ECU RAM 1500 2022 Service Manual

STARTING AND OPERATING183
NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action and
does not mean that the Forward Collision Warning
system is applying the brakes autonomously.

Overtake Aid
When driving with Adaptive Cruise Control (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
In the event that the ACC system brings your
vehicle to a standstill while following the vehicle in
front, if the vehicle in front starts moving within two
seconds of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the vehicle in front does not start moving within
two seconds of your vehicle coming to a standstill,
the driver will either have to push the RES (resume)
button, or apply the accelerator pedal to reengage
the ACC to the existing set speed.
NOTE:After the ACC system holds your vehicle at a stand -
still for approximately three consecutive minutes, the parking brake will be activated, and the ACC
system will be canceled.
While ACC is holding your vehicle at a standstill, if
the driver seat belt is unbuckled or the driver door
is opened, the parking brake will be activated, and
the ACC system will be canceled.
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning will display and a chime will
sound when conditions temporarily limit system
performance.
This most often occurs at times of poor visibility,
such as in snow or heavy rain. The ACC system may
also become temporarily blinded due to
obstructions, such as mud, dirt or ice. In these
cases, the instrument cluster display will display
“ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.The “ACC/FCW Unavailable Wipe Front Radar
Sensor” message can sometimes be displayed
while driving in highly reflective areas (i.e. ice and
snow, or tunnels with reflective tiles). The ACC
system will recover after the vehicle has left these
areas. Under rare conditions, when the radar is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar
Sensor” warning is active, Fixed Speed Cruise
Control is still available.
If weather conditions are not a factor, the driver
should examine the sensor. It may require cleaning
or removal of an obstruction. The sensor is located
in the camera in the center of the windshield, on
the forward side of the rearview mirror.
To keep the ACC system operating properly, it is
important to note the following maintenance
items:
Always keep the sensor clean. Carefully clear
the windshield.
Do not remove any screws from the sensor.
Doing so could cause an ACC system malfunc
-
tion or failure and require a sensor realignment.
Do not attach or install any accessories near the
sensor, including transparent material. Doing so
could cause an ACC system failure or malfunc -
tion.
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in a
collision and death or serious personal injury.

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.

22_DT_OM_EN_USC_t.book Page 212

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!

Recreational towing (for two-wheel drive models) is
allowed ONLY if the rear wheels are OFF the
ground. This may be accomplished using a tow
dolly or vehicle trailer. If using a tow dolly, follow
this procedure:
NOTE:If vehicle is equipped with air suspension, ensure
the vehicle is set to Normal Ride Height.

1. Properly secure the dolly to the tow vehicle, following the dolly manufacturer's
instructions.

2. Drive the rear wheels onto the tow dolly.
3. Apply the parking brake. Place the transmission in PARK.
4. Properly secure the rear wheels to the dolly, following the dolly manufacturer's instructions.
5. Turn the ignition OFF.
6. Install a suitable clamping device, designed for towing, to secure the front wheels in the
straight position.
RECREATIONAL TOWING —
F
OUR-WHEEL DRIVE MODELS
NOTE:The transfer case must be shifted into N (Neutral)
for recreational towing. The transmission must be
shifted into PARK for recreational towing. Refer to
the following for the proper transfer case N
(Neutral) shifting procedure for your vehicle.
CAUTION!
Towing with the rear wheels on the ground will
cause severe transmission damage. Damage
from improper towing is not covered under the
New Vehicle Limited Warranty.
CAUTION!
DO NOT dolly tow any 4WD vehicle. Towing
with only one set of wheels on the ground
(front or rear) will cause severe transmission
and/or transfer case damage. Tow with all
four wheels either ON the ground, or OFF the
ground (using a vehicle trailer).
Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage
to the transfer case.
Before recreational towing, the transfer case
must be in N (Neutral). To be certain the
transfer case is fully in N (Neutral), perform
the procedure outlined under “Shifting Into
N (Neutral)”. Internal transmission damage
will result, if the transfer case is not in N
(Neutral) during towing.
The transmission must be in PARK for recre -
ational towing.
Ensure that the Electric Park Brake is
released, and remains released, while being
towed.
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
Do not disconnect the rear driveshaft because
fluid will leak from the transfer case, causing
damage to internal parts.
Do not use a fascia/bumper-mounted
clamp-on tow bar on your vehicle. The fascia/
bumper face bar will be damaged.
