General notes
Always wear safety belts!
Wearing safe ty bel ts correctly saves lives!
This chapter exp lains why safety be lts are nec ­
essary, how they work and how to adjust and
wear them correctly .
.. Read a ll the information that fo llows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of ser ious
personal in jury and death .
- Safety belts are the sing le most effective
means avai lab le to reduce the risk of se­
r ious injury and dea th in a utomob ile acci­
dents . For your protection and that of
yo ur passenge rs, always co rrectly wear
safety belts when the vehicle is moving .
- Pregnant women, injured, or physically
im paired perso ns m ust also use safety
belts . Lik e all veh icle occup ants, they are
more like ly to be ser iously injured if they
do not wea r safety be lts . The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions: two in the front and three in the rear. Each
seating position has a safety belt.
A WARNING
Not wea ring safety belts or weari ng them
improp erly increases the risk of ser ious
pe rsonal i njury and deat h.
- Never st rap more than one pe rson, in­
cl uding small ch ild ren, into any belt.
It is
e speci ally dange rous to pla ce a safety
belt over a child s itting on yo ur lap.
- N ever le t mo re people ride in the ve hicl e
than there are s afe ty be lts avail able. -
Be s ure everyone riding in the vehicle is
properly restrained w ith a separate safe ­
ty belt or child restra int.

150 Airbag sys te m
If the front passenger airbag is turned off, the
PASSENGER AIR BAG OFF light comes on in
the instrument cluster and stays on.
I f the front passenger airbag deploys, the
F ederal Standard requires the airbag to meet
the " low risk" deployment criteria to reduce
the r isk of injury through interaction with the
a irbag. "Low risk" deployment occurs in those
crashes that take place at lower decelerations
as defined in the electronic control unit
c::> page 160, PASSENGER AIR BAG OFF light.
A lways remember, a chi ld seat or infant carri­
er installed on the front seat may be struck
and knocked out of position by the rap idly in ­
flating passenger's a irbag in a frontal colli­
sion . The airbag could greatly reduce the ef­
fectiveness of the ch ild restraint and even se­
rio usly inju re the child during inflat ion.
For this reason, and because the back seat is
the safest place for chi ldren - when properly
restra ined accord ing to their age and size - we
strongly recommend that children always sit in the back seat
c::> page 173, Child Safety.
_& WARNING
-
A child in a rearward -facing child seat in ­
stalled on the front passenger seat will be
seriously injured and can be killed if the
front airbag inflates - even with an Ad­
vanced Airbag System.
- The inflating a irbag will hit the child seat
or infant carrier with great force and w ill
smash the ch ild seat and child against
the backrest, center armrest, door or roof.
- Always install rear-facing child seats on the rear seat.
- If you must install a rearward facing
child seat on the front passenge r seat
because of exceptiona l circumstances
and the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install the rear-f acing chi ld seat in a
rear seating position and have the ai rbag
system inspected by your Aud i dealer. -
Forward-facing child seats installed on
the front passenger's seat may interfere
with the deployment of the a irbag and
cause serious persona l injury to the
child.
_& WARNING
-If, i n except ional circumstances, you must
i nsta ll a forward-facing child restraint on
the front passenge r's sea t:
- Always make sure the forward-facing
seat has been designed and certified by
its manufacture r fo r use on a fron t seat
with a passenger fron t and s ide a irbag.
- Never p ut the fo rward -facing child re­
s tra int up against or very near the instru­
men t panel.
- Always move the passenge r seat into its
rearmost pos ition in the seat's fore and
aft ad justment range, as fa r away from
the airbag as possible before installing
the forward-facing ch ild restra int . The
backrest must be ad justed to an upright
position.
-Make sure that the PASSENGER AIR BAG
OFF
li ght comes on and stays on all the
time whenever the ignition is switched on .
_& WARNING
-To reduce the risk of serious injury, make
sure that the
PASSENGER AIR BAG OFF
light w ill be displayed whenever a child re­
straint is installed on the front passenger
seat and the ignition is sw itche d on .
- If the
PASSENGER AIR BAG OFF light
does not s tay on, perform the checks de­
scribed
<> page 159, Monitoring the Ad­
vanced Airbag System.
- Ta ke the chi ld restraint off the front pas­
senger sea t and install it prope rly at one
of the rear seat positions i f the
PASSEN­
GER AIR BAG OFF
light does not stay on.
- Have the airbag system inspected by
your Aud i dea ler immediately.

