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: 808481  Size: A2

The trunk lock release button is located on the left side of the instrument panel below the lamp controls.

Press the trunk lock release button upward to open the trunk. To use this feature, your vehicle must be in PARK (P) or NEUTRAL (N) and the valet lockout switch must be in the OFF position.

You can also press the button with the trunk symbol on the remote keyless entry transmitter to open the trunk. To disable this feature, see Valet Lockout Switch under Theft-Deterrent Systems .

Trunk Lid Tie Down

Caution: Driving with the trunk lid open can allow dangerous CO (carbon monoxide) gas to come into your vehicle. You can not see or smell CO. It can cause unconsciousness and even death. If you ever need to drive with your trunk lid open, then:

   • Make sure all windows, the rear seat pass-through and sunroof are closed.
   • Turn the fan on your heating and cooling system to its highest speed, with the setting on AUTO and temperature between 65°F (18°C) and 85°F (29°C). This forces fresh outside air into your vehicle.
   •  Open all air ducts on the instrument panel.
Do not use the trunk lid tie down if you are towing a trailer because of the danger of CO.
