(Continued)
When Brake Service Mode work is complete, the following
steps must be followed to reset the parking brake system
to normal operation:

Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB Switch.
NOTE:A dedicated message will appear in the instrument cluster
display if Brake Service Mode cannot be deactivated.
AUTOMATIC TRANSMISSION
You must press and hold the brake pedal while shifting out
of PARK.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.
WARNING!
Never use the PARK (P) position as a substitute for
the parking brake. Always apply the parking brake
fully when exiting the vehicle to guard against vehicle
movement and possible injury or damage.
Your vehicle could move and injure you and others if
it is not in PARK. Check by trying to move the gear
selector out of PARK with the brake pedal released.
Make sure the transmission is in PARK before exiting
the vehicle.
 It is dangerous to shift out of PARK or NEUTRAL (N) if
the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the
vehicle could accelerate quickly forward or in
reverse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.
 The vehicle may not engage a newly selected gear
when shifting between PARK, REVERSE (R), or
DRIVE (D) if the vehicle is moving while shifting.
 Unintended movement of a vehicle could injure
those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF position, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.
 When leaving the vehicle, always make sure the igni -
tion is in the OFF position, remove the key fob from
the vehicle, and lock the vehicle.
WARNING!
 Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
transmission gear selector.
 Do not leave the key fob in or near the vehicle (or in
a location accessible to children), and do not leave
the ignition in the ON/RUN position. A child could
operate power windows, other controls, or move the
vehicle.
CAUTION!
Damage to the transmission may occur if the following
precautions are not observed:
Shift into or out of PARK or REVERSE only after the
vehicle has come to a complete stop.
 Do not shift between PARK, REVERSE, NEUTRAL, or
DRIVE when the engine is above idle speed.
 Before shifting into any gear, make sure your foot is
firmly pressing the brake pedal.
WARNING!

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 ensure 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.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 120.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its "loaded and
ready for operation" condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 120.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
WARNING!
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.
Overloading can shorten the life of your vehicle.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.

STARTING AND OPERATING123
(Continued)
TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight stamped on
your trailer hitch.

Weight Distribution

Consider the following items when computing the weight
on the front/rear axles of the vehicle:
The trailer tongue weight.
 The weight of any other type of cargo or equipment 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 authorized dealer-installed
options, must be considered as part of the total load on
your vehicle. Refer to the Tire And Loading Information
Placard located on the driver’s door pillar for the
maximum combined weight of occupants and cargo for
your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended.
Perform the maintenance listed in Scheduled Servicing
and the proper maintenance intervals
Úpage 223. 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 over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, 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.
 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

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your vehicle
are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
 Seat Belt Systems
 Supplemental Restraint Systems (SRS) Air Bags
 Child Restraints
Some of the safety features described in this section may
be standard equipment on some models, or may be
optional equipment on others. If you are not sure, ask an
authorized dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
Here are some simple steps you can take to minimize the
risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride buckled up in the rear seat of a vehicle with a rear
seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured in the appropriate child
restraint or belt-positioning booster seat in a rear
seating position
Úpage 188.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the front passenger seat,
move the seat as far back as possible and use the
proper child restraint
Úpage 188.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that you are using it
properly.
6. All occupants should always wear their lap and shoulder belts properly. 7. The driver and front passenger seats should be
moved back as far as practical to allow the front air
bags room to inflate.
8. Do not lean against the door or window. If your vehicle has side air bags, and deployment occurs, the side air
bags will inflate forcefully into the space between
occupants and the door and occupants could be
injured.
9. If the air bag system in this vehicle needs to be modified to accommodate a disabled person, see
Úpage 270 for customer service contact
information.
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.

