wheel size JEEP CHEROKEE 2019 Owner handbook (in English)

WARNING!
Using tires of different size and type
(M+S, Snow) between front and rear axles
can cause unpredictable handling. You
could lose control and have a collision.
CAUTION!
To avoid damage to your vehicle or tires,
observe the following precautions:
• Because of restricted traction device
clearance between tires and other sus-
pension components, it is important
that only traction devices in good condi-
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately if noise occurs that could indi-
cate device breakage. Remove the dam-
aged parts of the device before further
use.
• Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
CAUTION!
• Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
• Do not drive for a prolonged period on
dry pavement.
• Observe the traction device manufactur-
er’s instructions on the method of instal-
lation, operating speed, and conditions
for use. Always use the suggested oper-
ating speed of the device manufacturer’s
if it is less than 30 mph (48 km/h).
• Do not use traction devices on a com-
pact spare tire.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform differ-
ent steering, handling, and braking func-
tions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rota-
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off Road typetires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels,
and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested Front Wheel Drive (FWD) rota-
tion method is the “forward cross” shown in
the following diagram. This rotation pattern
does not apply to some directional tires that
must not be reversed.
The suggested Four Wheel Drive (4WD) Tire
rotation method is the “rearward cross”
shown in the following diagram.

CAUTION!
Proper operation of four-wheel drive ve-
hicles depends on tires of equal size, type
and circumference on each wheel. Any
difference in tire size can cause damage to
the power transfer unit. Tire rotation
schedule should be followed to balance
tire wear.
STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
• Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.• Check that the Electric Park Brake is not
engaged.
• Disconnect the negative (-) terminal from
the battery post and be sure that the battery
is fully charged. During storage check bat-
tery charge quarterly.
• If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
• Clean and protect the painted parts by
applying protective waxes.
• Clean and protect polished metal parts by
applying protective waxes.
• Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.
• Cover the vehicle with an appropriate cover
taking care not to damage the painted sur-
face by dragging across dirty surfaces. Do
not use plastic sheeting which will not allow
the evaporation of moisture present on the
surface of the vehicle.
• Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.• Do not drain the engine cooling system.
• Whenever you leave the vehicle stationary
for two weeks or more, idle the engine for
approximately five minutes, with the air
conditioning system on and high fan speed.
This will ensure proper lubrication of the
system, thus minimizing the possibility of
damage to the compressor when the vehicle
is put back into operation.
NOTE:
When the vehicle has not been started or
driven for at least 30 days, an Extended Park
Start Procedure is required to start the ve-
hicle.
Refer to “Starting The Engine” in “Starting
And Operating” for further information.
CAUTION!
Before removal of the positive and nega-
tive terminals to the battery, wait at least a
minute with ignition switch in the OFF
position and close the driver’s door. When
reconnecting the positive and negative ter-
minals to the battery be sure the ignition
switch is in the OFF position and the
driver’s door is closed.

calibrated torque wrench using a high quality
six sided (hex) deep wall socket.

**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/bolts
fully until the vehicle has been lowered.
Failure to follow this warning may result in
personal 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.
