SAFETY59
NOTE:
To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow,
sand or gravel, it may be desirable to switch to
the “Partial Off” mode by pushing the “ESC OFF”
switch. Once the situation requiring ESC to be
switched to the “Partial Off” mode is overcome,
turn ESC back on by momentarily pushing the
“ESC OFF” switch. This may be done while the
vehicle is in motion.

Hill Start Assist (HSA)
The Hill Start Assist (HSA) system is designed to
assist the driver when starting a vehicle from a stop
on a hill. HSA will maintain the level of brake pres -
sure the driver applied for a short period of time
after the driver takes their foot off of the brake
pedal. If the driver does not apply the throttle during
this short period of time, the system will release
brake pressure and the vehicle will roll down the hill.
The system will release brake pressure in proportion
to the amount of throttle applied as the vehicle
starts to move in the intended direction of travel.
HSA Activation Criteria
The following criteria must be met in order for HSA
to activate:
Vehicle must be stopped
Vehicle must be on a 6% (approximate) grade or
greater hill
Gear selection matches vehicl e uphill direction
(i.e., vehicle facing uphill is in forward gear;
vehicle backing uphill is in REVERSE (R) gear)
HSA will work in REVERSE and all forward gears
when the activation criteria have been met. The
system will not activate if the vehicle is placed in
NEUTRAL (N) or PARK (P).

Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Traction Control System (TCS)
The Traction Control System (TCS) monitors the
amount of wheel spin of each of the driven
wheels. If wheel spin is detected, brake pressure
is applied to the slipping wheel(s) and engine
power is reduced, to provide enhanced accelera -
tion and stability. A feature of the TCS system,
Brake Limited Differential (BLD), functions
similar 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 engine torque to be
applied to the wheel that is not spinning. This
feature remains active even if the ESC is in the
“Partial Off” mode.

WARNING!
There may be situations on minor hills with
a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight
rolling may occur. This could cause a
collision with another vehicle or object.
Always remember the driver is responsible
for braking the vehicle.
WARNING!
If you use a trailer brake controller with
your trailer, the trailer brakes may be acti -
vated 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 accelera -
tion, 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 trans -
mission in PARK.
Failure to follow these warnings can result
in a collision or serious personal injury.
WARNING!

SAFETY61

The ESC Activation/Malfunction Indicator Light
(in the instrument cluster) will start to flash as
soon as the tires lose traction and the wheels
begin to spin. This indicates that the TCS is
active. If the indicator light flashes during accel -
eration, ease up on the accelerator and apply as
little throttle as possible. Be sure to adapt your
speed and driving to the prevailing road condi -
tions, and do not switch off the ESC or TCS.

Trailer Sway Control (TSC) — If Equipped
Trailer Sway Control (TSC) uses sensors in the
vehicle to recognize an excessively swaying
trailer and will take the appropriate actions to
attempt to stop the sway. The system may reduce engine power and apply the brake of
the appropriate wheel(s) to counteract the
sway of the trailer. TSC will become active
automatically once an excessively swaying
trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda
-
tions. Refer to “Trailer Towing” in “Starting And
Operating” for further information.
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.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS)
will warn the driver of a low tire pressure based
on the vehicle recommended cold placard pres -
sure.
The tire pressure will vary with temperature by
about 1 psi (7 kPa) for every 12°F (6.5°C). This
means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after a three hour period. The
cold tire inflation pressure must not exceed the
maximum inflation pressure molded into the
tire sidewall. Refer to “Tires” in “Servicing And
Maintenance” for information on how to prop -
erly inflate the vehicle’s tires. The tire pressure
will also increase as the vehicle is driven - this is
normal and there should be no adjustment for
this increased pressure.
WARNING!
The TCS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase the traction afforded.
The TCS cannot prevent collisions,
including those resulting from excessive
speed in turns, or hydroplaning.
The capabilities of a TCS-equipped vehicle
must never be exploited in a reckless or
dangerous manner, which could jeopardize
the user's safety or the safety of others.
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.

62SAFETY
(Continued)
The TPMS will warn the driver of a low tire pres -
sure if the tire pressure falls below the low-pres -
sure warning limit for any reason, including low
temperature effects and natural pressure loss
through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at
or above the recommended cold placard pres -
sure. Once the low tire pressure warning (TPMS
Warning Light) illuminates, you must increase
the tire pressure to the recommended cold
placard pressure in order for the TPMS Warning
Light to turn off. The system will automatically
update and the TPMS Warning Light will turn off
once the system receives the updated tire pres -
sures. The vehicle may need to be driven for up
to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.
For example, your vehicle may have a recom
-
mended cold (parked for more than three
hours) placard pressure of 30 psi (207 kPa).
If the ambient temperature is 68°F (20°C)
and the measured tire pressure is 27 psi
(186 kPa), a temperature drop to 20°F
(-7°C) will decrease the tire pressure to
approximately 23 psi (158 kPa). This tire
pressure is sufficiently low enough to turn on
the TPMS Warning Light. Driving the vehicle
may cause the tire pressure to rise to approx -
imately 27 psi (186 kPa), but the TPMS
Warning Light will still be on. In this situation,
the TPMS Warning Light will turn off only after
the tires are inflated to the vehicle’s recom -
mended cold placard pressure value.
NOTE:
The TPMS is not intended to replace normal
tire care and maintenance or to provide
warning of a tire failure or condition.
The TPMS should not be used as a tire pres
-
sure gauge while adjusting your tire pressure.
Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
CAUTION!
The TPMS has been optimized for the orig -
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished 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 pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.
CAUTION!
(Continued)
20_VF_OM_EN_US_t.book Page 62

