tow JEEP WRANGLER UNLIMITED 2018 Owner handbook (in English)

**** The spark plug change interval is mile-
age based only, yearly intervals do not apply.
***** This maintenance is recommended by
the manufacturer to the owner, but is not
required to maintain emissions warranty.
WARNING!
• You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
Severe Duty Conditions
Change the engine oil and engine oil filter at
every 4500 miles (7,500 km) or 6 months if
using your vehicle under any of the following
severe duty conditions:• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.
• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
Scheduled Servicing — Diesel Engine
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for engine oil
replacement.
On vehicles equipped with instrument cluster
display, “Oil Change Required” will be dis-
played and a single chime will sound, indi-
cating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the instru-
ment cluster odometer and a single chime
will sound, indicating that an oil change is
necessary.Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed. Severe Operating Conditions can
cause the change oil message to illuminate
as earlier than specified. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).
NOTE:
•The actual interval for changing engine oil
and replacing the engine oil filter depends on
the vehicle usage conditions, and is signaled
by the warning light or message in the instru-
ment cluster. In any case, it must never ex-
ceed two years. If the vehicle is used mainly
for city driving, change the engine oil and
filter every year.
•Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.

Checking Oil Level — Gasoline Engine
WARNING!
• Never smoke while working in the engine
compartment: gas and inflammable va-
pors may be present, with the risk of fire.
• Be very careful when working in the
engine compartment when the engine is
hot: you may get burned. Do not get too
close to the radiator cooling fan: the
electric fan may start; danger of injury.
Scarves, ties and other loose clothing
might be pulled by moving parts.
CAUTION!
• Be careful not to confuse the various
types of fluids while topping up: they are
not compatible with each other! Topping
up with an unsuitable fluid could se-
verely damage your car.
• The oil level must never exceed the MAX
mark.
• Always top up using engine oil of the
same specifications as that already in
the engine.
CAUTION!
• If the engine oil is being topped up, wait
for the engine to cool down before loos-
ening the filler cap, particularly for ve-
hicles with aluminium cap (if
equipped). WARNING: risk of burns!
• Overfilling or underfilling the crankcase
will cause aeration or loss of oil pres-
sure. This could damage your engine.
To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. The engine oil level should
be checked five minutes after a warmed up
engine has been shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Always maintain the oil level
within the SAFE zone on the dipstick. Adding
1 quart (0.95 liters) of oil when the reading is
at the bottom of the crosshatch zone will
result in a reading at the top of the cross-
hatch zone on these engines.
Adding Washer Fluid
The fluid reservoir for the windshield washers
and the rear window washer (if equipped) is
shared. The fluid reservoir is located in the
engine compartment. Be sure to check the
fluid level at regular intervals. Fill the reser-
voir with windshield washer solvent only (not
radiator antifreeze). When refilling the
washer fluid reservoir, take some washer fluid
and apply it to a cloth or towel and wipe clean
the wiper blades; this will help blade perfor-
mance.
To prevent freeze-up of your windshield
washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the
temperature range of your climate. This rat-
ing information can be found on most washer
fluid containers.
WARNING!
Commercial windshield washer solvents
are flammable. They could ignite and burn
you. Care must be exercised when filling or
working around the washer solution.

(6) If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and lug-
gage load capacity of your vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg
and there will be five 68 kg passengers in
your vehicle, the amount of available cargo
and luggage load capacity is 295 kg (635-
340 (5x68) = 295 kg) as shown in step 4.
NOTE:
• If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle. The following table shows ex-
amples on how to calculate total load,
cargo/luggage, and towing capacities of
your vehicle with varying seating configura-
tions and number and size of occupants.
This table is for illustration purposes only
and may not be accurate for the seating and
load carry capacity of your vehicle.• For the following example, the combined
weight of occupants and cargo should never
exceed 865 lbs (392 kg).

reduced vehicle loading may be required for
high-speed vehicle operation. Refer to an
authorized tire dealer or original equipment
vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation
pressures.
WARNING!
High speed driving with your vehicle under
maximum load is dangerous. The added
strain on your tires could cause them to
fail. You could have a serious collision. Do
not drive a vehicle loaded to the maximum
capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability
could cause a collision. Always use radial
ply tires in sets of four. Never combine
them with other types of tires.Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
• The tire has not been driven on when flat.
• The damage is only on the tread section of
your tire (sidewall damage is not repair-
able).
• The puncture is no greater thana¼ofan
inch (6 mm).
Consult an authorized tire dealer for tire re-
pairs and additional information.
Damaged Run Flat tires, or Run Flat tires that
have experienced a loss of pressure should be
replaced immediately with another Run Flat
tire of identical size and service description
(Load Index and Speed Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive
50 miles (80 km) at 50 mph (80 km/h) after
a rapid loss of inflation pressure. This rapid
loss of inflation is referred to as the Run Flat
mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi
(96 kPa). Once a Run Flat tire reaches therun flat mode it has limited driving capabili-
ties and needs to be replaced immediately. A
Run Flat tire is not repairable.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer while
a tire is in the run flat mode.
See the tire pressure monitoring section for
more information.
Tire Spinning
When stuck in mud, sand, snow, or ice con-
ditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” in your Owner’s Manual
for further information.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than

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 direc-
tions:
• Never use a dry cloth to remove dust. In-
stead,use a microfiber towel or soft cotton
cloth moistened with cold or warm, clean
water, and wipe across the window, not up
and down.It removes fine scratches to im-
prove visibility and provides UV protection
to help prevent yellowing.
• When washing,never use hot wateror any-
thing stronger than a mild soap. Never use
solvents such as alcohol or harsh cleaning
agents.
• Always rinse thoroughly with cold water,
then wipe with a soft and slightly moist,
clean cloth.
• 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.•
Debris (sand, mud/dirt, dust, or salt) from
off-road driving will have an impact on plas-
tic retainer operation. Even normal on-road
driving and vehicle washing will eventually
impact window plastic retainer operation. To
maintain ease of use of the window plastic
retainers, each window plastic retainer
should be cleaned and lubricated regularly.
Clean them with a mild soap solution and a
small brush. Cleaning products are available
through an authorized dealer.
• 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
Use a specific product to clean fabric uphol-
stery and carpeting.
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.
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.).SERVICING AND MAINTENANCE

upholstery.
CAUTION!
• Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sani-
tizers to the plastic, painted, or deco-
rated surfaces of the interior may cause
permanent damage. Wipe away immedi-
ately.
• 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, detergents, or ammonia-
based cleaners to clean your leather uphol-
stery. Application of a leather conditioner is
not required to maintain the original condi-
tion.
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.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with any commercial
household-type glass cleaner. Never use an
abrasive type cleaner. Use caution when
cleaning the inside rear window equipped
with electric defrosters or windows equipped
with radio antennas. Do not use scrapers or
other sharp instruments that may scratch the
elements.
