Instruments and Controls 4-33
Of course, traction is reduced when
water, snow, ice, gravel, or other
material is on the road. For safety,
slow down and adjust your driving
to these conditions. It is important
to slow down on slippery surfaces
because stopping distance is 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 might not
realize the surface is slippery until
the 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 Antilock Brake
System (ABS) helps avoid only
the braking skid.Competitive Driving
Competitive driving may affect the
vehicle warranty. See the warranty
book before using the vehicle for
racing or other competitive driving.
The new vehicle break-in must be
performed before the vehicle is used
for competitive driving. SeeNew
Vehicle Break-In on page 8-16.
Notice:If you use your vehicle
for competitive driving, the engine
may use more oil than it would
with normal use. Low oil levels
can damage the engine. Be sure
to check the oil level often during
competitive driving and keep the
level at or near the upper mark
that shows the proper operating
range on the engine oil dipstick.
For information on how to add oil,
seeEngine Oil on page 9-10.For competitive driving, it is
recommended that the brake fluid be
replaced with a high performance
brake fluid that has a dry boiling point
greater than 279°C (534°F). After
conversion to the high performance
brake fluid, follow the brake fluid
service recommendations outlined
by the fluid manufacturer. Do not
use silicone or DOT-5 brake fluids.
If the vehicle is used for racing,
competitive driving, sustained high
speed, or events that generate
excessive wheel slip, the rear axle
fluid temperatures will be higher
than would occur in normal driving.
We recommend that the rear axle
fluid be drained and refilled with
new fluid after every six hours of
racing or competitive driving.
SeeRecommended Fluids and
Lubricants on page 10-7for what
fluid to use.
Driving and Operating 8-7
To prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch
to ACC/ACCESSORY or
LOCK/OFF.
Notice:Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start
after 5-10 seconds, especially in
very cold weather (below 0°F or
−18°C), it could be flooded with
too much gasoline. Push the
accelerator pedal all the way to
the floor and holding it there as
you hold the key in START for a
maximum of 15 seconds. Wait atleast 15 seconds between each
try, to allow the cranking motor to
cool. When the engine starts, let
go of the key and accelerator.
If the vehicle starts briefly but
then stops again, repeat the
procedure. This clears the extra
gasoline from the engine. Do not
race the engine immediately after
starting it. Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Notice:The engine is designed
to work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the engine operates.
Before adding electrical
equipment, check with your
dealer/retailer. If you do not,
the engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.Engine Heater
The engine coolant heater, if
available, can help in cold weather
conditions at or below 0°F (−18°C)
for easier starting and better fuel
economy during engine warm-up.
Plug in the coolant heater at least
four hours before starting the vehicle.
An internal thermostat in the
plug-end of the cord will prevent
engine coolant heater operation at
temperatures above 0°F (−18°C).
8-20 Driving and Operating
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications.
See the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, the vehicle will operate
satisfactorily on fuels meeting federal
specifications, but emission control
system performance might be
affected. The malfunction indicator
lamp could turn on and the vehicle
might fail a smog-check test.
SeeMalfunction Indicator Lamp
on page 4-19. If this occurs, return
to your authorized dealer/retailer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs might not be
covered by the vehicle warranty.
Fuels in Foreign
Countries
If you plan on driving in another
country outside the United States
or Canada, the proper fuel might
be hard to find. Never use leaded
gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs caused by
use of improper fuel would not be
covered by the vehicle warranty.
To check the fuel availability, ask
an auto club, or contact a major oil
company that does business in the
country where you will be driving.
Fuel Additives
To provide cleaner air, all gasolines
in the United States are now required
to contain additives that help prevent
engine and fuel system deposits
from forming, allowing the emission
control system to work properly.
In most cases, you should not have
to add anything to the fuel. However,
some gasolines contain only theminimum amount of additive
required to meet U.S. Environmental
Protection Agency regulations.
To help keep fuel injectors and
intake valves clean, or if the vehicle
experiences problems due to dirty
injectors or valves, look for gasoline
that is advertised as TOP TIER
Detergent Gasoline. Look for the
TOP TIER label on the fuel pump to
ensure gasoline meets enhanced
detergency standards developed
by the auto companies. A list of
marketers providing TOP TIER
Detergent Gasoline can be found
at www.toptiergas.com.
For customers who do not use
TOP TIER Detergent Gasoline
regularly, one bottle of GM Fuel
System Treatment PLUS, added
to the fuel tank at every engine oil
change, can help clean deposits
from fuel injectors and intake valves.
GM Fuel System Treatment PLUS
is the only gasoline additive
recommended by General Motors.
It is available at your dealer/retailer.
