2007 Alfa Romeo 166 light

107
The gas springs are cali-
brated to guarantee
correct operation with
loading specified by the manufac-
turer. Arbitrary additions to the
boot lid (spoiler etc.) may affect
its operation and safety.
EMERGENCY OPENING
The luggage compartment lock is re-
leased by a servocontrol when opening
the bonnet from inside or using the key.
However, it is always possible to open
the luggage compartment, even in case
of insufficient battery power: just rotate
the key wider and simultaneously press
the bonnet edge by the hand.
IMPORTANTApply a moderate pres-
sure only on the bonnet edge, immediate-
ly above the lock.
LIFTING AND CLOSING
Lifting the boot lid is made easier by the
action of the gas springs (B-fig. 138).When the boot is opened the light (C-
fig. 138) will come on. This light will
go out again when the boot is closed.
In order to close, lower the bonnet by
the handle (A-fig. 139) on the lining
and press next to the lock till it clicks into
the right position.
Leaving the boot open, the light goes out
automatically after a few minutes. To turn it
on again, open the boot and close it again.

SECURING THE LOAD
The loads carried may be blocked with
straps hooked to the special rings in the
boot corners (fig. 140). The rings also
serve to secure the luggage retaining net
(available on request c/o Alfa Romeo Au-
thorized Services).

678PGSm
Do not load the luggage
compartment above the
permitted maximum (see “Techni-
cal specifications”). Also make sure
that the objects contained in the
boot are well secured to prevent
them from being thrown forward
causing harm to the passengers in
the event of sharp braking.
WARNING
A heavy load that has not
been secured may cause
serious harm to passengers in the
event of an accident.
WARNINGIMPORTANT Travelling at night with
a load in the boot it is necessary to adjust
the height of the low beam headlights
(see next paragraph “Headlights” in this
chapter). For correct use of the aiming
device, also make sure that the load does
not exceed the values given in the same
paragraph.

To close:
– Lower the bonnet to approx. 20 cm.
from the engine bay, then let it drop. Try
lifting it to make sure that it is shut com-
pletely and not simply caught in the safe-
ty position.
If the bonnet does not close properly do
not push it down but open it again and
repeat the above procedure.HEADLIGHTS
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.
For safety reasons the
bonnet shall always be
perfectly closed when travelling.
Always check for proper bonnet
locking. If the bonnet is left inad-
vertently open, stop the car im-
mediately and close the bonnet.
WARNING

111
GAS DISCHARGE HEADLIGHTS
(optional for versions/markets where
applicable)
Gas discharge headlights (xenon) work
with a voltaic arc, in an atmosphere satu-
rated with pressurised xenon gas, instead
of the incandescent filament.
The lighting produced is remarkably
higher than that of the conventional light
in both terms of the quality of the light
(lighter) and of the amplitude and posi-
tion of the lit area.
The advantages offered by better light-
ing are noted (due to less sight fatigue
and better orientation capability of the
driver, thus of travelling safety) especially
in bad weather, fog and/or insufficient
signs, because of the higher lighting
of the side beams which are normally
shaded.
The heavy increase of lighting in the
side beams considerably increases driving
safety because it allows the driver to bet-
ter see other users at the sides of the
road (pedestrians, cyclists and motorcy-
clists).Very high voltage is needed to trigger
the voltaic arc, after which the supply can
be at low voltage.
The headlights reach their maximum in-
tensity after about 15 seconds from
switching on.
The high luminosity produced by this
type of headlight calls for the use of an
automatic system to keep the headlight
beam aiming constant and prevent daz-
zling other vehicles when braking, accel-
erating and carrying loads.
The electromechanical system for auto-
matic constant beam aiming makes the
headlight aiming device superfluous.
Xenon lights are very long-lasting and
failure is unlikely.
If necessary, have the
system checked and any
repairs done only by Authorized Al-
fa Romeo Services.
WARNING

112
AIMING LOW BEAM
HEADLAMPS FOR
LEFT/RIGHT CIRCULATION
(only for versions with gas discharge
headlamps)
On cars fitted with gas discharge head-
lamps (xenon bulbs)(optional for ver-
sions/markets where applicable) with
high lighting power, when passing from a
country with right circulation to one with
left circulation or vice versa it is necessary
to change the aiming of the low beams,
to optimise lighting of the edge of the
road and avoid glaring vehicles met.
IMPORTANT Contact Alfa Romeo Au-
thorised Services to have low beam head-
lamps correctly adjusted.
BEAM AIMING
(excluding versions with gas discharge
headlights)
The adjustment of the headlights 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.
Contact Alfa Romeo Authorized Services
to have the headlights correctly adjusted.
When returning to the
country of origin, re-
member to change the low beam
aiming again.
WARNING
To have the position
checked and if neces-
sary adjusted, contact
Alfa Romeo Authorized Services.

