Warning LightWhat It Means What To Do
TPMS FAILURE
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 in sequence.
Note:
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sudden braking and steering. Repair
immediately using the dedicated tire repair kit and
contact your authorized dealer as soon as possible.
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 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

Warning LightWhat It Means What To Do
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 dealership to have
your sensor function checked.
Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Immediately
restore the correct inflation pressure using the Tire
Repair Kit (refer to “Tire Repair Kit” in “In Case Of
Emergency”) and contact an authorized dealer as soon
as possible.
Tire Pressure Low
The warning light switches on 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. In any situation in which the message on the display is
"See Manual", it is ESSENTIAL to refer to “Driving
Assistance Systems” in “Safety,” strictly complying with
the indications that you find there.

and environmental conditions are such
that they wouldn't cause the tires to
slip. When the road and environmental
conditions require better traction, the
vehicle automatically goes to AWD
mode.
The driving mode, RWD or AWD, is
shown on the instrument cluster
display.
Note:If the system failure symbol
switches on, after starting the engine or
while driving, it means that the AWD
system is not working properly. If the
warning message activates frequently, it
is recommended to carry out the
maintenance operations.
Electronic Stability
Control (ESC) System
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
The ESC system uses sensors installed
on the car to determine the path that
the driver intends to follow and
compares it with the car’s effective
path. When the real path deviates from
the desired path, the ESC system
intervenes to counter the vehicle’s
understeer or oversteer.
Oversteer occurs when the car is
turning more than it should according
to the angle of the steering wheel.
Understeer occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
System Intervention
The intervention of the system is
indicated by the flashing of the ESC
warning light on the instrument panel,
to inform the driver that the vehicle
stability and grip are critical.
Warning!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESC
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Vehicle modifications, or failure to
properly maintain your vehicle, may change
the handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the
steering system, suspension, braking
system, tire type and size or wheel size
may adversely affect ESC performance.
Improperly inflated and unevenly worn tires
may also degrade ESC performance. Any
vehicle modification or poor vehicle
maintenance that reduces the effectiveness
of the ESC system can increase the risk of
loss of vehicle control, vehicle rollover,
personal injury and death.
Traction Control System
(TCS)
The system automatically operates in
the event of slipping, loss of grip on wet
roads (hydroplaning), and acceleration
on one or both drive wheels on roads
that are slippery, snowy, icy, etc.
Depending on the slipping conditions,
two different control systems are
activated:
If the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine.
If the slipping only involves one of the
drive wheels, the Brake Limited
Differential (BLD) function is activated,
automatically braking the wheel which
is slipping (the behavior of a self-locking
differential is simulated). This will
increase the engine torque transferred
to the wheel which isn't slipping.

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 dealership to have your
sensor function checked.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which could
damage the TPMS sensor.
INSUFFICIENT TIRE PRESSURE
INDICATION
If an insufficient pressure value is
detected on one or more tires, the
warning light in the instrument
cluster will display alongside the
dedicated messages, the system will
highlight the tire or tires with insufficient
pressure graphically, and an acoustic
signal will be emitted. In this case, stop the car, check the
inflation pressure of each tire, and
inflate the necessary tire or tires to the
correct cold inflation pressure value,
shown on the display or in the
dedicated TPMS menu.
TPMS TEMPORARILY DISABLED
TPMS Check Message
When a system fault is detected, the
“Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds, and
then remain on solid. The system fault
will also sound a chime. If the ignition is
cycled, this sequence will repeat,
provided that the system fault still
exists. The “Tire Pressure Monitoring
Telltale Light” will turn off when the fault
condition no longer exists. A system
fault can occur due to any of the
following:
Jamming due to electronic devices
or driving next to facilities emitting the
same radio frequencies as the TPMS
sensors.
Installing some form of aftermarket
window tinting that affects radio wave
signals.
Lots of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors. After the punctured tire has been
repaired with the original tire sealant
contained in the TireKit, the previous
condition must be restored so that the
warning light is off during normal
driving.
TPMS Deactivation
The TPMS can be deactivated by
replacing all four wheel and tire
assemblies (road tires) with wheel and
tire assemblies that do not have TPMS
Sensors, such as when installing winter
wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first replace all
four wheel and tire assemblies (road
tires) with tires not equipped with Tire
Pressure Monitoring (TPM) Sensors.
Then, drive the vehicle for 10 minutes
above 15 mph (24 km/h). The TPMS
will chime, the "TPM Telltale Light" will
flash on and off for 75 seconds and
then remain on. The instrument cluster
will display the “SERVICE TPM
SYSTEM” message and then display
dashes (--) in place of the pressure
values.
Beginning with the next ignition switch
cycle, the TPMS will no longer chime or
display the “SERVICE TPM SYSTEM”
message in the instrument cluster.
Instead, dashes (--) will remain in place
of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires)
with tires equipped with TPM sensors.

