2018 JEEP CHEROKEE snow chains

Should this occur, you should stop as soon as
possible and inflate the tires with low pres-
sure (those in a different color in the instru-
ment cluster graphic) to the vehicle’s recom-
mended cold placard pressure value. Once
the system receives the updated tire pres-
sures, the system will automatically update,
the pressure values in the graphic display in
the instrument cluster will return to their
original color, and the “Tire Pressure Monitor-
ing Telltale Light” will turn off.NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold plac-
ard pressure in order to turn the Tire Pressure
Monitoring Telltale Light off. The vehicle may
need to be driven for up to 10 minutes above
15 mph (24 km/h) in order for the TPMS to
receive this information.
Service TPMS Warning
When a system fault is detected, the “Tire
Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds and then remain on
solid. The system fault will also sound a
chime. In addition, the instrument cluster
will display a "SERVICE TPM SYSTEM" mes-
sage for a minimum of five seconds and then
display dashes (- -) in place of the pressure
value to indicate which sensor is not being
received.
If the ignition key is cycled, this sequence
will repeat, providing the system fault still
exists. If the system fault no longer exists, the
“Tire Pressure Monitoring Telltale Light” will
no longer flash, and the “SERVICE TPM SYS-
TEM” message will no longer display, and a
pressure value will display in place of the
dashes. A system fault can occur due to any
of the following:
• Jamming due to electronic devices or driv-
ing next to facilities emitting the same
radio frequencies as the TPMS sensors.
• Installing some form of aftermarket window tinting that affects radio wave signals.
• Lots of snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare or Non-Matching
Full Size Spare
1. The compact spare tire or non-matching full size does not have a tire pressure
monitoring sensor. Therefore, the TPMS
will not monitor the pressure in the com-
pact spare tire.
2. If you install the compact or non- matching full size spare tire in place of a
road tire that has a pressure below the
low-pressure warning limit, upon the next

CAUTION!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. Many aftermar-
ket wheel cleaners and automatic car
washes may damage the wheel's protective
finish. Such damage is not covered by the
New Vehicle Limited Warranty. Only car
wash soap is recommended.
When cleaning extremely dirty wheels includ-
ing excessive brake dust, care must be taken in
the selection of tire and wheel cleaning chemi-
cals and equipment to prevent damage to the
wheels. Select a non-abrasive, non-acidic
cleaner for aluminum or chrome wheels.
CAUTION!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven
cleaner. These products may damage the
wheel's protective finish. Such damage is
not covered by the New Vehicle Limited
Warranty. Only car wash soap is recom-
mended.NOTE:
If you intend parking or storing your vehicle
for an extended period after cleaning the
wheels with wheel cleaner, drive your vehicle
and apply the brakes to remove the water
droplets from the brake components. This
activity will remove the red rust on the brake
rotors and prevent vehicle vibration when
braking.
Dark Vapor Chrome, Black Satin Chrome, or Low
Gloss Clear Coat Wheels
CAUTION!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing com-
pounds. They will permanently damage
this finish and such damage is not covered
by the New Vehicle Limited Warranty.
HAND WASH ONLY USING MILD SOAP
AND WATER WITH A SOFT CLOTH. Used
on a regular basis; this is all that is re-
quired to maintain this finish.
Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-
to-body clearance. Follow these recommen-
dations to guard against damage.
• Traction device must be of proper size for
the tire, as recommended by the traction
device manufacturer
• Use on Front Tires Only
• Due to limited clearance, the following traction devices are recommended:
Front Wheel Drive (FWD) Models
• Original equipment 225/60R17 and 225/ 55R18 tire sizes are not chainable.
• The use of 7mm snow chains is permitted with the use of 215/60R17 tires on size
17 x 7.0 ET41 wheels.
Four Wheel Drive (4WD) Non-Trailhawk Models
Without A Two-Speed Power Takeoff Unit
• Original equipment 225/60R17 and 225/ 55R18 tire sizes are not chainable.
• The use of 9mm snow chains is permitted with the use of 215/60R17 tires on size
17 x 7.0 ET41 wheels.
223

Four Wheel Drive (4WD) Non-Trailhawk Models
With A Two-Speed Power Takeoff Unit
• The use of 7mm snow chains is permittedwith 225/60R17 and 225/55R18 tires.
Four Wheel Drive (4WD) Trailhawk Models
• The use of 9mm snow chains is permitted with the use of 225/65R17 tires on size
17 x 7.5 ET31 wheels.
CAUTION!
• Use on Front Tires Only
• Damage to Front Wheel Drive (FWD) Models may result if tire chains or trac-
tion devices are used with original
equipment size tires.
• Damage to Four Wheel Drive (4WD)
Models without a Two-Speed Power
Takeoff Unit may result if tire chains or
traction devices are used with original
equipment size tires.
• Damage to Four Wheel Drive (4WD)
Trailhawk Models may result if tire
chains or traction devices are used with
original equipment size tires.
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 deviceclearance 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 typeSERVICING AND MAINTENANCE
