GETTING TO KNOW YOUR INSTRUMENT PANEL133
Rear Axle Locker Fault Indicator Light —
If Equipped
This warning light will illuminate to
indicate when a rear axle locker fault has
been detected.
Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to
indicate a fault in the FCW System.
Contact an authorized dealer for service
Úpage 325.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning
properly and service is required. Contact
an authorized dealer for service.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal
a fault with the 4WD system. If the light
stays on or comes on during driving, it
means that the 4WD system is not
functioning properly and that service is required.
We recommend you drive to the nearest service
center and have the vehicle serviced immediately.
Cruise Control Fault Warning Light
This warning light will illuminate to
indicate the Cruise Control System is not
functioning properly and service is
required. Contact an authorized dealer.
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 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 pressure telltale
when one or more of your tires is significantly
underinflated. 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 pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation
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 underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
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.

134GETTING TO KNOW YOUR INSTRUMENT PANEL
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 approximately one minute
and then remain continuously 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.
YELLOW INDICATOR LIGHTS
Air Suspension Payload Protection
Indicator Light — If Equipped

setting Úpage 165.
Air Suspension Aerodynamic Height
Indicator Light— If Equipped
This light will illuminate when the air
suspension system is set to the
Aerodynamic setting.
Air Suspension Ride Height Raising
Indicator Light— If Equipped
This light will blink and alert the driver
that the vehicle is changing to a higher
ride height.
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.

162STARTING AND OPERATING
3. If the transfer case will not shift, a message
will appear on the cluster stating the 4WD shift
has canceled.
NOTE:
Before retrying a selection, make certain that all the
necessary requirements for selecting a new transfer
case position have been met. To retry the selection,
push the current position, wait five seconds, and
retry selection.

The SERV 4WD Warning Light monitors the
electronic shift four-wheel drive system. If this light
remains on after engine start-up or illuminates
during driving, it means that the four-wheel drive
system is not functioning properly and that service
is required.
NOTE:Do not attempt to make a shift while only the front
or rear wheels are spinning. This could cause
damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of the 2WD or 4WD HIGH positions at a given road
speed. Take care not to overspeed the engine and
do not exceed 25 mph (40 km/h).
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the drivetrain.
Because four-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
Shifting Procedure
If any of the requirements to select a new
transfer case position have not been met, then
the transfer case will not shift. The position indi -
cator light for the previous position will remain
on and the newly selected position indicator
light will continue to flash until all the require -
ments for the selected position have been met.
If all the requirements to select a new transfer
case position have been met, then the current
position indicator light will turn off and the
selected position indicator light will flash until
the transfer case completes the shift. When the
shift is complete, the position indicator light for
the selected position will stop flashing and
remain on.

164STARTING AND OPERATING
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD
HIGH, 4WD LOW, and 4WD AUTO) are located in
the instrument cluster and indicate the current
and desired transfer case selection. When you
select a different transfer case position, the
indicator lights will do the following:

1. The current position indicator light will turn off.

2. The selected position indicator light will flash until the transfer case completes the shift.
3. When the shift is complete, the indicator light for the selected position will stop flashing and
remain on.
If the transfer case does not shift into the desired
position, one or more of the following events may
occur:

1. The indicator light for the current position will remain on.

2. The newly selected position indicator light will continue to flash.
3. If the transfer case will not shift, there will be a
cluster message stating the 4WD shift has
canceled.
NOTE:Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met. To retry the
selection, push the current position, wait five
seconds, and retry selection.

AXLE LOCK SYSTEM — IF EQUIPPED
This vehicle is equipped with an electronically
locking rear differential. When engaged, this
differential locks the axle shafts forcing the wheels
to spin at an equal rate. The locking of the rear
differential should only be engaged during
low-speed, extreme off-road situations where one
wheel is likely to not be in contact with the ground.
It is not recommended to drive the vehicle with the
differentials locked on pavement due to the
reduced ability to turn and speed limitations.

AXLE LOCK Button
The locking rear axle is controlled by the AXLE
LOCK button.
Under normal driving conditions, the rear axle
should be unlocked.
During the command to lock the rear axle, the
indicator light will flash until the axle is locked.
After the lock command has been successfully
executed, the light will remain on solid.
Operating in 4WD LOW the locker can be engaged
up to 40 mph (64 km/h) and will remain engaged
throughout the 4WD LOW speed range.
CAUTION!
Do not lock the rear axle on hard surfaced
roads. The ability to steer the vehicle is
reduced and damage to the drivetrain may
occur when the axle is locked on hard
surfaced roads.
Do not try to lock the rear axle if the vehicle is
stuck and the tires are spinning. You can
damage drivetrain components. Lock the rear
axle before attempting situations or navi
-
gating terrain, which could possibly cause the
vehicle to become stuck.

3. Stop filling the DEF tank immediately when any of the following happen: DEF stops flowing
from the fill bottle into the DEF tank, DEF
splashes out the filler neck, or a DEF pump
nozzle automatically shuts off.
4. Reinstall cap onto DEF tank.
Filling The Def Tank In Cold Climates
Your vehicle is equipped with an automatic DEF
heating system. This allows the DEF injection
system to operate properly at temperatures below
12°F (-11°C). If your vehicle is not in operation for
an extended period of time with temperatures
below 12°F (-11°C), the DEF in the tank may
freeze. Do not overfill the DEF tank. If the tank is
overfilled and freezes, it could be damaged.
Extra care should be taken when filling with
portable containers to avoid overfilling. Keep an
eye on the DEF gauge in your instrument cluster.
You may safely add a maximum of 2 gallons
(7.6 Liters) when your DEF gauge is reading at
the half mark.
VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total permissible weight of your
vehicle including driver, passengers, vehicle,
options and cargo. The label also specifies
maximum capacities of front and rear Gross Axle
Weight Rating (GAWR). Total load must be limited
so GVWR and front and rear GAWR are not
exceeded.
PAYLOAD
The payload of a vehicle is defined as the allowable
load weight a truck can carry, including the weight
of the driver, all passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the
front and rear axles. The load must be distributed
in the cargo area so that the GAWR of each axle is
not exceeded.
Each axle GAWR is determined by the components
in the system with the lowest load carrying capacity
(axle, springs, tires or wheels). Heavier axles or
suspension components sometimes specified by
purchasers for increased durability does not
necessarily increase the vehicle's GVWR.
When DEF is spilled, clean the area immedi -
ately with water and use an absorbent mate -
rial to soak up the spills on the ground.
Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it
can result in severe damage to your engine,
including but not limited to failure of the fuel
pump and injectors.
Never add anything other than DEF to the tank
– especially any form of hydrocarbon such as
diesel fuel, fuel system additives, gasoline, or
any other petroleum-based product. Even a
very small amount of these, less than
100 parts per million or less than 1 oz. per
78 gallons (295 liters) will contaminate the
entire DEF system and will require replace -
ment. If owners use a container, funnel or
nozzle when refilling the tank, it should either
be new or one that has only been used for
adding DEF. Mopar® provides an attachable
nozzle with its DEF for this purpose.
CAUTION!
