ACTIVE SAFETY
SYSTEMS
The car has the following active safety
systems:
ABS (Anti-lock Braking System);
ESC (Electronic Stability Control)
system;
HH (Hill Holder) system;
ASR (AntiSlip Regulation) system;
DST (Dynamic Steering Torque
or steering corrector) system;
ERM (Electronic Rollover Mitigation)
system.
ABS (Anti-lock Braking
System)
43) 44) 45) 46) 47) 48) 49)
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the car
can be controlled even during
emergency braking and optimising
stopping distances.
The ABS also integrates the following
systems: EBD (Electronic Braking Force
Distribution), MSR (Motor
Schleppmoment Regelung) and HBA
(Hydraulic Brake Assist).IMPORTANT To obtain the maximum
efficiency of the braking system, a
bedding-in period of about 500 km is
needed: during this period it is better to
avoid sharp, repeated and prolonged
braking.
50) 51) 52)
System intervention
A slight pulsing of the brake pedal and
noise indicates the intervention of the
ABS: this is completely normal when
the system intervenes.
ESC (Electronic Stability
Control) SYSTEM
53) 54) 55) 56) 57) 58)
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the wheels
appropriately. The torque supplied by
the engine can also be reduced in order
to maintain control of the car.
System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.Switching the system on
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
GRAVITY CONTROL
(for versions/markets, where provided)
63)
It is an integral part of the ESC system
and is aimed at keeping the car at a
constant speed during a descent,
operating autonomously on the brakes
in various ways at the same time.
In this way, the “Gravity Control”
function assists the drive on steep
gradients in low-grip conditions and/or
on rough terrain.
For more information on system
operation, see the “Driving assistance
systems” paragraph in this chapter.
73
HH (Hill Holder) SYSTEM
59) 60)
This system is an integral part of the
ESC system and facilitates starting on
slopes.
The system is automatically activated in
the following conditions:
uphill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and
transmission in neutral or gear other
than reverse engaged;
downhill: car stationary on a road
with a gradient of more than 5%,
engine running, brake pressed and
reverse gear engaged.
ASR (AntiSlip
Regulation) SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration
on slippery, snowy or icy roads, etc. on
one or more drive wheels.
Engagement/disengagement of the
system
The system switches on automatically
each time the engine is started. The
ASR can be turned off and then turned
back on again whilst driving by pressing
the button located in the dashboard
fig. 63.When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
the driving wheels skidding when
moving off gives you better traction.
DST (Dynamic Steering
Torque or steering
corrector) system
61)
The DST (steering corrector) system
function uses the integration of the ESC
system with the electric power steering
to increase the safety level of the whole
car. In critical situations (e.g.
understeering, oversteering, braking
with different grip conditions), through
the DST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to be performed to
the driver.ERM (Electronic Rollover
Mitigation) SYSTEM
62)
The system monitors the tendency of
the wheels to rise from the ground if the
driver performs extreme manoeuvres
like quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground. It
is not possible to avoid tendency to roll
over if the phenomenon is due to
reasons such as driving on high side
gradients, collision with objects or other
vehicles.
WARNING
43)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce
the pressure, but hold it down firmly and
confidently; in doing so you will brake
in the shortest distance possible,
depending on the current road conditions.
44)For maximum efficiency of the braking
system, a bedding-in period of about
500 km is needed: during this period it is
better to avoid sharp, repeated and
prolonged braking.
