2016 FIAT FULLBACK engine coolant

engine coolant temperature is low. In
such a case, the engine revolutions do
not rise to over 5,000 rpm even if the
accelerator pedal is depressed.
Starting the engine (diesel-powered
vehicles)
Except for vehicles equipped with
the keyless operation system
Insert the ignition key and fasten the
seat belt.
Make sure the parking brake is
applied.
Depress and hold the brake pedal.
On vehicles equipped with M/T,
depress the clutch pedal all the way
and place the gearshift lever in the “N”
(Neutral) position. On vehicles equipped
with A/T, make sure the selector lever is
in the “P” (PARK) position.
Turn the ignition key to the “ON”
position. The diesel preheat indicator
lamp will first illuminate, and then after a
short time go out, indicating that
preheating is completed.
Turn the ignition key to the “START”
position without depressing the
accelerator pedal, and release it when
the engine starts.If the engine is cold, the diesel preheat
indicator lamp is on for a longer time.
When the engine has not been started
within about 5 seconds after the diesel
preheat indicator lamp went out, return
the ignition switch to the “LOCK”
position. Then, turn the switch to the
“ON” position to preheat the engine
again.
When the engine is warm, the diesel
preheat indicator lamp does not come
on even if the ignition key is placed in
the “ON” position. Start the engine by
turning the ignition key right to the
“START” position.
Minor noises may be heard on engine
startup. These will disappear as the
engine warms up.For vehicles equipped with the
keyless operation system
Fasten the seat belt.
Make sure the parking brake is
applied.
Press and hold the brake pedal
down firmly with your right foot.
On vehicles equipped with M/T,
depress the clutch pedal all the way
and place the gearshift lever in the “N”
(Neutral) position. On vehicles equipped
with A/T, make sure the selector lever is
in the “P” (PARK) position.
Press the engine switch. The diesel
preheat indicator lamp will first
illuminate, and then after a short time
go out, indicating that preheating is
completed. The engine will start.
When the engine is not started, it may
become hard to depress the brake
pedal and the vehicle may not be able
to detect the pedal operation. Therefore
the engine may not be started. In such
a case, depress the brake pedal more
firmly than usual.
If the engine is cold, the diesel preheat
indicator lamp is on for a longer time.
Putting the operation mode in ON will
also start preheating the engine. When
the engine has not been started within
about 5 seconds after the diesel
preheat indicator lamp went out, put
the operation mode in OFF. Then,
attempt the engine start procedure to
preheat the engine again.

ENGINE
OVERHEATING
When the engine is overheating,will
blink. If this occurs, take the following
corrective measures:
1. Stop the vehicle in a safe place.
2. Check whether steam is coming from
the engine compartment.
If steam does not come from the engine
compartment: with the engine still
running, raise the bonnet to ventilate
the engine compartment.
If steam is coming from the engine
compartment: stop the engine, and
when the steam stops, raise the bonnet
to ventilate the engine compartment.
Restart the engine.
248) 249) 250)
3. Confirm that the cooling fan (B) is
turning.
If the cooling fan is turning: after the
high coolant temperature warning has
gone off, stop the engine
If the cooling fan is not turning: stop the
engine immediately and contact a Fiat
dealership for assistance.A — Radiator cap
B — Cooling fan
C — Reserve tank
251)
4. Check the coolant level in the reserve
tank (C).
5. Add coolant to the radiator and/or
reserve tank if necessary (refer to the
“Maintenance” section).
252)
131)
6. Examine the radiator hoses for
coolant leakage and the drive belt for
looseness or damage.
If there is anything wrong with the
cooling system or drive belt, have the
problem corrected at a Fiat Dealership.
WARNING
248)Do not open the bonnet while steam
is coming from the engine compartment. It
could cause steam or hot water to spurt
out, causing burns. Hot water could spurt
out even when there is no steam coming
out, and some parts will be very hot. Be
very careful when opening the bonnet.
249)Be careful of hot steam, which could
be blowing off the reserve tank cap.
250)Do not attempt to remove the radiator
cap while the engine is hot.
251)Be careful not to get your hands or
clothes caught in the cooling fan.
252)Make sure that the engine has cooled
down before removing the radiator cap (A),
because hot steam or boiling water
otherwise will gush from the filler port and
may scald you.

IMPORTANT
131)Do not add coolant while the engine is
hot. Suddenly adding cold coolant could
damage the engine. Wait for the engine to
cool down, then add coolant a little at a
time.
BLEEDING THE FUEL
SYSTEM
The fuel system should be bled to
remove air as described below if the
fuel supply is exhausted during travel.
Pump the hand pump (A) at the top of
the fuel filter until the hand pump
becomes stiff.
Then try again to start the engine. If the
engine does not start, repeat the
process above.
253) 254)
WARNING
253)Do not smoke or have any other open
flame near the vehicle while bleeding the
fuel system.
254)Be sure to carefully clean away any
spilt fuel which could ignite and cause a
fire.
REMOVAL OF WATER
FROM THE FUEL
FILTER
If the fuel filter indicator lamp in the
instrument panel illuminates during
driving, it indicates that water has
accumulated in the fuel filter. If this
occurs, remove the water as described
below.
1. Loosen the drain plug (A) of the fuel
filter.
2. Operate the hand pump (B) slowly
6 or 7 times in order to force the water
out through the drain plug (A).
