Caution: Exhaust gases can enter the vehicle if it is driven with the liftgate, trunk/hatch open, or with any objects that pass through the seal between the body and the trunk/hatch or liftgate. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death.

If the vehicle must be driven with the liftgate, or trunk/hatch open:

   • Close all of the windows.
   • Fully open the air outlets on or under the instrument panel.
   • Adjust the Climate Control system to a setting that brings in only outside air and set the fan speed to the highest setting. See Climate Control System in the Index.
   • If the vehicle is equipped with a power liftgate, disable the power liftgate function.
For more information about carbon monoxide, see Engine Exhaust.

Trunk Lock Release


Object Number: 1530597  Size: A2

The remote trunk release button is located on the lower portion of the driver door.

To use the remote trunk release, the shift lever must be in P (Park) or N (Neutral) for a vehicle with an automatic transmission. The shift lever must be in N (Neutral), with the parking brake set for a vehicle with a manual transmission.

Press the button to open the trunk. You can also press the button with the trunk symbol on the Remote Keyless Entry (RKE) transmitter to open the trunk.

With the Keyless Access System, when you have the transmitter, the trunk can be opened by the trunk release button located on the rear of the trunk above the license plate. The vehicle must be in P (Park) and the valet mode turned off.

If the vehicle is locked, the keyless access transmitter must be within 3 feet (1 meter) of the trunk opening for it to be recognized and allow the trunk to open.

If the vehicle is ever without power, the trunk area can still be accessed by using one of the following procedures.

On vehicles with a rear seat pass-through door:

  1. Fold the rear armrest down and open the pass-through door. See "Rear-Seat Pass Through" following for more information.

Close the trunk by pulling on the handle. Do not use the handle as a tie-down.

Rear-Seat Pass Through

If the vehicle has the rear seat-pass through door, the trunk can be accessed through the rear seat. This is useful when transporting long items.

To open the door, pull down the rear seat armrest. Then pull the lever all the way down to release the door.

To close the door, push it up and back into place. Then try to open the door without pulling up on the lever to make sure it is locked into place.

Emergency Trunk Release Handle


Object Number: 808272  Size: B3

Notice: Do not use the emergency trunk release handle as a tie-down or anchor point when securing items in the trunk as it could damage the handle. The emergency trunk release handle is only intended to aid a person trapped in a latched trunk, enabling them to open the trunk from the inside.

There is a glow-in-the-dark emergency trunk release handle located on the back wall of the trunk. This handle will glow following exposure to light. Pull the release handle toward the front of the vehicle to open the trunk from the inside.
