICLE

KEYS

KEY FOB

Your vehicle is equipped with a key fob that supports Passive Entry, Remote Keyless Entry (RKE), Keyless Enter ‘n Go™ (if equipped), Remote Start (if equipped), and remote power liftgate (if equipped) operation. The key fob allows you to lock or unlock all doors and liftgate, as well as activate the Panic Alarm from distances up to approximately 66 ft (20 m). The key fob does not need to be pointed at the vehicle to activate the system. The key fob also contains an emergency key, which is stored in the rear of the key fob.

NOTE:

In vehicles equipped with Remote Start, the key fob will operate at distances up to 328 ft (100 m).

NOTE:

• The key fob’s wireless signal may be blocked if the key fob is located next to a mobile phone, laptop, or other electronic device. This may result in poor performance.
• If your vehicle is equipped with a Wireless Charging Pad, the key fob may not be detected if it is placed within 6 inches (15 cm) of the pad Ú page 72.
• With the ignition in the ON position and the vehicle moving at 2 mph (4 km/h), all RKE commands are disabled.

1. LED Indicator
2. Unlock
3. Lock
4. Remote Start
5. Power Liftgate
6. Panic
7. Emergency Key

In case the ignition switch does not change positions with the push of a button, the key fob may have a low or fully depleted battery. A low-key fob battery can be verified by referring to the instrument cluster, which will display directions to follow. For more information on ignition positions, see page 19.

NOTE:

A low-key fob battery condition may be indicated by a message in the instrument cluster display, or by the LED light on the key fob. If the LED key fob light no longer illuminates after a key fob button is pushed, then the key fob battery requires replacement Ú page 358.

To Lock/Unlock The Doors And Liftgate

Push and release the unlock button on the key fob once to unlock the driver’s door, or twice within five seconds to unlock all the doors and the liftgate. To lock all the doors and the liftgate, push the lock button once. If enabled within the Uconnect system, the turn signals will flash and other illuminated entry features will be activated when the doors are unlocked. When the doors are locked, the turn signals will flash and the horn will chirp.

NOTE:

• If the vehicle is equipped with the Auto Relock feature and is unlocked with the key fob, and no door is opened within 60 seconds, the vehicle will relock and the Vehicle Security system will arm (if equipped). This feature can be enabled/disabled within Uconnect Settings.
• If one or more doors are open, or the liftgate is open, the doors will lock. The doors will unlock again automatically if the key fob is left inside the passenger compartment, otherwise, the doors will stay locked.

All doors can be programmed to unlock on the first push of the unlock button through Uconnect Settings page 181.

Using The Panic Feature

To turn the Panic feature on or off, push the Panic button on the key fob. When the Panic feature is activated, the turn signals will flash, the horn may pulse on and off (if equipped with a horn alarm), and the interior lights will turn on. The Panic feature will stay on for three minutes unless you turn it off by either pushing the Panic button a second time or driving the vehicle at a speed of 15 mph (24 km/h) or greater.

NOTE:

• The interior lights will turn off if you place the ignition in the ON/RUN position while the Panic feature is activated. However, the exterior lights and horn (if equipped with a horn alarm) will remain on.
• You may need to be closer than 66 ft (20 m) from the vehicle when using the key fob to turn off the Panic feature due to the radio frequency noises emitted by the system.

Key Left Vehicle Feature

If a valid key fob is no longer detected inside the vehicle while the vehicle’s ignition system is in the ON/RUN or START position, the message “Key Fob Has Left The Vehicle” will be shown in the instrument cluster display along with an interior chime. An exterior audible and visual alert will also be activated to warn the driver.
The vehicle’s horn will rapidly chirp three times along with a single flash of the vehicle’s exterior lights.

NOTE:

• The doors have to be open and then closed in order for the vehicle to check for the presence of a key fob; the Key Left Vehicle feature will not activate until all of the doors are closed.
• These alerts will not be activated in situations where the vehicle’s engine is left running with the key fob inside.

Using The Key Fob To Open Vehicle Windows — If Equipped

From outside of the vehicle, push and release the unlock button on the key fob, and within five seconds push and hold the unlock button for up to seven seconds. All vehicle door windows will open.

NOTE:

• This feature is enabled through Uconnect Settings
  Ú page 181.
• The vehicle must be equipped with front and rear auto up/down windows.

Replacing The Battery In The Key Fob

The replacement battery model is one CR2450 battery.

NOTE:

• Customers are recommended to use a battery obtained from Mopar®. Aftermarket coin battery specifications may not meet the original OEM coin battery specifications.
• Perchlorate Material — special handling may apply. See www.dtsc.ca.gov/hazardouswaste/perchlorate for further information.
• Do not touch the battery terminals that are on the back housing or the printed circuit board.
• Do not replace the coin battery if the LED on the key fob above the top row buttons blinks when a button is pressed. The coin battery should last a minimum of three years with normal vehicle usage.

