Parking systems
General information
A ppl ies to vehicles: with rea r parking sys te m s/park in g
syste m plus/rearv iew camera
Depending on your vehicle's equipment, vari­
ous parking aids will help you when parking
and maneuvering.
The
rear parking system is an audible parking
aid that warns you of obstacles
behind the ve­
hicle
¢ page 115.
The parking system plus assists you when
parking by audibly and visually indicating ob­
jects detected
in front of and behind the vehi­
cle
¢ page 115.
The rearview camera shows the area behind
the vehicle in the MMI display . This display as­
sists you when you are cross or parallel park­
ing. The parking system plus functions are al­
so available
¢ page 116.
& WARNING
- Always look for traffic and check the area
around your vehicle by looking at it di­
rectly as well. The parking system cannot
replace the driver's attention. The driver
is always responsible when entering or
leaving a parking space and during simi­
lar maneuvers .
- Please note that some surfaces, such as
clothing, are not detected by the system.
- Sensors and cameras have blind spots in
which people and objects cannot be de­
tected . Be especially cautious of small
children and animals .
- Always pay attention to the area around
the vehicle -using the rearview mirror,
too.
- The sensors can be displaced by impacts
or damage to the radiator grille, bumper,
wheel housing and the underbody. The
parking systems may become impaired
as a result. Have your authorized Audi
dealer or qualified workshop check their
function. -
Make sure the sensors are not covered by
stickers, deposits or any other obstruc­
tions as it may impair the sensor func­
tion . For information on cleaning, refer
to ~
page 201 .
(D Note
- Some objects are not detected or dis­
played by the system under certain cir­
cumstances:
- Objects such as barrier chains, trailer
draw bars, vertical poles or fences
- Objects above the sensors such as wall
extensions
- Objects with specific surfaces or struc­
tures such as chain link fences or pow­
der snow
- If you continue driving closer to a low-ly­
ing object, it may disappear from the
sensor range. Note that you will no lon­
ger be warned about this obstacle.
- The sensors can be displaced by impacts
or damage to the radiator grille, bumper,
wheel housing and the underbody. The
parking system may become impaired as
a result. Have your authorized Audi deal­
er or qualified repair facility check their
function .
(D Tips
- The system may provide a warning even
though there are no obstacles in the cov­
erage area in some situations, such as:
- certain road surfaces or for long grass.
- external ultrasonic sources e.g. from
cleaning vehicles.
- heavy rain, snow, or thick vehicle ex­
haust.
- We recommend that you practice park­
ing in a traffic-free location or parking
lot to become familiar with the system.
When doing this, there should be good
light and weather conditions.
- You can change the volume and pitch of
the signals as well as the display

190 Smart T echnol ogy
Drive to an authorized Audi dea le r or qualified
repair facility immediately to have the ma l­
function corrected .
_& WARNING
Have the system malfunction repaired as
soon as possible by an authorized Audi
dealer or qualified repair facility, as th is in ­
creases the risk of an acc ident.
(D Tips
If the . or ,1:-ij indicator light on ly stays
on for a short time , you may continue driv­
ing .
ALL wheel drive
(quattro)
Appl ies to vehicles: wit h all whee l drive
In all wheel drive, all four wheels are pow ­
ered .
General information
In all wheel drive, the driving power is divided
between all four wheels. This happens auto­
mat ica lly depending on you r driv ing behavior
as we ll as the current road conditions. Re fer
to
¢ page 185, Electronic stabilization con ­
trol (ESC) .
The all wheel drive concept is designed for
h igh engine power . Yo ur vehicle is exception­
a lly powerful and has excellent driving charac ­
teristics bot h under normal driving conditions
and on snow and ice . A lways read and fo llow
safety precautions
c> & .
Wint er t ire s
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter
conditions . However, in winter we recommend
using winter or all season t ires on
all four
wheels, because this will improve the braking
effec t.
Snow cha in s
If there are snow chain laws, snow chains
must also be used on vehicles with a ll whee l
drive
c> page 241, Snow chains.
Replacing tire s
For vehicles with a ll wheel d rive, only wheels
with the same ro lling circumference should be
u sed. Avoid wheels with different tread
depths ¢
page 236 .
Offroad vehicle?
You r A udi is not a n offroad vehicle -there is
not enoug h ground clearance. For this reason ,
avoid difficu lt terrain. Refer to
c::> page 266.
A WARNING ~
- Also, in vehicles with a ll w heel drive,
adapt your driving sty le to the c urrent
road and traffic cond itions. Do not let
the increased safety provided tempt you into taking risks .
- The braking ability of your veh icle is lim­
ited to the traction of the wheels. In this
way, it is not different from a two wheel d rive vehicle . Do not be tempted to ac­
celerate to a high speed when the road is
slippe ry this inc reases the r is k of an acci­
dent.
- Note that o n wet s treets, the front
wheels ca n "hydrop lane " if driv ing at
speeds that are too high. Unlik e fron t
wheel drive vehicles, the engine does not rev higher sudden ly when the vehicle be­
g ins hydroplaning. For this reason, pay
attention to the road conditions regard­ less of your speed.
Energy management
The starting ability is optimized
The energy management system manages
the electrical energy distribution and optimiz­
es the availability of electrical energy for
starting the engine.
When a vehicle with a conventiona l energy
system is not d riven for a long time , the bat­
te ry is drained by equ ipment ( for example the
immobilizer) . In certain c ircumstances, there
cou ld may not be enough energy to start the
engine .
1J1-

