106 INSTRUMENTS AND CONTROLS
If, after several seconds, all of the
symbols remain lit, or if no symbols
are lit, or if the airbag readiness light
is on, there may be a problem with
the lights or the passenger sensing
system. See your dealer for service
right away.
{Warning
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong with
the airbag system. To help avoid
injury to yourself or others, have
the vehicle serviced right away. See
Airbag Readiness Light0105 for
more information, including
important safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned on,
but the engine is not running, as a
check to show the light is working.
It should go out when the engine is
started.
If the light 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.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a message.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio and
air conditioner. Find a safe place to
stop the vehicle.
Malfunction Indicator Lamp
(Check Engine Light)
This light is part of the vehicle’s
emission control on-board diagnostic
system. If this light is on while the
engine is running, a malfunction has
been detected and the vehicle may require service. The light should come
on to show that it is working when
the ignition is in Service Mode. See
Ignition Positions
0238.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when it
comes on may prevent damage.
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not run
smoothly. This could lead to costly
repairs that might not be covered
by the vehicle warranty.

INSTRUMENTS AND CONTROLS 107
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not meet
the original tire specifications, can
cause this light to come on. This
could lead to costly repairs not
covered by the vehicle warranty.
This could also affect the vehicle’s
ability to pass an Emissions
Inspection/Maintenance test. See
Accessories and Modifications0328.
If the light is f lashing : A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service may
be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the amount
of cargo being hauled as soon as
possible. If the light continues to flash, find a
safe place to park. Turn the vehicle off
and wait at least 10 seconds before
restarting the engine. If the light is
still flashing, follow the previous
guidelines and see your dealer for
service as soon as possible.
If the light is on steady :
A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
.If fuel has been added to the vehicle
using the capless fuel funnel
adapter, make sure that it has been
removed. See “Filling the Tank with
a Portable Gas Can ”under Filling the
Tank 0317. The diagnostic system
can detect if the adapter has been
left installed in the vehicle, allowing
fuel to evaporate into the
atmosphere. A few driving trips with
the adapter removed may turn off
the light.
.Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed up.
If this occurs, change the fuel brand. It may require at least one
full tank of the proper fuel to turn
the light off. See
Recommended Fuel
(LSY 2.0L L4 Engine) 0316 or
Recommended Fuel (LGY 3.0L V6 and
LT4 6.2L V8 Engines) 0316.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the test
equipment will likely connect to the
vehicle's Data Link Connector (DLC).
The DLC is under the instrument
panel to the left of the steering wheel.
Connecting devices that are not used
to perform an Emissions Inspection/
Maintenance test or to service the

vehicle may affect vehicle operation.
SeeAdd-On Electrical Equipment 0326.
See your dealer if assistance is needed.
The vehicle may not pass
inspection if:
.The light is on when the engine is
running.
.The light does not come on when
the ignition is in Service Mode.
.Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if the
12-volt battery has recently been
replaced or run down, or if the
vehicle has been recently serviced.
See your dealer if the vehicle will not
pass or cannot be made ready for
the test.
Brake System Warning
Light
MetricEnglish
This light should come on briefly
when the vehicle is turned on. If it
does not come on then, have it fixed
so it will be ready to warn you if there
is a problem.
If the light comes on and stays on at
start up, there is a brake problem.
Have the brake system inspected
right away.
If the light comes on while driving,
pull off the road and stop carefully.
The brake system has electric brake
boost. Vehicle speed may be limited
when the brake system warning light
comes on. The brake pedal might be
harder to push, or the brake pedal
may go closer to the floor. It could take longer to stop. If the light is still
on, have the vehicle towed for service.
See
Towing the Vehicle 0396.
{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 the vehicle has been
pulled off the road and carefully
stopped, have the vehicle towed for
service.
Electric Parking Brake

(TCS)/StabiliTrak Light
This light comes on briefly when the
vehicle is turned on.
If the light does not come on, have
the vehicle serviced by your dealer.
If the system is working normally, the
indicator light turns off.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak/
ESC system are not fully operational
and may not assist in maintaining
control. Adjust driving accordingly.
If the condition persists, see your
dealer as soon as possible. A Driver

cluster, this light may not come on
when starting the vehicle.
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 0347. The engine coolant temperature
warning light comes on when the
engine has overheated.

114 INSTRUMENTS AND CONTROLS
Tire Pressure Light
For vehicles with the Tire Pressure
Monitor System (TPMS), this light
comes on briefly when the vehicle 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. SeeTire Pressure 0374.
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
0377.
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
A Low Fuel Warning Light near the
fuel gauge comes on briefly when the
ignition is turned on as a check to
show it is working.
It also comes on when the fuel gauge
indicator nears empty. The light turns
off when fuel is added. If it does not,
have the vehicle serviced.
