2018 FIAT DOBLO COMBI oil change

SYMBOLS
Some vehicle components have coloured labels whose symbols indicate precautions to be observed when using this
component.
A plate summarising these symbols can also be found under the bonnet.
VEHICLE MODIFICATIONS/ALTERATIONS
IMPORTANT Any modification or alteration of the vehicle might seriously affect its safety and road holding, thus causing
accidents, in which the occupants could even be fatally injured.
ACCESSORIES PURCHASED BY THE OWNER
If after buying the vehicle, you decide to install electrical accessories that require a permanent electrical supply (e.g. radio,
satellite anti-theft system, etc.) or accessories that in any case burden the electrical supply, contact a Fiat Dealership, whose
personnel will check whether the vehicle's electrical system is able to withstand the load required, or whether it needs to be
integrated with a more powerful battery.
IMPORTANT Take care when fitting additional spoilers, alloy wheel rims or non-standard wheel hubs: they could reduce the
ventilation of the brakes and affect efficiency under sharp, repeated braking or on long descents. Make sure that nothing
obstructs the pedal stroke (mats, etc.).
INSTALLING ELECTRICAL/ELECTRONIC DEVICES
Electrical and electronic devices installed after buying the vehicle and available as after-sales must carry the following label: Fiat
authorises the installation of transceivers provided that installation is carried out at a specialised centre, in a workmanlike
fashion and in compliance with manufacturer's specifications.
IMPORTANT Traffic authorities may not allow the vehicle on the road if devices are fitted that involve modifications to the
features of the vehicle. This may also cause lapse of the warranty in relation to faults caused by the change or either directly or
indirectly related to it. Fiat shall not be liable for damage caused by the installation of accessories either not supplied or
recommended by Fiat and/or not installed in compliance with the provided instructions.

Warning lights on
panelWhat it means What to do
redLOW ENGINE OIL PRESSURE
When the key is turned to MAR, the digital warning light switches on, but it should
switch off as soon as the engine is started.
The warning light switches on constantly together with the message in the display
when the system detects that the engine oil pressure is insufficient.
13)
ENGINE OIL DETERIORATED
(MultiJet versions with DPF only)
The warning light starts to flash together with a message on the display (for
versions/markets, where provided) when the system detects that the engine oil
has deteriorated.
If the warning light flashes, this does not mean that the vehicle is faulty, but simply
informs the driver that it is now necessary to change the engine oil as a result of
regular vehicle use. If the oil is not changed, warning light
will also come on
and engine operation is limited to 3000 rpm when a second threshold is reached.
If the oil is still not changed, when a third deterioration threshold is reached, the
engine is limited to 1500 rpm to avoid damage.Contact a Fiat Dealership as
soon as possible.
47) 48)
Remember that the
deterioration of the engine oil
is accelerated by:
– mainly town use of the
vehicle which makes the DPF
regeneration process more
frequent
– use of the vehicle for short
trips, preventing the engine
from reaching operating
temperature
– repeated interruption of the
regeneration process,
signalled by the DPF warning
light coming on.

Warning lights on
panelWhat it means What to do
redLOW ENGINE OIL LEVEL
When turning the ignition key to MAR, the warning light turns on but it should go
off after a few seconds.
This warning light appears on the panel when the engine oil level falls below the
minimum recommended value.
On certain versions a dedicated message is displayed.Restore the correct engine oil
level (see “Checking fluid
levels” in the "Maintenance
and care" section).
redDOOR OPEN
On some versions the warning light turns on when one or more doors or the rear
swing doors/tailgate (for versions/market, where provided) are not properly closed.
A buzzer will sound when doors/tailgate are open and the vehicle is moving.Check that all doors or the
swing doors/tailgate (for
versions/markets, where
provided) are perfectly
closed.
WARNING
44)If thewarning light turns on while driving (on certain versions together with the message on the display) stop the car immediately and
contact a Fiat Dealership.
45)If the
warning light does not switch on when the key is turned to MAR or if it stays on while driving (together with the message on the
display), there may be an anomaly in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an
accident or, in a lower number of cases, they could deploy erroneously. Before continuing, contact a Fiat Dealership to have the system
checked immediately.
46)A failure of the
warning light is indicated by the blinkingwarning light. In this case, thewarning light may not indicate a possible
problem with the airbag restraint system. Before continuing, contact a Fiat Dealership to have the system checked immediately.
47)If the
warning light comes on, the exhausted engine oil should be changed as soon as possible, never drive more than 500 km from
the first switching-on of this warning light. Failure to observe the above may result in severe damage to the engine and invalidate the warranty.
Remember that when this warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you do not need to top
up the engine oil.
48)If the
warning light flashes when driving, contact a Fiat Dealership.

SERVICING AND CARE

NB Carefully clean the reservoir cap E
and surrounding surfaces.
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.
IMPORTANT Brake fluid absorbs
moisture. For this reason, if the vehicle
is mainly used in areas with a high
degree of atmospheric humidity, the
fluid should be replaced at more
frequent intervals than specified in the
“Service Schedule”.
43)
136) 137)
POWER STEERING FLUID
Check that the oil level with the vehicle
on flat ground and the engine cold is
between the MIN and MAX marks
on the reservoir body G fig. 190 - fig.
191 - fig. 192 - fig. 193 - fig. 194 - fig.
195 - fig. 196 - fig. 197 - fig. 198.
The level may exceed the MAX mark
when the oil is hot.
If topping up is required, make sure the
oil you use has the same specifications
as that already in the system.

WARNING
132)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of
fire.
133)When the engine is hot, take care
when working inside the engine
compartment to avoid burns. Remember
that when the engine is hot, the fan may
operate: danger of injury. Scarves, ties and
other loose clothing might be pulled by
moving parts.
134)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.135)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.
136)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.
137)The symbol
, on the brake fluid
container indicates if a brake fluid is
synthetic or mineral­based. Using
a mineral-type fluid will damage the special
rubber seals of the braking system beyond
repair.
138)Prevent power steering fluid from
coming into contact with hot engine parts:
it is flammable.
WARNING
40)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 vehicle.
41)Do not add oil with specifications other
than those of the oil already existing in
the engine.
