brake light Alfa Romeo 166 2007 Owner handbook (in English)

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.
WARNING

116
BRAKE ASSIST (Brake assist in
an emergency)
This system, that cannot be cut out, rec-
ognizes emergency braking on the
ground of the brake pedal operation
speed and allows to speed up the braking
action.
On versions fitted with VDC system,
Brake Assist is deactivated in the event of
VDC system failure (indicated by the
switching on of the relevant warning
light).
The turning on of the>
warning light with the
engine running normally indicates
an ABS system fault. In this case
the braking system preserves its
effectiveness, without however
making use of the antilock device.
Under these circumstances, the EBD
system may fail to give top perfor-
mance. In this case, too, you are
recommended to contact Author-
ized Alfa Romeo Services immedi-
ately driving in such a way as to
avoid abrupt braking, to have the
system checked.
WARNING
If the xlow brake fluid
level warning light comes
on, stop the car immediately and
contact the nearest Authorized Al-
fa Romeo Services. Indeed, any
leak of fluid from the hydraulic
system compromises the effective-
ness of both the conventional
brake system and the system with
antilock system.
WARNING

134
In addition to the notes
and specifications given
below we recommend
that, during the initial period, y-
ou do not drive to full vehicle
performance (for example exces-
sive acceleration, long journeys
at top speed, hard braking etc.).
STARTING
THE ENGINE
IMPORTANT The car is fitted with an
electronic engine lock device. if the en-
gine fails to start see “The Alfa Romeo
CODE system”.The ignition switch is fitted with a safety
device which obliges the driver to return
the ignition key to the STOPposition be-
fore repeating the starting operation if
the engine does not start immediately.
Similarly, when the engine is running,
the device prevents the key being moved
fromMARto the AVV position.
PROCEDURE FOR PETROL
ENGINES
With cold engine:
1) Engage the handbrake.
2) Ensure that the systems and electri-
cal devices, especially if they absorb high
quantities of energy (e.g. heated rear
windscreen), are switched off.
3) Set the gearshift lever to neutral and
fully depress the clutch without pressing
the accelerator.
4) Turn the ignition key to the AVV posi-
tion releasing it as soon as the engine starts.
Never leave the ignition
key in the MAR position
when the engine is
switched off.
5) If the engine does not start immedi-
ately, return the key to the STOPposi-
tion and repeat the operation
With hot engine:
1) Engage the handbrake.
2) Ensure that the systems and electri-
cal devices, especially if they absorb high
quantities of energy (e.g. heated rear
windscreen), are switched off.
3) Set the gearshift lever to neutral and
fully depress the clutch without pressing
the accelerator.
4) Turn the ignition key to the AVV posi-
tion releasing it as soon as the engine starts.
5) If the engine does not start immedi-
ately, return the key to the STOPposition
and repeat the procedure, slightly pressing
the accelerator pedal without pumping it.
Running the engine in
confined areas is ex-
tremely dangerous. The engine
consumes oxygen and produces
carbon monoxide which is a highly
toxic and lethal gas.
WARNING

135
IMPORTANT If it is difficult to start the
engine do not insist with extended attempts
which may damage the catalyzer but con-
tact Alfa Romeo Authorized Services.
PROCEDURE FOR DIESEL
VERSIONS
1) Engage the handbrake.
2) Set the gearshift lever to neutral and
fully depress the clutch without pressing
the accelerator.
3) Turn the ignition key to the MAR
position. the
mwarning light on the in-
strument cluster will turn on.
4) Wait for the
mwarning light to go
off, which will depend on how warm the
engine is. If the engine is very warm the
turning on of the warning light may be so
fast as to go by unobserved.
5) Turn the ignition key to AVV as
soon as the
mwarning light goes off.
Waiting too long would make the glow
plug heating work pointless.IMPORTANT The electric devices that
absorb much energy (air conditioner,
rearscreen heating, etc.) are disengaged
automatically during engine starting.
If the engine does not start at the first
attempt, move the ignition key back to
theSTOPposition before repeating s-
tarting.
If starting is difficult (with the Alfa
Romeo CODE system efficient), do not in-
sist with prolonged attempts.
Only use an auxiliary battery if it is not-
ed that the cause is due to low charge of
vehicle’s battery. Never use a battery
charger to start the engine (see ”If the
battery is flat” in the chapter “In an e-
mergency”).
WARMING THE ENGINE
– Drive off slowly, at medium revs
without accelerating abruptly.
– Do not drive at full performance for
the initial kilometres of the journey. Wait
until the engine coolant temperature is
between 50 and 60°C.
SWITCHING OFF
– Release the accelerator pedal and
wait until the engine reaches idle speed.
– Turn the ignition key to the STOP
position and switch off the engine.
IMPORTANT After a hard journey, it
is advisable to allow the engine to “get
its breath back” before switching off, run-
ning it at idle speed to allow the tempera-
ture in the engine compartment to cool
down. For versions/markets
where applicable the
warning light m flashes
for about 30 seconds after start-
ing the engine meaning that
there is a fault to the glow plug
warming system, in which case,
contact Alfa Romeo Authorized
Services.

