position so that the vehicle can be moved1 . Lift away the rubber mat on the floor of the storage compartment behind the center console and open the hatch. Insert the key blade into the opening as far as possible. Press the key blade down and keep it held down. Move the gear selector from the P position. For information on the key blade, see page 48. All Wheel Drive - AWD 2 Your Volvo can be equipped with permanent All Wheel Drive, which means that power is distributed automatically between the front and rear wheels. Under normal driving conditions, most of the engine's power is directed to the front wheels. However, if there is any tendency for the front wheels to spin, an electronically controlled coupling distributes power to the wheels that have the best traction. 1 If the battery is dead, the optional electric parking brake cannot be applied or released. Connect an auxiliary battery if the battery voltage is too low, see page 104. 2 Standard on certain models. 107 03 Your driving environment Brakes Brake system The brake system is a hydraulic system consisting of two separate brake circuits. If a problem should occur in one of these circuits, it is still possible to stop the vehicle with the other brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pressure, the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault has occurred. If this light comes on while driving or braking, stop immediately and check the brake fluid level in the reservoir. NOTE Press the brake pedal hard and maintain pressure on the pedal - do not pump the brakes. WARNING If the fluid level is below the MIN mark in the reservoir or if a brake system message is shown in the information display: DO NOT DRIVE. Have the vehicle towed to a trained and qualified Volvo service technician and have the brake system inspected. Power brakes function only when the engine is running The power brakes utilize vacuum pressure which is only created when the engine is running. Never let the vehicle roll to a stop with the engine switched off. If the power brakes are not working, the brake pedal must be pressed approximately five times harder than usual to make up for the lack of power assistance. This can happen for example when towing your vehicle or if the engine is switched off when the vehicle is rolling. The brake pedal feels harder than usual.
