2019 Ram 1500 wheel torque

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

WARNING!(Continued)
the ParkSense Active Park Assist system. Always
check carefully behind and in front of your vehicle,
look behind and in front of you, and be sure to check
for pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up and moving for-
ward. You are responsible for safety and must continue
to pay attention to your surroundings. Failure to do so
can result in serious injury or death.
CAUTION!
•The ParkSense Active Park Assist system 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 the
ParkSense Active Park Assist system 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 the ParkSense Active Park
Assist system.
LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at speeds above
37 mph (60 km/h) and below 112 mph (180 km/h). It uses
a forward looking camera to detect lane markings and
measure vehicle position within the lane boundaries.
When both lane markings are detected and the driver
unintentionally drifts out of the lane while no turn signal
has been applied OR the driver departs the lane on the
opposite side of the applied turn signal (if the left turn
signal is applied and the vehicle departs to the right), the
LaneSense system provides a haptic warning in the form of
torque applied to the steering wheel to prompt the driver
to remain within the lane boundaries. The LaneSense
system will also provide a visual warning through the
instrument cluster display to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic warning by
applying torque into the steering wheel at any time.
When only a single lane marking is detected and the driver
unintentionally drifts across that lane marking (no turn
signal applied), the LaneSense system provides a visual
warning through the instrument cluster display to prompt
6
STARTING AND OPERATING 391

the driver to remain within the lane. When only a single
lane marking is detected, a haptic (torque) warning will not
be provided.
NOTE:When operating conditions have been met, the
LaneSense system will monitor if the driver ’s hands are on
the steering wheel and provides an audible and visual
warning to the driver when the driver ’s hands are not
detected on the steering wheel. The system will cancel if
the driver does not return their hands to the wheel.
Turning LaneSense On Or Off
The LaneSense button is located on the switch
panel below the Uconnect display.
NOTE: If your vehicle is equipped with a 12–inch
Uconnect Display screen, the LaneSense button is located
above the display.
To turn the LaneSense system on, push the LaneSense
button (LED turns off). A “LaneSense On” message is
shown in the instrument cluster display. To turn the LaneSense system off, push the LaneSense
button again (LED turns on).
NOTE:
The LaneSense system will retain the last system
state on or off from the last ignition cycle when the ignition
is changed to the ON/RUN position.Lane Sense On Message
392 STARTING AND OPERATING

NOTE:The LaneSense system operates with the similar
behavior for a right lane departure when only the right
lane marking has been detected.
Left Lane Departure — Both Lane Lines Detected
• When the LaneSense system is ON and both the lane
markings have been detected, the system is armedto
provide visual warnings in the instrument cluster dis-
play and a torque warning in the steering wheel if an
unintentional lane departure occurs .The lane lines turn
from gray to white and the LaneSense telltale
is solid
green.
• 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.

Telltale
394 STARTING AND OPERATING

•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.
NOTE: The LaneSense system operates with the 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 screen. Refer to “Uconnect Settings” in
“Multimedia” for further information.
NOTE:
• When enabled the system operates above 37 mph
(60 km/h) and below 112 mph (180 km/h).
• Use of the turn signal suppresses the warnings.
• The system will not apply torque to the steering wheel
whenever a safety system engages (anti-lock brakes,
traction control system, electronic stability control, for-
ward collision warning, etc.).

CAUTION!(Continued)
•Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always in-
spect your vehicle’s fluids (i.e., engine oil, transmis-
sion, axle, etc.) for signs of contamination (i.e., fluid
that is milky or foamy in appearance) after driving
through standing water. Do not continue to operate
the vehicle if any fluid appears contaminated, as this
may result in further damage. Such damage is not
covered by the New Vehicle Limited Warranty.
• Getting water inside your vehicle’s engine can cause
it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered by
the New Vehicle Limited Warranty.
Off-Road Driving Tips
Care should be taken when attempting to climb steep hills
or driving diagonally across a hill or slope. If natural
obstacles force you to travel diagonally up or down a hill,
choose a mild angle and keep as little side tilt as possible.
Keep the vehicle moving and make turns slowly and
cautiously. If you must back down a hill, back straight down using
REVERSE gear. Never back down in NEUTRAL or diago-
nally across the hill.
When driving over sand, mud, and other soft terrain, shift
to low gear and drive steadily. Apply the accelerator slowly
to avoid spinning the wheels.
Do not reduce the tire pressures for this type of driving.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•
Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.6

WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.
5. Remove the lug nuts and pull the wheel off. Install the spare wheel and lug nuts with the cone shaped end of
the lug nuts toward the wheel. Hand tighten the lug
nuts with vehicle lifted. To avoid the risk of forcing the
vehicle off the jack, do not fully tighten the lug nuts until
the vehicle has been lowered.
6. Lower vehicle to ground, finish tightening the lug nuts. Push down on the wrench while at the end of the handle
for increased leverage. Tighten the lug nuts in a star
pattern until each nut has been tightened twice.
NOTE: For the correct lug nut torque refer to “Torque
Specifications” in “Technical Specifications.”If in doubt
about the correct tightness, have them checked with a
torque wrench by an authorized dealer or service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.
7. Install the wheel center cap and remove the wheel blocks. Do not install chrome or aluminum wheel center
caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. Stow the replaced tire, jack, and tools as previously described.
9. Adjust the tire pressure when possible.
To Stow The Flat Or Spare
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided. Have the deflated (flat) tire repaired
or replaced immediately.
