appears when you exceed the maximum
speed . It goes out when the speed falls below
the stored maximum speed.
The speed warning symbo l wi ll also go out if
the speed exceeds the stored maximum speed
by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed
is deleted .

Speed warn ing 2
Storing warn ing 2 is recommended if you al­
ways want to be reminded of a certa in speed ,
for example when you a re traveling in a coun­
try that has a general maximum speed limit,
or if you do not want to exceed a specified
speed for winter tires .
The speed warning 2 symbol, . (U SA mod ­
els)/ . (Canada models) appears in the dis­
p lay when you exceed the stored speed limit.
Unlike warning 1, it will not go out unti l the
ve hicle speed drops below the stored speed
limit.

@ Tips
Even though your vehicle is equipped with
a speed warning system, you should sti ll
watch the speedometer to make sure you
are not driving faster than the speed lim it.

If there is an electronic malfunction, ser­

w ill still function like a conven­
tional power steer ing system, providing a
constant steer ing support force that is no
longer proportionate to the vehicle speed.
This is most noticeable when turning the
steer ing whee l at low speeds (for examp le
when parking), -more effo rt will be re­
qui red than usual.
- Be awa re of the different than usual
stee ring response and adjust your stee r­
i ng force accord ingly .
- Have the problem checked and set right
by an Aud i dealer as soon as possible .
(D Tips
-When the engine is runn ing, never hold
the steer ing whee l turned a ll the way to
the right or to the left for longer than 15
seconds. The power s teer ing p ump w ill
overheat the hydraulic fluid if you keep ho lding the steering whee l turned a ll the
way . This is likely to damage the power
steering system .
- If the power steer ing system should fai l
entirely, or if the engine is not running
(for example, while being towed), you
will still be ab le to steer the vehicle .
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper­
l y, contact your authorized Aud i dealer
i mmediately.
- The power steering system requires a
spec ially formulated hydraulic fluid . T he
power steer ing reservo ir is the one locat­
ed farthest to the rear on the left side o f
the engine compartment
~ page 258.
The correct fluid leve l in the reservoir is
important for proper functioning of the
power steer ing .

Driving with your
quattro
With all-wheel drive , all four wheels are driv­
en .
Gener al info rmation
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
cond it ions at the time . See also
~ page 223.
Winter t i res
When d riving in the winter, your vehicle with
a ll-wheel drive has an advan tage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
a ll four
wh eels. See also ~ page 298, Winter tires.
Tire ch ains
Where tire chains are mandatory on certain
roads, this normally also applies to veh icles
with all-wheel drive~
page 299, Snow
chains .
Replacing whee ls/tire s
Vehicles with all-wheel drive must always
have tires of the same s ize . Also avoid tires
with different tread depths . For deta ils see
page ~
page 291, New tires and replacing
tires and wheels.
.8, WARNING
A lways adj ust yo ur dr iv ing to road and t ra f­
fic conditions . Do not let the extra sa fety
afforded by all-wheel drive tempt you into
taking extra risks.
- Altho ugh the a ll-wheel drive is very ef ­
fective, 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
(aquaplaning). If th is should occur, you •

& 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 risk of cuts, protect your­
self from sharp meta l components when
washing the underbody or the inside of
the wheel housings.
- After washing the vehicle, the braking ef­
fect may be delayed due to moisture on
the brake rotors or ice in the winter . The
brakes must be dried first with a few
careful brake applicat ions .
{[) Note
-If you wash the vehicle in an automatic
car wash, you must fold the exterior m ir­
rors in to reduce the r isk of damage to
the mirrors . Power folding exterior m ir­
ro rs* must only be folded in and out us­
i ng the power folding function.
- Compare the track of your vehicle w ith
the d istance between the gu ide ra ils of
the faci lity- there is a risk of damage to
the wheels and tires.
- Compare the height and width of you r
vehicle with the he ight and width of the
tunnel at the facility. -
To prevent paint damage, do not wash
the vehicle in direct sunlight.
- To 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 o r magnet ic
signs on vehicle parts painted w ith
matte fin ish paint. The pai nt 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 spe cially
designed for that purpose . This will red uce
the r is k of dirty water contam ina ted with
oil from entering the sewer system.

