2-35 Windshield Wipers
You control the windshield
wipers by turning the band
with the wiper symbol on it.
For a single wiping cycle, turn the band to MIST. Hold
it there until the wipers start, then let go. The wipers will
stop after one cycle. If you want more cycles, hold the
band on MIST longer.
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain or
snow. Turn the band to choose the delay time. The
closer to LOW, the shorter the delay.For steady wiping at low speed, turn the band to the
LOW position. For high
-speed wiping, turn the band
further, to HIGH. To stop the wipers, move the band
to OFF.
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do become
damaged, get new blades or blade inserts.
Heavy snow or ice can overload your wipers. The
windshield wiper motor is protected from overload by a
circuit breaker and a fuse. If the motor overheats due to
heavy snow or ice the wiper will stop until the motor
cools. Although the circuit is protected from electrical
overload, overload due to heavy snow or ice may cause
wiper linkage damage. Always clear ice and heavy snow
from the windshield before using your windshield wipers.

2-36 Windshield Washer
At the top of the lever, there's a paddle with the word
PUSH on it. To spray washer fluid on the windshield,
push the paddle.
CAUTION:
In freezing weather, don't use your washer until
the windshield is warmed. Otherwise the washer
fluid can form ice on the windshield, blocking
your vision.
Washer fluid will spray as long as you push the paddle.
When you let go of the paddle, the wipers will continue
to wipe for approximately two more wipe cycles and
then either stop or return to the preset speed.
Cruise Control (Option)
With cruise control, you can maintain a speed of about
25 mph (40 km/h) or more without keeping your foot
on the accelerator. This can really help on long trips.
Cruise control does not work at speeds below about
25 mph (40 km/h).
When you apply your brakes or move the cruise switch
to OFF, the cruise control shuts off.
CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.

Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button
at the end of the lever
and release it.
4. Take your foot off the
accelerator pedal.Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts off
the cruise control. But you don't need to reset it.
Once you're going about 25 mph (40 km/h) or more,
you can move the cruise control switch from ON to R/A
(Resume/Accelerate) briefly.
You'll go right back up to your chosen speed and
stay there.
If you hold the switch at R/A longer than half a second,
the vehicle will keep going faster until you release the
switch or apply the brake. So unless you want to go
faster, don't hold the switch at R/A.

Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:

Use the accelerator pedal to get to the higher speed.
Push the button at the end of the lever, then release
the button and the accelerator pedal. You'll now
cruise at the higher speed.

Move the cruise switch from ON to R/A. Hold it
there until you get up to the speed you want, and
then release the switch. To increase your speed in
very small amounts, move the switch to R/A briefly.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:

Push in the button at the end of the lever until you
reach the lower speed you want, then release it.

To slow down in very small amounts, push the
button briefly. Each time you do this, you'll go
1 mph (1.6 km/h) slower.Passing Another Vehicle While Using Cruise Control
Use the accelerator pedal to increase your speed. When
you take your foot off the pedal, your vehicle will slow
down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the hills. When
going up steep hills, you may have to step on the
accelerator pedal to maintain your speed. If the steepness
of the hill causes the vehicle speed to drop more than
15 mph (24 km/h) below the set speed, your cruise control
will automatically disengage. When going downhill, you
may have to brake or shift to a lower gear to keep your
speed down. Of course, applying the brake takes you out
of cruise control. Many drivers find this to be too much
trouble and don't use cruise control on steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:

Step lightly on the brake pedal; or

Move the cruise switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.

Exterior Lamps
Your parking lamp/headlamp switch is on the driver's
side of your instrument panel.
Your instrument panel dimmer thumbwheel has two
detent positions.
When the thumbwheel is moved to the first detent
position, the radio display and PRNDL display will go
to full intensity. The rest of the I/P illumination will stay
in the maximum dimming state. Moving the
thumbwheel up one more detent will activate the interior
dome lamps.The vehicle is also equipped with a DOME OVERRIDE
button. For more information on this feature see ªDome
Lampsº in the Index.
The delayed entry feature will allow you to enter or exit
your vehicle with the lights staying on for about
20 seconds, after the door is closed or ignition is cycled.
Turn the knob clockwise to the parking lamp symbol to
turn on:

Parking Lamps

Sidemarker Lamps

Taillamps

License Plate Lamps

Instrument Panel Lights

Ashtray Lamp
Turn the knob clockwise again to the master lighting
symbol to turn on all the lamps listed above as well as
the headlamps.
Turn the knob counterclockwise to OFF to turn off your
lamps and lights.
You can switch your headlamps from high to low beam
by pulling on the turn signal/high beam lever.

