If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefit of Anti-Lock
Brakes.
The operation of the ABS light can be checked by turning
the ignition switch from the OFF position to the ON
position. The light should illuminate for approximately
four seconds. The light should then turn off unless a
brake fault is detected. If the light does not illuminate,
have the light inspected by an authorized dealer.
10. Charging System Warning Light
This light shows the status of the electrical charg-
ing system. The light should come on for three
seconds when the ignition is first turned ON. If the light
comes back on immediately or comes on while driving, it
means that there is a problem with the charging system
or the battery is low. Also, a chime will sound if the light
comes back on. See your authorized dealer immediately.11. Temperature Gage
Indicates engine coolant temperature. Any read-
ing within the normal range indicates that the
cooling system is operating satisfactorily.
The gage pointer will likely indicate a higher temperature
(above center scale) when driving in hot weather, up
mountain grades, in heavy stop and go traffic, or when
towing a trailer. It should not be allowed to exceed the
upper limits of the normal operating range.
If the pointer rises to the red zone (five chimes will
occur), pull over and stop the vehicle. Do not turn the
engine off. Idle the vehicle with the air conditioning
turned off, until the pointer drops back into the normal
range. If the engine remains in the high range, turn the
engine off and call for service.

If the warning light comes on and remains on while
driving, stop the vehicle and shut off the engine. DO
NOT OPERATE THE VEHICLE UNTIL THE CAUSE IS
CORRECTED. Also, a single chime will sound.
16. Transmission Temperature Warning Light
This light indicates that there is excessive trans-
mission fluid temperature that might occur with
severe usage such as trailer towing or snow plowing. If
this light comes on, stop the vehicle and run the engine at
idle or faster, with the transmission in N (Neutral) until
the light goes off.
17. Part Time Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the PART TIME four–wheel drive high range
mode, and the front and rear driveshafts are
mechanically locked together forcing the front and rear
wheels to rotate at the same speed.18. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the light comes on, it may indi-
cate that the parking brake is applied, or there
is a low brake fluid level. On vehicles equipped with
Anti-Lock brakes (ABS), it may also indicate an ABS
malfunction that could lead to reduced braking perfor-
mance.

WARNING!
Driving a vehicle with the BRAKE warning light on
is dangerous. A significant decrease in braking per-
formance or vehicle stability during braking may
occur. It will take you longer to stop the vehicle or
will make your vehicle harder to control. You could
have an accident. Have the vehicle checked immedi-
ately.
The operation of the BRAKE warning light can be
checked by turning the ignition switch from the OFF
position to the ON position. The light should illuminate
for approximately two 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.Also, the light will come on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
If the parking brake is off and the light remains on, have
the brake system inspected as soon as possible.
19. Full Time Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the FULL TIME four–wheel drive mode, and
employs the inter-axle differential which al-
lows the front and rear wheels to rotate at
different speeds.
20. Sentry Key/Security Alarm Indicator Light — If
Equipped
Refer to “Sentry Key Immobilizer System” or “Vehicle
Security Alarm” in Section 2 of this manual for more
information.

26. Electronic Throttle Control (ETC) Warning Light —
If Equipped
This light informs you of a problem with the
Electronic Throttle Control System. If a prob-
lem is detected while the engine is running, the
light will either stay on or flash depending on
the nature of the problem. Cycle the ignition key when
the vehicle is safely and completely stopped and the gear
selector is placed in the P (Park) position. The light
should turn off. If the light remains on with the engine
running, your vehicle will usually be drivable, however,
see your dealer for service as soon as possible.
If the light continues to flash 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 on and remainon briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
NOTE:“Two-footed” driving is not recommended. In-
advertently driving with the brake pedal depressed for
more than a few seconds when the accelerator pedal is
held in place can cause the ETC system to assume that a
stuck accelerator pedal has occurred. This will result in a
loss of power. Returning the brake pedal to its normal
position or moving the accelerator pedal will cancel this
condition. If the depressed brake pedal and the constant
accelerator pedal position are maintained for an extended
period of time, the ETC warning light will begin to flash
and continue until the ignition switch is cycled in the
same manner as above.

27. Electronic Stability Program (ESP) Warning
Light/Brake Assist System (BAS) Warning Light — If
Equipped
The ESP/BAS warning light in the instrument
cluster comes on when the ignition switch is
turned to the “ON” position. The light should
go out with the engine running. If the ESP/
BAS warning light comes on continuously with the
engine running, a malfunction has been detected in either
the ESP or the BAS system. If this light stays illuminated,
have the ESP and BAS checked at your authorized dealer
as soon as possible. Refer to “Electronic Brake Control
System” in Section 5 for more information.28. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light —
If Equipped
If this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the ESP, or TCS — if
equipped. The indicator light will flash when the ESP or
TCS System is active and helping to improve vehicle
stability. If the indicator light is on solid, ESP or TCS may
not be able to function normally. Refer to “Electronic
Brake Control System” in Section 5 for more information.