backrest must be adjusted to an upri ght
posit ion.
- Always make sure that t here is nothing
on the front passenger seat that will
cause the capacitive passenger detection
system in the seat to s ignal to the A irbag
System that the seat is occupied by a person when it is not, or to signal that it
is occupied by som eone who is heavier
than t he pe rson actually s itting on the
seat. The presence of additiona l obje cts
cou ld cause the passenger front airbag
to be t urned on when it sho uld be off, or
cou ld cause t he airbag to work in a way
that is different from the way it wou ld
have worked without the object on the
seat.
- Make sure that the
PASSENGER AIR BAG
OFF
light comes on and stays on all the
t ime whenever the ignition is switc hed
on.
Advanced Airbag System components
The front passenger seat in your vehicle has a
l ot of very important parts of the Advanced
A irbag System in it. These parts incl ude the
capac itive passenger de te ct ion sys tem, wir­
ing, b racke ts, and more . The cont ro l uni t
monitors the system o n the front passenger
seat when the ign ition is switched on and
turns the airbag indicator light on when a
malfunct ion in the one of the system compo­
nents is detected ¢
page 160. Because the
fro nt passenge r seat contains important parts
of the Advanced Airbag System, you must
take care to p revent it from bei ng damaged.
D amage to the seat may preven t the Ad ­
vanced A irbag System for the front passenger
seat from doing its job in a crash .
The front Advanced Airbag System
consists of the following:
-Crash sensors in the front of the veh icle that
measure ve hicle acceleration/dece le ration
to provide information to the Advanced Air­ bag System about the severity of the crash.
A irbag system 15 5
- An electron ic contro l unit, with integrated
crash sensors fo r front and side impacts .
T he control un it "decides" whether to f ire
the front a irbag s based on the informat ion
received from the crash sensors. The control
unit also "decides" whether the safety belt
pretens ione rs should be act iva ted .
- An Advanced A irbag w it h gas genera tor and
cont ro l valve for the driver ins ide the steer ­
ing wheel h ub.
- An Advanced A irbag w ith gas generator and
cont ro l valve inside the instrument panel for
the front passenger .
- A capacit ive passenger detection system un ­
derneath the front passenger seat cover .
This system measu res the ele ct rical capac i­
t ance of the perso n in the seat. The informa ­
t ion registered is se nt cont inuo usly to the
elec tronic con trol un it to regu late dep loy­
ment of the front Advanced Ai rbag on the
passenger side.
-An airbag monitoring system and ind icator
light in the instr ument cluster ¢
page 159.
-A senso r in each front seat registers the dis ­
tance between the respective seat a nd the
steering whee l or instrument panel. The in­
formation reg istered is sent cont inuo usly to
the electron ic contro l unit to regulate de­
ployment of the front Adva need A irbags .
- The
PASSENGER AIR BAG OFF li ght comes
on and stays on in the center of the instr u­
ment panel ¢
page 160, fig. 160 and tells
you whe n the front Advanced Airbag on the
passenger side has been tu rned off.
- A senso r in the safety belt latch fo r the d riv ­
er and fo r the front seat passenger that
senses whethe r th at safety belt is latched or
no t and tra nsmi ts this informa tion to the
elec tronic con trol un it.
A WARNING
D amage to the fron t passenger se at can
p revent the front air bag from work ing
p roperly.
- Imp roper repai r or disassembly of the
front passenge r and dr iver seat will pre­
vent the Advanced Airbag System from
functioning properly.

