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.

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

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).

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.

29. Anti-Lock Brake (ABS) LightThis light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, it
indicates that the anti-lock portion of the brake system is
not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of anti-lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer. 30. Vehicle Security Light
If during starting, the key code is not correctly
recognized, the Vehicle Security Light comes
on in the instrument panel. In this case, turn
the key to OFF and then to ON/RUN; if it is
still locked, try again with the other keys that come with
the vehicle. Contact an authorized dealer if you still
cannot start the engine.
If with the engine running the warning light flashes, this
means that the car is not protected by the engine inhibitor
device. Contact an authorized dealer to have all the keys
programmed.
31. Diesel Particulate Filter (DPF)
When the light illuminates solid in the EVIC,
the filter loading is above the specified range.
