- Never let the vehicle ro ll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considera

booster assistance.
Servotronic - advanced
power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic power steering sys
tem senses the road speed and electronically
adjusts powe r assistance to provide comforta
b le and safe steering response exact ly match
ed to the vehicle speed.
Power steering w ill not work if the eng ine is
off. As a result, the steering wheel w ill be hard
to turn.
The power steering fluid level is checked dur
ing the scheduled ma intenance serv ices .
@ Note
If the re is an electronic malfunct ion, ser
votronic
w ill still function like a conven
tional power steer ing system, p roviding a
constant steer ing support force that is no
longer proportionate to the vehicle speed .
This is most noticeab le when turning the
steering whee l at low speeds (for examp le
when parking), -more effort will be re
quired than usual.
- Be aware of the different than usua l
steering response and adjust your steer i ng force accord ingly.
- Have the prob lem checked and set right
by an Aud i dealer as soon as possible.
- When the engine is running , never hold
the steering whee l turned all the way to
the right or to the left for longer than
15
seconds . The power steer ing pump w ill
overheat the hydraulic flu id if you keep holding the steering wheel turned all the
way . This is likely to damage the power
steering system.
- If the powe r stee ring system sho uld fail
entirely, or if the engine is not running
(for example, whi le be ing towed), you
will still be able to steer the ve hicle.
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper
ly, contact your author ized Audi dealer
immediately .
- The power steering system requ ires a
specially formulated hyd ra ulic fluid . The
powe r stee ring reservoir is the one locat
ed farthest to the rear on the left s ide of
the engine comp artment r=;,
page 259.
T he correct fluid level in the reservoir is
important for proper functioning of the
power steering .
Driving with your
quattro
With all-wheel drive , all four wheels are driv
en .
Gen eral information
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
condit ions at the time . See also r=;,
page 224 .
Winter tire s
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even wi th
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea
son tires) for improved dr iveability and brak
ing : these tires must be mounted o n
all four
wheels. See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to veh icles
with all-wheel driver=;,

A WARNING
-Only wash the vehicle when the ignition
is off and follow the instructions from
the car wash operator to reduce the risk of accidents .
- To reduce the r isk of cuts, protect your
self from sharp metal components when
wash ing the underbody or the inside of
t he wheel housings.
- After washing the vehicle, the braking ef
fec t may be delayed due to mo isture on
the brake rotors or ice in the winter. The
brakes must be dried first with a few
careful brake applications.
Q) Note
- If you wash t he vehicle in an automatic
car wash, yo u must fold the exterior m ir
rors in to reduce the r is k of damage to
the mirrors. Power folding exterior mir
rors* must only be folded in and out us
ing the power folding function.
- Compare the track of your vehicle with
the distance between the guide rails of
the facility -there is a risk of damage to
the wheels and tires .
- Compare the height and width of your
vehicle with the he ight and width of the
tunnel at the fac ility. -
To prevent paint damage, do not wash
the vehicle in direct sunlight.
- T o reduce the r isk o f damage to the sur
face, do not use insect removing spong
es, kitchen sponges or similar items.
- Matte finish painted vehicle compo nents:
- To reduce the risk of damage to the
surface, do not use polishing agents or
ha rd wax .
- Never use car wash cycles that apply protective wax.
It can destroy the
matte fin ish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The paint cou ld be
damaged when the stickers o r magnets
a re removed.
@ For the sake of the environment
Only wash the ve hicl e in facilities spec ially
designed for that purpose . This will red uce
the r is k of dirty water contam inated with
oil from entering the sewer system.

274 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age.

•
-All four wheels must be fitted with radial
tires of the same type, size (rolling cir
cumference) and the same tread pattern .
Driving with different tires reduces vehi
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time and drive with extra care. Refit the nor
mal road wheel as soon as safely possi
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air
flow to the brakes can them to overheat,
increasing stopping distances and caus
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them at the factory. The vehicle must have a
chassis designed for run flat tires. Incor
rect use of run flat tires can lead to vehi
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels . Mixing tire types is not permit
ted.
Tires and wheels 287
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 284,
fig. 253.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •
•
288 Tires and wheels
The relative performance of tires depends
upon the actual conditions of their use, how
ever, and may depart significantly from the norm due to variations in driving habits, serv
ice practices and differences in road character
istics and climate.
Traction
The traction grades , from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢.&, .
Temperature
The tempera ture grades are A (the highest),
B, and
C, representing the tire's resistance to
the generation of heat and its ability to dissi
pate heat when tested under controlled condi
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure~.&, .
The grade
C corresponds to a level of perform
ance which all passenger car tires must meet under the Federal Motor Vehicle Safety Stand
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
A WARNING
The temperature grade for this tire is es
tablished for a tire that is properly inflated
and not overloaded . Excessive speed, un
derinflation, or excessive loading, either
-
separately or in combination, can cause heat buildup and possible tire failure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F (7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true winter or "snow" tires, those
with very deeply cut tread . These tires should
only be used in pairs and be installed on all
four wheels . Make sure you purchase snow
tires that are the same size and construction
type as the other tires on your vehicle .
Your vehicle is equipped with all-wheel drive,
this will improve traction during winter driv
ing, even with the standard tires. However, we
strongly recommend that you always equip all
four wheels on your vehicle with correctly fit
ted winter tires or all-season tires, when win
ter road conditions are expected. This also im
proves the vehicle's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire sizes . Use
only radial winter tires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
O .15 7 inch
(4 mm).
Only drive with winter tires under winter con
ditions. Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7
°().
If you have a flat ti re, see notes on spare
wheel¢
page 284 .
Please always remember that winter tires may
have a lower speed rating than the tires origi-
nally installed on your vehicle at the time it .,.
