A - fan knob and climate control system
compressor button.
B - recirculation control / air intake from
outside knob.
C - air distribution knob:
air flow to central and side
dashboard vents to ventilate the
chest and the face in warm
weather;
distribution between feet area
diffusers (warmest air) and
dashboard diffusers (coolest air);
towards the footwell diffusers. Due
to the natural tendency of heat to
spread upwards, this type of
distribution warms the passenger
compartment up as quickly as
possible, providing an immediate
feeling of warmth;
distribution between footwell
diffusers and windscreen/front
side window vents. This type of
distribution achieves effective
heating of the passenger
compartment and prevents the
windows from misting up;
air flow to the windscreen and
front side window diffusers to
demist or defrost them.
D - heated rear windscreen button.
E - temperature adjustment knob.Press the knob A fig. 26 to turn the
climate control system on and off.
NOTE Optimal cooling/heating of the
passenger compartment may not
be guaranteed together with

of the climate control system,
deactivate the Start&Stop function.
NOTE To stop the air flow from the
vents, turn the knob to 0.
IMPORTANT It is advisable to switch
the air recirculation on whilst queueing
or in tunnels to prevent the introduction
of polluted air. However, it is better
not to use the function for long periods,
particularly if there are many people
on board, to prevent the windows from
misting.
AIR RECIRCULATION
(knob B fig. 26)
internal air recirculation
air intake from outside
Use air recirculation for maximum
climate control performance.
To demist the windows, set the
recirculation control to on
.

LED on button OFF = recirculation OFF.
IMPORTANT It is inadvisable to use
air recirculation when the outside
temperature is low, since the windows
could mist rapidly.
I - Automatic climate control
system on/offWARNING
2)The system uses R1234yf coolant,
which is compatible with the laws in force
in the countries where the vehicle is sold.
When charging, only use the gas indicated
on the dedicated plate in the engine
compartment . The use of other coolants
affects the efficiency and condition of
the system. The lubricant used for the
compressor is also strictly linked to the
type of cooling gas, please refer to a Fiat
Dealership.

KNOWING YOUR CAR

ENGINE OIL
Check the oil level a few minutes (about
5) after the engine has stopped, with
the vehicle parked on level ground.
NOTE The dipstick is integrated in the
engine oil cap on 0.9 TwinAir 85 HP
versions.
For 1.2 8V versions:pull out the
engine oil dipstick B, clean it with a
cloth that does not leave any trace and
reinsert it..
For 0.9 TwinAir 85 HP version:The
engine oil dipstick A is integral with plug
A. Loosen the plug, clean the dipstick
with a cloth that does not leave traces,
reinsert the dipstick and re-tighten
the plug.
Extract the engine oil dipstick again and
check that the level is between the
MIN and MAX marks on the dipstick.
If the oil level is near or under the MIN
line, add oil through the filler A until
it reaches the MAX line.
The range between the MIN. and MAX.
marks corresponds to about 1 litre of
oil.
The oil level must never exceed the
MAX mark.
Engine oil consumption
The maximum engine oil consumption
is usually 400 grams every 1000 km.When the car is new, the engine needs
to be run in; therefore the engine oil
consumption can only be considered
stabilised after the first 5000 - 6000
km.
IMPORTANT The oil consumption
depends on driving style and the
conditions under which the car is used.
IMPORTANT After adding or changing
the oil, let the engine turn over for a few
seconds and wait a few minutes after
turning it off before you check the level.

ENGINE COOLING
SYSTEM FLUID
The coolant level must be checked
when the engine is cold and must
range between the MIN and MAX
marks on the reservoir.
If the level is too low, undo the reservoir
plug C (see previous pages) and add
the fluid as described in the chapter
"Technical Specifications".
176)
62)
WINDSCREEN/REAR
WINDOW WASHER FLUID
Check fluid level through the reservoir.
If the level is too low, lift the plug D (see
previous pages) and add the fluid as
described in the chapter "Technical
Specifications".
After topping up, close cap D, making
sure it is correctly locked.
177)
BRAKE FLUID
Check that the fluid is at the maximum
level (the fluid level in the reservoir
must not exceed the MAX mark).
If the fluid level in the tank is too low,
undo reservoir cap E (see previous
pages) and add the fluid as described
in the "Technical Specifications"
section.
NOTE Carefully clean the plug of the
reservoir E and the surrounding surface.
Take great care to ensure that
impurities do not enter the reservoir
when the cap is opened.
Always use a funnel with a built-in filter
with a mesh of 0.12 mm or less.
147

IMPORTANT Brake fluid is hygroscopic
(i.e. it absorbs moisture). For this
reason, if the car is mainly used in areas
with a high degree of atmospheric
humidity, the fluid must be replaced at
more frequent intervals than specified in
the "Scheduled Servicing Plan".

4)
The fluid level should only be checked
at a Fiat Dealership.
WARNING
174)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of
fire.
175)Be very careful when working in the
engine compartment when the engine
is hot: you may get burned. Remember
that the fan may start up if the engine
is hot: this could injure you. Scarves, ties
and other loose clothing might be pulled by
moving parts.176)The cooling system is pressurised. If
necessary, only replace the plug with
another original or the operation of the
system may be adversely affected. Do not
remove the reservoir plug when the engine
is hot: you risk scalding yourself.
177)Do not travel with the windscreen
washer fluid reservoir empty: the
windscreen washer is essential for
improving visibility. Some commercial
windscreen washer additives are
flammable. The engine compartment
contains hot components which may set it
on fire.
178)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.
179)The
symbol on the reservoir
identifies synthetic brake fluids,
distinguishing them from the mineral type.
Use of mineral type fluids will damage
the special rubber seals of the braking
system beyond repair.
WARNING
59)When topping up, take care not to mix
up the various types of fluids: they are
not compatible with each other and could
seriously damage the car.
60)The use of products with specifications
other than those indicated above could
cause damage to the engine not covered
by the warranty.61)Do not add oil with specifications other
than those of the oil already existing in
the engine.
62)PARAFLU
UPanti-freeze is used in the
engine cooling system. Use the same fluid
as in the cooling system when topping
up. PARAFLU
UPcannot be mixed with any
other type of fluid. If this occurs, do not
start the engine and contact your Fiat
Dealership immediately.
63)Prevent brake fluid, which is highly
corrosive, from coming into contact with
painted parts. Should it happen,
immediately wash with water.
WARNING
3)Used engine oil and oil filters contain
substances which are harmful to the
environment. To change the oil and filters,
we advise you to contact a Fiat Dealership.
4)Used transmission fluid contains
substances that are harmful to the
environment. It is advisable to have the oil
changed by a Fiat Dealership where it
will be disposed of respecting the
environment and according to legal
requirements.