1. Remove the emergency key (2) by pushing the emergency key release button (1) on the side of the key fob, and pulling the emergency key out with the other hand.
2. Hold the key fob with the button side facing down, and locate the small rectangular gap on the left side between the housing and the back cover of the key fob. Use a small flat-bladed tool to pry apart the two halves of the key fob. Make sure not to damage the seal during removal.
3. Next, locate the gap on the right side of the key fob, which is positioned farther to the edge than the left side gap. Pry open the right side, and remove the back cover.
4. Remove the battery by using your thumb to slide the battery downward and back toward the key ring.

NOTE:

You can also insert a screwdriver or similar tool into the battery removal pocket to pry the battery out.

NOTE:

When replacing the battery, ensure the (+) sign on the battery is facing upward. Avoid touching the new battery with your fingers. Skin oils may cause battery deterioration. If you touch a battery, clean it with rubbing alcohol.

5. Replace the battery by using your thumb to push
6. To assemble the key fob case, line up the top edge of the back cover with the top of the fob, and press the edges into the interlocking hinges until all edges snap together with no large visual gaps.
7. Reinsert the emergency key until it locks into place.

NOTE:

The key fob battery should only be replaced by qualified technicians. If the battery requires replacement, see an authorized dealer.

WARNING!

• The integrated key fob contains a coin cell battery. Do not ingest the battery; there is a chemical burn hazard. If the coin cell battery is swallowed, it can cause severe internal burns in just two hours and can lead to death.
• If you think a battery may have been swallowed or placed inside any part of the body, seek immediate medical attention.
• Keep new and used batteries away from children. If the battery compartment does not close securely, stop using the product and keep it away from children.

Programming And Requesting Additional Key Fobs

Programming the key fob may be performed by an authorized dealer.

NOTE:

• Once a key fob is programmed into a vehicle, it cannot be repurposed and reprogrammed into another vehicle.
• Only key fobs that are programmed to the vehicle electronics can be used to start and operate the vehicle. Once a key fob is programmed to a vehicle, it cannot be programmed to any other vehicle.

WARNING!

• Always remove the key fobs from the vehicle and lock all doors when leaving the vehicle unattended.
• Always remember to place the Keyless Enter ‘n Go™ Ignition in the OFF position when exiting the vehicle.

Duplication of key fobs may be performed at an authorized dealer. This procedure consists of programming a blank key fob to the vehicle electronics. A blank key fob is one that has never been programmed.

NOTE:

• When having the Sentry Key Immobilizer system serviced, bring all vehicle keys with you to an authorized dealer.
• Keys must be ordered to the correct key cut to match the vehicle locks.

SENTRY KEY

The Sentry Key Immobilizer system prevents unauthorized vehicle operation by disabling the engine. The system does not need to be armed or activated. Operation is automatic, regardless of whether the vehicle is locked or unlocked. The system uses a key fob, keyless push-button ignition, and a Radio Frequency (RF) receiver to prevent unauthorized vehicle operation. Therefore, only key fobs that are programmed into the vehicle can be used to start and operate the vehicle. The system cannot reprogram a key fob obtained from another vehicle. After placing the ignition in the ON/RUN position, the Vehicle Security Light will turn on for three seconds for a bulb check. If the light remains on after the bulb check, it indicates that there is a problem with the electronics. In addition, if the light begins to flash after the bulb check, it indicates that someone attempted to start the engine with an invalid key fob. In the event that a valid key fob is used to start the engine but there is an issue with the vehicle electronics, the engine will start and shut off after two seconds. If the Vehicle Security Light turns on during normal vehicle operation (vehicle running for longer than 10 seconds), it indicates that there is a fault in the electronics. Should this occur, have the vehicle serviced as soon as possible by an authorized dealer.

CAUTION!

The Sentry Key Immobilizer system is not compatible with some aftermarket Remote Start systems. Use of these systems may result in vehicle starting problems and loss of security protection.

All of the key fobs provided with your new vehicle have been programmed to the vehicle electronics Ú page 358.

NOTE:

A key fob that has not been programmed is also considered an invalid key.

IGNITION SWITCH

KEYLESS ENTER ‘N GO™ IGNITION

This feature allows the driver to operate the ignition switch with the push of a button as long as the key fob is in the passenger compartment. The START/STOP ignition button has several operating modes that are labeled and will illuminate when in position. These modes are OFF, ON/RUN, and START.

START/STOP Ignition Button

1.  OFF
2. ON/RUN

The push-button ignition can be placed in the following modes:
OFF

• The engine is stopped
• Some electrical devices (e.g. power locks, alarms, etc.) are still available

ON/RUN

• Driving position
• All electrical devices are available (e.g. climate controls, heated seats, etc.)

START

• The engine will start (when the foot is on the brake pedal) NOTE:
• If the ignition position does not change with a push of the ignition button, and the instrument cluster displays a message such as “Key Fob Not Detected”, the key fob may have a low or depleted battery. In this situation, a backup method can be used to operate the ignition switch. Put the nose side of the key fob (the side opposite of the emergency key) against the START/STOP ignition button and push to operate the ignition switch.
• Replacement of the key fob battery is recommended.

Depleted Key Fob Battery Procedure

WARNING!