EOBD SYSTEM
(optional for versions/
markets where applicable
)
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis of
the components of the car correlated with
emissions.
This system continuously monitors the
components of the vehicle related to e-
missions; it also indicates, when the
Uwarning light comes on on the instrument
panel, that the components in question
are in poor condition.
IMPORTANTAfter the problem has
been resolved, to completely check the
system, the Alfa Romeo Authorized Ser-
vice Station must carry out tests on a test
bench and, if necessary, road tests that
could be long.If, when the ignition key
is turned to MAR, the
Uwarning light does
not come on or if, when driving, it
lights up and emits a fixed light
or a flashing one, contact an Alfa
Romeo Authorized Service Station
as soon as possible. Warning
light
Uoperation can be checked
by means of special equipment
by traffic agents. Always comply
with the traffic regulations in
force in the country where you
are travelling.
The objective is the following:
– to keep under control the efficiency of
the system;
– to warn when a fault causes emission
levels to increase;
– to indicate the need to replace the
deteriorated components.
The system also has a diagnostic con-
nector that can be interfaced with appro-
priate tools, which makes it possible to
read the error codes stored in the control
unit, together with a series of specific pa-
rameters for engine operation and diag-
nosis. This check can also be carried out
by the traffic police.

114 ABS
The car is fitted with an ABS system
which prevents wheel lock when braking,
better exploits wheel grip and keeps the
vehicle controllable within the limits of
the available grip also during emergency
braking.
The driver can feel that the ABS is oper-
ational by a light pulsing of the brake
pedal, accompanied by noise.
This should not be interpreted as malfunc-
tioning of the brakes, but it is the signal to
the driver that the ABS system is working:
it is the warning that the car is travelling at
the limit of grip and that it is therefore nec-
essary to adapt the speed to the type of
road on which you are travelling.
The ABS system is an additional part of
the basic braking system; in the event of
a fault it is disabled, leaving the braking
system in the same conditions as a car
without ABS.In the event of a failure, though being
unable to rely on the antilock effect,
there is absolutely no adverse effect on
vehicle braking performance in terms of
braking capacity.
If you have never used a car with ABS
before, you are advised to learn how to
use it with a few preliminary trials on a
slippery surface, naturally under safety
conditions and fully adhering to the High-
way Code of the country concerned. You
are also advised to carefully read the fol-
lowing information.
The advantage of the ABS compared
with the conventional system is that it
makes it possible to maintain maximum
vehicle handling performance also in the
case of hard braking under grip limit con-
ditions, avoiding wheel lock.
Do not however expect the braking dis-
tance always to be reduced with the ABS
system: for example, on soft surfaces
such as gravel or fresh snow on slippery
surfaces, the distance might increase.In order to be able to exploit as far as
possible the possibility of the antilock
system in the case of need, it is wise to
follow a few pieces of advice.
The ABS exploits the
available grip in full, but
it cannot increase it; therefore cau-
tion is required on slippery surfac-
es, without running un-necessary
risks.
WARNING

115
Braking on corners always requires the
utmost caution, even with the help of the
ABS.
The most important piece of advice
however, is the following:WARNINGCars fitted with ABS must
only be fitted with wheel rims, tyres and
brake linings of the type and brand ap-
proved by the Manufacturer.
The braking system is completed by the
EBD (Electronic Brake Distributor) which
distributes the braking action through the
ABS control unit and sensors.
Following these instructions you will be
in a condition to obtain peak braking per-
formance at all times.
If the ABS cuts in, it
means that the grip limit
between the tyres and the road
surface has been reached: it is nec-
essary to slow down and adapt
driving to the grip available.
WARNING
In the event of a system
fault, with lighting up of
the
>warning light, have the ve-
hicle checked immediately by Au-
thorized Alfa Romeo Services, driv-
ing slowly to be able to regain full
system performance.
WARNING
When the ABS cuts in and
you feel the pedal pulse,
do not reduce the pressure, but
keep the brake pedal firmly
pressed with no fear; this way you
will stop in the shortest space pos-
sible, compatibly with the condi-
tions of the road surface.
WARNING
The car is fitted with an
electronic brake distrib-
utor (EBD). If the
>andxwarn-
ing lights come on at the same time
when the engine is running, there
is an EBD system fault; in this case,
violent braking may lock the rear
wheels too early, with the possibil-
ity of skidding. Drive extremely
carefully to the nearest Authorized
Alfa Romeo Services to have the
system checked over.
