EMERGENCY OPERATIONIf the electrical control device does not
work, the sunroof can be opened manually
as follows:
– apply leverage to the points indicated
by the arrows and remove the plate with
switch (D-fig. 159);
– use the outfit screwdriver or the special
wrench (B-fig. 160) supplied for the ver-
sions / market where provided, and located
in the object holder drawer, push on and turn
the sunroof control bushing (C-fig. 160)
clockwise to open it and anti-clockwise to
close it. WARNINGAt the end of the operation,
before removing the screwdriver or the
wrench, it is necessary to turn it by half a
turn in the direction opposite to that used,
until a click is felt.
LUGGAGE
COMPARTMENTThe boot lid can be opened from outside
the vehicle (pressing the button on the key)
and from inside the vehicle.
WARNINGIf the boot is not properly
shut, the warning light
´
will come on on
the instrument panel or (where applicable)
on the Infocenter display (together with rel-
evant message).

HEADLIGHTSLIGHT BEAM AIMINGWARNINGThe adjustment of the head-
lights is vital to your safety and comfort and
to that of other road users. The adjustment
of the headlights is also governed by precise
regulations. To guarantee both to yourself
and to the other drivers the best visibility
conditions when travelling with the head-
lights on, the vehicle must have its head-
lights properly adjusted.
Contact Alfa Romeo Authorized Services to
have the headlights correctly adjusted.
IMPORTANTOn the inside surface of
the headlight there could appear a slight
coat of fogging; this does not show a defect,
since it is a natural occurrence due to low
temperature and to the degree of humidity
in the air; it will soon disappear as soon as
the lights are turned on. The presence of
drops inside the headlight shows water seep-
age: refer to the Alfa Romeo Dealership.
ROOF RACK
PROVISIONThe car is set for mounting special roof
racks.
Roof racks, especially designed for this car,
must be fastened to pins (A-fig. 168) set
under the packing, as shown in the figure.
Strictly comply with the
regulations in force con-
cerning the maximum over-
all dimensions.

After a few kilometres,
check that the fastening
screws are firmly tightened.
WARNING
Distribute the load evenly
and when driving, bear in
mind the increased sensitivity to
side wind.

SOUND SYSTEM(where applicable)
The fixed sound system, with cassette
player (radio with cassette player) or CD
player with parametric sound equalizer (ra-
dio with CD player) has been designed to
suit the specific characteristics of the pas-
senger compartment, with a personalised
design that matches the style of the dash-
board. The sound system instructions for use
are described in the attached supplement.
SOUND SYSTEM
PRESETTING SYSTEM(for versions/markets where
applicable)
The car, if not delivered with sound sys-
tem, is fitted with a glove compartment
(fig. 172) on the instrument panel.
Sound system presetting system includes
the following:
– sound system power cables;
– front and rear speaker power cables;
– aerial power cable;
– sound system housing;
– aerial on car roof (where provided).The sound system shall be installed in the
proper housing occupied by the glove com-
partment that can be removed by pressing
the two retaining tabs in the glove com-
partment: here are the power cables.
If after buying the car you
want to install the sound
system, contact first Alfa
Romeo Authorised Services whose
qualified personnel, in addition to
suggesting the most suitable de-
vices, will evaluate the overall
electric absorption to safeguard the
battery. Excessive loadless ab-
sorption could damage the battery
and lose warranty.fig. 172

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.
