A WARNING
-Follow the installat io n instructions p rovided
with the roof ra ck sys tem. If you do not se
c u re the roof rac k sys tem and objec ts on the
roof cor rectly, they co uld come loose from
the vehicle and cause an accident .
- T he r is k of an accident increases when using
a roof rack system, because it changes the
driving c haracteristics by shifting the center
of gravity and/or the increasing the surface
area exposed to wind. You may need to
adapt your driv ing style and speed to the
current conditions . We recommend that you
do not dr ive faster tha n 80 mph (130 km/
h).
- Distribute the cargo evenly on the roof rack
and do not exceed the maximum width o r
the max imum tota l roof load weight .
- Before every tr ip, a ll bolts and co nnect ions
on the roof rack must be checked. Tighten
them if necessary and re che ck t hem regular
ly. If you do not do th is, there is a higher
risk of the roof rack o r the a ttachme nts
loosening or fa lling off .
(LlJ) Note
-If yo u use o ther roof l uggage rac k systems

- T o red uce the risk of damage, you must re
move the roof rack and attachment before
tak ing yo ur vehicle thro ugh an a utomat ic
car wash.
- Ma ke sure that the luggage compartment
lid and the panorama g lass roof* do not
come into contact with objects on the roof

@) For the sake of the environment
Your vehicle wi ll use more fue l due to the in
creased wind resistance. So remove the roof rack after us ing it.

Functional limitations
The radar sensors are des igned to detect the left

in the exte rior 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 t his 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 in the same lane
or one lane over from the adjacent lane .
- If s ide assist reacts to other objects (such as
roads ide structures like guard rails).
- In poor weather conditions . The side assist
functions are limited.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easi ly.
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
d isassemble them
C> _&. .
_& WARNING
Wheel bolts that are tight ened 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
e> page 356, 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 yourse lf, 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 trac
tion 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
e> & in
General information on page 325.
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 335.
340
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, re
gardless 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 .
(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, only
winter tires with the
& symbol may be per
mitted.
Snow chains
Snow cha ins not only improve the driving in win
ter road conditions, but also the braking.
"'Only install snow chains on the rear 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 (SO km/
h). Note 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 author
ized 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.S 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 .
_& WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
9"'

control, which increases the risk of an
accident.
@ Note
-Snow chains can damage the rims/wheel
covers* if the chains come into direct con
tact with them . Remove the wheel covers*
first. Use coated snow chains.
-Do not install and use snow chains if there is
a malfunction in the air suspension*, be
cause the vehicle height will be very low. If
you drive with snow chains anyway, the
wheel housings and other vehicle compo
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch the offroad mode on <=>

Low-profile tires
App lies to: ve hicles with low -profile tires
Compared to other tire/rim combinat ions, low
profile tires offer a wider tread surface and a
l arger r im diameter with shorter tire sidewalls.
This results in an agile dr iv ing style. However, it
may reduce the leve l of comfort and increase
road noise when driving on roads in poor condi
tion .
L ow -profile tires can become damaged more
quickly than standard tires when driving over
l arge bumps, potholes, manhole covers, and
curbs . Therefore, it is particular ly important to
maintain the correct tire pressure<=>
page 335 .
To reduce the risk of damage to the tires and
rims, drive very carefu lly on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. Fo r 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 immediate ly by
an authorized Audi dealer or authorized Audi
Service Facility .
Lo w-profile tires can wear out faster than stand
ard tires.

Uniform tire quality grading
-Tread wear
-Traction AA ABC
-Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width <=>
page 326, fig. 266.
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 cond it ions on a specified gov
ernment test course.
For example, a tire graded 150 would wear one
and one half (1 1/2) times as we ll on the govern
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual cond it ions of the ir use, however, and
may depa rt significantly from the norm due to
variations in driv ing 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 o n 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
c:>,& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
