2022 RAM 1500 brakes

192STARTING AND OPERATING

PARKSENSE ACTIVE PARK ASSIST SYSTEM —
IF EQUIPPED

The ParkSense Active Park Assist system is
intended to assist the driver during parallel and
perpendicular parking maneuvers by identifying a
proper parking space, providing audible/visual
instructions through the instrument cluster
display, and controlling the steering wheel. The
ParkSense Active Park Assist system is defined as
“semi-automatic” since the driver maintains
control of the accelerator, gear selector and brakes. Depending on the driver's parking
maneuver selection, the ParkSense Active Park
Assist system is capable of maneuvering a vehicle
into a parallel or a perpendicular parking space on
either side (i.e., driver side or passenger side).
NOTE:
The driver is always responsible for controlling
the vehicle, responsible for any surrounding
objects, and must intervene as required.
The system is provided to assist the driver and
not to substitute the driver.
During a semi-automatic maneuver, if the driver
touches the steering wheel after being
instructed to remove their hands from the
steering wheel, the system will cancel, and the
driver will be required to manually complete the
parking maneuver.
The system may not work in all conditions (e.g.
environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space
that has surfaces that will absorb the ultrasonic
sensor waves).
New vehicles from the dealership must have at
least 30 miles (48 km) accumulated before the
ParkSense Active Park Assist system is fully cali
-
brated and performs accurately. This is due to
the system’s dynamic vehicle calibration to
improve the performance of the feature.
The driver must control the vehicle’s brakes.
The automatic emergency braking feature is
NOT intended to substitute for the driver during
REVERSE maneuvers.
ENABLING AND DISABLING THE
P
ARKSENSE ACTIVE PARK ASSIST
S
YSTEM
The ParkSense Active Park Assist system
can be enabled and disabled with the
ParkSense Active Park Assist switch,
located on the switch panel below the
Uconnect display.
NOTE:If your vehicle is equipped with a 12-inch Uconnect
display, the ParkSense Active Park Assist switch is
located above the display.
To enable or disable the ParkSense Active Park
Assist system, push the ParkSense Active Park
Assist switch once (LED turns on). Pushing the
switch a second time will disable the system
(LED turns off).
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.

198STARTING AND OPERATING
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 Sensed (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 Approached (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 of the torque warning and the warning
zone sensitivity (Early/Medium/Late) that you can
configure through the Uconnect system
Úpage 234.
NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).
The warnings are disabled with use of the
turn signal.
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.).

212STARTING AND OPERATING
TIRE SIZE
The tire size on the Vehicle Certification Label
represents the actual tire size on your vehicle.
Replacement tires must be equal to the load
capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire
size listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full Gross
Axle Weight Rating (GAWR).
CURB WEIGHT
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with no
occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
LOADING
The actual total weight and the weight of the front
and rear of your vehicle at the ground can best be
determined by weighing it when it is loaded and
ready for operation.
The entire vehicle should first be weighed on a
commercial scale to insure that the Gross Vehicle
Weight Rating (GVWR) has not been exceeded. The
weight on the front and rear of the vehicle should
then be determined separately to be sure that the
load is properly distributed over the front and rear
axle. Weighing the vehicle may show that the Gross
Axle Weight Rating (GAWR) of either the front or
rear axles has been exceeded but the total load is
within the specified GVWR. If so, weight must be
shifted from front to rear or rear to front as
appropriate until the specified weight limitations
are met. Store the heavier items down low and be
sure that the weight is distributed equally. Stow all
loose items securely before driving.
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
CAUTION!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Also, overloading can
shorten the life of your vehicle.

STARTING AND OPERATING213
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú page 211.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight
of all cargo, consumables and equipment
(permanent or temporary) loaded in or on the
trailer in its “loaded and ready for operation”
condition.
The recommended way to measure GTW is to put
your fully loaded trailer on a vehicle scale. The
entire weight of the trailer must be supported by
the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your
vehicle and trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do not
exceed either front or rear GAWR Úpage 211.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
The electronic TSC (If equipped) recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle.
These kinds of hitches are commonly used to tow
small and medium sized trailers.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg)
or more, it is recommended to use a
weight-distributing hitch to ensure stable
handling of your vehicle. If you use a standard
weight-carrying hitch, you could lose control of
your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the vehicle
and have a collision.

