Audi side assist
-Improper reliance on the side assist system
can cause collisions and serious personal in­
jury:
- Never rely only on side assist when chang­
ing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles under
all conditions- danger of accident!
- Please note that side assist indicates there
are approaching vehicles, or vehicles in your blind spot, only after your vehicle has
reached a driving speed of at least 19 mph
(30 km/h).
- In certain situations, the system may not
function or its function may be limited. For
example:
- if vehicles are approaching or being left
behind very quickly . The display may not
turn on in time .
- in poor weather conditions such as heavy
rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface . Vehicles
in the adjacent lane may not be detected
because they are outside of the sensor
range.
(D Note
The sensors can be displaced by impacts or damage to the bumper, wheel housing and
underbody . This can affect the system . Have
your authorized Audi dealer or authorized
Audi Service Facility check their function.
(D Tips
-If the window glass in the driver's door or
front passenger's door has been tinted, the
display in the exterior mirror may be misin­
terpreted.

Safety belts
A WARNING
Always read and heed all WARNINGS and oth­
er important informat ion
c:> page 140 .
(D Tips
You can also adjust the height of the front
seats to change the position of the safety
belts.
Improperly worn safety belts
Incorrectly posit ioned safety belts can cause se­
vere injuries.
Wearing safety belts improperly can cause seri­
ous injury or death. Safety belts can only work
when they are correctly positioned on the body.
Improper seating positions reduce the effective­
ness of safety belts and will even increase the
risk of injury and death by moving the safety belt
to cr it ica l areas of the body . Improper seating
positions also increase the risk of serious injury
and death when an airbag deploys and strikes an
occupant who is not in the correct seating posi­
tion. A driver is responsible for the safety of all
vehicle occupants and especia lly for children.
Therefore:
... Never permit anyone to assume an incorrect
sitting position in the vehicle whi le traveling
c:> & .
A WARNING
Improperly worn safety belts increase the risk
of serious personal injury and death whenever
a vehicle is being used.
- Always make sure that all vehicle occupants
are correctly restrained and stay in a correct
seat ing pos ition whenever the veh icle is be­
ing used.
- Always read and heed all WARNINGS and
other important information

Belt tensioners
' How safety belt pretensioners work
In front, side and rear-end collisions above a
particular severity and in a rollover, safety belts
are tensioned automatically.
Rever sible safety belt tensioners
The safety belts on the front seats are equipped
with power reversible tensioners. The following
functions are available when the driver's/front
passenger 's safety belts are fastened:
- Automatic tensioners: at the start of a drive,
the safety belts automatically adjust to the
passenger after a certain time period or vehicle
speed. To switch the automatic tensioners off,
select the following in the MMI:
!CARI function
button
> Car systems > Vehicle settings >
Seats > Driver's seat or Passenger's seat > Au­
tomatic belt tensioner
> Off.
-In certa in driving situations , the safety belts
may tighten with a reve rsib le tensioning func­
tion
c:> page 187.
- Th e safety be lts may also tighten with this re-
vers ible tensioning funct ion in minor collisions.
Pyrotechnic safety belt pretensioners
The safety belts are equipped w ith safety belt
pretensioners . The system is activated by sensors
i n front, side and rear-end collisions of great se­
verity and in a rollover. This tightens the belt and
takes up belt slack
c:> .&. in Service and disposal of
safety belt pretensioner on page 145.
Taking up
the slack helps to reduce forward occupant
movement during a collision.
A WARNING
- It is possible for the pretensioners to deploy
incorrectly.
- The pyrotechnic system can only provide protection for one collision. If the pyrotech­
nic pretens ioners deploy, the pretensioning
system must be replaced.
(1) Tips
The pyrotechnic safety belt pretensioners can
only deploy once. ..,_

-The safety belt pretensioners do not dep loy
in minor fronta l, side and rear -end co lli­
s ions .
- A fine dust is released when the pyrotechnic
safety belt pretensioners deploy. This is nor­
mal and is not caused by a fire in the vehi­
cle.
- The relevant safety requirements must be
observed when the veh icle or components
of the system are scrapped. A qualified
dealersh ip is familiar w ith these regulations
and will be pleased to pass on the informa­
tion to you .
- Be sure to observe all safety, environmental
and other regu lations if the veh icle or indi­
v idual parts of the system, particularly the
safety be lt o r airbag, a re to be disposed . We
recommend yo u have your author ized Audi
dealer perform this serv ice for you.
Service and disposal of safety belt preten­
sioner
The safety belt pretens ioners are parts of the
safety belts on your Audi. Insta lling, removing,
servic ing or repa iring of belt p retensioners can
damage the safety belt system and prevent it
from wor king cor rect ly in a collision .
T here are some important things you have to
know to make sure that the effectiveness of the
sys tem w ill not be impaired and that discarded
components do not cause injury or pollute the
e nvironment.
_& WARNING
-
Improper care, serv icing and repa ir proce­
dures can increase the risk o f personal injury
and death by preventing a safety be lt preten­
sioner from activating when needed or acti­
vating it unexpectedly :
- The be lt pretensioner system can be activat­
ed only once . If belt pretensioners have
been activated, the system must be re­
placed .
- Never repair, adjust, or change any parts of
the safety belt system.
- Safety belt systems including safety belt
pretens ioners cannot be repaired. Specia l
Safet y be lts
procedures are required fo r removal, instal­
lation and disposal of this system.
- For any wo rk on the safety belt system, we
strong ly recommend that you see yo ur au­
thor ized Audi dealer or qualified techn ician
who has an Audi approved repa ir manual,
tra ining and special equipment necessary .

