Otherwise wait for few seconds to al-
low the engine cooling, then open
slowly and carefully the cap, top up
coolant and check whether its level is
falling between MINand MAXmarks
in the reservoir. Check visually any
leak. If, when restarting, the warning
light comes on again, contact Fiat
Dealership.
–vehicle heavy duty(e.g.: towing
trailer uphill of fully laden vehicle): de-
crease speed, if the warning light stays
on, stop the vehicle. Wait for 2 or 3
minutes leaving the engine on and
slightly accelerated to further activate
the circulation of the coolant fluid,
then switch the engine off. Check
proper coolant level as described pre-
viously.

AIR BAG FAILURE
(red) (where provided)
Turning the ignition key to
MARthe warning light turns
on, but it should go off after
few seconds.
The warning light stays on glowing
steadily if there is a failure in the air
bag system.
On certain versions the dedicated
message is displayed.

The failure of the warn-
ing light
¬(warning light
off) is also indicated by
the flashing for more than the

If when turning the igni-
tion key to MAR, the
warning light
¬does not
turn on or stays on when travel-
ling there could be a failure in
safety systems; in this event air
bags or pretensioners could not
trigger in case of impact or, in a
minor number of cases, they
could trigger accidentally. Con-
tact Fiat Dealership immediate-
ly to have the system checked.

110DRIVING YOUR VEHICLE
Some suggestions which may help
you to keep the running costs of the
vehicle down and lower the amount
of toxic emissions released into the at-
mosphere are given below.
GENERAL
CONSIDERATIONS
Vehicle maintenance
The overall state of the vehicle is an
important factor which has a marked
influence over fuel consumption and
driving comfort and on the life span of
your vehicle. For this reason care
should be taken to maintain your ve-
hicle by carrying out the necessary
checks and regulations in accordance
with the specifications given in the
SERVICE SCHEDULE (see sections:
spark plugs, idling, air cleaners, diesel
fuel filter, timing).Tyres
Tyre pressure should be checked at
least once every four weeks: if the
pressure is too low fuel consumption
increases as the resistance to the
rolling movement of the tyre is
greater. In this state, tyre wear is in-
creased and handling suffers which will
effect safety.
Unnecessary loads
Do not travel with too much load in
the boot. The weight of the vehicle
and its trim greatly effects consump-
tion and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack
from the roof as soon as they are no
longer used.
These accessories reduce the aero-
dynamic penetration of the vehicle and
will increase consumption. Whentransporting particularly large objects,
use a trailer, where possible.
Electric devices
Use electric devices for the neces-
sary time only. The heated rear win-
dow, fog lights, windscreen wipers,
heater fan require large amounts of
electricity and increasing the request
for power will also increase fuel con-
sumption (up to +25% when driving in
towns).
Climate control system
The climate control system is an ad-
ditional load which greatly effects the
engine leading to higher consumption
(up to +20% in average). When the
temperature outside allows, use the
air vents where possible.
Aerodynamic accessories
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.
CONTAINING RUNNING COSTS AND POLLUTION

TOWING TRAILERS
IMPORTANT NOTES
The vehicle must be fitted with a ho-
mologated tow hitch and suitable elec-
trical system for towing a caravan or
trailer. Installation must be carried out
by skilled personnel who will issue
documentation authorising circulation
on the road.
Install any specific and/or additional
rear-view mirrors in accordance with
the Highway Code.
Remember that towing a trailer
makes it harder for the vehicle to
climb the maximum gradients speci-
fied.Engage a low gear when driving
downhill rather than constantly brak-
ing.
The weight the trailer exerts on the
vehicle’s tow hitch coupling reduces
the vehicle’s payload by the same
amount.
To make sure the maximum towable
weight is not exceeded (given in the
log book) account should be taken of
the fully laden trailer, including acces-
sories and personal belongings.
Respect the speed limit for towing
trailers in the country you are travel-
ling in. In any case, do not exceed a
maximum speed of 100 km/h. Do not allow anything to
be sprayed onto the cat-
alytic converter, lambda
sensor and exhaust pipe.
When functioning nor-
mally the catalytic con-
verter reaches high tem-
peratures. For this reason do not
park the vehicle over inflamma-
ble material (grass, dry leaves,
pine needles etc.): fire hazard.
Ignoring the above rules
may lead to fire.
113DRIVING YOUR VEHICLE

