Section 2 Features and Controls

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.
If your vehicle has a Driver Information Center
(DIC), you can choose various lock and unlock settings.
For programming information, seeDIC Vehicle
Customization on page 3-65.
Rear Door Security Locks
Your vehicle has rear door security locks. These
prevent passengers from opening the rear doors from
the inside.
The rear door security
locks are located on the
inside edge of each
rear door. You must open
the rear doors to
access them.
To set the locks, do the following:
1. Insert the key into the security lock slot and turn it
so the slot is in the horizontal position.
2. Close the door.
2-13

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if the vehicle has one, the power
door lock switch, or by lifting the rear door
manual lock.
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. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If the key is in the ignition and the power door 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.
Trunk
{CAUTION:
It can be dangerous to drive with the trunk lid
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 trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
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. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-31.
2-14

Remote Trunk Release
The remote trunk release
button is located in the
glovebox.
Press the button to open the trunk. To use this feature,
your vehicle must be in PARK (P) or NEUTRAL (N).
You can also press the remote trunk release button on
the Remote Keyless Entry (RKE) transmitter to open
the trunk. SeeRemote Keyless Entry System Operation
on page 2-6.
Emergency Trunk Release Handle
Notice:Do not use the emergency trunk release
handle as a tie-down or anchor point when securing
items in the trunk as it could damage the handle.
The emergency trunk release handle is only
intended to aid a person trapped in a latched trunk,
enabling them to open the trunk from the inside.
There is a glow-in-the-dark emergency trunk release
handle located inside the trunk near the latch. This
handle will glow following exposure to light. Pull
the release handle to open the trunk from the inside.

PASS-Key®III+ Operation
Your vehicle is equipped with PASS-Key®III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not have to
do anything special to arm or disarm the system. It
works when you insert or remove the key from
the ignition.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster comes on, the key may have a damaged
transponder. Turn the ignition off and try again.If the engine still does not start, and the key appears to
be not damaged, try another ignition key. At this
time, you may also want to check the fuse, seeFuses
and Circuit Breakers on page 5-93. If the engine
still does not start with the other key, your vehicle needs
service. If your vehicle does start, the rst key may be
faulty. See your dealer who can service the
PASS-Key
®III+ to have a new key made. In an
emergency, contact Roadside Assistance. SeeRoadside
Assistance Program on page 7-6.
It is possible for the PASS-Key
®III+ decoder to “learn”
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle. The
following procedure is for programming additional
keys only. If all the currently programmed keys are lost
or do not operate, you must see your dealer or a
locksmith who can service PASS-Key
®III+ to have keys
made and programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
2-20

To program the new key do the following:
1. Verify that the new key has a
1stamped on it.
2. Insert the already programmed key in the ignition
and start the engine. If the engine will not start, see
your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to the
RUN position within ve seconds of the original key
being turned to the OFF position.
5. The security light will turn off once the key has
been programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If you are ever driving and the security light comes on
and stays on, you may be able to restart your engine if
you turn it off. Your PASS-Key
®III+ system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
PASS-Key
®III+ system at this time.
If you lose or damage your PASS-Key
®III+ key, see
your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-36for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
