2006 FIAT CROMA fuel pressure

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.

❒brake fluid level;
❒windscreen washer fluid level;
❒tyre pressure and conditions;
❒light system operation (headlights, di-
rection indicators, hazard lights, etc.);
❒windscreen wiper/washer operation
and windscreen/rear window blade
position/wear;
Every 3,000 km check and top up if re-
quired: engine oil level.
You are recommended to use FL
Selenia, products, designed and pro-
duced specifically for Fiat cars (see table
“Capacities” in section “Technical speci-
fications”).
HEAVY-DUTY
Should prevailing use of the car be under
one of the following specially heavy con-
ditions:
❒trailer or caravan towing;
❒dusty roads;
❒short distances (less than 7-8 km) re-
peated and with external tempera-
tures below zero;
❒frequently idling engines or long dis-
tance low speed driving (e.g. door-to-
door deliveries) or in case of a long
term inactivity;
❒driving in the city;
carry out the following checks more fre-

CAR
MAINTENANCE
❒If a tyre is punctured, stop immediate-
ly and change it to avoid damage to the
tyre, the rim, suspensions and steering
system;
❒Tyres age even if they are not used
much. Cracks in the tread rubber are
a sign of ageing. In any case, if the tyres
have been on the car for over 6 years,
they should be checked by specialised
personnel, to see if they can still be
used. Also remember to check the
space-saver spare wheel;
❒In the case of replacement, always fit
new tyres, avoiding those of dubious
origin;
❒If a tyre is changed, also change the in-
flation valve;
❒To allow even wear between the front
and rear tyres, it is advisable to change
them over every 10-15 thousand kilo-
metres, keeping them on the same
side of the car so as to not reverse the
direction of rotation.
Remember that road holding
depends also on the correct
tyre inflating pressure.
WARNING
Do not cross switch the
tyres, moving them from the
right of the car to the left and vice
versa.
WARNING
If the pressure is too low the
tyre overheats and this can
cause it serious damage.
WARNING
Never submit alloy rims to
repainting treatments re-
quiring to use temperatures exceed-
ing 150°C since the mechanical prop-
erties of the wheels could be im-
paired.
WARNING
RUBBER HOSES
As far as the brake system and fuel rubber
hoses are concerned, carefully follow the
“Service schedule” in this section.
Indeed ozone, high temperatures and pro-
longed lack of fluid in the system may
cause hardening and cracking of the hoses,
with possible leaks. Careful control is
therefore necessary.
