Move the switch to OFF to turn off the rear
window washer.
The rear window washer uses the same uid bottle as
the front windshield washer. If the uid level is low in the
washer bottle, you may not be able to wash your rear
window. If you can wash your windshield, but not
your rear window, check the uid level.
Cruise Control
Your vehicle may have this feature. 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, the cruise control
shuts off.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not 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. Do not use cruise
control on slippery roads.
3-11

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/Acclerate) briey.
You’ll go right back up to your chosen speed and
stay there.
If you hold the switch at R/A, 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. Press 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
briey. Each time you do this, your vehicle will go
about 1 mph (1.6 km/h) faster.
3-13

Reducing Speed While Using Cruise
Control
There are two ways to reduce your speed while using
cruise control:
Press 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, press the
button briey. Each time you do this, you’ll go
about 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 want to step
on the accelerator pedal to maintain your speed.
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 nd 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.
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.

Headlamps 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
rst 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 rst 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:
1. Turn the ignition to RUN.
2. 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.
3-16

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 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. SeeDaytime Running Lamps (DRL) on
page 3-16for more information.
As with any vehicle, you should turn on the regular
headlamps when you need them.
Instrument Panel Brightness
The thumbwheel for this feature is located to the right of
the exterior lamps control. Turn the thumbwheel up to
brighten the lights or down to dim them.
Moving the thumbwheel up to the rst position will
activate the interior dome lamps.
3-17

You can only drive for a short time with the readings in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.This light should come on
briey when you turn the
ignition key to RUN. If
it doesn’t come on then,
have it xed so it will
be ready to warn you if
there’s a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeTowing
Your Vehicle on page 4-32.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning light
on can lead to an accident. If the light is still
on after you have pulled off the road and
stopped carefully, have the vehicle towed
for service.
3-30

Anti-Lock Brake System
Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on
for several seconds.
That’s normal.
If the light stays on, or comes on when you’re driving,
your vehicle needs service. If the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes. If the regular brake
system warning light is also on, you don’t have anti-lock
brakes and there’s a problem with your regular
brakes. See “Brake System Warning Light” earlier in
this section.
The anti-lock brake system warning light should come
on briey when you turn the ignition key to RUN. If
the light doesn’t come on then, have it xed so it will be
ready to warn you if there is a problem.
Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature. If the gage
pointer moves to the
red area, your engine is
too hot!
It means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-29.

Your Driving, the Road, and
Your Vehicle
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please start with a very important safety device in your
vehicle: Buckle up. SeeSafety Belts: They Are for
Everyone on page 1-12.
Defensive driving really means “be ready for anything.”
On city streets, rural roads, or freeways, it means
“always expect the unexpected.”
Assume that pedestrians or other drivers are going to
be careless and make mistakes. Anticipate what
they might do. Be ready for their mistakes.
Rear-end collisions are about the most preventable of
accidents. Yet they are common. Allow enough following
distance. It is the best defensive driving maneuver, in
both city and rural driving. You never know when
the vehicle in front of you is going to brake or turn
suddenly.
Defensive driving requires that a driver concentrate on
the driving task. Anything that distracts from the
driving task — such as concentrating on a cellular
telephone call, reading, or reaching for something onthe oor — makes proper defensive driving more
difficult and can even cause a collision, with resulting
injury. Ask a passenger to help do things like this, or
pull off the road in a safe place to do them yourself.
These simple defensive driving techniques could save
your life.Drunken Driving
Death and injury associated with drinking and driving is
a national tragedy. It is the number one contributor
to the highway death toll, claiming thousands of victims
every year.
Alcohol affects four things that anyone needs to drive
a vehicle:
Judgment
Muscular Coordination
Vision
Attentiveness
Police records show that almost half of all motor
vehicle-related deaths involve alcohol. In most cases,
these deaths are the result of someone who was
drinking and driving. In recent years, more than
16,000 annual motor vehicle-related deaths have been
associated with the use of alcohol, with more than
300,000 people injured.
4-2

{CAUTION:
Drinking and then driving is very dangerous.
Your reexes, perceptions, attentiveness,
and judgment can be affected by even a
small amount of alcohol. You can have a
serious — or even fatal — collision if you drive
after drinking. Please do not drink and drive or
ride with a driver who has been drinking. Ride
home in a cab; or if you are with a group,
designate a driver who will not drink.
Control of a Vehicle
You have three systems that make your vehicle go
where you want it to go. They are the brakes, the
steering, and the accelerator. All three systems have
to do their work at the places where the tires meet
the road.
Sometimes, as when you are driving on snow or ice, it
is easy to ask more of those control systems than
the tires and road can provide. That means you can lose
control of your vehicle.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about three-fourths of
a second. But that is only an average. It might be less
with one driver and as long as two or three seconds
or more with another. Age, physical condition, alertness,
coordination and eyesight all play a part. So do
alcohol, drugs and frustration. But even in three-fourths
of a second, a vehicle moving at 60 mph (100 km/h)
travels 66 feet (20 m). That could be a lot of distance in
an emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road (whether it is pavement
or gravel); the condition of the road (wet, dry, icy); tire
tread; the condition of your brakes; the weight of
the vehicle and the amount of brake force applied.
Avoid needless heavy braking. Some people drive
in spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic.
