Warning Lights And Messages; Red Warning Lights - Jeep WRANGLER 2023 Owner's Manual

WARNING LIGHTS AND MESSAGES

The warning/indicator lights will illuminate in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the
information contained in the Owner's Manual, which
you are advised to read carefully in all cases. Always
refer to the information in this chapter in the event of a
failure indication. All active telltales will display first if
applicable. The system check menu may appear differ-
ent based upon equipment options and current vehicle
status. Some telltales are optional and may not appear.

RED WARNING LIGHTS

Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for
four to eight seconds as a bulb check when
the ignition is placed in the ON/RUN or ACC/
ON/RUN position. This light will illuminate with a single
chime when a fault with the air bag has been detected,
it will stay on until the fault is cleared. If the light is not
on during startup, stays on, or turns on while driving,
have the system inspected at an authorized dealer as
soon as possible.
Brake Warning Light
This warning 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, that the brake fluid level is low, or that there is
a problem with the Anti-Lock Brake System reservoir.
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 or that a problem
with the Brake Booster has been detected by the Anti-
Lock Brake System (ABS) / Electronic Stability Control
(ESC) system. In this case, the light will remain on until
the condition has been corrected. If the 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
capacity 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 conditions. The
vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
WARNING!
Driving a vehicle with the red 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 a colli-
sion. Have the vehicle checked immediately.
GETTING TO KNOW YOUR INSTRUMENT PANEL
Vehicles equipped with the Anti-Lock Brake System
(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
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.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:
This light shows only that the parking brake is applied.
It does not show the degree of brake application.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Con-
tact an authorized dealer as soon as possible.
This indicates a possible problem with the electrical
system or a related component.
Door Open Warning Light
This indicator will illuminate when a door is
ajar/open and not fully closed.
