Air bags are designed to inate only once. After they
inate, you’ll need some new parts for your air bag
system. If you don’t get them, the air bag system
won’t be there to help protect you in another crash.
A new system will include air bag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module, which records information about
the air bag system. The module records information
about the readiness of the system, when the system
commands air bag ination and driver’s safety belt
usage at deployment. The module also records
speed, engine rpm, brake and throttle data.
Let only qualied technicians work on your air bag
system. Improper service can mean that your air bag
system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, the bag
may not work properly. You may have to replace
the air bag module in the steering wheel or both
the air bag module and the instrument panel for
the right front passenger’s air bag. Do not open or
break the air bag coverings.
Servicing Your Air Bag-Equipped
Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don’t want the system to
inate while someone is working on your vehicle.
Your dealer and the service manual have information
about servicing your vehicle and the air bag system.
To purchase a service manual, seeService Publications
Ordering Information on page 7-12.
{CAUTION:
For up to 10 minutes after the ignition key is
turned off and the battery is disconnected, an
air bag can still inate during improper service.
You can be injured if you are close to an air bag
when it inates. Avoid wires wrapped with
yellow tape or yellow connectors. They are
probably part of the air bag system. Be sure to
follow proper service procedures, and make
sure the person performing work for you is
qualied to do so.
The air bag system does not need regular maintenance.

double-sided key for the
ignition and door locks.
It will t with either
side up.
When a new vehicle is delivered, the dealer
provides the owner with a pair of identical keys
and a bar-coded tag.The bar-coded tag has a code on it that tells your
dealer or a qualied locksmith how to make extra keys.
Keep this tag in a safe place. If you lose your keys,
you’ll be able to have new ones made easily using
this tag.
Notice:If you ever lock your keys in your vehicle,

Power Door Locks
If your vehicle has power
door locks, press the
power door lock switch
located on the door panel
to lock or unlock all the
doors at once.
The power door lock switch will lock or unlock the rear
hatch and Dutch doors. See “Hatch Release” in
Rear Doors on page 2-12.
When a door is locked, the inside door handle will not
open the door. This will help stop a door from being
accidentally opened.
If the sliding door is open and you press the power door
lock switch, the sliding door will not lock immediately.
After you close the door, the system comes on and locks
the sliding door in about ve seconds.
When the key is in the ignition and the power door lock
switch is pressed with a door open, all doors are
locked while the driver’s side door remains unlocked.
Programmable Automatic
Door Locks
Your vehicle is equipped with an auto lock/unlock feature
which enables you to program your power door locks.
Your vehicle left the factory programmed to have all the
doors lock automatically when the shift lever is moved out
of PARK (P). All of the doors will unlock when the shift
lever is moved back into PARK (P). The following
instructions detail how to program your door locks.
To enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then, pull back on the
turn signal/multifunction lever all the way toward you
and hold it while you perform the next step.
2. Turn your key to RUN and OFF twice. Then, with
the key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock
switch lock and unlock.
You are now ready to program the automatic door locks.
Select one of the following four programming options and
follow the instructions. You will have thirty seconds to
begin programming. If you exceed the thirty second limit,
the locks will automatically lock and unlock to indicate
that you have left the program mode. If this occurs, repeat
the procedure beginning with Step 1. You can exit the
program mode any time by turning the ignition to RUN.

Theft-Deterrent Systems
Vehicle theft is a big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can
make it impossible to steal. However, there are ways
you can help.
Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock
®is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will
go off approximately ve seconds after the key is
turned to RUN.If the engine stalls and the SECURITY light ashes,
wait until the light stops ashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine if you turn
the engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®at
this time. You may also want to check the fuse.
SeeFuses and Circuit Breakers on page 5-101.
See your dealer for service.

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:
Keep your speed at 55 mph (88 km/h) or
less for the rst 500 miles (805 km).
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km).
Do not make full-throttle starts.
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 4-35for more information.
Ignition Positions
With the key in the ignition, you can turn it to
ve different positions.
A (ACCESSORY):This position lets you use things
like the radio, power windows and windshield wipers
when the engine is off. To get into ACCESSORY,
push in the key and turn it toward you.
2-18

Page 95 of 386

Notice:Lengthy operation of features such
as the radio in the accessory ignition position
may drain the battery and prevent your vehicle
from starting. Do not operate your vehicle in
the accessory ignition position for a long period
of time.
B (LOCK):This position locks your ignition and
transmission. It’s a theft-deterrent feature. You will
only be able to remove your key when the ignition is
turned to LOCK.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only
with your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.C (OFF):This position lets you turn off the engine.
Use OFF if you must have your vehicle in motion
while the engine is off (for example, if your vehicle is
being towed).
D (RUN):This is the position for driving.
E (START):This position starts your engine.
Retained Accessory Power (RAP)
Your vehicle is equipped with a Retained Accessory
Power (RAP) feature which will allow certain features
on your vehicle to continue to work up to 20 minutes
after the ignition key is turned to OFF.
Your radio, power windows and overhead console will
work when the ignition key is in RUN or ACCESSORY.
Once the key is turned from RUN to OFF, these
features will continue to work for up to 20 minutes or
until a door is opened.

Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won’t start in any other position – that’s a
safety feature. To restart when you’re already moving,
use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage
the transmission. Shift to PARK (P) only when
your vehicle is stopped.
1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down
as your engine gets warm.
Notice:Holding your key in START for longer
than 15 seconds at a time will cause your battery
to be drained much sooner. And the excessive
heat can damage your starter motor. Wait about
15 seconds between each try to help avoid draining
your battery or damaging your starter.
2. If it doesn’t start within 10 seconds, push the
accelerator pedal all the way to the oor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.When starting your engine in very cold weather
(below 0°F or−18°C), do this:
1. With your foot off the accelerator pedal, turn
the ignition key to START and hold it there up
to 15 seconds. When the engine starts, let go
of the key.
2. If your engine still won’t start (or starts but then
stops), it could be ooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
oor and holding it there as you hold the key in
START for about three seconds. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briey but then stops again, do the
same thing, but this time keep the pedal down
for ve or six seconds. This clears the extra
gasoline from the engine.
Notice:Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way the
engine operates. Before adding electrical equipment,
check with your dealer. If you do not, your engine
might not perform properly.