156 Airbag system
-Repairs to the front passenger seat must
be performed by qualified and properly
trained workshop personnel.
- Never remove the front passenger or
driver seat from the vehicle.
- Never remove the upholstery from the
front passenger seat.
- Never disassemble or remove parts from
the seat or disconnect wires from it.
- Never carry sharp objects in your pockets
or put them on the seat. The capacitive
passenger detection mat in the front
passenger seat will not function properly
if it is punctured .
- Never carry things on your lap or carry
objects on the front passenger seat.
Such objects can influence the capaci­
tance registered by the capacitive pas­ senger detection system, so that incor­
rect information is provided to the airbag
control unit.
- Never store items under the front pas­
senger seat. Parts of the Advanced Air­
bag System under the passenger seat
could be damaged, preventing them and
the airbag system from working proper­
ly.
- Never place seat covers or replacement upholstery that have not been specifical­
ly approved by Audi on the front seats.
- Seat covers can prevent the Advanced
Airbag System from recognizing child re­
straints or occupants on the front pas­
senger seat and prevent the side airbag
in the seat backrest from deploying prop­
erly .
- If a seat heater has been retrofitted or
otherwise added to the front passenger
seat, never install any child restraint sys­
tem on this seat.
- Never use cushions, pillows, blankets, or similar items on the front passenger
seat. The additional layers prevent the
capacitive passenger detection system
from accurately measuring the capaci­
tance of the child safety seat and/or the
person on the seat and thus keep the Ad- vanced Airbag System from working
properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat
heater for child seats) on the front pas­
senger seat if the device is connected to
the 12-volt socket or the cigarette light­
er socket . Such devices can influence the
capacitance registered by the capacitive
passenger detection system, so that in­
correct information is provided to the air­
bag control unit.
- If you must use a child restraint on the
front passenger seat and the child re­
straint manufacturer's instructions re­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certain that the
PASSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
straint is installed on the front passen­
ger seat.
- If the
PASSENGER AIR BAG OFF light
does not come on and stay on, immedi­
ately install child restraint in a rear seat­
ing position and have the airbag system
inspected by your Audi dealer.
.&_ WARNING ~
If the front passenger seat gets wet, dry it
immediately.
- If liquid soaks into the front passenger
seat, this can keep the airbag system
from working properly and may, for in­
stance, deactivate the passenger frontal
airbag. If this happens, the
PASSENGER
AIR BAG OFF
light will come on and stay
on together with the airbag indicator
light
fl in the instrument cluster .
- If liquid is pooled on the seat, but has
not soaked in, this may also keep the air­
bag system from working properly and
cause the passenger frontal airbag to be
enabled (turned on), even though there
is a properly installed child restraint sys-
tem on the seat. Wet towels or other wet

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective cata lytic reduction,
an urea solution (Ad B lue) is injected into the
exhaust system before a nitrogen oxide cata­
lytic converter to reduce nitrogen emissions.
The Ad Blue is stored in a separate tank in the
vehicle. The Ad Blue usage accounts for ap­
proximately 0.5% to 1.2% of the diesel fuel
that is used.
You must refill the Ad Blue or have it refilled
by you r authorized Audi dea ler or qualified
workshop as soon as the Ad Blue refill mes­
sage appears in the instrument cluster
¢page 222.
A WARNING
-Failure to heed AdBlue refill information in
the instrument cluster can prevent the ve­
hicle from be ing started and driven . If the
vehicle cannot be driven and an emergency
arises, personal injury can occur.
- Always have the AdBlue tank refilled well
before the tank runs dry.
(D Tips
-The instrument cluster display ind icates
the distance remaining that can be driv­
en
c> page 221. If the Ad Blue tank is
completely empty, the engine will not
start again after the ignition is switched
off.
-Ad Blue is required by law to operate this
vehicle.

Fig . 185 Ad Blue filler tube: inse rting the refill bottle
The AdBlue fi ller tube is located near the die­
sel filler tube . Always add 1.5 gallons (5. 7 lit­
ers) of AdBlue (three bottles). This is the mini­
mum amount required to ensure the system
detects the refilling and to start the eng ine.
The AdBlue tank capacity is approximately
4 .5 gal lons (17 liters).
Opening the filler tube and adding
AdBlue
Requirement : The request to add Ad Blue must
appear in the instrument cluster display.
• Switch the ignition off .
• Open the tank cover

