2019 Ram 1500 steering

The locking rear axle is controlled by the AXLE LOCKER
button.
Under normal driving conditions, the rear axle should be
unlocked.
During the command to lock the rear axle, the indicator
light will flash until the axle is locked. After the lock
command has been successfully executed, the light will
remain on solid.
Operating in 4WD LOW the locker can be engaged up to
40 mph (64 km/h) and will remain engaged throughout the
4WD LOW speed range.
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 reengage at 20 mph
(32 km/h).
NOTE:Left to right wheel speed difference may be neces-
sary 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 simi-
larly 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
6
STARTING AND OPERATING 335

rear wheel on an excessively slippery surface, slight mo-
mentary application of the parking brake may be necessary
to gain maximum traction.
WARNING!
When servicing vehicles equipped with a limited-slip
or locking differential never run the engine with one
rear wheel off the ground since the vehicle may drive
through the rear wheel remaining on the ground and
result in unintended movement.
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 give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will vary its assist to provide light
efforts while parking and good feel while driving. If the electric steering system experiences a fault that prevents it
from providing assist, you will still have the ability to steer
the vehicle manually.
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 STEER-
ING SYSTEM OVER TEMP” message is displayed on the
instrument cluster screen, they indicate that extreme steer-
ing maneuvers may have occurred which caused 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.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
If the Steering icon is displayed and the “SERVICE POWER
STEERING – ASSIST OFF” message is displayed the in-
strument cluster screen, they indicate the vehicle needs to
be taken to the dealer for service. Refer to “Instrument
Cluster Display” in “Getting To Know Your Instrument
Panel” for further information.
336 STARTING 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, especially at low speeds and during
parking maneuvers.
• If the condition persists, see your 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 is developed to save fuel and
reduce emissions. The system will stop the engine auto-
matically during a vehicle stop if the required conditions
are met. Releasing the brake pedal 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 for use on engine
startup after a stop as well as providing launch torque
assist.
Automatic Mode
The Stop/Start feature is enabled after every normal cus-
tomer 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, can go into an STOP/START AUTO STOP 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. Refer
to “Instrument Cluster Display” in “Getting To know
Your Instrument Panel” for further information.
2. The vehicle must be completely stopped.
3. The transmission Gear Selector must be in DRIVE and the brake pedal depressed.
6
STARTING AND OPERATING 337

3. At the next vehicle stop (after turning off the STOP/START system) the engine will not be stopped.
4. If the STOP/START system is manually turned off, the engine can be started and stopped by cycling the
ignition switch or pressing the STOP/START switch
again.
5. The STOP/START system will reset itself back to an ON condition every time the key is turned off and back on.
To Manually Turn On The Stop Start System
1. Push the STOP/START Off switch (located near the gearselector module).
2. The light on the switch will turn off.
System Malfunction
If there is a malfunction in the STOP/START system, the
system will not shut down the engine. A “SERVICE STOP/
START SYSTEM” message will appear in the instrument
cluster display. Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” for further
information.
The system will need to be checked by your authorized
dealer.

ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following a target vehicle, if the target
vehicle 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 target vehicle 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
standstill for approximately 3 consecutive minutes, the
parking brake will be activated, and the ACC system will
be cancelled.
While ACC is holding your vehicle at a standstill, if the
driver seatbelt is unbuckled or the driver door is opened,
the parking brake will be activated, and the ACC system
will be cancelled.
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.
Adaptive Cruise Control (ACC) Menu
The instrument cluster display will show the current ACC
system settings. The instrument cluster display is located
in the center of the instrument cluster. The information it
displays depends on ACC system status.
Push the Adaptive Cruise Control (ACC) on/off button
(located on the steering wheel) until one of the following
appears in the instrument cluster display:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adaptive
Cruise Control Off.”

• System Off
• ACC Proximity Warning
• ACC Unavailable Warning
• The instrument cluster display will return to the last
display selected after five seconds of no ACC display
activityDisplay Warnings And Maintenance
“Wipe Front Radar Sensor In Front Of Vehicle”
Warning
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and also a chime will indicate 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 Sen-
sor” 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. tunnels with reflective tiles, or
ice and snow). 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 Normal (Fixed Speed) Cruise
Control is still available. For additional information refer to
“Normal (Fixed Speed) Cruise Control Mode” in this section.

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.
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, provid-
ing audible/visual instructions, and controlling the steer-
ing wheel. The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver maintains
control of the accelerator, gear selector and brakes. De-
pending on the driver’s parking maneuver selection, the ParkSense Active Park Assist system is capable of maneu-
vering 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. envi-
ronmental 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 calibrated and performs
accurately. This is due to the system’s dynamic vehicle
calibration to improve the performance of the feature.