137
– Check the operation of the horn.
– Check the operation and degree of
wear of the windscreen wipers.
– Check the operation of the external
lights and if necessary, clean the light
units.
– Above all when driving at night,
check the alignment of headlight beams
before starting off.
– Check that no oil or other liquid is
leaking out under the car.
– Ensure that luggage is stowed away
correctly.
– Ensure that, in addition to yourself,
all passengers have fastened their seat
belts.
– Ensure that the handbrake is re-
leased and that the warning lights on the
instrument panel do not indicate a mal-
function. To avoid accidental movements
of the car, disengage the handbrake
keeping the brake pedal pressed.
The following should also be noted:
– Long distances should be tackled
when in good health and should where
possible be programmed, especially when
the roads are busy.– A light meal containing easily assimil-
able foods will help keep reflexes ready
and aid concentration for a safe journey.– Use the direction indicators when
changing direction.
– Switch on the external lights at sun-
set.
– Keep a safe distance from the vehicle
in front. A “safe” distance will vary ac-
cording to the speed of the vehicle,
weather conditions and road-traffic condi-
tions.
– Never drive with one hand resting on
the gear lever. The involuntary movement
of the gear lever which this causes, even
if slight, will cause avoidable wear to the
internal elements of the gearbox.
– Never drive with the gearbox in neu-
tral.
– Do not drive with your foot resting on
the clutch pedal as this habit leads to
rapid wearing of the clutch.
– Do not drive for long periods without
a break. During a break get out of the ve-
hicle and move around a bit to shake off
drowsiness.
– Ensure that the air in the vehicle is
changed constantly using the many possi-
bilities offered by the heating-ventilation
and climate control system.
WHEN TRAVELLING
– Driving with care also means being
able to predict the actions of other road
users, respecting the speed limits and oc-
cupying the near-side lane on motorways.
Driving under the influ-
ence of alcohol, drugs
and/or some medicines is highly
dangerous.
Never drive when drunk or under
the effect of drugs or medicines.
WARNING

138
PARKING
When the vehicle is parked, proceed as
follows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if parking the car
uphill or reverse if parking the car on a s-
loping road. On cars with automatic gear-
box set the gear lever to P.
– Turn the front wheels so that the vehi-
cle will immediately come to a halt if the
handbrake slips.
NIGHT DRIVING
Night driving involves a greater degree
of concentration, both physical and ner-
vous. Some suggestions concerning night
driving follow:
– Drive with particular care, reducing
speed if necessary especially on unlit
roads.
– Maintain a greater distance from the
vehicle in front than during the day as it
is more difficult to judge the speed of a
vehicle when only the lights can be seen.
– If you become drowsy stop the car
and rest. continuing the journey when
sleepy is dangerous for yourself and for
others.
–Ensure that the headlights are correct-
ly aligned: if they are too low visibility is
reduced and if they are too high they
may cause disturbance to other users.
– use the main-beam outside built-up
areas and only when you are certain that
other drivers are not disturbed by their
use.
– When meeting vehicles coming in the
opposite direction, switch off the main-
beam and drive with the dipped-beam
headlights on.
– Keep the headlights and light units
clean at all times. – Do not coast the vehicle down hill
with the engine switched off as this elimi-
nates the engine braking effect thus re-
quiring a greater effort on the brake ped-
al, on the power steering and consider-
ably more effort on the steering wheel.
– If it is necessary to stop the vehicle
following a malfunction, park off the
road, switch on the hazard warning lights
and set up the warning triangle to alert
other road users of the presence of your
vehicle. At all times comply with the cur-
rent road traffic regulations.To avoid useless con-
sumption of power and
possible draining of the
battery, never leave the ignition
key in the MAR position when
the engine is not running.Ensure that both yourself
and your passengers are
wearing their seat belts. Travelling
without seat belts greatly in-
creases the risks of serious injury
or even death in the event of an
accident.
WARNING
Never leave children un-
attended in the vehicle.
Always remove the key from the
ignition when leaving the vehicle
and take it with you.
WARNING

