& WARNING
A child in a rearward-facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates -even with an Advanced Airbag System .
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, door or roof. • If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on, immediately install the rear -facing child safety seat in a rear
seating position and have the airbag system inspected by your
Audi dealer .
• Forward-facing child safety seats installed on the front
passenger's seat may interfere with the deployment of the airbag
and cause serious personal injury to the child.
& WARNING
If , in exceptional circumstances, you must install a forward-facing
child restraint on the front passenger's seat:
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag .
• Never put the forward -facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible before installing the forward -facing child
restraint. The backrest must be adjusted to an upright position .
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on .
Controls and equip­ ment Safety first
Vehicle operation
& WARNING
To reduce the risk of serious injury , make sure that the PASSENGER
AIR BAG OFF light will be displayed whenever a child restraint is installed on the front passenger seat and the ignition is switched
on .
• If the PASSENGER AIR BAG OFF light does not stay on , perform
the checks described=>
page 157, "Monitoring the Advanced
Airbag System ".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on.
• Have the airbag system inspected by your Audi dealer immedi­
ately. • Always carefully follow instructions from child restraint manu­
facturers when installing child restraints .
& WARNING
If, in exceptional circumstances, you must install a forward or
rearward-facing child restraint on the front passenger's seat :
• Improper installation of child restraints can reduce their effec­
tiveness or even prevent them from providing any protection.
• An improperly installed child restraint can interfere with the
airbag as it deploys and seriously injure or even kill the child -
even with an Advanced Airbag System .
• Always carefully follow the manufacturer's instructions
provided with the child safety seat or carrier .
• Never place additional items on the seat that can increase the
total weight registered by the weight -sensing mat and can cause
injury in a crash . •

Important safety instructions on monitoring
the Advanced Airbag System
& WARNING
An airbag system that is not functioning prope rly cannot prov ide
supplemental protection in a frontal crash.
• If the airbag ind icator light comes on , it means that there may
be something wrong with the Advanced Airbag System . It is
possible that the airbag will inflate when it is not supposed to , or
will not inflate when it should.
• Have the airbag system inspected immediately by your Audi
dealer.
& WARNING
If the front airbag inflates , a child without a child restraint, in a
rearward-facing child safety se at or in a forward-facing child
restraint that has not been properly installed will be seriously
injured and can be killed.
• Even though your vehicle is equipped with an Advanced Airbag
System , make certain that all ch ildren , especially 12 years and
younger, always ride on the back seat properly restrained for their age and size .
Controls and equip­ ment Safety first
Vehicle operation
& WARNING (continued )
• If you must in stall a rearward-facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not appear and stay on ,
immediately install the rear -facing child safety seat in a rear
seating posit ion and have the airbag system inspected by your
Audi dealer .
• A tight tether or other strap on a rearward-fa cing child restraint
attached to the front passenger seat can put too much pressure
on the weight-sensing mat in the seat and reg ister more weight
than is actually on the seat. The heavier weight registered can make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
serious or even fatal injury to the child .
• If, in exceptional circumstances, you must in stall a forward ­
fac ing child restra int on the front passenger seat , always move the
seat into its rearmost position in the seat's fore and aft adjust ­
ment range , as far away from the airbag as possible. The backrest
must be adjusted to an upright position . Make sure that the
PASSENGER AIR BAG OFF light comes on and stays on all the time
whenever the ignition is switched on .
& WARNING
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after taking the steps
described above, have the airbag system inspected by your Audi
dealer before transporting anyone on the front passenger seat .

Activating
The ESP is automatically activated when the engine is started and it
performs a self-test. You can activate a deactivated ASR if required
by pressing the=>
page 184, fig. 142 button. When it is activated,
the message
ESP/ASR on appears briefly in the display. Vehicles
with front -wheel drive a deactivated ASR automatically re -activates
itself at a speed of 40 mph (70 km/h).
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 184, fig. 142. With the ASR deactivated,
the ESP check light comes on, see=>
page 18. The message ASR off
appears in the display as well. On vehicles with front -wheel drive:
deactivation is possible only up to 30 mph (50 km/h) for safety
reasons. Vehicles with all -wheel drive : the ASR can be deactivated
at any speed.
The ASR should normally be activated all the time. Only in certain exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck.
When the abnormal situation is over, you should activate the ASR
again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i J Tips
To ensure that the ASR works properly, all four wheels must be fitted
with identical tires. Any differences in rolling radius of the tires can
Intelligent technology
cause the system to reduce engine power when this is not desired.

