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.

Cooling System Pressure Cap
The cap must be fully tightened to prevent
loss of engine coolant (antifreeze), and to
ensure that engine coolant (antifreeze) will
return to the radiator from the coolant expan-
sion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if
there is any accumulation of foreign material
on the sealing surfaces.
Brake System
In order to assure brake system performance,
all brake system components should be
inspected periodically. Refer to the “Mainte -nance Plan” in this section for the proper
maintenance intervals.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood
services or immediately if the “Brake
Warning Light” is illuminated.
Be sure to clean the top of the master
cylinder area before removing the cap. If
necessary, add fluid to bring the fluid level
up to the requirements described on the
brake fluid reservoir. With disc brakes, fluid
level can be expected to fall as the brake
pads wear. Brake fluid level should be
checked when pads are replaced. However,
low fluid level may be caused by a leak and
a checkup may be needed.
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubricants”
in “Technical Specifications” for further
information.
WARNING!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze)
when the engine is overheated. Do not
loosen or remove the cap to cool an over
-
heated engine. Heat causes pressure to
build up in the cooling system. To
prevent scalding or injury, do not remove
the pressure cap while the system is hot
or under pressure.
Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake
temperatures, excessive lining wear, and
possible brake damage. You would not
have your full braking capacity in an
emergency. WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its
performance. The proper type of brake
fluid for your vehicle is also identified on
the original factory installed hydraulic
master cylinder reservoir.
To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master
cylinder reservoir cap secured at all
times. Brake fluid in a open container
absorbs moisture from the air resulting
in a lower boiling point. This may cause
it to boil unexpectedly during hard or
prolonged braking, resulting in sudden
brake failure. This could result in a colli -
sion.

RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort And Vehicle StabilitySafety
Both underinflation and overinflation affect
the stability of the vehicle and can produce
a feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
Unequal tire pressures from side to side
may cause erratic and unpredictable
steering response.
Unequal tire pressure from side to side
may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump -
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort -
able ride. Overinflation produces a jarring
and uncomfortable ride.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately. WARNING!
Improperly inflated tires are dangerous
and can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that
result in tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle
control.
Unequal tire pressures can cause
steering problems. You could lose
control of your vehicle.
Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pres-
sure.
