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.

Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning,
you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each
of us is subject to
the same laws of physics when driving on curves.
The traction of the tires against the road surface makes
it possible for the vehicle to change its path when
you turn the front wheels.
If there’s no traction, inertia
will keep the vehicle going in the same direction.
If
you’ve ever tried to steer a vehicle on wet ice, you’ll
understand this.
The traction you can get in a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While
you’re in a curve, speed is the one factor you can
control.

Hydroplaning doesn’t happen often. But it can if your Driving Through Flowing Water
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
“dimple” 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. Fla
ng or rushi - ater 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
e 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 Tires
on page 5-53.

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, “Freeway Driving.”
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.

How to Reset the Change Oil Light
The GM Oil Life SystemTM calculates when to change
your engine oil and filter based on vehicle use. Anytime
your oil is changed, reset the system
so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE OIL light being turned on, reset the system.
After changing the engine oil, the system must be reset.
To reset the oil life indicator, do the following steps:
1. With the ignition key in ON (a short time after
turning
off the engine), press the RESET button
located in the driver's side instrument panel
fuse block. See "Instrument Panel Fuse Block"
under
Fuses and Circuit Breakers on page 5-81.
2. When the CHANGE OIL light starts to flash, press
and hold the RESET button again.
The reset
is complete when you hear the chimes and
the CHANGE
OIL light goes out.
If your vehicle is equipped with a 2.2L L4 ECOTEC
engine, it has a unique oil filter element. When
reinstalling the filter cap do not exceed
18 Ib ft (25 N*m ).
Inspect the condition of the O-ring and replace if
damaged.
See your dealer for additional information.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don't let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose
of clothing or
rags containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from the
filter before disposal. Never dispose of oil by putting it
in the trash, pouring it on the ground, into sewers, or into
streams or bodies of water. Instead, recycle it by
taking it to a place that collects used oil.
If you have a
problem properly disposing of your used
oil, ask
your dealer, a service station or a local recycling center
for help.

When to Check and What to Use
Schedule to determine
how often you should
check the fluid level in your
master cylinder reservoir
and for the proper
fluid. See
Part B: Owner
Checks and Services
on page 6-9 and Part D:
Recommended Fluids
and Lubricants
on
page 6- 15.
How to Check and Add Fluid
You do not need to check the fluid level unless you
suspect a clutch problem. To check the fluid level, take
the cap
off. If the fluid level reaches the top of the
reservoir, the fluid level is correct. It isn’t a good idea to
top
off your clutch fluid. Adding fluid won’t correct a
leak. A fluid loss in this system could indicate a problem
Have the system inspected and repaired.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL@ engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add
only DEX-COOL@ extended 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 5-26.
A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (1 29°C).
@ Protect against rust and corrosion.
@ Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.

3400 V6 Engine similar
The coolant surge tank
is located in the engine
compartment on the passenger’s side of the vehicle.
See
Engine Compartment Overview on page 5-12
for more information on location. Turning
the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn
you badly. Never turn the surge tank pressure
cap
- even a little - when the engine and
radiator are hot.
The vehicle must be on
a level surface. When your
mgine is cold, the coolant level should be at the
FULL
;OLD mark, or a little higher.
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 3-31 for more
nformation.

Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture
at the surge tank, but only when the
engine is cool.
If the surge tank is empty, a special fill
procedure is necessary. See
Engine Overheating
on page
5-26 and “How to Add Coolant to the Coolant
Surge Tank under
Cooling System on page 5-28
for instructions.

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.
Notice: If your engine catches fire because you
keep driving with no coolant, your vehicle can
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. See
Low Coolant Warning
Light
on page 3-31.
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.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
