weight RAM CHASSIS CAB 2022 User Guide

184STARTING AND OPERATING
The loaded vehicle weight, including the snowplow
system, all aftermarket accessories, driver,
passengers, options, and cargo, must not exceed
either the Gross Vehicle Weight Rating (GVWR) or
Gross Axle Weight Rating (GAWR). These weights
are specified on the Safety Compliance
Certification Label on the driver's side door
opening.
NOTE:Detach the snowplow when transporting
passengers.
Vehicle front end wheel alignment was set to
specifications at the factory without consideration
for the weight of the plow. Front end toe-in should
be checked and reset if necessary at the beginning
and end of the snowplow season. This will help
prevent uneven tire wear.
The blade should be lowered whenever the vehicle
is parked.
Maintain and operate your vehicle and snowplow
equipment following the recommendations
provided by the specific snowplow manufacturer.
OVER THE ROAD OPERATION WITH
S
NOWPLOW ATTACHED
The blade restricts air flow to the radiator and
causes the engine to operate at higher than
normal temperatures. Therefore, when
transporting the plow, angle the blade completely
and position it as low as road or surface conditions
permit. Do not exceed 40 mph (64 km/h). The
operator should always maintain a safe stopping
distance and allow adequate passing clearance.
OPERATING TIPS
Under ideal snow plowing conditions, 20 mph
(32 km/h) should be maximum operating speed.
The operator should be familiar with the area and
surface to be cleaned. Reduce speed and use
extreme caution when plowing unfamiliar areas or
under poor visibility.
GENERAL MAINTENANCE
Snowplows should be maintained in accordance
with the plow manufacturer's instructions.
Keep all snowplow electrical connections and
battery terminals clean and free of corrosion.
When plowing snow, to avoid transmission and
drivetrain damage, the following precautions
should be observed.
Operate with transfer case in 4WD LOW when
plowing small or congested areas where speeds
are not likely to exceed 15 mph (24 km/h). At
higher speeds operate in 4WD HIGH.
Vehicles with automatic transmissions should
use 4WD LOW when plowing deep or heavy
snow for extended periods of time to avoid
transmission overheating.
Do not shift the transmission unless the engine
has returned to idle and wheels have stopped.
Make a practice of stepping on the brake pedal
while shifting the transmission.

266SAFETY
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
NOTE:TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations
Úpage 173.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the
brakes being applied to individual wheels to
attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial
Off” or “Full Off” modes.
AUXILIARY DRIVING SYSTEMS
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a brake
jerk to warn the driver when it detects a potential
frontal collision. The warnings and limited braking
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 the 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 warnings as
well as a possible brake jerk warning.
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 warnings 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. If an FCW with Mitigation event begins at a speed
below 32 mph (52 km/h), the system may provide
the maximum braking possible to mitigate 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

When the system determines a collision with the
vehicle in front of you is no longer probable, the
warning message will be deactivated Úpage 412.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.

22_DPF_OM_EN_USC_t.book Page 266

268SAFETY
This setting provides less reaction time than
the “Far” and “Medium” settings, which
allows for a more dynamic driving experi -
ence.
More dynamic or aggressive drivers that
want to avoid frequent warnings may prefer
this setting.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield”
momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still
drivable under normal conditions, the active
braking may not be fully available. Once the
condition that limited the system performance is
no longer present, the system will return to its full
performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster
displays:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
(Vehicles Under 10K Gross Vehicle Weight Rating
(GVWR) Only)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
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 pressure values of
each tire with the low tire pressure 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.
The tire pressure will also increase as the vehicle
is driven — this is normal and there should be no
adjustment for this increased pressure.
See Ú
page 376 on how to properly inflate the
vehicle’s tires.
The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low-pressure
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 pressure. Once the
low TPMS Warning Light illuminates, 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.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the TPMS Warning Light off.

