2006 Alfa Romeo 166 wheel size

50 FRONT AND SIDE
AIR BAGS
The car is fitted with front Air bags for
the driver (fig. 61) and front passenger
(fig. 62), side bags (fig. 63) and
front window bags.
FRONT AIR BAGS
Description and operation
The front Air bag (driver’s and passen-
ger’s) is a safety device that comes into
action in the event of a head-on collision.It is formed of an instantly-inflating
cushion contained in a special recess:
– in the centre of the steering wheel for
the driver,
– in the dashboard with a larger-sized
cushion for the passenger.

The action of the ASR system is particu-
larly helpful under the following condi-
tions:
– Skidding of the inner wheel on a
bend, due to the effect of the dynamic
changes of the load or over-accelerating.
– Excessive power transmitted to the
wheels, also in relation to the conditions
of the road surface.
– Acceleration on slippery, snowy or icy
surfaces.
– In the case of loss of grip on a wet
surface (aquaplaning).ASR FUNCTION (ANTISLIP
REGULATION): GENERAL
The ASR system integrates the VDC sys-
tem controlling the vehicle drive and com-
ing into operation automatically each
time one or both driving wheels skid.
Two different control systems are acti-
vated, depending on the skidding condi-
tions:
– If skidding concerns both driving
wheels, because it is caused by the exces-
sive power transmitted, the ASR system
cuts in reducing the power transmitted by
the engine.
– If skidding concerns only one driving
wheel, the ASR system cuts in automati-
cally braking the skidding wheel, with an
effect similar to that of a self-locking dif-
ferential.
For the VDC, ASR and
ABS systems to work
correctly, the tyres must be of the
same brand and type on all
wheels, in perfect conditions and
above all of the specified type,
brand and size.
WARNING

147
WINTER TYRES
These tyres are specially designed for
driving on snow and ice, to be fitted in re-
placement of those fitted on the car.
Use winter tyres of the same size as the
normal tyres provided on the car.
Alfa Romeo Authorised Services will be
pleased to advise you on the choice of
the car most suited to the use the Cus-
tomer intends to make of it.
For the type of tyre to be used, inflation
pressures and the specifications of winter
tyres, follow the instructions given in the
“Technical Specifications” chapter.
The winter features of these tyres are
reduced considerably when the tread
depth is below 4 mm. In this case, they
should be replaced.
Due to the winter features, under nor-
mal conditions of use or on long motor-
way journeys, the performance of these
tyres is lower than that of normal tyres.
It is necessary therefore to limit their
use to the purposes for which they are
certified.WARNINGWhen winter tyres are
used with a maximum speed index below
the one that can be reached by the vehi-
cle (increased by 5%), place a notice in
the passenger compartment, plainly in
the driver’s view which states the maxi-
mum permissible speed of the winter
tyres (as per CE Directive).
Fit the same type of tyre on all four
wheels (brand and profile) to ensure
higher driving safety when braking and
good handling.
Remember that it is inappropriate to
change the direction of rotation of tyres.
SNOW CHAINS
Use of snow chains should be in compli-
ance with local regulations. Snow chains
should only be applied to the drive
wheels (front). The sport connotation of
the vehicle requires the use of specific
types of snow chain. Alfa Romeo Autho-
rized Services should first be contacted
before purchasing or using snow chains.
Check the tension of the chain after the
first few dozen metres have been driven.
IMPORTANTWhen driving on snow
with snow chains fitted, it might be
helpful to turn off the ASR function of
the VDC system (if present): in fact, in
these conditions, skidding of the driving
wheels when moving off makes it pos-
sible to obtain higher traction.

198IN THE EVENT
OF AN ACCIDENT
– It is important to keep calm.
– If you are not directly involved, stop
at a distance of at least ten metres from
the accident.
– On the motorway stop without ob-
structing the emergency lane.
– Turn off the engine and switch on the
hazard warning lights.
– At night, light the place of the acci-
dent with your headlights.
– Take care not to put yourself in dan-
ger of being run over.
– Signal the accident placing the reflect-
ing triangle plainly in view at the regula-
tion distance.
– Call the rescue organisation giving in-
formation as exact as possible. On motor-
ways use the special call boxes.
– In motorway pileups, especially with
poor visibility, the risk exists of being in-
volved in other crashes. Leave the vehi-
cle immediately and go over the guard
rail. The car is to be lifted
positioning the jack or
the workshop lift arm
plate only in the points shown
(1-2 fig. 100).
Between the lift plate and the
body interpose a rubber pad
with a maximum size of 60x60
mm and maximum thickness of
30 mm. The pad should insert in
the special recess on the under
door panel, without interfering
with it.
USING AN ARM LIFT OR
WORKSHOP LIFT
The vehicle must only be lifted laterally
positioning the ends of the arms or the
workshop lift in the areas (1-2) illustrat-
ed, approx. 30 cm from the profile of the
wheelhouse (fig. 100).
