2007 Alfa Romeo 156 fuel pressure

GETTING TO KNOW YOUR CAR

FUEL CAP
(fig. 176)
The fuel flap is released from inside the
car, raising the front part of the lever (A).
The fuel cap (A-fig. 177) has a catch
to prevent misplacing it (B) that fastens it
to the flap (C).
WARNINGThe fuel tank is sealed her-
metically and pressure may build up inside.
Any noise of rushing air when the cap is re-
moved is perfectly normal.

In case of need, replace
the fuel cap only with an
original one; otherwise,
the efficiency of the petrol vapour
recovery system could be badly af-
fected.
EMERGENCY FLAP OPENING
DEVICEIf the lever (A-fig. 176) fails to work,
it is still possible to open the flap by pulling
the cord (A-fig. 178) on the right-hand
side of the luggage compartment.fig. 178

WARNINGFor your safety, make sure
that the fuelling pump nozzle is inserted cor-
rectly into the housing, before starting the
engine.
Do not get near the fuel
filler with naked flames or
lit cigarettes: danger of fire. Also
avoid going too near the filler with
the face to avoid inhaling harmful
vapours.
WARNING

CORRECT USE OF THE CAR
196
Tyres
Tyres should be checked at least every four
4 weeks: if the pressure is too low, fuel con-
sumption increases as the resistance to the
rolling movement of the tyre is higher. In
this state, tyre wear is increased
and vehicle handling suffers which will af-
fect safety.
Unnecessary loads
Do not travel with too much luggage stowed
in the boot. The weight of the vehicle (es-
pecially when driving in town) and its trim
greatly affects consumption and stability.
Luggage/ski rack
Remove luggage or ski racks from the roof
of the vehicle as soon as they are no longer
needed. These accessories reduce the aero-
dynamic penetration of the vehicle and will
increase consumption. When transporting
particularly large objects, use a trailer where
possible.Electrical devices
Use the electric devices for the necessary
time only. The heated rear window, supple-
mentary lights, windscreen wipers, heating
system blower require large amounts of en-
ergy and, increasing the request for power
also increases fuel consumption (up to
+25% when driving in built-up areas).
Air conditioner
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
vehicle permits it, use the air vents where
possible.
Spoilers
The use of aerodynamic optional extras
which are not certified for the specific use
on the vehicle, may reduce the aerodynamic
penetration of the vehicle and increase con-
sumption.
STYLE OF DRIVINGStarting
Do not warm the engine when the vehicle
is stationary or at high or low revs: in this
way the engine will warm up gradually in-
creasing consumption and emissions. You
should drive off slowly straight away avoid-
ing high revs so that the engine will warm
up more quickly.
Unnecessary actions
Avoid revving the engine when stopped at
traffic lights or before switching off the en-
gine and avoid doubling the clutch as these
actions have no purpose on modern vehicles
and serve only to increase consumption and
pollution.
Gear selection
As soon as the traffic and road conditions
allow it, shift to a higher gear. Using a lower
gear to liven up acceleration greatly in-
creases consumption. In the same way, im-
proper use of the higher gears will increase
consumption, emissions and wear and tear
on the engine.

ADDITIONAL
OPERATIONSEvery 1000 kmor before long journeys
check and if necessary top up:
– engine coolant level
– brake fluid/hydraulic clutch control flu-
id level
– power steering fluid level
– windscreen washer and headlamp wash-
er fluid level
– tyre pressure and conditions.
Every 3000 kmcheck the level of the
engine oil and top up if necessary.
You are recommended to use products of
the FL Selenia, designed and developed
expressly for Alfa Romeo cars (see the table
“Specifications of fluids and lubricants” in
the “Technical specifications” chapter).
ANNUAL INSPECTION
PROGRAMMEAn annual inspection programme
has been established for cars thet
cover less than 20,000 km (e.g.
10,000 km). It consists of the fol-
lowing:
– Check tyre conditions/wear and adjust
pressure if required (including the compact
spare wheel)
– Check lighting system operation (head-
lights, direction indicators, hazard lights,
boot lights, passenger compartment lights,
glovebox light, warning lights of instrument
panel, etc.)
– Check windscreen and rear-screen
wiper/washer operation, adjust nozzles
– Check windscreen/rear-screen blade po-
sition/wear
– Check condition and wear of the front
brake pad
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication– Visually check the following: engine,
gearbox, transmission, piping (exhaust - fu-
el - brakes) rubber components (casings -
sleeves - bushings, etc..), brake and fuel
hoses
– Check battery charge condition
– Visually check the condition of the belts
and various controls
– Check and top up if necessary, the flu-
id levels (coolant, brake fluid, windscreen
washer fluid, battery, etc.)
– Change engine oil
– Replace engine oil filter
– Change pollen filter.