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
cha nge the way that the Advanced Airbag System
pe rforms in a crash. For example, using tire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, chang ing the stiffness of the suspens ion,
including the spr ings, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the force levels measured by
the sensors and preven t the airbag from deploy­
ing when it should .
A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced A irbag performance and in­
crease the risk of serious personal injury in a
crash.
- Never install suspension components that do not have the same performance charac­
teristics as the components originally insta l­
led on your veh icle .
- Never use tire-rim comb inations that have
not been approved by Audi.
160
A WARNING
Items stored between the safety belt buckle
and the center console can cause the sensors in the buckle to send the wrong information
to the electronic contro l module and prevent
the Advanced A irbag System from wo rking
p roperly.
- Always make sure that noth ing can inte rfe re
w ith the safety belt buckles and that they
are not obst ructed.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to properly restrained front seat
occupants.
Fig. 167 Driver's kn ee ai rbag
The driver knee airbag is in the inst rument panel
u nderneath the s teer ing whee l
~ fig. 16 7, the
airbag fo r the passenger is at about the same
height in the instrument panel underneath the
glove compartment.
The knee airbag offers add itiona l protection to
the d river's and passenge r's knees and uppe r and
l ower thigh areas and supp lements the protec ­
tion prov ided by the safety belts .
If the front airbags deploy, the knee airbags a lso
deploy in frontal coll is ions when the deployment
th reshold stored in the control unit is met

pollutants in the exha ust gas before they are re ­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the l ife of the catalytic converter and
proper functioning of the engine.
A WARNING
T he temperature of the exha ust system is
high, both when driving and after stopping
the engine.
-
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exha ust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or rustproofing on or near the exhaust mani­
fold, exhaust p ipes, catalytic converter or
heat sh ields. During dr iv ing, the substance
used fo r undercoating could overheat and
ca use a fire.
(D Note
- Be aware that just one tank filling with
le aded fuel will already ser iously degrade
the performance of the catalytic co nverter .
- Do not exceed the correct eng ine oil level
<=;> page 225.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this cou ld cause the
cataly tic converte r to overheat.
- Do not sw itch off the ignition while the veh i­
cle is moving.
- Do not continue to operate your vehicle un­
der these cond it ions, as otherwise fue l can
r each the catalyti c converte r. This cou ld re­
su lt in overheating of the conve rter, req uir­
i ng its replacement.
- T o assure efficient oper ation of the Emis­
s ion Control Sys tem:
- Have your veh icle maintained properly and
in accordance with the service recommen­
dations in your Warranty

-Lack of proper ma intenance as well as im ­
proper use of the vehicle wi ll impair the
funct ion o f the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emiss ion Control System is op ­
erating properly, the exhaust gas can have a
su lfu r-li ke exhaust gas sme ll under some op­
erating states. Th is depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or fi lling the tank
with lead-free super g rade gasoline.
Diesel particulate filter
App lies to: vehicles with diese l engine
The diesel particulate filter filters nearly all of
the soot part icles out of the exhaus t. The filte r
clea ns itself automat ica lly unde r no rma l dr iv ing
cond it ions. If the fil ter canno t clean i tself (fo r ex­
amp le, because yo u are on ly driving short distan­
ces), the filter becomes clogged with soot and
the

A WARNING
- Do not park your vehicle over flammable
materials such as grass or leaves because
the high temperature of the diesel particu­
la te filte r could sta rt a fi re.
-
- Do not apply an underbody protectant in the
exhaust system area or a fire could start.
Shutting down vehicle
If you would like your vehicle to remain inopera­
tive for a longer period of time, contact an Audi
or other spec ia lized dealer . They can adv ise you
o n necessary p recautions e .g. corros ion preven­
tion, ma intenance and storage . Pay attention to
additional informat ion concer ning t he battery.
Refer to
<::;> page 2 31.

