Adequate care of your vehicle at regular
intervals serves to preserve the value
and appearance as long as possible.
Maintenance items as described in this
owner’s manual can be performed by
the owner.
We recommend you to have the
periodic inspection and maintenance
performed by a Fiat Dealership.
In the event a malfunction or a problem
is discovered, we recommend you to
have it checked and repaired. This
section contains information on
inspection maintenance procedures
that you can do yourself. Follow the
instructions and cautions for each of
the various procedures.
IMPORTANT NOTE!
The customer can have servicing done
outside the authorised Fiat Dealership
without losing the warranty in force. The
warranty depends on carrying out the
scheduled servicing constantly, as
described in this Owner Handbook.
The customer can choose to have the
above mentioned servicing, and any
other repairs covered by the warranty,
carried out by any workshop (within or
outside the Fiat Dealership), as long as
it has suitable means and follows the
instructions described in this Owner
Handbook.
WARNING
362)When checking or servicing the inside
of the engine compartment, make sure the
engine is switched off and has had a
chance to cool down.
363)If it is necessary to do work in the
engine compartment with the engine
running, be especially careful that your
clothing, hair, etc., does not become
caught by the cooling fan, drive belts, or
other moving parts.
364)After performing the maintenance
work, make sure that no tools or cloths are
left behind in the engine compartment. If
they are left behind, a fire or damage to the
vehicle may occur.
365)The cooling fan can turn on
automatically even if the engine is not
running. Turn the ignition switch to “LOCK”
position or put the operation mode in OFF
to be safe while you work in the engine
compartment.
366)Do not smoke, cause sparks or allow
open flames around fuel or battery. The

CATALYTIC
CONVERTER
372)
The exhaust gas scavenging devices
used with catalytic converter are
extremely efficient for the reduction of
noxious gases. The catalytic converter
is installed in the exhaust system.
It is important to keep the engine
properly tuned to ensure proper catalyst
operation and prevent possible catalyst
damage.
NOTE Use fuel of the type
recommended in “Fuel selection”.
WARNING
372)As with any vehicle, do not park or
operate this vehicle in areas where
combustible materials such as dry grass or
leaves can come in contact with a hot
exhaust since a fire could occur.
ENGINE OIL
To check and refill engine oil
373)
A — Minimum level
B — Maximum level
C — Oil replacement indication mark
The engine oil used has a significant
effect on the engine’s performance,
service life and startability. Be sure to
use oil of the recommended quality and
appropriate viscosity. All engines
consume a certain amount of oil during
normal operation. Therefore, it is
important to check the oil level at
regular intervals or before starting a
long trip.
1. Park the car on a horizontal surface.
2. Switch off the engine.
3.Wait a few minutes.
4. Remove the dipstick and wipe it with
a clean cloth.5. Reinsert the dipstick as far as it
goes.
6. Remove the dipstick and read the oil
level, which should always be within the
range indicated.
7. If the oil level is below the specified
limit, remove the cap located on the
cylinder head cover and add enough oil
to raise the level to within the specified
range. Do not overfill to avoid engine
damage. Be sure to use the specified
engine oil and do not mix various types
of oil.
8. After adding oil, close the cap
securely.
9. Confirm the oil level by repeating
step 4 to 6.
NOTE Check or refill the oil according
to the following manner.
When the oil level is checked in step
6 above, check it on a low side of the
dipstick because it is different in
appearance of oil level in the two sides
of the dipstick.
On vehicles without diesel particulate
filter (DPF), the oil level should be within
the range (A) to (B) on the dipstick.
On vehicles with DPF, the oil level
should be within the range (A) to (C) (oil
replacement indication mark) on the
dipstick. If the oil level is beyond the oil
replacement indication mark (C),
replace the oil as soon as possible.
Then, the oil should be refilled to the
459AHA102654
256
SERVICING AND MAINTENANCE
maximum level (B).

