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.
SeeTire Pressure Monitor
Operation on page 10-50.
Engine Oil Pressure Light
{Caution
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.
This 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 is near the fuel gauge and
comes on briefly when the ignition is
turned on as a check to show it is
working.
It also comes on when the fuel tank
is low on fuel. The light turns off
when fuel is added. If it does not,
have the vehicle serviced.
Security Light
The security 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
system is working normally, the
indicator light turns off.

Move the slats (2) to change the
direction of the airflow.
Additional air vents are beneath the
windshield and the driver side and
passenger side door windows.
These are fixed and cannot be
adjusted.Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
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.
Check with your dealer before
adding equipment to the outside
of the vehicle.
.Do not attach any devices to the
air vent slats. This restricts
airflow and may cause damage
to the air vents.
Maintenance
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
See
Maintenance Schedule on
page 11-3.
See your dealer regarding
replacement of the filter.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained
and certified technicians. The air
conditioning evaporator should
never be repaired or replaced by
one from a salvage vehicle.
It should only be replaced by a new
evaporator to ensure proper and
safe operation.

9-4 Driving and Operating
If the engine ever stops while the
vehicle is being driven, brake
normally but do not pump the
brakes. Doing so could make the
pedal harder to push down. 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
Variable Effort Steering
Some vehicles have a steering
system that varies the amount of
effort required to steer the vehicle in
relation to the speed of the vehicle.
The amount of steering effort
required is less at slower speeds to
make the vehicle more
maneuverable and easier to park. At
faster speeds, the steering effort
increases to provide a sport-like feel
to the steering. This provides
maximum control and stability.If the vehicle seems harder to steer
than normal when parking or driving
slowly, there may be a problem with
the system. You will still have power
steering, but steering will be stiffer
than normal at slow speeds. See
your dealer for service.
Electric Power Steering
The 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. See your dealer if
there is a problem.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If steering assist is used for an
extended period of time, power
assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See specific vehicle steering
messages under
Vehicle Messages
on page 5-32.
See your dealer if there is a
problem.Curve Tips
.Take curves at a reasonable
speed.
.Reduce speed before entering a
curve.
.Maintain a reasonable steady
speed through the curve.
.Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.

Driving and Operating 9-37
Snow/Ice Mode
Use when more traction is needed
during slippery conditions. The
transmission will use 2 (Second)
gear instead of 1 (First) gear when
accelerating from a stop. The
vehicle will upshift normally when
the vehicle is moving.
When selected, the Snow/Ice mode
indicator will display in the DIC.
This feature is not intended for use
when the vehicle is stuck in sand,
mud, ice, snow or gravel. If the
vehicle becomes stuck, seeIf the
Vehicle Is Stuck on page 9-11.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axle
can give more traction on snow,
mud, ice, sand, or gravel. When
traction is low, this feature allows
the drive wheel with the most
traction to move the vehicle. The
limited-slip rear axle also gives the
driver enhanced control when
cornering hard or completing a
maneuver, such as a lane change.
Limited-slip rear axle fluid should be
changed at intervals listed in
Maintenance Schedule on
page 11-3.
Cruise Control
{Warning
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. 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.
With cruise control, a speed of
about 40 km/h (25 mph) or more can
be maintained without keeping your
foot on the accelerator. Cruise
control does not work at speeds
below about 40 km/h (25 mph).
If the brakes are applied, the cruise
control disengages.

9-62 Driving and Operating
Fuel
Use of the recommended fuel is an
important part of the proper
maintenance of this vehicle. When
driving in the U.S., to help keep the
engine clean and maintain optimum
vehicle performance, we
recommend using TOP TIER
Detergent Gasolines. See
www.toptiergas.com for a list of TOP
TIER Detergent Gasolines.
If the vehicle has a yellow fuel cap,
E85 or FlexFuel can be used in the
vehicle. SeeE85 or FlexFuel on
page 9-64.
Recommended Fuel
If the vehicle has a 2.5L L4 engine
or a 3.6L V6 engine, 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.
If the vehicle has the 2.0L L4
engine, use premium unleaded
gasoline with a posted octane rating
of 91 or higher. You can also use
regular unleaded gasoline rated at
87 octane or higher, but the
vehicle's acceleration could be
slightly reduced, and a slight audible knocking noise, commonly referred
to as spark knock, might be heard.
If the octane is less than 87, a
heavy knocking noise might be
heard when driving. If this occurs,
use a gasoline rated at 87 octane or
higher as soon as possible.
Otherwise, you could damage the
engine. If heavy knocking is heard
when using gasoline rated at
87 octane or higher, the engine
needs service.
Use of Seasonal Fuels
Use summer and winter fuels in the
appropriate season. Driving or
starting could be affected if the
incorrect fuel is used. Drive the
vehicle with the engine running until
the fuel is a half tank or less, then
refuel with the current seasonal fuel.
Prohibited Fuels
Gasolines containing oxygenates,
such as ethers and ethanol, as well
as reformulated gasolines are
available in some cities. If these
gasolines comply with the
previously described specification,
