SAFETY FEATURES
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides
increased vehicle stability and brake perfor-
mance under most braking conditions. The
system automatically prevents wheel lock, and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure
that the ABS is working properly each time the
vehicle is started and driven. During this
self-check, you may hear a slight clicking sound
as well as some related motor noises.
ABS is activated during braking when the
system detects one or more wheels begin to
lock. Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic
stops may increase the likelihood of ABS activa-
tion(s). You also may experience the following when
ABS activates:
The ABS motor noise (it may continue to run
for a short time after the stop)
The clicking sound of solenoid valves
Brake pedal pulsations
A slight drop of the brake pedal at the end of
the stop
These are all normal characteristics of ABS.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to inter -
ference caused by improperly installed or
high output radio transmitting equipment.
This interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by
qualified professionals.
Pumping of the Anti-Lock Brakes will
diminish their effectiveness and may lead
to a collision. Pumping makes the stopping
distance longer. Just press firmly on your
brake pedal when you need to slow down or
stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can
it increase braking or steering efficiency
beyond that afforded by the condition of the
vehicle brakes and tires or the traction
afforded.
The ABS cannot prevent collisions,
including those resulting from excessive
speed in turns, following another vehicle
too closely, or hydroplaning.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize
the user’s safety or the safety of others.

ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modifica -
tion may result in degraded ABS performance.
Anti-Lock Brake Warning Light
The yellow “Anti-Lock Brake Warning Light” will
turn on when the ignition is placed in the ON/
RUN mode and may stay on for as long as four
seconds.
If the “Anti-Lock Brake Warning Light” remains
on or comes on while driving, it indicates that
the anti-lock portion of the brake system is not
functioning and that service is required.
However, the conventional brake system will
continue to operate normally if the “Anti-Lock
Brake Warning Light” is on.
If the “Anti-Lock Brake Warning Light” is on, the
brake system should be serviced as soon as
possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning Light”
does not come on when the ignition is placed in
the ON/RUN mode, have the light repaired as
soon as possible.
Electronic Brake Control (EBC) System
Your vehicle is equipped with an advanced Elec -
tronic Brake Control (EBC) system . This system
includes Electronic Brake Force Distribution (EBD), Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Hill Start Assist (HSA),
Traction Control System (TCS), Electronic
Stability Control (ESC), and Electronic Roll Miti
-
gation (ERM). These systems work together to
enhance both vehicle stability and control in
various driving conditions.
Your vehicle may also be equipped with Trailer
Sway Control (TSC) and Hill Descent Control
(HDC).
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to
optimize the vehicle’s braking capability during
emergency braking maneuvers. The system
detects an emergency braking situation by
sensing the rate and amount of brake applica -
tion and then applies optimum pressure to the
brakes. This can help reduce braking distances.
The BAS complements the Anti-Lock Brake
System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive
the benefit of the system, you must apply
continuous braking pressure during the stop-
ping sequence, (do not “pump” the brakes). Do
not reduce brake pedal pressure unless braking
is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red “Brake System Warning Light” will turn
on when the ignition is placed in the ON/RUN
mode and may stay on for as long as four
seconds.
If the “Brake System Warning Light” remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and
that immediate service is required. If the “Brake
System Warning Light” does not come on when
the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
WARNING!
The Brake Assist System (BAS) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road
conditions. BAS cannot prevent collisions,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of
a BAS-equipped vehicle must never be
exploited in a reckless or dangerous manner,
which could jeopardize the user's safety or
the safety of others.

Electronic Brake Force Distribution (EBD)
This function manages the distribution of the
braking torque between the front and rear axles
by limiting braking pressure to the rear axle.
This is done to prevent overslip of the rear
wheels to avoid vehicle instability, and to
prevent the rear axle from entering Anti-Lock
Brake System (ABS) before the front axle.
Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. Electronic Stability Control (ESC)
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to assist in counteracting the oversteer
or understeer condition. Engine power may also
be reduced to help the vehicle maintain the
desired path.
ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel posi -
tion.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will start
to flash as soon as the ESC system becomes
active. The “ESC Activation/Malfunction Indi -
cator Light” also flashes when the TCS is active.
If the “ESC Activation/Malfunction Indicator
Light” begins to flash during acceleration, ease
up on the accelerator and apply as little throttle
as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
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, atten -
tive, and skillful driver can prevent acci -
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reck -
less or dangerous manner which could
jeopardize the user’s safety or the safety of
others.

