Brakes
The vehicle is equipped with two brake circuits. If one brake circuit is damaged, the brake pedal may go down further when depressed. More pressure will then be required from the driver for normal braking effect.
If the brake pedal is used when the vehicle is not activated, greater pressure must be applied to brake the vehicle.
In very hilly areas or when driving with a heavy load, gear position B can be used to augment the brakes with engine braking.
Anti-lock brakes
The vehicle is equipped with an Anti-lock Braking System (ABS1), which helps prevent the wheels from locking and helps maintain steering control when braking.
After the vehicle is activated, a brief test of the ABS system is automatically performed. Another automatic test of the system may be performed at low speed.
Light braking charges the hybrid battery
Energy is regenerated to the battery during light braking. This converts the vehicle's kinetic energy into electrical energy, which is used to charge the hybrid battery. When the battery is being charged using regenerative braking, this will be indicated in the instrument panel.
For harder braking, the braking is supplemented by the hydraulic brake system.
Note
Symbols in the instrument panel
| Symbol | Meaning |
|---|---|
  | A fault has occurred in the brake system. Read the message in the instrument panel and contact a workshop. Volvo recommends contacting an authorized Volvo workshop. |
  | A fault has occurred in the pedal sensor. |
  | Steady glow for 2 seconds after the vehicle is started: Automatic function check. Steady glow for more than 2 seconds: Fault in ABS system. The vehicle's regular brakes will still work, but without the ABS function. |
 | In the event of the message: Brake pedal characteristics changed Service required The brake pedal must be depressed with greater pressure, past the normal braking position, in order to brake the vehicle. |
Warning
If the warning symbols for both brake fault and ABS fault are lit simultaneously, there may be a fault in the brake system.
- If the brake fluid reservoir level is normal when this occurs, drive carefully to the nearest workshop to have the brake system checked - an authorized Volvo workshop is recommended.
- If the brake fluid has fallen below the MIN level in the brake fluid reservoir, the vehicle should not be driven until the brake fluid has been filled. The reason for the brake fluid loss must be checked.
