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.
ESC Operating Modes
NOTE:Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs. Partial Off
The “Partial Off” mode is intended for times when a more
spirited driving experience is desired. This mode may
modify TCS and ESC thresholds for activation, which
allows for more wheel spin than normally allowed. This
mode may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily push the
“ESC Off” button and the “ESC Off Indicator Light” will
illuminate. To turn the ESC on again, momentarily push
the “ESC Off” button and the “ESC Off Indicator Light”
will turn off.
NOTE:
When driving with snow chains, or when starting
off in deep snow, sand, or gravel, it may be desirable to
allow more wheel spin. This can be accomplished by
momentarily pushing the “ESC Off” button to enter partial
mode “Partial Off” mode. Once the situation requiring
“Partial Off” mode is overcome, turn ESC back on by
momentarily pushing the “ESC Off” button. This may be
done while the vehicle is in motion.

VEHICLE LOADING
Certification Label
As required by National Highway Traffic Safety Adminis-
tration regulations, your vehicle has a certification label
affixed to the driver’s side door or pillar.
This label contains the month and year of manufacture,
Gross Vehicle Weight Rating (GVWR), Gross Axle Weight
Rating (GAWR) front and rear, and Vehicle Identification
Number (VIN). A Month-Day-Hour (MDH) number is
included on this label and indicates the Month, Day and
Hour of manufacture. The bar code that appears on the
bottom of the label is your VIN.
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 axle systems (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 in-
creased durability does not necessarily increase the vehi-
cle’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.

CAUTION!
Recovery feature:
•Is to be used by a professional ONLY.
• Is used only to provide recovery of the vehicle.
• Is NOT to be used to recover secondary vehicle.
• Is NOT to be used for transporting the vehicle over
the road, i.e. “Flat Towing”.
Recovery load should:
• Be applied at constant speed.
• Be applied parallel to the center line of the length of
the vehicle.
• Not be an abrupt acceleration.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode, not the ACC mode.
NOTE: The Safehold feature will engage the Electric Park
Brake whenever the driver’s door is opened (if the ignition
is ON, transmission is not in PARK, and brake pedal is
released). If you are towing this vehicle with the ignition in
the ON/RUN mode, you must manually disable the Elec-
tric Park Brake each time the driver’s door is opened, by
pressing the brake pedal and then releasing the EPB. If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK in
order to move the vehicle.
CAUTION!
•
Do not use sling-type equipment when towing.
Vehicle damage may occur.
• When securing the vehicle to a flatbed truck, do not
attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.
• Ensure that the Electric Park Brake is released, and
remains released, while being towed.

WARNING!(Continued)
may change suspension dimensions and perfor-
mance characteristics, resulting in changes to steer-
ing, handling, and braking of your vehicle. This can
cause unpredictable handling and stress to steering
and suspension components. You could lose control
and have a collision resulting in serious injury or
death. Use only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have a collision.
• Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (Spring,
Summer, Fall, and Winter). Traction levels may vary be-
tween 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 condi-
tions, 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 am-
bient 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.
554 SERVICING AND MAINTENANCE

CAUTION!(Continued)
Only car wash soap, Mopar Wheel Cleaner or equiva-
lent 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 and apply the brakes to remove
the water droplets from the brake components. This activ-
ity will remove the red rust on the brake rotors and prevent
vehicle vibration when braking.
Dark Vapor Chrome, Black Satin Chrome, or Low Gloss
Clear Coat Wheels
CAUTION!
If your vehicle is equipped with these specialty
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. HAND WASH ONLY US-
ING MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis; this is all that is
required to maintain this finish.
Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body clear-
ance. Follow these recommendations to guard against
damage:
• Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer.
• Install on front tires only.
• For a 235/65R17 or 235/60R18 tire, use of a snow
traction device with a maximum projection of 9 mm
beyond the tire profile is recommended.
WARNING!
Using tires of different size and type (M+S, Snow)
between front and rear axles can cause unpredictable
handling. You could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
• Because of restricted traction device clearance be-
tween tires and other suspension components, it is
