Power steering
When the engine is running, power steering
makes i t easier for the driver to steer.
Power steering helps the driver steer the vehicle
with litt le physical effort.
If the engine is not running, the power steering
system is also not working. In this case, you will
find it extremely difficult to turn the steering
wheel.
If you turn the steering fully to the left or right
when the vehicle is stationary, you place a very
heavy load on the power steering system. Turning
the steering wheel fully to the left or right wi ll
cause noise in the system . It also reduces engine
idle speed.
(D Note
Do not hold the steering turned fully to the
left or right for more than 10 seconds when
the engine is running. There is a risk of dam
age to the power steering system.
@ Tips
- In the event of a power steering system fail
ure, or if the engine is not running (while
being towed), you will still be able to steer
the vehicle. However, you will require more
effort to do so.
- If the power steering system has a leak or is
defective, you should immediately contact a
qualified workshop .
- The power steering system requires a spe
cial hydraul ic fluid . The power steering fluid
reservoir is located in the engine compart
ment. The correct hydraulic fluid level is im
portant for proper operation of the power
steering system. The power steering fluid
l evel is checked according to the Audi main
tenance service schedule.
Dry sump lubrication
High lateral and longitudinal forces affect the en
gine and the vehicle during sporty driving. Dry
sump lubrication ensures that your engine is sup-
Intelligent technology
plied with oil and properly lubricated even under
these conditions.
In a "norma l" vehicle the oil pump sends the oil
from the oil pan to the lubrication points in the
engine . The oil then returns to the oil pan. In ex
treme situations, the oil pump may draw in air,
wh ich results in insufficient oi l pressure .
With dry sump lubrica tion, the oil is not in the oil
pan (it is "dry"), but in a separate oi l tank. While
one pump supplies the engine with oil, a second
pump suct ions the oil out of the engine and re
turns it to the o il tank. Because the oil tank is tall
and narrow, oil pressure is constant even under
extreme conditions .
In add ition, the oi l pan in vehicles with dry sump
lubrication is noticeably shallower . This allows
the engine to be installed lower in the vehicle,
bringing down the center of gravity . This im
proves your vehicle's handling.
Driving with your quattro
With oil-wheel drive, all four wheels are driven .
General information
With all-wheel drive, power is distributed to all
four wheels . This happens automatically depend
ing on your driving style and the road conditions
at the time . See also
c:::.> page 134.
The all-whee l drive concept is designed for high
engine power . Your vehicle is exceptionally pow
erful and has excellent driving characterist ics
both under normal driving conditions and on
snow and ice. Always read and fo llow safety pre
cautions

Winter tires
When driving in the winter, your vehicle with all
wheel drive has an advantage, even with regular
t ir es . In winter road condit ions it may be advisa
ble to mount winter tires (or all-season t ires) for
improved driveability and brak ing: these tires
must be mounted on
all four wheels. See also
