Assist
Electronic speed Limiter
Your vehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
of your vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
lim iter prevents your vehicle from going faster
than the t ire speed rating. For mo re information
~page 262.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
L amp (MIL)
¢..ffi will illumina te. If this occurs,
con tact the nearest au thorized A ud i dealer for
assistance.
_& WARNING
Always observe the posted speed limits and
adjust you r speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed.
Speed warning system

Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 2 70, Snow chains.
Replacing tires
For vehicles with all wheel drive, only whee ls with
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 262, New tires or wheels.
Offroad vehicle?
Your Aud i is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain.
_&. WARNING
-Also, in vehicles with all wheel drive, adapt
your driv ing style to the current road and
t ra ffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the r isk of an acci­
dent.
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev highe r sud­
denly when the vehicle begins hydroplaning.
For this reason, pay attention to the road
conditions regardless o f your speed.

General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper knowledge and are equipped with
the required tools and replace­ ment parts .
.,.. New tires do not yet have the
optimum gripping properties.
Dr ive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
.,.. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels .
.,.. Do not replace tires individually.
At least replace both tires on the same axle at the same time.

tires or wide t ires are installed -
so only use the spare tire* tempo ­
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds . For this rea­
son, in case of emergency, only
use a spare tire* that is the same .,..

Winter tires
W inter tire s significan tly improve the vehicle 's
handling when driving in w inter condi tions. Be­
cause of the ir construction (width, compound,
tread pattern) , summe r tires p rovide less trac­
tion o n ice and snow.
.. Use w inter t ires o n all four wheels .
.. Only use w inter t ires that are approved for your
vehicle .
.. Please note that the maximum permitted
speed may be lower with winter tires

a utho riz ed Aud i dea le r o r authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed fo r you r tires.
.. Check the tire pr essu re after installing whee ls
¢ page 265.
The effectiveness of winter tires is reduced great ­
ly whe n the tread is wor n down to a depth of
0 .157 in (4 mm). The character istics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never dr ive faste r than the maxim um per ­
mitted speed for your t ires . This cou ld cause
the tires to heat up too much. This increases
t h e risk of an a cciden t be ca use i t can c ause
t h e tire to burst.
- Always adapt yo ur driv ing to t he r oad and
t ra ffic conditions. Drive ca refully and red uce
yo ur sp eed on icy or slippery roads. Even
winte r tires can lose traction on black ice .
@ For the sake of the environment
Reinstall su mme r tir es at the approp ria te
t ime, because they provide bet ter ha ndling
when ro ads are free of snow a nd ice. S ummer
t ires cause less road noise, ti re wea r and fuel
consumption.

(D Tips
You can also use a ll season tires instea d of
winter tires . Please note that in some coun­
tries where winter tires are required, on ly
winter tires w it h the

mitted.
' Snow chains
S now cha ins not on ly improve the driv ing in win­
te r road cond it io ns, but a lso the b raking .
.. On ly install snow chai ns on the front wheels .
T his applies also to vehicles with all wheel
dr ive*.
.. Check and co rrect t he seating of the snow
chains after driving a few feet, if nece ssary. Fol­
low t he inst ructions from the m anufac turer.
.. Note the max imum speed of 3 0 mph (50 km/
h). Note the local regulations.
U se of snow c hains is only permitte d wit h cert ain
rim/ tire comb inat ions due to technical reasons.
Check with a n authorized Audi dealer or author ­
i zed Audi Service Facility to see if you may use
snow chains.
You m ust remove the snow chains on roads wi th­
out snow . Otherwise, you co uld impair driving
ability and damage the t ires .
A WARNING
Using incor rect snow chains or installing snow
cha ins incor rectly can result in loss of vehicle
control, which increases the risk of an acci­
dent .
(D Note
-Snow chains can damage the rims/wheel
covers* if the c hains come into direct con­
tact with them. Remove the w heel covers *
first . Use coated snow cha ins .

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
tio tires. These t ires have been thoroughly tested
and been selected specifically for your model for
their supe rb performance, road feel and handling
u nder a va riety of d riving conditions. As k your au­
thor ized Audi dealer for mo re details.
The low aspect ratio of these t ires is indicated by
a numeral of
55 or l ess in the tire's size designa­
tion. The numera l rep resents the rat io of the
tire's sidewall he igh t in relat io n to its tread w idth
expressed in pe rcen tage. Conventional t ires have
a height/w idth rat io of 60 or more .
The performan ce of low -a spe ct-ratio tire s is par­
ticular ly sen sit iv e to improper inflation pre s­
s ur e. It i s therefore import ant that low a spect
ratio tire s are infl ate d to the specified pre ssure
and that the inflation pre ssure i s regularl y
c hecked and mai nta ined . Tir e pre ssure s should
b e che cked at least once a month and alw ay s
before a long tri p ¢
page 265.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi­
ly by impact with potholes, curbs, gullies or
ridges on the road, particularly if the t ire is un­
derinflated .
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the follow ing precau­
tions:
- Always maintain recommended inflation pres­
sures. Check your tire pressure every 2,000
miles (3,000 km) and add a ir if necessary .
- Drive carefully on roads with potho les, deep
gul lies or ridges. The impact from driving
t h rough or ove r such obstacles can damage
you r tires. Impact w ith a curb may also cause
damage to your tires.
Wh eel s
- After any impac t, immed iate ly inspect your
tires or have them inspected by the nearest au­ thorized A udi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 mi les (3,000 km)
for damage and wear. Damage is not a lways
easy to see. Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure . If you believe that a t ire may have
been damaged, replace the tire as soon as pos­
sible.
- These tires may wear more quickly than others.
- Please also remember that, while these tires
delive r responsive handling, they may ride less
comfortably and make mo re noise than other
choices.
Reduced pe rfo rmance in winter /cold season
conditions
All t ires are des igned for certai n purposes. The
low aspect ratio, ultra h igh performance tires
o rigi na lly installed o n your vehicle are intended
fo r m aximum d ry and wet road per formance and
handling . They are not sui table for co ld, snowy or
icy weather conditions . If you drive under those
circumstances, you should equip yo ur vehicle
with all-season or winter tires, which offer better
tract ion under those conditions. We suggest you
use the recommended snow or all-season tires
specified for your veh icle, or their equivalent.