139
DRIVING UNDER ADVERSE
WEATHER CONDITIONS
Rain and fog can be extremely danger-
ous if the style of driving is not adapted
to suit these conditions. Some sugges-
tions are given below:
– if the road is wet, the friction be-
tween wheel and asphalt is greatly re-
duced thus increasing the stopping dis-
tance and decreasing road holding when
cornering.
Reduce speed and keep further back
from the vehicle in front.
– Heavy rain and fog reduce visibility.
Headlights should be switched on as the
road traffic laws and common sense dic-
tate, above all to render yourself visible
to others.
– Do not drive over puddles or flooded
roads at high speed as the aquaplaning
phenomenon may cause you to loose
control over the vehicle.
– If visibility is already reduced prevent
it from worsening by ensuring that the
windows do not steam up. Use the heat-
ing-ventilation controls as indicated in the
chapter “Know your vehicle”.– Check the condition of the windscreen
wiper blades.
– If fog is very thick avoid travelling
where possible. If travelling cannot be
avoided drive with extreme care and
moderate your speed. Avoid overtaking.
– If the vehicle is forced to stop owing
to a malfunction or zero visibility condi-
tions, pull off the road, switch on the haz-
ard warning lights and if possible, the
dipped-beam headlights.
MOUNTAIN DRIVING
Mountain driving requires a greater de-
gree of concentration. Some practical
hints follow:
– Before driving off check the level of
fluids (engine oil, brakes, coolant) and
the state of the tyres.
– When travelling down hill use the en-
gine braking by engaging lower gears to
prevent the brakes from overheating.
– Never coast downhill with the engine
off or in neutral and especially not with
the ignition key removed.
– Drive at a moderate speed and avoid
cutting corners.– Remember that overtaking uphill is
slower and therefore requires a greater
length of clear road. If you are being
overtaken on a hill move over to enable
the other vehicle to pass in safety.
WINTER DRIVING
If the temperature falls below 0°C or in
the presence of snow or ice the following
recommendations should be followed:
– Before driving off check that the
windscreen wipers are not frozen to the
windscreen.
– Remove the snow from the air intake
(grille) at the base of the windscreen.
– Do not stop long on deep snow with
the engine running: the snow might di-
vert the exhaust gas carbon monoxide in-
to the passenger compartment.
– Ensure that brakes and tyres are in
perfect working order.
–Ensure that the detergent liquid locat-
ed in the windscreen/headlight washers
has been topped up with anti-freeze and
anti-scale additives.
– Use engine braking where possible
and avoid abrupt braking.

140
– During cold weather even apparently
dry roads may be covered with occasion-
al patches of ice. Pay great attention
therefore when driving on roads which
are in the shade, or where rocks or trees
line the road and on which ice may per-
sist.
IMPORTANT To avoid damaging
tyres do not drive on bare patches of as-
phalt with snow chains fitted to the vehi-
cle. In extreme cases proceed slowly and
remove the chains as soon as possible.
When driving on snow with snow chains
fitted, it might be helpful to turn off the
ASR function of the VDC system (if pre-
sent): in fact, in these conditions, skid-
ding of the driving wheels when moving
off makes it possible to obtain higher
traction.
BRAKES
An efficient braking system is vital to
the safety of the vehicle and its passen-
gers.
To use the brakes correctly and to im-
prove their efficiency and limit wear the
following recommendations should be fol-
lowed:– Do not drive with your foot resting on
the brake pedal.
– Ensure that the brake pedal is not
blocked by the mat or other objects.
– Check the efficiency of the braking
system especially before long journeys.
– Check the handbrake and brake fluid
minimum level warning light
xon the
instrument panel. if the
xwarning light
comes on and stays on when the vehicle
is travelling check that the handbrake is
not engaged. If it is not, stop the vehicle
immediately and check the level of the
brake fluid. If the level is low the anom-
aly affecting the circuit should be rectified
immediately. If the
dwarning light
comes on when the brake pedal is
pressed, this means that the front brake
pads have reached the minimum permit-
ted thickness. Have them replaced as
soon as possible by Alfa Romeo Autho-
rized Services.
– The brake fluid is hygroscopic (i.e. it
absorbs humidity). To prevent the onset
of braking anomalies it should therefore
be replaced every two years regardless of
the kilometres travelled.
SERVO BRAKE
The vehicle is equipped with a servo-
braking system (active only when the en-
gine is running). When the engine is sta-
tionary a greater effort is required to de-
press the brake pedal in order to obtain
the same braking effect.
ANTI WHEEL-LOCK SYSTEM
(ABS)
The vehicle is equipped with an ABS sys-
tem with electronic braking device (EBD),
the following should be heeded:
– A slight pulsing may be felt on the
brake pedal caused by the intervention of
the ABS system.
– The performance of the system, in
terms of active safety, should not induce
the driver to take unnecessary and unjus-
tified risks.
– The conduct of the driver must always
reflect weather, road and traffic condi-
tions.
– Deceleration always depends on the
degree of grip between the tyres and the
road surface. Obviously road holding is

