StabiliTrak System
The vehicle has the StabiliTrak
system which combines antilock
brake, traction and stability control
systems. This system automatically
controls the brakes and engine to
help prevent the vehicle from
skidding when cornering on a
slippery road surface or turning
the steering wheel abruptly.
This system activates when the
vehicle speed reaches or exceeds
15 km/h (9 mph), and deactivates
when the vehicle speed reduces to
below 15 km/h (9 mph).
A sound may be heard in the engine
compartment for a few seconds
when the engine is started or just
after the vehicle begins to move.
This means that the system is in
the self-check mode, but does not
indicate a problem.If the vehicle is going to skid during
driving, the traction control system
warning light flashes and an alarm
sounds intermittently. Adjust your
driving accordingly.
To turn off both the traction control
system and StabiliTrak, press and
hold
gwhile the vehicle is stopped.
The traction control system warning
light and the VSC OFF light will come
on. To turn the systems back on,
press
gagain. If both systems are
turned off, they will not turn back on
automatically when vehicle speed
increases.
If the VSC OFF light flashes, there
is a problem in the traction control
system or StabiliTrak.
Driving and Operating 8-35

Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this so
the trailer won’t strike soft shoulders,
curbs, road signs, trees or other
objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
flash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also flash, telling
other drivers the vehicle is turning,
changing lanes or stopping. When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. For this reason you may
think other drivers are seeing the
signal when they are not. It is
important to check occasionally to be
sure the trailer bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the transmission
is not shifted down, the brakes
might have to be used so much that
they would get hot and no longer
work well.
Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower gear
if the transmission shifts too often
under heavy loads and/or hilly
conditions. For vehicles with a
manual transmission, it is better
not to use the highest gear.When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at a
lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. For vehicles with manual
transmissions, let the engine run
while parked, preferably on level
ground, with the transmission out of
gear and the parking brake applied,
for a few minutes before turning the
engine off. If the overheat warning
comes on, see
Engine Overheating
on page 9-23.

General Information
For service and parts needs, visit
your dealer/retailer. You will receive
genuine GM parts and GM-trained
and supported service people.
Genuine GM parts have one of
these marks:
California Proposition
65 Warning
Most motor vehicles, including this
one, contain and/or emit chemicals
known to the State of California to
cause cancer and birth defects
or other reproductive harm. Engine
exhaust, many parts and systems
(including some inside the vehicle),
many fluids, and some component
wear by-products contain and/or emit
these chemicals.
9-2 Vehicle Care

What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not 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. Recycle
it by taking it to a place that collects
used oil.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
Check the fluid in the transmission
and differential at the intervals listed
inScheduled Maintenance on
page 10-3, and be sure to use
the transmission fluid listed in
Recommended Fluids and
Lubricants on page 10-15 .
How to Check Automatic
Transmission Fluid
This operation can be difficult, you
may choose to have this done at the
dealer/retailer service department.
If you do it yourself, be sure to
follow all the instructions here,
or you could get a false reading
on the dipstick. Wait at least 30 minutes before
checking the transmission fluid level
if you have been driving:
•When outside temperatures are
above 90°F (32°C).
•At high speed for quite a while.
•In heavy traffic — especially
in hot weather.
•While pulling a trailer.
To get the right reading, the fluid
should be at normal operating
temperature, which is 158°F to
176°F (70°C to 80°C).
Get the vehicle warmed up by
driving about 15 miles (24 km)
when outside temperatures
are above 50°F (10°C). If it is
colder than 50°F (10°C), you
may have to drive longer.
9-12 Vehicle Care

What to Use
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL®
coolant, which will not damage
aluminum parts. If this coolant
mixture is used, nothing else
needs to be added.
{CAUTION
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
The vehicle’s coolant warning
system is set for the proper coolant
mixture. With plain water or the
wrong mixture, the engine could
get too hot but would not get the
overheat warning. The engine
could catch fire and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.Notice:
If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and other
parts.
•Gives freezing protection down to
−34°F (− 38°C).
•Gives boiling protection up to
265°F (129°C).
•Protects against rust and
corrosion.
•Helps keep the proper engine
temperature.
•Lets the warning lights and gages
work as they should.
Notice: Using coolant other than
DEX-COOL can cause premature
engine, heater core or radiator
corrosion. In addition, the engine
coolant may require changing sooner, at 30,000 miles
(50 000 km) or 24 months,
whichever occurs rst. Any
repairs would not be covered
by the vehicle warranty. Always
use DEX-COOL (silicate-free)
coolant in your vehicle.
Checking Coolant
The vehicle must be on a level
surface. When the engine is cold,
the coolant level should be at LOW,
or a little higher. When the engine
is warm, the level should be up to
FULL, or a little higher. If it is not,
there could be a leak at the pressure
cap or in the radiator hoses, heater
hoses, radiator, water pump, or
somewhere else in the cooling
system.
See
Engine Compartment Overview
on page 9-6 for the location of
the coolant recovery tank.
9-20 Vehicle Care

How to Add Coolant to the
Coolant Recovery Tank
If you need more coolant, add the
proper DEX-COOL®coolant mixture
at the coolant recovery tank, but
be careful not to spill it.
Occasionally check the coolant level
in the radiator. For information on
how to add coolant to the radiator,
see Cooling System on page 9-19 .
{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. Do not spill
coolant on a hot engine.
{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.
(Continued)
CAUTION (Continued)
Your vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, your engine
could get too hot but you would
not get the overheat warning.
Your engine could catch fire and
you or others could be burned.
Use a 50/50 mixture of clean,
drinkable water and a proper
coolant.
Notice: In cold weather, water
can freeze and crack the engine,
radiator, heater core and other
parts. Use the recommended
coolant and the proper coolant
mixture.
Vehicle Care 9-21

How to Add Coolant to the
Radiator
When the coolant in the coolant
recovery tank is at the FULL mark,
start the vehicle.
If the overheat warning continues,
there is one more thing that can
be done. Add the proper coolant
mixture directly to the radiator but
be sure the cooling system is
cool before you do it.
{CAUTION
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn the
surge tank pressure cap — even a
little — they can come out at high
speed. Never turn the cap when
the cooling system, including the
surge tank pressure cap, is hot.
Wait for the cooling system and(Continued)
CAUTION (Continued)
surge tank pressure cap to cool
if you ever have to turn the
pressure cap.
{CAUTION
Turning the radiator pressure cap
when the engine and radiator are
hot can allow steam and scalding
liquids to blow out and burn you
badly. With the coolant recovery
tank, you will almost never have
to add coolant at the radiator.
Never turn the radiator pressure
cap — even a little — when the
engine and radiator are hot.
1. Remove the pressure cap when the cooling system, including the
pressure cap and upper radiator
hose, is no longer hot. Turn
the pressure cap slowly
counterclockwise until it first
stops. Do not press down while
turning the pressure cap. If you hear a hiss, wait for that to
stop. A hiss means there is
still some pressure left.
2. Keep turning the pressure cap, but now push down while turning.
Remove the pressure cap.
3. Fill the radiator with the proper coolant mixture, up to the base
of the filler neck. For more
information about the proper
coolant mixture look earlier in
this section.
4. Then fill the coolant recovery tank to the FULL mark.
