2022 Volvo S90 Parking brake
Parking brake
The parking brake prevents the car from rolling away from stationary by means of mechanically locking/blocking two wheels.
- The control for the parking brake is located in the tunnel console between the seats.
- A faint electric motor noise can be heard when the electrically-operated parking brake is being applied. The noise can also be heard during the automatic function checking of the parking brake.
- If the car is stationary when the parking brake is activated, it only acts on the rear wheels. If it is activated when the car is moving then the normal foot brake is used, i.e. the brake acts on all four wheels. Brake function changes over to the rear wheels when the car is almost stationary.
Activating and deactivating the parking brake
Use the parking brake to prevent the car from rolling from stationary.
Activating the parking brake
- Pull the control upward.
- The symbol in the driver display illuminates when the parking brake is activated.

Automatic activation
The parking brake is activated automatically
The parking brake is activated automatically
- when the car is switched off.
- when gear position P is selected on a steep hill.
- if the automatic braking when stationary (Auto hold) function is activated and
- the car has been stationary for a long time (5-10 minutes)
- the car is switched off
- the driver leaves the car.
Emergency brake
In an emergency, the parking brake can be activated when the car is in motion by pulling and holding up the control. Braking stops when the control is released, or if the accelerator pedal is depressed.

Parking on a hill
Always make sure that the parking brake has been activated when parking on a hill.
Warning
Always use the parking brake when parking on an inclined surface. Engaging a gear or the automatic transmission’s P position is not sufficient to hold the car stationary in all situations. If the car is parked facing uphill:
- Turn the wheels away from the kerb.
If the car is parked facing downhill:
- Turn the wheels towards the kerb.
Heavy load uphill
A heavy load, such as a trailer, can cause the car to roll backward when the parking brake is released automatically on a steep incline. Avoid this by pulling the control upwards while driving the car away. Release the control when the engine achieves traction.

In the event of a fault in the parking brake
- Contact an authorised Volvo workshop if it is not possible to deactivate or activate the parking brake after several attempts.
- An acoustic warning signal sounds when driving with the parking brake activated.
- If the car must be parked before a possible fault is rectified, then the wheels must be turned as for parking on a hill and the gear selector must be in position P.
Low battery voltage
If the battery voltage is too low then the parking brake can be neither deactivated nor activated. Connect a donor battery if the battery voltage is too low.

Replacing the brake linings
The rear brake linings must be replaced at a workshop due to the design of the electrically-operated parking brake – an authorised Volvo workshop is recommended.