vehicle speed reaches approximately 6 mph
(10 km/h) or higher and will alert the driver of
vehicles in these areas.
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The Blind Spot Monitoring (BSM) system may
experience drop outs (blinking on and off) of
the side mirror Warning Indicator lamps
when a motorcycle or any small object
remains at the side of the vehicle for
extended periods of time (more than a couple
of seconds).
The vehicle’s taillights, where the radar sensors
are located, must remain free of snow, ice, and
dirt/road contamination so that the BSM
system can function properly. Do not block the
taillights with foreign objects (bumper stickers,
bicycle racks, etc.).
Radar Sensor Locations

If the system detects degraded performance
due to contamination or foreign objects, a
message will warn you of a blocked sensor and
the warning indicators in side view mirrors will
be on. The warning indicators will remain illumi -
nated until blockage clearing conditions are
met. First clear the taillights around the sensors
of the blockage. After removing the blockage,
the following procedure can be used to reset
the system, cycle the ignition from ON to OFF
and then back ON.
If the blockage message is still present after
cycling the ignition and driving in traffic, check
again for a blockage. The BSM system notifies the driver of objects in
the detection zones by illuminating the BSM
warning light located in the outside mirrors in
addition to sounding an audible (chime) alert
and reducing the radio volume. Refer to “Modes
Of Operation” in this section for further informa-
tion.

Warning Light Location

The BSM system monitors the detection zone
from three different entry points (side, rear,
front) while driving to see if an alert is neces -
sary. The BSM system will issue an alert during
these types of zone entries.

20_DJD2_OM_EN_USC_t.book Page 154

156SAFETY
The BSM system will not alert you of objects that
are traveling in the opposite direction of the
vehicle in adjacent lanes.

Opposing Traffic
Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is intended
to aid the driver when backing out of parking
spaces where their vision of oncoming vehicles
may be blocked. Proceed slowly and cautiously
out of the parking space until the rear end of the
vehicle is exposed. The RCP system will then
have a clear view of the cross traffic and if an
oncoming vehicle is detected, alert the driver.
RCP Detection Zones

RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 3 mph (5 km/h), to
objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situa -
tions. NOTE:
In a parking lot situation, oncoming vehicles can
be obscured by vehicles parked on either side.
If the sensors are blocked by other structures or
vehicles, the system will not be able to alert the
driver.
When RCP is on and the vehicle is in REVERSE,
the driver is alerted using both the visual and
audible alarms, including reducing the radio
volume.
WARNING!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so
can result in serious injury or death.
WARNING!
Rear Cross Path Detection (RCP) is not a back
up aid system. It is intended to be used to
help a driver detect an oncoming vehicle in a
parking lot situation. Drivers must be careful
when backing up, even when using RCP.
Always check carefully behind your vehicle,
look behind you, and be sure to check for
pedestrians, animals, other vehicles,
obstructions, and blind spots before backing
up. Failure to do so can result in serious
injury or death.

minimum of five seconds and then display
dashes (- -) in place of the pressure value to indi -
cate which sensor is not being received.
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the “Tire Pres -
sure Monitoring Warning Light” will no longer
flash, and the "SERVICE TPM SYSTEM" message
will no longer display, and a pressure value will
display in place of the dashes. A system fault
can occur due to any of the following:
Signal interference due to electronic devices
or driving next to facilities emitting the same
radio frequencies as the TPM sensors.
Installing aftermarket window tinting that
contains materials that may block radio wave
signals.
Accumulation of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPM
sensors.
A system fault may occur due to an incorrect
TPM sensor location condition. When a system
fault occurs due to an incorrect TPM sensor location, the “Tire Pressure Monitoring Warning
Light” will flash on and off for 75 seconds and
then remain on solid. The system fault will also
sound a chime. In addition, the instrument
cluster will display a “Tire Pressure Temporarily
Unavailable” message in place of the tire pres
-
sure display screen. If the ignition switch is
cycled, this sequence will repeat, providing the
system fault still exists. If the system fault no
longer exists, the “Tire Pressure Monitoring
Warning Light” will no longer flash and the tire
pressure display screen will be displayed
showing the tire pressure values the correct
locations.
Vehicles With Non Matching Full Size Spare Or
Compact Spare
The non matching full size spare or compact
spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the
pressure in the non matching full size spare
or compact spare tire.
If you install the non matching full size spare
or compact spare tire in place of a road tire
that has a pressure below the low-pressure
warning limit, upon the next ignition switch
cycle, the TPM Warning Light and a “LOW
TIRE” message will remain on and a chime will sound. In addition, the graphic in the
instrument cluster will still display a pressure
value in a different color and an “Inflate to
XX” message.
After driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the TPM Warning
Light will flash on and off for 75 seconds and
then remain on solid. In addition, the instru -
ment cluster will display a "SERVICE TPM
SYSTEM" message for a minimum of five
seconds and then display dashes (- -) in place
of the pressure value.
For each subsequent ignition switch cycle, a
chime will sound, the TPM Warning Light will
flash on and off for 75 seconds and then
remain on solid, and the instrument cluster
will display a "SERVICE TPM SYSTEM"
message for a minimum of five seconds and
then display dashes (- -) in place of the pres -
sure value.
Once you repair or replace the original road
tire and reinstall it on the vehicle in place of
the non matching full size spare or compact
spare, the TPMS will update automatically. In
addition, the TPM Warning Light will turn off
and the graphic in the instrument cluster will
display a new pressure value instead of