Infant And Child Restraints
Safety experts recommend that children ride
rear-facing in the vehicle until they are two years
old or until they reach either the height or weight
limit of their rear-facing child restraint. Two types of
child restraints can be used rear-facing: infant
carriers and convertible child seats.
The infant carrier is only used rear-facing in the
vehicle. It is recommended for children from birth
until they reach the weight or height limit of the
infant carrier. Convertible child seats can be used
either rear-facing or forward-facing in the vehicle.
Convertible child seats often have a higher weight
limit in the rear-facing direction than infant carriers
do, so they can be used rear-facing by children who
have outgrown their infant carrier but are still less
than at least two years old. Children should remain
rear-facing until they reach the highest weight or
height allowed by their convertible child seat.
Older Children And Child Restraints
Children who are two years old or who have
outgrown their rear-facing convertible child seat
can ride forward-facing in the vehicle.
Forward-facing child seats and convertible child
seats used in the forward-facing direction are for
children who are over two years old or who have
outgrown the rear-facing weight or height limit of
their rear-facing convertible child seat. Children
should remain in a forward-facing child seat with a
harness for as long as possible, up to the highest
weight or height allowed by the child seat.
All children whose weight or height is above the
forward-facing limit for the child seat should use a
belt-positioning booster seat until the vehicle’s
seat belts fit properly. If the child cannot sit with
knees bent over the vehicle’s seat cushion while
the child’s back is against the seatback, they
should use a belt-positioning booster seat. The
child and belt-positioning booster seat are held in
the vehicle by the seat belt.
WARNING!
Never place a rear-facing child restraint in
front of an air bag. A deploying passenger
front air bag can cause death or serious injury
to a child 12 years or younger, including a
child in a rear-facing child restraint.
Never install a rear-facing child restraint in the
front seat of a vehicle. Only use a rear-facing
child restraint in the rear seat. If the vehicle
does not have a rear seat, do not transport a
rear-facing child restraint in that vehicle.
WARNING!
Do not install a rear-facing car seat using a rear
support leg in this vehicle. The floor of this
vehicle is not designed to manage the crash
forces of this type of car seat. In a crash, the
support leg may not function as it was designed
by the car seat manufacturer, and your child may
be more severely injured as a result.
WARNING!
WARNING!
Improper installation can lead to failure of an
infant or child restraint. It could come loose in
a collision. The child could be badly injured or
killed. Follow the child restraint manufac
-
turer’s directions exactly when installing an
infant or child restraint.

Recommendations For Attaching Child Restraints
Lower Anchors And Tethers For CHildren
(LATCH) Restraint System

LATCH Label
Your vehicle is equipped with the child restraint
anchorage system called LATCH, which stands for
Lower Anchors and Tethers for CHildren. The
LATCH system has three vehicle anchor points for
installing LATCH-equipped child seats. There are
two lower anchorages located at the back of the
seat cushion where it meets the seatback and one
top tether anchorage located behind the seating
position. These anchorages are used to install
LATCH-equipped child seats without using the
vehicle’s seat belts. Some seating positions may
have a top tether anchorage but no lower
anchorages. In these seating positions, the seat
belt must be used with the top tether anchorage to
install the child restraint. Please see the following
table for more information.

Frequently Asked Questions About Installing Child Restraints With LATCH
What is the weight limit (child’s weight + weight of the child
restraint) for using the LATCH anchorage system to attach the
child restraint? 65 lbs (29.5 kg)Use the LATCH anchorage system until the combined weight
of the child and the child restraint is 65 lbs (29.5 kg). Use the
seat belt and tether anchor instead of the LATCH system once
the combined weight is more than 65 lbs (29.5 kg).
Can the LATCH anchorages and the seat belt be used together
to attach a rear-facing or forward-facing child restraint? NoDo not use the seat belt when you use the LATCH anchorage
system to attach a rear-facing or forward-facing child
restraint.
Booster seats may be attached to the LATCH anchorages if
allowed by the booster seat manufacturer. See your booster
seat owner’s manual for more information.
Can a child seat be installed in the center position using the
inner LATCH lower anchorages from the outboard seating
positions? N/A – Regular / Crew Split
