- Always make sure the forward-facing seat
has been designed and certified by its man­
ufacturer for use on a front seat with a
passenger front and side airbag.
-Always follow the manufacturer's instruc­
t ions provided with the child safety seat or
carrier.
-Always move the passenger seat into its
rearmost position in the seat's fore and aft
adjustment range, as far away from the air­
bag as possib le befo re installing the child
restraint. The backrest must be ad justed to
an upr ight position.
- Always make sure that the
PASSENGER AIR
BAG OFF
lig ht comes on and stays on all the
t ime whe never the ignition is switched on.
(D Tips
Always rep lace child rest raints that were in­
stalled in a vehicle dur ing a crash. Damage to
a child rest rain t that is not v is ible could cause
it to fail in another collision situ ation.
Advanced front airbag system and children
Your veh icle is equipped with an "Advanced Air ­
bag System" in compliance with U nited States
Federal Motor Vehicle Safety Standard (FMVSS)
208 as applicable at the time your vehicle was
manufactured.
The Advanced Airbag system in your ve hicle has
been ce rtified to meet the " low-risk" requ ire­
ments for 3 -and 6-year-o ld children on the pas­
senger side and small adults on the driver side.
The low risk deployment criteria are intended to
reduce the r isk of injury throug h interaction with
the airbag t hat can occur, for examp le, by being
too close to the s teer ing wheel and instrumen t
p a nel when the a irbag inflates. In ad di tion, the
sys tem has been cert ified to comply with the
"s uppression" requirements of the Safety Stand ­
ard, to turn off the front airbag for infa nts up to
12 months who are restra ined on the front pas­
se nger seat in chi ld restraints that are listed in
the Standard.
Even tho ugh yo ur vehicle is equi pped with an Ad­
vanced A irbag system, a ch ild should always ride
Child Sa fet y
in the seat properly restrained fo r its age and
size. The airbag on the passenger side makes the
f ront seat a potent ia lly dange ro us place for a
c h ild to ride. The front seat is not the safest place
for a ch ild in a forward-fac ing ch ild safety seat. It
can be a very dangerous place for an infant or a
la rger child in a rearward-fac ing seat.
Advanced Airbags and the weight-sensing
mat in the front seat
T he Advance d Airbag System in you r vehicle de­
tects the presence of an infant or child in a child
rest raint on the front passenger seat using the
weight-sensing mat in the seat c ushion and the
sensor below the safety belt latch o n the front
passenger seat that measures the tension on the
safety belt.
The we ight-sensing mat measures total weight of
the child and the child safety seat and a ch ild
blanket on the front passenger seat. The we ight
o n the front passenger seat is related to the de­
s ign of the child rest raint a nd its "footpr int", t he
s iz e and s hape of the bottom of the c hild re­
str aint as i t si ts on the seat. The weight of a ch ild
restrain t and its "foo tpr in t" vary fo r different
ki nds of child res traints and fo r th e d iffe rent
models of the same kind of chi ld restraint offered
by chi ld restraint man ufact urers.
T he we igh t ranges for the individu al types, ma kes
and mode ls of chi ld res traints t hat the NHT SA
has spec ified in the Safety Standard toget her
with t he weig ht ranges of typica l infants and typ ­
ica l 1 year-old child have been stored in the con­
trol unit of the Advanced Airbag System. When a
c h ild restra int is being used on the front passen­
ger seat with a typical 1 year-old ch ild , the Ad­
vanced Airbag Syste m compa res the we ight
measu red by the we ight sens ing mat with the in­
f o rmat io n sto red in the e lec tronic con trol un it.
T he elec tronic cont ro l unit also reg iste rs the ten­
s io n on the front passenger safety belt. The ten­
s io n on the safety be lt fo r th e front passe nger

the safety belt for the front seat passenge r
measures the tension on the be lt . T he inp ut from
this sensor is then used w ith the weight to "de­
cide", whether there is a child restra int w ith a
t ypical 1 year-old child on the front passenger
seat and whether or not the airbag must be
turned off .
Child restraints and Advanced Airbags
Regardless of the chi ld restraint that you use,
make sure that it has been ce rtified to meet Un it ­
ed States Federal Motor Vehicle Safety Standards
and has been certified by its manufact urer for
use with an airbag. If in exceptional circ umstan­
ces yo u must use it on the front passenger seat,
caref ully read all of the information on child safe­
ty and Advanced Airbags and heed all of the ap­
plicable WARNINGS . Make certain that the child
restraint is correctly recognized by the we ight­
sensing mat ins ide the front passenger seat, that
the front passenger a irbag is tu rned off and that
the airbag status is a lways correctly signaled by
the
PASSENGER AIR BAG OFF light .
Many types and models of c hild restra ints have
been ava ilable ove r the years, new models a re in­
troduced regu larly incorporat ing new and im ­
p roved des igns and o lder models are taken out o f
p rod uction. Child rest raints are not standardized.
Chi ld restraints of the same type typically have
d ifferent weights and sizes and different 'foot­
prints,' the si ze and shape of the bottom of the
child restraint that sits on the seat, when they
are installed on a veh icle seat . These differences
make it v irtually impossible to certify compliance
with the requ irements for advanced ai rbags with
each and eve ry child rest raint that has ever been
sold in the past or will be sold ove r the course of
the useful life of your vehicle.
For this reason, the United States Nat iona l H igh­
way Traffic Safety Admin istration has p ublished a
lis t of specific type , makes and models o f chi ld
restraints that m ust be used to certify comp li­
ance of the Advanced Airbag System in your vehi­
cle with the suppression requirements of Federal Motor Vehicle Safety Standard 208. These chi ld
restraints are:

