.Check that good quality fuel is
used. Poor fuel quality causes
the engine not to run as
efficiently as designed and may
cause stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand used.
It will require at least one full tank of
the proper fuel to turn the light off.
See Recommended Fuel on
page 9‑41.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.Emissions Inspection and
Maintenance Programs
Some local governments may
have programs to inspect the
on-vehicle emission control
equipment. For the inspection, the
emission system test equipment
is connected to the vehicle’s Data
Link Connector (DLC).
The DLC is under the instrument
panel next to the steering wheel.
See your dealer if assistance is
needed.
The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on while the vehicle is running.
The vehicle is in ON/RUN for
keyed access, or service only mode for keyless access and the
malfunction indicator lamp does
not come on. See your dealer for
assistance in verifying proper
operation of the malfunction
indicator lamp.
.The OBD II (On-Board
Diagnostics) system determines
that critical emission control
systems have not been
completely diagnosed. The
vehicle would be considered not
ready for inspection. This can
happen if the 12-volt battery has
recently been replaced or run
down. The diagnostic system is
designed to evaluate critical
emission control systems during
normal driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the
inspection for lack of OBD II
system readiness, your dealer
can prepare the vehicle for
inspection.

When the Light Is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. SeeTire Messages on
page 5‑29. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the Tire
and Loading Information label. See
Tire Pressure on page 10‑42.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition
cycle. See Tire Pressure Monitor
Operation on page 10‑44.Engine Oil Pressure Light
Notice: Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine
oil low can also damage the
engine. The repairs would not be
covered by the vehicle warranty.
Check the oil level as soon as
possible. Add oil if required,
but if the oil level is within the
operating range and the oil
pressure is still low, have the
vehicle serviced. Always follow
the maintenance schedule for
changing engine oil.
The oil pressure light should come
on briefly as the engine is started.
If it does not come on, have the
vehicle serviced by your dealer. If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.
Low Fuel Warning Light
This light comes on for a few
seconds when the ignition is
turned on as a check to indicate it
is working. If it does not come on,
have it fixed.

Remaining Oil Life
This display shows an estimate
of the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON
message will appear on the display.
See Engine Oil Messages on
page 5‑27. The oil should be
changed as soon as possible.
See Engine Oil on page 10‑7. In addition to the Engine Oil Life
System monitoring the oil life,
additional maintenance is
recommended in the Maintenance
Schedule in this manual. See
Maintenance Schedule on
page 11‑3
for more information.
Remember, the Remaining Oil Life
display must be reset after each
oil change. It will not reset itself.
Also, be careful not to reset
the Remaining Oil Life display
accidentally at any time other than
when the oil has just been changed.
It cannot be reset accurately until
the next oil change. To reset the
Engine Oil Life System, press
SET/CLR while the Remaining Oil
Life display is active. See Engine

8-6 Climate Controls
Sensors
The solar sensor, located on top
of the instrument panel near the
windshield, monitors the solar heat.
The climate control system uses
the sensor information to adjust
the temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
If the sensor is covered, the
automatic climate control system
may not work properly.
Air Vents
Use the louvers located on the air
vents to change the direction of the
airflow.
Use the thumbwheels near the air
vents to control the amount of
airflow or to shut off the airflow.
Operation Tips
.Keep all outlets open whenever
possible for best system
performance.
.Keep the paths under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Maintenance
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
SeeMaintenance Schedule on
page 11‑3.
See your dealer regarding
replacement of the filter.

9-4 Driving and Operating
If the engine stops, there will be
some power brake assist but it will
be used when the brake is applied.
Once the power assist is used up, it
can take longer to stop and the
brake pedal will be harder to push.
Steering
Electric Power Steering
Your vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
If the steering wheel is turned in
either direction several times until
it stops, or it is held until it is
stopped for an extended time,
power steering assist should return
shortly after a few normal steering
movements.See specific vehicle steering
messages under
Vehicle Messages
on page 5‑25.
See your dealer if there is a
problem.
Curve Tips
.Take curves at a reasonable
speed.
.Reduce speed before entering a
curve, while the front wheels are
straight.
.Adjust speed so you can drive
through the curve. Maintain a
reasonable, steady speed.
.Wait until out of the curve before
accelerating gently into the
straightaway.
Steering in Emergencies
There are times when steering
can be more effective than braking.
For example, you come over a hill
and find a truck stopped in the lane,
or a child darts out from between
parked cars and stops right in front
of you. These problems can be
avoided by braking —if you can
stop in time.
If you cannot fully stop, follow these
suggestions:
.Quickly apply the brakes to
remove as much speed as
possible from a collision.
.Steer around the problem, to
the left or right depending on
available space.
.Straighten the wheel once you
have avoided the object.

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.
The eighth digit of the Vehicle
Identification Number (VIN) shows
the code letter or number that
identifies the vehicle's engine.
The VIN is at the top left of the
instrument panel. SeeVehicle
Identification Number (VIN) on
page 12‑1.
Vehicles that have a FlexFuel badge
and a yellow fuel cap can use either
unleaded gasoline or ethanol fuel
containing up to 85% ethanol (E85). See
Fuel E85 (85% Ethanol) on
page 9‑43. For all other vehicles,
use only the unleaded gasoline
described under Recommended
Fuel on page 9‑41.
Recommended Fuel
Use regular unleaded gasoline with
a posted octane rating of 87 or
higher. If the octane rating is less
than 87, an audible knocking noise,
commonly referred to as spark
knock, might be heard when driving.
If this occurs, use a gasoline rated
at 87 octane or higher as soon as
possible. If heavy knocking is heard
when using gasoline rated at
87 octane or higher, the engine
needs service.
