ENGINE OIL
Check that the oil level is between the
MIN and MAX references on the
dipstick A. If the oil level is near or even
under the MIN line, add oil using the
filler B to reach the MAX line.
166)59)
Take out the engine oil dipstick A, clean
it with a lint-free cloth and reinsert it.
Extract it again and check that the level
is between the MIN and MAX marks
on the dipstick.
Engine oil consumption
60)4)
The maximum engine oil consumption
is usually 400 grams every 1,000 km.
During the initial period of use the
engine oil consumption conditions
should be considered as having
stabilised after the first 5000 - 6000
km.
ENGINE COOLANT
If the level is too low, unscrew the cap
of reservoir C and add the fluid
described in the "Technical
Specifications" section.
167)61)
WINDSCREEN/REAR
WINDOW WASHER FLUID
If the level is too low, lift reservoir cap D
and add the fluid described in the
chapter "Technical Specifications".
168) 169)
IMPORTANT The headlight washer
system will not operate when the fluid
level is low, even though the
windscreen/rear window washer
continues to operate. On some
versions there is a reference notch on
the dipstick: ONLY the windscreen/rear
window washer operates with the
level below this reference.
BRAKE FLUID
Check that the fluid is at the max. level.
If the fluid level in the reservoir is too
low, undo reservoir cap E and add the
fluid described in the chapter "Technical
Specifications".

BATTERY
172) 173) 174) 175)6)
The battery does not require the
electrolyte to be topped up with distilled
water. A periodic check carried out at
a Jeep Dealership is, however,
necessary to check efficiency.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel switches on to
indicate this. To carry out this
procedure turn the steering wheel all
the way from one end to the other
or drive in a straight line for about a
hundred metres.
IMPORTANT If the charge level remains
under 50% for a long time, the battery
is damaged by sulphation, reducing
its capacity and efficiency at start-up.
CLIMATE CONTROL
SYSTEM MAINTENANCE
In winter, the climate control system
must be turned on at least once a
month for about 10 minutes. Have the
system inspected at a Jeep Dealership
before the summer.

SERVICING AND MAINTENANCE

WARNING
164)Never smoke when performing
operations in the engine compartment.
Flammable gases and fumes may be
present and risk igniting.
165)Be very careful when working in the
engine compartment when the engine
is hot: you may get burned.
166)If the engine oil is being topped up,
wait for the engine to cool down before
loosening the filler plug, particularly for
vehicles with aluminium plug (where
provided). CAUTION: risk of burns!
167)The cooling system is pressurised. If
necessary, only replace the cap with
another original one or the operation of the
system may be adversely affected. Do
not remove the reservoir cap when the
engine is hot: risk of burns.
168)Do not travel with the windscreen
washer reservoir empty: the windscreen
washer is essential for improving visibility.
Repeated operation of the system without
fluid could damage or cause rapid
deterioration of some system components.
169)Certain commercial additives for
windscreen washer fluids are inflammable.
The engine compartment contains hot
components which may set it on fire.
170)Brake fluid is poisonous and highly
corrosive. In the event of accidental
contact, immediately wash the affected
parts with water and mild soap. Then rinse
thoroughly. Call a doctor immediately if
swallowed.171)The
symbol on the container
indicates a synthetic brake fluid, which is
different from a mineral fluid. Using a
mineral fluid will damage the special rubber
seals of the braking system beyond repair.
172)Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.
173)Using the battery with insufficient
fluid irreparably damages the battery and
may cause an explosion.
174)If the vehicle must remain unused for
a long time at a very low temperature,
remove the battery and take it to a warm
place, to avoid freezing.
175)When performing any operation on
the battery or near it, always protect your
eyes with special goggles.
WARNING
58)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
severely damage your vehicle.
59)The oil level should never exceed the
MAX mark.
60)Do not add oil with specifications other
than those of the oil already in the engine.61)PARAFLU
UPanti-freeze fluid is used in
the engine cooling system; use the same
fluid type as that already in the cooling
system when topping up. PARAFLU
UP
may not be mixed with other types of
anti-freeze fluids. In the event of topping up
with an unsuitable product, under no
circumstances start the engine and contact
a Jeep Dealership.
62)Avoid allowing brake fluid, which is
extremely corrosive, to come into contact
with painted areas. Should it happen, wash
immediately with water.
63)Incorrect assembly of electrical and
electronic accessories may cause severe
damage to your vehicle. Go to a Jeep
Dealership if you want to install accessories
(e.g. anti-theft, radio phone, etc.): they will
suggest the most suitable devices and
advise you whether a higher capacity
battery needs to be installed.
WARNING
4)Used engine oil and oil filters contain
substances which are harmful to the
environment. You are advised to contact a
Jeep Dealership to have the oil and filters
changed.
5)Used transmission fluid contains
substances that are harmful to the
environment. It is advisable to contact a
Jeep Dealership for oil changes.
6)Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact a Jeep
Dealership.

