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 approx. 3 seconds - if it takes longer before the vehicle in front starts moving again then the driver support function is set in standby mode with automatic braking.
The function is reactivated in one of the following ways:
- Press the steering wheel button .
- Depress the accelerator pedal.
The function resumes following the vehicle ahead if it starts moving forward within approx. 6 seconds.
A significant increase in speed may follow when the speed is resumed with the steering wheel button.
Driver supports only warn of obstacles which their radar unit has detected – hence a warning may not be given, or it may be given with a certain delay.
- Never wait for a warning or intervention. Apply the brakes when the situation requires.
The driver supports can hold the car stationary for a maximum of 5 minutes – then the parking brake is applied and the function is disengaged.
Before the driver supports can be reactivated, the parking brake must be released.
Cessation of automatic braking
In some situations, automatic braking ceases on coming to a standstill and the function 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 any of 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 or Pilot Assist to standby mode.
Automatic activation of parking brake
The Parking brake is applied if the function is holding the car stationary with the foot brake and:
- The driver opens the door or takes off his/her seatbelt.
- The function has kept the car stationary for more than approx. 5 minutes.
- The brakes have overheated.
- The driver switches the engine off.
