KNOWING THE INSTRUMENT PANEL

STARTING THE
ENGINE
The vehicle is fitted with an electronic
engine lock device: if the engine fails to
start, see the paragraph “The Fiat
CODE system” in section “Know your
vehicle”.
27) 28)
134)
PROCEDURE
Proceed as follows:
❒engage the handbrake;
❒put the gear lever into neutral;
❒turn the ignition key to MAR-ON: the
warning lights
andon the
instrument panel will turn on;
❒wait for the warning lights
and
to switch off. The hotter the
engine is, the quicker this will
happen;
❒fully press the clutch pedal without
touching the accelerator;
❒turn the ignition key to AVV as soon
as warning light
switches off.
Waiting too long will waste the
heating work carried out by the glow
plugs.
Release the key as soon as the engine
starts.If the engine does not start at the first
attempt, return the ignition key to STOP
before repeating the starting procedure.
If, when the ignition key is at MAR-ON
the
warning light remains lit, turn
the key to STOP and then back to
MAR-ON; if the warning light remains
lit, try with the other keys provided with
the car.
IMPORTANT Go to a Fiat Dealership
immediately if warning light
stays
on constantly on the instrument panel.
IMPORTANT Never leave the ignition
key in MAR-ON position when the
engine is stopped.
29)
WARMING UP THE
ENGINE JUST AFTER IT
HAS STARTED
Proceed as follows:
❒drive off slowly, letting the engine turn
at medium revs. Do not accelerate
abruptly;
❒do not demand full performance at
first. Wait until the engine coolant
temperature gauge starts moving.
30) 31)
STOPPING THE ENGINE
Turn the ignition key to STOP while the
engine is idling.
32) 33)
IMPORTANT
27) It is advisable not to demand
maximum performance from
your vehicle (e.g. excessive
acceleration, long distances at
high speeds, excessively intense
braking, etc.) during the initial
period of use.
28) When the engine is off, do not
leave the ignition key turned to
MAR-ON to prevent unnecessary
electrical consumption from
draining the battery.
29) If the
warning light flashes
for about 60 seconds after
starting or during prolonged
cranking, this indicates a fault in
the glow plug preheating system.
Use the vehicle normally if the
engine starts, but contact a Fiat
Dealership as soon as possible.
184
STARTING AND DRIVING

Roof rack/ski rack
Remove the roof rack or the ski rack
from the roof after use. These
accessories decrease aerodynamic
penetration of the vehicle and have a
negative effect on fuel consumption.
When transporting particularly large
objects, use a trailer if possible.
Electric devices
Use electrical devices only for the
amount of time needed. The heated
rear window, additional headlights,
windscreen/rear window wipers and
heater fan need a considerable amount
of energy, therefore increasing fuel
consumption (by up to 25% in
the urban cycle).
Climate control system
Air conditioning leads to higher fuel
consumption (on average up to +20%).
If the temperature outside permits, try
and use the ventilation only.
Devices for
aerodynamic control
The use of non-certified spoilers may
adversely affect air drag and fuel
consumption.DRIVING STYLE
The main driving styles that affect fuel
consumption are listed below.
Cranking
Do not warm up the engine at low or
high revs when the vehicle is stationary;
this causes the engine to warm up
more slowly, thereby increasing fuel
consumption and emissions. It is
therefore advisable to move off
immediately, slowly, avoiding high
speeds: in this way the engine will
warm up more quickly.
Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before switching off the
engine. This action and also double
declutching is absolutely pointless on
modern cars and also increases
consumption and pollution.
Gear selection
As soon as the conditions of the traffic
and road permit, use a higher gear.
Using a low gear for faster acceleration
will increase consumption.
In the same way improper use of a high
gear increases consumption, emissions
and engine wear.Max. speed
Fuel consumption increases
considerably with speed. Maintain a
constant speed, avoiding unnecessary
braking and acceleration, which cost
in terms of both fuel consumption and
emissions.
Acceleration
Accelerating violently will greatly affect
consumption and emissions:
acceleration should be gradual.
USAGE CONDITIONS
The main usage conditions that
negatively affect fuel consumption are
listed below.
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach
optimum operating temperature.
This results in a significant increase in
consumption levels (from +15 to +30%
on the urban cycle) and emissions.
189

