the ABS system is partly or completely deactivated and the brake system will work
as if no ABS is present. The wheels may then lock upon braking.

PARKING BRAKE AND SERVICE BRAKE
}
Always apply the parking brake when parking the vehicle. Do not
release the parking brake while the steering lock is still engaged.
The vehicle cannot be steered if the steering lock is still engaged.
The service brake is operated by the foot pedal. If the service brake fails to operate
owing to insufficient air pressure, the parking brake can be used as an emergency
brake. Moving the parking brake lever slowly backwards as far as the stop will
gradually brake the vehicle or combination in a controlled manner. The parking
brake is engaged by moving the parking lever back past the locking cam. On a
vehicle with a drawn vehicle connection, the parking brake has a test position. See
"Stopping". The parking brake is disengaged by lifting the locking ring up against the
spring pressure and letting the parking brake lever move forwards.
