2021 RAM CHASSIS CAB steering wheel

STARTING AND OPERATING167
(Continued)
Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering
wheel operate the ACC system.
Adaptive Cruise Control Buttons
Does not always fully recognize
complex driving conditions, which can
result in wrong or missing distance
warnings.

Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for approximately two seconds
in the stop position. At this point, there will
be an “ACC may cancel soon” chime and
warning to the driver. When ACC is
cancelled, the system will release the
brakes and the driver must take over
braking. The system can be resumed when
the target vehicle drives off by releasing
the brake and pushing the resume button
on the steering wheel.

WARNING! (Continued)
You should switch off the ACC system:
When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc -
tion zones).
When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
When towing a trailer up or down steep
slopes.
When circumstances do not allow safe
driving at a constant speed.

172STARTING AND OPERATING
To adjust the distance setting, push the
Distance Button and release. Each time the
button is pushed, the distance setting increases
by one bar (longer). When the farthest distance
is set, pushing the distance button again will
reset to the shortest distance.

If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving
vehicle is detected in the same lane, the
instrument cluster displays the ACC Set With
Target Detected Indicator Light, and the system
adjusts vehicle speed automatically to maintain
the distance setting, regardless of the set speed.

The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary. NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning wil l alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visua l alert “BRAKE” will flash in the
instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking force.
NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously. Overtake Aid
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional
acceleration is triggered when the driver
utilizes the left turn signal and will only be
active when passing on the left hand side.
ACC Operation At Stop
If the ACC system brings your vehicle to a
standstill while following the vehicle in front,
your vehicle will resume motion without any
driver intervention if the vehicle in front starts
moving within two seconds.

21_DPF_OM_EN_USC_t.book Page 172
Trailer Detect — If Equipped
When a trailer is detected, the ACC system
automatically defaults to the longest setting
(four bars). The setting can be overridden by
pushing the Distance Button on the steering
wheel.

STARTING AND OPERATING183
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 into 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.
NOTE:
When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provide
an audible and visual warning to the driver if
removed. The system will cancel if the driver
does not return their hands to the wheel.
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
recommended 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 indica
-
tion 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
recommended that the driver looks over
his/her shoulder when using ParkSense.4

STARTING AND OPERATING185
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 uninten -
tional 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 depar -
ture 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.

186STARTING AND OPERATING
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 Úpage 228.
NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph (180 km/h).

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.).

Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when towing while using a full size spare tire.
Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
For the proper tire replacement procedures.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 406.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause inad -
equate braking and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers
over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
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 diffi -
cult 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 overload your vehicle or trailer. Over -
loading can cause a loss of control, poor
performance or damage to brakes, axle,
engine, transmission, steering, suspension,
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.