141
greatly reduced when there is ice or snow
on the road. Under these conditions the
stopping distance is increased despite the
use of the ABS system.VDC SYSTEM (VEHICLE
DYNAMICS CONTROL):
The VDC is an electronic vehicle stability
control system which, acting on the torque
and braking the wheels in a differentiated
manner, helps to bring the car back to the
correct course in the event of loss of grip.
When the sensors detect the conditions
that would lead to skidding, the VDC sys-
tem intervenes on the engine and on the
brakes producing a stabilising torque.
BRAKE ASSIST (Brake assist in
an emergency)
This system, that cannot be cut out, rec-
ognizes emergency braking on the
ground of the brake pedal operation
speed and allows to speed up the braking
action.
On versions fitted with VDC system, Brake
Assist is deactivated in the event of VDC
system failure (indicated by the switching
on of the relevant warning light).
The ABS system does not
dispense the driver from
driving carefully, especially when
the road is icy, snowed over or
wet.
WARNING
The car is fitted with an
electronic braking device
(EBD). if the
>andxwarning
lights turn on at the same time, this
means that there is an EBD system
fault; in this case violent braking
may be accompanied by early rear
wheel locking, with the possibility
of skidding. Drive the car extremely
carefully to the nearest Authorized
Alfa Romeo workshop to have the
system checked.
WARNING
The turning on of only
the
>warning light
with the engine running normally
indicates a fault to the ABS system
only. In this case the braking sys-
tem is still efficient, though with-
out the aid of the anti-lock device.
Under these conditions perfor-
mance of the EBD system may be
reduced. In this case too, you are
advised to go immediately to the
nearest Authorized Alfa Romeo
workshop, driving in such a way
as to avoid sharp braking, to have
the system checked over.
WARNING
The system performance
levels, in terms of active
safety, should not induce the dri-
ver to run pointless and unjustified
risks. Driving conduct should al-
ways be suited to the conditions of
the road surface, vision and traf-
fic. The responsibility for road
safety is always and anyway the
vehicle driver’s concern.
WARNING

153
Apart from the electrical branches taken
off for the obligatory signalling devices,
the vehicle’s electrical system can only be
connected to the supply cable for an elec-
tric brake and to the cable for internal
light, though not above 15W, in the trailer.
The electric brake must be directly sup-
plied by the battery through a cable with
a cross-section of over 2.5 mm
2.
INSTALLING TOW HOOK
(fig. 3)
The chart shows the attachment points
for fixing the tow hook to the body.
These points must not be changed irre-
spective of the shape and size of the
hook. For mechanical connection the fol-
lowing must be used:
– “ISO 50” 2nd category ball hook
(CUNA Table NC 138-40)
– 2nd category ball eyelet model “CU-
NA 502” (CUNA Table NC 438-40)
The tow hook structure must be fas-
tened in the points shown by the symbol
Øwith a total of 12 M10 screws.
The inner plate (1) should be at least 4
mm thick.
The side plates (2) should be at least 5
mm thick.
The fastening points (3) must be fitted
with a spacer with a 25 mm diameter
and 6 mm thickness.IMPORTANTIt is compulsory to fas-
ten a label of suitable size and material
(clearly visible) at the height of the hook
ball with the wording:
MAX. LOAD ON BALL 60 kg.
ELECTRICAL CONNECTIONS
The attachment for the trailer wiring
connections are to be applied to the tow
hook support in the most suitable posi-
tion.
For the electrical connections a 13 pole,
12V connection must be used.
For vehicle-trailer electrical connections
contact Authorized Alfa Romeo Services.Do not connect any
trailer services (fan,
fridge, etc.) to the vehi-
cle’s electrical system.
After assembly, the fas-
tening screw holes
should be sealed to prevent the in-
filtration of exhaust gas.
WARNING
