Setting the warning point and steering
wheel vibration
Applies to vehicles: with lane assist
You can adjust individual settings in the MMI.
.. Se lect: ICARI function button> Car systems
control button > Driver assist > Audi lane
assist .
Setting the warning point
Early: With this setting, a warning is provided
before a wheel touches the detected lane
boundary line . The warning depends on the
angle in which the veh icle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you dr ive towa rd a boundary line at a very
sha rp angle, the warning will come just before
a wheel touches the line.
Medium : With this setti ng, the warn ing po int
is adapted to the course of the road, the lane
width and the speed. You wi ll sti ll be warned
if you cross slightly over a dotted line when
driving on curves.
Late : This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel v ibration can be set to
Low , Medium or Strong . Selecting each of the
settings will cause the steering wheel to vi­
b rate so you can check the strength of the vi­
bration in that setting.
(D Tips
Your settings are automatically stored and
assigned to the remote contro l key being
used .

Side assis t fu nctions at speeds above ap prox i­
ma tely 19 mph (30 km/h).
(D V ehicles that are approaching
In certain cases, a vehicle will be classified as
cr itical for a lane change
even if it is still
somewhat far away. The fas ter a vehicle ap­
p ro aches, the sooner the disp lay in the exteri­
or m irror will t urn on.
@ Vehicles traveling with you
Vehicles traveling w ith you are indicated in the
exterior m irror if they are classified as cr it ical
for a lane change. All vehicles detec ted by
side assis t are in dicated by the time they en­
ter your "blind spot", at the latest.
@ Vehicles left behind
If you s low ly pass a ve hicl e tha t sid e ass ist has
dete cted ( the difference in s peed between the
vehicle and you r vehicle is less than 9 mph or
15 km/ h), the display in the exterio r mirror
turns on as soon as the vehicle enters your blind spot.
The display wi ll not t urn on if you quickly pass
a vehicle that s ide assist has detected (t he d if ­
f erence in speed between the ve hicle and your
vehicle is greater than 9 mph or 15 km/h).
Functional limitations
T he radar senso rs are designed to detect the
left and right adjacent lanes when the road
l anes a re the normal width. In certain situa­
t ions, the d isp lay in the exterior mirror may
turn on even though there is no ve hicle locat­
ed in the area that is cr itical fo r a la ne cha nge.
Fo r example:
- if the lanes are narrow or if your are driving on the edge of your lane. If this is the case ,
the system may have detected the vehicle in
another lane that is
not adjacent to you r
cur rent lane .
- if you a re driving through a c urve . Side assis t
may react to a vehicle that is one lane ove r
from the adjacent lane .
- if side assist reacts to other objects (such as
high or d isp laced gua rd rails) .
- In poor weather conditions. The side assist
fu nctions are limited .
Do not cover the radar sensors
c::> fig. 111 with
stickers, depos its, bicycle wheels or other ob­
jects, because this wi ll affect the funct io n. Do
not use s ide ass ist when towing a trailer . For
information on cleaning, refe r to

&_ WARNING
-Always pay a tten tion t o traffic and to the
a rea around your ve hicl e. Side a ssist can ­
no t repla ce a driver's atte ntion. The driv ­
er a lone is always respons ible fo r lane
cha nges a nd similar driving mane uvers.

216 Cleaning and protec tio n
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
sign of the facility, the filte ring of the wash
water, the type of wash and care mater ial , etc.
I f the pa int has a dull appearance afte r going
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 car wash, be sure to
take the usual precautions such as closing the
windows and power roof . Factory installed an­
tennas must not be removed.
I f you have installed additional accessor ies on
the vehicle - such as spoilers, roof rack, etc. -
it is best to ask the car wash operator if these
should be removed .
When driving through an automatic car wash,
fi rst se lect the N position and then switch the
engine off. If you switch the engine off when N is engaged, the transmission remains in N
for approximately 30 m inutes and then Pis
engaged.
Further information for automatic gearboxes
~ page 115.
A WARNING
Always read and heed all WARNINGS and
other information
r:::;, page 215.
- Before washing the vehicle in an auto­
matic car wash, p lease make sure to re­
tract the exterior mirrors to prevent
them from being damaged. Power fold­ i ng exter ior mirrors must not be folded
i n or out by hand . Always use the electri­
ca l power control.
- Compare the track of your vehicle with the d istance between the guide rails of the facility - the
re is a risk of damage to
the whee ls and tires .
- Compare the height and width of your
vehicle with the height and width of the tunnel at the facility .
Washing the vehicle by hand
A lot of water is needed when washing a vehi ­
cle by hand.
.,. Before yo u start washing, make su re you
have read and understood the WARNINGS
~ A in General information on page 215.
.,. First soak all dried dirt unti l it is soft, then
rinse it off.
.,. As you clean your vehicle, start with the
roof and work your way down to the bottom,
using a sponge, a sponge glove or a clean brush .
.,. Rinse the sponge o r the sponge g love often,
flushing it clean each time.
.,. Use spec ial car shampoo only for very per­
sistent dirt .
.,. Rinse the car thoroughly with water.
.,. Use a chamois leather to gently wipe the ex-
ter ior dry.
Use a separate sponge for cleaning the
whee ls , door si lls and other regions exposed
to road dirt. In this way, you will not scratch
the pa int with coarse particles imbedded in
the sponge the next time you wash the car.
A WARNING
-- Wash your vehicle only when the ign ition
is switched off to reduce the risk of a
crash.
- Do not clean the underside of the chas­ sis, fenders, wheel covers, or other hard
to reach parts without protect ing your
hands and arms . You may cut you rself on
sha rp-edged metal pa rts.
- Always read and heed all WARNINGS and other info rmation