“Trailer Steering Unavailable” will display if
there is a fault in the system preventing activa -
tion, the driver’s door is open, the driver’s seat
belt is unbuckled, or the tailgate is open. Other reasons the feature may cancel:
The driver overrides steering by placing hands
on the steering wheel.
Trailer tracking is lost.
If the trailer angle becomes excessive, the
brakes apply bringing the vehicle to a stop and
then applying the parking brake.
Trailer steering button is pushed while active.
Vehicle speed goes over 8 mph (12 km/h).
Driver door is open and seat belt is unbuckled.
Transmission shifted to PARK.
Trailer Memory
The trailer steering system will automatically retain
the calibration of the previous five trailers
connected, so recalibration will not be necessary
when hooking up. The next time the vehicle is
started, place the vehicle in DRIVE and drive a
short distance. The TRSC system can then be
activated.
NOTE:Trailers may look different during day and night
conditions. In such cases, the trailer may need to
recalibrate. Some trailers (such as boat trailers) will need to
recalibrate while loaded and unloaded.
NOTE:
The system may not detect a trailer in low light
conditions. In sunny conditions, the perfor
-
mance may be degraded as shadows pass over
the trailer.
The driver is always responsible for safe opera -
tion of truck and trailer.
The driver is always in control of the truck as
well as the trailer and is responsible for
controlling the throttle and brakes.
The system may not function when the camera
lens is blocked, blurred (covered with water,
snow, ice, dirt, etc) and will not work unless the
tailgate is upright and fully latched.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle
drivetrain components, the following guidelines
are recommended.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.

220STARTING AND OPERATING
(Continued)
Perform the maintenance listed in the Scheduled
Servicing section for the proper maintenance
intervals
Úpage 393. When towing a trailer, never
exceed the GAWR or GCWR ratings.
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.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 444.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer.
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.
Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
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
difficult 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. Overloading
can cause a loss of control, poor performance
or damage to brakes, axle, engine, transmis -
sion, steering, suspension, chassis structure
or tires.
CAUTION!
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.
WARNING!

STARTING AND OPERATING221
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).Integrated Trailer Brake Module (ITBM) —
If Equipped
Your vehicle may have an ITBM for electric and
Electric Over Hydraulic (EOH) trailer brakes.
NOTE:This module has been designed and verified with
electric trailer brakes and new EOH systems.
Some previous EOH systems may not be
compatible with ITBM.

Integrated Trailer Brake Module (ITBM)
The user interface consists of the following:
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control
power output to the trailer brakes in
0.5 increments. The GAIN setting can be increased
to a maximum of 10 or decreased to a minimum of
0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake
control for the specific towing condition and should
be changed as towing conditions change. Changes
to towing conditions include trailer load, vehicle
load, road conditions and weather.
Manual Brake Control Lever
Slide the manual brake control lever to the left to
activate power to the trailer's electric brakes
independent of the tow vehicle's brakes. If the
manual brake control lever is activated while the
brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
The trailer and the vehicle’s stop lamps will come
on when braking normally with the vehicle brake
pedal. Only the trailer stop lamps will come on
when the manual brake control lever is applied.
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do
this could lead to accelerated brake lining wear,
higher brake pedal effort, and longer stopping
distances.

Adjusting GAIN
NOTE:This should only be performed in a traffic free envi -
ronment at speeds of approximately 20–25 mph
(30–40 km/h).
1. Make sure the trailer brakes are in good
working condition, functioning normally and
properly adjusted. See your trailer dealer if
necessary.

2. Hook up the trailer and make the electrical connections according to the trailer
manufacturer's instructions.
3. When a trailer is plugged in with electric or EOH brakes, the trailer connected message
should appear in the instrument cluster
display (if the connection is not recognized by
the ITBM, braking functions will not be
available), the GAIN setting will illuminate and
the correct type of trailer must be selected
from the instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the
screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”. 6. Push the UP or DOWN buttons until the Trailer
Brake Type appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake
Type appears on the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20–25 mph
(30–40 km/h) and squeeze the manual brake
control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting;
if the trailer wheels turn freely, increase the
GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a
point just below trailer wheel lockup. If towing a
heavier trailer, trailer wheel lockup may not be
attainable even with the maximum GAIN setting
of 10.
