blown bulbs, a blown protection fuse or a break in the
electrical connection.
9. Door Ajar IndicatorThis indicator will illuminate when one or
more door(s) are not fully closed.
10. Glow Plug Light — If Equipped
This vehicle will inhibit engine cranking when the
transmission oil temperature is less than –22° F
(–30° C) and the oil temperature sensor reading indicates an
engine block heater has not been used. The Glow Plug light
will flash during in cold weather for up to 10 seconds. An
externally powered electric engine block heater is available
as optional equipment or from your authorized dealer.
Turning the ignition key to the ON/RUN position illu-
minates the Glow Plug Light, the light will turn off when glow plugs reach the established temperature. You can
start the engine immediately after the light turns off.
A blinking Glow Plug Light (together with a display
message) indicates a failure on glow plugs. Please see
your authorized dealer as soon as possible.

12. Oil Pressure Warning LightThis light indicates low engine oil pressure. The
light should turn on momentarily when the engine is
started. If the light turns on while driving, stop the
vehicle and shut off the engine as soon as possible. A
chime will sound when this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
13. Electronic Speed Control Set Indicator Light
This light will turn on when the electronic
speed control is set.
14. Charging System Light — If Equipped This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned to ON/RUN and remain on briefly as a bulb check. If the Charging System light
remains on, or comes on while driving, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See your au-
thorized dealer.
Refer to “Jump Starting Procedures” in “What To Do In
Emergencies” if jump starting is required.
15. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied or
that the brake fluid level is low.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction. In this case, the light will
remain on until the condition has been corrected. If the
20 UNDERSTANDING YOUR INSTRUMENT PANEL

problem is related to the brake booster, the ABS pump
will run when applying the brake and a brake pedal
pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed and the
brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the ABS are also equipped with
Electronic Brake Force Distribution (EBD). In the event of
an EBD failure, the Brake Warning Light will turn on
along with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately four seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.

The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
16. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part
of an Onboard Diagnostic (OBD) system which
monitors the emissions and engine control sys-
tem. If the bulb does not come on during
starting, have the condition investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
17. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
22 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealer for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
(Continued)
WARNING!(Continued)
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
18. Engine Temperature Warning Light
This light warns of an overheated engine condition. As
engine coolant temperatures rise and the gauge ap-
proaches H, this indicator will illuminate and a single
chime will sound after reaching a set threshold.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off. Also,
shift the transmission into NEUTRAL with the park
brake applied and idle the vehicle. If the temperature
reading does not return to normal, turn the engine off
immediately and call for service. Refer to “If Your Engine
Overheats” in “What To Do In Emergencies” for further
information.

19. Electronic Throttle Control (ETC) LightThis light informs you of a problem with
engine torque (or power) generation. If a prob-
lem is detected, the light will come on while the
engine is running. Cycle the ignition key when
the vehicle has completely stopped. The light should turn
off. If the light remains lit with the engine running, your
vehicle will usually be drivable (although performance
will be limited), see an authorized dealer for service as
soon as possible. If the light is flashing when the engine
is running, immediate service is required and you may
experience reduced performance, an elevated/rough idle
or engine stall and your vehicle may require towing. The
light will come on when the ignition is first turned to
ON/RUN and remain on briefly as a bulb check. If the
light does not come on during starting, have the system
checked by an authorized dealer. 20. TOW/HAUL — If Equipped
This light will illuminate when TOW HAUL
mode is selected.
21. Low Fuel Light
When the fuel level reaches approximately 3.0 gal (11.7
L), this light will turn on, and remain on until fuel is
added.
22. Fuel Gauge/Fuel Door Reminder When the ignition switch is in the ON/RUN
position, the pointer will show the level of fuel
remaining in the fuel tank. The fuel pump
symbol points to the side of the vehicle where
the fuel door is located.

23. Generic Warning LightThe Generic Warning Light will illuminate in
blinking mode if any of the following condi-
tions occur:
• Air Bag Warning Light Fault
• Engine Oil Pressure Sensor Failure
• Parking Sensor Failure
• Water In Fuel Presence
• Fuel Cutoff Intervention
• “Engine Minimum Oil Level”
• “Engine Min Oil Sensor Fail”
• Swivel Seat Malfunction
If the Generic Warning Light is blinking an air bag system
failure may be present, see an authorized dealer as soon
as possible. 24. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorized
dealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
25. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
4
UNDERSTANDING YOUR INSTRUMENT PANEL 25

vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.Your vehicle has also been equipped with a TPMS
malfunction strategy to indicate when the system is not
operating properly. When the system detects a malfunc-
tion, the low tire pressure telltale will flash for approxi-
mately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the low tire pressure telltale is illuminated, the system
may not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS telltale after replacing one or more tires or wheels
on your vehicle, to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to continue to
function properly.
26 UNDERSTANDING YOUR INSTRUMENT PANEL

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to an authorized dealership to have your
sensor function checked.NOTE:
The TPMS telltale is also accompanied by a “Low
Tire” message in the Electronic Vehicle Information Cen-
ter (EVIC). Refer to “Tire Pressure Monitoring System
(TPMS) in “Starting And Operating” for further informa-
tion.
26. Seat Belt Reminder Light
When the ignition switch is first turned to
ON/RUN, during the first six seconds from
key ON, if the driver ’s seat belt is unbuckled, a
continuous chime will sound and the light will
be ON. After the first six seconds or when driving, if the
driver ’s seat belt remains unbuckled, the seat belt re-
minder light will flash or remain on continuously. This
light also indicates if the front passengers are buckled or
not (when the vehicle is equipped with the seat belt alert
also for passenger/passengers).

27. Electronic Stability Control (ESC) OFF Indicator
LightThis light indicates the Electronic Stability Con-
trol (ESC) is off. Refer to “Electronic Stability
Control (ESC)” in “Starting And Operating” for
further information.
28. Electronic Stability Control (ESC) Activation/
Malfunction Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the
ON/RUN position. It should go out with the
engine running. If the “ESC Activation/Malfunction In-
dicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles (kilometers) at speeds greater than 30 mph (48 km/h), see
your authorized dealer as soon as possible to have the
problem diagnosed and corrected.
NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on
momentarily each time the ignition switch is turned
to ON/RUN.
• Each time the ignition is turned to ON/RUN, the
ESC system will be ON, even if it was manually
turned off previously.
• The ESC system will make buzzing or clicking
sounds and flash the ESC activation light when it is
active. This is normal; the sounds will stop when
ESC becomes inactive following the maneuver that
caused the ESC activation.
