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 regu-
late the vehicle's speed.
NOTE
If the accelerator pedal is only depressed
for a short time, such as when passing
another vehicle, ACC is deactivated tem-
porarily and is reactivated when the pedal
is released.
Automatic standby mode
ACC is linked to other systems such as the
stability and traction control system (DSTC). 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
Cruise control Cancelled is shown in the
instrument panel. The driver must then inter-
vene and adapt the vehicle's speed to the
surrounding traffic and regulate the distance
to the vehicle ahead.
An automatic switch to standby mode may be
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
•
brake temperature is high
•
the radar sensor is obstructed by, for
example, wet snow or rain.
Resuming the set speed
If ACC is in standby mode, it can be reactiva-
ted by pressing the
button on the steering
wheel keypad. The vehicle will return to the
most recently set speed.
WARNING
The vehicle may accelerate quickly after
has been pressed if its current speed is
considerably lower than the set speed.
Passing another vehicle
If your vehicle’s speed is being regulated by
ACC and the driver indicates that he/she
would like to pass the vehicle ahead by using
the left turn signal, ACC can assist by accel-
erating briefly.
This function is active at speeds above
approximately 45 mph (70 km/h).
