If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you
want the vehicle to go. If you start steering quickly
enough, your vehicle may straighten out. Always
be ready for a second skid if it occurs.
Of course, traction is reduced when water, snow,
ice, gravel, or other material is on the road.
For safety, you will want to slow down and adjust
your driving to these conditions. It is important
to slow down on slippery surfaces because
stopping distance will be longer and vehicle
control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration,
or braking, including reducing vehicle speed by
shifting to a lower gear. Any sudden changes could
cause the tires to slide. You may not realize the
surface is slippery until your vehicle is skidding.
Learn to recognize warning clues — such as
enough water, ice, or packed snow on the road
to make a mirrored surface — and slow down
when you have any doubt.
Remember: Any Anti-Lock Brake System (ABS)
helps avoid only the braking skid.Racing or Other Competitive Driving
See your warranty book before using your
vehicle for racing or other competitive driving.
Notice:If you use your vehicle for racing or
other competitive driving, the engine may
use more oil than it would with normal
use. Low oil levels can damage the engine.
For information on how to add oil, see
Engine Oil on page 333.
Z06 Only: Be sure to check the oil level often
during racing or other competitive driving
and keep the level at or near the upper mark
that shows the proper operating range on
the engine oil dipstick.
Except Z06: Be sure to check the oil level
often during racing or other competitive driving
and keep the level at or near 1 quart (1 L)
above the upper mark that shows the proper
operating range on the engine oil dipstick.
After the competitive driving, remove excess
oil so that the level on the dipstick is not
above the upper mark that shows the proper
operating range.

Before Leaving on a Long Trip
Make sure you are ready. Try to be well rested.
If you must start when you are not fresh — such
as after a day’s work — do not plan to make
too many miles that rst part of the journey.
Wear comfortable clothing and shoes you can
easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it is ready to go. If it
needs service, have it done before starting out.
Of course, you will nd experienced and able
service experts in GM dealerships all across
North America. They will be ready and willing to
help if you need it.Here are some things you can check before a trip:Windshield Washer Fluid:Is the reservoir
full? Are all windows clean inside and outside?
Wiper Blades:Are they in good shape?
Fuel, Engine Oil, Other Fluids:Have you
checked all levels?
Lamps:Are they all working? Are the
lenses clean?
Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough
for long-distance driving? Are the tires
all inated to the recommended pressure?
Weather Forecasts:What is the weather
outlook along your route? Should you
delay your trip a short time to avoid a major
storm system?
Maps:Do you have up-to-date maps?

Checking Engine Oil (Except Z06)
If the CHECK OIL LEVEL message on the Driver
Information Center (DIC) comes on, check the
engine oil level right away. For more information,
seeDriver Information Center (DIC) on page 207.
You should check the engine oil level regularly;
this is an added reminder.
It is a good idea to check the engine oil level
every time you get fuel. In order to get an accurate
reading, the oil must be warm and the vehicle
must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 330
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil a few
minutes to drain back into the oil pan. If
you do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a
lint-free paper towel or a cloth, then push
it back in all the way. Remove it again,
keeping the tip down.

Z06 models have a racetrack-ready dry sump
engine lubrication system. This high-performance
system operates differently than a standard
engine lubrication system and requires a special
procedure when checking the engine oil level.
Follow this procedure closely when checking the
engine oil level.
