Automatic standby mode
Activation of automatic standby mode can be
due to one of the following:
•
The wheels are losing traction.
•
The engine speed is too low/high.
•
Brake temperature is too high.
•
Speed falls below 30 km/h (20 mph).
The driver must then control the speed him-
self/herself.

Adaptive cruise control*

The adaptive cruise control (ACC
47
) can help
the driver to maintain a constant speed, com-
bined with a preset time interval to the vehi-
cle ahead.
The camera and radar unit measures the distance to
the vehicle ahead.
An adaptive cruise control can provide a more
relaxing driving experience on long journeys on
motorways and long straight main roads in
smooth traffic flows.
The driver selects the desired speed and a
time interval to the vehicle ahead. If the cam-
era and radar unit detects a slower vehicle in
front of the car, the speed is adapted automat-
ically via the preset time interval to the vehicle.
When the road is clear again the car returns to
the selected speed.
If the cornering support* function is activated,
this may also affect the speed of the car.
The adaptive cruise control aims to:
•
regulate the speed smoothly. In situations
that demand sudden braking the driver
must brake himself/herself. This applies in
cases of large speed differences or if the
vehicle in front brakes suddenly. Due to
the limitations of the radar unit, braking
may come unexpectedly or not at all.
•
follow the vehicle ahead in the same lane
at a time interval set by the driver. If the
radar unit cannot see any vehicle in front
then the car will instead maintain the
speed set and stored by the driver. This
also takes place if the speed of the vehicle
ahead increases and exceeds the stored
speed.

This function can come as either standard or an option depending on the market.