• When exiting the vehicle, always place the ignition in the OFF position, remove the key fob from the vehicle, and lock your vehicle.
• Never leave children alone in a vehicle, or with access to an unlocked vehicle.
•  Allowing children to be in a vehicle unattended is dangerous for a number of reasons. A child or others could be seriously or fatally injured. Children should be warned not to touch the parking brake, brake pedal, or gear selector.
• Do not leave the key fob in or near the vehicle, or in a location accessible to children, and do not leave Keyless Enter ‘n Go™ Ignition in the ON/RUN position. A child could operate power windows, and other controls, or move the vehicle.
• Do not leave children or animals inside parked vehicles in hot weather. Interior heat buildup may cause serious injury or death.

CAUTION!

An unlocked vehicle is an invitation for thieves. Always remove key fob from the vehicle and lock all doors when leaving the vehicle unattended.

NOTE:

• The key fob may not be detected by the vehicle Keyless Enter ‘n Go™ system if it is located next to a mobile phone, laptop, or other electronic device, or in the cupholders near aluminum cans; these devices may block the key fob wireless signal and prevent the Keyless Enter ‘n Go™ system from starting the vehicle.
• For more information on the engine starting procedure, see Ú page 109.
• When opening the driver’s door and the ignition is in the ON/RUN position (engine not running), a chime will sound to remind you to place the ignition in the OFF position. In addition to the chime, the message “Ignition ON” will display in the cluster.

REMOTE START — IF EQUIPPED

This system uses the key fob to start the engine conveniently from outside the vehicle while still maintaining security. The system has a range of approximately 328 ft (100 m). Remote Start is used to defrost windows in cold weather and to reach a comfortable climate in all ambient conditions before the driver enters the vehicle.

NOTE:

Obstructions between the vehicle and key fob may reduce this range Ú page 358.

WARNING!

• Do not start or run an engine in a closed garage or confined area. Exhaust gas contains carbon monoxide (CO) which is odorless and colorless. Carbon monoxide is poisonous and can cause serious injury or death when inhaled.
• Keep key fobs away from children. Operation of the Remote Start system, windows, door locks, or other controls could cause serious injury or death.

HOW TO USE REMOTE START

Push and release the Remote Start button on the key fob twice within five seconds. The vehicle doors will lock, the parking lights will flash, and the horn will chirp twice (if programmed). Then, the engine will start, and the vehicle will remain in the Remote Start mode for a 15-minute cycle. Pushing the Remote Start button a third time shuts the engine off.

NOTE:

• If the Remote Start button on the key fob is pushed too rapidly during activation, the vehicle may not start.
• With Remote Start, the engine will only run for 15 minutes.
• Remote Start can only be used twice.
• If an engine fault is present or the fuel level is low, the vehicle will start and then shut down in 10 seconds.
• The parking lights will turn on and remain on during Remote Start mode.
• Headlight animation (if equipped) will occur when Remote Start is activated, if “Headlight Illumination On Approach” is enabled within Uconnect Settings.
• For security, the power window and power sunroof operation (if equipped) are disabled when the vehicle is in the Remote Start mode.
• The ignition must be placed in the ON/RUN position before the Remote Start sequence can be repeated for a third cycle.

All of the following conditions must be met before the engine will remotely start:

• For vehicles equipped with the Keyless Enter ‘n Go™ — Passive Entry feature, the message “Remote Start Active — Push Start Button” will display in the instrument cluster display until you push the START/STOP ignition button.

REMOTE START FRONT DEFROST ACTIVATION — IF EQUIPPED

When Remote Start is active, and the outside ambient temperature is 40°F (4.5°C) or below, the system will automatically activate the front defrost for 15 minutes or less. The timing is dependent on the ambient temperature. Once the timer expires, the system will automatically adjust the settings depending on ambient conditions. See “Remote Start Comfort Systems — If Equipped” in the next section for detailed operation.

REMOTE START COMFORT SYSTEMS — IF EQUIPPED

When Remote Start is activated, the front and rear defrost will automatically turn on in cold weather. The heated steering wheel and driver heated seat feature will turn on if selected in the Comfort menu screen within Uconnect Settings Ú page 181. In warm weather, the driver-vented seat feature will automatically turn on when Remote Start is activated if programmed in the Comfort menu screen. The vehicle will adjust the climate control settings depending on the outside ambient temperature.

Automatic Temperature Control (ATC)

The climate controls will automatically adjust to the optimal temperature and mode settings depending on the outside ambient temperature. This will occur until the ignition is placed in the ON/RUN position where the climate controls will resume their previous settings. For more information on ATC and climate control settings, see Ú page 59.

NOTE:

These features will stay on through the duration of Remote Start until the ignition is placed in the ON/RUN position. The climate control setting will change, and exit automatic operation, if manually adjusted by the driver while the vehicle is in Remote Start mode. This includes the
OFF button on the climate controls, which will turn the system off.

REMOTE START WINDSHIELD WIPER DE-ICER ACTIVATION — IF EQUIPPED

When Remote Start is active and the outside ambient temperature is less than 33°F (0.6°C), the Windshield Wiper De-Icer will activate. Exiting Remote Start will resume its previous operation. If the Windshield Wiper De-Icer is active, the timer and operation will continue on page 181.
