WARNING
Use of the cruise control could cause acci-
dents and sev
ere injuries if it is not possible

to drive at a constant speed maintaining the
safety
distance.
●
Do not use the cruise control in heavy traf-
fic, if the distance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
●
Never use the CCS when driving off-road or
on unpaved roads.
●
Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
●
To avoid unexpected operation of the cruise
control system, turn it off every time you fin-
ish using it.
●
It is dangerous to use a set speed which is
too high for the prevailing road, traffic or
weather conditions.
●
When travelling down hills, the CCS cannot
maintain a constant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle.

ment panels with indications in miles.
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
When travelling down hills the CCS cannot
maintain a constant speed. Slow the vehicle
down using the brake pedal and reduce
gears if required.
Automatic off
The cruise control system (CCS) is switched
off automatically or temporarily:
●
If the system detects a fault that could af-
fect the w
orking 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 in-
tervene (e.g. ASR or ESC).
●
If the brake pedal is pressed.
●
If the airbag is triggered.
