Standby mode due to action by the
driver
ACC is temporarily deactivated and put in
standby mode:
•
if the brakes are applied
•
if the gear selector is moved to N
•
if the driver drives faster than the set speed
for more than 1 minute.
In this happens, the driver will have to regulate
the vehicle's speed.

If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and is
reactivated when the pedal is released.

bility system. If this system is not functioning
properly, ACC will switch off automatically.
In the event of automatic deactivation, an audible
signal will sound and the message

the vehicle's speed to the surrounding traffic and
regulate the distance to the vehicle ahead.

caused if:
•
engine speed (rpm) is too high/low
•
The driver's door is opened
•
The driver unbuckles his/her seat belt
•
the vehicle's speed goes below 18 mph
(30 km/h)
•
the wheels lose traction
•

•
the radar sensor is obstructed by, for exam-
ple, wet snow or rain.
Resuming the set speed
If ACC is in standby mode, it can be reactivated
by pressing the
button on the steering wheel
keypad. The vehicle will return to the most
recently set speed.