114DRIVING YOUR VEHICLE
The tow hitch must comply with the
current regulation, with reference to
Directive 94/20/EC and amendments.
Install a tow hitch which is suitable
for the towing capacity of the vehicle.
Use a unified coupling for the elec-
trical connections. The coupling is gen-
erally fitted on a specific mount fas-
tened to the tow hitch.
For electrical connection, a 7 or 13
pole 12VDC coupling must be used
(CUNA/UNI and ISO/DIN standards).
Follow the instructions provided by
the manufacturer of the vehicle and/or
the tow hitch.
Use the specific trailer light fusebox
for electrical connections.
An electric brake should be supplied
directly by the battery through a cable
with a cross section of no less than 2.5
mm
2.In addition to the electrical connec-
tion, only the lead for powering an
electric brake and the lead to power
a light inside the trailer not exceed-
ing 15W may be connected to the ve-
hicle’s electrical system.
For connections use the preset con-
trol unit with battery cable no less
than 2,5 mm
2.
FITTING DIAGRAM
The trailer tow hitch is to be fixed in
the points indicated (see diagram fig.
4).
The plate 1must have a minimum
thickness of 6 mm. The fastening
points 2will be equipped with shims
’16 x 2 mm. The tow hitch structure
is fastened in the points shown with Ø
by means of six M8 screws and four
M10 screws.
Fasten the tow hitch to the body and
trim the bumper with the frame pro-
vided with the assembly kit.
After fitting the tow hitch, the emp-
ty vehicle weight will increase by ap-
proximately 15.5 kg. The ABS system will not
control the trailer braking
system. Great care
should therefore be taken when
driving on slippery road surfaces.
Under no circumstances
modify the vehicle’s brak-
ing system for trailer
braking control. The trailer’s
braking system must be com-
pletely independent of the vehi-
cle’s hydraulic system.
TOW HITCH INSTALLATION
The towing device should be fas-
tened to the body by specialised per-
sonnel according to any additional
and/or integrative information supplied
by the Manufacturer of the device.

153VEHICLE MAINTENANCE
IMPORTANT - Engine oil
Should prevailing use of the vehicle
be under one of the following special-
ly heavy conditions:
– towing a trailer
– on dirty roads
– for short, repeated trips (less than
7-8 km) with outside temperature be-
low zero
– frequently idling engines or long
distance low speed driving (e.g. taxis
or door-to-door deliveries) or in case
of a long term inactivity; replace en-
gine oil more frequently than required
on Service schedule
IMPORTANT - Air cleaner
If the vehicle is used on dusty roads
change the air cleaner more frequently
than the indications in the Service
schedule. If in doubt as to how often
the engine oil and air cleaner should
be changed according to how you use
the vehicle, contact a Fiat Dealer-
ship.IMPORTANT - Pollen filter
If the vehicle is used frequently in
dusty or heavily polluted environ-
ments it is advisable to replace the fil-
tering element more frequently; in
particular it should be replaced if a re-
duction of the amount of air admitted
to the passenger compartment is not-
ed.
IMPORTANT - Battery
The charge in your battery should be
checked, where possible at the start
of the winter, to limit the risk of the
battery electrolyte freezing. This check
should be carried out more frequent-
ly if the vehicle is mainly used for short
trips or if it is fitted with accessories
that permanently take in electricity
even when the ignition key is re-
moved, especially in the case of after
market accessories.You should check the battery fluid
(electrolyte) level more frequently
than shown in the service schedule in
this chapter if the vehicle is used in hot
climates or particularly demanding
conditions.
Maintenance of your ve-
hicle should be entrusted
to a Fiat Dealership. For
ordinary routine maintenance
operations which you are able to
carry out yourself, ensure that
you have the necessary tools and
original Fiat spare parts and flu-
ids available. Do not carry out
servicing operations if you have
no experience.
