Remote Engine Start System (Dealer Option)

WARNING

• There are some general precautions when starting the engine. 
• Do not remote start a vehicle in an enclosed environment (e.g. closed garage). The prolonged operation of a motor vehicle in an enclosed environment can cause a harmful build-up of carbon monoxide. Carbon monoxide is harmful to your health. Exposure to high levels of carbon monoxide can cause headaches, dizziness, or in extreme cases unconsciousness and/or death.

The remote engine start system allows you to start the engine from outside the vehicle. In addition, the remote engine start system can activate the heater or air conditioner, providing you with a comfortable cabin upon entry. For more details, refer to the Owner’s Manual Supplement for the remote engine start system.

NOTE

• The length of time for which it is acceptable to allow the engine to remain idling may be bound by local laws and regulations. Check the local rules when using the remote engine start system.
• When taking your vehicle in for service, it is recommended that you inform the service personnel that your vehicle is equipped with a remote engine start system.

Remote Engine Starter Transceiver (Fob)

Fob button

Starting the engine

NOTE
All vehicle doors (including the rear gate) and the engine hood must be closed prior to activating the remote engine start system. Any open entry point will prevent starting or cause the engine to stop. The remote engine start system is activated by pressing the fob button on your remote engine starter transceiver (fob) twice within 3 seconds. If the fob is within the operating range of the system and the start request is received, the following will occur.

• The fob flashes and beeps once.
• The horn sounds once.
  • The side marker lights, tail lights, and parking lights flash once.
  • If the fob is not within range (the user is too far away from the vehicle), the fob will indicate two long flashes without beeping.
  • The system will check certain safety preconditions before starting, and if all conditions are met, the engine will start within 5 seconds. After the engine starts, the following will occur.
  • The fob flashes and beeps twice.
• The horn sounds once.
• The side marker lights, tail lights, and parking lights flash once.
• While the engine is idling via the remote engine start system, the following will occur.
• The side marker lights, tail lights, and parking lights remain illuminated.
• The fob button flashes once every 3 seconds.
• The power windows are disabled. If the engine turns over but does not start (or starts and stalls) the remote engine start system will power off and then attempt to start the engine 3 additional times.
• The system will not attempt to restart the engine if it determines a vehicle malfunction is preventing starting. If the engine does not start after 3 additional attempts, the remote engine start request will be aborted.

Stopping the engine
Press and hold the fob button for at least 2 seconds to stop the engine. The fob will flash and beep three times, indicating the engine has stopped. If the stop request is not received (for example, if the user is too far away from the vehicle), the fob will continue to flash once every 3 seconds. The system will automatically stop the engine after 15 minutes.

Remote start safety features
For safety and security reasons, the remote engine start system will prevent starting (or stop the engine if running) and sound the horn twice if any of the following conditions is detected. In addition, the fob will flash and beep 3 times.

• The brake pedal is depressed.
• A key is in the ignition switch.
• The engine hood is open.
• The engine idle speed exceeds 3,500 rpm.
• The security alarm is triggered.
• The select lever is not in the “P” position.
• If the system detects any door (including the rear gate) open during operation, it will prevent starting or stopping the engine, and sound the horn and flash side marker lights, tail lights, and parking lights 6 times.
• In addition to the items above, if the vehicle’s engine management system determines there is a safety risk due to a vehicle-related problem, the vehicle will power down and the horn will sound 3 times.

NOTE

• If the alarm system is armed at the time of remote engine starter activation (the security indicator light on the combination meter is flashing), the alarm system will remain armed throughout the remote start run cycle.
• If the alarm system is disarmed at the time of remote engine starter activation (the security indicator light on the combination meter is not flashing), the alarm system will remain disarmed throughout the remote start run cycle.

Remote start operation  fob confirmation
Your remote engine starter fob is a bidirectional transceiver that can confirm system operation with several different visual and audible indications. The fob’s LED-backlit button and the internal piezo buzzer will indicate the status of the system using the following flash and beep sequences, provided the fob is within the operational range of the system.

System Maintenance

NOTE
For remote engine starter transceiver: In the event that the vehicle’s battery is replaced, discharged or disconnected, it will be necessary to start the vehicle a minimum of one time using the key prior to activating the remote engine start system. This is required to allow the vehicle’s electronic systems to resynchronize.

Changing the battery

• Do not let dust, oil or water get on or in the remote engine start transmitter when replacing the battery.
• Be careful not to damage the printed circuit board in the remote engine start transmitter when replacing the battery.
• Be careful not to allow children to touch the battery and any re-moved parts; children could swallow them.
• There is a danger of explosion if an incorrect replacement battery is used. Replace only with the same or equivalent type of battery.
• Battery should not be exposed to excessive heat such as sunshine, fire, or the like.

For remote engine starter transceiver:
The 3-volt lithium battery (model CR-2450) supplied in your remote engine start transmitter should last approximately one year, depending on usage. When the battery begins to weaken, you will notice a decrease in range (distance from the vehicle that your remote control operates). Follow the instructions below to change the remote engine start transmitter battery.

1. Remove the small Philips screw located on the back side lower left corner of the transmitter.
2. Carefully pry the remote engine start transmitter halves apart using a small flathead screwdriver.
   
3. Remove the circuit board from the bottom half of the case remove the battery and replace it with a new one. Be sure to observe the (+) sign on the old battery before removing it to ensure that the new battery is inserted properly (battery “+” should be pointed away from the transmitter circuit board on the battery).
   
4.  Carefully snap the case halves back together, reinstall the Philips screw, and test the remote engine start system.