IMPORTANT In versions with a sun
roof, make sure that the sun roof is
closed before operating the window
washer jets.
Rear window washer
The rear window washer jets are fixed.
The nozzle holder is located above
the rear window.
WARNING
176)The air intake system (air cleaner,
rubber hoses, etc.) can be a protection in
the case of blowbacks from the engine.
DO NOT REMOVE this system unless you
need to carry out repair or servicing
operations. Before starting the engine
make sure the system is not dismantled:
failure to comply with this precaution
may cause serious injuries.
177)Exhaust emissions are very
dangerous and may be fatal. They contain
carbon monoxide, a colourless and
odourless gas which, if inhaled, may cause
fainting and poisoning.
178)The exhaust system can reach high
temperatures and cause a fire if the vehicle
is parked on flammable material. Dry grass
or leaves can also catch fire if they come
into contact with the exhaust system.
Do not park or use the vehicle in a place in
which the exhaust system might come
into contact with flammable material.
WARNING
64)Incorrect maintenance of the vehicle or
failure to carry out operations or repairs
(when necessary) may lead to more
expensive repairs, damage to other
components or a negative impact on the
vehicle performance. Have any operating
faults immediately checked by a Jeep
Dealership.
65)The vehicle is equipped with fluids
optimised for protecting its performance
and duration, and to extend servicing
intervals. Do not use chemicals for washing
these components since they may
damage the engine, the gearbox or the
climate control system. This damage is not
covered by the vehicle’s warranty. If, due
to malfunction of a component, washing is
needed, only use the fluid specific for
that procedure.
66)An excessive or insufficient amount of
oil in the block is extremely harmful for
the engine. Make sure it is always at an
adequate level.
67)Always require the use of only
compressor coolants and lubricants
approved and suitable for the specific air
conditioning system fitted on the vehicle.
Some non-approved coolants are
flammable and may explode, with the risk
of injuries. The use of non-approved
coolants or lubricants may adversely affect
system efficiency, leading to expensive
repairs.68)The air conditioning system contains
high-pressure coolant: to prevent damage
to people or the system, any topping-up
with fuel or repairs that involves
disconnection of the pipes must be carried
out by a Jeep Dealership.
69)Vehicles equipped with a catalytic
converter must be exclusively supplied with
unleaded petrol. Leaded petrol would
permanently damage the catalytic
converter and eliminate its ability to reduce
polluting emissions, seriously
compromising the engine performance,
which would be irreparably damaged. If the
engine does not work correctly, especially
if it starts irregularly or if there is a reduction
of its performance, immediately go to a
Jeep Dealership. Prolonged and faulty
operation of the engine may cause
overheating of the converter and, as a
consequence, possible damage to the
converter and the vehicle.
70)Using a gearbox fluid different from that
approved may compromise gearshifting
quality and/or cause vibration of the
gearbox itself.
71)It is recommended to have the vehicle
serviced by a Jeep Dealership. When
carrying out normal periodic operations
and small servicing interventions personally
on the vehicle, it is recommended to use
suitable equipment, original spare parts
and the necessary fluids. Do not carry out
any interventions if you don't have the
necessary experience.