SEAT BELT SYSTEMS
Buckle up even though you are an excellent driver, even
on short trips. Someone on the road may be a poor driver
and could cause a collision that includes you. This can
happen far away from home or on your own street.
Research has shown that seat belts save lives, and they
can reduce the seriousness of injuries in a collision. Some
of the worst injuries happen when people are thrown from
the vehicle. Seat belts reduce the possibility of ejection
and the risk of injury caused by striking the inside of the
vehicle. Everyone in a motor vehicle should be belted at
all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver And Passenger BeltAlert — If Equipped
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The
BeltAlert feature is active whenever the ignition switch is
in the START or ON/RUN position. Initial Indication
If the driver is unbuckled when the ignition switch is first in
the START or ON/RUN position, a chime will signal for a
few seconds. If the driver or outboard front seat passenger
(if equipped with outboard front passenger seat BeltAlert)
is unbuckled when the ignition switch is first in the START
or ON/RUN position the Seat Belt Reminder Light will turn
on and remain on until both outboard front seat belts are
buckled. The outboard front passenger seat BeltAlert is
not active when an outboard front passenger seat is
unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when the
vehicle is moving above a specified vehicle speed range
and the driver or outboard front seat passenger is
unbuckled (if equipped with outboard front passenger
seat BeltAlert) (the outboard front passenger seat
BeltAlert is not active when the outboard front passenger
seat is unoccupied). The BeltAlert warning sequence
starts by blinking the Seat Belt Reminder Light and
sounding an intermittent chime. Once the BeltAlert
warning sequence has completed, the Seat Belt Reminder
Light will remain on until the seat belts are buckled. The
BeltAlert warning sequence may repeat based on vehicle
speed until the driver and occupied outboard front seat
passenger seat belts are buckled. The driver should
instruct all occupants to buckle their seat belts.Change Of Status
If the driver or outboard front seat passenger (if equipped
with outboard front passenger seat BeltAlert) unbuckles
their seat belt while the vehicle is traveling, the BeltAlert
warning sequence will begin until the seat belts are
buckled again.
The outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.
BeltAlert may be triggered when an animal or other items
are placed on the outboard front passenger seat or when
the seat is folded flat (if equipped). It is recommended that
pets be restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat belts,
and cargo is properly stowed.
BeltAlert can be activated or deactivated by an authorized
dealer. FCA US LLC does not recommend deactivating
BeltAlert.
NOTE:If BeltAlert has been deactivated and the driver or
outboard front seat passenger (if equipped with outboard
front passenger seat BeltAlert) is unbuckled the Seat Belt
Reminder Light will turn on and remain on until the driver
and outboard front seat passenger seat belts are buckled.

Seat Belts And Pregnant Women

Seat Belts And Pregnant Women

Seat belts must be worn by all occupants including
pregnant women: the risk of injury in the event of an
accident is reduced for the mother and the unborn child if
they are wearing a seat belt.
Position the lap belt snug and low below the abdomen and
across the strong bones of the hips. Place the shoulder
belt across the chest and away from the neck. Never place
the shoulder belt behind the back or under the arm.
Seat Belt Extender
If a seat belt is not long enough to fit properly, even when
the webbing is fully extended and the adjustable upper
shoulder belt anchorage (if equipped) is in its lowest
position, an authorized dealer can provide you with a Seat
Belt Extender. The Seat Belt Extender should be used only
if the existing seat belt is not long enough. When the Seat
Belt Extender is not required for a different occupant, it
must be removed.
Seat Belt Pretensioner
The front outboard seat belt system is equipped with
pretensioning devices that are designed to remove slack
from the seat belt in the event of a collision. These devices
may improve the performance of the seat belt by removing
slack from the seat belt early in a collision. Pretensioners
work for all size occupants, including those in child
restraints.
NOTE:These devices are not a substitute for proper seat belt
placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Restraint
Controller (ORC). Like the air bags, the pretensioners are
single use items. A deployed pretensioner or a deployed
air bag must be replaced immediately.
Energy Management Feature
The front outboard seat belt system is equipped with an
Energy Management feature that may help further reduce
the risk of injury in the event of a collision. The seat belt
system has a retractor assembly that is designed to
release webbing in a controlled manner.
Switchable Automatic Locking
Retractors (ALR)
The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking Retractor
(ALR) which is used to secure a child restraint system
Úpage 196.
The figure provided illustrates the locking feature for each
seating position.

Switchable Automatic Locking Retractor (ALR) Locations

WARNING!
 ONLY use a Seat Belt Extender if it is physically
required in order to properly fit the original seat belt
system. DO NOT USE the Seat Belt Extender if, when
worn, the distance between the front edge of the
Seat Belt Extender buckle and the center of the occu -
pant’s body is LESS than 6 inches.
 Using a Seat Belt Extender when not needed can
increase the risk of serious injury or death in a colli-
sion. Only use the Seat Belt Extender when the lap
belt is not long enough and only use in the recom -
mended seating positions. Remove and store the
Seat Belt Extender when not needed.
