Volvo XC90: Starting and driving / Parking brake
The parking brake helps keep the vehicle stationary by mechanically locking
two wheels.

The parking brake controls are located in the tunnel console
between the seats.
When the electric parking brake is being applied, a faint sound can be heard
from the brake's electric motor. This sound can also be heard during the automatic
function check of the parking brake.
If the vehicle is stationary when the parking brake is activated, it will only
be applied to the rear wheels. If it is activated while the vehicle is moving, the
normal brakes will be used on all four wheels. Braking will be transferred to only
the rear wheels when the vehicle is almost stopped.
Regularly check the brake system components for wear.
To keep the vehicle as safe and reliable as possible, follow the Volvo service
schedule specified in the Warranty and Maintenance Records Information booklet...