Driving and th e en vironm ent
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
.,. Try and keep well below your car's maximum
speed .
Accelerating gent ly reduces fue l consumption,
engine wear, and does not disturb the environ­ ment.
Fue l consumption, exhaust emissions and engine
noise increase d isproportionately at high speeds.
If you drive at approximately three quarters of
top speed, fuel consumption will be reduced by
one half. Never drive faster than the posted
speed limit and weather conditions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
.,. Shut the engine off when you are not driv ing
the vehicle.
.,. Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automatically reduced for
veh icles with the Start-Stop-System*. It is effi­
cient to switch off the eng ine in vehicles without
the Start -Stop -System when stopped at ra ilroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is bu rned by starting the engine aga in.
It takes a long t ime for the engine to warm up
fu lly when it is running at idle . However, wear
and noxio us em iss ions are espec ially high when
the engine is wa rm ing up. So you sho uld drive
away as soon as you start the engine a nd avoid
running at high rpms while the engine is still
warming up.
(D Note
Do not leave engine idling unattended a fter
starting . If warn ing lights should come on to
indicate improper operation, they wou ld go
unheeded. Extended idling a lso produces
heat, wh ich co uld result in overheat ing or
200
other damage to the vehicle or othe r proper ­
ty.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
.,. Have you r veh icle serviced at regula r interva ls.
By hav ing your veh icle regularly serv iced by an
Audi dealer he lps to ensure that it runs p roperly
and e conomi cally. The cond ition of you r vehicle
not only affects its safety and ab ility to hold its
val ue, it also affects
fuel con sumption .
Check your oil each t ime you fill your tank .
The amount of oi l used is related to engine load
and speed .
It is normal for the oil consumption of a new en­
gine to reach its lowest value after a certain mile­
age has been driven .
You must drive your vehicle about 3,000 mi les
(5,000 kilometers) before you can properly as­
sess oil consumpt ion.
This also app lies to fue l consumption and engine
output .
(D Note
-Have your ve hicle ma intained properly and
in accordance with the se rvice recommenda ­
tions in your Warranty
& M aintenance book­
let. Lack of proper maintenance as we ll as
improper use of the veh icle w ill impair the
function of the em ission control system and
cou ld lead to damage .
- Do not alter or remove any component of
the Emission Contro l System u nless ap­
proved by the man ufacturer.
- Do not alter or remove any device, such as
heat shields, switches, ign ition w ires,
valves, which are designed to protect your
vehicle's Emission Contro l System and other
impo rtant ve hicle compone nts.

adjustment is more likely to be made in time .
(D Note
-Me thanol f uels which do not mee t these re­
quirements may ca use corros ion and dam­
age to plastic and rubber components in the
fuel system .
- Do not use fuels that fai l to meet the speci­
fied criter ia in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
ficat ions, ask your service station or its fuel
supplier.
- Do not use fuel for which the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
- If you experience a loss of fue l economy or
driveability and performance prob lems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many au to manufactur ­
ers is carbon deposit build- up caused by the type
of gasoline yo u use.
A lthough gasoline grades d iffer from one manu­
f a cturer to ano ther, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
pa rts, such as fue l injectors and intake valves . Al ­
though most gaso line brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Aud i recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Fuel and R efueling
After an extended period o f using inadeq uate
fuels, carbon deposit bui ld-ups can rob your en­
gine o f peak performance.
(D Note
Damage or ma lf u nction due to poo r fue l qual ­
ity is not covered by the A udi New Vehicle
Limited Warranty .
Diesel fuel
Applies to: vehicles with diesel engine
Always use ULSD (Ultra Low Sulfur Diesel) No. 2 .
The ULSD No . 2 meets the ASTM 0975.
Diesel f uel w it h concen tratio ns of b iod iesel h igh­
er than 5 % such as Bl 1, B20 or BlOO are strict ly
prohibited .
Se rvice station fuel p umps are labe led with the
correct f uel i nfo rmat ion for e asy recog nition by
the user.
If the d iesel f ue l pump is no t labeled
ask the station operator what fuel is being dis­
pensed before fil ling up your vehicle .
UL SD No . 2 m ay not be available ou tside the USA
and Canada . Be su re to check befo re t raveling to
other countries .
UL SD No . 2 c an become thic ke r i n ve ry cold tem­
peratures, and this can imp air the engine's s tart ­
ing and running. Depend ing on the sea son, gas
stations provide ULSD No . 2 that flows better in
cold temperatures so that you can continue oper ­
at ing your vehicle as usual.
@ Note
- Your vehicle's diese l engine was designed
sole ly for use with ULSD No . 2 . Therefo re,
neve r use gasoline, heating oil, other fuels
or flow improvers. These contain substances
that will severely damage the fuel system
and the engine . Such damage will not be