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 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.
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 except the Mega Cab and
Crew Cab front center seating position have
combination 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.

20_DJD2_OM_EN_USC_t.book Page 173

176SAFETY
4. Position the lap belt so that it is snug and
lies low across your hips, below your
abdomen. To remove slack in the lap belt
portion, pull up on the shoulder belt. To
loosen the lap belt if it is too tight, tilt the
latch plate and pull on the lap belt. A snug
seat belt reduces the risk of sliding under
the seat belt in a collision.

Positioning The Lap Belt

5. Position the shoulder belt across the shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will with -
draw any slack in the shoulder belt.
6. To release the seat belt, push the red button on the buckle. The seat belt will automati -
cally retract to its stowed position. If neces -sary, slide the latch plate down the webbing
to allow the seat belt to retract fully.
Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a twisted
lap/shoulder belt.

1. Position the latch plate as close as
possible to the anchor point.

2. At about 6 to 12 inches (15 to 30 cm) above the latch plate, grasp and twist the seat belt
webbing 180 degrees to create a fold that
begins immediately above the latch plate.
3. Slide the latch plate upward over the folded webbing. The folded webbing must enter
the slot at the top of the latch plate.
4. Continue to slide the latch plate up until it clears the folded webbing and the seat belt
is no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and outboard front passenger
seats, the top of the shoulder belt can be
adjusted upward or downward to position the
seat belt away from your neck. Push or squeeze
the anchorage button to release the anchorage, and move it up or down to the position that
serves you best.

Adjustable Anchorage

As a guide, if you are shorter than average, you
will prefer the shoulder belt anchorage in a
lower position, and if you are taller than
average, you will prefer the shoulder belt
anchorage in a higher position. After you
release the anchorage button, try to move it up
or down to make sure that it is locked in posi -
tion.
NOTE:
The adjustable upper shoulder belt anchorage
is equipped with an Easy Up feature. This
feature allows the shoulder belt anchorage to
be adjusted in the upward position without
pushing or squeezing the release button. To

verify the shoulder belt anchorage is latched,
pull downward on the shoulder belt anchorage
until it is locked into position.First Row Center Seat Belt Operating
Instructions (Regular Cab Only)
The first row center seat belt (Regular Cab only)
features a seat belt with a mini-latch plate and
buckle, which allows the seat belt to detach
from the lower anchor when the seat is folded.
The latch plate and regular latch plate can then
be stored out of the way in the seat for added
convenience to open up utilization of the
storage areas behind the front seats when the
seat is not occupied.

1. Remove the mini-latch plate and regular
latch plate from its stowed position on the
seat.

Connect Mini-Latch To Mini-Buckle Mini-Latch And Mini-Buckle Connected

2. Grasp the mini-latch plate and pull the seat belt over the seat.
3. Route the shoulder belt to the inside of the right head restraint.
4. When the seat belt is long enough to fit, insert the mini-latch plate into the
mini-buckle until you hear a “click.”
5. Sit back in seat. Slide the regular latch plate up the webbing as far as necessary to allow
the seat belt to go around your lap.
6. When the seat belt is long enough to fit, insert the latch plate into the buckle until
you hear a “click.”
WARNING!
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.
Position the shoulder belt across the
shoulder and chest with minimal, if any
slack so that it is comfortable and not
resting on your neck. The retractor will with -
draw any slack in the shoulder belt.
Misadjustment of the seat belt could
reduce the effectiveness of the safety belt
in a crash.
Always make all seat belt height adjust -
ments when the vehicle is stationary.
