engine FIAT CROMA 2009 2.G Service Manual

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 lower air pene-
tration and adversely affect consumption
levels. When needing to carry particular-
ly voluminous objects, preferably use a
trailer.
Electric devices
Use electric devices only for the amount
of time needed. Rear heated window, ad-
ditional headlights, windscreen wipers and
heater fan need a considerable amount of
energy, therefore increasing the require-
ment of current increases fuel consump-
tion (up to +25% in the urban cycle).
Climate control
The air conditioner is an additional load
which greatly affects the engine leading to
higher consumption (on average up to
+20%). When the temperature outside
the car permits it, use the air vents where
possible.
Spoilers
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.DRIVING STYLE
Starting
Do not warm the engine with the car at
a standstill or at idle or high speed: under
these conditions the engine warms up
much more slowly, increasing electrical
consumption and emissions. It is therefore
advisable to move off immediately, slow-
ly, avoiding high speeds. This way the en-
gine will warm faster.
Unnecessary actions
Avoid accelerating when waiting at traffic
lights or before switching off the engine.
This and also double declutching is ab-
solutely pointless on modern cars and al-
so increase consumption and pollution.
Gear selection
As soon as the conditions of the traffic and
road allow, use a higher gear. Using a low
gear to obtain brilliant performance in-
creases consumption.
In the same way improper use of a high
gear increases consumption, emissions an
engine wear.CONTAINING
RUNNING COSTS
Here are some suggestions which may
help you to keep the running costs of your
car down and lower the amount of toxic
emissions released into the atmosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out
in accordance with the “Service schedule”.
Tyres
Check the pressure of the tyres routine-
ly at an interval of no more than 4 weeks:
if the pressure is too low, consumption
levels increase as resistance to rolling is
higher.
Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the car
(especially when driving in town) and its
trim greatly affects consumption and sta-
bility.

Traffic situations and road
conditions
Rather high consumption levels are tied to
situations with heavy traffic, for example
in queues with frequent use of the lower
gears or in cities with many traffic lights.
Also winding mountain roads and rough
road surfaces adversely affect consump-
tion.
Traffic hold-ups
During prolonged hold-ups (e.g.: level
crossings) the engine should be switched
off.TOWING TRAILERS
IMPORTANT NOTES
For towing caravans or trailers the car
must be fitted with a certified tow hook
and an adequate electric system. Installa-
tion should be carried out by specialised
personnel who release a special document
for circulation on the road.
Install any specific and/or additional rear-
view mirrors as specified by law.
Remember that when towing a trailer,
steep hills are harder to climb, the brak-
ing 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 the trailer exerts on the car
tow hook reduces by the same amount
the actual car loading capacity. 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 accessories and personal be-
longings. Top speed
Fuel consumption considerably increases
with speed. Avoid superfluous braking and
accelerating, which cost in terms of both
fuel and emissions.
Acceleration
Accelerating violently increasing the revs
will greatly affect consumption and emis-
sions: acceleration should be gradual and
should not exceed the maximum torque.
CONDITIONS OF USE
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 emission of harmful substances.

INSTALLING THE TOW HOOK
The towing device should be fastened to
the body by specialised personnel accord-
ing to any additional and/or integrative in-
formation supplied by the Manufacturer of
the device.
The towing device must meet current reg-
ulations with reference to 94/20/EC Di-
rective and subsequent amendments.
For any version the towing device used
must match the towable weight of the car
on which it is to be installed.
For the electric connection a unified con-
nector should be used which is generally
placed on a special bracket normally fas-
tened to the towing device, and a special
ECU for external trailer light control shall
be installed on the car.
For the electrical connection, 7 or 13 pin
12VDC connection is to be used (CU-
NA/UNI and ISO/DIN Standards). Follow
the instructions provided by the car man-
ufacturer and/or the tow hitch manufac-
turer.An electric brake should be supplied di-
rectly by the battery through a cable with
a cross section of no less than
2.5 mm
2.
IMPORTANT Electric brake or other de-
vice shall be used with running engine.
In addition to the electrical branches, the
car’s electric system can only be con-
nected to the supply cable for an electric
brake and to the cable for an internal light,
though not above 15W.
For connections use the preset control
unit with battery cable no less than 2.5
mm
2. Do not exceed the speed limits of the
country you are driving in. In any case do
not exceed 100 km/h.
It is recommended to use a proper tow-
ing stabiliser on the trailer drawbar.

❒clean and protect the painted parts us-
ing protective wax;
❒clean and protect the shiny metal parts
using special compounds readily avail-
able;
❒sprinkle talcum powder on the rubber
windscreen and rear window wiper
blades and lift them off the glass;
❒slightly open the windows;
❒cover the car with a cloth or perfo-
rated plastic sheet. Do not use sheets
of non-perforated plastic as they do

evaporate;
❒inflate tyres to +0,5 bar above the
normal specified pressure and check it
at intervals;
❒when the battery is not disconnected
from the electric system, if the vehicle
is equipped with a battery with an op-
tical indicator, control its charge sta-
tus every 30 days and if the optical in-
dicator shows a dark colour without
the central green zone, recharge it;
❒do not drain the engine cooling sys-
tem.
IMPORTANT Where relevant, switch off
the car alarm with the remote control.
CAR INACTIVITY
If the car is to be left inactive for longer
than a month, the following precautions
should be noted:
❒park the car in covered, dry and if pos-
sible well-ventilated premises;
❒engage a gear (position P with auto-
matic transmission);
❒check that the handbrake is not en-
gaged;
❒disconnect battery terminals (first dis-
connect the negative terminal);
❒if the vehicle is equipped with a bat-
tery with an optical indicator, control
its charge status. This check is to be
repeated every three months when
the car is left inactive. Recharge if the
optical indicator shows a dark colour
without the central green area;

❒flashing: indicates the possibility of
damage to the catalyst (see “EOBD

If the light flashes, it is necessary to release
the accelerator pedal to lower the speed
of the engine until the warning light stops
flashing; continue the journey at moder-
