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
rating information can be found on most
washer fluid containers.
Maintenance-Free Battery
Your vehicle is equipped with a mainte -
nance-free battery. You will never have to
add water, nor is periodic maintenance
required.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised
when filling or working around the washer
solution.
CAUTION!
Do not travel with the windshield washer
fluid reservoir empty: the windshield
washer is essential for improving visibility.
WARNING!
Using the battery with low fluid will
irreparably damage the battery and may
cause an explosion.
When performing any operation on the
battery or near it, always protect your
eyes with special goggles.
Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an autho-
rized dealership.
Battery fluid is a corrosive acid solution
and can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid
splashes in eyes or on skin, flush the
area immediately with large amounts of
water. Refer to “Jump Starting Proce-
dure” in “In Case Of Emergency” for
further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or
any other booster source with an output
greater than 12 Volts. Do not allow cable
clamps to touch each other.
Battery posts, terminals, and related
accessories contain lead and lead
compounds. Wash hands after handling.
CAUTION!
It is essential when replacing the cables
on the battery that the positive cable is
attached to the positive post and the
negative cable is attached to the nega-
tive post. Battery posts are marked posi -
tive (+) and negative (-) and are
identified on the battery case. Cable
clamps should be tight on the terminal
posts and free of corrosion.
If a “fast charger” is used while the
battery is in the vehicle, disconnect both
vehicle battery cables before connecting
the charger to the battery. Do not use a
“fast charger” to provide starting
voltage.

DEALER SERVICE
An authorized dealer has the qualified
service personnel, special tools, and equip-
ment to perform all service operations in an
expert manner. Service Manuals are avail -
able which include detailed service informa -
tion for your vehicle. Refer to these Service
Manuals before attempting any procedure
yourself. NOTE:
Intentional tampering with emissions control
systems may void your warranty and could
result in civil penalties being assessed
against you.
Air Conditioner Maintenance
For best possible performance, your air
conditioner should be checked and serviced
by an authorized dealer at the start of each
warm season. This service should include
cleaning of the condenser fins and a perfor
-
mance test. Drive belt tension should also be
checked at this time.
CAUTION!
Cleaning the engine compartment with a
high pressure washer is not recommended.
Precautions have been taken to safeguard
all parts and connections however, the
pressures generated by these machines is
such that complete protection against
water ingress cannot be guaranteed.
WARNING!
You can be badly injured working on or
around a motor vehicle. Only do service
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a
competent mechanic.
WARNING!
Use only refrigerants and compressor
lubricants approved by the manufacturer
for your air conditioning system. Some
unapproved refrigerants are flammable
and can explode, injuring you. Other
unapproved refrigerants or lubricants
can cause the system to fail, requiring
costly repairs. Refer to Warranty Infor -
mation Book, located in your owner’s
information kit, for further warranty
information.
The air conditioning system contains
refrigerant under high pressure. To avoid
risk of personal injury or damage to the
system, adding refrigerant or any repair
requiring lines to be disconnected
should be done by an experienced tech -
nician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.

See an authorized dealer for service.
Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield and rear window periodi-
cally with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove accu -
mulations of salt, waxes, or road film, and
help reduce streaking and smearing.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield or rear window.
Avoid using the wiper blades to remove frost
or ice from the windshield or rear window.
Make sure that they are not frozen to the
glass before turning them on to avoid
damaging the blade. Keep the wiper blade
out of contact with petroleum products such
as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies
depending on geographical area and
frequency of use. Poor performance of
blades may be present with chattering, marks, water lines or wet spots. If any of
these conditions are present, clean the wiper
blades or replace as necessary.
Exhaust System
The best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can
be detected inside the vehicle; or when the
underside or rear of the vehicle is damaged;
have an authorized technician inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, have the exhaust system inspected
each time the vehicle is raised for lubrication
or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventu
-
ally poison you. To avoid breathing CO,
refer to “Safety Tips” in “Safety” for
further information.
A hot exhaust system can start a fire if
you park over materials that can burn.
Such materials might be grass or leaves
coming into contact with your exhaust
system. Do not park or operate your
vehicle in areas where your exhaust
system can contact anything that can
burn.
CAUTION!
The catalytic converter requires the use
of unleaded fuel only. Leaded gasoline
will destroy the effectiveness of the cata-
lyst as an emissions control device and
may seriously reduce engine perfor -
mance and cause serious damage to the
engine.
2020_JEEP_M6_UG_UK.book Page 228

