& WARNING (conti nued)
• Always make sure that the side a irbag can inflate without
interference :
- Never in stall seat covers or replacement uphol stery over the
front seatbacks that have not been specifically approved by
Audi .
- Never use addit ional se at cushions that cover the areas
where the side ai rbags inflate.
- Damage to the or iginal seat covers or to the seam in the area
of the side airbag module must always be repaired immedi
ately by an author ized Audi dealer.
• The airbag system can be activated only on ce. After an airbag
has inflated, it must be replaced by an authorized Audi dealer or
qualified technician who has the techni cal information, t raining
and special equipment necessary.
• The airbag sy stem can be deploy ed only once. After an airbag
has been dep loyed , it must be replaced with new replacement
parts designed and approved e specially for your Audi model
version. Replacement of complete airbag systems or a irbag
components must be performed by qualified workshops onl y.
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .a
Other things that can affect Advanced
Airbag performance
Changing the ve hicle's suspension system can change the way that
t he A dvan ced Airbag Sys tem pe rfo rms in a crash . For examp le, using
tire -rim combinations not approved by Audi, lower ing t he veh icle,
c hang ing the st iffness o f th e suspens ion, including the sp rings,
suspension str uts , shoc k absorbers etc . ca n change the forces tha t
are meas ured by the a irbag sensors and sent to the electronic control
unit. Some suspension changes ca n, for examp le, increase the force levels measured by the senso
rs and make the airbag system deploy in
c ra shes in w hich i t wo uld not deploy if the ch an g es h ad not b een
made . Other ki nds of changes may reduce the force levels meas ured
by the sensors an d prevent the airbag from dep loying when it should .
Th e sensors in t he safety bel t buckle for the drive r and fro nt
passenger seat tell the e lectronic control mo dule if the sa fety belt is
la tch ed o r not. If the safety belt is being u sed, t he fron t airbag w ill
dep loy at a sl ightly h igher rate of vehicle deceleration than if the
s afety belt is not be ing use d. T herefo re, in a pa rticular collis io n, it is
possible that an a irbag w ill not deploy at a seati ng position where the
sa fety belt is being used but w ill inflate at the posit ion where the
safety belt is not be ing used . It is importa nt that nothi ng inte rfere
w ith the safety belt buck les so that t he sensors can send the co rrect
info rmation abou t safety b elt use to t he electron ic co ntro l unit .
& WARNING
Changing the vehicle 's suspension including use of unapproved
tire-rim combinations can change Advanced Airbag performance and increase the risk of serious personal injury in a crash .
• Never install suspension components that do not have the
same performance characteristics as the components originally
installed on your vehicle.
• Never use tire-rim combinations that have not been approved
by Audi.
& WARNING
Item s stored between the safety belt buckle and the center
console can cause the sensors in the buckle to send the wrong
information to the electroni c control module and prevent the
Advanced Airbag System from work ing properly.
• Always make sure that nothing can interfere with the safety
belt buckles and that they are not obstructed . ..,

Driving and environment
------------------------------------------------'
you start the engine and avoid running at high RPMs while the engine
is still warming up.
0 Note
Do not leave engine idling unattended after starting. If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which could result in
overheat ing or other damage to the vehicle or other property.•
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehicle serviced at regular intervals.
By having your vehicle regularly serviced by an authorized Audi dealer
helps to ensure that it runs properly and economically. The condition
of your vehicle not on ly affects its safety and ability to hold its value,
it also affects
fuel consumption .
Check your oil each time you fill your tank.
The amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mi leage has been driven.
You must drive you r vehicle about 3,000 miles (5,000 kilometers)
before you can properly assess oil consumption.
Thi s also applies to fuel consumption and engine output.
0 Note
• Have your vehicle maintained properly and in accordance with the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle will
impa ir the function of the emission control system and could lead to
damage.
Controls and equip ment Safety first Vehicle operation
•
Do not alter or remove any component of the Emission Control
System unless approved by the manufacturer.
• Do not a lter or remove any device, such as heat shie lds, switches,
ignition w ires, va lves, which are designed to protect your vehicle 's
Emission Control System and other important vehicle components.
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short distances with a cold engine.
The engine and catalytic converter have to reach their optimal oper
ating temperature
to reduce fuel consumption and noxious emis
sions effectively .
• Just after starting, a cold eng ine in a mid-size car burns the fuel at
a poor rate of 6-8 miles per gallon (30-40 l/l00km). Half a mile down
the road, the mileage improves to 12 MPG (20 l/100 km). It will take
the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operat ing temperature and operate at an
economic mileage . This explains why taking the car for sho rt trips is a
rather wasteful convenience .
• Th e
outside temperature is also critical in this regard . Your car
consumes more fuel in the winter than in the summer.

