Liftgate
{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death.
If you must drive with the liftgate open, or if
electrical wiring or other cable connections
must pass through the seal between the body
and the liftgate:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the
recirculation mode off. That will force
outside air into your vehicle. See Climate
Control System in the index.
If you have air outlets on or under the
instrument panel, open them all the way.

will continue to completion. If you shift the transmission
out of PARK (P) and accelerate before the power
liftgate latches closed, the liftgate may reverse to the
open position. Cargo could fall out of the vehicle. Always
make sure the power liftgate is closed and latched
before you drive away.
If you power open the liftgate and the liftgate support
struts have lost pressure, the lights will ash and a
chime will sound. The liftgate will stay open temporarily,
then slowly close. See your dealer/retailer for service
before using the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle during a power
open or close cycle, a warning chime will sound and the
liftgate will automatically reverse direction to the full
closed or open position. After removing the obstruction,
the power liftgate operation can be used again. If the
liftgate encounters multiple obstacles on the same power
cycle, the power function will deactivate, and you
must manually open or close the liftgate. The LIFTGATE
OPEN warning message in the Driver Information
Center (DIC) will indicate that the liftgate is open. After
removing the obstructions, manually open the liftgate
to the full open position or close the liftgate to the fully
closed and latched position. The liftgate will now
resume normal power operation. Power Liftgate Button Near Liftgate Latch

pedal must be applied.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the key.
Use the correct key and turn the key only with your
hand. Make sure the key is all the way in. If none of
this works, then your vehicle needs service.
A (LOCK/OFF):This is the only position in which you
can remove the key. This position locks the ignition and
transmission. If the steering wheel is locked, move it from
right to left and turn the key to ACC/ACCESSORY. If
none of this works, then your vehicle needs service.B (ACC/ACCESSORY):This position allows you to use
things like the radio and the windshield wipers while
the engine is off. This position will also allow you to turn
off the engine.
C (ON/RUN):This is the position that the switch returns
to after you start your engine and release the key.
The switch stays in ON/RUN when the engine is
running. But even when the engine is not running, you
can use ON/RUN to operate your electrical power
accessories, and to display some instrument panel
warning lights.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the
engine off. You may not be able to start your vehicle if
the battery is allowed to drain for an extended period
of time.
D (START):This position starts the engine. When the
engine starts, release the key. The ignition switch
will return to ON/RUN for normal driving.
