2022 RAM 1500 instrument cluster

STARTING AND OPERATING173
Operating the locker in 2WD, 4WD AUTO, and
4WD LOCK/HIGH, the locker can be engaged up to
20 mph (32 km/h). While driving with the locker
engaged, if speed exceeds 25 mph (40 km/h), the
locker will automatically disengage, but will
automatically re-engage at 20 mph (32 km/h).
NOTE:Left to right wheel speed difference may be
necessary to allow the rear axle to fully lock. If the
indicator light is flashing after selecting the rear
axle lock mode, drive the vehicle in a turn or on
loose gravel to expedite the locking action.
The axle locker could become torque locked due to
side to side loads on the rear axle. Driving slowly
while turning the steering wheel from a left hand
turn to a right hand turn or driving in REVERSE for
a short distance may be required to release the
torque lock and unlock the axles.
To unlock the rear axle, push the AXLE LOCK
button. The AXLE LOCK indicator light will go out
when the rear axle is unlocked.
LIMITED-SLIP DIFFERENTIAL —
IF EQUIPPED
The limited-slip differential provides additional
traction on snow, ice, mud, sand and gravel,
particularly when there is a difference between the
traction characteristics of the surface under the
right and left rear wheels. During normal driving and cornering, the limited-slip unit performs
similarly to a conventional differential. On slippery
surfaces, however, the differential delivers more of
the driving effort to the rear wheel having the
better traction.
The limited-slip differential is especially helpful
during slippery driving conditions. With both rear
wheels on a slippery surface, a slight application of
the accelerator will supply maximum traction.
When starting with only one rear wheel on an
excessively slippery surface, slight momentary
application of the parking brake may be necessary
to gain maximum traction.
Care should be taken to avoid sudden
accelerations when both rear wheels are on a
slippery surface. This could cause both rear wheels
to spin, and allow the vehicle to slide sideways on
the crowned surface of a road or in a turn.
POWER STEERING
ELECTRIC POWER STEERING
The electric power steering system will provide
increased vehicle response and ease of
maneuverability. The power steering system
adapts to different driving conditions.
If the steering icon is flashing, it indicates that the
vehicle needs to be taken to the dealer for service.
It is likely the vehicle has lost power steering
assistance.
If the steering icon is displayed and the “POWER
STEERING SYSTEM OVER TEMP” message is
displayed on the instrument cluster screen, this
indicates an over temperature condition in the
power steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the icon and message turn off
Ú
page 114.
If the steering icon is displayed and the “SERVICE
POWER STEERING – ASSIST OFF” message is
displayed on the instrument cluster screen, this
indicates the vehicle needs to be taken to the
dealer for service Ú page 114.
WARNING!
When servicing vehicles equipped with a
limited-slip or locking differential, never run the
engine with one rear wheel off the ground as the
vehicle may drive through the rear wheel
remaining on the ground and result in
unintended movement.

174STARTING AND OPERATING
NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer the
vehicle. Under these conditions there will be a
substantial increase in steering effort, espe -
cially at low speeds and during parking maneu -
vers.
If the condition persists, see an authorized
dealer for service.
FUEL SAVER TECHNOLOGY 5.7L ENGINES
ONLY — IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The system
is automatic with no driver inputs or additional
driving skills required.
NOTE:This system may take some time to return to full
functionality after a battery disconnect.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function, included with eTorque
equipped vehicles, is developed to save fuel and
reduce emissions. The system will stop the engine
automatically as the vehicle decelerates at low
speeds if the required conditions are met. Releasing the brake pedal or shifting out of DRIVE
will automatically restart the engine.
Vehicles equipped with eTorque contain a
heavy-duty motor generator and an additional
hybrid electric battery to store energy from vehicle
deceleration used to expand engine off energy
storage and for engine startup after a stop, as well
as providing engine torque assist when conditions
are met to enable this.
AUTOSTOP MODE
The Stop/Start feature is enabled after every
normal customer engine start. It will remain in
STOP/START NOT READY until you drive forward
with a vehicle speed greater than 2 mph (3 km/h).
At that time, the system will go into STOP/START
READY and if all other conditions are met, the
system may go into STOP/START AUTOSTOP
ACTIVE Autostop mode.
To Activate The Autostop Mode, The Following
Must Occur:

1. The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster within the
Stop/Start section
Ú
page 114.

2. The vehicle must be decelerating and likely coming to a complete stop.
3. The transmission gear selector must be in DRIVE and the brake pedal pressed. The engine will shut down, the tachometer will
move to the zero position and the stop/start
telltale will illuminate indicating you are in an
Autostop. While in an Autostop, the Climate
Controls system may automatically adjust airflow
to maintain cabin comfort. Customer settings will
be maintained upon return to an engine running
condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check
many safety and comfort conditions to see if they
are fulfilled. In following situations, the engine will
not Autostop:
Driver’s seat belt is not buckled
Driver’s door is not closed
The vehicle is on a steep grade
Cabin heating or cooling is in process and an
acceptable cabin temperature has not been
achieved
HVAC is set to full defrost mode at a high blower
speed
Engine has not reached normal operating
temperature
Engine or exhaust temperature is too high
The battery is charging

22_DT_OM_EN_USC_t.book Page 174

STARTING AND OPERATING175
The transmission is not in DRIVE
Hood is open
Transfer case is in 4WD LOW
TOW/HAUL mode is selected
Accelerator pedal input
Excessive 12 Volt loads
Brake application is adequate to obtain and
maintain a stop
It may be possible to operate the vehicle several
consecutive times in extreme conditions and not
meet all criteria to enable an Autostop state.
TO START THE ENGINE WHILE IN
A
UTOSTOP MODE
While in DRIVE, the engine will start when the
brake pedal is released or the throttle pedal is
pressed and the transmission will automatically
reengage upon engine restart.
Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode
The engine will start automatically when:
The transmission selector is moved from DRIVE
to REVERSE, NEUTRAL, or PARK
To maintain cabin temperature near the HVAC
settings
HVAC is set to full defrost mode
12 Volt demand requires engine restart
Stop/Start OFF switch is pushed
Transfer case is in 4WD LOW
The emissions system override is present
A Stop/Start system error is present
Conditions That Force An Automatic Shift To Park
While In Autostop Mode
The engine will not start automatically and the
transmission will be placed in PARK if:
The driver door is open and brake pedal
released
The driver door is open and the driver seat belt
is unbuckled
The engine hood has been opened
A Stop/Start system error is present
The engine may then be restarted by moving the
transmission shift selector out of PARK (e.g., to
DRIVE) or, in some cases, only by a key start. The
instrument cluster will display a “SHIFT OUT OF
PARK” message, or a “STOP/START KEY START
REQUIRED” message, to indicate which action is
required Ú page 114.
TO MANUALLY TURN OFF THE STOP/
S
TART SYSTEM

Stop/Start OFF Switch

Push the Stop/Start OFF switch (located on the
switch bank). The light on the switch will illuminate.
The “STOP/START OFF” message will appear in the
instrument cluster display and the Autostop mode
will be disabled Ú page 114.

the system will not shut down the engine. A
“SERVICE STOP/START SYSTEM” message will
appear in the instrument cluster display
Úpage 128.
The system will need to be checked by an
authorized dealer.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise
Control system, or the Adaptive Cruise Control
(ACC) system:
Cruise Control will keep your vehicle at a
constant preset speed.
Adaptive Cruise Control (ACC) will adjust the
vehicle speed up to the preset speed to main -
tain a distance with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not
enabled, Fixed Speed Cruise Control will not
detect vehicles directly ahead of you. Always be
aware of the feature selected.
Only one Cruise Control feature can operate at a
time. For example, if Fixed Speed Cruise Control
is enabled, Adaptive Cruise Control will be
unavailable, and vice versa.
CRUISE CONTROL
