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.

Cruise Control
For vehicles with cruise control, the
lever is located on the right side
of the steering wheel.Cruise control, lets a speed of
25 mph (40 km/h) or more be
maintained without keeping your foot
on the accelerator. Cruise control
does not work at speeds below
25 mph (40 km/h).
{CAUTION
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.Setting Cruise Control
{CAUTION
If you leave your cruise control on
when you are not using cruise,
you might hit a button and go into
cruise when you do not want to.
You could be startled and even
lose control. Keep the cruise
control switch off until you want to
use cruise control.
1. Press the ON-OFF button at the end of the lever. The CRUISE
light on the instrument panel
cluster comes on. See Cruise
Control Light on page 4-21 .
2. Get to the desired speed.
3. Move the lever down to −SET
and release it.
4. Take your foot off the accelerator pedal.

Page 171 of 318

If the cruise control indicator light
flashes, press the ON-OFF button
once to deactivate the system,
and then press the button back on.
If the cruise control speed cannot
be set or the cruise control cancels
immediately after being activated,
there may be a problem with the
cruise control system. See your
dealer/retailer.
Resuming a Set Speed
If the brakes are applied after the
cruise control is set, the cruise
control is turned off.
If the vehicle speed is 25 mph
(40 km/h) or greater, push the lever
up to +RES (Resume/Accelerate) to
return to the previously set speed.Increasing Speed While Using
Cruise Control
There are three ways to increase
the vehicle speed:
•Use the accelerator pedal to get
to the higher speed. Move the
lever down to
−SET. Release the
lever and the accelerator pedal.
•Move the cruise lever up to +RES.
Hold it there until the desired
speed is reached, and then
release the lever.
•To increase the vehicle speed in
very small amounts, move the
lever to +RES briefly and then
release it. Each time this is done,
the vehicle goes about 1 mph
(1.6 km/h) faster. Reducing Speed While Using
Cruise Control
There are two ways to reduce the
vehicle speed while using cruise
control:
•Push and hold the lever to
−SET
until the desired lower speed is
reached, then release it.
•To slow down in very small
amounts, push the lever down
briefly. Each time this is done,
the vehicle will go about 1 mph
(1.6 km/h) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the cruise
control speed set earlier.

Using Cruise Control on Hills
The cruise control performance will
vary depending upon the vehicle
speed, load, and the steepness of
the hills.
When going up steep hills, you might
have to step on the accelerator pedal
to maintain the vehicle speed.
When going downhill, you might
have to brake or shift to a lower gear
to keep the vehicle speed down.
Applying the brake or downshifting
to 2 SECOND or L LOW turns
off the cruise control.Ending Cruise Control
There are several ways to turn off
the cruise control:
•Step on the brake pedal or push
the clutch pedal, if the vehicle
has a manual transmission.
•Press the ON-OFF button.
•Pull the cruise control lever
toward you.
Erasing Speed Memory
The cruise control set speed memory
is erased when the cruise control or
the ignition is turned off.
Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
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 auto companies. A list
of marketers providing TOP TIER
Detergent Gasoline can be found at
www.toptiergas.com.
8-38 Driving and Operating
Page 173 of 318

Recommended Fuel
Use regular unleaded gasoline with a
posted octane rating of 87 or higher.
If the octane rating is less than 87,
you might notice an audible knocking
noise when you drive, commonly
referred to as spark knock. If this
occurs, use a gasoline rated at
87 octane or higher as soon as
possible. If you are using gasoline
rated at 87 octane or higher and you
hear heavy knocking, the engine
needs service.
Gasoline Speci cations
At a minimum, gasoline should
meet ASTM specification D 4814
in the United States or CAN/
CGSB-3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeFuel Additives
on page 8-40 for additional
information.
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.
See Malfunction Indicator Lamp on
page 4-14. 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.
Driving and Operating 8-39

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 the
minimum 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.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might be
available in your area. We
recommend that you use these
gasolines, if they comply with the
specifications described earlier.
However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.
8-40 Driving and Operating

Notice:This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy gasoline whether the
fuel contains MMT. We recommend
against the use of such gasolines.
Fuels containing MMT can reduce
the life of spark plugs and the
performance of the emission
control system could be affected.
The malfunction indicator lamp might
turn on. If this occurs, return to your
dealer/retailer for service.Filling the Tank
{CAUTION
Fuel vapor burns violently and a
fuel fire can cause bad injuries.
To help avoid injuries to you and
others, read and follow all the
instructions on the pump island.
Turn off the engine when you are
refueling. Do not smoke if you are
near fuel or refueling the vehicle.
Do not use cellular phones. Keep
sparks, flames, and smoking
materials away from fuel. Do not
leave the fuel pump unattended
when refueling the vehicle. This is
against the law in some places.
Do not re-enter the vehicle while
pumping fuel. Keep children away
from the fuel pump; never let
children pump fuel. The fuel door release lever is near
the floor under the driver seat on the
outboard side.
Driving and Operating 8-41

The tethered fuel cap is located
behind a hinged fuel door on
the driver side of the vehicle.
To remove the fuel cap, turn it slowly
counterclockwise. On some vehicles
you may have to push in while
turning the cap.
While refueling, hang the fuel cap
inside of the fuel door.
When reinstalling the cap, turn it
clockwise until it clicks, otherwise
the Malfunction Indicator Lamp may
turn on. SeeMalfunction Indicator
Lamp on page 4-14.
{CAUTION
Fuel can spray out on you if
you open the fuel cap too quickly.
If you spill fuel and then something
ignites it, you could be badly
burned. This spray can happen if
the 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 overfill the tank and wait a
few seconds after you have finished
pumping before removing the nozzle.
Clean fuel from painted surfaces as
soon as possible. See Exterior Care
on page 9-75.
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.
See
Malfunction Indicator Lamp
on page 4-14.
{CAUTION
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow 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/retailer can get one for
you. If you get the wrong type, it
may not t properly. This may
cause the malfunction indicator
lamp to light and may damage the
fuel tank and emissions system.