Snow chain s
Where tire cha ins are mandatory on certai n
roads, this normally a lso applies to vehicles with
all-wheel drive
¢ page 194, Snow chains .
Replacing wheels /tires
Vehicles w ith all-whee l drive must a lways have
tires of the same si ze. Also avoid t ires with differ ­
ent tread depths. Fo r deta ils see page
¢ page 186, New tires and replacing tires and
wheels.
Off-Road driving?
Your Audi does not have enough ground clear­
an ce to be used as an off-road veh icle.
It is there ­
fore best to avo id rough tracks and uneven ter­
rain as m uch as possible . A lso re fer to
¢ page 142.
A WARNING
-Always adjust your driving to road and traf­
fic cond itions. Do not let the extra safety af·
forded by all-whee l dr ive tempt you into tak­
ing extra r isks .
- Althoug h the all-wheel dr ive is very effec­
t ive, always remember that brak ing capac ity
is limited by tire tract ion. You should there­
fore not dr ive at excessive speeds on icy o r
slippery road su rfaces.
- On wet road su rfaces, be careful not to drive
too fast because th e front whee ls cou ld be­
gin to slide o n top of the water (aquap lan­
ing).
If t his s hou ld o cc ur , you will have no
warning from a sudde n increase in engine
speed as with a front -whee l drive vehicle .
Always drive at speeds which are s uited to
the road conditions. -ris k of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for starting the engine.
If a vehicle w it h a conventional energy system is
not drive n for a long per iod of t ime, the battery
is discharged by idli ng cur rent consumers (e.g .
140
immob ili zer). In certain c ircumstances it can re ­
s ul t in the re being insufficient energy available to
start the eng ine.
I ntelligent energy managemen t in your veh icle
hand les the d istribution of electrical energy .
Starting ability is markedly improved and the life
of the battery is extended.
B asically, energy managemen t consis ts of
bat­
tery diagnosi s, idling current management
and
dynamic energy management.
Battery diagnosis
Battery diagnosis continuously dete rm ines t he
st ate of the bat tery. Sensors dete rm ine battery
vo ltage, batte ry cur rent and battery tempera­
ture . This de termines the current state of cha rge
and t he power of the battery.
Idling current management
Idli ng cur ren t management reduces energy con­
sumption whi le the vehicle is s tanding. W it h the
i gni tion swi tched off, it contro ls the energy s up­
ply to the various electrical components . Data
from battery d iagnosis is considered.
Depend ing o n the ba tte ry's st ate of ch arge, indi­
vidual consumers are gradua lly tur ned o ff to pre­
vent excessive discharge of the batte ry and thus
maintain starting capa bility .
Dynamic energy management
While t he ve hicle is being driven, dynamic e ne rgy
m anag eme nt dis trib utes the energy ge nerated
accord ing to the needs of the individ ua l compo ­
nents . It regu lates consumption, so that more
e lectrica l ene rgy is not be ing used than is being
generated and ens ures an optima l state of
c h arge for the battery.
(D Tips
- But even ene rgy management cannot neg­
ate the lim its of physics. Cons ider that the
p ower and life of a batte ry are lim ited.
- If start ing ability is threa tened, you are in ­
formed by a warning ¢

