2018 JEEP CHEROKEE tires

• You can use the Tire Service Kit air pump toinflate bicycle tires. The kit also comes with
two needles, located in the Accessory Stor-
age Compartment (on the bottom of the air
pump) for inflating sport balls, rafts, or
similar inflatable items. However, use only
the Air Pump Hose (7) and make sure the
Mode Select Knob (5) is in the Air Mode
when inflating such items to avoid injecting
sealant into them. The Tire Service Kit
Sealant is only intended to seal punctures
less than 1/4 inch (6 mm) diameter in the
tread of your vehicle.
• Do not lift or carry the Tire Service Kit by the hoses.
WARNING!
•Do not attempt to seal a tire on the side of
the vehicle closest to traffic. Pull far
enough off the road to avoid the danger of
being hit when using the Tire Service Kit.
•Do not use Tire Service Kit or drive the
vehicle under the following circumstances:
– If the puncture in the tire tread is
approximately 1/4 inch (6 mm) or
larger.
WARNING!
– If the tire has any sidewall damage.
– If the tire has any damage fromdriving with extremely low tire pres-
sure.
– If the tire has any damage from
driving on a flat tire.
– If the wheel has any damage.
– If you are unsure of the condition of
the tire or the wheel.
• Keep Tire Service Kit away from open
flames or heat source.
• A loose Tire Service Kit thrown forward
in a collision or hard stop could endan-
ger the occupants of the vehicle. Always
stow the Tire Service Kit in the place
provided. Failure to follow these warn-
ings can result in injuries that are seri-
ous or fatal to you, your passengers, and
others around you.
• Take care not to allow the contents of
Tire Service Kit to come in contact with
hair, eyes, or clothing. Tire Service Kit
sealant is harmful if inhaled, swallowed,
or absorbed through the skin. It causes
skin, eye, and respiratory irritation.
WARNING!
Flush immediately with plenty of water if
there is any contact with eyes or skin.
Change clothing as soon as possible, if
there is any contact with clothing.
• Tire Service Kit Sealant solution con-
tains latex. In case of an allergic reac-
tion or rash, consult a physician imme-
diately. Keep Tire Service Kit out of
reach of children. If swallowed, rinse
mouth immediately with plenty of water
and drink plenty of water. Do not induce
vomiting! Consult a physician immedi-
ately.
Sealing A Tire With Tire Service Kit
(A) Whenever You Stop To Use Tire Service
Kit:
1. Pull over to a safe location and turn on the
vehicle’s Hazard Warning flashers.
2. Verify that the valve stem (on the wheel with the deflated tire) is in a position that
is near to the ground. This will allow the
Tire Service Kit Hoses (6) and (7) to reach
the valve stem and keep the Tire Service
IN CASE OF EMERGENCY

GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position,
you can use the following procedure to tem-
porarily move the gear selector:
1. Turn the engine OFF.
2. Apply the parking brake.
3. Using a screwdriver or similar tool, care-fully separate the shifter bezel and boot
assembly from the center console, and
raise it up to access the gear selector
mechanism.
4. Press and maintain firm pressure on the brake pedal.
5. Insert a small screwdriver or similar tool down into the gear selector override ac-
cess hole (at the left front corner of the
gear selector assembly), and push and
hold the override release lever down.
6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector boot.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or
snow, it can often be moved using a rocking
motion. Turn the steering wheel right and left
to clear the area around the front wheels. For
vehicles with automatic transmission, push
and hold the lock button on the gear selector.
Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or
SECOND GEAR and REVERSE (with manual
transmission), while gently pressing the ac-
celerator.
NOTE:
For vehicles with automatic transmission:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.
CAUTION!
• Racing the engine or spinning the wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing between DRIVE/SECOND GEAR and
REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
189

NOTE:
Push the “ESC Off” switch (if necessary), to
place the Electronic Stability Control (ESC)
system in “Partial Off” mode, before rocking
the vehicle. Refer to “Electronic Brake Con-
trol System” in “Safety” for further informa-
tion. Once the vehicle has been freed, push
the "ESC Off" switch again to restore “ESC
On” mode.WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your
vehicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.

SCHEDULED SERVICING
Scheduled Servicing — Gasoline Engine
The scheduled services listed in this manual
must be done at the times or mileages speci-
fied to protect your vehicle warranty and
ensure the best vehicle performance and re-
liability. More frequent maintenance may be
needed for vehicles in severe operating con-
ditions, such as dusty areas and very short
trip driving. Inspection and service should
also be done anytime a malfunction is sus-
pected.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
An “Oil Change Required” will be displayed
in the instrument cluster and a single chime
will sound, indicating that an oil change is
necessary.
The oil change indicator message will illumi-
nate approximately 7,000 miles (11,200 km)
after the most recent oil change was per-
formed. Have your vehicle serviced as soon as
possible, within 500 miles (800 km).
NOTE:
• The oil change indicator message will notmonitor the time since the last oil change.
Change your vehicle’s oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you drive your vehicle off-road for an extended
period of time.
• Under no circumstances should oil change intervals exceed 7,500 miles (12,000 km)
or 12 months, whichever comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If this scheduled
oil change is performed by someone other
than your authorized dealer the message can
be reset by referring to the steps described
under ”Instrument Cluster Display” in “Get-
ting To Know Your Instrument Panel” for
further information. Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
• Check the fluid levels of the coolant reser- voir and brake master cylinder, fill as
needed.
• Check function of all interior and exterior lights.
