2008 FIAT CROMA fuel

When stopping the car with a gear high-
er than 1st gear, transmission will set au-
tomatically at 1st gear.
When stopping the car under poor grip
conditions (snow, ice), at next starting the
transmission control unit could engage a
gear higher than 1st gear to prevent wheel
slipping. This shall not be considered as a
fault
IMPORTANT: in the event of excessive
oil temperatures (see section “Warning
lights and messages”), the electronic con-
trol intervenes excluding sequential mode
and activating automatic mode in order to
safeguard transmission life. Sequential
mode will be resumed as soon as regular
operating temperatures are restored.AUTOMATIC MODE
D can be selected from sequential mode
under whatever driving condition.
When passing from sequential mode to D,
the gear to engage is selected by trans-
mission control unit according to engine
rpm and speed (accelerator pedal posi-
tion).
Low engine power demand will result in
long gears engagement and reduced fuel
consumption. Increasing speed by press-
ing the accelerator will automatically en-
gage short gears that will result in im-
proved performance as to pickup and ac-
celeration: in this case fuel consumption
will increase.
For speedy pickup:
❒press the accelerator pedal flat-out,
the kick-down device will cut in to ob-
tain max. performance in terms of
pickup and acceleration. In this case fu-
el consumption will obviously increase.
IMPORTANT When driving under poor
grip conditions (snow, ice, etc.) avoid to
engage the kick-down device. SEQUENTIAL MODE
In sequential mode, the electronic auto-
matic transmission works like a fixed gear
sequential gearbox.
From position D move the gear lever left-
wards:
❒move gear lever to +: to upshift;
❒move gear lever to –: to downshift.
Gears are displayed by digits on the in-
strument panel. Non-stop monitoring car-
ried out by transmission control unit ex-
cludes whatever possibility of error.
Downshifting (or upshifting) is only pos-
sible if engine rpm enables it.
In sequential mode, electronic transmis-
sion control can however intervene in self-
adapting mode by shifting gears automat-
ically when engine rpm exceeds or falls be-
low the admitted rpm limit.

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.

GENERAL INSTRUCTIONS
Wheel changing and correct use of the
jack and space-saver spare wheel call for
some precautions as listed below.
BUMP STARTING
Never bump start the engine (by pushing,
towing, or coasting downhill) as this could
cause fuel to flow into the catalytic ex-
haust system and damage it beyond repair.
Remember that the brake booster and the
power steering system are not operating
until the engine is started, a greater effort
will therefore be required to press the
brake pedal or to turn the steering wheel.
Alert other drivers that the
car is stationary in compli-
ance with local regulations: hazard
warning lights, warning triangle etc.
Any passengers on board should leave
the car, especially if it is heavily laden.
Passengers should stay away from on-
coming traffic while the wheel is be-
ing changed on. If the wheel is being
changed on a steep or badly surfaced
road, place the wedges or other suit-
able material under the wheel to stop
the car.
WARNING
The space-saver spare wheel
is specific to your car, do not
use it on other models, or use the
spare wheel of other models on your
car. The space-saver spare wheel
shall only be used in an emergency.
It shall only be used for the distance
necessary to reach a service point and
the car speed shall not exceed 80
Km/h. The spare wheel has an orange
sticker that summarises the main cau-
tions for use and limitations. The
sticker should never be removed or
covered.
Never fit a wheel cap on a space-
saver spare wheel. The sticker gives
the following information in four lan-
guages: caution! For temporary use
only! 80 km/h max! Replace by nor-
mal wheel as soon as possible. Do not
cover this label.
