Volvo XC90: Starting and driving / Auto-hold brakes
With the Auto-hold brake function, the driver can release the brake pedal
and the brakes will remain applied, for example, when the vehicle has stopped at
a traffic light or intersection.
When the vehicle stops, the brakes are activated automatically. The function
can use either the normal brakes or the parking brakes to keep the vehicle stationary
and works on flat surfaces or hills. If the driver has their seat belt fastened
and/or if the driver's door is closed, the brakes will disengage automatically when
the vehicle starts driving.
NOTE
When braking to a stop on an uphill or downhill gradient, depress the brake
pedal with slightly more force than usual before releasing to ensure that the vehicle
cannot move at all.
The parking brake is activated if
- the vehicle is switched off.
- the driver's door is opened
- the driver's seat belt is removed
- the vehicle has been stationary for a prolonged period of time (5-10 minutes)
