Panic Alarm Button
When the panic button with the horn symbol on
the keyless entry transmitter is pressed, the horn will
sound and the headlamps and taillamps will flash for up
to 30 seconds. This can be turned off by pressing the
panic button again, waiting for 30 seconds, or starting
the vehicle.
Matching Transmitter(s) to Your Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can be
purchased through your dealer. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to
touch any of the circuitry. Static from your
body transferred to these surfaces may damage
the transmitter.

Tilt Wheel (If Equipped)
A tilt steering wheel allows you to adjust the steering
wheel before you drive. You can also raise it to the
highest level to give your legs more room when you exit
and enter the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the steering wheel and pull the
lever. Move the steering wheel to a comfortable level,
then release the lever to lock the wheel in place.
Turn Signal/Multifunction Lever
The lever on the driver's side of the steering column
includes the following:

Turn and Lane Change Signals

Headlamp High/Low
-Beam Changer

Flash
-to-Pass

Windshield Wipers

Windshield Washer

Cruise Control (Option)
For information on the exterior lamps, see ºExterior
Lampsº later in this section.

2-35 Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, pull the multifunction lever all the way toward
you. Then release it.
When the high beams are
on, this indicator light
located on the instrument
panel cluster also will be on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are in automatic.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are in automatic or on low beam,
your high
-beam headlamps will turn on. They'll stay
on as long as you hold the lever toward you and the
high
-beam indicator located on the cluster comes on.
Release the lever to return to normal operation.
Windshield Wipers
To operate the windshield
wipers turn the band,
located on the multifunction
lever, upward or downward.
MIST: Turn the band to MIST for a single wiping cycle.
Hold it there until the windshield wipers start, then let it
go. The wipers will stop after one wipe. If you want
more wipes, hold the band on mist longer.

The exterior lamp control has three positions:
(Off): Turning the control to this position turns off all
lamps except the Daytime Running Lamps (DRL).
(Parking Lamps):Turning the control to this
position turns on the parking lamps, together with the
following:

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights

Ashtray Lamp
(Headlamps): Turning the control to this position
turns on the headlamps, together with the previously
listed lamps and lights.
Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as the
taillamps, sidemarker, parking lamps and the instrument
panel lights. The radio lights will also be dim.Your vehicle is equipped with a light sensor on the top
of the instrument panel in the defroster grille. Be sure it
is not covered, or the system will be on whenever the
ignition is on.
The system may also turn on your headlamps when
driving through a parking garage, heavy overcast
weather or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation of the Daytime Running Lamps
(DRL) and the automatic headlamp systems so that
driving under bridges or bright overhead street lights
does not affect the system. The DRL and automatic
headlamp system will only be affected when the light
sensor sees a change in lighting lasting longer than
the delay.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
You may be able to turn off your automatic headlamp
system. SeeªDaytime Running Lamps (DRL)º later
in this section for more information.
As with any vehicle, you should turn on the regular
headlamps when you need them.

2-42 Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on and your ignition
is in OFF, LOCK or ACCESSORY. To disable the tone,
turn the instrument panel brightness thumbwheel all the
way down. In the automatic mode, the headlamps turn
off once the ignition key is in OFF.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset. Fully
functional daytime running lamps are required on all
vehicles first sold in Canada.
The DRL system will make your headlamps come on at a
reduced brightness when the following conditions are met:

The ignition is on,

the exterior lamp control is OFF.

the automatic transmission is not in PARK (P),

the light sensor determines it is daytime and

the parking brake is released.When the DRL are on, only your DRL lamps will be on.
The taillamps, sidemarker and other lamps won't be on.
Your instrument panel won't be lit up either.
When it begins to get dark, the automatic headlamp
system will switch from DRL to the headlamps or the
last chosen headlamp setting that was used.
To idle your vehicle with the DRL off, put the
transmission in PARK (P). The DRL will stay off
until you shift out of PARK (P).
The following does not apply to vehicles first sold
in Canada.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following the steps below:

Turn the ignition to RUN.

Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you that the
system is off.

To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(the chime will sound), or turn the ignition to OFF
and then to RUN again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Here are some tips on night driving.

Drive defensively.

Don't drink and drive.

Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.

Since you can't see as well, you may need to
slow down and keep more space between you and
other vehicles.

Slow down, especially on higher speed roads. Your
headlamps can light up only so much road ahead.

In remote areas, watch for animals.

If you're tired, pull off the road in a safe place
and rest.
No one can see as well at night as in the daytime. But as
we get older these differences increase. A 50
-year-old
driver may require at least twice as much light to see the
same thing at night as a 20
-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes will
have less trouble adjusting to night. But if you're
driving, don't wear sunglasses at night. They may cut
down on glare from headlamps, but they also make a lot
of things invisible.You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even
several seconds, for your eyes to readjust to the dark.
When you are faced with severe glare (as from a driver
who doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your windshield and all the glass on your vehicle
clean
-- inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from night
blindness
-- the inability to see in dim light -- and
aren't even aware of it.

CAUTION:
Snow can trap exhaust gases under your vehicle. This
can cause deadly CO (carbon monoxide) gas to get
inside. CO could overcome you and kill you. You
can't see it or smell it, so you might not know it is in
your vehicle. Clear away snow from around the base
of your vehicle, especially any that is blocking your
exhaust pipe. And check around again from time
to time to be sure snow doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will help
keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well
-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible.Preserve the fuel as long as you can. To help keep warm,
you can get out of the vehicle and do some fairly vigorous
exercises every half hour or so until help comes.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle
-- such as behind a motorhome.
The two most common types of recreational vehicle towing
are known as ªdinghy towingº (towing your vehicle with
all four wheels on the ground) and ªdolly towingº (towing
your vehicle with two wheels on the ground and two wheels
up on a device known as a ªdollyº).
Your vehicle was not designed to be towed with any of
its wheels on the ground. If your vehicle must be towed,
see ªTowing Your Vehicleº in the Index.
NOTICE:
Towing an all±wheel±drive vehicle with all four
wheels on the ground, or even with only two of its
wheels on the ground, will damage drivetrain
components. Don't tow an all±wheel±drive
vehicle if any of its wheels will be on the ground.
