This warning light will illuminate when
the windshield washer fluid is low.
Refer to “Engine Compartment” in
“Servicing And Maintenance” for
further information.
Low Fuel Warning Light
When the fuel level reaches approxi -
mately 3.2 gal (12 L) this light will turn
on, and remain on until fuel is added.
A single warning chime will sound with
Low Fuel Warning.
Low Coolant Level Warning Light
This telltale will turn on to indicate the
vehicle coolant level is low.
Refer to “Fluids And Lubricants” in
“Technical Specifications” for further
information.
Loose Fuel Filler Cap Warning Light — If
Equipped
This warning light will illuminate when
the fuel filler cap is loose. Properly
close the filler cap to disengage the
light. If the light does not turn off,
please see an authorized dealer.
Trailer Merge Assist Indicator Light — If
Equipped
This indicator light will illuminate to
indicate when Trailer Merge Assist
has been activated.
Refer to “Blind Spot Monitoring (BSM)” in
“Safety” for further information.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that
the tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may
not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the indi -
cations corresponding to each tire. 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 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 pres
-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres -
sure. Driving on a significantly under-inflated
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair
kit and contact an authorized dealer as soon
as possible.

136GETTING TO KNOW YOUR INSTRUMENT PANEL
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 pres-
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi -
mately one minute and then remain continu -
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator 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 malfunction
telltale after replacing one or more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Anti-Lock Brake (ABS) Warning Light
This warning light monitors the
Anti-Lock Brake System (ABS). The
light will turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position
and may stay on for as long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is
required as soon as possible. However, the
conventional brake system will continue to
operate normally, assuming the Brake Warning
Light is not also on.
If the ABS light does not turn on when the igni
-
tion is placed in the ON/RUN or ACC/ON/RUN
position, have the brake system inspected by an
authorized dealer.
Rear Axle Locker Fault Indicator Light — If
Equipped
This warning light will illuminate to
indicate when a rear axle locker fault
has been detected.
Refer to “Axle Locker System — Power
Wagon Models Only (If Equipped)” in “Starting
And Operating” for further information.
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 operation or sensor
damage may result when using replacement
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 aftermarket tire
sealant it is recommended that you take your
vehicle to an authorized dealer to have your
sensor function checked.

SAFETY145
ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modifica -
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will
turn on when the ignition is placed in the ON/
RUN mode and may stay on for as long as four
seconds.
If the “Anti-Lock Brake Warning Light” remains
on or comes 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 “Anti-Lock
Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the
brake system should be serviced as soon as
possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning Light”
does not come on when the ignition is placed in
the ON/RUN mode, have the light repaired as
soon as possible.
Electronic Brake Control (EBC) System
Your vehicle is equipped with an advanced Elec -
tronic Brake Control (EBC) system . This system
includes Electronic Brake Force Distribution (EBD), Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Hill Start Assist (HSA),
Traction Control System (TCS), Electronic
Stability Control (ESC), and Electronic Roll Miti
-
gation (ERM). These systems work together to
enhance both vehicle stability and control in
various driving conditions.
Your vehicle may also be equipped with Trailer
Sway Control (TSC) and Hill Descent Control
(HDC).
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to
optimize the vehicle’s braking capability during
emergency braking maneuvers. The system
detects an emergency braking situation by
sensing the rate and amount of brake applica -
tion and then applies optimum pressure to the
brakes. This can help reduce braking distances.
The BAS complements the Anti-Lock Brake
System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive
the benefit of the system, you must apply
continuous braking pressure during the stop-
ping sequence, (do not “pump” the brakes). Do
not reduce brake pedal pressure unless braking
is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red “Brake System Warning Light” will turn
on when the ignition is placed in the ON/RUN
mode and may stay on for as long as four
seconds.
If the “Brake System Warning Light” remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the “Brake
System Warning Light” does not come on when
the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
WARNING!
The Brake Assist System (BAS) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. BAS cannot prevent collisions,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of
a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner,
which could jeopardize the user's safety or
the safety of others.
