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
limiter prevents your vehicle from going faster
than the tire speed rating. For more information
9page257.
If the engine control unit receives faulty vehicle
road
speed s ignals, the Malfunction In d icator
Lamp (MIL) m will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance.
. _&WARNING
Always observe the posted speed limits and
adjust your 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
Introduction
Applies to: vehicles with speed warning system
The speed warning system helps you to stay un
der a specified maximum speed.
The speed warning system warns you if yo u are
exceeding
the max imum speed that you have set.
You will hear a warning tone when your speed ex
ceeds the stored value by approximately 3 mph
(3 km/h). The (e] indicator light turns on at the
same time in the Infotainment display. The[•)
indicator light turns off when the speed decreas
es below the stored maximum speed.
Setting a threshold is recommended if you would
like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener
al speed limit or if there is a specified maximum
speed for winter tires.

('D Tips
Regard less of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.
Setting the threshold
Applies to: vehicles with speed warning system
You can set, change and delete the warning
threshold
in the Infotainment system.

If the indicator light turns on, the steering wheel
may be more difficult to move or more sensitive
than usual. The steering wheel may also be at an
angle when driving straight.
Drive slow ly to an authorized Audi dealer or au
thorized Audi Service Facility to have the mal
function corrected.
@ Tips
If the. or '~ij indicator light only stays on
for a short time, you may continue driving.
ALL wheel drive (quattro)
In all wheel drive, all four wheels ore powered.
General information
In all wheel drive, the driving power is divided be
tween all four wheels. This happens automatical
ly depending on your driving behavior as well as
the current road conditions. c::> page 87, Electron
ic
stabilization control (ESC).
The all wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre
cautions c::> &..
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
c::> page 265, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid
wheels with different tread depths
c::> page 257, New tires or wheels.
Intelligent Technology
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult
terrain.
&,,!!_ARNING
-I
-Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acc i
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
h
igh speed when the road is slippery this in
creases the risk of an accident.
- Note
that on wet streets, the front wheels
can "hydrop lane" if driving at speeds that
are too high. Unlike front wheel drive
veh icl
es, the engine does not rev higher sud
denly when the vehicle begins hydroplaning .
For
this reason, pay attention to the road
conditions
regard less of your speed.

The extendoble rear spoiler increases driving sta
bility.

Wheels and Tires
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.
.,.Mark 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.
CD 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
250
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.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces. These compo
nents were bolted together using special bolts
and a special procedure. You must not repair or
disassemble them c::> .&..
&. WARNING
Wheel bolts that are tightened or repaired in
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi
cation, refer to c::> page 2 78, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
-
Only use wheel bolts that fit the rim.
- Always have
damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never
repair or disassemble
rims yourself, because this increases the risk
of an accident.
· Winter tires
Winter tires significantly improve the vehicle's
handling
when driving in winter conditions. Be
cause of their construction (width, compound,
tread pattern), summer tires provide less trac
tion on ice and snow .
.,. Use winter tires on all four wheels.
Downloaded from www.Manualslib.com manuals search engine ~Only use winter tires that are approved for your
vehicle.
~Please note that the maximum permitted
speed may be lower with winter tires q ,&.. An
authorized Audi dealer or authorized Audi Serv
ice Facility
can inform you about the maximum
permitted speed for your tires.
~Check the tire pressure after installing wheels
qpage260.
The effectiveness of winter tires is reduced great
ly when
the tread is worn down to a depth of
0.157 in (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re
gardless
of the remaining tread.
A WARNING
1-=---Never drive faster than the maximum per-
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk
of an accident because it can cause
the
tire to burst.
- Always
adapt your driving to the road and
traffic conditions. Drive carefully and reduce
your speed on icy or slippery roads.
Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free
of snow and ice. Summer
tires cause
Less road noise, tire wear and fuel
consumption.
(j) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where
winter tires are required, only
winter tires with the & symbol may be per
mitted.
Snow chains
Snow chains not only improve the driving in win
ter road conditions, but also the braking.
~Only install snow chains on the front wheels.
This applies also
to vehicles with all wheel
drive*.
Wheels
~Check and correct the seating of the snow
chains
after driving a few feet, if necessary. Fol
low
the instructions from the manufacturer.
~Note the maximum speed of 30 mph (50 km/
h). Note the Local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authori zed Audi dealer or author
ized Audi Service Facility
to see if you may use
snow chains .
You must remove the snow chains on roads with
out snow . Otherwise, you could impair driving
ability and damage the tires.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly
can result in loss of vehicle
control, which increases
the risk of an acci
dent.
CD Note
- Snow chains can damage the rims/wheel
covers* if the chains come into direct con·
tact with them. Remove the wheel covers*
first. Use coated snow chains.
-
Using snow chains that add more than 0.53
in (0.53 in) of height can severely damage
the wheel housings and
other vehicle com
ponents.
(D Tips
When using snow chains, it may be useful to
switch on sport mode ~page 88.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra
tio tires. These tires have been thoroughly tested
and been selected specifically
for your model for
their superb performance, road feel and handling
under a variety
of driving conditions. Ask your au
thorized Audi dealer
for more details .
The
Low aspect ratio of these tires is indicated by
a numeral
of SS or less in the tire's size designa
tion. The numeral represents the ratio of the
tire's sidewall height in relation to its tread width..,.

What you can do to avoid tire and rim
damage
L o w aspect ratio tires can be damaged more easi·
ly by impact with potholes, cu rbs, gull ies or
r i
dges o n th e roa d, pa rt ic u la rly ifthe tir e is un·
d e rinflated .
In order to minim ize the occu rrence of impact
damage to the ti res of your vehicle, we recom·
mend that you observe the fo llowi ng p recau ·
tions:
- Always
maintain recommended inflation p res·
sures. Check your tire pressure every 2,000
miles (3,000 km) and add air if necessary.
- Drive carefully on
roads with potholes, deep
gullies or ridges. The impac t from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause
damage to your tires.
- Af t
er any impact, immediately inspec t your
tires o r have them inspected by the nearest au
thorize d Audi dealer. Replace a da maged t ir e as
soo n a s possib le.
- In sp e

e a sy to
see. Damage can lead to loss of air and
un
deri n flation, which could eventually cause
tire failure. If you believe that a tire 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
deliver responsive handling, they may ride less
comfortably and make more no ise than other
choices.

Reduced performance in winter/co ld season
conditions
All ti res are designed fo r certain purposes. The
low
aspect ra tio, ultra high performance tires
originally installed on your vehicle are intended
for maximum dry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weather conditions. If you drive under those
circumstances, you should equip your vehicle
with all-season
or winter tires, which offer better
tract ion under those conditions. We suggest you
use the re commended snow or all-season tires
spe cified for your vehicle, or their equiva lent.
