156STARTING AND OPERATING
(Continued)
ParkSense system might not detect an obstacle
behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of the fascia/bumper.
Use the ParkSense switch to turn the ParkSense
system off if obstacles such as bicycle carriers,
trailer hitches, etc. are placed within 18 inches
(45 cm) of the rear fascia/bumper. Failure to do
so can result in the system misinterpreting a
close obstacle as a sensor problem, causing the
“Front/Rear ParkSense Unavailable Service
Required” message to be appear in the instru
-
ment cluster display.
LANESENSE — IF EQUIPPED
LANESENSE OPERATION
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). It uses a forward looking camera to
detect lane markings and measure vehicle
position within the lane boundaries.
When both lane markings are detected and the
driver drifts out of the lane (no turn signal has been
applied) OR the driver departs the lane on the
opposite side of the applied turn signal (if the left
turn signal is applied and the vehicle departs to the
right), the LaneSense system provides a haptic
warning in the form of torque applied to the
steering wheel, as well as a visual warning in the
instrument cluster display to prompt the driver to
remain within the lane boundaries.
The driver may manually override the haptic
warning by applying torque to the steering wheel at
any time.
When only a single lane marking is detected and
the driver drifts across that lane marking (no turn
signal applied), the LaneSense system provides a
visual warning through the instrument cluster
display to prompt the driver to remain within the
lane.
When only a single lane marking is detected, a
haptic (torque) warning will not be provided.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. 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. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.
Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be disconnected from the vehicle
when the vehicle is not used for towing.
Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch ball
will be much closer to the obstacle than the
rear fascia when the vehicle sounds the
continuous tone. Also, the sensors could
detect the ball mount and hitch ball assembly,
depending on its size and shape, giving a false
indication that an obstacle is behind the
vehicle.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle, including
small obstacles. Parking curbs might be
temporarily detected or not detected at all.
Obstacles located above or below the sensors
will not be detected when they are in close
proximity.
The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom -
mended that the driver looks over his/her
shoulder when using ParkSense.
WARNING!

158STARTING AND OPERATING
Left Lane Departure — Both Lane Lines Detected
When the LaneSense system is on, and both the
lane markings have been detected, the system
is "armed" to provide visual warnings in the
instrument cluster display and a torque warning
in the steering wheel if an unintentional lane
departure occurs. The lane lines turn from gray
to white and the LaneSense telltale is solid
green.

Lanes Sensed (White Lines) With Green Telltale

When the LaneSense system senses a lane drift
situation, the left lane line turns solid yellow.
The LaneSense telltale changes from solid
green to solid yellow. At this time torque is
applied to the steering wheel in the opposite
direction of the lane boundary. For example: If approaching the left side of the
lane the steering wheel will turn to the right.

Lane Approached (Solid Yellow Lane Line) With Solid Yellow Telltale

When the LaneSense system senses the lane
has been approached and is in a lane departure
situation, the left lane line flashes yellow (on/
off). The LaneSense telltale changes from
solid yellow to flashing yellow. At this time
torque is applied to the steering wheel in the
opposite direction of the lane boundary. For example: If approaching the left side of the
lane the steering wheel will turn to the right.

Lane Crossed (Flashing Yellow Lane Line) With Flashing Yellow Telltale
NOTE:The LaneSense system operates with similar
behavior for a right lane departure.
CHANGING LANESENSE STATUS
The LaneSense system has settings to adjust the
intensity (Low/Medium/High) of the torque
warning and the warning zone sensitivity (Early/
Medium/Late) that you can configure through the
Uconnect system Ú page 191.
NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).

22_DPF_OM_EN_USC_t.book Page 158

STARTING AND OPERATING159
Use of the turn signal suppresses the warnings.
The system will not apply torque to the steering
wheel whenever a safety system engages
(Anti-Lock Brakes, Traction Control System,
Electronic Stability Control, Forward Collision
Warning, etc.).
PARKVIEW REAR BACK UP CAMERA
The ParkView Rear Back Up Camera allows you to
see an on-screen image of the rear surroundings of
your vehicle whenever the gear selector is put into
REVERSE. The image will be displayed on the
Uconnect display along with a caution note to
“Check Entire Surroundings” across the top of the
screen. After five seconds this note will disappear.
The ParkView Camera is located in the center of
the tailgate handle.
NOTE:For the 3500, 4500, and 5500 Chassis Cab
vehicles, the Rear Backup Camera is shipped
loose and not installed. Please refer to the Ram
Body Builder’s Guide for more information.
Manual Activation Of The Rear View
Camera:

1. Press the "Controls" button located on the bottom of the Uconnect display.

2. Press the "Back Up Camera" icon to turn the Rear View Camera system on. When the vehicle is shifted out of REVERSE (with

exited and the previous screen appears. When the
vehicle is shifted out of REVERSE (with camera
delay turned on), the camera image will continue to
be displayed for up to 10 seconds unless the
following conditions occur: The vehicle speed
exceeds 8 mph (13 km/h), the vehicle is shifted
into PARK, the vehicle’s ignition is placed in the
OFF position, or the user presses image defeat “X”
to exit out of the camera video display.
Whenever the Rear View Camera image is
activated through the "Backup Camera" button in
the Controls menu, and the vehicle speed is
greater than, or equal to, 8 mph (13 km/h), a
display timer for the image is initiated. The image
will continue to be displayed until the display timer
exceeds 10 seconds.NOTE:
If the vehicle speed remains below 8 mph
(13 km/h), the Rear View Camera image will be
displayed continuously until deactivated via the
touchscreen button "X", the transmission is
shifted into PARK, or the ignition is placed in the
OFF position.
The touchscreen button "X" to disable display of
the camera image is made available ONLY when
the vehicle is not in REVERSE.

Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS 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 ABS 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 ABS Warning Light is on.
If the ABS Warning Light is on, the brake system
should be serviced as soon as possible to restore
the benefits of anti-lock brakes. If the ABS 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)
S
YSTEM
Your vehicle is equipped with an advanced
Electronic Brake Control (EBC) system. This system
includes Anti-Lock Brake System (ABS), Brake
Assist System (BAS), Electronic Brake Force
Distribution (EBD), Hill Start Assist (HSA),
Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), and Traction Control
System (TCS). 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 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 application 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 stopping
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.
Electronic Brake Force Distribution (EBD)
EBD 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 ABS before the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When 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 occurring during
severe or evasive driving maneuvers; it cannot
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 pre
-
vailing road conditions. BAS cannot prevent colli -
sions, 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 jeop -
ardize the user's safety or the safety of others.

ESC Operating Modes
Depending upon model and mode of operation, the
ESC system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC
system. Whenever the vehicle is started, the ESC
system will be in this mode. This mode should be
used for most driving conditions. Alternate ESC
modes should only be used for specific reasons as
noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes
stuck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily push
the ESC OFF button and the ESC OFF Indicator
Light will illuminate. To turn the ESC on again,
momentarily push the ESC OFF button and the ESC
OFF Indicator Light will turn off.
NOTE:For vehicles with multiple partial ESC modes, the
push and release of the button will toggle the ESC
modes. Multiple attempts may be required to
return to "ESC On" mode. Full Off — If Equipped
This mode is intended for off-highway or off-road
use only and should not be used on any public
roadways. In this mode, TCS and ESC features are
turned off. To enter the “Full Off” mode, push and
hold the ESC OFF button for five seconds while the
vehicle is stopped with the engine running. After
five seconds, a chime will sound, the ESC OFF
Indicator Light will illuminate, and the “ESC OFF”
message will display in the instrument cluster. To
turn ESC on again, momentarily push the ESC OFF
button.
NOTE:The system may switch from ESC “Full Off” to
“Partial Off” mode when the vehicle exceeds a
predetermined speed. When the vehicle speed
slows below the predetermined speed the system
will return to ESC “Full Off”.
ESC modes may also be affected by drive modes (if
equipped).WARNING!
When in “Partial Off” mode, the TCS function
-
ality of ESC, except for the limited slip feature
described in the TCS section, has been
disabled and the ESC OFF Indicator Light will
be illuminated. When in “Partial Off” mode,
the engine power reduction feature of TCS is
disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered
by the ESC system is unavailable. In an emer -
gency evasive maneuver, the ESC system will
not engage to assist in maintaining stability.
ESC “Full Off” mode is intended for
off-highway or off-road use only.
The 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 condi -
tions. ESC cannot prevent all accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent collisions.