Traffic and road
conditions
Rather high consumption levels are
linked to situations with heavy traffic, for
instance when travelling in queues
with frequent use of the lower gears or
in cities with many traffic lights. Winding
mountain roads and rough road
surfaces also adversely affect
consumption.
Stops in traffic
During prolonged hold-ups (e.g. level
crossings) the engine should be
switched off.TOWING TRAILERS
IMPORTANT
INFORMATION
The vehicle must be provided with a
type-approved tow hook and adequate
electrical system to tow caravans or
trailers. Installation should be carried
out by specialised personnel who
will issue the required papers for
travelling on roads.
Install any specific and/or additional
door mirrors as specified by the
Highway Code.
Remember that when towing a trailer,
steep hills are harder to climb, the
braking spaces increase and overtaking
takes longer depending on the overall
weight.
Engage a low gear when driving
downhill, rather than constantly using
the brake.
The weight of the trailer on the vehicle
tow hook will reduce the loading
capacity of the vehicle by the same
amount. Consider the weight of the
trailer fully laden, including accessories
and luggage, to make sure you do
not exceed the maximum towable
weight (shown on the vehicle
registration document).Do not exceed the speed limits specific
to each country you are driving in, in
the case of vehicles towing trailers.
In any case, the top speed must not
exceed 100 km/h.
You are advised to fit a suitable
stabiliser to the trailer drawbar.
In the vehicles equipped with parking
sensors, after fitting the tow hook
malfunctioning warnings may be
displayed, as some parts (tow bar, ball
tow hook) may be within the sensor
detection range. In this case the
detection range must be adjusted or
the parking assistance function must be
deactivated.
140) 141)
INSTALLING THE TOW
HOOK
The towing device should be fastened
to the body by specialised personnel
according to any additional and/or
integrative information supplied by the
Manufacturer of the device.
The towing device must meet current
regulations with reference to Directive
94/20/EC and subsequent
amendments.
For any version the towing device used
must match the towable weight of the
vehicle on which it is to be installed.
190
STARTING AND DRIVING

For the electric connection a standard
connector should be used which is
generally placed on a special bracket
normally fastened to the towing device,
and a special ECU for external trailer
light control must be installed on the
vehicle. For the electrical connection, 7
or 13 pin 12 V DC connections are to
be used (CUNA/UNI and ISO/DIN
Standards). Follow the instructions
provided by the vehicle manufacturer
and/or the tow hitch manufacturer.
An electric brake (or electric winch)
should be supplied directly by the
battery through a cable with a cross
section of no less than 2.5 mm
2.
IMPORTANT Electric brakes or other
devices must be used with engine
running.
In addition to the electrical branches,
the vehicle's electric system can only
be connected to the supply cable for an
electric brake and to the cable for an
internal light, though not above 15
W. For connections use the preset
control unit with battery cable no less
than 2.5 mm
2.IMPORTANT The trailer tow hook
contributes to the length of the vehicle.
When installing on long wheelbase
versions, it is only possible to install
removable tow hooks because the total
vehicle length limit of 6 metres is
exceeded.
If no trailer is fitted, the hook must be
removed from the attachment base and
it must not exceed the vehicle's
original length.
IMPORTANT If you wish to leave the
tow hook fitted without towing a trailer,
it is advisable to contact a Fiat
Dealership for the relevant system
update operations because the tow
hook could be detected as an obstacle
by the central sensors.Installation diagram for
Van versions fig. 174
The tow hook structure must be
fastened in the points shown by the
symbol Ø using a total of 6 M10x1.25
screws and 4 M12 screws.
The internal back plates must be at
least 5 mm thick. MAX LOAD ON
BALL: 100/120 kg according to the
payload (see “Weights” table in the
“Technical data” section).
142)
To install a tow hook, the bumpers
must be trimmed as described in the
supplier's installation kit.
191