prevent the formation of harmful deposits, sometimes called
"sludge," that
over time can lead to expensive repairs.
At the time of printing, engine o ils available in the U .S. and Canada
that meet the exacting specifications of Audi oil standard VW 502 00
(vehicles with gasoline eng ine) and VW 507 00 (vehicles w ith diesel
engine) are synthetic engine oils. This does not mean, however, that
every synthetic engine oil will meet Audi oil standard VW 502 00
(gasoline engines) and VW 507 00 (diesel engines). So always be sure
that you use an approved oil.
To help prevent the formation of harmful deposits use only oil with
the following specifications printed on the oil container:
• Gasoline engines: Audi oil standard VW 502 00
• Diesel engines: Audi oil standard VW 507 00
Oil containe r labels may carry the specification singly or in comb ina
tion with other des ignations and oi l quality standards.
Viscosity
Engine oils are graded according to their viscosity. The proper
viscosity grade oil for your engine depends on climactic or seasonal
conditions where you drive. You can use oil with a v iscosity grade of
SAE SW-40 across all temperature ranges for norma l dr iv in g cond i
tions.
However, if eng ine o il viscosity grade SAE SW-40 is not available, you
can also use viscosity grade SAE SW-30 or SAE OW-40 as long as it
meets Audi o il quality standard VW 502 00 (vehicles w ith gasoline
engine) or VW 507 00 (vehicles with diesel engine) specifications.
Because engine o il that meets the Audi oil standard may not be avail
able everywhere when you need it, we strongly recommend that you
always ca rry with you an extra quart (liter) of oil that express ly
conforms to the VW 502 00 (vehicles with gasoline eng ine) or VW
507 00 (vehicles with diesel engine) specification, in case you have to
top off the oil while on the road .
Applies to vehicles with gasoline engine only: Only if the leve l of the
oil is at or below the minimum mark on the oil dipstick - and no oil
Safety first
that expressly conforms to Aud i oil standard VW 502 00 specifica
tions is available -may you top off with a high quali ty engine oil, pref
erably synthetic-based, that meets ACEA A3, ACEA AS, ACEA BS or
API SL specifications, but even then, only in viscosity grades SAE SW-
40, SAE SW-30, or SAE OW-40. However, during the ent ire time
between oil change interva ls, never top off with more than a total of
0.5 qt/liter engine oil that does not conform to Audi oil specification
vw 502 00.
Applies to vehicles with diesel engine only : Only if the level of the
oil is at or below the minimum mark on the oil dipstick -and no oil
that expressly conforms to Audi oil standard VW 507 00 specifica
tions is ava ilable -may you top off with a high qua lity engine oil, that
meets ACEA C3 or API CF specifications, but even then, on ly in
viscos ity grades SAE SW-40, SAE SW-30, or SAE OW-40 . However,
during the entire time between oil change intervals, never top off
with more than a tota l of 0.5 qt/liter engine oil that does not
conform to Audi o il specification VW 507 00.
For more information about engine oil that has been approved fo r
your vehicle, please contact either your author ized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834 or visit our web site at
www.audiusa.com or www .aud icanada.ca. Here you w ill also find a
current list of oils (manufact urers, brand names etc.) that conform to
Audi oil standard VW 502 00 (vehicles with gasoline eng ine) or VW
507 00 (vehicles with diesel engine).
Changing the engine oil
The engine oil and oil filter must be changed accord ing to the mileage
(kilometers) and time interva ls specified in your vehicle's Warranty
&
Maintenance booklet. Do not exceed these intervals -harmful
deposits from o ld engine oil can reduce engine performance and can
lead to expens ive engine repairs.
Chang ing the oil at the recommended intervals is so very important
because the lubricating p roperties of oil decrease g radua lly during
normal veh icle use. If you are not sure when you have your o il
changed, ask your authorized A udi Service Adv isor. ..,.
Vehicle care Technical data
Page 232 of 320

