Traction Control System (TCS)
Your vehicle may have a Traction Control System (TCS)
that limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that one or both of the rear wheels are spinning or
beginning to lose traction. When this happens, the
system reduces engine power and may also upshift the
transmission to limit wheel spin.
You may feel or hear the system working, but this
is normal.
The TCS button is located
on your instrument panel.
Press this button to
turn the TCS off and on.
When the traction control system is turned off, an
indicator light on the button will illuminate.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
re-engage the cruise control. SeeCruise Control
on page 3-11.TCS operates in all transmission shift lever positions.
But the system can upshift the transmission only as
high as the shift lever position you have chosen, so
you should use the lower gears only when necessary.
SeeAutomatic Transmission Operation on page 2-21
and/orManual Transmission Operation on page 2-24
for more information.
If there is a problem with TCS, TRACTION FAULT will
be displayed on your Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 3-41for
more information.
When this warning is displayed, the system will not
limit wheel spin. Adjust your driving accordingly.
To limit wheel spin, especially in slippery road
conditions, you should always leave TCS on. But you
can turn the system off if you ever need to. You should
turn the system off if your vehicle ever gets stuck in
sand, mud or snow and rocking the vehicle is required.
SeeRocking Your Vehicle to Get It Out on page 4-42
andIf Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-42for more information.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modi cations
on page 5-3for more information.

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 are
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning does not 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 dimple the water’s
surface, there could be hydroplaning.
Hydroplaning usually happens at higher speeds. There
just is not 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 cannot 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. Do not ignore
police warning signs, and otherwise be very
cautious about trying to drive through owing
water.

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 will save time and energy.
SeeFreeway Driving on page 4-33.
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.
Freeway Driving
Mile for mile, freeways — also called thruways, parkways,
expressways, turnpikes, or superhighways — are the
safest of all roads. But they have their own special rules.
The most important advice on freeway driving is: Keep up
with traffic and keep to the right. Drive at the same speed
most of the other drivers are driving. Too-fast or too-slow
driving breaks a smooth traffic ow. Treat the left lane on
a freeway as a passing lane.

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 vehicle.
Also seeTires on page 5-52.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.
Driving on Snow or Ice
Most of the time, those places where the tires meet the
road probably have good traction.
However, if there is snow or ice between the tires and
the road, you can have a very slippery situation. You will
have a lot less traction, or grip, and will need to be very
careful.

{CAUTION:
If you spill fuel and then something ignites it,
you could be badly burned. Fuel can spray out
on you if you open the fuel cap too quickly.
This spray can happen if your tank is nearly
full, and is more likely in hot weather. Open
the fuel cap slowly and wait for any hiss noise
to stop. Then unscrew the cap all the way.
Be careful not to spill fuel. Do not top off or over ll the
tank and wait a few seconds after you have nished
pumping before removing the nozzle. Clean fuel from
painted surfaces as soon as possible. SeeWashing
Your Vehicle on page 5-92.
When replacing the fuel cap, turn it clockwise
until it clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed.This would allow fuel to evaporate into the atmosphere.
If the fuel cap is not properly installed, the FUEL CAP
message will appear on the Driver Information Center
(DIC) and the check engine light will be lit on the
instrument panel cluster. SeeDIC Warnings and
Messages on page 3-41andMalfunction Indicator
Lamp on page 3-32for more information.
{CAUTION:
If a re starts while you are refueling, do not
remove the nozzle. Shut off the ow of fuel
by shutting off the pump or by notifying the
station attendant. Leave the area immediately.
Notice:If you need a new fuel cap, be sure to get the
right type. Your dealer can get one for you. If you get
the wrong type, it may not t properly. This may
cause your malfunction indicator lamp to light and
may damage your fuel tank and emissions system.
SeeMalfunction Indicator Lamp on page 3-32.