IMPORTANT
43) Keep your speed down when
snow chains are fitted; do not
exceed 50 km/h. Avoid potholes,
steps and pavements and avoid
driving for long distances on
roads not covered with snow to
prevent damaging the vehicle and
the roadbed.
PROLONGED
VEHICLE INACTIVITY
If the vehicle needs to be off the road
for longer than one month, the following
precautions must be taken:
❒park the vehicle indoors in a dry and,
if possible, well-ventilated place;
❒engage a gear;
❒check that the handbrake is not
engaged;
❒disconnect the negative battery
terminal; if the vehicle is equipped
with a battery disconnection function
(disconnector), see the description
of the procedure in the "Controls"
paragraph in the "Dashboard and
controls" section;
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds
available commercially;
❒sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glass;
❒slightly open the windows;❒cover the vehicle with a piece of
fabric or perforated plastic sheet. Do
not use compact plastic tarpaulins,
which prevent humidity from
evaporating from the surface of the
vehicle;
❒inflate tyres to +0.5 bar above the
standard specified pressure and
check it at intervals;
❒do not drain the engine cooling
system.
IMPORTANT If the vehicle is equipped
with an alarm system, switch off the
vehicle alarm with the remote control.
IMPORTANT After turning the ignition
key to STOP and having closed the
driver side door, wait at least one
minute before disconnecting the
electrical supply from the battery. When
reconnecting the electrical supply to
the battery, make sure that the ignition
key is in the STOP position and the
driver side door is closed.

151) No tools other than the crank
provided should be used with
the spare wheel lifting device; it
should be operated by hand only.
152) On versions equipped with
self-levelling air suspension, never
introduce the head or hands in
the wheel arch: the vehicle could
raise or lower automatically
depending on possible load or
temperature changes.
153) The device should only be
operated by hand, without using
any type of tool other than the
crank provided, like pneumatic or
electrical screwers.
154) The moving components of the
jack (screw and joints) can also
cause injuries: do not touch them.
If you come into contact with
lubricating grease, clean yourself
thoroughly.155) At the end of the operation of
raising/locking the spare wheel,
after having checked the correct
positioning of the wheel under the
platform (yellow notch inside the
window on the device), the
spanner must be extracted, taking
care not to turn it in the wrong
direction (as in fig. 190) to
facilitate the extraction of the
spanner itself, to prevent the
attachment device from being
released and the wheel assembly
not being securely retained.
156) Each time the spare wheel is
moved, check that it is correctly
positioned in its housing under
the platform. If it is not correctly
positioned, this could adversely
affect safety.
157) The spare wheel lifting device
is equipped with a clutch safety
system for its own protection; this
could activated if an excessive
load is applied on the
maneuvering screw.FIX&GO

IN AN EMERGENCY

USEFUL ADVICE FOR
EXTENDING THE LIFE OF
YOUR BATTERY
To avoid draining your battery and
make it last longer, observe the
following instructions:
❒when you park the vehicle, ensure
that the doors, tailgate and bonnet
are closed properly, to prevent any
roof lights from remaining on inside
the passenger's compartment;
❒switch off all roof lights inside the
vehicle: the vehicle is however
equipped with a system which
switches all internal lights off
automatically;
❒do not keep accessories (e.g. sound
system, hazard lights, etc.) switched
on for a long time when the engine
is not running;
❒before carrying out any operation on
the electrical system, disconnect the
negative battery cable through the
suitable terminal;
❒Completely tighten the battery
terminals.IMPORTANT After turning the ignition
key to STOP and having closed the
driver side door, wait at least one
minute before disconnecting the
electrical supply from the battery. When
reconnecting the electrical supply to
the battery, make sure that the ignition
key is in the STOP position and the
driver side door is closed.
IMPORTANT If the charge level remains
under 50% for a long time, the battery
is damaged by sulphation, reducing
its capacity and efficiency at start-up.
The battery is also more prone to the
risk of freezing (at temperatures as high
as -10°C).
Refer to the paragraph "Car inactivity"
in "Starting and driving" if the car is
left parked for a long time.If, after buying the vehicle, you want to
install electrical accessories which
require permanent electric supply
(alarm, etc.) or accessories that in any
case burden the electrical supply,
contact a Fiat Dealership, whose
qualified personnel, in addition
to suggesting the most suitable devices
from Lineaccessori Fiat, will evaluate
the overall electrical consumption,
checking whether the vehicle’s electrical
system is capable of withstanding the
load required, or whether it should
be integrated with a more powerful
battery.
Since some of these devices continue
to consume electricity even when
the engine is off, they gradually run
down the battery.
IMPORTANT If a tachograph is fitted, if
the vehicle is parked for a long period
of 5 days, it is advisable to disconnect
the negative battery terminal to
maintain its charge.
If the vehicle is equipped with a battery
disconnection function (disconnector),
see the description of the procedure
in the "Controls" paragraph in the
"Dashboard and controls" section.
