136GETTING TO KNOW YOUR INSTRUMENT PANEL
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.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi -
mately one minute and then remain continu -
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
Anti-Lock Brake (ABS) Warning Light
This warning light monitors the
Anti-Lock Brake System (ABS). The
light will turn on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position
and may stay on for as long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is
required as soon as possible. However, the
conventional brake system will continue to
operate normally, assuming the Brake Warning
Light is not also on.
If the ABS light does not turn on when the igni
-
tion is placed in the ON/RUN or ACC/ON/RUN
position, have the brake system inspected by an
authorized dealer.
Rear Axle Locker Fault Indicator Light — If
Equipped
This warning light will illuminate to
indicate when a rear axle locker fault
has been detected.
Refer to “Axle Locker System — Power
Wagon Models Only (If Equipped)” in “Starting
And Operating” for further information.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established 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 dealer to have your
sensor function checked.

The “ESC OFF Indicator Light” indi -
cates the customer has elected to
have the Electronic Stability Control
(ESC) in a reduced mode.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel
lift by monitoring the driver’s steering wheel
input and the speed of the vehicle. When Elec -
tronic Roll Mitigation (ERM) determines that the
rate of change of the steering wheel angle and
vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM
can only reduce the chance of wheel lift occur -
ring during severe or evasive driving maneu -
vers; it cannot prevent wheel lift due to other
factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
NOTE:
ERM is disabled anytime the ESC is in “Full Off”
mode (if equipped). Refer to “Electronic Stability
Control (ESC)” in this section for a complete
explanation of the available ESC modes.
Hill Descent Control (HDC) — If Equipped
Hill Descent Control (HDC) is intended for low
speed off road driving while in 4L Range. HDC
maintains vehicle speed while descending hills
during various driving situations. HDC controls
vehicle speed by actively controlling the brakes. HDC Has Three States:
1. Off (feature is not enabled and will not acti
-
vate)
2. Enabled (feature is enabled and ready but activation conditions are not met, or driver
is actively overriding with brake or throttle
application)
3. Active (feature is enabled and actively controlling vehicle speed)
Enabling HDC
HDC is enabled by pushing the HDC switch, but
the following conditions must also be met to
enable HDC:Driveline is in 4L Range
Vehicle speed is below 5 mph (8 km/h)
Parking brake is released
Driver door is closed
WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence
the chance that wheel lift or rollover may
occur. ERM cannot prevent all wheel lift or roll
overs, especially those that involve leaving
the roadway or striking objects or other
vehicles. The capabilities of an
ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner
which could jeopardize the user's safety or
the safety of others.

