ABS operation
When a vehicle speed of about 10 mph (20 km/h) is reached, an au to
matic test sequence is run. Some noise from the pump may be
audible .
I f the speed of a whee l slows down too much relative to vehic le
speed and it starts to lock, brake pressure to this wheel is reduced.
This adj ustment process can be felt as a
pulsing motion of the brake
pedal ,
accompanied by some no ises. You as the driver are intention
a lly being given the infor mation tha t the wheels are tending t o lock
(ABS control range). In order for ABS to be ab le to operate optima lly
in this range, you must keep the b rake pedal depressed -do not
"pump the brakes".
Brake assistant
The brake power assist un it increases the pressure that you
genera te wi th the brake pedal. I t wo rks only when the e ngine is
running.
Automatic full braking
T his function al lows fu ll bra king in spite of high brake pedal forces
(e .g. whe n the brakes are seve rely s tressed beca use the veh ic le is
fully loaded) . T he driver not ices this function through a reduction of
pedal force a nd increased pedal t ravel. When the brake peda l is
re leased, fu ll braking assist switches off again automatically .
If there is an ABS failure, the brake assistant and automatic fu ll
brak in g ass ist are not available.
& WARNING
• ABS cannot suspend the la ws of physic s. You should keep this
in mind in parti cular on an icy or wet road . If ABS control of braking
intervenes , you should adjust your speed immediately to road and
traffic condit ions . Do not be tempted by the increased safety
provided to take risks -danger of an accident.
• Please keep in mind that the risk of an accident is increased by
driving too fast , particularly in bends and on icy or wet roads , and
& WARNING (continued )
by driving too close to the vehicle ahead . The increased risk of an
accident cannot be redu ced by the brake a ssistant -danger of an
accident .
[ i ] Tips
If a ma lfunction occurs in the ABS, this is signalled by an indicator
l ight, se e =>
pag e 20.
E ectro-mechan-;cal power assist
The electro -me chanical po wer assist helps the driver
w hen steering.
The degree o f pow er assis t is electronically matched t o ve h ic le
speed .
The power stee ring system as sists the driver so that he can steer the
vehic le with reduced physica l effort.
P ower steering wil l not work if the engine is off. As a result, the
s te eri ng wheel wi ll be hard to turn .
& WARNING
If the system develops a problem , you must seek qualified profes
s ional assist ance .
0 Note
If there is an electronic ma lfunction, servotronic wi ll st ill function
li ke a conve ntio nal power stee rin g system, prov iding a constant
steering support force that is no longer proportionate to the vehicle
speed. This is most no ticeable when turni ng the s teering wheel at
l ow speeds (for examp le when parking), -more effort will be
r e q uired than usual. ._

• Be aware of the different than usual steering response and
adjust your steering force accordingly.
• Have the problem checked and set right by an authorized Audi
dealer as soon as possible.
• If a steering malfunction occurs, this is signaled with the or.
~ indicator lights and a warning tone, see.
[ i] Tips
• If the power steering system should fail, or if the engine is not
running (for example, while being towed} , you will still be able to
steer the vehicle. However, more effort will be required to do so.
• If the power steering system is not functioning properly, contact
your authorized Audi dealer immediately.
Ap plies to vehicles : w ith A ll Wheel Drive
0 iving w i h your quattro®
With All Wheel Drive, all four wheels are driven.
General information
With All Wheel Drive, power is distributed to all four wheels. This
happens automatically depending on your driving style and the
road conditions at the time. See also=> page
184, "Electronic differ
ential lock (EDU".
Winter tires
When driving in the winter , your vehicle with All Wheel Drive has an
advantage, even with regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-season tires} for improved
driveability and braking : these tires must be mounted on all four
wheels. See also=> page 250, "Winter tires".
Controls and equip ment Safety first Vehicle operation
Intelligent technology
Snow
chains
Where tire chains are mandatory on certain roads, this normally
also applies to vehicles with All Wheel Drive=> page 251, "Snow
chains".
Replacing wheels/tires
Vehicles with All Wheel Drive must always have tires of the same
size. Also avoid tires with different tread depths . For details see
page => page 246, "New tires and replacing tires and wheels".
Off-Road driving?
Your Audi does not have enough ground clearance to be used as an
off-road vehicle. It is therefore best to avoid rough tracks and
uneven terrain as much as possible. Also refer to=> page 192.
& WARNING
Always adjust your driving to road and traffic conditions. Do not
let the extra safety afforded by All Wheel Drive tempt you into
taking extra risks.
• Although the All Wheel Drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at excessive speeds on icy or slippery
road surfaces.
• On wet road surfaces, be careful not to drive too fast because
the front wheels could begin to slide on top of the water (aqua planing}.
If this should occur, you will have no warning from a
sudden increase in engine speed as with a front-wheel drive
vehicle . Always drive at speeds which are suited to the road condi
tions. -risk of crash. •

& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage , such as
grease , oil , gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly,
espe cially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

& WARNING (continued)
• Never drive with run-flat tires if heat build-up causes the tire to
give off smoke .
• Never drive with run-flat tires if the vehicle shakes or vibrates
severely.
• Never drive with a run-flat tire that develops sidewall cracks or
other damage while in use .
0 Note
Run-flat tires have specia l characteristics and requirements, that are
very different from conventional tires. Run-flat tires require special
rims for run-flat use and cannot be used on conventional wheel
rims.
[ i] Tips
• I f you are not able to continue driving with run -flat tires, please
seek professional assistance.
• Please contact your authorized Audi dealer or Audi of America,
Inc . if you have questions about tires and rims. •
Applies to vehic les: with Run-flat t ires
Driving with run-flat tires
Handling characteristics change when tire pressure is
low.
Driving on tires with low tire pressure changes the way a
vehicle handles, particularly when cornering and braking.
The handling characteristics of run-flat tires do not seem to
change a lot even when driving on low pressure or in the
run-flat mode. Nevertheless you must still take special
precautions when operating a vehicle on run-flat tires when
tire pressure is low or the tire(s) is flat: The
Electronic Stabilization Program (ESP) must be
switched on.
- Never drive faster than 50 mph (80 km/h)~
&-
Plan ahead when driving and anticipate what you will
have to do considering traffic and road conditions up
ahead.
- Accelerate carefully.
- Avoid unnecessary and sudden steering and braking
maneuvers.
Reduce your speed in plenty of time before intersections,
curves and other places where you may have to react
quickly.
Please see:=> page 258, "When it is not possible to continue driving,
even with run -flat tires?"
Handling characteristics change when driving with
low air pressure or with flat tires even with special run
flat tires
A low pressure or flat front tire affects vehicle handling characteris
tics by pulling the vehicle slightly to the side where the tire is
mounted and reduces braking performance.
A low pressure or flat rear tire also affects driving characteristics by
pulling to the side where the tire is mounted and also reduces
braking performance. The effect on vehicle handling is most notice
able when driving around curves.
& WARNING
Changed vehicle handling characteristics when driving in the run
flat mode can cause loss of vehicle control, a crash and serious personal injury. .,,,
