2018 JEEP CHEROKEE suspension

ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
• Oversteer — when the vehicle is turningmore than appropriate for the steering
wheel position.
• Understeer — when the vehicle is turning less than appropriate for the steering wheel
position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and
driving to the prevailing road conditions.WARNING!
• Electronic Stability Control (ESC) can- not prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents re-
sulting from loss of vehicle control due
to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skill-
ful driver can prevent accidents. The
capabilities of an ESC equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopar-
dize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
WARNING!
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.
ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple op-
erating modes.
ESC On
This is the normal operating mode for the
ESC. Whenever the vehicle is started, the
ESC system will be in this mode. This mode

Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
devices to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
NOTE:
• You must ensure that the Auto Park Brakefeature is disabled before towing this ve-
hicle, to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the cus-
tomer programmable features in the
Uconnect Settings.
• Vehicles with a discharged battery or total electrical failure when the electric park
brake (EPB) is engaged, will need a wheel
dolly or jack to raise the rear wheels off the
ground when moving the vehicle onto a
flatbed. If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
Note that the Safehold feature will engage
the Electric Park Brake whenever the driver's
door is opened (if the battery is connected,
ignition is ON, transmission is not in PARK,
and brake pedal is released). If you are towing
this vehicle with the ignition in the ON/RUN
mode, you must manually disable the Elec-
tric Park Brake each time the driver's door is
opened, by pressing the brake pedal and then
releasing the EPB.
If the vehicle’s battery is discharged, refer to
“Gear Selector Override” in this section for
instructions on shifting the automatic trans-
mission out of PARK so that the vehicle can
be moved.
CAUTION!
• Do not use sling-type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear
CAUTION!
suspension components. Damage to
your vehicle may result from improper
towing.
• Ensure that the Electric Park Brake is
released, and remains released, while
being towed.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Front-Wheel Drive (FWD) Models — With
Key Fob
The manufacturer recommends towing your
vehicle with all four wheels OFFthe ground
using a flatbed.
191

If flatbed equipment is not available, this
vehicle must be towed with the front wheels
OFF the ground (using a towing dolly, or
wheel lift equipment with the front wheels
raised).
Ensure that the Electric Park Brake is re-
leased, and remains released, while being
towed. The Electric Park Brake does not need
to be released, if all four wheels are off the
ground.
CAUTION!
Towing this vehicle in violation of the
above requirements can cause severe en-
gine and/or transmission damage. Damage
from improper towing is not covered under
the New Vehicle Limited Warranty.
4x4 Models
The manufacturer requires towing with all
four wheelsOFFthe ground.
Acceptable methods are to tow the vehicle on
a flatbed, or with one end of vehicle raised
and the opposite end on a towing dolly.
CAUTION!
• Front or rear wheel lifts must not be used (if the remaining wheels are on the
ground). Internal damage to the trans-
mission or power transfer unit will occur
if a front or rear wheel lift is used when
towing.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or power transfer unit
damage. Damage from improper towing
is not covered under the New Vehicle
Limited Warranty.
Recovery Strap — If Equipped
Your vehicle may be included with a recovery
strap. Recovery straps do not act like tradi-
tional tow straps, chains, or winch cables.
WARNING!
Recovery straps should only be used in
emergencies to rescue stranded vehicles.
Only use Recovery straps on vehicles that
fit within the recommended GVW of your
WARNING!
recovery strap. Only attach recovery straps
to OE recommended anchor points or
emergency towing anchor points. Never
attach to tow ball or vehicle tie down point,
these are not designed for this purpose.
Never attach to vehicle steering, drive
train, or any other suspension compo-
nents. NEVER pull a strap over sharp
edges or abrasive surfaces that can dam-
age the recovery strap. NEVER use a dam-
aged strap, it has reduced strength. DO
NOT attempt to repair straps. ONLY per-
sons involved in the recovery should be in
either vehicle. No passengers. Anyone in-
side the vehicles can be struck by strap
recoil, causing serious injury. MOVE by-
standers at least 40 ft (12.2 m) from the
recovery area when using the recovery
strap.
Using Recovery Strap
1. Review all warnings and instructions first.
2. Position the recovery vehicle.
3. Connect the recovery strap.
4. Add a recovery damper or blanket.

It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifi-
cations or capability. Failure to use equiva-
lent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
predictable handling and stress to steer-
ing and suspension components. You
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
WARNING!
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identi-
fied by the M+S, M&S, M/S or MS designa-
tion on the tire sidewall. Use all season tires
only in sets of four; failure to do so may
adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires —
If Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol
on the tire sidewall. Use Summer tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
WARNING!
Do not use Summer tires in snow/ice con-
ditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
