Volvo XC90: Driver support / Auto-hold braking with driver support
The driver support functions Adaptive Cruise Control* and Pilot Assist* have
a special brake function in slow traffic and while stationary. In certain situations,
the parking brake will be applied to keep the vehicle at a standstill.
Braking function in slow traffic and at a standstill
In slow-moving, stop-and-go traffic or when stopped at a traffic light, driving
will resume automatically if the vehicle is stopped for less than approx. 3 seconds.
If it takes more than 3 seconds for the vehicle ahead to begin moving again, the
driver support function will go into standby mode and the auto-hold brake function
will activate.
- The function can be reactivated by:
- Pressing the
button on
the steering wheel keypad.
- Pressing the accelerator pedal.
- The function will resume following the vehicle ahead if it begins
to move within approx. 6 seconds.
WARNING
A noticeable increase in speed may follow when the speed is resumed with
the
steering wheel button.
WARNING
The driver support system only issues a warning for obstacles detected
by its radar sensor – thus, a warning may come after a delay or not at all.
- Never wait for a warning or assistance. Apply the brakes when necessary.
NOTE
Driver support can keep the vehicle stationary for no more than 5 minutes
– after that time the parking brake is applied and the function is deactivated.
The parking brake must be released before driver support can be reactivated.
Deactivation of the Auto-hold brake function
In certain situations, auto-hold will be deactivated when the vehicle is at a
standstill and the function will go into standby mode. This means that the brakes
will be released and the vehicle could begin to roll. The driver must actively apply
the brakes to keep the vehicle stationary.
This can occur if:
- The driver depresses the brake pedal.
- The parking brake is applied.
- The gear selector is moved to the P, N or R position.
- The driver puts Adaptive Cruise Control or Pilot Assist in standby mode.
Auto Activate Parking Brake
The parking brake will be applied if the function is keeping the vehicle stationary
using the brakes and:
- The driver opens the door or unbuckles his/her seat belt.
- The function has kept the vehicle at a standstill for more than approx.
5 minutes.
- The brakes overheat.
- The driver switches off the engine.

should maintain a time interval to the vehicle ahead.
