2008 JEEP PATRIOT warning light

ESP/BAS Warning Light and ESP Indicator Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow “ESP/BAS Warning Light”
and the yellow “ESP Indicator Light” in the instrument
cluster both come on when the ignition switch is turned
to the ON position. They should both 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 BAS system, or
both. 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 “ESP Indicator Light” and the “ESP/BAS Warning
Light” come onmomentarilyeach time the ignition
switch is turned ON.
•Each time the ignition is turned ON, the ESP System
will be ON even if it was turned off previously.
•The ESP Control System will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESP becomes inactive following the
maneuver that caused the ESP activation.

10. Anti-Lock Brake Warning Light — If Equipped
This light monitors the Anti-Lock Brake System
(ABS) described elsewhere in this manual. This
light will come on when the ignition key is
turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on during 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 provided that 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 benefit of Anti-Lock
Brakes.The warning light should be checked frequently to assure
that it is operating properly. Turn the ignition key to the
ON position, but do not start the vehicle. The light
should come on. If the light does not come on, have the
system checked by an authorized dealer.

13. Engine Coolant Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the engine is critically hot, a warning chime
will sound 10 times. After the chime turns off, the
engine will still be critically hot until the light goes out.
14. Brake System Warning Light
This light monitors various brake functions, in-
cluding brake fluid level and parking brake appli-
cation. If the brake light turns on, it may indicate that the
parking brake is applied, there is a low brake fluid level
or there is a problem with the Anti-Lock Brake System
(ABS).
The dual-brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. Failure of 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 brake light on is danger-
ous. Part of the brake system may have failed. It will
take longer to stop the vehicle. You could have an
accident. Have the vehicle checked immediately.

will turn on along with the ABS Light. Immediate repair
to the ABS system is required.
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 approxi-
mately 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.
The light also will turn 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.15. Transmission Temperature Warning Light
During sustained high speed driving on hot
days, the automatic transaxle oil may become
too hot. If this happens, the transmission over-
heat indicator light will come on and the
vehicle will slow slightly until the automatic transaxle
cools down enough to allow a return to the requested
speed. If the high speed is maintained, the overheating
will reoccur as before in a cyclic fashion.
16. Security Alarm System Indicator Light — If
Equipped
This light will flash rapidly for several seconds when the
alarm system is arming. The light will begin to flash
slowly indicating that the system is armed.
