.
112 03 Your driving environment
Transmission
All Wheel Drive - AWD1
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.
1Standard on certain models.
113 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.

1On vehicles with the optional keyless drive, the remote key must be in the passenger compartment.
CAUTION
Please check with state and local authorities before attempting this type of towing, as vehicles being towed are
subject to regulations regarding maximum towing speed, length and type of towing device, lighting, etc.
If the vehicle's battery is dead, do not attempt to start the vehicle by pushing or pulling it as this will damage the
three-way catalytic converter(s). The engine must be jump started using an auxiliary battery (see page 109
).
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the
flat bed. Consult the tow truck operator.
205 05 During your trip
Emergency towing
Towing vehicles with front wheel drive/All Wheel Drive
Volvo recommends the use of flat bed equipment.
If wheel lift equipment must be used, please use extreme caution to help avoid damage to the vehicle. In this case,
the vehicle should be towed with the rear wheels on the ground if at all possible .
If it is absolutely necessary to tow the vehicle with the front wheels on the ground, please refer to the towing
information on the page 204
.
CAUTION
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use sling -type equipment at the rear or apply lifting equipment inside the rear
wheels; serious damage to the rear axle may result.
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the
flat bed. Consult the tow truck operator.
