Warning Lights,
Gauges, and
Indicators
Warning lights and gauges can
signal that something is wrong
before it becomes serious enough
to cause an expensive repair or
replacement. Paying attention to the
warning lights and gauges could
prevent injury.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.

.Passenger seat unoccupied: The
passenger airbag status
indicator lights to indicate that
the front passenger frontal
airbag is off and will not inflate in
a collision.
See Passenger Sensing System
0 56 for more information.
Charging System Light
This light will come on briefly when
the ignition is turned on, and the
engine is not running, as a check to
show it is working.
It should go out when the engine is
started. If it stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery. If a short
distance must be driven with the light on, turn off all accessories,
such as the radio and air
conditioner, to help reduce the drain
on the battery.
Malfunction Indicator
Lamp (Check Engine
Light)
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors the operation
of the vehicle to ensure emissions
are at acceptable levels, helping to
maintain a clean environment. The
malfunction indicator lamp comes
on when the vehicle is placed in
ON, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer. See
Ignition Positions
0145 for more
information.
If the malfunction indicator lamp
comes on while the engine is
running, this indicates that the
OBD II system has detected a
problem and diagnosis and service
might be required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system also
assists the service technician in
correctly diagnosing any
malfunction.
Caution
If the vehicle is continually driven
with this light on, the emission
controls might not work as well,
the vehicle fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.

92 Instruments and Controls
Caution
Modifications made to the engine,
transmission, exhaust, intake,
or fuel system of the vehicle or
the replacement of the original
tires with other than those of the
same size and type as the
originals can affect the vehicle's
emission controls and can cause
this light to come on.
Modifications to these systems
could lead to costly repairs not
covered by the vehicle warranty.
This could also result in a failure
to pass a required Emission
Inspection/Maintenance test. See
Accessories and Modifications
0178.
This light comes on during a
malfunction in one of two ways:
Light Flashing : A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required. To prevent more serious damage to
the vehicle:
.
Do not drive at speeds above
72 km/h (45 mph)
. Avoid hard accelerations.
. Avoid steep uphill grades.
If the light continues to flash, find a
safe place to stop and park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible.
Light On Steady : An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
The following may correct an
emission control system
malfunction:
. Check that the fuel cap is fully
installed. See Filling the Tank
0 172. 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 the light off.
. 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 may require at least one full tank
of the proper fuel to turn the light off.
See Fuel 0170.
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.

When the ignition is on, the brake
system warning light also comes on
when the parking brake is set. See
Parking Brake0156. The light stays
on if the parking brake does not fully
release. If it stays on after the
parking brake is fully released, it
means the vehicle has a brake
problem.
If the light comes on while driving,
pull off the road and stop carefully.
The pedal might be harder to push,
or the pedal might go closer to the
floor. It could take longer to stop.
If the light is still on, check the brake
fluid level and have the vehicle
towed for service. See Towing the
Vehicle 0231.
{Warning
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
(Continued)

the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Antilock Brake System
(ABS) Warning Light
MetricEnglish
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes.
If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light

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
The low fuel warning light may
come on when the fuel tank is low
on fuel. When fuel is added, the
light should go off. If it does not,
have the vehicle serviced.

154 Driving and Operating
Each time the engine is started,
or when the shift lever is shifted to
any position other than D (Drive),
the Overdrive off mode will be
automatically turned off.
Accelerator Downshift in D
Position
For passing or hill climbing, press
the accelerator pedal to the floor.
This shifts the transmission down
into a lower gear, depending on the
vehicle speed.
High Fluid Temperature
Protection Mode
If the fluid temperature becomes too
high from climbing a steep grade in
high temperatures, such as towing a
trailer. Engine power and vehicle
speed will be decreased
automatically to reduce the chance
of transmission damage. Vehicle
speed can be controlled with the
accelerator pedal but the engine
and vehicle speed may be limited.Fail Safe
When the fail-safe operation occurs,
the CVT will not be shifted into the
selected driving position.
If the vehicle is driven under
extreme conditions, such as
excessive wheel spinning and
subsequent hard braking, the
fail-safe system may be activated.
The malfunction indicator lamp may
come on to indicate the fail-safe
mode is activated. See
Malfunction
Indicator Lamp (Check Engine
Light) 091. This will occur even if all
electrical circuits are functioning
properly. In this case, place the
ignition switch in the OFF position
and wait for 10 seconds. Then place
the ignition switch back in the ON
position. The vehicle should return
to its normal operating condition. If it
does not return to its normal
operating condition, have a dealer
check the transmission and repair if
necessary.
{Warning
When the high fluid temperature
protection mode or fail-safe
operation occurs, vehicle speed
may be gradually reduced. The
reduced speed may be lower than
other traffic, which could increase
the chance of a collision. Be
especially careful when driving.
If necessary, pull to the side of
the road at a safe place and allow
the transmission to return to
normal operation, or have it
repaired if necessary.

Driving and Operating 171
Warning (Continued)
.Under no circumstances
should either a leaded
gasoline or gasoline with
MMTbe used. Doing so will
damage the catalytic
converter.
. Do not use E85 fuel in your
vehicle. Your vehicle is not
designed to run on E85 fuel.
Using E85 fuel in a vehicle
not specifically designed for
E85 fuel can adversely
damage the emission
control devices and systems
of the vehicle. Damage
caused by such fuel is not
covered by the new vehicle
limited warranty.
Some gasolines, mainly high octane
racing gasolines, can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). Do not use
gasolines and/or fuel additives with
MMT as they will reduce spark plug
life and affect emission control system. The malfunction indicator
lamp may turn on. If this occurs, see
your dealer for service.
California Fuel
Requirements
If the vehicle is certified to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specifications. 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 specifications, but emission
control system performance may be
affected. The malfunction indicator
lamp could turn on and the vehicle
may not pass a smog-check test.
See
Malfunction Indicator Lamp
(Check Engine Light) 091. If this
occurs, return to your authorized
dealer for diagnosis. If it is
determined that the condition is
caused by the type of fuel used,
repairs may not be covered by the
vehicle warranty.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico post
fuel octane ratings in anti-knock
index (AKI). For fuel not to use in a
foreign country, see “Prohibited
Fuels” inFuel 0170.
Fuel Additives
To keep fuel systems clean, TOP
TIER detergent gasoline is
recommended. See Fuel0170.
If TOP TIER detergent gasoline is
not available, one bottle of GM Fuel
System Treatment Cleaner added to
the fuel tank at every engine oil
change, can help. GM Fuel System
Treatment Cleaner is the only
gasoline additive recommended by
General Motors. It is available at
your dealer.
