2006 FIAT CROMA fuel

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 exhau-
st 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 com-
pliance with local regulations: hazard
warning lights, warning triangle etc.
Any passengers on board should lea-
ve the car, especially if it is heavily la-
den. Passengers should stay away
from oncoming traffic while the
wheel is being changed on. If the
wheel is being changed on a steep or
badly surfaced road, place the wed-
ges or other suitable 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 spa-
re 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 oran-
ge sticker that summarises the main
cautions for use and limitations. The
sticker should never be removed or
covered.
Never fit a wheel cap on a space-sa-
ver spare wheel. The sticker gives the
following information in four langua-
ges: caution! For temporary use only!
80 km/h max! Replace by normal
wheel as soon as possible. Do not co-
ver this label.
