Deactivating the system
The HDC system is deactivated, but
remains available, if one of the following
conditions occurs:
the speed set for the HDC system is
canceled with 12 km/h, but set to
speeds below 40 km/h;
the vehicle is on a descent with
insufficient gradient, that is below 4%
or a level surface, or is going uphill;
the automatic transmission lever is in
P ("Park") position.
Disabling the system
The HDC system is deactivated and
disabled if one of the following conditions
is met:
the button shown in fig. 74 is pressed;
activation of mode other than 4WD
LOW;
driver side door open;
speed of 40 km/h exceeded
(immediate deactivation of the HDC
system).
Warnings for the driver
The appearance of the symbol
instrument panel display and the turning
on of the LED on the button shown in
fi g. 74 warn the driver of the status of the
HDC system:
the symbol
on the display of the
instrument panel and the LED on the
button turn on and remain on with
a fixed light when the HDC system
is enabled or activated. This is the
normal operating condition of the
HDC system;
the LED on the button flashes for a
few seconds, then turns off, when the
driver presses the button shown in
fig. 74 if the enabling conditions are
not satisfied.
ATTENTION
on the
51) In "Full Off" mode, the engine
torque reduction and stability functions
are deactivated. During emergency
maneuvers, the ESC system will not
engage to help maintain car stability. The
ESC disengagement mode was designed
exclusive for use on unpaved roads and
off-road.
52) A prolonged use of the system could
cause the braking system to overheat. If
the brakes overheat, the HDC system will
be gradually deactivated, if active, after
warning the driver (the LED on the button
will turn off); it can be reactivated only
when the brake temperature has gone
down enough. The distance that can be
covered depends on the temperature of
the brakes and therefore on the gradient,
load and speed of the car.
53) The capabilities of an HDC-equipped
vehicle must never be exploited in a
reckless or dangerous manner which
could jeopardize the driver's safety or the
safety of others.
