Volvo XC90: Starting and driving / Parking brake malfunction
If you are unable to deactivate or activate the parking brake after several attempts,
contact an authorized Volvo workshop. A audible warning signal will sound if the
parking brake is activated while the vehicle is being driven.
If the vehicle must be parked before the problem is rectified, turn the wheels
as when parking on an incline and put the gear selector in P.
Low battery charge level
If the battery charge level is too low, it will not be possible to activate or
deactivate the parking brake. Connect an auxiliary battery to the vehicle if the
battery is discharged.
Replacing brake pads
Due to the design of the electric parking brake, the rear brake pads must be
replaced by a workshop. An authorized Volvo workshop is recommended.
