Fi g. 98 Rear of vehicle: sensor pos itio ns
Side assist functions at speeds above approx i­
mately 19 mph (30 km/h).
@ Vehicles th at ar e approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still some­
what far away. The faste r a vehicle approaches,
the soo ner t he d isplay in the exter io r mirro r will
t ur n on.
@ Vehicl es traveling with you
Veh icles traveling w ith you are indicated in the
exte rior m irror if they are classified as cr itical for
a lane change. All ve hicl es detected by side assist
110
are indicated by the time they enter your "blind
spot", at the latest .
© Vehicles left behind
If you slow ly pass a veh icle that side assist has
de tected (the difference in speed be tween the ve­
hi cle and your ve hicl e is less than 9 mph o r 1S
km/h), the display in the exterior mirror turns on
as soon as the vehicle enters yo ur blind spot.
T he disp lay will not t urn on if you quickly p ass a
vehicle that side ass ist has de te cted (the differ­
ence in speed between the vehicle and your vehi­
cle is greater than 9 mph or 1S km/h).
Functional limitations
The radar senso rs are des igned to detect the left
and rig ht adjacent lanes when the road lanes a re
the norma l width . In some si tua tions, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti­
ca l for a lane change. For example:
- If the lanes are nar row o r if your are driving on
the edge of your lane. If t his is t he case, the
system may have detected the vehicle in anoth­
er lane that is
not adjacent to yo ur current lane.
- If you are driving t hro ugh a curve. S ide assist
may react to a vehicle that is one lane over from
the adjacent lane.
- If side assist reacts to other objects (s uch as
high or disp laced guard rails) .
- In poor weather conditions . The side assist
functions are limited.
Do no t cover the radar sensors ¢
fig. 98 with
stickers, depos its, bicy cle wheels or other ob ­
jects, beca use this will affect the function . For in­
format ion on cleaning, see
¢ page 235 .
_& WARNING
-Always pay attention to traffic and to the
area around your ve hicle. Side ass ist cannot
rep lace a dr iver's attention. T he driver alone
is always responsible for lane c hanges and
sim ila r driv ing mane uvers .
- In some s ituations, the system may not
fu nction o r its function may be limi ted . Fo r

load capacity of your vehicle.

for a specific tire.
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* consis t of mul tiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble them
Q ,& .
Tires and wheels
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 accident . For the correct tightening specifi­
cation, refer to~
page 242, A~er 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 traction on ice and snow.
.. Use winter tires on all four wheels.
.. 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
Qpage 224.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
-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.
229

Tires and wheel s
-Always adapt your driving to the road and
traff ic conditions. Dr ive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose tract io n 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 a nd ice. Summer
tires cause less road noise, tire wear and fuel
consumptio n.
(D Tips
You can also use all season tires instead of
w inte r tires. Please note that in some coun­
t ries w here winter tires are requ ired, on ly win­
t er tire s wi th the .& symbol may be pe rm it­
t ed.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
Th is applies also to veh icles with all wheel
drive* .
.,. Ch eck and correct the seating of th e snow
c h ains if necessa ry afte r dri ving a few feet. Fo l­
l ow the ins tructions from the manuf acturer.
.,. Note t he max imum permit ted speed w hen driv ­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
Snow chains not only improve the
driving in win ­
ter road conditions, but a lso t he
braking .
Use of s now chai ns is o nly pe rm itted with certa in
r im/t ire comb ina tion s due to techn ica l reason s.
Chec k w ith an au thori zed A udi d ealer or au tho r­
ized A udi Service Facility to see if yo u may use
snow cha ins.
Use
fine -mesh snow chain s. They mus t not add
mo re th an 0 .5 3 inch ( 13.S mm) in height, in clu d­
ing the chain lock.
You must remove the chai ns when dr iv ing on
roads tha t are
free of snow. W hen r oads are free
of snow, snow chains can imp air handling an d
230
'
damage the tires, and the chains wi ll quick ly be
dest royed.
A WARNING
Using incorrect snow chains o r insta lling snow
cha ins incor rectly can res ult in loss of veh icle
c o ntrol, which increases the risk of an acc i­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the c hains come into direct c on­
tact with them. Remove the wheel covers*
first . Use coa ted snow cha ins.
Low aspect ratio tires
Your A udi is fac to ry-eq uipped w ith low aspect ra­
t io t ires. These t ires have been thoroug hly tes ted
a nd been sele cted specifi ca lly f or your mode l for
the ir su perb pe rformance, r oad fee l and h andlin g
u nder a var iety of dr iv ing con ditions. As k your au ­
t h orized Aud i dea le r fo r more details .
The low aspe ct ratio of these tires is ind icated by
a n umer al of
55 or less in the t ire's s ize design a­
tion . The nume ral represents the ratio of the
ti re's si dewall height in relatio n to its tread width
expressed i n pe rcentage. Conventional tires have
a height/width rat io o f 60 o r more .
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to imprope r 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
b efor e a long trip
Q page 224 .
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged mo re eas i­
l y by impact w ith potho les, c urbs , g ull ies o r
r idges on t he road, pa rti cularly if th e tire is un ­
der i nflated.

Techni cal data
- Exceeding permiss ible weight ratings can
result in veh icle damage, acc idents and per­
sonal injury.
(D Note
- The vehicle capacity weig ht figu res app ly
when the load is d istributed evenly in the
vehicle (passengers and luggage). When
transport ing a heavy load in the luggage
compartment, carry the load as near to the
rear axle as possible so that the vehicle 's
hand ling is not impaired .
- Do not exceed the maximum permissib le
ax le loads or the maximum gross veh icle
we igh t. Always remember that the vehicl e's
hand ling will be affected by the e xtra load.
T herefore, adjus t your speed accordingly.
- Always observe local regulat io ns.
