{CAUTION:
If your vehicle is facing downward on a steep
grade (15 percent or more), the door may not
stay open and could slam shut, possibly
injuring someone. To make sure the door does
not slam shut, turn on the power sliding door
feature. Then if the door closes, it will close
under the control of the power door system.
If you want to close the power sliding door(s) when the
override switch(es) is turned off, pull the inside or
outside handle or the edge of the door. Move the door
about 4 inches (10 cm) toward the closed position
and release it. The door will close completely and latch
for you.
To close the power sliding door(s) when the override
switch(es) is turned on, pull the inside or outside handle
and slide the door all the way forward to the latched
position.

fuse or the underhood fuse 8, 27, or 29 are
removed or blown.
SeeFuses and Circuit Breakers on page 5-92for more
information about your fuse panel.
If any of these conditions occur, the power sliding door
will need to be reset. If your vehicle has the dual
power sliding doors, both doors will have to be reset.
To reset a door, do the following:
1. Check to be sure the power sliding door is unlocked
and securely closed.

{CAUTION:
It can be dangerous to drive with the liftgate
open because carbon monoxide (CO) gas can
come into your vehicle. You can’t 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 and select the
control setting that will force outside air
into your vehicle. SeeClimate Control

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may have a theft-deterrent alarm system.
A light located on top of your instrument panel, near the
center of the vehicle next to the windshield, will ash
slowly to let you know that the system has been armed.While armed, the doors will not unlock with the power
door lock switch.
Once armed, the alarm will go off if someone tries to
enter the vehicle without using the remote keyless entry
transmitter or a key, or turns the ignition to ON. The
horn will sound and the parking lamps will ash for up to
two minutes.
When the alarm is armed, the liftgate may be opened
with the remote keyless entry transmitter.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
door lock switch to lock the doors while any door or
the liftgate is open and the key is removed from
the ignition. If you would like to turn on power door lock
switch arming, seeVehicle Personalization on
page 2-55.
When the security light ashes quickly the system is
ready to arm with the power door lock switches.
Then the security light will stop ashing and stay on
when you press the rear of the power door lock switch,
to let you know the system is arming. After all doors
and the liftgate are closed and locked, the security light
will begin ashing at a very slow rate to let you know
the system is armed.
