injuries or even death from heat stroke. Never
leave a child alone in a vehicle, especially with
the windows closed in warm or hot weather.

The power window controls are located on the side of
both the front doors and the rear doors.
The driver's door has a switch for the passenger
windows as well. Your power windows will work when
the ignition has been turned to ACCESSORY or RUN or
when Retained Accessory Power (RAP) is active. See
ªRetained Accessory Powerº in the Index.Press the rear of the switch with the power window
symbol on it to lower the window or the front of the

Door Locks
CAUTION:
Unlocked doors can be dangerous.

Passengers -- especially children -- can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle won't open it. You increase the
chance of being thrown out of the vehicle in
a crash if the doors aren't locked. So, wear
safety belts properly and lock the doors
whenever you drive.

Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.

Outsiders can easily enter through an
unlocked door when you slow down or stop
your vehicle. Locking your doors can help
prevent this from happening.
There are several ways to lock and unlock your vehicle.
Use the keyless entry system.
You can also use your key.
To lock the door from
the inside, slide the
manual lever rearward.
To unlock the door,
slide the manual
lever forward.

switch, marked ªLº on
either front door to lock
all the doors at once.

liftgate opening trim there is
a power lock switch which
can be used to lock or
unlock all of the doors.The power door locks will operate at any time without
the ignition being on.
If the rear lock switch is pressed with the rear doors
open, all of the doors will lock five seconds after the
cargo doors are closed.
The power door locks can be programmed to
automatically lock and unlock depending on the settings
you have chosen in the secondary information center
(SIC). See ªSecondary Information Centerº in the Index
for more information.
Operating the power locks may interact with the
theft
-deterrent system. See ªContent Theft-Deterrentº
in the Index.

the vehicle when the key is in the ignition and a door
is open.

and the key is in the ignition, all of the doors will lock
and then the driver's door will unlock.

With this feature, you can
lock the rear doors so they
can't be opened from the
inside by passengers. To
use the security locks:

of the rear door. Move the lever up to engage the
security lock. Move the lever down to disengage
the security lock.

4. Do the same thing to the other rear door.
The rear doors on your vehicle cannot be opened from
the inside when this feature is in use. If you want to
open the rear door when the security lock is on, unlock
the door and open the door from the outside.

to use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