___ C_ h_ e_c _k _i _ n _g ~ a_n _d_ f_il _l_in _ g _________________________________________ _
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or mostly under stop
and-go traff ic conditions, or when you use your vehicle where temper
atures stay below freezing point for long periods .
Detergent additives in the oil will make fresh oil look dark after the
engine has been run ning for a short time . This is normal and is not a
reason to change the oil more often than recommended .
Damage or malfunctions due to lack of maintenance
It is essentia l that you change your oi l at the recommended intervals
using only engine oil that complies with Audi oi l standard VW 502 00
(vehicles with gasoline engine) or VW 507 00 (vehicles with diesel
engine). Your Limited New Vehicle Warranty does not cover damage
or malfunctions due to failure to follow recommended maintenance
and use requirements as set forth in the Audi Owner's Manua l and
Warranty
& Maintenance booklet. Your dealer will have to deny
warranty coverage unless you present to the dealer proof in the form
of Service or Repair Orders that all scheduled maintenance was
performed in a timely manner .•
Engine oil consumption
The engine in your vehicle depends on an adequate
amount of oil to lubricate and cool all of its moving parts.
In order to provide effective lubrication and cooling of internal
engine components, all internal combustion engines consume a
certain amount of o il. Oil consumpt ion varies from engine to engine
and may change significant ly over the life of the eng ine. Typically,
engines with a specified break- in period (see~
page 197) consume
more oi l during the break-in period than they cons ume after oil
consumption has stabilized.
Under normal cond itions, the rate of oil consumpt ion depends on the
quality and vis cosity of the oil, the RPM (revol utions pe r minute) at
which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oi l dilution from water condensation or fuel residue and the ox
idation level of the o il. As any
eng ine is subject to wear as mileage builds up, the oil consumption
may increase over time until replacement of worn components may
become necessary.
With all these variab les coming into play, no standard rate of oil
consumption can be established or specified. There is no alternative
to regular and frequent checking of the oil level , see
Note .
If the yellow engine oil level warning symbol in the instrument
cl uster .... lights up, you should check the oil level as soon as possible
with the oil dipstick~ page 231. Top off the o il at your earliest
convenience ~
page 232.
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS~
& in "Work ing in the engine
compartment" on
page 226.
0 Note
Driving with an insufficient oil level is likely to cause severe 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, preferably each time you refuel, and alway s
before going on a long trip.
• If you have the impression your eng ine consumes excessive
amounts of oi l, we recommend that you consu lt your authorized Audi
dea ler to have the cause of your concern properly diagnosed. Keep in
mind that the accurate measurement of oil consumption requires
great care and may take some time . Your authorized Audi dea le r has
instructions about how to measure oil consumption accurately. •

tion (with frost protection in the winter).

Tire service Life
The servi ce life of tires depends on a lot of different
things including proper installation and balancing,
correct tir e pressure and driving style.

The original t ires o n your veh icle have 1/16 inch ( 1.6 mm) h igh "wear
ind icators"~ fig. 173 running across the tread . Depending on the
ma ke, there w ill be six to eight of them even Ly placed around the ti re.
Marks on the t ire sidewall (for examp le "TWI " or other symbols) indi
cate the positions of the tread wea r indicators . Worn t ires must be
replaced. Differe nt figu res may apply in other countries ~ & .
Tire pressure
Incorrect tire pressure causes premature wea r and can cause sudden
tire blow-o ut. Fo r th is reason, tire pressu re must be checked at least
once a month~
page 252.
Driv ing style
Driving fast aro und curves, heavy accele ration and hard b raking
increase tire wear .
Rotating tires for more even wear
For all four tires o n your ve hicle to have the same se rvice life, we
recommend that the fron t and rear t ires are rot ated according to the
tire manufact urer's suggested tire rotat ion intervals . Please
remember the fo llow ing :
• Tir e ro tat ion inte rvals may d iffe r from the vehicle serv ice intervals
out lined in your Warranty
& Maintenance Booklet.
• The longer one tire is used in one locat ion on the vehicle, the more
it wears at certain points; therefore, we recommend that you follow
the t ire manufacture r's sugges ted tire rotation interva ls .
• Vehicles with front-whee l drive experience more tread wea r on the
front wheels compa red to a ll-wheel dr ive (quattro ®).
• Please ro ta te tires as shown~
page 256, fig. 174.
• Extra care must be taken when rotating direction -specific t ires

Wheel balancing
The wheels on new vehicles are balanced. However, var ious si tuatio ns
dur ing everyday driving can cause them to become unbalanced,
resu lting in v ibr ations yo u can us ua lly fee l throug h the stee rin g
w heel.
Unbalanced whee ls mus t be rebalanced to avoid excessive wea r on
steeri ng, suspension and tires . A wheel must also be rebalanced
when a new tire is installed.