-If you notice unusual vibra­
tion 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.
(D Note
-Please note that summer
and winter tires are de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability.
Tires and wheels 273
If summer tires are used in
very cold temperatures, cracks can form on the tread
bars, resulting in perma­
nent tire damage that can
cause loud driving noise and unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.

"DOT" and indicates that the
tire meets all federal stand- ards. The next two numbers or letters indicate the plant where
it was manufactured, and the
last four numbers represent the
week and year of manufacture. For example, the numbers
2214 mean that the tire was
produced in the 22nd week of
2014. The other numbers are marketing codes that may or
may not be used by the tire
manufacturer. This information
is used to contact consumers if
a tire defect requires a recall.

298 Tires and wheels
Sustained high temperature can cause the
materia l 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 a ll passenger car tires must meet
under the Federa l Motor Veh icle 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 t ire is
based on stra ight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplanin g 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 fa ilure.
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, loca l governments
may require true winter or "snow" tires, those
with very deeply cut tread. These t ires 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 construct ion
type as the other tires on your ve hicle.
Your veh icle is equipped with all -wheel drive,
this will improve traction during w inter driv­
i ng, even with the standard tires. However, we
strongly recommend that you always equip all
four whee ls on your veh icle w ith correctly fit­
ted winter ti res or all-season tires, when win­
ter road conditions are expected. This a lso im- proves the vehicle's
braking performance and
reduces stopping distances.
Summer tires provide less gr ip 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 perm itted
winter tire sizes . Use
only rad ial winter t ires .
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0.157 inch
(4 mm).
Only drive w ith w inter t ires under winter con ­
ditions. Summer t ires 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 tire, see notes on spare
wheel<=>
page 291 .
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
was manufactured. Please see
<=>page 294,
Speed rating (letter code)
for a listing of the
speed rating letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code (<=>
page 2 76) is
on the side wall of the t ire
c> page 291.
A WARNING ,.___
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed before driv in g off. Never drive faster
than the speed permitted for your specific
winter tires. This wi ll cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING
'----
Driving faster than the maximum speed
for which the winter tires on your vehicle were designed can cause t ire failure in­
cluding a blowout and sudden deflation,

- Winter tires have maximum speed rating
that may be lower than your veh icle's
maximum speed.
- Never drive faster than the speed for wh ich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your driving to the road and traffic conditions . Never let the good ac­
celeration of the winte r tires and all-whee l
drive temp t you into taking extra r is k s. Al­
ways remembe r:
- When braking, an a ll-w heel driv e vehicle

@) For the sake of the environment
Use summe r tires when weathe r cond i­
tions perm it. They are quieter, do not wea r
as quickly and red uce fue l consumption.
Snow chains
Snow chains may be fitted on ly to the rear
wheels, and only to certain tire sizes . Ask yo ur
authorized Audi dealer on whic h tire sizes
snow chains can be used.
The snow chains must have low -profile links
a nd must not be thicker than 0 .S3 inch
(13 .5 mm), including the lock.
Remove wheel cente r covers and tr im discs
before p utting snow chains on you r vehicle
~ 0 . For safety reasons cover caps must the n
be fitted over the whee l bolts. These are avail­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in-

crease the risk of loss of contro l leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in­
structions prov ided by the snow chain
manufacturer.
- When driving with snow cha ins neve r
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
([) Note
-Remove snow c hains be fore driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con ­
tact with the whee l rim, can scratch or
damage it. Therefore, make sure that the
snow chains are s uitably covered. Check
t he pos itio n of the snow chains afte r

(D Tips
Where snow chains are mandatory oncer ­
tain roads, th is normally a lso applies to
vehicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
T he design of w heel bolts is matched to the
factory installed rims. If different rims a re fit­
ted, the correct wheel bolts with the right length and correct ly shaped bolt heads must
be used. Th is ensures that wheels are fitted .,..
