2-64 Anti-Lock Brake System Warning Light
United States Canada
With the anti
-lock brake system, the light will come on
when your engine is started and may stay on for three
seconds. That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you're driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while 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 ªBrake System
Warning Lightº earlier in this section.The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Enhanced Traction System Warning Light
With the Enhanced Traction
System (ETS), this warning
light should come on briefly
as you start the engine.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem.
If the warning light stays on, or comes on when you're
driving, there may be a problem with your Enhanced
Traction System and your vehicle may need service.
When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.

2-65
The Enhanced Traction System warning light may come
on for the following reasons:

If you turn the system off by pressing the ETS button
on the center console near the gear shift lever, the
warning light will come on and stay on. To turn the
system back on, press the button again. The warning
light should go off. See ªEnhanced Traction Systemº
in the Index for more information.

If the traction control system is affected by an
engine
-related problem, the system will turn off
and the warning light will come on.

If the vehicle is driven on an extremely rough road, the
warning light may come on momentarily but will go
off again when the vehicle leaves the rough surface.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
system is turned on and the parking brake is fully
released, your vehicle needs service.
Enhanced Traction System Active Light
When your Enhanced
Traction System is
limiting wheel spin,
this light will come on.
Slippery road conditions may exist if the Enhanced
Traction System active light comes on, so adjust your
driving accordingly.
The light will stay on for a few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes
on briefly when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
there to tell you when the system is active.

2-66 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, the light comes on
and you hear a chime, your
engine is too hot. It means
that your engine coolant has
overheated.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
This light comes on briefly
when you turn your ignition
on.
If this light comes on and stays on and you hear a chime,
the coolant level in your vehicle is low. See ªEngine
Coolantº in the Index. If the light is on along with an
overheat warning, you may have a serious overheating
problem. See ªEngine Coolant Temperature Gageº listed
previously.
NOTICE:
Damage to your engine from neglected coolant
problems can be costly and is not covered by your
warranty.
See ªEngine Overheatingº in the Index for information
on what to do. Your vehicle should be serviced as soon
as possible.

2-67 Low Tire Pressure Light (If Equipped)
The tire pressure
monitor system can
alert you to a large
change in the pressure
in one tire.
After the system has ªlearnedº tire pressures with
properly inflated tires, the LOW TIRE PRESSURE light
will come on if the pressure in one tire becomes 12 psi
(83 kPa) lower than the other three tires. The tire
pressure monitor system won't alert you if the pressure
in more than one tire is low, if the system is not yet
calibrated, or if the vehicle is moving at less than 15
mph (25 km/h), faster than
75 mph (120 km/h), on rough roads or during turns.
The light may also come on if you are driving on
partially cleared pavement.When the LOW TIRE PRESSURE light comes on, you
should stop as soon as you can and check all your tires
for damage. (If a tire is flat, see ªIf a Tire Goes Flatº in
the Index.) Also check the tire pressure in all four tires
as soon as you can. See ªInflation
- Tire Pressureº in
the Index.
The light will stay on (while the ignition is on) until you
reset (calibrate) the system. See ªTire Pressure Monitor
Systemº in the Index.
The LOW TIRE PRESSURE light also comes on
briefly when you turn the ignition key to ON. If the
light doesn't come on then, have it fixed so it will be
there to tell you if the pressure in a tire is low or high.
If the anti
-lock brake system warning light comes on,
the tire pressure monitor system may not be working.
See your dealer for service. Also, see ªAnti
-Lock Brake
System Warning Lightº in the Index.

Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic.
This is a mistake. Your brakes may not have time to
cool between hard stops. Your brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary
braking. That means better braking and longer
brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and the
brake pedal will be harder to push.
Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine, or when you begin to
drive away, your anti
-lock brake system will check
itself. You may hear a momentary motor or clicking
noise while this test is going on, and you may even
notice that your brake pedal moves or pulses a little.
This is normal.

If there's a problem with the anti
-lock brake system,
this warning light will stay on. See ªAnti
-Lock Brake
System Warning Lightº in the Index.

The Enhanced Traction System operates in all transaxle
shift lever positions. But the system can upshift the
transaxle only as high as the shift lever position you've
chosen, so you should use the lower gears only when
necessary. See ªAutomatic Transaxleº in the Index.
When the system is on and
the parking brake is fully
released, this warning light
will come on to let you
know if there's a problem.
See ªEnhanced Traction System Warning Lightº in the
Index. When this warning light is on, the system will not
limit wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave the Enhanced
Traction System on. But you can turn the system
off if you prefer.
To turn the system on or off,
press the ETS button on the
center console.
When you turn the system off, the Enhanced Traction
System warning light will come on and stay on. If the
Enhanced Traction System is limiting wheel spin
when you press the button to turn the system off,
the warning light will come on and the indicator light
will go off
-- 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 Enhanced Traction System
warning light should go off.

Hydroplaning doesn't happen often. But it can if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops ªdimpleº the
water's surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn't a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining.
Driving Through Deep Standing Water
NOTICE:
If you drive too quickly through deep puddles
or standing water, water can come in through
your engine's air intake and badly damage your
engine. Never drive through water that is slightly
lower than the underbody of your vehicle. If you
can't avoid deep puddles or standing water, drive
through them very slowly.
Driving Through Flowing Water
CAUTION:
Flowing or rushing water creates strong forces.
If you try to drive through flowing water, as you
might at a low water crossing, your vehicle can
be carried away. As little as six inches of flowing
water can carry away a smaller vehicle. If this
happens, you and other vehicle occupants could
drown. Don't ignore police warning signs, and
otherwise be very cautious about trying to drive
through flowing water.
Some Other Rainy Weather Tips

Besides slowing down, allow some extra following
distance. And be especially careful when you pass
another vehicle. Allow yourself more clear room
ahead, and be prepared to have your view restricted
by road spray.

Have good tires with proper tread depth. See ªTiresº
in the Index.

City Driving
One of the biggest problems with city streets is the
amount of traffic on them. You'll want to watch out
for what the other drivers are doing and pay attention
to traffic signals.Here are ways to increase your safety in city driving:

Know the best way to get to where you are
going. Get a city map and plan your trip into
an unknown part of the city just as you would
for a cross
-country trip.

Try to use the freeways that rim and crisscross
most large cities. You'll save time and energy.
See the next part, ªFreeway Driving.º

Treat a green light as a warning signal. A traffic light
is there because the corner is busy enough to need it.
When a light turns green, and just before you start
to move, check both ways for vehicles that have not
cleared the intersection or may be running the
red light.

4-26
Include an ice scraper, a small brush or broom, a supply
of windshield washer fluid, a rag, some winter outer
clothing, a small shovel, a flashlight, a red cloth and a
couple of reflective warning triangles. And, if you will
be driving under severe conditions, include a small bag
of sand, a piece of old carpet or a couple of burlap bags
to help provide traction. Be sure you properly secure
these items in your vehicle.
Driving on Snow or Ice
Most of the time, those places where your tires meet
the road probably have good traction.
However, if there is snow or ice between your tires
and the road, you can have a very slippery situation.
You'll have a lot less traction or ªgripº and will need
to be very careful.

5-9
Engine Overheating
You will find a coolant temperature gage and a low
coolant warning light on your vehicle's instrument
panel. See ªEngine Coolant Temperature Gageº and
ªLow Coolant Warning Lightº in the Index.
If Steam Is Coming From Your Engine
CAUTION:
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn it off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire.
You or others could be badly burned. Stop your
engine if it overheats, and get out of the vehicle
until the engine is cool.
