Starting the Engine

(Hybrid Only)

Warning
Shifting out of P (Park) with the hood open, into any gear, may cause the vehicle to move. To help avoid serious injury to yourself or others, be sure the vehicle remains in P (Park) while the hood remains open.

Caution
Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.
If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment 0 303.

Hybrid Starting Procedure

1. With the Keyless Access system, the Remote Keyless Entry (RKE) transmitter must be in the vehicle. Press ENGINE START/STOP with the brake pedal applied. When the engine begins cranking, let go of the button.
   The idle speed will go down as the engine gets warm. Do not race the engine immediately after starting it.
   If the RKE transmitter is not in the vehicle, if there is interference, or if the RKE battery is low, a Driver Information Center (DIC) will display a message. See Key and Lock Messages 0 171 and Remote Keyless Entry (RKE) System Operation 0 35.
   Caution Cranking the engine for long periods of time, by returning the ignition to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down.
2. If the engine does not start after five to 10 seconds, especially in very cold weather (below −18 °C or 0 °F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there as you press ENGINE START/STOP. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, release the accelerator. If the vehicle starts briefly but then stops again, do the same thing. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.

When the state of charge is low and the hood is open, the vehicle may not start. Close the hood and follow the starting procedure again.
The vehicle will emit an audible startup beep when the vehicle is ready to be driven. When the vehicle ready light is on in the instrument cluster, the vehicle is ready to be driven. This could take up to 15 seconds at extremely cold temperatures. See Vehicle Ready Light (Hybrid Only) 0 149.

Hybrid Operation
This vehicle combines gasoline and electric propulsion. The gasoline engine will automatically start to provide power and then shut off to save fuel.
The engine may remain running when:

• Accelerating aggressively or climbing hills.
• Vehicle speed is greater than 125 km/h (75 mph).
• Charging the high voltage battery.
• The heater is being used.
  The engine and transmission work together to provide propulsion power at the highest efficiency. This may result in higher engine speeds.

Stop/Start System
Warning Exiting the vehicle without first shifting into P (Park) may cause the vehicle to move. You or others may be injured. Because the vehicle may have an auto engine stop/start feature, the vehicle’s engine might seem to be shut off; however, once the brake pedal is released, the engine will start up again. Shift to P (Park) and turn the ignition off before exiting the vehicle.

Auto Engine Stop/Start
When the brakes are applied and the vehicle is at a complete stop, the engine may turn off. When stopped,
the tachometer may display Auto  Stop, or the Auto Stop light may come on in the instrument cluster. See Tachometer 0 132 and Auto Stop Mode (Uplevel Cluster) 0 148. When the brake pedal is released or the accelerator pedal is pressed, the engine may restart.
Auto Stop may be deactivated if:

• A minimum vehicle speed is not reached.
• The engine or transmission is not at the required operating temperature.
• The outside temperature is not in the required operating range, typically between -10 °C (14 °F) and 50 °C (122 °F).
• The shift lever is in any gear other than D (Drive).
• The battery has been recently disconnected.
• The battery charge is low.
• The interior comfort level has not reached the required level for the climate control system or defog settings.
  See Automatic Climate Control System (Quad Zone – Gasoline Only) 0 199 or Automatic Climate Control System (Dual Zone – Gasoline and Hybrid) 0 206.
• The Auto Stop time is greater than two minutes.
• With the hood open, the engine will be in an Auto Stop. The driver may force the engine on when the hood is open, by completely pressing the accelerator pedal for Whenhcomes on green in the
  instrument cluster, the system is active. The system is not active when it comes on white with a slash through it.  at least two seconds.

Engine Heater
Vehicles with the engine coolant heater can use this option in cold weather conditions at or below −18 ° C (0 °F) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting your vehicle. An internal thermostat in the plug-end of the cord may exist which will prevent engine coolant heater operation at temperatures above −18 °C (0 °F).

To Use the Engine Coolant Heater

1. Turn off the engine.
2. Open the hood and unwrap the electrical cord. The cord is clipped to the diagonal brace on the passenger side of the engine compartment.
   Check the heater cord for damage. If it is damaged, do not use it. See your dealer for a replacement. Inspect the cord for damage yearly.
3. Plug it into a normal, grounded 110-volt AC outlet.

Warning
Improper use of the heater cord or an extension cord can damage the cord and may result in overheating and fire.

• Plug the cord into a three-prong electrical utility receptacle that is protected by a ground fault detection function. An ungrounded outlet could cause an electric shock.
• Use a weatherproof, heavy-duty, 15 amp-rated extension cord if needed. Failure to use the recommended extension cord in good operating condition, or using a damaged heater or extension cord, could make it overheat and cause a fire, property damage, electric shock, and injury.
• Do not operate the vehicle with the heater cord permanently attached to the vehicle. Possible heater cord and thermostat damage could occur.
• While in use, do not let the heater cord touch vehicle parts or sharp edges. Never close the hood on the heater cord.
• Before starting the vehicle, unplug the cord, reattach the cover to the plug, and securely fasten the cord. Keep the cord away from any moving parts.

Retained Accessory Power (RAP)

These vehicle accessories can be used for up to 10 minutes after the engine is turned off:

• Audio System
• Power Windows Sunroof (if equipped)
  Power to the audio system will work up to 10 minutes or until the driver door is opened. Power to the windows or sunroof will work up to 10 minutes or until any door is opened.

Shifting Into Park
To shift into P (Park):

1. Hold the brake pedal down and set the parking brake. See Electric Parking Brake 0 243.
2. Move the shift lever into P (Park) by holding in the button on the shift lever and pushing the lever all the way toward the front of the vehicle.
3. Turn the ignition off.
4. Take the Remote Keyless Entry (RKE) transmitter with you. Leaving the Vehicle with the Engine Running

Warning
It can be dangerous to leave the vehicle with the engine running. It could overheat and catch fire. It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll.
Do not leave the vehicle when the engine is running. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park 0 232. If you are towing a trailer, see Driving Characteristics and Towing Tips 0 298.

If you have to leave the vehicle with the engine running, the vehicle must be in P (Park) and the parking brake set. After shifting into P (Park), try to move the shift lever out without first pushing the button on the shift lever. If you can, the shift lever was not fully locked into P (Park).

Torque Lock

Torque lock is when the weight of the vehicle puts too much force on the parking pawl in the transmission. This happens when parking on a hill and shifting the transmission into P (Park) is not done properly and then it is difficult to shift out of P (Park). To prevent torque lock, set the parking brake and then shift into P (Park). To find out how, see “Shifting Into Park” listed previously.
If torque lock does occur, the vehicle may need to be pushed uphill by another vehicle to relieve the parking pawl pressure, so you can shift out of P (Park).

Shifting out of Park
This vehicle is equipped with an electronic shift lock release system.
The shift lock release is designed to prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN and the brake pedal is applied.
The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9 volt) battery.
If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump-starting the battery. See Jump Starting – North America 0 377 for more information.

To shift out of P (Park):

1. Apply the brake pedal.
2. Release the parking brake. See Electric Parking Brake 0 243.
3. Press the shift lever button.
4. Move the shift lever.

If unable to shift out of P (Park):

1. Fully release the shift lever button.
2. While holding down the brake pedal, press the shift lever button again.
3. Move the shift lever.
   If the shift lever will not move from P (Park), consult your dealer or a professional towing service.
