Vehicles equipped

As soon
as
the engine
is
started, the electronic control unit carries
out
a self-diagnosis.
The relevant dashboard warning lamp lights up and remains on
for
2 seconds and then goes
out.
In
the event
of
a system failure,
the
lamp remains on permanently.
In
this
case
refer
to
an
Authorised Dealer.

b.
Chassis lifting/lowering (positions a
or
b)
This operation
can
only
be
carried
out
with the vehicle at a standstill
or
when it
is
running at the max speed
of
I
Okm/h.
The warning lamp
lights up at slow intermittent intervals (every
2"
approx) during the lifting/lowering operations and
also
when max high/Iow
levels
have
been attained. A faster blinking (every 1/2")
of
the
lamp indicates either
chassis
overloading
or
a failure
in
the air
system.
In
the latter
case,
refer
to
an
Authorised Dealer.
Should the travelling speed
exceed IOkm/h, the preselected
chassis
level
is
maintained:
however avoid high speeds
if
possible
or
revert
to
normal conditions (position 0).
Cargo loading/unloading. chain fitting and travelling, uphill running
have
been considerably facilitated
by
the
introduction
of
this system.
