Fuel System Messages
The following chart contains a list of different messages that may appear in the instrument cluster, depending on different system or fuel
conditions. Use the descriptions to interpret what the message means and determine the best action to take.
MESSAGEDESCRIPTION
Diesel Emissions Additive AdBlue® Warning Messages:
Low Diesel Emissions Additive
AdBlue® Level Warning The first low level warning will be given at around a 1,490 miles (2,400 km) range, and is determined
according to the current consumption rate. The “AdBlue® Low Level” warning light and message will
display on the instrument panel. The AdBlue® low level warning light will remains lit until the AdBlue®
tank is topped up with at least 1.32 gallons (5 Liters) of AdBlue®.
If the level is not resolved, an additional warning appear whenever a certain threshold is reached until it
will no longer be possible to start the engine.
When 125 miles (200 km) are remaining before the AdBlue® tank is empty, a message will appear on
the instrument panel, accompanied by a buzzer sound. When the range is at 0, the display will show a
dedicated message (if equipped). In this case, the engine will not restart.
It will be possible to restart the engine again as soon as AdBlue® is added; the minimum amount
required is 1.32 gallons (5 Liters). Fill the AdBlue® tank as soon as possible with at least 1.32 gallons
(5 Liters) of AdBlue®. If filling is completed with autonomy tank AdBlue® to zero, it could be possible
to wait 2 minutes before starting the vehicle.
NOTE:
When the AdBlue® tank is empty, and the vehicle is stopped, it is no longer possible to restart the vehicle
until a minimum of 1.32 gallons (5 Liters) of AdBlue® is added to the AdBlue® tank.

WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate
in the instrument panel together with a dedi-
cated message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive. 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 different based upon
equipment options and current vehicle
status. Some telltales are optional and may
not appear.
Red Warning Lights
— Seat Belt Reminder Warning Light
This warning light indicates when the driver
or passenger seat belt is unbuckled. When
the ignition is first placed in the ON/RUN or
ACC/ON/RUN position and if the driver’s seat
belt is unbuckled, a chime will sound and
the light will turn on. When driving, if the
driver or front passenger seat belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime
will sound.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
— 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 either 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.
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.

— 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
indications corresponding to each tire. Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom
-
mended 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 Moni -
toring System (TPMS) that illuminates a low
tire pressure warning light when one or more
of your tires is significantly under-inflated.
Accordingly, when the low tire pressure
warning light illuminates, you should stop
and check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated 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 pressure 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 approx
-
imately 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.

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.

will be on solid when HDC is armed. HDC can
only be armed when the transfer case is in
the 4WD LOW position and the vehicle speed
is less then 30 mph (48 km/h). If these
conditions are not met while attempting to
use the HDC feature, the HDC indicator light
will flash on/off.
— LaneSense Indicator Light — If
Equipped
When the LaneSense system is ON, but not
armed, the LaneSense indicator light illumi -
nates solid white. This occurs when only left,
right, or neither lane line has been detected.

SAFETY
SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock,
and enhances vehicle control during braking.
The ABS performs a self-check cycle to
ensure that the ABS is working properly each
time the vehicle is started and driven. During
this self-check, you may hear a slight
clicking sound as well as some related motor
noises.
ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow,
gravel, bumps, railroad tracks, loose debris,
or panic stops may increase the likelihood of
ABS activation(s). You also may experience the following when
ABS activates:
The ABS motor noise (it may continue to
run for a short time after the stop).
The clicking sound of solenoid valves
Brake pedal pulsations
A slight drop of the brake pedal at the end
of the stop
NOTE:
These are all normal characteristics of ABS.
ABS is designed to function with the Original
Equipment Manufacturing (OEM) tires.
Modification may result in degraded ABS
performance.
WARNING!
The ABS contains sophisticated elec-
tronic equipment that may be suscep-
tible to interference caused by
improperly installed or high output radio
transmitting equipment. This interfer -
ence can cause possible loss of anti-lock
braking capability. Installation of such
equipment should be performed by qual -
ified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may
lead to a collision. Pumping makes the
stopping distance longer. Just press
firmly on your brake pedal when you
need to slow down or stop.
The ABS cannot prevent the natural laws
of physics from acting on the vehicle, nor
can it increase braking or steering effi -
ciency beyond that afforded by the
condition of the vehicle brakes and tires
or the traction afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The capabilities of an ABS equipped
vehicle must never be exploited in a
reckless or dangerous manner that could
jeopardize the user’s safety or the safety
of others.
