However, you should turn StabiliTrak
off if your vehicle gets stuck in sand,
mud, ice, or snow and you want to
rock your vehicle to attempt to free it,or if you are driving in extreme
off-road conditions and require more
wheel spin. SeeIf Your Vehicle is

TIGHTEN GAS CAP
This message may display along
with the check engine light on the
instrument panel cluster if the
vehicle’s fuel cap is not tightened
properly. SeeMalfunction Indicator
Lamp on page 3-35. Reinstall the
fuel cap fully. SeeFilling the Tank
on page 5-8. The diagnostic system
can determine if the fuel cap has
been left off or improperly installed.
A loose or missing fuel cap allows
fuel to evaporate into the
atmosphere. A few driving trips
with the cap properly installed should
turn this light and message off.
Instrument Panel 3-55

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 speci cation 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. SeeAdditives on
page 5-6for additional information.
California Fuel
If the vehicle is certi ed to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California speci cations. 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
speci cations, 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 3-35. 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.
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.
5-6 Service and Appearance Care
ProCarManuals.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.
Also, your dealer/retailer has
additives that will help correct and
prevent most deposit-related
problems.
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
speci cations 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.
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.

To remove the fuel cap, turn it slowly
counterclockwise. The fuel cap has a
spring in it; if the cap is released too
soon, it will spring back to the right.
To avoid fuel contact on the painted
surface of the vehicle when lling the
fuel tank, place the tethered cap on
the fuel ller door.
{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 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 5-75.
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. SeeMalfunction
Indicator Lamp on page 3-35.
{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/retailer can get one for
you. If you get the wrong type, it
might not t properly. This can
cause the malfunction indicator
lamp to light and can damage the
fuel tank and emissions system.
