(Continued)
TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight
stamped on your fascia/bumper or trailer hitch.
Weight Distribution
Consider the following items when computing the
weight on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or equip -
ment put in or on your vehicle.
The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the trailer
adds to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options
must be considered as part of the total load on
your vehicle
Úpage 306.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended. Perform the maintenance listed in the “Scheduled
Servicing”
Úpage 271 When towing a trailer,
never exceed the GAWR or GCWR ratings.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.
When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.
Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the hook retainers of the vehicle
hitch. Cross the chains under the trailer
tongue and allow enough slack for turning
corners.

STARTING AND OPERATING135
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when
towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Úpage 309.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK. For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL. Always, block or "chock" the trailer
wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch
utilized.

Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
Úpage 142.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking situation
may occur by monitoring how fast the throttle is
released by the driver. The Electronic Brake
Control (EBC) system will prepare the brake system
for a panic stop.
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small amount
of brake pressure to remove any water buildup on
the front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When RBS
is active, there is no notification to the driver and
no driver interaction is required.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce vehicle power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential
(BLD), functions similarly to a limited slip
differential and controls the wheel spin across a
driven axle. If one wheel on a driven axle is
spinning faster than the other, the system will
apply the brake of the spinning wheel. This will
allow more vehicle torque to be applied to the wheel that is not spinning. BLD may remain
enabled even if TCS and the Electronic Stability
Control (ESC) are in reduced modes.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow
the trailer tongue weight recommendations
Úpage 130.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” mode.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there
may not be enough brake pressure to hold
both the vehicle and the trailer on a hill when
the brake pedal is released. In order to avoid
rolling down an incline while resuming accel -
eration, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle.
Also, be certain to place the transmission in
PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.

SAFETY215
This vehicle is equipped with a right front
passenger Occupant Classification System (OCS)
that is designed to provide Passenger Advanced
Front Air Bag output appropriate to the occupant’s
seated weight input, as determined by the OCS.
Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions. The front
air bags will not deploy in all frontal collisions,
including some that may produce substantial
vehicle damage — for example, some pole
collisions, truck underrides, and angle offset
collisions.
On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and damage
by themselves are not good indicators of whether
or not an air bag should have deployed. Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)
detects a collision requiring the front air bags, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air
bags.
The steering wheel hub trim cover and the upper
passenger side of the instrument panel separate
and fold out of the way as the air bags inflate to
their full size. The front air bags fully inflate in less
time than it takes to blink your eyes. The front air
bags then quickly deflate while helping to restrain
the driver and front passenger.
WARNING!
No objects should be placed over or near the
air bag on the instrument panel or steering
wheel because any such objects could cause
harm if the vehicle is in a collision severe
enough to cause the air bag to inflate.
Do not put anything on or around the air bag
covers or attempt to open them manually. You
may damage the air bags and you could be
injured because the air bags may no longer be
functional. The protective covers for the air
bag cushions are designed to open only when
the air bags are inflating.
Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain you
properly. In some collisions, air bags won’t
deploy at all. Always wear your seat belts even
though you have air bags.

Occupant Classification System (OCS) —
Front Passenger Seat
The Occupant Classification System (OCS) is part
of a Federally regulated safety system for this
vehicle. It is designed to provide Passenger
Advanced Front Air Bag output appropriate to the
occupant’s seated weight, as determined by the
OCS.
The Occupant Classification System (OCS) consists
of the following:
Occupant Restraint Controller (ORC)
Occupant Classification Module (OCM) and
Sensor located in the front passenger seat
Air Bag Warning Light Occupant Classification Module (OCM) And Sensor
The Occupant Classification Module (OCM) is
located underneath the front passenger seat. The
Sensor is located beneath the passenger seat
cushion foam. Any weight on the seat will be
sensed by the Sensor. The OCM uses input from
the Sensor to determine the front passenger’s
most probable classification. The OCM
communicates this information to the ORC. The
ORC may reduce the inflation rate of the Passenger
Advanced Front Air Bag deployment based on
occupant classification. In order for the OCS to
operate as designed, it is important for the front
passenger to be seated properly and properly
wearing the seat belt.
The OCS will NOT prevent deployment of the
Passenger Advanced Front Air Bag. The OCS may
reduce the inflation rate of the Passenger
Advanced Front Air Bag if the OCS estimates that:
The front passenger seat is unoccupied or has
very light objects on it; or
The front passenger seat is occupied by a small
passenger, including a child; or
The front passenger seat is occupied by a
rear-facing child restraint; or
The front passenger is not properly seated or his
or her weight is taken off of the seat for a period
of time.
21_RUV_OM_EN_USC_t.book Page 216
SAFETY217
* It is possible for a child to be classified as an
adult, allowing a full-power Passenger Advanced
Front Air Bag deployment. Never allow children to
ride in the front passenger seat and never install a
child restraint system, including a rear-facing child
restraint, in the front passenger seat. The OCS determines the front passenger’s most
probable classification. The OCS estimates the
seated weight on the front passenger seat and
where that weight is located. The OCS
communicates the classification status to the ORC.
The ORC uses the classification to determine
whether the Passenger Advanced Front Air Bag
inflation rate should be adjusted.
In order for the OCS to operate as designed, it is
important for the front passenger to be seated
properly and properly wearing the seat belt.
Properly seated passengers are:
Sitting upright
Facing forward
Sitting in the center of the seat with their feet
comfortably on or near the floor
Sitting with their back against the seatback and
the seatback in an upright position
Seated Properly
Lighter Weight Passengers (Including Small Adults)
When a lighter weight passenger, including a small
adult, occupies the front passenger seat, the OCS
may reduce the inflation rate of the Passenger
Advanced Front Air Bag. This does not mean that
the OCS is working improperly.
Front Passenger Seat Occupant Status Front Passenger Air Bag Output
Rear-facing child restraint Reduced-power deployment
Child, including a child in a forward-facing child restraint or booster seat* Reduced-power deployment OR full-power deployment
Properly seated adult Full-power deployment OR reduced-power deployment
Unoccupied seat Reduced-power deployment
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
Children 12 years or younger should always
ride buckled up in the rear seat of a vehicle
with a rear seat.