SAFETY63
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsi -
bility to maintain correct tire pressure using
an accurate tire pressure gauge, even if
under-inflation has not reached the level to
trigger illumination of the TPMS Warning
Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
Base System
This is the TPMS warning indicator
located in the instrument cluster.
The TPMS uses wireless technology
with wheel rim mounted electronic
sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to
the Receiver Module.
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle
regularly and to maintain the proper pressure.
The TPMS consists of the following components:

Receiver Module
Four Tire Pressure Monitoring sensors
Tire Pressure Monitoring System Warning
Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring System Warning
Light will illuminate in the instrument cluster, an
audible chime will be activated, and the “Check
tire pressure” message will display when one or
more of the four active road tire pressures are
low. Should this occur, you should stop as soon
as possible, check the inflation pressure of
each tire on your vehicle, and inflate each tire to
the vehicle’s recommended cold placard pres
-
sure value. The system will automatically
update and the Tire Pressure Monitoring Light
will extinguish once the updated tire pressures
have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and
remain on solid when a system fault is detected,
an audible chime will be activated and the “Tire
Pressure Monitoring Unavailable” message will
display. If the ignition key is cycled, this
sequence will repeat providing the system fault
still exists. The TPMS Warning Light will turn off
when the fault condition no longer exists. A
system fault can occur with any of the following
scenarios:
Jamming due to electronic devices or driving
next to facilities emitting the same radio
frequencies as the TPM sensors
Installing some form of aftermarket window
tinting that affects radio wave signals
Snow or ice around the wheels or wheel
housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPM
sensors

64SAFETY
NOTE:
Your vehicle is equipped with a regular size
spare wheel.
1. The spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the
pressure in the spare tire.
2. If a spare tire not equipped with the Tire Pressure Monitoring sensor is used, the
TPMS Warning Light will turn on, flashing for
75 seconds and then remaining solid for
each subsequent ignition key cycle.
3. Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the spare tire, the TPMS will update auto -
matically and the Tire Pressure Monitoring
Light will extinguish once the updated tire
pressures have been received. The vehicle
may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information.
NOTE:
For correct Tire Pressure Monitoring behavior,
please wait for about 20 minutes in key-off
during each tire substitution.General Information

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
Occupant Restraint Systems Features
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air
Bags
Child Restraints

20_VF_OM_EN_US_t.book Page 64

66SAFETY
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 igni -
tion switch is in the AVV/START or MAR/RUN
position. Initial Indication
If the driver is unbuckled when the ignition
switch is first in the AVV/START or MAR/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 AVV/START or MAR/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 recom
-
mended 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 recom -
mend deactivating BeltAlert.

(Continued)
(Continued)
(Continued)
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.
Lap/Shoulder Belts
All seating positions in your vehicle are
equipped with lap/shoulder belts.
The seat belt webbing retractor will lock only
during very sudden stops or collisions. This
feature allows the shoulder part of the seat belt
to move freely with you under normal condi -
tions. However, in a collision the seat belt will
lock and reduce your risk of striking the inside
of the vehicle or being thrown out of the vehicle.
WARNING!
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, the air bags
won’t deploy at all. Always wear your seat
belt even though you have air bags.
In a collision, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the inte -
rior of your vehicle or other passengers, or
you can be thrown out of the vehicle. Always
be sure you and others in your vehicle are
buckled up properly.
It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely
to be seriously injured or killed.
Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
Be sure everyone in your vehicle is in a seat
and using a seat belt properly. Occupants,
including the driver, should always wear
their seat belts whether or not an air bag is
also provided at their seating position to
minimize the risk of severe injury or death
in the event of a crash.
WARNING!
(Continued)

Wearing your seat belt incorrectly could
make your injuries in a collision much
worse. You might suffer internal injuries, or
you could even slide out of the seat belt.
Follow these instructions to wear your seat
belt safely and to keep your passengers
safe, too.
Two people should never be belted into a
single seat belt. People belted together can
crash into one another in a collision, hurting
one another badly. Never use a lap/
shoulder belt or a lap belt for more than one
person, no matter what their size.
WARNING!
A lap belt worn too high can increase the
risk of injury in a collision. The seat belt
forces won’t be at the strong hip and pelvic
bones, but across your abdomen. Always
wear the lap part of your seat belt as low as
possible and keep it snug.