On vehicle with DPF, the engine oil
will be increased due to a few of the
fuel gets mixed in the engine oil when
the DPF regenerates to burn away the
PM (particulate matter). However, it
does not indicate a malfunction.
The engine oil level will be increased
due to an amount of the fuel being
mixed in the engine oil when the DPF
regenerates to burn away the PM
(particulate matter). It does not indicate
a malfunction. In the following
conditions, the engine oil level may
increase easily. We recommend you to
have it checked frequently.:
frequent driving at uphill and
downhill;
frequent driving at high altitudes;
frequent and extended idling;
frequent driving through a traffic jam.
NOTE The engine oil will deteriorate
rapidly if the vehicle is subjected to
severe conditions, requiring earlier oil
replacement. Please refer to the
maintenance schedule.
Selection of engine oil
Refer to “Refill Capacities” under
Technical Specifications.Safety and disposal information for
used engine oil
374) 375) 376)
Protect the environment
It is illegal to pollute drains, water
courses and soil. Use authorized waste
collection facilities, including civic
amenity sites and garages providing
facilities for disposal of used oil and
used oil filters. If in doubt, contact your
local authority for advice on disposal.
WARNING
373)If the engine oil is being topped up,
wait for the engine to cool down before
loosening the filler cap, particularly for
vehicles with aluminium cap (where
provided). WARNING: risk of burns!
374)Prolonged and repeated contact may
cause serious skin diorders, including
dermatitis and cancer.
375)Avoid contact with the skin as far as
possible and wash thoroughly after any
contact.
376)Keep use engine olis out of reach of
children.
ENGINE COOLANT
To check the coolant level
A transparent coolant reserve tank (A) is
located in the engine compartment. The
coolant level in this tank should be kept
between the “L” (LOW) and “F” (FULL)
marks when measured while the engine
is cold.
460AHM100742
257

To add coolant
The cooling system is a closed system
and normally the loss of coolant should
be very slight. A noticeable drop in the
coolant level could indicate leakage. If
this occurs, we recommend you to
have the system checked as soon as
possible. If the level should drop below
the “L” (LOW) level on the reserve tank,
open the lid and add coolant.
Also, if the reserve tank is completely
empty, remove the radiator cap (B) and
add coolant until the level reaches the
filler neck.
377) 378)
Anti-freeze
The engine coolant contains an
ethylene glycol anti-corrosion agent.
Some parts of the engine are cast
aluminium alloy, and periodic changing
of the engine coolant is necessary to
prevent corrosion of these parts.
Use the recommended coolant by Fiat
or equivalent (similar high quality
ethylene glycol based non-silicate,
non-amine, nonnitrate and nonborate
coolant with long life hybrid organic
acid technology).
Fiat genuine coolant has excellent
protection against corrosion and rust
formation of all metals including
aluminium and can avoid blockages in
the radiator, heater, cylinder head,
engine block, etc.Because of the necessity of this
anti-corrosion agent, the coolant must
not be replaced with plain water even in
summer. The required concentration of
anti-freeze differs depending on the
expected ambient temperature.
Above -35 °C: 50 % concentration of
antifreeze
Below -35 °C: 60 % concentration of
antifreeze
183) 184) 185) 186) 187)
During cold weather
If the temperatures in your area drop
below freezing, there is the danger that
the coolant in the engine or radiator
could freeze and cause severe damage
to the engine and/or radiator. Add a
sufficient amount of antifreeze to the
coolant to prevent it from freezing.
The concentration should be checked
before the start of cold weather and
anti-freeze added to the system if
necessary.
WARNING
377)The used engine oil and the filter that
has been replaced contain substances that
are harmful to the environment. To change
the oil and filters, we advise you to contact
a Fiat Dealership.
378)Do not open the radiator cap (B) while
the engine is hot. The coolant system is
under pressure and any hot coolant
escaping could cause severe burns.
IMPORTANT
183)Do not use alcohol or methanol
anti-freeze or any engine coolants mixed
with alcohol or methanol anti-freeze. The
use of an improper anti-freeze can cause
corrosion of the aluminium components.
184)Concentrations exceeding 60 % will
result in a reduction of both the anti-freeze
and cooling performance thus adversely
affecting the engine.
185)Do not top up with water only.
186)PARAFLU UP anti-freeze is used in
the engine cooling system. Use fluid of the
same type as that contained in the cooling
system for any top-ups. PARAFLU UP
cannot be mixed with any other type of
fluid. If this happens, do not start the
engine under any circumstances and
contact a Fiat Dealership.
187)Do not use water to adjust the
concentration of coolant.
