POWER STEERING
The hydraulic power steering is only ac-
tive when the engine is running. If the en-
gine is switched off greater effort will be
required to turn the wheel.
As the steering system is a mechanical
organ which is closely tied to driving
safety, the vehicle should be stopped and
Alfa Romeo Authorized Services contacted
if an anomaly is detected.
IMPORTANT Keep the steering wheel
turned at the end of its stroke, in both di-
rections, only for the strictly indispensable
time.
WINDOWS
Do not apply stickers or similar adhe-
sives to the windows as these may dis-
tract the driver and block his vision. The VDC system turns on automatically
when the car is started and cannot be
switched off. It is however possible to cut
off operation of the ASR system pressing
the corresponding button on the centre
console.
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.When changing the
wiper blades follow the
instructions contained in
the package which is available as
a spare part and read the indica-
tions given in the “Car mainte-
nance “ chapter of this booklet.
WINDSCREEN WIPER BLADES
The windscreen wiper blades should be
checked periodically. Dirty or worn blades
greatly reduce visibility. The windscreen
and windows should be cleaned regularly
and grease, dirt and tar removed. In this
way the life of blades will be extended
considerably.The VDC system helps
the driver to keep control
of the car in the event of loss of
tyre grip.
The forces induced by the VDC sys-
tem to control the lack of stability
of the car always and anyway de-
pend on the grip between the tyre
and the road surface.
WARNING
Before operating the windscreen wipers,
remove snow or ice from the windscreen
and check that the wiper blade is not
frozen to the windscreen. Use an an-
tifreeze product if necessary.
Do not operate the windscreen wipers
on dry glass.