229(Continued)
Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst
operation and prevent possible catalyst
damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a
scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs,
stop the vehicle, turn off the engine and allow it to cool. Service, including a tune-up
to manufacturer's specifications, should be
obtained immediately.
To minimize the possibility of catalytic
converter damage:
Do not interrupt the ignition when the
transmission is in gear and the vehicle is
in motion.
Do not try to start the vehicle by pushing
or towing the vehicle.
Do not idle the engine with any ignition
components disconnected or removed,
such as when diagnostic testing, or for
prolonged periods during very rough idle or
malfunctioning operating conditions.
Cooling System
Coolant Checks
Check engine coolant (antifreeze) protec
-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty or rusty
in appearance, the system should be
drained, flushed and refilled with fresh
engine coolant (antifreeze). Check the front
of the A/C condenser for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the condenser.
Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of
engine malfunction, particularly
involving engine misfire or other
apparent loss of performance, have your
vehicle serviced promptly. Continued
operation of your vehicle with a severe
malfunction could cause the converter to
overheat, resulting in possible damage to
the converter and vehicle.
CAUTION! (Continued)
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.

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
in sets of four; failure to do so may adversely
affect the safety and handling of your
vehicle.
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.
Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at
sustained 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
NOTE:
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.
Refer to the “Towing Requirements - Tires”
in “Starting And Operating” in the Owner’s
Manual for restrictions when towing with a
spare tire designated for temporary emer -
gency use.
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 -
WARNING!
Do not use Summer tires in snow/ice
conditions. 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.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an
automatic car wash with a compact or
limited use temporary spare installed.
Damage to the vehicle may result.

Preserving The Bodywork
Washing
Wash your vehicle regularly. Always wash
your vehicle in the shade using a mild car
wash soap, and rinse the panels
completely with clear water.
If insects, tar, or other similar deposits
have accumulated on your vehicle, use a
specific detergent to remove.
Use a high quality cleaner wax to remove
road film, stains and to protect your paint
finish. Take care never to scratch the
paint.
Avoid using abrasive compounds and
power buffing that may diminish the gloss
or thin out the paint finish.
Special Care
If you drive on salted or dusty roads or if
you drive near the ocean, hose off the
undercarriage at least once a month.
It is important that the drain holes in the
lower edges of the doors, rocker panels,
and trunk be kept clear and open.
If you detect any stone chips or scratches
in the paint, touch them up immediately.
The cost of such repairs is considered the
responsibility of the owner.
If your vehicle is damaged due to a colli-
sion or similar cause that destroys the
paint and protective coating, have your
vehicle repaired as soon as possible. The
cost of such repairs is considered the
responsibility of the owner.
If you carry special cargo such as chemi -
cals, fertilizers, de-icer salt, etc., be sure
that such materials are well packaged and
sealed.
If a lot of driving is done on gravel roads,
consider mud or stone shields behind
each wheel.
Touch up the scratches as soon as
possible. An authorized dealer has touch
up paint to match the color of your vehicle.
Some parts of the vehicle may be painted
with a matte paintwork which requires
special care for its preservation

FUEL REQUIREMENTS —
GASOLINE ENGINE
1.4L Turbo Gasoline Engine
This engine is designed to meet all emission
regulations and provide satisfactory fuel
economy and performance when using
high-quality unleaded gasoline having a
minimum research octane rating (RON) of
95. For optimum performance and fuel
economy the use of minimum research
octane rating (RON) of 98 or higher is recom-
mended. 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.
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
vehicle be operated on fuel containing no
more than 10% ethanol. Purchasing your
fuel from a reputable supplier may reduce
the risk of exceeding this 10% limit and/or of
receiving fuel with abnormal properties.
Materials Added To Fuel
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish
removal may contain active solvents or
similar ingredients. These can harm fuel
system gasket and diaphragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol.
CAUTION!
Do not load your vehicle any heavier than
the GVWR or the maximum front and rear
GAWR. If you do, parts on your vehicle can
break, or it can change the way your
vehicle handles. This could cause you to
lose control. Also overloading can shorten
the life of your vehicle. Never exceed the
maximum combined vehicle load value:
the maximum towable load is only allowed
if it does not exceed the maximum
combined vehicle load.
CAUTION!
Use of fuel with Ethanol content higher
than 10% may result in engine
malfunction, starting and operating
difficulties, and materials degradation.
These adverse effects could result in
permanent damage to your vehicle.
CAUTION!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more
than 15% ethanol (E-15). Use of these
blends may result in starting and
drivability problems, damage critical fuel
system components, cause emissions to
exceed the applicable standard, and/or
cause the Malfunction Indicator Light to
illuminate. Please observe pump labels as
they should clearly communicate if a fuel
contains greater than 15% ethanol (E-15).

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.