Jack Warning Label

1. If equipped, remove the spare wheel and tools from storage.

2. Using the lug wrench, loosen, but do not remove, the lug nuts by turning them counter -
clockwise one turn while the wheel is still on
the ground.
3. When changing the front wheel, place the jack under the axle as close to the tire as possible.
Front Jacking Locations

When changing a rear wheel, securely place
the jack under the sway bar bracket (unless
both tires are flat on one side, then place jack
under shock bracket) facing forward in vehicle.

Rear Jacking Location
Before raising the wheel off the ground, make
sure that the jack will not damage surrounding
truck parts and adjust the jack position as re
-
quired.
4. Raise the vehicle until the wheel just clears the surface.
5. Remove the lug nuts and pull the wheel off. For Single Rear-Wheel (SRW) models, Install the
spare wheel and lug nuts with the cone shaped
end of the nuts toward the wheel. For Dual
Rear-Wheel (DRW) models, the lug nuts are a
two-piece assembly with a flat face. Lightly
tighten the nuts. To avoid risk of forcing the
vehicle off the jack, do not fully tighten the
nuts until the vehicle has been lowered.
6. Using the lug wrench, finish tightening the nuts using a crisscross pattern Ú page 397. If in
doubt about the correct tightness, have them
checked with a torque wrench by an
authorized dealer or at a service station.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the
Jacking Instructions for this vehicle.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off the
jack and hurt someone near it. Raise the vehicle
only enough to remove the tire.

318IN CASE OF EMERGENCY
7. Install wheel center cap (if equipped) and remove wheel blocks. Do not install chrome or
aluminum wheel center caps on the spare
wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. Stow the replaced tire and tools as previously
described.
9. Adjust the tire pressure when possible.
10. After 25 miles (40 km), check the lug nut torque Ú page 397 with a torque wrench to
ensure that all lug nuts are properly seated
against the wheel.
Dual Rear Wheels
Slots in the wheels will assist in properly orienting
the inner and outer wheels. Align these slots when
assembling the wheels for best access to the tire
valve on the inner wheel. The tires of both dual
wheels must be completely off the ground when
tightening to ensure wheel centering and
maximum wheel clamping. Dual wheel models require a special heavy-duty lug
nut tightening adapter (included with the vehicle)
to correctly tighten the lug nuts. Also, when it is
necessary to remove and install dual rear wheels,
use a proper vehicle lifting device.
NOTE:When installing a spare tire (if equipped) as part of
a dual rear wheel end combination, the tire
diameter of the two individual tires must be
compared. If there is a significant difference, the
larger tire should be installed in a front location.
The correct direction of rotation for dual tire instal
-
lations must also be observed.
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque wheel
stud nuts to specifications at each lubrication
interval Ú page 397.
Wheel Nuts
All wheel nuts should be tightened occasionally to
eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels becoming
elongated. This is especially important during the
first few hundred miles/kilometers of operation to
allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the
wheel. The wheel nuts should then be tightened to
recommended torque. Tighten the wheel nuts to
final torque in increments. Progress around the
bolt circle, tightening the wheel nut opposite to the wheel nut just previously tightened until final
torque is achieved Ú

I
F EQUIPPED
The hub caps must be removed before raising the
vehicle off the ground.
For 3500 Single Rear-Wheel (SRW) models, use
the flat end of the lug wrench to hook and pull off
the hub cap. Find the opening in the hub cap,
insert the lug wrench, and pull off the cap. If you
need to pry against the wheel, protect the wheel
surface.
WARNING!
A loose tire or jack thrown forward in a collision
or hard stop, could endanger the occupants of
the vehicle. Always stow the jack parts and the
spare tire in the places provided.
CAUTION!
Use extreme caution when removing the front
and rear wheel covers. Damage can occur to the
center cap and/or the wheel if screwdriver type
tools are used. A pulling motion, not a pry off
motion, is recommended to remove the caps.

VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
instrument panel, visible through the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off),
the brakes will still function. However, you will
experience a substantial increase in braking effort
to stop the vehicle. If either the front or rear hydraulic system loses
normal braking capability, the remaining system
will still function with some loss of overall braking
effectiveness. This will be evident by increased
pedal travel during application, greater pedal force
required to slow or stop, and activation of the
Brake Warning Light and/or the ABS Warning Light
during brake use.
HYDRAULIC BRAKE ASSIST —
I
F EQUIPPED
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the power
steering system. You may experience some
clicking or hissing noises from the hydro-boost
system during hard braking conditions.
NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