The rear spoiler deploys and retracts. Spoiler operation can be set
for automatic or manual operation .
Automatic mode (normal operation)
• Automatic deployment : At a speed of about 75 mph (120 km/h),
the rear spoiler deploys automatically.
• Automatic retraction: When speed drops below about 50 mph
(80 km/h), the rear spoiler retracts automatically.
Manual mode
• Manual deployment: Tapping briefly on the switch ::::> fig. 143
deploys the rear spoiler .
• Manual retraction: At speeds up to about 10 mph (20 km/h),
retract the rear spoiler by pressing and holding the switch
::::> fig. 143. At speeds between 10 mph (20 km/h) and 75 mph (120
km/h), retract the rear spoiler by tapping on the switch=> fig. 143 .

Engine oil consumption
The engine in your vehicle de pen ds on an ade quate
amount of oil to lubric ate and co ol all of its moving parts.
In order to provide effective lubrication and cooling of interna l
engine components, al l internal co mbustion engines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change sign ificant ly over the life of the engine . Typ ical ly,
engines with a specified break -in period (see=>
page 192) consume
more oil duri ng the brea k-in period than they consume afte r oil
consumption has stabi liz ed.
Unde r no rmal conditions, the rate of oil consumption depends on
the quality and viscosity of t he oil, the RPM ( revo lutions per m inute)
at which the engine is operated, the ambient temperature and road
co nd itions. Further factors are the amount of oi l dilut io n from water
condensation or fue l residue and the oxidation leve l of the oil. As
any e ng ine is subject to wear as mil eage builds up, the o il consump ­
tion may increase over time until replacement of worn components
may become necessary .
With all these var iables com ing into p lay, no standard rate of oil
consu mption can be es tab lished or speci fied. There is no a lternative
t o regular and frequent checking of the oi l leve l, see Note.
If the yellow engine oi l level warning symbol in the instrumen t
cluster _ lights up, y ou should check the oil level as soon as
possible
with the oil dipstick=> page 224. Top off the oil at your
ea rlies t conve nience =>
page 225.
ln. WARNING
Before you check anything in the engine compartment , alway s
re ad and heed all WARNINGS =>
& in "Working in the engine
c ompartment" on
page 220.
0 Note
D riving with an insufficient o il level is lik ely to cause seve re damage
to the engine .
[ i ] Tips
• The oil pressure warning display 't!:r. is not an indicator of the oil
level. Do not rely on it. Instead , check the oil level in your engine at
regular intervals , preferab ly ea ch time you refuel , and alw ays before
going on a long trip.
• I f you have the impression your engine consumes excessive
a m oun ts o f oi l, we recommend tha t you consu lt your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the acc urate measure ment o f oil co nsum ptio n requires grea t
care and may take some time . Your Audi dea ler has instructions
about how to measu re oil consump tion accurately. •

0 Note
• For technical reasons, it is not genera lly possible to use the
whee l rims from other vehic les. This can hold true for wheels of the
same vehic le type.
• If the spare tire is different from the tires that you have mounted
on your vehicle (for example winter tires or wide p rofile t ires), then
use the spare tire for a short period of time only and drive with extra
care. Rep lace the flat tire with the tire matching the others on your
vehicle as soon as possible.
• If you should put different wheels and tires on your vehic le (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compat ib le w ith the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed . For more informatio n, contact your Aud i
dea ler.
0 Note
• When insta lling new tires, be carefu l not to damage the va lves or
t ire p ressure moni toring syste m sensors .
• Never drive without the va lve stem cap. The va lves could get
damaged.
• I f the sensors must be replaced, then the valve must also be
replaced at t he same t ime.
Dispose of o ld tires in accordance with the local requ irements .•
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C Qua
lity grades can be found where applicable on the tire side wall
b etween tread shoulder a nd maximum section width =>
page 249,
fig. 164.
For example : Tread wear 200, Traction AA , Temperature A.
All passenger car tires must conform to Federa l Safety Require ­
ments in addit ion to these grades.
T read wear
The tread wear grade is a comparative rating based on the wear rate
o f t he tire when tes ted under contro lled condit ions on a specified
government test course.
F o r example, a tire g raded 150 would wear one and one half (1 1 /2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual condi ­
tions o f the ir use, however, and may depart sign ificantly from the
norm due to variations in driving habits, service practices and differ ­
ences in road characterist ics and c limate .
Traction
The traction grades, from highest to lowest, are AA, A, Band C.
Those grades represent the tire 's ability to stop on wet pavement as
measured under contro lled cond itions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor t raction performance =>& .
Temperature
The temperature grades are A (the highest), B, and C, represent ing
the tire 's resistance to the generation of heat and its ability to dissi ­
pat e heat when tested u nder con tro lled co nditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of t he ti re to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=:>& .
The grade C corresp onds to a level of performance which all
passenger car tires must meet under the Federa l Motor Vehicle
