2020 JEEP WRANGLER warning

WARNING!
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identified
by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in
sets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
Summer Or Three Season Tires — If
Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol
on the tire sidewall. Use Summer tires only insets of four; failure to do so may adversely
affect the safety and handling of your vehicle.
WARNING!
Do not use Summer tires in snow/ice con-
ditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can
be identified by a “mountain/snowflake”
symbol on the tire sidewall.
If you need snow tires,
select tires equivalent
in size and type to the
original equipment
tires. Use snow tires
only in sets of four;
failure to do so may
adversely affect the
safety and handling of your vehicle.
197

Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at sus-
tained speeds over 75 mph (120 km/h). For
speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire
dealer for recommended safe operating
speeds, loading and cold tire inflation pres-
sures.
While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of non-
studded tires. Some states prohibit studded
tires; therefore, local laws should be checked
before using these tire types.
Spare Tires — If Equipped
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “In Case Of Emergency” in
the Owner’s Manual for further information.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an auto-

the vehicle may result.
Spare Tire Matching Original Equipped Tire
And Wheel — If Equipped
Your vehicle may be equipped with a spare
tire and wheel equivalent in look and func-
tion to the original equipment tire and wheel
found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rota-
tion for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for
the recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emer-
gency use only. You can identify if your ve-
hicle is equipped with a compact spare by
looking at the spare tire description on the
Tire and Loading Information Placard located
on the driver’s side door opening or on thesidewall of the tire. Compact spare tire de-
scriptions begin with the letter “T” or “S”
preceding the size designation. Example:
T145/80D18 103M.
T,S=Temporary Spare Tire
Since this tire has limited tread life, the
original equipment tire should be repaired (or
replaced) and reinstalled on your vehicle at
the first opportunity.
Do not install a wheel cover or attempt to
mount a conventional tire on the compact
spare wheel, since the wheel is designed
specifically for the compact spare tire. Do not
install more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact and collapsible spares are for tem-
porary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have lim-
ited tread life. When the tread is worn to the
tread wear indicators, the temporary use
spare tire needs to be replaced. Be sure to
follow the warnings, which apply to your

spare. Failure to do so could result in spare
tire failure and loss of vehicle control.
Full Size Spare — If Equipped
The full size spare is for temporary emer-
gency use only. This tire may look like the
originally equipped tire on the front or rear
axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the
tread is worn to the tread wear indicators, the
temporary use full size spare tire needs to be
replaced. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by
a label located on the limited use spare
wheel. This label contains the driving limita-
tions for this spare. This tire may look like the
original equipped tire on the front or rear axle
of your vehicle, but it is not. Installation of
this limited use spare tire affects vehiclehandling. Since it is not the same as your
original equipment tire, replace (or repair)
the original equipment tire and reinstall on
the vehicle at the first opportunity.
WARNING!
Limited use spares are for emergency use
only. Installation of this limited use spare
tire affects vehicle handling. With this tire,
do not drive more than the speed listed on
the limited use spare wheel. Keep inflated
to the cold tire inflation pressures listed on
your Tire and Loading Information Placard
located on the driver’s side B-Pillar or the
rear edge of the driver’s side door. Replace
(or repair) the original equipment tire at
the first opportunity and reinstall it on your
vehicle. Failure to do so could result in loss
of vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially alumi-
num and chrome plated wheels, should be
cleaned regularly using mild (neutral Ph)
soap and water to maintain their luster and to
prevent corrosion. Wash wheels with thesame soap solution recommended for the
body of the vehicle and remember to always
wash when the surfaces are not hot to the
touch.
Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other
road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge
and mild soap to wipe away promptly. Do not
use harsh chemicals or a stiff brush. They can
damage the wheel’s protective coating that
helps keep them from corroding and
tarnishing.
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, Mopar Wheel Cleaner or
equivalent is recommended.
199

When cleaning extremely dirty wheels includ-
ing excessive brake dust, care must be taken
in the selection of tire and wheel cleaning
chemicals and equipment to prevent damage
to the wheels. Mopar Wheel Treatment or
Mopar Chrome Cleaner or their equivalent is
recommended or 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, Mopar
Wheel Cleaner or equivalent 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 WheelsCAUTION!
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.
• Install on Rear Tires Only.
• A 235/65R17 tire with the use of a traction
device that meets the SAE type “Class S”
specification is recommended.
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-

