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
will not open it. You increase the chance
of being thrown out of the vehicle in a
crash if the doors are not 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.
2-10

There are several ways to lock and unlock your vehicle.
Because your vehicle has the theft-deterrent system,
you must unlock the doors with the key or remote
keyless entry transmitter to avoid setting off the alarm.
From the outside, use either the key or the remote
keyless entry transmitter.
From the inside, use the power door lock switches or
manual lock knobs. The manual lock knobs are located
at the top of the door panel near the window.
Push the manual lock knob down to lock the door. To
unlock the door, pull up on the knob.
Central Door Unlocking System
Your vehicle has a central door unlocking mode. When
unlocking the driver’s door, you can unlock the other
doors at the same time by turning the key clockwise in
the door lock cylinder twice.
Power Door Locks
The power door lock switches are located on the
armrest on the front doors.
K(Unlock):Press the side of the switch with the
unlock symbol to unlock the doors.
Q(Lock):Press the side of the switch with the lock
symbol to lock the doors.
Programmable Automatic
Door Locks
Your vehicle is programmed so that, when the doors are
closed, the ignition is on, and the shift lever is moved
out of PARK (P), all the doors will lock. The doors
will unlock every time you stop the vehicle and move
the shift lever into PARK (P).
If someone needs to get out while your vehicle is not
in PARK (P), have the person use the manual lock knob
or power door lock switch. When the door is closed
again, it will not lock automatically. Use the manual
lock knob or power door lock switch to lock the door.
With the vehicle in PARK (P) and the ignition on,
the door locks can be programmed through prompts
displayed on the Driver Information Center (DIC). These
prompts allow the driver to choose various lock and
unlock settings. For programming information, seeDIC
Vehicle Customization on page 3-88.

transmitter, the front door power lock switch, or
by lifting the rear door manual lock knob.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Turn the knob below the security lock label to the
horizontal position to disengage the lock.

switch is used to lock the doors, all doors will lock
and then the driver’s door will unlock. It is always
recommended that you remove the ignition key when
locking your vehicle.
The lockout protection feature can be overridden by
holding the power door lock switch for three seconds
or longer.
