Assist systems

vehicles detected by side assist are indicated by
the time they enter your “blind spot”, at the lat-
est.
@ Vehicles you are passing
If you slowly pass a vehicle that side assist has
detected (the difference in speed between the ve-
hicle and your vehicle is less than 9 mph (15 km/
h)), the display in the exterior mirror turns on as
soon as the vehicle enters your blind spot.
The display will not turn on if you quickly pass a
vehicle that side assist has detected (the differ-
ence in speed is greater than 9 mph (15 km/h)).
Functional limitations
The radar sensors are designed to detect the left
and right adjacent lanes when the road lanes are
the normal width. In some situations, the display
in the exterior mirror may turn on even though
there is no vehicle located in the area that is criti-
cal for a lane change. For example:
— If the lanes are narrow or if you are driving on
the edge of your lane. If this is the case, the
system may have detected a vehicle in another
lane that is not adjacent to your current lane.
— If you are driving through a curve. Side assist
may react to a vehicle that is one lane over from
the adjacent lane.
— If side assist reacts to other objects (such as
high or displaced guard rails).
— In poor weather conditions. The side assist
functions are limited.
Do not cover the radar sensors > fig. 102 with
stickers, deposits, bicycle wheels or other ob-
jects, because they will impair the function. For
information on cleaning, see > page 235.

ZA WARNING
— Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention. The driver alone
is always responsible for lane changes and
similar driving maneuvers.
—Insome situations, the system may not
function or its function may be limited. For
example:

—If vehicles are approaching or being left
behind very quickly. The display may not
turn on in time.
— In poor weather conditions such as heavy
rain, snow or heavy mist.
— On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
() Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the system. Have
an authorized Audi dealer or authorized Audi
Service Facility check their function.
@ Tips
— If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be incor-
he Ges

vehicle. Consult this manual to
determine how this reduces
the available cargo and lug-
gage load capacity of your vehi-
cle.
>Check the tire sidewall
(=> page 214, fig. 177) to deter-
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily. You will need a special adapter to loosen
the anti-theft wheel bolts* > page 244.
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 > A.

ZA 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, see > page 247, Finishing.
— 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 significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,

228
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 > A\ in
General information on page 213. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
=> page 223.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter tires
also decrease greatly as the tire ages, regardless
of the remaining tread.
@) 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.
G) 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 win-
ter tires with the 4 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front 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). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or

8S1012721BB
Wheels

authorized Audi Service Facility to see if you may
use snow chains.
Use fine-mesh snow chains. They must not add
more than 0.53 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZA 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.
@) Note
Snow chains can damage the rims and wheel
covers* if the chains come into direct contact
with them. Remove the wheel covers* first.
Use coated snow chains.
@) Tips
When using snow chains, it may be advisable
to limit the ESC > page 106.
Low-profile tires
Applies to: vehicles with low-profile tires

Compared to other tire/rim combinations, low-
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style. However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi-
tion.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, and
curbs. Therefore, it is particularly important to
maintain the correct tire pressure > page 223.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/cracks
on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand-
ard tires.
Uniform tire quality grading
— Tread wear
— Traction AAABC
— Temperature A BC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width > page 214, fig. 177.
For example: Tread wear 200, Traction AA, Tem-
perature A.
All passenger car tires must conform to Federal
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 gov-
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band C. Those grades represent the tire's
ability to stop on wet pavement as measured un-
der controlled conditions on specified govern-
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
SA.
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