The speed rating letter code (c::> page 228) is
on the side wall of the tire
c::> page 236.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­ imum speed . Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
t ires leading to an ac ciden t and se rious
pe rsonal in jury to you and yo ur passen­
ge rs .
A WARNING
Dr iv ing faster than the maximum speed
for which the winter tires on your vehicle
were designed can ca use tire fai lure in­
cl uding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
rep laced immed iate ly.
- Winter tires have maximum speed rat ing
that may be lower tha n your ve hicle's
maximum speed .
- Never drive faster than the speed for
w hich the winter or other tires installed
on your veh icle are rated .
A WARNING
Always adjust your d rivi ng to the road and
traffic conditions. Neve r let the good ac­
c eleration of the w inte r ti res an d all-whee l
drive temp t you in to taking extra r is k s . A l­
ways remember :
- When bra king, an a ll-wheel d rive vehicle
hand les in the s ame way as a front drive
vehicle.
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
@l For the sake of the environment
Use summe r tires w hen weathe r cond i­
tions permit. They are quieter, do not we ar
as quickly and red uce fue l cons umption.

Snow chains
Snow cha ins may be fitted only to the front
whee ls , a nd o nly to certa in ti re si zes. As k your
autho rized Aud i dea ler on whi ch tire sizes
snow chains can be used.
If you a re go ing to use snow cha ins, then you
mus t install t hem on the front whee ls a t
least.
T he snow chains must have low-p rofi le links
and must not be th ic ker than 0.53 inch
(13,S mm) , in cl ud ing t he lo ck.
Remove whee l cen ter covers and t rim discs
before putt ing snow cha ins on your veh icle
c::> (]) . For safety reasons cover caps must t hen
be fi tte d over the wheel bol ts. These are av ail­
able from autho rized Aud i dealers .
A WARNING ,..__
Using the wrong snow chains for your vehi ­
cle o r insta lling them incorrect ly can in ­
crease the risk of loss of contro l leading to
serious personal injury.
- Snow chains are available in different
sizes . Always make sure to follow the in­
structions prov ided by the snow chai n
manufacturer .
- When driving wit h snow cha ins neve r
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow c hains before driving o n
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con ­
tact with the whee l rim, ca n scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
t he pos ition of the snow chains afte r
dr iv ing a few yards and co rrect if neces­
sary. Follow the inst ru ct io ns from the
snow chain m anufacturer w hen do ing so. ..,.

24 2 T ire s and wheel s
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory installed rims . If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r=> page 270.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
c ont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­ er ly t igh tened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue fo r th e wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out w hen the veh i­
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torque wheel bolts diago­
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque w rench -preferably by an author­
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w it h low aspect
ra tio tires. These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and handling under a variety of d riving condi ­
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The n umera l represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
t iona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pressure. It is therefore important that low
a spect ratio tires are inflat ed to the specified
pre ssure and that the inflation pressure i s
regularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
m onth and always bef ore a long trip
r=> page 231, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be d amage d more
easily by impact w ith potholes, curbs, gull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.

impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the t ire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads), the pressure monitor ind i­
cator may be de layed.
- Ask your authorized dealer if run-flat
tires may be used on your vehicle. You ve­
hicle registrat ion becomes invalid if you
use these tires when not permitted .
Damage to your vehicle or accidents
c ou ld also resu lt.
(0 Tips
- The t ire pressure monitoring system can
also stop work ing when there is an ESC/
ABS malfunction.
- Using snow chains may result in a system malfunction .
- The t ires with the ident ificat ion "AO" or
"RO"¢ page 236 have been matched
with you r A udi tire p ressu re monito ring
system. We recommend that you use
these tires.
- The t ire pressure monitoring system can
on ly mon itor the t ire pressure of the
driving tires . C he ck the tire pressure of
the spare wheel in the luggage compart ­
ment so that if necessary it is ready for