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.
Tire Size
The tire size on the Vehicle Certification
Label represents the actual tire size on
your vehicle. Replacement tires must be
equal to the load capacity of this tire
size.
Rim Size
This is the rim size that is appropriate
for the tire size listed.
Inflation Pressure
This is the cold tire inflation pressure for
your vehicle for all loading conditions up
to full GAWR.
Curb Weight
The curb weight of a vehicle is defined
as the total weight of the vehicle with all
fluids, including vehicle fuel, at full
capacity conditions, and with no
occupants or cargo loaded into the
vehicle. The front and rear curb weight
values are determined by weighing your
vehicle on a commercial scale before
any occupants or cargo are added.
Loading
The actual total weight and the weight
of the front and rear of your vehicle at
the ground can best be determined by
weighing it when it is loaded and ready
for operation.The entire vehicle should first be
weighed on a commercial scale to
insure that the GVWR has not been
exceeded. The weight on the front and
rear of the vehicle should then be
determined separately to be sure that
the load is properly distributed over the
front and rear axle. Weighing the vehicle
may show that the GAWR of either the
front or rear axles has been exceeded
but the total load is within the specified
GVWR. If so, weight must be shifted
from front to rear or rear to front as
appropriate until the specified weight
limitations are met. Store the heavier
items down low and be sure that the
weight is distributed equally. Stow all
loose items securely before driving.
Improper weight distributions can have
an adverse effect on the way your
vehicle steers and handles and the way
the brakes operate.
Caution!
Do not load your vehicle any heavier than
the GVWR or the maximum front and rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your
vehicle handles. This could cause you to
lose control. Also overloading can shorten
the life of your vehicle.

Spare Tires — If
Equipped
Note:
For vehicles equipped with Tire Repair
Kit instead of a spare tire, please refer
to “Tire Repair Kit” in “In Case Of
Emergency” for further information.
Caution!
Because of the reduced ground clearance,
do not take your vehicle through an
automatic car wash with a compact or
limited use temporary spare installed.
Damage to the vehicle may result.
Spare Tire Matching Original
Equipped Tire And Wheel — If
Equipped
Your vehicle may be equipped with a
spare tire and wheel equivalent in look
and function to the original equipment
tire and wheel found on the front or rear
axle of your vehicle. This spare tire may
be used in the tire rotation for your
vehicle. If your vehicle has this option,
refer to an authorized tire dealer for the
recommended tire rotation pattern.
Compact Spare Tire — If
Equipped
The compact spare is for temporary
emergency use only. You can identify if
your vehicle is equipped with a
compact spare by looking at the spare
tire description on the Tire and Loading
Information Placard located on the
driver’s side door opening or on the
sidewall of the tire. Compact spare tire
descriptions begin with the letter “T” or
“S” preceding the size designation.
Example: T145/80D18 103M.
T,S=Temporary Spare Tire
Since this tire has limited tread life, the
original equipment tire should be
repaired (or replaced) and reinstalled on
your vehicle at the first opportunity.
Do not install a wheel cover or attempt
to mount a conventional tire on the
compact spare wheel, since the wheel
is designed specifically for the compact
spare tire. Do not install more than one
compact spare tire and wheel on the
vehicle at any given time.
Warning!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have
limited tread life. When the tread is worn to
the tread wear indicators, the temporary
use spare tire needs to be replaced. Be
sure to follow the warnings, which apply to
your spare. Failure to do so could result in
spare tire failure and loss of vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary
emergency use only. This tire may look
like the originally equipped tire on the
front or rear axle of your vehicle, but it is
not. This spare tire may have limited
tread life. When the tread is worn to the
tread wear indicators, the temporary
use full size spare tire needs to be
replaced. Since it is not the same as
your original equipment tire, replace (or
repair) the original equipment tire and
reinstall on the vehicle at the first
opportunity.

SERVICING AND MAINTENANCE

Caution!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven cleaner.
These products may damage the wheel's
protective finish. Such damage is not covered
by the New Vehicle Limited Warranty. Only
car wash soap, MOPAR Wheel Cleaner or
equivalent is recommended.
Note:
If you intend parking or storing your
vehicle for an extended period after
cleaning the wheels with wheel cleaner,
drive your vehicle for a few minutes
before doing so. Driving the vehicle and
applying the brakes when stopping will
reduce the risk of brake rotor corrosion.
Dark Vapor Or Black Satin Chrome
Wheels
Caution!
If your vehicle is equipped with Dark Vapor
or Black Satin Chrome wheels DO NOT USE
wheel cleaners, abrasives or polishing
compounds. They will permanently damage
this finish and such damage is not covered
by the New Vehicle Limited Warranty. USE
ONLY MILD SOAP AND WATER WITH A
SOFT CLOTH. Used on a regular basis; this
is all that is required to maintain this finish.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, and
Winter). Traction levels may vary
between different all season tires. All
season tires can be identified by the
M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires
only in sets of four; failure to do so may
adversely affect the safety and handling
of your vehicle.
Summer Or Three Season Tires
— If Equipped
Summer tires provide traction in both
wet and dry conditions, and are not
intended to be driven in snow or on ice.
If your vehicle is equipped with Summer
tires, be aware these tires are not
designed for Winter or cold driving
conditions. Install Winter tires on your
vehicle when ambient temperatures are
less than 40°F (5°C) or if roads are
covered with ice or snow. For more
information, contact an authorized
dealer.
Summer tires do not contain the all
season designation or mountain/
snowflake symbol on the tire sidewall.
Use Summer tires only in sets of four;
failure to do so may adversely affect the
safety and handling of your vehicle.
Warning!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the
use of snow tires during the Winter.
Snow tires can be identified by a
“mountain/snowflake” symbol on the
tire sidewall.If you need snow tires,
select tires equivalent
in size and type to the
original equipment
tires. Use snow tires
only in sets of four;
failure to do so may
adversely affect the safety and handling
of your vehicle.
Snow tires generally have lower speed
ratings than what was originally
equipped with your vehicle and should
not be operated at sustained speeds
over 75 mph (120 km/h). For speeds
above 75 mph (120 km/h) refer to
original equipment or an authorized tire
dealer for recommended safe operating
speeds, loading and cold tire inflation
pressures.