Activating HDC
Once HDC is enabled it will activate automati -
cally if driven down a grade of sufficient magni -
tude. The set speed for HDC is selectable by the
driver, and can be adjusted by using the gear
shift +/-. The following summarizes the HDC set
speeds:
HDC Target Set Speeds
P = No set speed. HDC may be enabled but
will not activate.
R = 0.6 mph (1 km/h)
N = 1.2 mph (2 km/h)
D = 0.6 mph (1 km/h)
1st = 0.6 mph (1 km/h)
2nd = 1.2 mph (2 km/h)
3rd = 1.8 mph (3 km/h)
4th = 2.5 mph (4 km/h)
5th = 3.1 mph (5 km/h)
6th = 3.7 mph (6 km/h)
7th = 4.3 mph (7 km/h)
8th = 5.0 mph (8 km/h)
9th = 5.6 mph (9 km/h) – If Equipped
NOTE:
During HDC the +/- shifter input is used for HDC
target speed selection, but will not affect the
gear chosen by the transmission. When actively
controlling HDC the transmission will shift
appropriately for the driver-selected set speed
and corresponding driving conditions.
Driver Override
The driver may override HDC activation with
throttle or brake application at any time.
Deactivating HDC
HDC will be deactivated but remain available if
any of the following conditions occur:
Driver overrides HDC set speed with throttle
or brake application.
Vehicle speed exceeds 20 mph (32 km/h) but remains below 40 mph (64 km/h).
Vehicle is on a downhill grade of insufficient
magnitude, is on level ground, or is on an
uphill grade.
Vehicle is shifted to PARK. Disabling HDC
HDC will be deactivated and disabled if any of
the following conditions occur:
The driver pushes the HDC switch.
The driveline is shifted out of 4L Range.
The parking brake is applied.
The driver door opens.
The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds.
The vehicle is driven greater than 40 mph
(64 km/h) (HDC exits immediately).
HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the
HDC switch has an LED icon, which offers feed -
back to the driver about the state HDC is in.
The cluster icon and switch lamp will illumi -
nate and remain on solid when HDC is
enabled or activated. This is the normal oper -
ating condition for HDC.
The cluster icon and switch lamp will flash for
several seconds then extinguish when the
driver pushes the HDC switch but enable
conditions are not met.
20_DJD2_OM_EN_USC_t.book Page 150
SAFETY151
The cluster icon and switch lamp will flash for
several seconds then extinguish when HDC
disables due to excess speed.
The cluster icon and switch lamp will flash
when HDC deactivates due to overheated
brakes. The flashing will stop and HDC will
activate again once the brakes have cooled
sufficiently.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) system is designed to
mitigate roll back from a complete stop while on
an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold
the brake pressure for a short period. If the
driver does not apply the throttle before this
time expires, the system will release brake pres -
sure and the vehicle will roll down the hill as
normal. The following conditions must be met in order
for HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The park brake must be off.
The driver door must be closed.
The vehicle must be on a sufficient grade.
The gear selection must match vehicle uphill
direction (i.e., vehicle facing uphill is in
forward gear; vehicle backing uphill is in
REVERSE (R) gear).
HSA will work in REVERSE gear and all
forward gears. The system will not activate if
the transmission is in PARK or NEUTRAL (N).
For vehicles equipped with a manual trans
-
mission, if the clutch is pressed, HSA will
remain active.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descending
hills. The driver must remain attentive to the
driving conditions and is responsible for
maintaining a safe vehicle speed.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA
is not a substitute for active driving
involvement. It is always the driver’s
responsibility to be attentive to distance to
other vehicles, people, and objects, and most
importantly brake operation to ensure safe
operation of the vehicle under all road
conditions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these
warnings can result in a collision or serious
personal injury.

Modes Of Operation
Three selectable modes of operation are avail -
able in the Uconnect System.
Refer to “Uconnect Settings” in “Multimedia”
for further information.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the
BSM system will provide a visual alert in the
appropriate side view mirror based on a
detected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and
audible alerts when a detected object is
present. Whenever an audible alert is
requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/
Chime mode, the BSM system will provide a
visual alert in the appropriate side view mirror
based on a detected object. If the turn signal is
then activated, and it corresponds to an alert
present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn
signal and detected object are present on the
same side at the same time, both the visual and
audible alerts will be issued. In addition to the
audible alert the radio (if on) will also be muted. NOTE:
Whenever an audible alert is requested by the
BSM system, the radio is also muted.
When the system is in RCP, the system shall
respond with both visual and audible alerts
when a detected object is present. Whenever
an audible alert is requested, the radio is also
muted. Turn/hazard signal status is ignored;
the RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will be
no visual or audible alerts from either the BSM
or RCP systems.
NOTE:
The BSM system will store the current operating
mode when the vehicle is shut off. Each time
the vehicle is started the previously stored
mode will be recalled and used.
Trailer Merge Assist
NOTE:
When Trailer Merge Assist is activated, Rear
Cross Path is disabled.
NOTE:
When a trailer with an electric brake is
connected to the vehicle, the instrument cluster
display will provide a menu to allow a selection
of the trailer type. There will be two options
provided: Conventional and Goose/Fifth Wheel.
Goose/Fifth Wheel Trailer is incompatible and
when selected, the BSM system will disable
until the trailer is disconnected. If the wrong
option is selected, the system can be reset by
either disconnecting and reconnecting the
trailer harness connector or disabling then
re-enabling the Blind Spot Monitoring System in
the customer settings in the Uconnect. This will
prompt the trailer selection menu again to allow
for the correct selection.
Trailer Merge Assist is a function of the Blind
Spot Monitoring (BSM) system that extends the
blind spot zone to work while pulling a trailer.
Trailer Merge Assist consists of three sub func
-
tions:Automatic Trailer Detection
Trailer Length Detection

