198 Intelligent technology
Dynamic ste ering *
On vehicles with dynamic stee ring* , ES C helps
stabilize the st eering in critical s ituations .
Selective wh eel torque c ontrol
The selective whee l torque control operates
when dr iv ing through curves . T he front wheel
on the inside of the curve or both wheels on
the inside of the curv e are braked selective ly
as needed. This m inimizes sliding in the front
wheels and allows for more pr ecise driving
through curves . T he system may not act ivate
when driving in wet or snowy cond itions .
A WARNING
-ESC, ABS, ASR, EDL dynamic steering"
and the se lective wheel torque control
cannot overcome the laws of physics .
Th is is especially important on slippery
or wet roads.
If the systems begin act ing
to stabilize yo ur vehicle , you sho uld im­
med iately change your speed to ma tch
the road and traffic condit ions. Do not
let the increased safety provided by
these systems tempt you to take risks. Do ing so wi ll increase the risk of a loss of
vehicle control, collision and serious per­
sonal injuries .
- Always adapt your speed to road, traff ic
and weather condit ions. The risk of Los-
ing cont ro l of the veh icle increases when
Switching on/off
-
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead . ESC, ABS, the brake ass ist sys­
tem, ASR, ED L, dynam ic steering* and
the selective whe el torque cont ro l can­
not p revent collisions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheel s can spin eve n w ith
these assistance sys tems t hat can not al ­
ways he lp to red uce the risk of loss of ve­
hicle control.
(0 Tips
- ABS and ASR only work correctly when
all four whee ls are equipped wi th identi ­
cal tires . Different tire sizes can lead to a
reduction in engine powe r.
- Yo u may hear noises when the systems
described are working .
-If the ind icator light&] or llB (USA
mode ls)/ [iJ (Canada models) appears,
there may be a malfunction

-When installing a factory-supplied roof
rack system on the roof railing, the ESC
w ill adapt itse lf to a different center of
gravity.
ESC turn s on automa tically when you star t the engine .

iT-ij Dynamic steering: System fault! You can
cont inue driving
If the indicator light turns on and the mes­
sage appears, the steer ing may be more diffi­
cult to move or more sensitive than usual. The
steering may also be at an angle when driving
straight.
Drive slow ly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected .
iT-ij Dynamic steering: Initializing
Audi drive select*: if the indicator light blinks
and the driver message appears, the dynamic
steer ing* is reinitialized. Once you sta rt the
engine after this is finished, the steering
wheel will be easy to move. Re-ini tialization
might be necessary if the steering wheel was
moved hard to the left and right while the ve­
h icle was not moving . The display turns off if
the initiali zation was successful.
- If the . or
tTij indicator light on ly stays
on for a short time, you may continue
driving.
- The dynamic steering* stability systems

Driving with your
quattro
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-wheel dr ive, power is distributed to
all four wheels. This happens automatically
depending on your driving sty le and the road
conditions at the time . See also ¢
page 197.
A center different ial distr ibutes the dr iv ing
power var iably to the front and rear axle . It
works together with se lective wheel torque control, which activates when driving through
curves
r=:>
page 198.
The all-wheel drive concept is designed for
high eng ine power. Your veh icle is except ion ­
ally powerfu l and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice . Always read and follow
safety precaut ions r=;,
,&.
Winter tires
When driving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing : these tires must be mounted on
all four
wheels.
See also r=;, page 262, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also app lies to veh icles
with all-wheel driver=;,
page 263, Snow
chains .
Replacing wheels/tires
Vehicles with a ll-wheel drive must always
have tires of the same size. A lso avoid tires
with different tread depths. For deta ils see
page
r=;, page 2 SB, New tires and replacing
tires and wheels.
A WARNING
-Always adjust your dr iv ing to road and traf-
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning). If this should occur, you
will have no warning from a sudden in­ crease in eng ine speed as w ith a front­
wheel drive veh icle. Always drive at

Speed rating (letter code)
means the speed at wh ic h a tir e is des igned to
be d riven for extended per io d s of t ime. The
ratings range from 93 mph (150 km/h) to
186 mph (298 km/h) ¢
page 259 . You may
not find this in format ion on all tires because
it is not required by law.
The speed rating letter code, w here a pplica­

Uniform Tire Quality Grading
is a tire i nfo rmation system developed by the
United States Nat io nal Highway Traffic Safety
Admin istration (N HTSA) that is designed to
h e lp buye rs make re lative compa risons among
tires. The UT QG i s no t a safety r ating and no t a
g uar antee that a t ire will las t fo r a presc ribed

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correc t tire pressure and driv ­
ing style .

Tread Wear Indicator (TWI)
The o rigina l tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::;, fig. 207 running across the tread . Depend­
ing on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the t ire s idewa ll (for example " TWI" or other
symbols) indicate the positions of the tread
wear ind icators. Wo rn t ires must be r ep laced .
Tires and wheels 25 7