A circuit breaker protects your headlamps. If you have
an electrical overload, your headlamps will flicker on
and off. Have your headlamp wiring checked right away
if this happens.
Headlamps On Reminder
A tone will sound when your headlamps are turned on
and your ignition is in OFF, LOCK or ACCESSORY.
If you need to use your headlamps when the ignition
switch is in OFF, LOCK or ACCESSORY, the tone can
be turned off by moving the thumbwheel next to the
parking lamp/headlamp switch all the way down.
Daytime Running Lamps
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.The DRL system will make your headlamps come on at
a reduced brightness when:

The ignition is on,

The headlamp switch is off, and

The parking brake is released.
When the DRL are on, only your headlamps 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, your DRL indicator light is a
reminder to turn your headlamp switch on. The other
lamps that come on with your headlamps will also
come on.
When you turn off the headlamp switch, the regular
lamps will go off, and your headlamps will change to
the reduced brightness of DRL.
To idle your vehicle with the engine on and the DRL off,
set the parking brake. The DRL will stay off until you
release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-41 Center High-Mounted Stoplamp
Your vehicle's center high-mounted stoplamp is located
above the rear doors at the center of the vehicle.
If items are loaded on the roof of the vehicle, as in a
luggage carrier, care should be taken not to block or
damage the center high
-mounted stoplamp unit.
Interior Lamps
Dome Lamps
The dome lamps will come on when you open the doors.
You can also turn the dome lamps on by moving the
thumbwheel, located next to the headlamp knob, all the
way up to the second notch. In this position, the dome
lamps will remain on whether the doors are open
or closed.

yellowblue
2-42
You can use the DOME OVERRIDE button, located
below the headlamp knob, to set the dome lamps to
automatically come on when the doors are open, or to
remain off.
If the DOME OVERRIDE button is pushed in, the dome
lamps will not come on.
If the DOME OVERRIDE button is out, your interior
lamps will work as usual.
If the button is pressed in, the interior lamps will not
come on when any of the vehicle's doors are open. This
feature is helpful when you want to leave your door(s)
open for an extended period of time and do not want to
run the battery down. The button is located next to the
lamp switch.Reading Lamps (Option)
If your vehicle has reading lamps, press the button next
to the lamp to turn the lamp on or off.

Mirrors
Inside Day/Night Rearview Mirror
Pull the tab under the mirror toward you to reduce
glare from headlamps behind you after dark. Push
the tab away from you to restore the mirror to the
original position.
Outside Mirrors
Adjust your outside mirrors so you can just see the
side of your vehicle, and have a clear view of objects
behind you. Some mirrors can be folded in to enter
narrow doorways.
Electric Outside Rearview Mirrors (Option)
If you have electric mirrors, they can be adjusted from
inside the vehicle.
Select the mirror you want
to move by rotating the
switch clockwise to adjust
the passenger's side mirror
and counterclockwise to
adjust the driver's side
mirror. The center position
is neutral.
Then, adjust the mirror angle by pressing the outer
arrows on the switch until the mirror is adjusted where
you want it.

2-44
Heated Outside Rearview Mirrors (If Equipped)
Your outside mirrors can be
defrosted by pressing the
button near the fan control.
An indicator light in the button will illuminate anytime
the heated outside rearview mirrors are activated.
If your vehicle has a rear window defogger, see ªRear
Window Defoggerº in the Index.
Convex Outside Mirror
Your passenger's side mirror may be convex. A convex
mirror's surface is curved so you can see more from the
driver's seat.
CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder before
changing lanes.
