Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments have or might begin
programs to inspect the emission
control equipment on the vehicle.
Failure to pass this inspection
could prevent getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
.The vehicle will not pass this
inspection if the check engine
light is on with the engine
running, or if the key is in
ON/RUN and the light is not on.
.The vehicle will not pass
this inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not been
completely diagnosed by the
system. The vehicle would
be considered not ready for
inspection. This can happen ifthe battery has recently been
replaced or if the battery has 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.
Brake System Warning
Light
The vehicle's hydraulic brake
system is divided into two parts.
If one part is not working, the other
part can still work and stop the
vehicle. For good braking though,
both parts need to be working well.
If the warning light comes on, there
could be a brake problem. Have the
brake system inspected right away.
United StatesCanada
This light comes on briefly when the
ignition key is turned to ON/RUN.
If it does not, have it fixed so it will
be ready to warn if there is a
problem.
When the ignition is on, the brake
system warning light comes on
when the parking brake is set.
See Parking Brake
on page 9‑51for more information. The light stays
on if the parking brake does not
release fully. If it stays on after the
parking brake is fully released, it
means there is a brake problem.

Instruments and Controls 5-15
If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or it
might go closer to the floor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing the Vehicle
on
page 10‑90.
{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.
Antilock Brake System
(ABS) Warning Light
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 will then go 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
on page 5‑14.
For vehicles with a Driver
Information Center (DIC), see
Brake System Messages
on
page 5‑22for more information.
Up-Shift Light
The vehicle may have an up-shift
light.
When this light comes on, shift to
the next higher gear if weather,
road, and traffic conditions allow.
See Manual Transmission
on
page 9‑44for more information.

5-16 Instruments and Controls
Traction Control System
(TCS)/StabiliTrak®Light
The StabiliTrak system or the
Traction Control System (TCS)
indicator/warning light comes on
briefly while starting the engine.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light will then go off.
The indicator/warning light flashes
while the StabiliTrak or TCS system
is working to control the vehicle on
a low traction surface.
If the TCS warning light comes on
and stays on while driving, the
vehicle needs service.The light comes on when the TCS
and the StabiliTrak system is turned
off. If the TCS is off, wheel spin is
not limited. If the StabiliTrak system
is off, the system does not assist in
controlling the vehicle. Turn on the
TCS and the StabiliTrak system and
the warning light turns off.
See
StabiliTrak System
on
page 9‑53and Traction Control
System (TCS)on page 9‑52for
more information
Tire Pressure Light
For vehicles with a tire pressure
monitoring system, this light comes
on briefly when the engine is
started. It provides information
about tire pressures and the Tire
Pressure Monitoring System. When the Light is On Steady
This indicates that one or more
of the tires are significantly
underinflated.
A tire pressure message in the
Driver Information Center (DIC),
can accompany the light. See
Tire
Messages
on page 5‑25for
more information. Stop as soon as
possible, and inflate the tires to the
pressure value shown on the tire
loading information label. See Tire
Pressure
on page 10‑51for more
information.
When the Light Flashes First and
Then is On Steady
This indicates that there may be
a problem with the Tire Pressure
Monitor System. The light flashes
for about a minute and stays on
steady for the remainder of the
ignition cycle. This sequence
repeats with every ignition cycle.
See Tire Pressure Monitor
Operation
on page 10‑53for
more information.

Engine Oil Pressure Light
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.

Notice: Lack of proper engine
oil maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.

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.

Lighting 6-9
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.
EPM works to prevent excessive
discharge of the battery. It does this
by balancing the generator's output
and the vehicle's electrical needs.
It can increase engine idle speed to
generate more power, whenever
needed. It can temporarily reduce
the power demands of some
accessories.Normally, these actions occur in
steps or levels, without being
noticeable. In rare cases at the
highest levels of corrective action,
this action may be noticeable to the
driver. If so, a Driver Information
Center (DIC) message might be
displayed, such as BATTERY
SAVER ACTIVE, BATTERY
VOLTAGE LOW, or LOW BATTERY.
If one of these messages displays,
it is recommended that the driver
reduce the electrical loads as much
as possible. See
Driver Information
Center (DIC) on page 5‑18.Battery Power Protection
The dome lamp is shut off if it is left
on for more than 20 minutes when
the ignition is in LOCK/OFF. This
helps to prevent the battery from
being drained.
