2003 CHEVROLET CAVALIER warning light

This light will come on when your Enhanced Traction
System is limiting wheel spin. SeeEnhanced Traction
System Active Light on page 3-29.
You may feel or hear the system working, but this is
normal.
When the transaxle shift lever is in any position other
than FIRST (1) or SECOND (2) and the parking brake is
fully released, this warning light will come on to let
you know if there's a problem with the system.See
Enhanced Traction System Warning Light on
page 3-28. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.
The Enhanced Traction System can operate when the
transaxle shift lever is in any position other than
FIRST (1) or SECOND (2). To limit wheel spin,
especially in slippery road conditions, you should
use REVERSE (R), THIRD (3) or AUTOMATIC
OVERDRIVE (D). See
Automatic Transaxle Operation
on page 2-22. If your vehicle ever gets stuck in
sand, mud or snow and rocking the vehicle is required,
see
If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-29.
When you move the shift lever to FIRST (1) or
SECOND (2), the system will turn off. The Enhanced
Traction System warning light will come on and stay on.
If the Enhanced Traction System is limiting wheel
spin when you move the shift lever to another position,
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 moving
the shift lever to any position other than FIRST (1) or
SECOND (2). The Enhanced Traction System warning
light should go off. United States

Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the
water. This can happen if the road is wet enough and
you're going fast enough. When your vehicle is
hydroplaning, it has little or no contact with the road.
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 re¯ections
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 ¯owing water, as you
might at a low water crossing, your vehicle can
be carried away. As little as six inches of
¯owing 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 ¯owing 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. SeeTires
on page 5-51
.

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.
4-19

Winter Driving
Here are some tips for winter driving:
·Have your vehicle in good shape for winter.
·You may want to put winter emergency supplies in
your trunk.Include an ice scraper, a small brush or broom, a
supply of windshield washer ¯uid, a rag, some winter
outer clothing, a small shovel, a ¯ashlight, a red
cloth and a couple of re¯ective 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.

Engine Coolant
The cooling system in your vehicle is ®lled with
DEX-COOLžengine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs ®rst, if you add
only DEX-COOL
žextended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem
with engine overheating, see
Engine Overheating on
page 5-25.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC).
·Give boiling protection up to 265ÉF (129ÉC).
·Protect against rust and corrosion.
·Help keep the proper engine temperature.
·Let the warning lights and gages work as they
should.
Notice:When adding coolant, it is important that
you use only DEX-COOLž(silicate-free) coolant.
If coolant other than DEX-COOLžis added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the engine
coolant will require change sooner Ð at 30,000 miles
(50,000 km) or 24 months, whichever occurs ®rst.
Damage caused by the use of coolant other
than DEX-COOL
žis not covered by your new vehicle
warranty.
What to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOLžcoolant which won't damage
aluminum parts. If you use this coolant mixture,
you don't need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will.
CAUTION: (Continued)
5-22

The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the FULL
COLD mark.
If the low coolant light
comes on and stays on, it
means you're low on
engine coolant. See
Low
Coolant Warning Light
on page 3-30
.
Adding Coolant
If you need more coolant, add the proper DEX-COOLž
coolant mixtureat the surge tank, but only when the
engine is cool. If the surge tank is empty, a special ®ll
procedure is necessary. See
Engine Overheating
on page 5-25for instructions on ªHow to Add Coolant to
the Coolant Surge Tank.º
{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.
Coolant Surge Tank Pressure Cap
Notice:Your pressure cap is a pressure-type
cap and must be tightly installed to prevent coolant
loss and possible engine damage from overheating.
See ªCapacities and Speci®cationsº for more
information.
5-24

Engine Overheating
You will ®nd a coolant temperature gage and a low
coolant warning light on your vehicle's instrument panel.
See
Engine Coolant Temperature Gage on page 3-29andLow Coolant Warning Light on page 3-30.
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 ®re. You
or others could be badly burned. Stop your
engine if it overheats, and get out of the
vehicle until the engine is cool.
Notice:If your engine catches ®re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.

If No Steam Is Coming From Your
Engine
An overheat warning, along with a low coolant light, can
indicate a serious problem. SeeLow Coolant Warning
Light on page 3-30.
If you get an engine overheat warning with no low
coolant light, but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a
little too hot when you:
·Climb a long hill on a hot day.
·Stop after high-speed driving.
·Idle for long periods in traffic.
·Tow a trailer.If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning doesn't come back on, you can drive
normally.
If the warning continues and you have not stopped, pull
over, stop, and park your vehicle right away.
If there's still no sign of steam, you can idle the engine
for three minutes while you're parked. If you still
have the warning,
turn off the engine and get everyone
out of the vehicleuntil it cools down.
You may decide not to lift the hood but to get service
help right away.
