2023 JEEP GRAND CHEROKEE air suspension

IN CASE OF EMERGENCY327
NOTE:
You must ensure that the Auto Park Brake
Úpage 123 feature is disabled before towing
this vehicle to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the customer
programmable features in the Uconnect
Settings.
Vehicles with a discharged battery, or total elec -
trical 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.
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 Electric Park Brake each
time the driver's door is opened by pressing the
brake pedal and then releasing the EPB. If you must use the accessories (wipers,
defrosters, etc.) while being towed, the ignition
must be in the ON/RUN mode.
If the vehicle's battery is discharged, instructions
on shifting the automatic transmission out of PARK
(P) in order to move the vehicle Ú
page 323.
REAR-WHEEL DRIVE MODELS
FCA US LLC recommends towing your vehicle with
all four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be towed
(with rear wheels off the ground) under the
following conditions:
The transmission must be in NEUTRAL (N). For
instructions on shifting the transmission to
NEUTRAL (N) when the engine is off
Ú page 323.
The towing speed must not exceed 30 mph
(48 km/h).
The towing distance must not exceed 30 miles
(48 km).
CAUTION!
Do not use sling type equipment when towing.
Vehicle damage may occur.
When securing the vehicle to a flat bed truck,
do not attach to front or rear suspension
components. If vehicle is equipped with
Quadra-lift air suspension, secure vehicle only
with tire/wheel straps (no suspension compo -
nents or body) to prevent air suspension from
adjusting during towing against securement
straps and causing damage. Damage to your
vehicle may result from improper towing.
CAUTION!
Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe trans -
mission damage. Damage from improper
towing is not covered under the New Vehicle
Limited Warranty.

SERVICING AND MAINTENANCE385
NOTE:Wheel valve stem must be replaced as well when
installing new tires due to wear and tear in existing
tires.
Keep dismounted tires in a cool, dry place with as
little exposure to light as possible. Protect tires
from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of
many characteristics. They should be inspected
regularly for wear and correct cold tire inflation
pressures. The manufacturer strongly
recommends using tires equivalent to the originals
in size, quality and performance when
replacement is needed Úpage 384. Refer to the
Tire And Loading Information Placard or the
Vehicle Certification Label for the size designation
of your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
See the Tire Sizing Chart example found in the “Tire
Safety Information” section of this manual for
more information relating to the Load Index and
Speed Symbol of a tire.
It is recommended to replace the two front tires or
two rear tires as a pair. Replacing just one tire can
seriously affect your vehicle’s handling. If you ever
replace a wheel, make sure that the wheel’s
specifications match those of the original wheels. It is recommended you contact an authorized tire
dealer or original equipment dealer with any
questions you may have on tire specifications or
capability. Failure to use equivalent replacement
tires may adversely affect the safety, handling, and
ride of your vehicle.
TIRE TYPES
All Season Tires — If Equipped
All Season tires provide traction for all seasons
(Spring, Summer, Autumn, and Winter). Traction
levels may vary between different all season tires.
All season tires can be identified by the M+S, M&S,
M/S or MS designation 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.
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 performance characteristics,
resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpre
-
dictable handling and stress to steering 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 originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire over -
loading 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 speedometer and
odometer readings.
