2005 Alfa Romeo 156 wiper blades

GETTING TO KNOW YOUR CAR52
When the rain sensor is reactivated, the
wiper performs at least one stroke, even if
the windscreen is dry, to indicate that reac-
tivation has occurred.
WARNINGIn case of failure of the right-
hand stroke or rain sensor, windscreen wiper
operation with the right-hand lever at (B)
shall take place in intermittent mode.
The rain sensor is located behind the inner
rear-view mirror in contact with the wind-
screen and inside the area cleaned by the
wiper and it controls an electronic control
unit which in turns controls the wiper motor.At each start, the rain sensor automatically
stabilises at a temperature of about 40°C
to eliminate any condensation from the con-
trol surface and prevent the formation of ice.
The rain sensor is able to detect and au-
tomatically adapt to the presence of the fol-
lowing particular conditions which require
different sensitivity:
– impurities on the control surface (salt,
dirt, etc.);
– streaks of water caused by worn wiper
blades;
– difference between day and night (the
human eye is more disturbed during the
night by the wet glass surface).Headlight washers (fig. 78)
(optional for versions/markets
where applicable)
These are operated when the sidelights
are on and the windscreen washer is
switched on.

DRIVING IN THE RAINRain and wet roads can be dangerous.
If the road is wet, the traction between
wheel and asphalt is greatly reduced, thus
increasing the stopping distance and de-
creasing road holding.
Here are few suggestions in the case of
rain:
– Reduce speed and keep further back
from the vehicle in front.
– If it is raining particularly heavily, visi-
bility is also reduced. In these cases, switch
on the dipped headlights even if it is still day-
light so you can be seen more easily.
– Do not drive through puddles at speed
and hold on tightly to the wheel if you do: a
puddle taken at high speed might cause you
to lose control of the car (“aquaplaning”).
– Position the ventilation controls for
demisting (see chapter “Getting to know
your car”), to prevent visibility from wors-
ening.
– Routinely check the conditions of the
windscreen wiper blades.
DRIVING IN THE FOG– If fog is very thick, avoid travelling
where possible. If travelling with mist,
ground fog or the possibility of fog banks:
– Drive at moderate speed.
– Also in the day turn on the dipped-beam
headlights, rear fog guards and front fog
lights. Do not use the main beam headlights.
WARNINGOn stretches of road with
good visibility, switch off your rear foglights;
the brightness of these lights could annoy
the people travelling in the cars behind.
– Remember that fog also involves wet
asphalt, thus greater difficulty in all types of
manoeuvres and longer stopping distances.
– Keep well away from the vehicle in
front.
– Where possible avoid sudden changes
in speed.
– Possibly avoid overtaking other vehicles.
– If the vehicle is forced to stop (faults,
impossibility to continue due to poor visi-
bility, etc.), firstly try to pull off the road.
Then turn on the hazard warning lights and,
if possible the dipped beam headlights. Ry-
thmically sound the horn if you note another
car coming.
MOUNTAIN DRIVING– When driving downhill, use the engine
braking by engaging a low gear, to prevent
the brakes from overheating.
– Never coast downhill with the engine off
or in neutral and especially not with the ig-
nition key removed.
– Drive at moderate speed and avoid “cut-
ting” corners.
– Remember that overtaking up hill is
slower and therefore requires a greater
length of clear road. If you are being over-
taken on a hill, move over to enable the
other vehicle to pass in safety.

CORRECT USE OF THE CAR

Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements and
avoid also to drive for long dis-
tances on roads not covered with
snow to prevent damaging the car
and the roadbed.
VEHICLE INACTIVITYIf the car is to be left inactive for long pe-
riods, the following precautions should be
noted:
– House the vehicle under cover in a dry
and possibly ventilated place.
– Engage a gear.
– Check that the handbrake is not en-
gaged.
– Clean and protect the painted parts us-
ing protective wax.
– Disconnect the negative terminal (–)
and check the battery charge. This check is
to be repeated every three months.
Recharge if the optical indicator shows a
dark colour without the central green area.
WARNINGWhere applicable, switch off
the electronic car alarm with the remote con-
trol.– Clean and protect the shiny metal parts
using special compounds readily available.
– Sprinkle talcum powder on the rubber
windscreen and rear window wiper blades
and lift them off the glass.
– Slightly open the windows.
– Cover the car with a cloth or perforated
plastic sheet. Do not use sheets of non-per-
forated plastic as they do not allow mois-
ture on the car body to evaporate.
– Inflate the tyres to 0.5 bar above the
normal specified pressure and check it at in-
tervals.
– If you don’t disconnect the battery from
the electric system, check its charge every
month and recharge it if the optical indica-
tor shows a dark colour without the central
green area.
– Do not drain the engine cooling system. Snow chains cannot be
fitted to the spare wheel
so, if a front (drive) tyre is
punctured and chains must be fit-
ted, the rear wheel should be fit-
ted to the front of the vehicle (in-
flate the tyres to the specified
pressure as soon as possible) and
the spare tyre should be fitted to
the rear. A snow chain can then be
safely fitted to the front wheel.

Proceed as follows:
– Raise the windscreen wiper arm and po-
sition the blade so that it forms an angle
of 90° with the arm.
– Press tab (B) of the coupling spring and
remove the blade to be replaced from the
arm (A).
– When the spring is released from the
curved top of the arm, move the blade to al-
low the arm to be withdrawn through the slot.
– Insert a new blade passing it through the
curved top of the arm (A) through the slot.
– Lift the blade to clamp tab (B) of the cou-
pling spring with the curved top of the arm.
– Lower the windscreen wiper arm.
WARNINGThe blades may differ ac-
cording to the versions. In any case, follow
the instructions provided in the packs avail-
able as spares from Alfa Romeo Authorized
Services. Changing the windscreen wiper
blade (fig. 27)
WARNINGThe blade on driver’s side
is fitted with a spoiler that improves adhe-
sion between the blade and the windscreen.
To prevent improper fitting, before changing
the blade, check the spoiler direction of the
blade to be replaced, then fit the new blade
following the same spoiler direction.

WINDSCREEN/REAR
SCREEN WIPERSBLADESPeriodically clean the rubber part using spe-
cial products TUTELA PROFESSIONAL
SC 35is recommended.
If the rubber blades are bent or worn they
should be replaced. In any case they should
be changed once a year.
A few simple notions can reduce the pos-
sibility of damage to the blades:
– If the temperature falls below zero,
make sure that ice has not frozen the rub-
ber against the glass. If necessary, thaw us-
ing an antifreeze product.
– Remove any snow from the glass: in ad-
dition to protecting the blades, this prevents
effort on the motor and overheating.
– Do not operate the windscreen and rear
window wipers on dry glass.
Driving with worn wiper
blades is a serious hazard,
because visibility is reduced in bad
weather.