260 Tires and wheels
-Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pared to all-wheel drive (quattro ®).
- Please rotate tires as shown
¢fig. 207.
- Extra care must be taken when rotating di-
rection-specific tires
¢ page 2 78.
Wheel balancing
The wheels on new vehicles are balanced .
H owever, various situations during everyday
driving can cause them to become unbal­
anced , resu lting in vibrations you can usually
feel through the steering wheel.
Unba lanced wheels must be rebalanced to
avoid excessive wea r on steering , suspens ion
and tires . A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect whee l alignment can cause exces­
sive tire wear, impair ing the safety of the vehi­
cle .
If tires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Vehicles with quattro® must always have ti res
of the same size, construction and tread type.
F or details see
¢page 203.
A 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 "hydrop laning" 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 specia
l 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.

-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.
- All four wheels must be fitted with radial
tires of the same type, size (rolling cir­
cumference) and the same tread pattern.
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
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles - 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
vehicles that were equipped with them
at the factory. The vehicle must have a
chassis designed for run flat tires. Incor­
rect use of run flat tires can lead to vehi­
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
Tires and wheels 263
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels. Mixing tire types is not permit­
ted.
@ Note
- 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.
- 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
~ page 260,
fig. 208 .
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
unde r contro lled conditions on a specified
government test course. •
•

tread width expressed in percentage. Conven­
tional tires have a height/width ratio of 60 or
more .
The performan ce of low-aspe ct-ratio tires is
particularly sensitive to improper inflation
pressure . 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 pres­
sures should be checked at least once a
month and always before a long trip
¢ page 2 55, Checking tire pressure .
What you can do to avoid tire and rim
damage
L ow aspect ratio tir es can be damaged more
eas ily by impact with potho les, curbs, gu llies
or r idges on the road, part icu larly if the tire is
under inflated.
In order to minimize the occurrence of impact
damage to the tir es of your veh icle, we recom­
mend that you observe the following precau­
tions :
- Always maintai n recommended inflation
pressures . Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary.
- Drive carefully on roads with potholes, deep
gullies or r idges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso
ca use damage to your tires .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
autho rized Audi dealer. Replace a damaged
t ir e as soon as possible.
- Inspect yo ur tires every 2,000 miles (3,000
km) for damage and wear. Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ich could eventu­
ally cause tire failure . If you be lieve that a
t ir e may have been damaged, replace the
t ir e as soon as poss ible .
- These tires may wear more quick ly than oth ­
ers .
- Please a lso remember that, while these tires
deliver respons ive handling, they may ride
Tires and wheels 267
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather conditions .
If
you drive under those circumstances, you
shou ld equip your vehicle w ith all-season or
winter tires, which offer better t raction unde r
those conditions. We suggest you use the rec­
ommended snow or all- season tires specified
for your vehicle, or their equivalent.
Refer to~
page 264 for more detailed infor ­
mation regarding winter tires.
Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith t ire pressure monitoring syste m
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended
by the vehicle man ufacturer on the vehicle
placard or tire inflation pressure labe l. (If your
vehicle has tires of a different size than the
s iz e in dicated on the vehicle placard or tire in­
flat ion pressure label, you should determine
the proper tir e inflation pressure for those
tires) .
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one o r more of your
tires is s ignificantly under-inflated. According­
l y, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as
soon as possible, and inflate them to the
proper pressure . Driving on a significantly un ­
der-inflated tire causes the tire to overheat
and can lead to tire fa ilure. Under-inflation al-
so reduces fuel effic iency and tire tread life, ..,.
