Applies to: vehicles with four-wheel drive
The four-wheel drive system varies the distribution of power to the front and rear axles and thus improves the vehicle’s handling characteristics. It interacts with a selective wheel torque control, which may intervene when cornering link►.
(Applies to vehicles with quattro ultra: ) If four-wheel drive is not required for the current road conditions, the rear part of the drive train is uncoupled in order to save fuel. The system continuously analyses whether four-wheel drive is required. This allows the rear part of the drive train to be recoupled shortly before it is needed.
The four-wheel drive is specially designed to complement the superior engine power of your Audi. This combination gives the car exceptional handling and performance capabilities - both on normal roads and in more difficult conditions, such as snow and ice. Even so (or perhaps especially for this reason), it is important to observe certain safety points ►.
- Even with four-wheel drive, you should always adjust your speed to suit the conditions – risk of accident!
- The braking ability of your car is limited by the grip of the tyres. In this respect, your car is no different from a car without four-wheel drive. So do not be tempted to drive too fast – risk of accident!
- On wet roads bear in mind that the front wheels may start to “aquaplane” and lose contact with the road if the car is driven too fast. If this should happen, there will be no sudden increase in engine speed to warn the driver, as with a front-wheel drive car. So do not drive too fast in the wet: adjust your speed to suit the conditions (accident risk).
