106 Instruments and Controls
Boost Gauge
Metric
English
This gauge indicates vacuum during
light to moderate throttle and boost
under heavier throttle.
It displays the air pressure level in
the intake manifold before it enters
the engine's combustion chamber.
The gauge is automatically centered
at zero every time the engine is
started. Actual vacuum or boost is
displayed from this zero point.
Changes in ambient pressure, such
as driving in mountains and
changing weather, will slightly
change the zero reading.
Engine Coolant
Temperature Gauge
Metric

Instruments and Controls 107
English
This gauge shows the engine
coolant temperature.
If the gauge pointer moves to the
high end, the engine is too hot.
This reading indicates the same
thing as the warning light. It means
that the engine coolant has
overheated. If the vehicle has been
operating under normal driving
conditions, pull off the road, stop the
vehicle, and turn off the engine as
soon as possible. See Engine
Overheating 0236 for more
information.
Seat Belt Reminders
Driver Seat Belt Reminder
Light
There is a driver seat belt reminder
light on the instrument cluster.
When the vehicle is started, this
light flashes and a chime may come
on to remind the driver to fasten
their seat belt. Then the light stays
on solid until the belt is buckled.
This cycle may continue several
times if the driver remains or
becomes unbuckled while the
vehicle is moving.
If the driver seat belt is buckled,
neither the light nor chime
comes on.
Passenger Seat Belt Reminder
Light
There is a passenger seat belt
reminder light on the instrument
cluster.
When the vehicle is started this light
flashes and a chime may come on
to remind passengers to fasten their
seat belt. Then the light stays on
solid until the belt is buckled. This
cycle continues several times if the
passenger remains or becomes
unbuckled while the vehicle is
moving.
If the passenger seat belt is
buckled, neither the chime nor the
light comes on.
The front passenger seat belt
reminder light and chime may turn
on if an object is put on the seat
such as a briefcase, handbag,
grocery bag, laptop or other

If the ESC and TCS are off, the
system does not assist in controlling
the vehicle. Turn on the TCS and
the ESC systems and the warning
light turns off.

Engine Coolant
Temperature Warning
Light
This light comes on briefly while
starting the vehicle.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light goes off.
Caution
The engine coolant temperature
warning light indicates that the
vehicle has overheated. Driving
with this light on can damage the
engine and it may not be covered
by the vehicle warranty. See
Engine Overheating 0236.
The engine coolant temperature
warning light comes on when the
engine has overheated.
If this happens, pull over and turn
off the engine as soon as possible.
See Engine Overheating 0236.
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the engine is
started. It provides information
about tire pressures and the TPMS.
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. Stop as soon as possible,
and inflate the tires to the pressure
value shown on the Tire and
Loading Information label. See Tire
Pressure 0263.
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 0265.

Climate Controls 151
Air Vents
Use the tab on the air outlets to
change the direction of the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into the
vehicle.
. Clear snow off the hood to
improve visibility and help
decrease moisture drawn into
the vehicle.
. Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
. Keep the area around the base
of the instrument panel console
and air path under the seats
clear of objects to help circulate
the air inside of the vehicle more
effectively.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter reduces dust, pollen, and other
airborne irritants from outside air
that is pulled into the vehicle.
Reductions in airflow, which may
occur more often in dusty areas,
indicate that the filter may need to
be replaced. See Maintenance
Schedule 0299.
Caution
Driving without a passenger
compartment air filter in place can
cause water and small particles,
like paper and leaves, to be
pulled into your climate control
system which may cause damage
to it. Make sure you always
replace the old filter with a
new one. The passenger compartment air
filter is on the passenger side of the
engine compartment near the
coolant surge tank. See
Engine
Compartment Overview 0217.
To check or replace the air filter:
1. Release the retainer clips from the passenger compartment air
filter cover. The PVC hoses
may need to be held out of the
way briefly to access the air
filter cover.
2. Remove the cover.

160 Driving and Operating
competitive driving. See
Recommended Fluids and
Lubricants0308.
General Information
If reduced performance is
experienced during track events or
competitive driving, turning off the
A/C will help to improve engine
performance.
Maintain a mixture of 40%
DEX-COOL coolant and 60% clean,
drinkable water to optimize engine
performance.
The front license plate bracket or
aero panel should be removed for
track events and competitive driving
to improve engine performance.
If additional brake cooling is
required, the grille mesh in the lower
corners of the front grille in front of
the brake duct can be removed.
This is not reversible, and a
replacement grille will not be
covered by the vehicle warranty.
If this is done, it is recommended
that the gap between the fascia and
the cooling duct be taped over.Brake Burnishing
New brake pads must be burnished
before racing or other competitive
driving.
Caution
Performing the brake burnish
procedure on a base brake
system can result in brake
damage.
Caution
The new vehicle break-in period
should be completed before
performing the brake burnish
procedure, otherwise damage
may occur to the powertrain/
engine. See New Vehicle
Break-In 0174.
Caution
Brake pedal fade will occur during
any track burnish procedure and
can cause brake pedal travel and
force to increase. This could
extend stopping distance until the
brakes are fully burnished.
When this procedure is performed
as instructed, it will not damage the
brakes. The brake pads will smoke
and produce an odor. The braking
force and pedal travel may increase.
After the procedure, the brake pads
may appear white at the rotor
contact.
Perform this procedure only on dry
pavement, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor
vehicle operation.
