- Side assist signal does not work around
t ight corners (turning radius less than
328 feet or 100 m).
- Side assist is no rep lacement for the driv­
er's full attent ion. The dr iver alone is re­
sponsible for lane changes and similar dr iv ing maneuvers . Always keep an eye
on the di rection yo u are traveling and the
relevant area around the vehicle.
(D Note
- To ensure that you do not adversely af­
fect side assist, do not block the area on
the rear bumper whe re the radar sensors
are located with foreign objects (such as
stickers o r bicy cle racks).
- Make sure that the signa l light on the
outside m irror is not blo cked by st ickers
or other items.
@ Tips
- Side assist a utomat ica lly deactivates if it
detects that the radar sensors a re
blocked E} page 93. The ind icator light
on the bu tton goes out.
- The area on the bumper where the radar
sensors are located must consis tently re­
main free of snow, ice, and heavy soiling
so that side assist can function properly .
Fo llow the additional notes on
c> page 93.
-Additional tinting on the front side win­
dows can make it harder to see and cor­
rectly understand the signa l light on the
outside mirror.

Applies to veh icles: w ith side assist
F ig. 89 Schemat ic ill ust rat ion : Sensor detect ion a rea
The detection c> fig. 89 of the radar sensor de­
tection area is made up of:
- the approach area (light red area)
(D , about
230 feet (70 m) behind the vehicle, and
- the "b lind spot" (dark red area)@.
T he rada r sensors cover the adjace nt left and
right lanes. Other lanes a re
not covered by the
radar sensors.
(0 Tips
Side assist does not measure a ctual lane
wid th. The system assumes a fixe d lane
width. Detection in the left and right lanes
is based on this assumed lane width .
When driv ing on narrow roads or when
driving to the left or right of the center of
a travel lane, it is possible that vehicles
will be detected that are
not in the lane
next to the lane you are us ing

Operation
Applies to veh icles: w ith s ide assist
S ide assist compares t he d istance and diffe r­
ence in speed of detected vehicles wi th the
speed of your vehi cle. Wheneve r the d iffe r­
ence in speed and distance is registered as no ­
tab le if you were to change lanes, a signal
li ght appears on the respective mirror.
T he signa l can ligh t up if yo u are passed by a
vehicle or if you are passing another vehicle.
If you pass another vehi cle slowly (difference
in speed less than 9 mph, o r 15 km/h), the ..,.

The informational stage signa l br ightness
should be adjusted so tha t you not ice the sig­
na l ill uminat ion when yo u loo k in the outside
mirror, but not when you look forward
throug h the windshield.
I n very da rk or light surroundings, the au to­
mat ic brightness setting adjusts s ignal light
brightness to maxim um or minimum intensi­
ty, as needed. In circumstances such as these,
you may not notice any change in the bright­
ness on the outside mirror when ad justing the
basic brightness . You may not notice the

Audi side assist: system fault
Have the system checked by an author ized Au­
di dealer or qualified workshop .
Audi side assist: not available when
to wing
T he radar sensor's view is limited when tow ­
ing a trai ler . F or vehicles with a facto ry instal ­
led towing hitch or a trailer hitch that was in­
stalled later according to factory specifica­
tions, side assist is automatically deactivated
a s soon as the electrical connection to the
trailer 's electrical socket is made, and this sta­
tus message appears in the instrument clus ­
ter display . Deactivation cannot be guaran­
teed when using a ret rofitted towing hitch
that was
not installed acco rd ing to facto ry
spe cifica tions.
Safety tips
Applies to vehicles: with side assist
T he side assist detection may be limited when
driving around narrow street corners, on hi lly
streets, and under poor weather conditions.
It is possible that the radar sensors may a lso
detect other objects, s uch as high or stag ­
gered guardrails .
S ide assist does not measure act ual lane
width. The system assumes a fixed lane width.
Detection in the left and right lanes is based
on this ass umed lane width . When driving on
narrow roads or when driving to the left or
right of the center of a travel lane, it is poss i­
ble that vehicles will be detected that are
not
in the lane next to the lane you are using .
A WARNING
-Improper reliance on the side assist sys­
tem can cause coll is ions and serio us pe r­
sonal injury:
- Never rely on ly on side assist when
changing lanes .
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un-
der all conditions- danger of accident!

Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sig n of the fac ility, the filte ring of the wash
water, the type of wash and care mater ial , etc.
If the pa int has a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a ca r wash, be s ure to
take the usual precautions such as closing the
windows and power roof. Factory installed an­
tennas m ust not be removed.
If you have installed additional accessor ies on
the vehicle -such as spoilers, roof rack, etc. -
it is best to ask the car was h operator if these
should be removed .
A WARNING
Always read and heed a ll WARNINGS and
other information

(D Note
- Fo ld the exterior mirro rs -flat there is a
r isk of damaging the exterio r mirrors .
Power folding exterior mirrors must not
be fo lded in or out by hand. Use the pow­
er function!
- Compare the track of your vehicle w ith
the d istance between the guide ra ils of
the facility- there is a risk of damage to
t h e wheels and tires .
- Compare the width of your vehicle wit h
the width of the tu nnel at the fac ility .

246 Tires and wheels
& WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of control.
- Always keep chemicals that can cause tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

contribution to good road holding and safe
handling when in good condition and properly
inflated
¢ .&. .
We recommend that all work on t ires and
wheels be performed by an authorized A udi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as we ll as the proper fa ­
cilities for dispos ing of the old tires .
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
R eplacing t ires and wheel s
Tires shou ld be rep laced at least in pairs and
not individua lly (for example both front tires
or both rear tires together).
Be s ure to read and heed the information to
the tire pressure monitoring system*
¢page 253.
Always buy rep lacement radial tires that have
the same specifications as the t ires approved
for your ve hicle by Audi. Replacement tires
must always have the same load rating speci ­
fication as the original equipment or approved
optional tires listed in the table
¢ page 239.
Audi-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving character istics, and safety of the
veh icle. The table
(¢page 239) lists spec ifica­

Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time
and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
deri nflated.
- For technical reasons it is not always
possible to use wheels from other vehi­
des -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat, increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on vehi­
cles that were equipped with them at the
factory. The vehicle must have a chassis designed for run flat tires . Incorrect use
of run flat tires can lead to vehicle dam­
age or accidents. Check with an author­
ized Audi dealer or tire specialist to see if
your vehicle can be equipped with run flat tires. If run flat tires are used, they
must be installed on all four wheels. Mix­
ing tire types is not permitted.
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
Tires and wheels 249
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible .
- Never drive without the valve stem cap .
The valves could get damaged.
@) For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
' Uniform tire quality grading
-Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
c:> page 246,
fig. 182.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (11/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how­
ever, and may depart significantly from the
norm due to variations in driving habits, serv­
ice practices and differences in road character-
istics and climate. .,.. •
