Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed .
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You w ill hear a warning tone when your speed ex ­
ceeds the sto red val ue by app rox imately 3 mph
(3 km/h) . An indicator light . (USA mode ls)/ .
(Ca nada models) in the ins trumen t cluste r dis­
play a lso turns o n at the same time. The ind ic a tor
li ght .,. turns off w hen the speed decrea ses
below the stored maximum speed.
Set ting a t hreshol d is recom mended if you would
lik e to be rem inded when you re ach a cert ain
maximum speed . Si tua tions where you may want
to do so include drivin g in a country w ith a gene r­
a l speed limit or if there is a specified max imum
speed for winter tires.
(D Tips
Eve n though your vehicle is eq uipped w ith a
speed warning system, you should still watch
the speedometer to make sure yo u are not
drivi ng faster than the speed lim it.
Setting the threshold
You con set , change and delete the warning
threshold in the Infotainment system.
• Select: the ICAR I function button > (Car)* Sy s­
tems
control b utton > Driver ass istance >
Speed warning .
You can set any threshold betwee n 20 mph
(30 km/h) and 150 mph (240 km/h) . Settings
can each be adjusted in increments of 6 mph
(10 km/h) .

All wheel drive (quattro)
App lies to vehicles : with all wheel drive
In all wheel drive, all four wheels are powered .
General information
In all whee l dr ive, the dr iv ing power is divide d be­
tween all four whee ls. Th is happens automat ic al­
l y depending on yo ur driv ing behavior as well as
the cur rent roa d conditions . Refer to r=>
page 188,
Electronic Stabilization Control (ESC).
A cente r d iff eren tial distribu tes the d riving power
variably to the fron t and rear ax le . I t works to ­
gether w it h select ive whee l torq ue control, which
activates when driving throug h curves
<=> page 189. With the sport differential*, power
distribution to the rear wheels is variable a nd can
be adjusted with drive select<=>
page 101 .
The all whee l drive concept is designed for high
engine power . Yo ur vehicle is exceptionally pow ­
erfu l and has excellent driving characterist ics
bot h under normal driving conditions and on
snow and ice . Always read a nd follow safety pre­
ca utions
<=> ,& .
Winter tires
By using all whee l dr ive, your ve hicle has good
forward motion with sta ndard t ires in winter con­
dit ions . However, in winter we recommend usi ng
winter or all seaso n tires on a ll fou r wheels, be­
cause this will improve the braking eff ect.
Snow chains
If there are snow chain laws, snow chai ns m ust
also be used o n ve hicles with all wheel drive
r=> page 248 , Snow chains .
Replacing tires
For vehicles with a ll wheel drive, o nly wheels with
the same rolling circum ference should be used.
Avoid w heels with d ifferent tread dept hs

Wheels and Tires
General information
.,.Che ck 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.
"'Protec t your tires from oil,
grease and fuel.
.,.Ma rk 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 tem­
peratures, 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.

on tires or wheels performed by
an authorized Audi dea ler or au­
thorized repair fac ility. These fa­
cilities have the proper knowledge
and are equipped with the re­
quired tools and replacement
parts.
.,. New tires do not yet have the
optimum adhesion properties. Drive carefully and at moderate
speeds fo r the first 350 miles
(500 km) with new tires .
.,. Use tires of t he same constr uc­
tion, size (rolling c ircumference)
and as close to the same tread pattern as possible on all four
wheels.

- Only use wheel bo lts that fit the r im .
- Always have damaged rims repa ired by an
autho rized Aud i dealer or authorized repair
facility. Never repair or disassemble rims
you rself, because this increases the risk of
an acciden t.
Winter tires
Winte r tires sign ificantly improve the ve hicle's
handling when d riving i n w inte r condit io ns. Be­
cause of the ir constr uction (wid th, compo und,

The effect iveness of w inter t ires is red uced great ­
ly when the tread is worn down to a dep th of
0.1 57 i nch ( 4 mm). The cha racterist ics of winter
ti res a lso de crease grea tly as the t ire ages, re­
gardless of the remaining tre ad.
A WARNING
-
- Never drive faster than the max imum pe r­
m itted speed for your tires. This co uld cause
the t ires to heat up too much . This increases
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your dr iving to the road and
traffic cond itions. D rive carefully and reduce
your speed on icy or slippe ry roads. Even
win ter t ires ca n lose traction on black ice.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, beca use they provide better handling
when roads are free of snow and ice . Summer
tires cause less road noise, tire wear and fuel
consum ptio n.
(D Tips
You can a lso use all season tires instead of
winter tires. Please note that in some coun ­
tries where w inter t ires a re requir ed, only win ­
ter tires w ith the£ symbol may b e permit­
ted.
