Brake function in slow queues and while stationary
For shorter stops in connection with inching in slow traffic or at traffic lights driving is automatically resumed if the stops do not exceed about 3 seconds - if it takes longer before the car in front starts moving again then the adaptive cruise control is set in standby mode with automatic braking.
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 following the vehicle ahead if it starts moving forward within 6 seconds.
ACC can keep the car stationary for a maximum of 10 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 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 position
- 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 takes place if the adaptive cruise control is 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. 10 minutes
- the brakes have overheated
- the driver switches the engine off manually.