CAUTION!
immediately and thoroughly as the acid
they contain is particularly aggressive.
• Avoid (if at all possible) parking the
vehicle under trees; remove vegetable
resins immediately as, when dried, it
may only be possible to remove them
with abrasive products and/or polishes,
which is highly inadvisable as they could
alter the typical opaqueness of the
paint.
• Do not use pure windshield washer fluid
for cleaning the front windshield and
rear window; dilute it min. 50% with
water. Only use pure windshield washer
fluid when strictly necessary due to out-
side temperature conditions.
Care Of Fabric Top Windows
Your vehicle's fabric top has pliable plastic
windows which can be scratched unless spe-
cial care is taken by following these directions:
1. Never use a dry cloth to remove dust.
Instead,use a microfiber towel or soft cot-
ton cloth moistened with cold or warm,clean water, and wipe across the window,
not up and down.
2. When washing,never use hot wateror any-
thing stronger than a mild soap. Never use
solvents such as alcohol or harsh cleaning
agents.
3. Always rinse thoroughly with cold water,
then wipe with a soft and slightly moist,
clean cloth.
4. When removing frost, snow or ice,never
use a scraper or de-icing chemicals.Use
warm water only if you must clean the
window quickly.
5. Debris (sand, mud/dirt, dust, or salt) from
off-road driving will have a major impact
on zipper operation. Even normal on-road
driving and vehicle washing will eventu-
ally impact window zipper operation. To
maintain ease of use of the window zip-
pers, each window zipper should be
cleaned and lubricated regularly. Before
applying, make sure the zipper teeth are
clear of sand, mud, and other materials.
Clean both sides of the zipper, not justone side. Rinse both zipper halves with
fresh water and allow to dry. Several ap-
plications may be required before the zip-
per comes free.
6. Never paste stickers, gummed labels or
any tape to the windows. Adhesives are
hard to remove and may damage the
windows.
INTERIORS
Seats And Fabric Parts
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flam-
mable, and if used in closed areas they
may cause respiratory harm.
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.
SERVICING AND MAINTENANCE
204

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.
WARNING!
A frayed or torn belt could rip apart in a
collision and leave you with no protection.
Inspect the belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immedi-
ately. Do not disassemble or modify the
system. Seat belt assemblies must be re-
placed after a collision if they have been
damaged (i.e., bent retractor, torn web-
bing, etc.).
Plastic And Coated Parts
Use Mopar Total Clean to clean vinyl
upholstery.
CAUTION!
•Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sanitiz-
ers to the plastic, painted, or decorated
surfaces of the interior may cause perma-
nent damage. Wipe away immediately.
• Damage caused by these type of prod-
ucts may not be covered by your New
Vehicle Limited Warranty.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When
cleaning the lenses, care must be taken to
avoid scratching the plastic.
1. Clean with a wet soft cloth. A mild soap
solution may be used, but do not use high
alcohol content or abrasive cleaners. If
soap is used, wipe clean with a clean
damp cloth.
2. Dry with a soft cloth.
Leather Parts
Your leather upholstery can be best preserved
by regular cleaning with a damp soft cloth.
Small particles of dirt can act as an abrasive
and damage the leather upholstery and should
be removed promptly with a damp cloth. Care
should be taken to avoid soaking your leather
upholstery with any liquid. Please do not use
polishes, oils, cleaning fluids, solvents, deter-
gents, or ammonia-based cleaners to clean
your leather upholstery. Application of a
leather conditioner is not required to maintain
the original condition.
NOTE:
If equipped with light colored leather, it tends
to show any foreign material, dirt, and fabric
dye transfer more so than darker colors. The
leather is designed for easy cleaning.
CAUTION!
Do not use Alcohol and Alcohol-based
and/or Ketone based cleaning products to
clean leather seats, as damage to the seat
may result.

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 ENGINES
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.
Ethanol
The manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 15% ethanol. Purchasing your fuel from
a reputable supplier may reduce the risk of
exceeding this 15% limit and/or of receiving
fuel with abnormal properties. It should also
be noted that an increase in fuel consump-tion should be expected when using ethanol-
blended fuels, due to the lower energy con-
tent of ethanol. Problems that result from
using methanol/gasoline or E-85 ethanol
blends are not the responsibility of the
manufacturer.
CAUTION!
Use of fuel with Ethanol content higher
than 15% may result in engine malfunc-
tion, starting and operating difficulties,
and materials degradation. These adverse
effects could result in permanent damage
to your vehicle.
FUEL REQUIREMENTS —
DIESEL ENGINES
Use Premium Quality Diesel fuels with a
Cetane rating of 50 or higher, and meeting
the EN590 standard are highly recom-
mended. See your authorized dealer for fur-
ther information regarding fuels available in
your area.

CYBERSECURITY
Your vehicle may be a connected vehicle and
may be equipped with both wired and wire-
less networks. These networks allow your
vehicle to send and receive information. This
information allows systems and features in
your vehicle to function properly.
Your vehicle may be equipped with certain
security features to reduce the risk of unau-
thorized and unlawful access to vehicle sys-
tems and wireless communications. Vehicle
software technology continues to evolve over
time and FCA US LLC, working with its sup-
pliers, evaluates and takes appropriate steps
as needed. Similar to a computer or other
devices, your vehicle may require software
updates to improve the usability and perfor-
mance of your systems or to reduce the po-
tential risk of unauthorized and unlawful ac-
cess to your vehicle systems.
The risk of unauthorized and unlawful access
to your vehicle systems may still exist, even if
the most recent version of vehicle software
(such as Uconnect software) is installed.
WARNING!
• It is not possible to know or to predict all
of the possible outcomes if your vehi-
cle’s systems are breached. It may be
possible that vehicle systems, including
safety related systems, could be im-
paired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
• ONLY insert media (e.g., USB, SD card,
or CD) into your vehicle if it came from a
trusted source. Media of unknown origin
could possibly contain malicious soft-
ware, and if installed in your vehicle, it
