103GETTING TO KNOW YOUR VEHICLE
If the outside temperature is very
low, the diesel thickens due to the for-
mation of paraffin and could clog the
fuel filter.
In order to avoid these problems, dif-
ferent types of diesel are distributed
according to the season: summer type,
winter type and arctic type (cold
mountain areas).
If refuelling with diesel fuel not ade-
quate, you are recommended to add
TUTELA DIESEL ARTto the fuel,
in the proportions written on the con-
tainer. Pour the antifreeze into the fu-
el tank before the fuel.
REFUELLING
To guarantee full tank filling, carry
out two refuelling operations after the
first click of the fuel delivery gun.
Avoid further topping up operations
that could cause damages to the fuel
system.FUEL FILLER CAP fig. 150
Make sure that the left-
hand sliding side door is
completely closed before
refuelling. You could damage the
door and the sliding lock system
which comes into play when the
fuel flap is open.
You cannot open the
left-hand sliding side door
while refuelling when the
flap is open.

To open:
1)Turn the cap by approximately half
a turn anticlockwise and remove it.
IMPORTANTThe hermetic clo-
sure may cause a slight pressure in the
tank: a slight hissing when turning the
cap is quite normal.
2)While you are filling up, place the
cap on the fuel filler flap as illustrated
in the figure.
To close:
The cap has a bayonet coupling. In-
sert the cap and turn it clockwise un-
til it clicks once or more.

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.

ANNUAL
INSPECTION
SCHEDULE
For vehicles with an annual
mileage of below 20.000 km (for
example about 10.000 km) the
following yearly inspection pro-
gramme is advised:
– check tyre conditions/wear and ad-
just pressure if required (including the
spare wheel).
– check light system operation (head-
lights, direction indicators, hazard
lights, boot lights, passenger compart-
ment lights, glovebox light, warning
lights, etc.).
– check windscreen wiper/washer
operation, adjust nozzles.
– check windscreen/rear window
blade position/wear
– check front disk brake pad condi-
tions and wear.– check cleanness of bonnet and
boot locks and lever cleanness and lu-
brication
– sight inspect the conditions of: en-
gine, gearbox, transmission, pipes and
hoses (exhaust - fuel - brakes), rubber
parts (boots, sleeves, bushes, etc)
brake and fuel hoses.
– check battery charge.
– visual check on various drive belt
conditions.
– check and top up, if required, fluid
levels (engine coolant, brake fluid,
windscreen washer fluid, battery fluid,
etc.).
– change engine oil.
– change engine oil filter.
– replace pollen filter (where pro-
vided).
ADDITIONAL
CHECKS
Every 1,000 kmor before long
trips, check and top up as necessary:
engine coolant level, brake fluid level,
windscreen washer liquid level, tyre
pressure and conditions.
Every 3,000 km check and top up
as necessary: engine oil level.
You are recommended to use FL
Selenia,products designed and pro-
duced specifically for Fiat vehicles (see
“Capacities” in section “Technical
specifications”).

PRACTICAL TIPS TO
REDUCE CONSUMPTION
AND ENVIRONMENTAL
POLLUTION
Vehicle conditions
1. Have checks and adjustments
carried out in accordance with the
“Scheduled Service Plan”.
2. Check the tyre pressure at inter-
vals of not more than 4 weeks (see
“Tyre pressure”). Too low tyre pres-
sure increases consumption as the
rolling resistance increases. In these
conditions the tyres wear faster and
performance deteriorates.
3. Use winter tyresonly in the sea-
sons where dictated by the climatic
conditions. Winter tyres not only in-
crease consumption but also tyre
noise.4. Do not travel in heavy load con-
ditions(vehicle overloaded): The
weight of the vehicle (especially when
driving in town) and its trim greatly af-
fect fuel consumption and stability.
5. Remove roof racks or ski racks
after use. These accessories reduce
the aerodynamics of the vehicle and
have a negative effect on fuel con-
sumption.
6. Ideally use a trailerto transport
particularly bulky objects.
7. It is preferable to use the air vents:
driving with the window open has a
negative effect on the aerodynamics of
the vehicle.
8. Use the electrical devices only for
the time strictly necessary. The rear
heated window, additional headlights,
windscreen wipers and heater fan
need a considerable amount of ener-
gy, consequently increasing fuel con-
sumption (up to 25% more in the ur-
ban cycle).9. Using the air-conditioning in-
creases consumption (up to 30% more
on average): use the air vents when
the outside temperature permits.
Driving style
1. After starting the engineit is
advisable to set off immediately and
slowly avoiding revving up the engine.
Do not warm up the engine with the
vehicle stationary either at idle or at
high speed: in these conditions the en-
gine in fact warms up more slowly, in-
creasing consumption, emissions and
wear of the mechanical devices.
2. Avoid revving upwhen starting
at traffic lights or before turning off the
engine. This action, like double-de-
clutching, is unnecessary and causes in-
creased fuel consumption and pollu-
tion.
