wheel torque JEEP CHEROKEE 2023 User Guide

144SAFETY
Your vehicle may also be equipped with Dynamic Steering
Torque (DST), Hill Descent Control (HDC), Rain Brake
Support (RBS), Ready Alert Braking (RAB), Selec-Speed
Control (SSC), and Trailer Sway Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sensing
the rate and amount of brake application and then applies
optimum pressure to the brakes. This can help reduce
braking distances. The BAS complements the Anti-Lock
Brake System (ABS). Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit
of the system, you must apply continuous braking
pressure during the stopping sequence (do not “pump”
the brakes). Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake pedal is
released, the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on when the
ignition is placed in the ON/RUN mode and may stay on for
as long as four seconds.
If the Brake System Warning Light remains on or comes on
while driving, it indicates that the brake system is not
functioning properly and that immediate service is
required. If the Brake System Warning Light does not
come on when the ignition is placed in the ON/RUN mode,
have the light repaired as soon as possible.
Dynamic Steering Torque (DST)
DST is a feature of the Electronic Stability Control (ESC)
and the Electric Power Steering (EPS) modules, that
provides torque at the steering wheel for certain driving
conditions, in which the ESC module is detecting vehicle
instability. The torque that the steering wheel receives is
only meant to help the driver realize optimal steering
behavior in order to reach/maintain vehicle stability. The
only notification the driver receives that the feature is
active is the torque applied to the steering wheel.
NOTE:The DST feature is only meant to help the driver realize the
correct course of action through small torques on the
steering wheel, which means the effectiveness of the DST
feature is highly dependent on the driver’s sensitivity and
overall reaction to the applied torque. It is very important
to realize that this feature will not steer the vehicle,
meaning the driver is still responsible for steering the
vehicle.
Electronic Brake Force Distribution (EBD)

EBD function manages the distribution of the braking
torque between the front and rear axles by limiting braking
pressure to the rear axle. This is done to prevent overslip of
the rear wheels to avoid vehicle instability, and to prevent
the rear axle from entering ABS before the front axle.

Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by monitoring
the driver’s steering wheel input and the speed of the
vehicle. When ERM determines that the rate of change of
the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during severe or
evasive driving maneuvers; it cannot prevent wheel lift
due to other factors, such as road conditions, leaving the
roadway, or striking objects or other vehicles.
NOTE:ERM is disabled any time the ESC is in “Full Off” mode (if
equipped) Úpage 145.
WARNING!
The Brake Assist System (BAS) cannot prevent the natu -
ral laws of physics from acting on the vehicle, nor can it
increase the traction afforded by prevailing road condi -
tions. BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user's safety or the safety of others.
WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The capa -
bilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
The driver pushes the SSC button.
 The driveline is shifted out of 4WD Low.
 The parking brake is applied.
 The driver door opens.
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h)
(SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
button has an LED which offers feedback to the driver
about the state SSC is in.
 The cluster icon and button lamp will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC.
 The cluster icon and button lamp will flash for several
seconds then extinguish when the driver pushes the
SSC button but enable conditions are not met.
 The cluster icon and button lamp will flash for several
seconds then extinguish when SSC disables due to
excess speed.
 The cluster icon and button lamp will flash then extin -
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine torque to be applied to the wheel that
is not spinning. BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in reduced modes.
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 114.
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
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
BSM uses two radar sensors, located inside the rear
fascia/bumper, to detect highway licensable vehicles
(automobiles, trucks, motorcycles, etc.) that enter the
blind spot zones from the rear/front/side of the vehicle.

Rear Detection Zones

WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.
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.

IN CASE OF EMERGENCY195
6. Remove the wheel bolts and tire.
7. Remove the alignment pin from the jack assembly
and thread the pin into the wheel hub to assist in
mounting the spare tire.

Installing Alignment Pin

8. Mount the spare tire.

Mounting Spare Tire

NOTE:
For vehicles equipped, do not attempt to install a center
cap or wheel cover on the compact spare Úpage 245.
9. Install the wheel bolts with the threaded end of the wheel bolt toward the wheel. Lightly tighten the wheel
bolts.

Installing Wheel Bolts

10. Lower the vehicle to the ground by turning the jack handle counterclockwise.
11. Finish tightening the wheel bolts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern
until each wheel bolt has been tightened twice. If in
doubt about the correct tightness, have them
checked with a torque wrench by an authorized
dealer or at a service station
Úpage 253.
12. After 25 miles (40 km), check the wheel bolt torque with a torque wrench to ensure that all wheel bolts
are properly seated against the wheel.
CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered to the ground. Failure to follow this
warning may result in serious injury.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the instrument
panel. The VIN is visible from outside of the vehicle
through the windshield.

Vehicle Identification Number

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose normal
capability, the remaining system will still function.
However, there will be some loss of overall braking
effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow or
stop, and potential activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine OFF) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle,
the lug nuts/bolts should be torqued using a properly
calibrated torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/bolts
and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