NOTE:
Changes or modifications not expressly
approved by the party responsible for compli -
ance could void the user’s authority to operate
the equipment.Forward Collision Warning (FCW) With
Mitigation — If Equipped
The Forward Collision Warning (FCW) system
provides the driver with audible, visual warnings
(within the instrument cluster display), and may
apply a haptic warning in the form of a brake
jerk, to warn the driver when it detects a poten -
tial frontal collision. The warnings are intended
to provide the driver with enough time to react,
avoid or mitigate the potential collision.
NOTE:
FCW monitors the information from the forward
looking sensors as well as Electronic Brake
Controller (EBC), to calculate the probability of a
forward collision. When the system determines
that a forward collision is probable, the driver
will be provided with audible and visual warn-
ings as well as a possible haptic warning in the
form of a brake jerk.
If the driver does not take action based upon
these progressive warnings, then the system
will provide a limited level of active braking to
help slow the vehicle and mitigate the potential
forward collision. If the driver reacts to the warn -
ings by braking and the system determines that
the driver intends to avoid the collision by
braking but has not applied sufficient brake force, the system will compensate and provide
additional brake force as required. When towing
a trailer, the system will also respond to activate
the trailer brakes (if equipped).
If a FCW with Mitigation event begins at a speed
below 32 mph (52 km/h), the system may
provide the maximum braking possible to miti
-
gate the potential forward collision. If the
Forward Collision Warning with Mitigation event
stops the vehicle completely, the system will
hold the vehicle at standstill for two seconds
and then release the brakes.
FCW Message
20_DJD2_OM_EN_USC_t.book Page 160
SAFETY161
When the system determines a collision with
the vehicle in front of you is no longer probable,
the warning message will be deactivated.
NOTE:
The minimum speed for FCW activation is
3 mph (5 km/h).
The FCW alerts may be triggered on objects
other than vehicles such as guard rails or
sign posts based on the course prediction.
This is expected and is a part of normal FCW
activation and functionality.
It is unsafe to test the FCW system. To
prevent such misuse of the system, after four
Active Braking events within a key cycle, the
Active Braking portion of FCW will be deacti -
vated until the next key cycle.
The FCW system is intended for on-road use
only. If the vehicle is taken off-road, the FCW
system should be deactivated to prevent
unnecessary warnings to the surroundings.
FCW may not react to irrelevant objects such
as overhead objects, ground reflections,
objects not in the path of the vehicle,
stationary objects that are far away, oncoming traffic, or leading vehicles with the
same or higher rate of speed.
“FCW will be disabled like ACC, with the
unavailable screens.
During a FCW event when towing a trailer,
your Electronic Brake system will respond, to
activate the trailer brakes (if equipped).
Turning FCW On or Off
The FCW button is located in the Uconnect
display in the control settings. Refer to “Ucon
-
nect Settings” in “Multimedia” in the Owner's
Manual for further information.
To turn the FCW system on, press the forward
collision button once.
To turn the FCW system off, press the forward
collision button once.
NOTE:
When the FCW is “on”, this allows the system
to warn the driver of a possible collision with
the vehicle in front.
When the FCW is “off” prevents the system
from warning the driver of a possible collision
with the vehicle in front. If the FCW is set to
“off”, “FCW OFF" will be displayed in the
instrument cluster display.
When FCW status is set to “Only Warning”
prevents the system from providing limited
active braking, or additional brake support if
the driver is not braking adequately in the
event of a potential frontal collision.
When FCW status is set to “Warning and
Braking” this allows the system to warn the
driver of a possible collision with the vehicle
in front using audible/visual warnings and it
applies autonomous braking.
The FCW system state is defaulted to “Full
On” from one ignition cycle to the next. If the
system is turned off, it will reset to “Full On”
when the vehicle is restarted.
WARNING!
Forward Collision Warning (FCW) is not
intended to avoid a collision on its own, nor
can FCW detect every type of potential
collision. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.

NOTE:
Changes or modifications not expressly
approved by the party responsible for compli -
ance could void the user’s authority to operate
the equipment.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.
NOTE:
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. In addition, the instrument
cluster will display a graphic showing the pres -
sure values of each tire with the low tire pres -
sure values in a different color, or the Uconnect
radio will display a TPMS message, when this
occurs you must increase the tire pressure to
the recommended cold placard pressure in
order for the TPMS Warning Light to turn off.
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.
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 TPMS Warning Light illumi -
nates, 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 pressures. 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.
