Care Of Fabric Top Windows
Your vehicle's fabric top has pliable plastic
windows which can be scratched unless
special care is taken by following these
directions:
Never use a dry cloth to remove dust.
Instead, 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 improve visibility and provides UV
protection to help prevent yellowing.
When washing, never use hot water or
anything 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
plastic 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.
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.
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
outside temperature conditions.
CAUTION! (Continued)
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable,
and if used in closed areas they may cause
respiratory harm.

SERVICING AND MAINTENANCE
246
Plastic And Coated Parts
Use a specific product to clean vinyl uphol-
stery.
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 uphol -
stery 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 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.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with any commercial house
-
hold-type glass cleaner. Never use an abra -
sive type cleaner. Use caution when cleaning
the inside rear window equipped with elec -
tric defrosters or windows equipped with
radio antennas. Do not use scrapers or other
sharp instruments that may scratch the
elements.
When cleaning the rear view mirror, spray
cleaner on the towel or cloth that you are
using. Do not spray cleaner directly on the
mirror.
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
immediately. Do not disassemble or modify
the system. Seat belt assemblies must be
replaced after a collision if they have been
damaged (i.e., bent retractor, torn
webbing, etc.).
CAUTION!

Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sani -
tizers 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.
CAUTION!
Do not use Alcohol and Alcohol-based and/
or Ketone based cleaning products to
clean leather upholstery, as damage to the
upholstery may result.

FUEL REQUIREMENTS —
GASOLINE ENGINE
2.0L Engine
This engine is designed to meet all emission
regulations, and provide satisfactory fuel
economy and performance when using
high-quality unleaded gasoline with a recom -
mended RON of 95.
While operating on gasoline with the
required octane number, hearing a light
knocking sound from the engine is not a
cause for concern. However, if the engine is
heard making a heavy knocking sound, see
your dealer immediately. Use of gasoline
with a lower than recommended octane
number can cause engine failure and may
void or not be covered by the New Vehicle
Limited Warranty.
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.
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.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 248

251
FUEL REQUIREMENTS —
DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier. If the outside temperature is very
low, the diesel fuel thickens due to the
formation of paraffin clots with consequent
defective operation of the fuel supply
system.
In order to avoid these problems different
types of fuel are distributed according to the
season: summer type, winter type and arctic
type (cold/mountain areas). If fueling with
diesel fuel whose features are not suitable
for the temperature of use, it is advisable to
mix in a suitable additive with the fuel. With
the proportions shown on the container, pour
the additive in the tank before fueling.
When using or parking the vehicle for a long
time in the mountains or cold areas, it is
advisable to refuel using locally available
fuel. In this case, it is also advisable to keep
the tank over half full.
This vehicle must only use premium diesel
fuel that meets the requirements of EN 590.
Biodiesel blends up to 7% that meet EN
590 may also be used.Diesel fuel is seldom completely free of
water. To prevent fuel system trouble, drain
the accumulated water from the fuel/water
separator using the provided fuel/water
separator drain. If you buy good quality fuel
and follow the cold weather advice above,
fuel conditioners should not be required in
your vehicle. If available in your area, a high
cetane “premium” diesel fuel may offer
improved cold-starting and warm-up perfor
-
mance.
Fuel Icon Identification Compliant To
EN16942
The following symbols make it easier to
recognize the correct type of fuel to be used
on your vehicle. Before proceeding with the
supply, check the symbols placed inside the
fuel filler flap (if present) and compare them
with the symbol on the fuel pump (if
present).
WARNING!
Do not use alcohol or gasoline as a
fuel-blending agent. They can be unstable
under certain conditions and hazardous or
explosive when mixed with diesel fuel.
CAUTION!
The manufacturer requires that you must
fuel this vehicle with Ultra Low Sulfur
Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low
Sulfur Highway Diesel fuel.

UCONNECT SYSTEMS
For detailed information about your Ucon-
nect system, refer to your Uconnect Owner’s
Manual Supplement.
NOTE:
Uconnect screen images are for illustration
purposes only and may not reflect exact soft -
ware for your vehicle.
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
systems and wireless communications.
Vehicle software technology continues to
evolve over time and FCA, working with its
suppliers, evaluates and takes appropriate
steps as needed. Similar to a computer or
other devices, your vehicle may require soft -
ware updates to improve the usability and performance of your systems or to reduce the
potential risk of unauthorized and unlawful
access 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.
NOTE:
FCA or your dealer may contact you
directly regarding software updates.
To help further improve vehicle security
and minimize the potential risk of a secu
-
rity breach, vehicle owners should:
Only connect and use trusted media devices (e.g. personal mobile phones,
USBs, CDs). WARNING!
It is not possible to know or to predict all
of the possible outcomes if your vehicle’s
systems are breached. It may be possible
that vehicle systems, including safety
related systems, could be impaired 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
may increase the possibility for vehicle
systems to be breached.

As always, if you experience unusual
vehicle behavior, take your vehicle to your
nearest authorized dealer immediately.
