2018 FIAT DOBLO COMBI fuel pressure

The cold tyre inflation pressure must
not exceed the maximum inflation
pressure value printed on the side of
the tyre.
NOTE
The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
Therefore, the TPMS should not be
used as pressure switch while adjusting
the tyre inflation pressure.
Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency and
tyre tread life and may also affect
handling and braking performance of
the vehicle.
The TPMS does not replace the
correct tyre maintenance. It is up to the
driver to maintain the correct tyre
pressure level measuring it with
a suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light
to switch on.
The TPMS warns the driver of any
condition of insufficient tyre pressure. If
this drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
The seasonal temperature changes
affect tyre pressure.
IMPORTANT Monitoring and
maintaining the correct pressure in all
four tyres are particularly important.
Tyre pressure monitoring system
low pressure warning
IMPORTANT In the case of deflation of
more than one tyre sequentially, without
switching off and on the engine, from
the second tyre involved the acoustic
signal is not activated, only the
dedicated signal is shown on the
display.
To prevent the signal from being stored
in the event of pressure loss of a
subsequent tyre (with deactivation of
the acoustic signal), the ignition key
must be turned to MAR and then to
STOP, each time pressure is restored.
TPMS operation faults
The system fault is indicated by the
warning light
which first flashes for
75 seconds and then stays on steadily.
WARNING
101)The TPMS is optimised for the original
tyres and wheels provided. TPMS
pressures and alerts have been defined
according to the size of the tyres mounted
on the vehicle. Using equipment with
different size, type or kind may cause
irregular system operation or sensor
damage. Non-original spare wheels can
damage the sensor. Do not use tyre
sealant or balancing weights if the vehicle
is equipped with TPMS as these may
damage the sensors.
102)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
103)The TPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not even to be
considered a replacing system for
maintenance or a safety system
104)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.
105)The TPMS cannot indicate sudden
tyre pressure drops (for example when
a tyre bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.
112
STARTING AND DRIVING

106)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
107)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
108)Always refit the valve stem cap after
inspecting or adjusting tyre pressure.
This prevents dampness or dirt from
entering the valve stem and thus
the pressure control sensor from being
damaged.
109)The tyre repair kit (Fix&Go) provided
with the vehicle (for versions/markets,
where provided) is compatible with the
TPMS sensors; using sealants not
equivalent with that in the original kit may
adversely affect its operation. If sealants
not equivalent with the original ones are
used, it is recommended to have the
TPMS sensor operation checked by a
qualified repair centre.SPEED BLOCK
(for versions/markets, where provided)
The vehicle is equipped with a speed
limitation function that can be set at the
user's request to one of four predefined
values: 90, 100, 110, 130 km/h.
To activate/deactivate this function,
contact a Fiat Dealership.
Following the operation, a sticker will be
applied to the windscreen showing the
top speed setting.
IMPORTANT The speedometer could
indicate a higher maximum speed than
the effective one, set by the Dealership,
in accordance with the regulations in
force.
CRUISE CONTROL
(for versions/markets, where provided)
IN BRIEF
This is an electronic driving aid that
allows you to drive at a speed of
above 30 km/h on long and straight
dry roads (e.g. motorways) with
few driving changes at a preset
speed without having to press the
accelerator pedal. It is therefore not
recommended to use this device
on extra-urban roads with traffic. Do
not use it in town.
Activating the device
When the device is activated, warning
light
comes on together with the
relevant message in the instrument
panel (for versions/markets where
provided).
The speed adjustment function cannot
be activated in 1st or reverse gear; it
is advisable to activate the function
in 4th or higher gears.
When travelling downhill with the device
activated, the vehicle speed may
exceed the memorised one.

If they are open, they can cause the
system to send false signals: always
close the rear doors.
Do not apply stickers to the sensors.
WARNING
112)The sensor must be free of mud, dirt,
snow or ice in order for the system to
work. Be careful not to scratch or damage
the sensors while cleaning them. Avoid
using dry, rough or hard cloths. The
sensors must be washed using clean
water, with the addition of vehicle
shampoo if necessary. When using special
washing equipment such as high pressure
jets or steam cleaning, clean the sensors
very quickly keeping the jet more than
10 cm away.
113)Parking manoeuvres, however, are
always the driver’s responsibility. While
carrying out these manoeuvres, always
make sure that no people (especially
children) or animals are in the area
concerned. The parking sensor is designed
to assist drivers, who must still never
allow their attention to lapse during
potentially dangerous manoeuvres even if
performed at low speed.
REFUELLING THE
VEHICLE
PETROL ENGINES
Only use unleaded petrol, with an
octane number (R.O.N.) not lower than
95.
IMPORTANT Never use leaded petrol,
even in small amounts or in an
emergency, as this would damage the
catalytic converter beyond repair.
DIESEL ENGINES
Operation at low temperatures
Only use Diesel for motor vehicles
(EN590 specification).
In order to avoid these problems,
different types of Diesel are distributed
according to the season: summer
type, winter type and Arctic type (cold,
mountain areas). If refuelling with diesel
whose specifications are not suitable
for the usage temperature, it is
advisable to mix PETRONAS
DURANCE DIESEL ART additive in the
proportions shown on the container
with the fuel. Pour the additive into the
tank before the fuel.
When using or parking the vehicle for a
long time in the mountains or cold
areas, it is advisable to refuel using
locally available diesel fuel.In this case, it is also advisable to keep
the tank over 50% full.
28)
REFUELLING CAPACITY
To ensure that you fill the tank
completely, top up twice after the first
click of the fuel supply gun. Further
top-ups could cause faults in the fuel
feeding system.
FUEL TANK CAP
Opening
1) Open the flap A fig. 136 by pulling it
outwards, keep the cap B still, insert
the ignition key in the lock and turn
it anticlockwise.
2) Turn the cap anticlockwise and
remove it. The cap has a device C that
attaches it to the flap so it cannot be
lost. When refilling, attach the plug
to the flap, as shown.

Closing
1) Fit the cap (complete with key) and
turn it clockwise until it clicks once
or more.
2) Turn the key clockwise and extract it,
then close the flap.
The sealing may cause a slight pressure
increase in the tank. A little breathing
off, while slackening the cap is
absolutely normal.

NATURAL POWER
VERSIONS
The methane filler is located near the
petrol filler
To access the filler, undo the cap fig.
137 turning it anticlockwise.
The profile of filler fig. 138 for refilling is
the universal type, compatible with
Italian and NGV1 standards.In some European countries adapters
are considered ILLEGAL (e.g. in
Germany).
For service stations with cubic metre
(m
3) nozzles (pressure differential)
the check valves must be released by
delivering a small amount of methane to
measure the residual pressure in the
cylinder.
The plates (provided with the vehicle
documentation) contain the date for the
first inspection of the cylinders.

IMPORTANT Note that when using a fuel like methane, the range is extremely variable because in addition to the vehicle
maintenance and driving conditions it also depends on the temperature of the gas in the cylinder. The methane actually heats
up during the refuelling and cools down whilst driving, undergoing variations in pressure that reduce the quantity that can
be used. It should also be pointed out that whilst the vehicle is being run in (up to around 3000 km) the fuel consumption may
be higher than the figures given.
