DRIVER SUPPORT

– The Adaptive Cruise Control is reactivated in
one of the following ways:
•
Press the steering wheel button
•
Depress the accelerator pedal.
> The Adaptive Cruise Control resumes fol-
lowing the vehicle ahead if it starts mov-
ing forward within 6 seconds.
NOTE
ACC can keep the car stationary for a maxi-
mum of 5 minutes. After this the parking
brake is applied and adaptive cruise control is
disengaged.
The parking brake must be released before
the adaptive cruise control can be reactivated.
Cessation of automatic braking
In some situations, automatic braking ceases on
reaching 0 km/h and Adaptive Cruise Control is
set in standby mode. This means that the brakes
are released and the car may start to roll - the
driver must therefore intervene and brake the car
himself/herself in order to maintain its position.
This may take place in the following situations:
•
the driver puts his/her foot on the brake
pedal
•
the parking brake is applied
•
the gear selector is moved to P, N, or R posi-
tion
276
•
the driver sets the adaptive cruise control in
the standby mode.
. Automatic activation of parking brake
In certain situations the parking brake is applied
to keep the car stationary.
This occurs if the Adaptive Cruise Control is hold-
ing the car still and:
•
the driver opens the door or takes off his/her
seatbelt
•
ACC has kept the car stationary for more
than approx. 5 minutes
•
the brakes have overheated
•
the engine is switched off.

Limitations of the Adaptive cruise
control*
The (Adaptive Cruise Control - ACC) may have
limitations in certain situations.
Bear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The function may have difficulty in
keeping the correct distance from the vehicle
ahead when driving on steep downhill slopes,
with a heavy load or with a trailer - in which case,
be extra attentive and ready to brake.
•
Off Road
Drive mode cannot be selected
when the adaptive cruise control is activated.
NOTE
The function uses the car's radar unit, which
has some general limitations, see the "Limita-
tions for radar unit" section.
