Doors and Locks
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.
There are several ways to lock and unlock your vehicle.From the outside:

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.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.
The security light is
located on the instrument
panel cluster.
If the ignition is off and a door is open, the security
light will ash, reminding you to arm the theft-deterrent
system.

transmitter. If the door is closed when the lock button
is pressed, the security light will stay illuminated
for 30 seconds. After the security light goes off, the
theft-deterrent system is armed. Pressing the lock
button twice will arm the system immediately.
If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is open
or not closed completely, the security light will ash
for 60 seconds and then turn off. The theft-deterrent
system is armed but the alarm will not sound if
the trunk lid, hood or door that was not closed
completely is tampered with or opened. The alarm
will sound for the trunk lid, hood or a door that was
completely closed at the time the vehicle was locked
using the keyless access transmitter.
Exit the vehicle and lock the door with the power
door lock switch or lock button on the keyless access
transmitter. The security light should ash. Close the
door. The security light will stop ashing and stay
on. After 30 seconds the light should turn off, the
theft-deterrent system is armed.
If Passive Arming is activated through the vehicle
personalization feature, the system will arm
automatically after you close the door and take at
least one keyless access transmitter with you. The
security light will turn on. After 60 seconds the light
should turn off. The theft-deterrent system is armed.
SeeVehicle Personalization on page 2-61.
If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will ash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
The Theft-Deterrent system will not arm if:
The key is used to turn the key cylinder to the lock
position.
The driver’s door is locked using the power door
lock switch after the doors are closed.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft-deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. SeeVehicle Personalization
on page 2-61.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver’s door
disarms the theft-deterrent system. Unlocking a door
any other way while the system is armed will activate
the alarm.

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:
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 (Vehicles Without Heavy Duty Cooling) on
page 4-31orTowing a Trailer (Vehicles With
Heavy Duty Cooling) on page 4-32for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
