SERVICE AND EMERGENCY
BRAKES
Front:
– disc, floating caliper type with op-
erating cylinder for each wheel.
Rear:
– drum type with self-centring shoes
and operating cylinder for each wheel.
Crossed hydraulic circuit control.
7” vacuum brake booster.
ABS system with four sensors
(where fitted).
Automatic take-up of friction liner
wear.
Brake effort proportioning valves (2)
intervening on hydraulic circuit of the
rear brakes. HANDBRAKE
Controlled by a lever, it works me-
chanically on the rear brakes.
SUSPENSION
Front:
Independent wheel type, lower wish-
bones anchored to telescopic sup-
ports consisting of a cast iron riser
rigidly connected to a hydraulic dou-
ble action shock absorber. Leaf spring
and coaxial pads with the shock ab-
sorbers. Permanently lubricated joints.
Anti-roll bar anchored to the body
acting on suspension arm.
Rear:
Independent wheel with coil springs.
Jointed steel arms with bush and dou-
ble action telescopic gas shock ab-
sorbers. Water, ice and salt
sprinkled on the road de-
posit on the brake disc
and reduce effectiveness when
you brake.
Pay attention when in-
stalling extra spoilers, al-
loy wheels and non stan-
dard wheel caps: they could re-
duce the ventilation of the
brakes, thus reducing their effi-
ciency when braking suddenly
and frequently, or on long down-
hill slopes.

133TECHNICAL SPECIFICATIONS
STEERING
Jointed steering column with two
CV joints.
Permanently lubricated rack and pin-
ion.
Number of steering wheel turns lock
to lock (approximately) ................. 3.9
Minimum steering circle: 10.5 metres
(average between versions).
Electronically controlled power
steering system optional.
WHEELS
RIMS AND TYRES
Printed steel or alloy rims. Specific
wheel bolts (different in size and rec-
iprocally incompatible) for each of the
two types of rim.
Tubeless tyres with radial carcass.
The homologated tyres are listed in
the log book.
IMPORTANT In the event of dis-
crepancies between the information
provided in this Owner Handbook
and the Log Book, consider the spec-
ifications shown in the Log Book only.
To ensure safety of the car in move-
ment, it must be fitted with tyres of
specified size and of the same make
and type on all wheels.IMPORTANT Do not use inner
tubes with tubeless tyres.
Do not fasten alloy wheels with the
steel wheel bolts and vice versa. For
details on the compatibility between
rims and bolts - also with reference to
the space-saver spare wheel - see

0.3 bar should be added to the values given if the pressure is measured while the tyre is hot.
Check again the correct pressure when the tyres are cold.