218SAFETY
Do not decrease OR increase the front passenger’s
seated weight on the front passenger seat
The front passenger’s seated weight must be
properly positioned on the front passenger seat.
Failure to do so may result in serious injury or
death. The OCS determines the most probable
classification of the occupant that it detects. The
OCS will detect the front passenger’s decreased or
increased seated weight, which may result in an
adjusted inflation rate of the Passenger Advanced
Front Air Bag in a collision. This does not mean that
the OCS is working improperly. Decreasing the
front passenger’s seated weight on the front
passenger seat may result in a reduced-power
deployment of the Passenger Advanced Front Air
Bag. Increasing the front passenger’s seated
weight on the front passenger seat may result in a
full-power deployment of the Passenger Advanced
Front Air Bag.
Examples of improper front passenger seating
include:
The front passenger’s weight is transferred to
another part of the vehicle (like the door, arm
rest or instrument panel).
The front passenger leans forward, sideways, or
turns to face the rear of the vehicle.
The front passenger’s seatback is not in the full
upright position.
The front passenger carries or holds an object
while seated (e.g., backpack, box, etc.).
Objects are lodged under the front
passenger seat.
Objects are lodged between the front
passenger seat and center console.
Accessories that may change the seated weight
on the front passenger seat are attached to the
front passenger seat.
Anything that may decrease or increase the
front passenger’s seated weight.
The OCS determines the front passenger’s most
probable classification. If an occupant in the front
passenger seat is seated improperly, the occupant
may provide an output signal to the OCS that is
different from the occupant’s properly seated
weight input, for example:
Not Seated Properly Not Seated Properly

SAFETY219
(Continued)
Not Seated Properly
The Air Bag Warning Light in the instrument
panel will turn on whenever the OCS is unable to
classify the front passenger seat status. A
malfunction in the OCS may affect the operation of
the air bag system.
If the Air Bag Warning Light does not come on,
or stays on after you start the vehicle, or it comes
on as you drive, take the vehicle to an authorized
dealer for service immediately.
The passenger seat assembly contains critical OCS
components that may affect the Passenger
Advanced Front Air Bag inflation. In order for the
OCS to properly classify the seated weight of a front seat passenger, the OCS components must
function as designed. Do not make any
modifications to the front passenger seat
components, assembly, or to the seat cover. If the
seat, trim cover, or cushion needs service for any
reason, take the vehicle to an authorized dealer.
Only FCA US LLC approved seat accessories may
be used.
The following requirements must be strictly
followed:
Do not modify the front passenger seat
assembly or components in any way.
Do not use prior or future model year seat
covers or cushions not designated by FCA US
LLC for the specific model being repaired.
Always use the correct seat cover and cushion
specified for the vehicle.
Do not replace the seat cover or cushion with an
aftermarket seat cover or cushion.
Do not add a secondary seat cover or mat.
At no time should any Supplemental Restraint
System (SRS) component or SRS related
component or fastener be modified or replaced
with any part except those which are approved
by FCA US LLC.
WARNING!
If a child restraint system, child, small teen
-
ager or adult in the front passenger seat is
seated improperly, the occupant may provide
an output signal to the OCS that is different
from the occupant’s properly seated weight
input. This may result in serious injury or death
in a collision.
Always wear your seat belt and sit properly,
with the seatback in an upright position, your
back against the seatback, sitting upright,
facing forward, in the center of the seat, with
your feet comfortably on or near the floor.
Do not carry or hold any objects (e.g., back -
packs, boxes, etc.) while seated in the front
passenger seat. Holding an object may
provide an output signal to the OCS that is
different than the occupant’s properly seated
weight input, which may result in serious injury
or death in a collision.
Placing an object on the floor under the front
passenger seat may prevent the OCS from
working properly, which may result in serious
injury or death in a collision. Do not place any
objects on the floor under the front passenger
seat.
