Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the frontal
air bags inflate (if battery power is available). You can
lock the doors again and turn the interior lamps off by
using the door lock and interior lamp controls.
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, 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 has a crash sensing and diagnostic
module, which records information about the air bag
and related systems. It records information about the
readiness of the air bag systems, when the sensors
are activated and driver's safety belt usage at
deployment or in a near
-deployment crash. Some
modules also record speed, engine RPM, brake and
throttle data.
Let only qualified technicians work on your air bag
systems. Improper service can mean that an 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, or the air bag
covering on the driver's and right front
passenger's door, the bag may not work properly.
You may have to replace the air bag module in
the steering wheel, both the air bag module and
the instrument panel for the right front
passenger's air bag, or both the air bag module
and door panel for the driver's and right front
passenger's side impact air bag. Do not open or
break the air bag coverings.

With the ignition key in the ignition switch, you can turn
the switch to five different positions.
ACCESSORY (A): This position lets you use things
like the radio and the windshield wipers when the
engine is off. To get into ACCESSORY, push in the key
and turn it toward you. The steering wheel will remain
locked, just as it was before you inserted the key.
LOCK (B): Before you put the key in, the ignition will
be in LOCK. This is the only position in which you can
remove the key. This position locks the ignition, steering
wheel and transaxle. It's a theft
-deterrent feature.
NOTICE:
If your key seems stuck in LOCK and you can't
turn it, be sure you are using the correct key; if
so, is it all the way in? If it is, then turn the
steering wheel left and right while you turn the
key hard. But turn the key only with your hand.
Using a tool to force it could break the key or the
ignition switch. If none of this works, then your
vehicle needs service.
OFF (C): This position lets you turn off the engine but
still turn the steering wheel. It doesn't lock the steering
wheel like LOCK does. Use OFF if you must have your
vehicle in motion while the engine is off (for example, if
your vehicle is being pushed).
RUN (D): This position is for driving.
START (E): This position starts the engine.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned from
RUN to OFF:

Radio

Power Windows

Sunroof
Power to these accessories stops after 10 minutes or
if any door is opened. If you want power for another
10 minutes, turn the ignition key to RUN, then back
to OFF, then to LOCK. Always leave your key in
LOCK when using RAP. If you leave your key in
any other position than LOCK, your battery will
discharge prematurely.

Express-Down Window
This feature is present on the driver's power window.
Pressing the control rearward into the second position then
releasing it will lower the window completely. If you want
to stop the window as it is lowering, press the control
forward. Press the control forward to raise the window.
Note: The first position on the power window
control operates the driver's power window in the
non
-express mode.
Rear Window Lockout
This button is located near
the power window controls
on the driver's side. Pressing
this button down will disable
the rear window controls.
This is a useful feature if you
have children as passengers.
Press the button again to
allow your passengers to
reuse their window controls.
Horn
The horn can be sounded by pressing on the center of
the steering wheel pad.
Tilt Wheel
Tilt steering allows you to adjust the steering wheel
before you drive. Raising the steering wheel to the
highest level gives your legs more room when you enter
and exit the vehicle.
Hold the steering wheel and pull the lever toward you to tilt
the wheel. Adjust the steering wheel to a comfortable
position and then release the lever to lock the wheel
in place.

To turn the system off, press
the TRAC OFF button
located inside the
glove box.
The TRACTION OFF message will display on the
Driver Information Center. If the system is limiting
wheel spin when you press the button, the TRACTION

-- but the system won't turn
off right away. It will wait until there's no longer a
current need to limit wheel spin.
You can turn the system back on at any time by pressing
the button again. The TRACTION READY message
should display briefly on the Driver Information Center.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Steering
Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Magnasteer

This system continuously adjusts the effort you feel
when steering at all vehicle speeds. It provides ease
when parking yet a firm, solid feel at highway speeds.
Steering Tips
Driving on Curves
It's important to take curves at a reasonable speed.
A lot of the ªdriver lost controlº accidents mentioned on
the news happen on curves. Here's why:
Experienced driver or beginner, each of us is subject to
the same laws of physics when driving on curves. The
traction of the tires against the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there's no traction, inertia will keep
the vehicle going in the same direction. If you've ever
tried to steer a vehicle on wet ice, you'll understand this.

Adding Coolant
If you need more coolant, add the proper DEX
-COOL

coolant mixture at the surge tank, but only when the
engine is cool.
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.
When replacing the pressure cap, make sure it is
hand
-tight.
Power Steering Fluid
The power steering fluid
reservoir is located next to
the engine coolant surge
tank on the passenger's side
of the engine.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