• Press lightly against the bottom of the bot­
tle @to empty it. Continue pressing the
bottom of the bottle until it is empty or un­
til fluid stops flowing into the tank.
• Turn the bottle to the left without pressing
on the bottom .
Closing the filler tube
• Turn the cap clockwise on the filler tube
with the lug wrench until you hear it tighten
completely .
• Close the tank cover.
After filling
The vehicle must be driven. The system may
take up to two minutes to detect that the
AdBlue has been f illed.
• If there was no Ad Blue left in the tank and a
range of
O mi (0 km) was displayed in the
instrument cluster, switch the ignition on
for about 15 seconds before starting the en­ gine.
A WARNING
= Ad Blue can irritate the sk in, eyes and res-
piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a physician if necessary.
(D Note
- Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any
additives with the AdBlue and do not d i­
lute it with water.
-A d Blue is not a diesel add itive . Do not
add it to the diesel tank. If Ad Blue is
m ixed with diesel fuel, it can lead to
damage to the engine and the AdBlue
tank system . The Limited New Vehicle
Warranty does not cover such damage.
- Ad Blue attacks surfaces such as painted
vehicle components, plastic and carpet.
Remove the fluid as quickly as possible
w ith a damp cloth and p lenty of cold wa­
ter. If the AdBlue has already crystal-
lized, use warm water and a sponge. .,..

(D Note
Driving with an insufficient oil level is like­
ly to cause severe damage to the engine.
@ Tips
- The oil pre ssure w arning di spl ay . is

befor e going on a long tr ip .
- If you have the impression your engine
consumes excessive amounts of oil, we
recommend that you consult your Audi
dealer to have the cause of yo ur conce rn
properly diagnosed. Keep in mind that
the accurate measurement of oil con­
sump tion requires great care and may
take some time. Your Audi dealer has in­
str uctions about how to measure oil con­
sumption accurately.

Most ti res lose a ir naturally over time. They
can also lose some a ir if you drive over a pot­
hole or hit a curb while parking. It is usua lly
not possib le to see whether the radia l tires
used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at
l east once a month and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long ." See ¢
page 248 , Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when check ing and adjusting inflation pres­
sures . Check all of the t ires and be sure not to
forget the spare t ire . If the pressure in any tire
i s too high when the tire is "cold," le t air out
of the tire slowly with t he edge of the t ire
gauge and keep checking the pressure until
you reach the press ure that is correct for the
l oad (passengers and luggage) and kind of
driving you plan to do .
I f the p ressure in any tire is too low, note the
difference between the pressure in the cold
tire and the pressure yo u need and add the a ir
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the t ires on your vehicle as listed on the on
your veh icle and in this manua l and the kind
of dr iv ing yo u plan to do .
Never e xceed the ma ximum inflation pres ­
sur e listed on the t ire s idewall for any rea ­
son.
Remember that the vehicle manufacturer, not
the t ire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the requi red ti re press ure from the tire
pressure label. The tire pressure labe l is lo­
cated on the driver's side B-pi llar .
Tire s an d wheel s 24 7
- Turn the va lve stem cap counter -clockw ise
to remove it from the tire va lve .
- Place the air pressure gauge on the va lve.
- The tire pressures should o nly be checked
a nd ad justed when the tires are co ld. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on t he va lve.
When should I check the tire pressure?
The correct tire pressure is especially impor­
tant at high speeds . The pressure should
the refore be checked at least once a month
and always before sta rting a jo urney. Do not
f o rge t to chec k the ti re p ressu re fo r the sp are

When should I adjust the tire pressures ?
Adjust the tire pressure to the load you a re
ca rrying. After chang ing a whee l
or replacing
whee ls you have to adjust the ti re p ressu res
on all whee ls. In addition, yo u m ust then
store the new tire pressures in the tire pres ­
s u re monito ring system*
q page 258.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RI] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handli ng of the vehicle and
stopping ability.
- Incorrect tire pressures and/or underin­
f lation can a lso lead to sudden t ire fail­
ure, including a blowout a nd sudden de­
f lation, ca using loss of veh icle cont ro l.
- The drive r is responsib le for the co rrect

signal low tire 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

properly . Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
