lug pattern JEEP CHEROKEE 2018 Owner handbook (in English)

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.
Failure to follow this warning may result in
serious injury.
10. Lower the vehicle to the ground by turn- ing 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. Refer to “Torque Specifications”
in “Technical Specifications” for the
proper lug bolt torque. If in doubt about
the correct tightness, have them
checked with a torque wrench by your
authorized dealer or at a service station.
12. Securely stow the jack, tools, chocks, and flat tire.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop could endanger the
occupants of the vehicle. Always stow the
jack parts and the spare tire in the places
provided. Have the deflated (flat) tire re-
paired or replaced immediately.
Changing Procedure
1. Mount the road tire on the axle.
2. Install the remaining wheel bolts with thethreaded end of the wheel bolt toward the
wheel. Lightly tighten the wheel bolts.
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.
Failure to follow this warning may result in
serious injury. 3. Lower the vehicle to the ground by turning
the jack handle counterclockwise.
4. 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. Re-
fer to “Torque Specifications” in “Techni-
cal Specifications” for the proper lug bolt
torque. If in doubt about the correct tight-
ness, have them checked with a torque
wrench by your authorized dealer or ser-
vice station.
5. Lower the jack until it is free. Remove the wheel chocks. Reassemble the lug wrench
to the jack assembly and stow it in the
spare tire area. Secure the assembly using
the means provided. Release the parking
brake before driving the vehicle.
6. 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.

RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride ComfortSafety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure. Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump-
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort-
able ride. Over-inflation produces a jarring
and uncomfortable ride.

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 re-
moved and reinstalled on the vehicle, the lug
nuts/bolts should be torqued using a properly
calibrated torque wrench using a high quality
six sided (hex) deep wall socket.
Torque Specifications

Size Lug Nut/Bolt
Socket Size
100 Ft-Lbs (135 N·m) M12 x 1.25 19 mm
**Use only an authorized dealer recom-
mended 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 halfway).
After 25 miles (40 km), check the lug nut/
bolt torque to be sure that all the lug nuts/
bolts are properly seated against the wheel.
WARNING!
To avoid the risk of forcing the vehicle off
the jack, do not tighten the lug nuts fully
until the vehicle has been lowered. Failure
to follow this warning may result in per-
sonal injury.
FUEL REQUIREMENTS —
GASOLINE ENGINE
This engine is designed to meet all emissions
regulations and provide excellent fuel
economy and performance when using high
quality unleaded gasoline with a minimum
research octane rating (RON) of 91.
Light spark knock at low engine speeds is not
harmful to your engine. However, continued
heavy spark knock at high speeds can cause
damage, and immediate service is required.
Poor quality gasoline can cause problems
such as hard starting, stalling, and hesita-
tions. If you experience these symptoms, try
another brand of gasoline before considering
service for the vehicle.
