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 to keep it stationary.
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
•
the driver sets the adaptive cruise control in
the standby mode.
Automatic activation of parking brake
In certain situations the parking brake is applied

holding the car stationary with the foot brake 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 driver switches the engine off manually.
