INDEPENDENT
ADDITIONAL
HEATER(for versions/markets, where provided)
The vehicle is available, on request,
with two different independent heaters:
one fully automatic, the other which
can be programmed.
AUTOMATIC VERSION
The additional heater is turned on in
automatic mode when the engine
is started and the required outside
temperature and coolant conditions are
present. Deactivation is always
automatic.
21)
IMPORTANT During periods with low
outdoor temperatures when the device
cuts in, check that the fuel level is
always higher than the reserve level.
Otherwise the device could lock and
require the assistance of a Fiat
Dealership.
PROGRAMMABLE
VERSION
The additional heater operates
completely independently of engine
operation and allows the following:❒heating the passenger compartment
with the engine off
❒defrosting the windows;
❒heat the engine coolant and then the
engine itself prior to starting.
The system consists of:
❒a diesel burner for heating the water
with an exhaust silencer for the
combustion gases;
❒a metering pump connected to the
reservoir pipes for supplying the
burner;
❒a heat exchanger connected to the
engine cooling system pipes;
❒a control unit connected to the
passenger compartment
heating/ventilation system to allow
automatic operation;
❒an electronic control unit for
controlling and adjusting the built-in
burner;
❒a digital timer fig. 54 for turning the
heater on manually or for
programming the time that it comes
on.The additional heater (during winter)
heats, maintains the temperature of and
circulates engine coolant for a set time
period in order to ensure optimum
engine and passenger compartment
conditions at engine start-up.
The heater can operate automatically
when programmed with a digital timer
or manually by pressing the 'immediate
heating' button on the timer.
After heater activation, whether
programmed or manually, the electronic
control unit operates the coolant pump
and turns on the burner in accordance
with pre-set, controlled procedures.
The circulation pump output is also
controlled by the electronic control unit
in order to minimise the initial heating
time.
When the system operates, the control
unit turns on the passenger
compartment heater unit fan at the
second speed.
The thermal power of the boiler is
regulated automatically by the
electronic control unit depending on the
temperature of the engine coolant.

Warning lights on
displayWhat it means What to do
ENGINE COOLANT TEMPERATURE
TOO HIGH
When the key is turned to MAR-ON, the
warning light switches on but should switch
off after a few seconds. The warning light
turns on when the engine is overheated.
The display shows the dedicated message.When driving normally: stop the vehicle, switch off the
engine and check that the water level in the reservoir is
not below the MIN mark. If it is, wait for the engine to
cool down then slowly and carefully open the cap, top
up with coolant and check that the level is between the
MIN and MAX marks on the reservoir. Also check
visually for any fluid leaks. If, when restarting, the
warning light switches on again, contact a Fiat
Dealership.
If the vehicle is used under demanding conditions (e.g.
in high-performance driving): slow down and, if the
warning light stays on, stop the vehicle. Wait for 2 or 3
minutes with the engine running and slightly
accelerated to further favour the coolant circulation,
then stop the engine. Check the correct coolant level as
described above.
IMPORTANT Over demanding routes, it is advisable to
keep the engine on and slightly accelerated for a few
minutes before switching it off.
redLOW BATTERY CHARGE
The warning light comes on when the
ignition key is turned to MAR-ON, but it
should go out as soon as the engine has
started (with the engine running at idle
speed a brief delay before going out is
acceptable).If the warning light stays on, contact a Fiat Dealership
immediately.

ENGINE OIL
47)
Check the oil level a few minutes (about
5) after the engine has stopped, with
the vehicle parked on level ground.
The oil level must be between the MIN
and MAX marks on the dipstick B
fig. 237 - fig. 238 - fig. 239.
The range between the MIN and MAX
marks corresponds to about 1 litre
of oil.
If the oil level is near or under the MIN
mark, add oil through the filler A fig. 237
- fig. 238 - fig. 239, until it reaches the
MAX mark.
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 vehicle is new, the engine
needs to be run in, therefore the engine
oil consumption can only be considered
stabilised after the first 5,000–6,000
km.
IMPORTANT The oil consumption
depends on driving style and the
conditions under which the vehicle is
used.
IMPORTANT After adding or changing
the oil, let the engine run for a few
seconds and wait a few minutes after
switching it off before checking the
level.
IMPORTANT Always top up using
engine oil of the same specifications as
that already in the engine.ENGINE COOLANT
48)
177)
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 to low, operate as follows:
❒remove the plastic cover A fig. 240,
rotating the locking screws B fig.
240 counter-clockwise, to access the
filler of the reservoir;
❒slowly pour a mixture of 50%
demineralised water and 50%
PARAFLU
UP
from PETRONAS
LUBRICANTS through the reservoir
filler C fig. 237 - fig. 238 - fig. 239
until the level is close to MAX.
A 50-50 mixture of PARAFLU
UP
and
distilled water gives freeze protection
up to –35°C.
When the vehicle is used in particularly
harsh weather conditions, we
recommend using a 60-40 mixture of
PARAFLU
UP
and demineralised water.