Vehicle care and cleaning General information
Regular, proper care helps to maintain your vehi ­
cle's value.
It can a lso be a req uirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The required cleaning and care products can be
obtained from your authorized Audi dea ler or a
qualified workshop. Read and follow the instruc­
tions for use on the packaging.
A WARNING
-Us ing clean ing and care products incorrectly
can be dangerous to your health.
- Always store cleaning and care products out
of reach of children to reduce the r isk of poi­
soning.
@ For the sake of the environment
- Preferably use environmentally-friendly products when buying cleaning agents.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer deposits remain on the vehicle, the
more the surface can be damaged. High tempera­
tures such as those caused by sunlight increase
the damaging effect .
Before washing, wet heavy deposits with plenty
of water.
Stubborn depos its such as bird droppings or tree
sap are best removed with plenty of water and a
microfiber cloth .
A lso, was h the underside of your vehicle once
road salt stops being used for the season.
Pressure washers
When washing your veh icles w ith a pressure
washer, always follow the operating instructions
"' provided with the pressure washer. This is espe-
r--
~ cially important in regard to the pressure and
; spraying distance . Do not aim the spray directly
~ at seals on side windows, doors, the engine com -,.... Vehicle care and cleaning
partment lid, the front lid
or the convertible top
or at tires, rubber hoses, insulating material
orsensors* or camera lenses *. Keep a distance of
at least 16 inches (40 cm).
Do not remove snow and ice with a pressure
washer .
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above 140 °F
(60 °().
Automatic car washes
Spray off the veh icle before washing.
Make sure that the windows are closed and the
windshield wipers are off. Follow instructions
from the car wash operator, especially if there are
accessor ies attached to your vehicle .
If possible, use car washes that do not have
brushes .
Only use car washes where the vehicle remains
stationary and the washing equipment moves
around t he vehic le when washing and drying. Car
washes that move the vehicle through the car
wash using a chain are not recommended.
Washing by hand
Clean the vehicle starting from the top and work­
ing down using a soft sponge or cleaning brush.
Use solvent-free cleaning prod ucts .
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi ­
cle. Insects, grease spots and fingerprints are
best removed with a spec ia l cleaner for matte
finish paint.
Apply the prod uct using a microfiber cloth . To
avo id damaging the paint surface, do not use too
much pressure.
Rinse the vehicle thoroughly with water. Then
c lean using a neutral shampoo and a soft micro­
fiber cloth.
Rinse the vehi cle thoroughly again and let it air
dry. Remove any water residue using a sham my . .,.

Vehicle care and cleaning
A WARNING
-Only wash the vehicle when the ignition is
off and follow the instructions from the car
wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect
may be delayed due to moisture on the
brake rotors or ice in the winter. The bra kes
must be dried first with a few caref ul brake
applications .
@ Note
-If you wash the ve hicle in an au tomatic car
wash, you must retract the extend able rear
spoi ler * if necessary, and fold the exterior
mirrors in to reduce the risk of damage .
Power folding exterior mirrors* must only
be fo lded in and out using the power folding
funct ion.
- To prevent paint damage, do not wash the
vehicle in direct sunlight.
- To red uce the risk of damage, do not wash
the power top with a pressure washer. -
To reduce the risk of damage, do not wash
decorative decals * with a pressure washer.
- T o reduce the risk of damage to the surface,
do not use insect remov ing sponges, kitchen
sponges or similar items.
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polish ing agents or hard
wax.
- Never use car wash cycles that apply pro­
tective wax. It can destroy the matte fin­ ish effect .
- Do not place any stickers or magnet ic
signs on vehicle parts painted w ith matte
finish paint. The pa int could be damaged
when the stickers o r magnets are re­
moved.
- Do not wash the vehicle using cleaning
products that contain alcohol when the en­
gine is hot. This increases the risk of dam­
age to plastic components, such as cracking.
@ For the sake of the environment
Only wash the vehicle in facilities spec ial ly de­
signed for that purpose. This w ill reduce the
risk of dirty water contaminated with oil from
entering the sewer system .

We still recommend you check the coolant level
from time to time .
Coolant lo ss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cooling
system should be inspected immediately by your
author iz ed Audi dealer. It is not enough merely
to add coolant.
In a
s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheat ing.
A WARNING
- The cooling system is under pressure. Do
not open the cap of the coolant expans ion
tank when the engine is hot. You risk being
sca lded.
-
- The coolant add itive, and therefore the cool­
ant itself, is hazardous to health. Keep the
c oolant additive in the or igina l co ntainer out

It is a poison haz­
ard.
Ch eck ing and fillin g
(D Note
Do not add any type of radiator leak sea lant
to your vehicle's engine coolant . Add ing radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Veh icle Limited Warranty.

Tires a nd wh eels
Tire ply composition and
materials used
The number of plies indicates the
number of layers of rubber-coat­
ed fabric in the tire. In general,
the greater the number of plies,
the more weight a tire can sup­
port . Tire manufacturers also
must indicate the materials in the
tire, which include steel, nylon, polyester, and others .
Maximum Load Rating
This number indicates the maxi­
mum load in kilograms and

Replacing tires or rims on
vehicles equipped with tire pressure monitoring sy stem
The wheels on your vehicle are
equipped with a sensor which
constantly monitors the air pres ­
sure inside the tire, and then
transmits this information to the
tire pressure monitoring system.
If you are go ing to replace the
wheel rims on your vehic le, make
sure the new rims also have these
sensors. The sensors must be
compatible with the tire pressure monitoring system on your vehi­
cle.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then
the tire pressure monitoring sys­
tem will not work properly . In this
case, the tire pressure monitoring
system would not be able to mon­ itor the tire pressure or warn you
if it is necessary .
-The battery inside of the tire pressure sensor has a limited
service life.
-Always drive with the valve stem caps securely mounted . We rec­
ommend using factory installed ""
