air ow. Use the vertical thumbwheel
next to the outlets to control the
amount of air ow or to shut off the
airow completely.
Keep all outlets open whenever
possible for best system
performance.
Operation Tips

Clear away any ice, snow, or
leaves from the air inlets at
the base of the windshield that
can block the ow of air into
the vehicle.
Use of non-GM approved hood
deectors can adversely affect
the performance of the system.
Keep the path under all seats

Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of your vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Gasoline Octane
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 assoon as possible. If you are using
gasoline rated at 87 octane or higher
and you hear heavy knocking, the
engine needs service.
Gasoline Specications
At a minimum, gasoline should
meet ASTM specication
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 8-36for additional information.
California Fuel
If your vehicle is certied to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specications. See
the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, your vehicle will operate
satisfactorily on fuels meeting federal
specications, but emission control
system performance might be
affected. The malfunction indicator
lamp could turn on and your vehicle
might fail a smog-check test. See
Malfunction Indicator Lamp on
page 4-20. 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.

Headlamp Aiming
The optical headlamp aiming system
has been preset at the factory
and should need no further
adjustment.
However, If the vehicle is damaged
in a crash, the headlamp aim
may be affected and adjustment
may be necessary.
If oncoming vehicles ash their high
beams at you, this may also mean
the vertical aim needs to be adjusted.
It is recommended that the vehicle
is taken to your dealer/retailer for
service if the headlamps need to be
re-aimed. It is possible however, to
re-aim the headlamps as described.The vehicle should:Be placed so the headlamps
are 25 ft. (7.6 m) from a light
colored wall.
Have all four tires on a perfectly
level surface which is level all
the way to the wall.
Be placed so it is perpendicular
to the wall.
Not have any snow, ice, or
mudonit.
Be fully assembled and all other
work stopped while headlamp
aiming is being done.
Have a full tank of fuel and
one person or 160 lbs (75 kg)
on the driver seat.
Have all tires properly inated.Headlamp aiming is done with the
vehicle’s low-beam headlamps.
The high-beam headlamps will be
correctly aimed if the low-beam
headlamps are aimed properly.
To adjust the vertical aim on
the headlamps:
1. Open the hood. SeeHood
Release on page 9-5for more
information.
2. Locate the aim dot on the lens of
