WARNING LIGHTS AND CHIMES
Warning lights and gauges can alert you to a vehicle condition that may
become serious enough to cause expensive 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
bulb works. If any light remains on after starting the vehicle, refer to the
respective system warning light for additional information.
Note:Some Warning Lights are reconfigurable telltale (RTT) indicator
lights and will illuminate in the Message Center Display and function the
same as the warning light.
Service engine soon:TheService
engine soonindicator light
illuminates when the ignition is first
turned to the ON position to check
the bulb and to indicate whether the vehicle is ready for
Inspection/Maintenance (I/M) testing. Normally, theService engine soon
light will stay on until the engine is cranked, then turn itself off if no
malfunctions are present. However, if after 15 seconds theService
engine soonlight blinks eight times, it means that the vehicle is not
ready for I/M testing. See theReadiness for Inspection/Maintenance
(I/M) testingin theMaintenance and Specificationschapter.
Solid illumination after the engine is started indicates the On Board
Diagnostics System (OBD-II) has detected a malfunction. Refer toOn
board diagnostics (OBD-II)in theMaintenance and Specifications
chapter. If 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 have your vehicle serviced
immediately by your authorized dealer.

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.
Powertrain malfunction/reduced
power (RTT) (if equipped):
Displays when the engine has
defaulted to a ’limp-home’ operation.
Report the fault to a dealer at the
earliest opportunity.
Brake system warning light: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, seek service immediately from your authorized dealer. Illumination
after releasing the parking brake indicates low brake fluid level and the
brake system should be inspected immediately by your authorized dealer.
Driving a vehicle with the brake system warning light on is
dangerous. A significant decrease in braking performance may
occur. It will take you longer to stop the vehicle. Have the vehicle
checked by your authorized dealer. Driving extended distances with
the parking brake engaged can cause brake failure and the risk of
personal injury.
Anti-lock brake system:If the
ABS light stays illuminated or
continues to flash, a malfunction has
been detected, have the system
serviced immediately by your
authorized dealer. Normal braking is still functional unless the brake
warning light also is illuminated.

Low tire pressure warning (if
equipped):Illuminates when your
tire pressure is low. If the light
remains ON at start up or while
driving, the tire pressure should be
checked. Refer toInflating Your Tiresin theTires, Wheels and
Loadingchapter. When the ignition is first turned to ON, the light will
illuminate for 3 seconds to ensure the bulb is working. If the light does
not turn ON or begins to flash, have the system inspected by your
authorized dealer. For more information on this system, refer to
Understanding Your Tire Pressure Monitoring Systemin theTires,
Wheels and Loadingchapter.
Low fuel (RTT) (if equipped):
Displays when the fuel level in the
fuel tank is at or near empty (refer
toFuel gaugein this chapter).
Check fuel cap (RTT) (if
equipped):Displays when the fuel
cap may not be properly installed.
Continued driving with this light on
may cause the Service engine soon
warning light to come on. Refer to
Fuel filler capin theMaintenance and Specificationschapter.
Low washer fluid (RTT) (if
equipped):Displays when the
windshield washer fluid is low.
O/D off:Illuminates when the
overdrive function of the
transmission has been turned off,
refer to theDrivingchapter. If the
light does not illuminate, have the transmission serviced soon, or damage
may occur.
AdvanceTrac
(RTT) (if
equipped):Displays when the
AdvanceTrac
with RSC system is
active. If the light remains on, have
the system serviced immediately,
refer to theDrivingchapter for more information.

Tachometer:Indicates the engine
speed in revolutions per minute.
Driving with your tachometer
pointer continuously at the top of
the scale may damage the engine.
Battery voltage gauge:Indicates
the battery voltage when the
ignition is in the ON position. If the
pointer moves and stays outside the
normal operating range, have the
vehicle’s electrical system checked
by your authorized dealer as soon as
possible.
Engine oil pressure gauge:
Indicates engine oil pressure. The
needle should stay in the normal
operating range (between “L” and
“H”). If the needle falls below the
normal range, stop the vehicle, turn
off the engine and check the engine
oil level. Add oil if needed. If the oil level is correct, have your vehicle
checked by your authorized dealer.
Fuel gauge:Indicates
approximately how much fuel is left
in the fuel tank (when the ignition
is in the ON position). The fuel
gauge may vary slightly when the
vehicle is in motion or on a grade.
Refer toFilling the tankin the
Maintenance and Specifications
chapter for more information.
The FUEL icon and arrow indicates which side of the vehicle the fuel
door is located.

AUXILIARY POWER POINT (12VDC)
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
on the instrument panel.
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
12 VDC/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 prevent the battery from being discharged, do not use the power
point longer than necessary when the engine is not running.
Always keep the power point caps closed when not being used.
A second auxiliary power point is
located on the rear side of the
center console. The power point is
accessible from the rear seats.

System check
Selecting this function from the SETUP MENU causes the message
center to cycle through each of the systems being monitored. For each
of the monitored systems, the message center will indicate either an OK
message or a warning message for 2 seconds.
Pressing the RESET stem cycles the message center through each of the
systems being monitored. If the RESET stem is not pressed, the display
will automatically scroll through each of the systems being monitored:
1. OIL LIFE
2. CHARGING SYSTEM
3. WASHER FLUID LEVEL
4. DOOR/LIFTGATE/GLASS AJAR
5. BRAKE SYSTEM
6. FUEL LEVEL (will only display if 50 miles or less to empty)
Oil life
An oil change is required whenever indicated by the message center and
according to the recommended maintenance schedule. USE ONLY
RECOMMENDED ENGINE OILS.
To reset the oil monitoring system to 100% after each oil change
[approximately 7,500 miles (12,070 km) or 6 months] perform the
following:
1. Press and release the RESET
stem to display “OIL LIFE = XXX%
HOLD RESET = NEW”.
2. Press and hold the RESET stem
for 2 seconds and release. Oil life is
set to XX% and “OIL LIFE SET TO
XX%” is displayed.
Note:Oil Life Start Value of 100% equals 7,500 miles (12,070 km) or 6
months. For example, setting Oil Life Start Value to 60% sets the Oil Life
Start Value to 3,000 miles (4,828 km) and 120 days.

RESET stem and clearing the warning message.
Warning messages are divided into four categories:
•They cannot be cleared until the condition is corrected.
•They will reappear on the display ten minutes from the reset if the
condition has not been corrected.
•They will not reappear until an ignition OFF-ON cycle has been
completed.
•They reappear if the condition clears then reoccurs within the same
ignition ON-OFF cycle.
This acts as a reminder that these warning conditions still exist within
the vehicle.
