warning JEEP GRAND CHEROKEE 2023 Owners Manual

394SERVICING AND MAINTENANCE
If you carry special cargo such as chemicals,
fertilizers, de-icer salt, etc., be sure that such
materials are well packaged and sealed.
If a lot of driving is done on gravel roads,
consider mud or stone shields behind each
wheel.
Use Mopar® Touch Up Paint on scratches as
soon as possible. An authorized dealer has
touch up paint to match the color of your
vehicle.
INTERIORS
SEATS AND FABRIC PARTS
Use Mopar® Total Clean to clean fabric upholstery
and carpeting.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the
fabric. Sun damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution
or lukewarm water. Do not remove the belts from
the vehicle to wash them. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or
if the buckles do not work properly.
PLASTIC AND COATED PARTS
Use Mopar® Total Clean to clean vinyl upholstery.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable, and
if used in closed areas they may cause
respiratory harm.
WARNING!
A frayed or torn seat belt could rip apart in a
collision and leave you with no protection.
Inspect the seat belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the seat belt
system. If your vehicle is involved in a collision,
or if you have questions regarding seat belt or
retractor conditions, take your vehicle to an
authorized FCA dealer or authorized FCA
Certified Collision Care Program facility for
inspection.
CAUTION!
Direct contact of air fresheners, insect repel -
lents, suntan lotions, or hand sanitizers to the
plastic, painted, or decorated surfaces of the
interior may cause permanent damage. Wipe
away immediately.
Damage caused by these type of products
may not be covered by your New Vehicle
Limited Warranty.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on a label located on the left front
corner of the instrument panel pad, visible from
outside of the vehicle through the windshield.
Windshield VIN Label Location

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 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.

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/bolt
(do not insert it half way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by an authorized
dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly tightened.

FUEL REQUIREMENTS
While operating on gasoline with the required
octane number, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see a dealer immediately. Use of
gasoline with an octane number lower than
recommended can cause engine failure and may
void the New Vehicle Limited Warranty.
Poor quality gasoline can cause problems such as
hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand of
gasoline before considering service for the vehicle.
2.0L ENGINE
This engine is designed to meet all
emissions requirements, and provide
satisfactory fuel economy and
performance, when using high-quality
unleaded regular gasoline having an octane rating
of 87, as specified by the (R+M)/2 method. The
use of 91 or higher octane premium gasoline will
allow these engines to operate to optimal
performance. This increase in performance is most
noticeable in hot weather or under heavy load
conditions, such as while towing.
3.6L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emissions regulations and provide
optimum fuel economy and performance
when using high quality unleaded regular
gasoline having a posted octane number of 87 as
specified by the (R+M)/2 method. The use of
higher octane premium gasoline is not required, as
it will not provide any benefit over regular gasoline
in these engines.
5.7L ENGINE
Do not use E-85 flex fuel or ethanol blends greater
than 15% in this engine.
This engine is designed to meet all
emission regulations and provide
satisfactory fuel economy and
performance when using high-quality
unleaded gasoline having an octane range of 87 to
89 as specified by the (R+M)/2 method. The use of
89 octane plus gasoline is recommended for
optimum performance and fuel economy.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully until
the vehicle has been lowered. Failure to follow
this warning may result in personal injury.

ASHINGTON, D.C.
If you believe that your vehicle has a
defect that could cause a crash or cause
injury or death, you should immediately
inform the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying FCA US LLC.
If NHTSA receives similar complaints, it
may open an investigation, and if it finds
that a safety defect exists in a group of
vehicles, it may order a recall and
remedy campaign. However, NHTSA
cannot become involved in individual
problems between you, an authorized
dealer or FCA US LLC.
WARNING!
Engine exhaust (internal combustion engines
only), some of its constituents, and certain
vehicle components contain, or emit, chemicals
known to the State of California to cause cancer
and birth defects, or other reproductive harm. In
addition, certain fluids contained in vehicles and
certain products of component wear contain, or
emit, chemicals known to the State of California
to cause cancer and birth defects, or other
reproductive harm.
