Doors and Locks
Door Locks
{WARNING:
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. The chance of being thrown out of the
vehicle in a crash is increased if the doors are
not locked. So, all passengers should wear
safety belts properly and the doors should be
locked whenever the vehicle is driven.
•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 the vehicle whenever
leaving 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.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
PASS-Key®III+ Electronic
Immobilizer
SeeRadio Frequency Statement on page 8-18for
information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry and Science Canada.
PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle is equipped with the PASS-Key®III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III+ is a passive
theft deterrent system.
The system is automatically armed when the key is
removed from the ignition.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it shuts down the vehicle’s
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. Anyone
using a trial-and-error method to start the vehicle will be
discouraged because of the high number of electrical
key codes.
If the engine does not start and the security message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.
3-20
Page 125 of 424

If the engine still does not start, and the key appears to
be undamaged, try another ignition key. At this time,
you may also want to check the instrument panel PASS
KEY fuse. If the engine still does not start with the
other key, your vehicle needs service. If your vehicle
does start, the first key may be faulty. See your
dealer/retailer or a locksmith who can service the
PASS-Key
®III+ to have a new key made. SeeFuses
and Circuit Breakers on page 6-104.
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.
This procedure is for learning additional keys only.
If all the currently programmed keys are lost or do not
operate, you must see your dealer/retailer or a locksmith
who can service PASS-Key
®III+ to have keys made
and programmed to the system.
See your dealer/retailer 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.To program the new key:
1. Verify the new key has
1stamped on it.
2. Insert the original, already programmed key into
the ignition lock cylinder and start the engine.
If the engine will not start, see your dealer/retailer
for service.
3. After the engine has started, turn the key to
LOCK/OFF and remove the key.
4. Insert the key to be programmed and turn it to
ON/RUN within 10 seconds of removing the
previous key.
The security message will turn off once the key has
been programmed. It may not be apparent that
the security message went on due to how quickly
the key is programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you lose or damage a PASS-Key
®III+ key, see
your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
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 the 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 5-26for the trailer towing
capabilities of the vehicle and more information.
Following break-in, engine speed and load can
be gradually increased.
Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
and the regular brake pedal applied.
A (LOCK/OFF):This position locks the ignition and
transmission. You will only be able to remove the key
when the ignition is turned to LOCK/OFF.
Notice:Using a tool to force the key to turn in
the ignition could cause damage to the switch or
break the key. Use the correct key, make sure it
is all the way in, and turn it only with your hand.
If the key cannot be turned by hand, see your
dealer/retailer.
3-22
Page 127 of 424

B (ACC/ACCESSORY):This is the position in which
you can operate things like the radio and the windshield
wipers when the engine is off.
C (ON/RUN):This position can be used to operate the
electrical accessories and to display some instrument
panel cluster warning and indicator lights. The switch
stays in this position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle if the
battery is allowed to drain for an extended period of time.
D (START):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
•Audio System
•Power Windows (if equipped)
These features will work when the ignition key is in
ON/RUN or ACC/ACCESSORY. Once the key is turned
from ON/RUN to LOCK/OFF, power to the radio will
continue to work 10 minutes or until the driver door is
opened. The power windows will continue to work for up
to 10 minutes or until any door is opened.
Starting the Engine
If the vehicle has the DURAMAX®Diesel engine, see
the DURAMAX®Diesel manual for more information.
To place the transmission in the proper gear:
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
the engine when the vehicle is already moving,
use N (Neutral) only.
