In certain cases, a vehicle will be classified as
cr itical for a la ne change even if it is still some
what far away. The faster a veh icle approaches ,
the soo ner the d isplay in the exterior mirror w il l
turn on.
@ Vehicles tra veling with you
Veh icles traveling with you are ind icated in the
exterior m irror if they are classified as critical for
a lane change. All ve hicl es detected by side assist
116
are indicated by the time they enter your "blind
spot", at th e latest .
@ Vehicle s left behind
If you slow ly pass a vehicle that s ide assist has
de tected (the diffe rence in speed between the
vehicle and your vehicle is less than 9 mph or
15 km/h), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot.
The display w ill not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ
ence in speed between the vehicle and your vehi
cle is greater than 9 mph or 15 km/h).
Functional limitation s
The radar sensors are designed to detect the lef t
and rig ht adjacent lanes whe n the road lanes are
the normal width . In certa in situations, the dis
play in the exterior mirror may turn on even
t hough there is no vehicle located in the area
that is crit ica l for a lane change. For example :
- if the lanes a re narrow o r if your are driving on
the edge of your lane . If this is the case, the
system may have detect ed the vehicle in anoth
e r lane that is
not adjacent to your current lane.
- if yo u are driving through a curve. Side assist
may r eact to a vehicle that is on e lane over
from the ad jacent lane.
- if side assist reacts to other objects (such as
high or disp laced guard rai ls) .
- In poor weather condit ions. The side assist
functions are limited .
Do no t cover the radar sensors ¢
fig. 130 wit h
stickers, deposits, bicycl e wheels or other ob
jects, because this wi ll affect the function. Do not
u se side assist when towing a trailer . For infor
mation on cleaning, refer to ¢
page 207.
A WARNING
-Always pay attention to traffic and to the
area around your veh icle . S ide assist cannot
replace a driver's attention . The driver alone
is always responsib le for lane changes and
sim ila r driv ing mane uve rs .
Care and cleaning
& WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci dents.
- To reduce the risk of cuts, protect yourself from sha rp metal components when wash
ing the underbody or the inside of t he wheel
hous ings.
- After was hing the vehicle, the braking effect
may be delayed due to mo isture on the
bra ke rotors o r ice i n the winte r. The bra kes
mus t be d ried first w ith a few care ful brake
applications .
@ Note
-If you wash the ve hicle in an automa tic car
wash, you m ust fold the exte rior m irrors i n
to reduce the risk of damage to the mirrors.
Power folding exterior m irrors * must on ly
be fo lded in and out using the power folding
funct ion.
- To reduce the risk of damage to the rims
and tires, compare the width between the
whee ls on your ve hicle w ith the distance be
tween the gu ide rails in the car wash. -
To red uce the risk of damage, compare the
heig ht and width of your vehicle with the
heig ht and w idth of the inside of the car
wash.
- To prevent paint damage, do not wash the
vehicle in direct sunlight.
- To reduce the risk of damage to the surface,
do not use insect removing sponges, k itchen
sponges or s imilar items.
- Matte finish painted vehicle components:
- To reduce the r isk of damage to the sur-
face, do not use polish ing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect.
- Do not place any stickers or magnetic signs on vehicle parts pain ted with matte
finish paint. The paint could be damaged
when the stickers or magne ts are re
moved.
@ For the sake of the environment
Only wash the veh icle in facilities spe cially de
signed for that pu rpose. This will reduce the
r isk of dirty wate r contamina ted with o il from
entering the sewer system .

A 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 acc ident. For the correct tightening specifi
cation, refer to ¢
page 260, 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 r ims repa ired by an
authorized Audi dealer o r autho rized Aud i
Service Facility . Never repair or d isassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac
tion on ice and snow .
"'U se winter t ires on all fo ur wheels .
.. Only use winter t ires that are approve d for your
v ehicl e.
"' Please note that the maximum permitted
speed may be lower with winter tires¢.&_ . An
authorized Aud i dealer or au thori zed Aud i Serv
ice Fac ility can inform you about the maximum
permitted speed fo r your tires .
"' Check the tire press ure after installing wheels
¢page 244.
The effectiveness of winter tires is reduced great
l y when the tread is worn down to a depth of
0 .1 57 inch (4 mm). The character ist ics of winter
tires a lso de crease great ly as the tire ages, re
ga rdless of the remain ing tread.
WARNING
- Never drive faster than the maxim um per
mitted speed for your t ires. This cou ld cause
the tires to heat up too much. Th is increases
Wh eel s
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose tract io n on black ice.
@ For the sake of the environment
Reinsta ll summer tires at the app ropr iate
time, beca use they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fue l
consumpt io n.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, on ly
winter tires w ith the
& symbo l may be per
mitted .
Snow chains
Snow chains improve traction in the snow.
"'On ly install snow chains on the rear wheels.
"' Check and correct the seating of the snow
chains if necessary after drivi ng a few feet. Fol
low the instructions from the manufacturer .
"' Note the maximum pe rmitted spe ed wh en dr iv
ing w it h snow cha ins. Do not excee d 30 mph

Low aspect ratio tires
Your Aud i is factory -equipped with low aspect ra
tio tires. These t ires have been tho roughly tested
a nd been se lected specifically fo r yo ur model fo r
thei r supe rb per fo rman ce , road feel and handling
un der a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re details .
T he low aspect ratio of these t ires is in dicated by
a nume ral of
55 or less in the tire's size desig na
tion . The numera l rep resents the rat io o f th e
tire's sidewall he ight in relat ion to its tread width
expressed in pe rcentage. Conventional tires have
a height/w idt h rat io o f 60 o r more .
The performance of low-aspect -ra tio tires i s par
ticularly sensitive to improper inflation pres
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at least once a month and always
before a long trip <=>
page 244.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, cu rbs, gullies or
250
ridges on the road, particularly if the tire is un
derinflated.
I n orde r to mi nimize the occur rence o f imp act
dam age to the tires o f yo ur vehicle, we recom
mend that you observe the following preca u
tions:
- Always m aintain reco mmende d in fla tion pres
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,00 0 km) and add air if necessary .
- Dr ive c arefully on ro ads w ith potholes, deep
gu llies o r ridges . The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your t ires.
- After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
unde rinflation, w hich could event ua lly cause
tire fa ilure . If you believe that a tire may have
be en damaged, replace the tire as soon as pos
sible .
- These tires may wear mo re quickly than o thers .
- Please also remember that, while these tires delive r responsive hand ling, they may ride less
comfortab ly and make mo re noise than o ther
choi ces.
Reduced performance in winter/cold season
conditions
A ll tires are des igned for certain purposes. The
l ow aspect ratio, ultra h igh performance tires
o rigin ally ins talle d on your veh icle are inten ded
for m aximum dry and wet road per forma nce and
handling . They a re not suitable for co ld, snowy or
i cy weather conditions . If you drive under those
c ir cumstances, you should equip yo ur vehicle
with all-season o r winter tires, which offer better
tract ion under t hose conditions. We suggest you
u se the recommended s now or all-season tires
spec ified for your vehicle, o r the ir equiva lent .
