WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause extensive repairs. A warning light may
illuminate when a problem exists with one of your vehicle’s functions.
Many lights will illuminate when you start your vehicle to make sure the
bulbs work. If any light remains on after starting the vehicle, refer to the
respective system light explanation later in this section for additional
information.
Note:Some warning lights are reconfigurable telltale (RTT) indicators;
they will display in the message center and function the same as the
warning light, but they will not display on startup as regular warning
lights do.
Service engine soon:The service
engine soon light illuminates when
the ignition is turned to the on
position to check the bulb.
•Illuminates with key on, vehicle off:If the light illuminates, the
service engine soon light is working properly.
•Illuminates with key on, vehicle off, then starts to blink:The
light illuminates when the ignition is turned to the on position to
check the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. If after 15 seconds the service
engine soon light blinks eight times, it means that the vehicle is not
ready for Inspection/Maintenance (I/M) testing. This can occur if the
vehicle’s engine or transmission has just been serviced, or the battery

need I/M testing, do nothing. The vehicle is designed to check the
emission control system during normal driving. If the vehicle needs
I/M testing, refer to theReadiness for Inspection/Maintenance (I/M)
testingsection in theMaintenance and Specificationschapter.
•Illuminates with engine running:The light stays on after the
engine is started. It indicates that the on board diagnostics system has
detected a problem with the engine, transmission or an
emission-related component or system. Contact your authorized dealer
as soon as possible. The vehicle will usually be drivable and will not
require towing. Refer toOn-board diagnostics (OBD-II)section in
theMaintenance and Specificationschapter for information on
temporary malfunctions that may not require vehicle service.
•Blinks with engine running:The light stays on after the engine is
started and sometimes blinks. It indicates that the On Board
Diagnostics System has detected an engine misfire problem with the
engine. While the light is blinking, engine misfire is occurring which
could damage your catalytic converter. Drive in a moderate fashion
(avoid heavy acceleration and deceleration) and contact your
authorized dealer as soon as possible.
WARNING:Under engine misfire conditions, excessive exhaust
temperatures could damage the catalytic converter, the fuel
system, interior floor coverings or other vehicle components, possibly
causing a fire.
Brake system warning:To confirm
the brake system warning light is
functional, it will momentarily
illuminate when the ignition is
turned to the on position (when the
engine is not running), or in a position between on and start, or by
applying the parking brake when the ignition is turned to the on
position. If the brake system warning light does not illuminate at this
time, contact your authorized dealer as soon as possible. Illumination
after releasing the parking brake indicates low brake fluid level or brake
system malfunction. Contact your authorized dealer as soon as possible.

compartment
3. Sliding arm rest.
WARNING:Use only soft cups in the cupholder. Hard objects
can injure you in a collision.
AUXILIARY POWER POINT (12V DC)
Power outlets are designed for accessory plugs only. Do not insert
any other object in the power outlet as this will damage the
outlet and blow the fuse. Do not hang any type of accessory or
accessory bracket from the plug. Improper use of the power
outlet can cause damage not covered by your warranty.
The auxiliary power point is located in the center console utility
compartment.
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12V DC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer toFuses and
relaysin theRoadside Emergencieschapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
•do not use the power point longer than necessary when the engine is
not running,

and should be inspected by an authorized dealer. If the vehicle has
continuous vibration or shudder in the steering wheel while braking, the
vehicle should be inspected by an authorized dealer.
Refer toWarning lights and
chimesin theInstrument Cluster
chapter for information on the brake
system warning light.
Four-wheel anti-lock brake system (ABS)
Your vehicle is equipped with an anti-lock braking system (ABS). This
system helps you maintain steering control during emergency stops by
keeping the brakes from locking. The ABS operates by detecting the
onset of wheel lockup during brake application and compensates for this
tendency. Noise from the ABS pump motor and brake pedal pulsation
may be observed during ABS braking; any pulsation or mechanical noise
you may feel or hear is normal. In addition, the ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal.
ABS warning lamp
The ABS lamp in the instrument
cluster momentarily illuminates
when the ignition is turned on. If
the light does not illuminate during
start up, remains on or flashes, the
ABS may be disabled and may need to be serviced.
Even when the ABS is disabled and
the ABS light is on, normal braking
is still effective. If your BRAKE
warning lamp illuminates with the
parking brake released, have your
brake system serviced immediately.
Using ABS
When hard braking is required, apply continuous force on the brake
pedal; do not pump the brake pedal since this will reduce the
effectiveness of the ABS and will increase your vehicle’s stopping
distance. The ABS will be activated immediately, allowing you to retain
full steering control during hard braking and on slippery surfaces.
However, the ABS does not decrease stopping distance and does not
decrease the time necessary to apply the brakes.

WARNING:If a failure has been detected within the
AdvanceTracsystem, the stability control light will illuminate
steadily, and you may hear a chime. If equipped with a message center,
the vehicle will also indicate a failure with the brake system. Have the
system serviced by an authorized dealer immediately.
The AdvanceTracsystem automatically enables each time the engine is
started. All features of the AdvanceTracsystem (TCS and ESC) are
active and monitor the vehicle from start-up. However, the system will
only intervene if the driving situation requires it.
The AdvanceTracsystem includes
one of these stability control
switches located on the instrument
panel.
The stability control light and the
stability control off light located in
the instrument cluster will
illuminate temporarily during
start-up as part of a normal system self-check. The stability control light
may illuminate (flash) during certain driving situations which cause the
AdvanceTracsystem to operate. If the stability control light illuminates
steadily, have the system serviced by an authorized dealer immediately. If
equipped with a message center, the vehicle will also indicate a failure
with the AdvanceTracsystem.
When AdvanceTracperforms a normal system self-check, some drivers
may notice a slight movement of the brake, and/or a rumble, grunting, or
grinding noise after startup and when driving off.
When an event occurs that activates AdvanceTracyou may experience
the following:
•A slight deceleration of the vehicle
•The stability control light will flash.
•If your foot is on the brake pedal, a vibration in the pedal
•If the driving condition is severe and your foot is not on the brake, the
brake pedal may move as the systems applies higher brake forces. You
may also hear a whoosh of air from under the instrument panel during
this severe condition.
•The brake pedal may feel stiffer than usual.
