How your All Wheel Drive (AWD) system works
All Wheel Drive means that all four wheels on your vehicle are powered at the same time. The power is
distributed automatically between the front and rear wheels. A viscous coupling distributes the power
between the pair of wheels with the best traction in the current road conditions. This improves
roadholding and helps avoid wheel-spin.
In normal conditions, the majority of the power is distributed to the front wheels. The front wheels are
equipped with Volvo's anti-spin system TRACS, which is integrated with the car's ABS brake system.
Power to the rear wheels is regulated by a differential lock if one of these wheels should lose traction
when you start to drive off. The improved traction helps increase driving safety in the rain, snow and
freezing road conditions.
A freewheel module disconnects the power to the rear wheels when the brakes are applied in order to
give the car good braking stability.
WARNING!
Cars equipped with All Wheel Drive are not designed or intended for off-road driving.

Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
· Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
· Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
· To avoid overheating, the following rules should be followed:
Do not drive for prolonged periods at engine speeds above 4500 rpm if you are towing a trailer in hilly
terrain.
Reduce speed and downshift when towing a trailer up long, steep inclines. The risk of overheating can
be reduced by switching off the air conditioning system for a short time.
Do not let the engine idle unnecessarily for prolonged periods.
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes
