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.

Loading
The vehicle maximum load on the tire must
not exceed the load carrying capacity of the
tire on your vehicle. You will not exceed the
tire's load carrying capacity if you adhere to
the loading conditions, tire size, and cold tire
inflation pressures specified on the Tire
Information placard.
NOTE:
Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the
front and rear axles must not be exceeded.
Radial Ply 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 than a ¼ of an
inch (6 mm). Consult an authorized tire dealer for tire
repairs 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).
Replace the tire pressure sensor as well as it
is not designed to be reused.
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 the run flat
mode it has limited driving capabilities and
needs to be replaced immediately. A Run Flat
tire is not repairable. When a run flat tire is
changed after driving with underinflated tire
condition, please replace the TPM sensor as it
is not designed to be reused when driven
under run flat mode (14 psi (96 kPa)) condi -
tion.

NOTE:
TPM Sensor must be replaced after driving
the vehicle on a flat tire condition.
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).
WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your
stopping distance. Use tires of the
recommended load capacity for your
vehicle. Never overload them.
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.
2020_JEEP_M6_UG_UK.book Page 234

235
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
conditions, 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” for further information.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.Tire Tread
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a 1/16
of an inch (1.6 mm). When the tread is worn
to the tread wear indicators, the tire should
be replaced.
Refer to “Replacement Tires” in this section
for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These
abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire
replacement.
Distance driven.
Performance tires, tires with a speed
rating of V or higher, and Summer tires
typically have a reduced tread life. Rota-
tion of these tires per the vehicle sched -
uled maintenance is highly recommended.
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 30 mph (48 km/h) for more than
30 seconds continuously when you are
stuck, and do not let anyone near a
spinning wheel, no matter what the
speed.1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.

(Continued)
NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and
tear in existing tires.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a
balance of many characteristics. They should
be inspected regularly for wear and correct
cold tire inflation pressures. The manufac-
turer strongly recommends that you use tires
equivalent to the originals in size, quality
and performance when replacement is
needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the
Tire and Loading Information placard or the
Vehicle Certification Label for the size desig -
nation of your tire. The Load Index and
Speed Symbol for your tire will be found on
the original equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels. It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifica
-
tions or capability. Failure to use equivalent
replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identi -
fied by the M+S, M&S, M/S or MS designa -
tion 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.
WARNING!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision 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 result
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
speedometer and odometer readings.

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
vehicle 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 the sidewall of the tire. Compact spare
tire descriptions 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 orig -
inal 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.
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 vehicle
handling. 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!
Compact and collapsible spares are for
temporary emergency use only. With these
spares, do not drive more than 50 mph
(80 km/h). Temporary use spares have
limited 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.
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.

Tire Chains (Traction Devices)
Use of traction devices require sufficient
tire-to-body clearance. Follow these recom-
mendations to guard against damage:
Traction device must be of proper size for
the tire, as recommended by the traction
device manufacturer.
Install on front tires only.
For a 215/65R16 tire, use of a snow trac-
tion device with a maximum projection of
7 mm beyond the tire profile is recom -
mended.
No other tire sizes are recommended for
use with a tire chain or traction device.
NOTE:
Any aftermarket tire add on like tire chains
may effect the Tire Pressure Monitoring
System (TPMS) feature performance.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform
different steering, handling, and braking
functions. For these reasons, they wear at
unequal rates.
These effects can be reduced by timely rota -
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off Road type
tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels,
and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
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
suspension components, it is important
that only traction devices in good condi -
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately if noise occurs that could indi -
cate device breakage. Remove the
damaged parts of the device before
further use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
Do not drive for a prolonged period on
dry pavement.

Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer’s if it is less
than 30 mph (48 km/h).

Do not use traction devices on a compact
spare tire.

STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
Park your vehicle in a covered, dry and
possibly airy location the windows open
slightly.
Check that the Electric Park Brake is not
engaged.
Disconnect the negative (-) terminal from
the battery post and be sure that the
battery is fully charged. During storage
check battery charge quarterly.
If you do not disconnect the battery from
the electrical system, check the battery
charge every 30 days.
Clean and protect the painted parts by
applying protective waxes.
Clean and protect polished metal parts by
applying protective waxes.
Apply talcum powder to the front and rear
wiper blades and leave raised from the
glass.
Cover the vehicle with an appropriate
cover taking care not to damage the
painted surface by dragging across dirty
surfaces. Do not use plastic sheeting
which will not allow the evaporation of
moisture present on the surface of the
vehicle.
Inflate the tires at a pressure of +7.25 psi
(+0.5 bar) higher than recommended on
the tire placard and check it periodically.
Do not drain the engine cooling system.
Whenever you leave the vehicle stationary
for two weeks or more, idle the engine for
approximately five minutes, with the air
conditioning system on and high fan
speed. This will ensure proper lubrication
of the system, thus minimizing the possi -
bility of damage to the compressor when
the vehicle is put back into operation.
CAUTION!
Proper operation of four-wheel drive
vehicles depends on tires of equal size,
type and circumference on each wheel.
Any difference in tire size can cause
damage to the power transfer unit. Tire
rotation schedule should be followed to
balance tire wear.

Stain Repel Fabric Cleaning Procedure — If
Equipped
Stain Repel seats may be cleaned in the
following manner:
Remove as much of the stain as possible
by blotting with a clean, dry towel.
Blot any remaining stain with a clean,
damp towel.
For tough stains, apply a mild soap solu -
tion to a clean, damp cloth and remove
stain. Use a fresh, damp towel to remove
soap residue.

For grease stains, apply a specific product to
a clean, damp cloth and remove stain. Use a
fresh, damp towel to remove soap residue.
Do not use any harsh solvents or any other
form of protectants on Stain Repel products.

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.
CAUTION!
Avoid washing with rollers and/or brushes
in washing stations. Wash the vehicle only
by hand using neutral pH detergents; dry it
with a wet chamois leather. Abrasive
products and/or polishes should not be
used for cleaning the car. Bird droppings
must be washed off 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
outside temperature conditions.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable,
and if used in closed areas they may cause
respiratory harm.
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.).

preventing the vehicle from resting on the
ground with the body or chassis after
touching the wedge with its lowest and most
projecting parts (usually the underbody),

The wheels, without a suitable grip to the
ground, will not have sufficient hold to move
the vehicle, and will surge.
The higher the ground clearance, the wider
the breakover angle. Always bear in mind
that the higher the ground clearance, the