c::;, .&. .
Tire pressure
Incor rect tire press ure ca uses premature wear
and can c ause sudden tire blow-out. For this
reason , tire pressure m ust be checked at least
once a month
c::;, page 2 53.
Driving style
Driving fast around curves, h eavy acce le rat ion
and har d bra king increase tire wear .
Rotating tires for more even wear
For all four tires on your ve hicle to have the
same service life, we recommend that the
front and rear t ires a re rotated according to
the tire manufact urer's suggested tire ro ta­
tion intervals. Please remembe r the follow­
ing:
- Tire rotation intervals may differ from the
veh icle service inte rva ls o utlined in your
Ma intenance and Warranty Boo klet .
- The longer one tire is used in one location
on the vehi cle, the more it wears at cer tain
points ; the refore, we recommend that you
follow t he tire manu fact urer's suggested
tire rotation intervals .
- Ve hicl es w ith front-wheel dr ive exper ience
more tread wear on the front w heels com­
pared to a ll-wheel drive (quattro) .
- Please rot ate tires as shown
c::;, fig . 208.
- Extra care mus t be taken whe n rota ting di-
rection-spec ific tires
c::;, page 277 .
Wheel balancing
The wheels on new veh icles are balanced .
However, various s ituations during eve ryday
driv ing ca n cause them to become unba l­
anced, re su lting in vib rat io ns you ca n usually
feel t hrough the s teer ing whee l.
Unbalanced wheels must be rebalanced to
avo id excessive wear on steering, s uspension
and t ires. A whee l m ust also be reba la n ced
whe n a new tire is insta lled.
)J,,-

-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
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.
Tires and wheels 261
@ 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 258,
fig. 209.
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 (1 1/2) times as well on the
government course as a tire graded 100. •

26 2 T ire s and wheel s
The relat ive performance of tires depends
upon the actua l conditions of their use, how ­
ever, and may depart sign ificantly from the
norm due to va riat ions in dr iving habits, serv­
ice practices and differences in road character­
istics and climate.
Tr action
The traction grades , from highest to lowest,
are AA, A, Band
C. Those g rades represent the
tire's ability to stop on wet pavement as measured under controlled cond itions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢.&, .
Temperature
The tempera ture grades are A (the h ighest),
B, and
C, representing the tire's resistance to
the generat ion of heat and its abi lity to dissi ­
pate heat when tested under controlled cond i­
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden ti re fa il ur e~ .&, .
The grade
C corresponds to a level of perform ­
ance which all passenger ca r tires must meet
u nder the Federa l Moto r Veh icle Safety Stand­
a rd No.
1 09. Grades Band A represent higher
l eve ls of performance on t he laboratory test
wheel than the minimum required by law .
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering , hydroplan ing or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es­
tablished for a t ire that is properly inflated
and not overloaded . Excessive speed, un­
derinflation, or excessive loading, eithe r
-
separately or in combination, can ca use
heat bui ldup and possib le tire failure .
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F ( 7 °C) we recommend changing to winter
tires.
In some heavy snow areas , local governments
may require true winter or "snow" tires, those
with very deeply cut tread . These tires should
only be used in pairs and be installed on all
four wheels . Make sure you purchase snow
tires that are the same s ize and construction
type as the othe r tires on your vehicle .
Your vehicle is equipped with all-wheel drive,
th is will improve traction during winter driv ­
i ng, even with the standa rd t ires. However, we
strong ly recommend that you always equip all
four wheels on you r vehicle wi th cor rectly fit­
ted win ter tires o r all -season tires, when win­
te r road cond itions are expected . This also im­
proves the vehicle's braking performance and
reduces stopping distances.
Summe r tires provide less grip on i ce and
snow.
Winter tires (snow tires) must always be fitted on all four whee ls .
Ask your author ized Audi dealer or qualified
workshop for permitted
winter tir e siz es. Use
on ly rad ial winter t ires .
Winter tires lose their effectiveness when the
tread is worn down to a depth of
O .15 7 inch
(4 mm).
Only drive w ith w inter t ires under winter con ­
ditions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7
°() .
If you have a flat ti re, see notes on spare
whee l
¢page 258.
Please a lways remember that winter tires may
have a lower speed rating than the tires origi-
nally installed on your vehicle at the time it .,.

266 Tire s and wheels
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from funct ioning
properly . Always check the TPMS malfunct ion
tellta le after replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
N
I
Fig. 210 Display: underinflation warning
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, th is is indicated in the instru­
ment cluster w ith a
IE warning symbol and a
message
¢fig . 210. The dr iver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
the
! SET ! button. If on ly one tire is affected,
the display will indicate its position.
The tire pressure monitoring system must be
reset via radio or MMI * each time the pres­
sures are adjusted (e. g . when switching be ­
tween partia l and full load pressure) or after
changing or replacing a tire on your vehicle
¢
page 267. The TPMS indicator only moni­
tors the tire pressure that you have prev iously stored
. You can find the recommended tire
pressures for your vehicle on the label on driv­
er's side B-pillar ¢
page 251.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tir e pressure in one or more tires is too
low,
- the tir e has structural damage,
- the tir e pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset

If@m appears after switching the ignition on
or while dr iving and the
IE indicator light in
the instrume nt cluster blink s for app rox i­
mately one minute and then stays on, there is
a system malfunction.
Attempt to store the correct tire pressure
¢
page 267 . If the indicator light does not
tu rn
off or if it turns on shortly thereafter, im­
mediately drive you r vehicle to an authorized
A udi dealer or authorized repair facility to
have the malfunction corrected.
A WARNING
=
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your tires is sign ificant ly under­
inflated. Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres­
sure as ind icated on the vehicle's tire
p ressu re lab el¢
page 251. Driving on a
significantly under-inflated tire causes

the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi­
cator may be delayed.
-Ask your authorized Audi dealer if run­ flat tires may be used on your vehicle .
Your vehicle registration becomes invalid if you use these tires when not permit­
ted. Damage to your vehicle or accidents
could also result.
@ Tips
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with the "AO" or "RO" identification on the
tire sidewall¢
page 258. We recom­
mend using these tires.
Reset tire pressure monitoring system
Applies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
radio or MMI* .
.,. Before resetting the TPMS, the current pres­
sures of all four tires must correspond to
the specified values. Adjust the tire pressure and reset the pressure in the tire pressure
monitoring system according to the load
you are carrying
