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.
To unlock the door form the outside, use the keyless
entry system or the key.
To unlock the door from
the inside, slide the manual
lever forward. To lock the
door, slide the manual
lever rearward.

switch, marked L on either
front door to lock all the
doors at once.
Press the recessed side of the switch marked U to unlock
all the doors at once.
On the passenger side of the
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.
Programmable Locks
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.
Lockout Prevention
This feature protects you from locking your key in
the vehicle when the key is in the ignition and a door
is open.
If the power lock switch is pressed when 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.

You will find a security lock lever on the inside edge of
each rear door. Your vehicle may be equipped with one
of the two labels shown.With this feature, you can lock the rear doors so they
cannot be opened from the inside by passengers. To use
the security locks do the following:
1. Open one of the rear doors.
2. Move the lever up to engage the security lock.
Move the lever down to disengage the security lock.
3. Close the door.
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
