Driving
The CSS only reduces vehicle speed by
ceasing t
o accel
erate, not by actively braking
the vehicle

Depending on the equipment, the cruise con-

ol can be oper
ated using the lever of the
turn signals

The CCS is switched on. The set speed is

Changing gear in CCS mode
The CCS decelerates as soon as the clutch
pedal is pressed, intervening again automati-
cally after a gear is engaged.
Travelling down hills with the CCS
If the CCS cannot maintain a constant vehi-
cle speed downhill, brake and change down
a gear if necessary. The GRA is temporarily
disabled by pressing the brake.

Automatic off
The GRA disconnects aut
omatically or is
t
emporarily interrupted:
●
If the system detects a fault that could af-
fect the working order of the CCS.
●
If you press and maintain the accelerator
pedal for a certain time, driving faster than
the stored speed.
●
If the dynamic driving control systems inter-
vene, ASR, ESC, etc.
●
If the brake pedal is pressed.
●
If the airbag is triggered.
●
If the lever is taken out of the D/S position.
WARNING
Use of GRA could cause accidents and se-
ver
e injuries if it is not possible to drive at a
constant speed maintaining the safety dis-
tance.
●
Do not use GRA in heavy traffic, if the dis-
tance from the vehicle in front is insuffi-
cient, on steep roads, with several bends or
in slippery circumstances or on flooded
roads.
●
Never use the CCS when driving off-road
or on unpaved roads.
●
Adapt your speed and the distance to the
vehicles ahead in line with visibility, weath-
er, the condition of the road and the traffic
situation.
●
To av
oid unexpected operation of the
cruise control system, turn it off every time
you finish using it.
●
It is dangerous to use a set speed which is
too high for other conditions.
●
If driving down a steep gradient, the GRA
cannot maintain a constant speed. The
speed can increase. In this case, brake and
change down a gear.
