TOWING TRAILERS
IMPORTANT NOTES
The vehicle must be provided with a type-approved tow
hitch and adequate electrical system to tow trailers. In-
stallation must be performed by specialised personnel who
will issue the required papers for travelling on roads.
Install any specific and/or additional rear-view mirrors in
accordance with the highway code of the country in which
you are travelling.
Remember that when towing a trailer, steep hills are hard-
er to climb, braking distances increase and overtaking takes
longer depending on the overall weight of the trailer.
Engage a low gear when driving downhill, rather than con-
stantly using the brake.
The weight of the trailer on the vehicle tow hitch will re-
duce the loading capacity of the vehicle by the same
amount.
Consider the weight at full load, including accessories and
luggage, to make sure you do not exceed the maximum
towable weight (shown in the log book).
Respect each country’s speed limits for vehicles towing
trailers. In all cases, the top speed must not exceed
80 km/h. CONDITIONS OF USE
Cold starting
Short distances and frequent cold start-ups prevent the
engine from reaching its optimum running temperature.
Consequently, both consumption (from +15 to +30% on
the urban cycle) and emissions will increase.
Traffic and road conditions
Heavy traffic, for instance when travelling in a queue with
frequent use of low gears or in cities with lots of traffic
lights, causes fairly high fuel consumption. Mountain roads
and uneven surfaces also have a negative effect on con-
sumption.
Traffic hold-ups
During prolonged hold-ups (e.g. at level crossings) the en-
gine should be switched off.

A specific message is displayed on certain versions.
Under these conditions, the vehicle can continue trav-
elling at moderate speed without demanding excessive
effort from the engine. Prolonged use of the vehicle
with the warning light on may cause damage. Go to a
Fiat Dealership as soon as possible.
The warning light goes out after the fault disappears,
but the notification is stored in the system.
❒flashing: this indicates possible damage to the catalytic
converter (see “EOBD system” in the “Dashboard and
controls” section).
If the light flashes, come off the accelerator pedal to re-
duce engine revs until the warning light stops flashing;
continue the journey at moderate speed, trying to avoid
driving conditions that may cause further flashing, and
get to a Fiat Dealership as soon as possible. INJECTION SYSTEM FAILURE
(Multijet versions – amber)
EOBD ENGINE MANAGEMENT
SYSTEM FAILURE
(petrol versions – amber)
Injection system failure
Under normal conditions, turning the ignition key to MAR,
the warning light turns on but it should go off after the en-
gine starts. If the warning light stays on or comes on when
travelling, it means there is a fault in the injection system
which could cause loss of performance, poor handling and
high fuel consumption levels.
A specific message is displayed on certain versions.
Under these conditions, the vehicle can continue travel-
ling at moderate speed without demanding excessive ef-
fort from the engine. In any case, you should go to a Fiat
Dealership as soon as possible.
EOBD engine management system failure
Under normal conditions, turning the ignition key to MAR,
the warning light turns on but it should go off after the en-
gine starts.
This indicates that the warning light is working correctly.
If the warning light either stays on or comes on during
your journey:
❒on permanently: this means there is a fault in the sup-
ply/ignition system which could cause high exhaust
emissions, loss of performance, poor handling and high
fuel consumption levels.
U
Go to a Fiat Dealership as soon as possi-
ble if warning light
Udoes not light up
when the key is turned to MAR or if, while
travelling, the warning light comes on either per-
manently or flashing (along with a message on the
display on certain versions). The operation of the
Uwarning light may be checked by traffic police
using appropriate equipment. Respect the regula-
tions in force in the country where you are driving.

FUEL RESERVE
(amber)
When the ignition key is turned to MAR, the
warning light turns on but should go off after a few
seconds.
The warning light turns on when 8-10 litres of fuel are
left in the tank.
IMPORTANT The warning light will blink to indicate a sys-
tem failure. If this happens, go to a Fiat Dealership to have
the system checked. DPF (PARTICULATE FILTER)
CLEANING IN PROGRESS
(only Multijet versions with DPF
– amber)
When the ignition key is turned to MAR, the warning light
turns on but should go off after a few seconds. The warn-
ing light stays on constantly to notify the driver that the
DPF system needs to eliminate captured pollutants (par-
ticulate) by the regeneration process.
The warning light does not come on during every DPF
regeneration, but only when driving conditions require no-
tification to the driver.
The warning light will go off if the vehicle stays in motion
until regeneration has been completed. The process nor-
mally takes about 15 minutes. Optimum conditions for
completing the process are achieved by travelling at
60 km/h with engine revs above 2000 rpm.
If this warning light comes on, it does not mean the vehi-
cle is defective, so there is no need to take it to a garage.
A specific message will appear on the display when the
warning light comes on (for versions/markets where pro-
vided).
h
ç
Always drive at a speed appropriate to the
traffic conditions, the weather and speed
limits. The engine may be turned off while the DPF
light is on; however, repeated interruption of the re-
generation process may result in premature degra-
dation of the engine oil. For this reason, it is always
advisable to wait for the light to go off before turn-
ing off the engine, following the instructions ap-
pearing above. It is recommended to complete DPF
regeneration with the vehicle stationary.

GLOW PLUG PREHEATING FAULT
(Multijet versions – amber)
Glow plugs preheating
This warning light comes on when the key is turned to
MAR. It will go out as soon as the glow plugs have reached
a preset temperature. Start the engine as soon as the warn-
ing light goes out.
IMPORTANT In hot outside temperatures, the warning
light may stay on for only a very short time.

WATER IN DIESEL FILTER
(Multijet versions – amber)
When the ignition key is turned to MAR, the
warning light turns on but should go off after a few
seconds.
The warning light
cturns on when there is water in the
diesel filter. A specific message is displayed on certain ver-
sions.
c
The presence of water in the fuel supply cir-
cuit may cause severe damage to the in-
jection system and irregular engine opera-
tion. If warning light
ccomes on (with a message
on the display on some versions), go to a Fiat Deal-
ership as soon as possible to have the system bled.
Water may have entered the tank if this appears
immediately after refuelling: if this happens, switch
the engine off immediately and contact a Fiat Deal-
ership.

Strictly avoid using a rapid battery charg-
er for jump starting: this could damage the
system electronics and the ignition and en-
gine supply control units.
This procedure must be performed by ex-
perts because incorrect actions may cause
considerable electrical discharge. Furthermore,
battery fluid is poisonous and corrosive: avoid con-
tact with skin and eyes. Keep naked flames and
lit cigarettes away from the battery. Do not cre-
ate sparks.
WARNING
BUMP STARTING
Never bump start the engine by pushing, towing or driving
downhill. This could cause fuel to flow into the catalytic
converter and damage it beyond repair.
IMPORTANT Remember that the brake booster and the
power steering system are not active until the engine is
started, so you will need to apply much more force to
the brake pedal or steering wheel.
CHANGING A TYRE
The vehicle is originally equipped with the Fix&Go auto-
matic quick tyre repair kit (see instructions in the next sec-
tion). As an alternative, the vehicle may have a normal-
sized spare wheel.
Wheel changing and correct use of the jack and spare
wheel call for some precautions, as listed below.
