(D Note
-Be aware that just one tank fi lling with
le ad ed fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page 199.
-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 could cause
the catalyt ic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Shutting down vehicle
If you would like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Audi or other specialized dealer. They can ad­
vise you on necessary precautions e .g. corro ­
sion prevention, maintenance and storage.

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex ­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely depend on three factors:
- your personal d riving style
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Transpo rt Canada may not cor re­
spond to your actual consump tion on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con ­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most f uel when they a re ac­
ce lerat ing. If you ant icipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.

182 Driving and en vironm ent
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage .
"'Try and keep well below your car 's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
g ine no ise increase d isproportionately at high
speeds. If you dr ive at approximately three
quarters of top speed, fuel consumption will be reduced by one half. Never dr ive faster
than the posted speed limit and weather con­
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
"'Shut the engine off when you are not dr iv ing
the vehicle .
"'Do not warm up the veh icle by letting the
engine run at idle .
It makes sense to shut
off the e ngine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings , or at traff ic lights that have
l ong wa its on red. Turning the engine
off fo r
just
30-40 seconds saves more fue l than is
bu rned s tarting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . Howeve r, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
([) Note
Do not leave engine idling unattended af ­
ter starti ng . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over- heating o
r othe r damage to the ve hicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
"' Have your ve hicle serviced at reg ular in ter -
vals.
By having your veh icle regu la rly serviced by an
a utho rized Aud i dea le r helps to ensure that it
runs properly and econom ic all y. The cond it ion
of your veh icle not on ly affe cts its safety and
ability to ho ld its va lue, it a lso affects
fuel
con sumption .
Check your oil ea ch time you fill your tank.
The amount of o il used is re lated to engine
load and speed .
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l cons umption and en­
gine output.
(D Note
- Have your vehicle maintained proper ly
and in accordance with the service rec ­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
em iss ion contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control Sys tem unless ap­
proved by the manufacture r.
- Do not alte r or remove any device, such
a s hea t sh ie lds, swi tches, ig nitio n w ires,
valves, which are designe d to p rotec t
your vehicle's Emission Control System
and other impo rtant vehicle compo­
nents .

198 Checking and filling
Using the proper engine oil is important for
the functionality and service life of the en­
gine. Your engine was factory-filled with a
high-quality oil which can usually be used
throughout the entire year.
0 Note
Your Limited New Vehicle Warranty does
not cover damage or malfunctions due to
failure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance booklet.
- Use only a high quality engine oil that ex­
pressly complies with the Audi oil quality
standard specified for your vehicle's en­
gine . Using any other oil can cause seri­
ous engine damage.
- Do not mix any lubricants or other addi­
tives into the engine oil. Doing so can
cause engine damage.
If you need to add oil and there is none
available that meets the Audi oil quality
standard your engine requires, you may
add a total of no more than 0.5 quart/liter
of a high-quality "synthetic"oil that meets
the following specifications.
- Vehicles with gasoline engine: ACEA A3
or API SM with a viscosity grade of
SAE 0W-30, SAE SW-30 or SAE SW-40.
- For more information about engine oil
that has been approved for your vehicle, please contact either your authorized
Audi dealer or Audi Customer Relations
at 1 (800) 822-2834 or visit our web site
at www.audiusa .com or
www .audicanada .ca .
Engine oil consumption
The engine in your vehicle depends on an ade ­
quate 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 in­
ternal combustion engines consume a certain amount of oil. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typically, engines
with a specified break-in period (see
¢ page 179) consume more oil during the
break -in period than they consume after oil
consumption has stabilized.
Under normal conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions . Further fac­
tors are the amount of oil dilution from water
condensation or fuel residue and the oxida­
tion level of the oil. As any engine is subject to
wear as mileage builds up, the oil consump­
tion may increase over time until replacement of worn components may become necessary.
With all these variables coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regular and frequent checking of the oil lev­ el, see
Note.
If
the yellow engine oil level warning symbol
El in the instrument cluster lights up, you
should check the oil level as soon as possible
¢ page 199. Top off the oil at your earliest
convenience
¢ page 199.
A WARNING
--
Before you check anything in the engine
compartment, always read and heed all
WARNINGS¢
& in Working in the engine
compartment on page 195.
{(D Note
Driving with an insufficient oil level is like­
ly to cause severe damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals, pref­ erably each time you refuel, and always
before going on a long trip. .,.

@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow lega l regu lations
when disposing of empty oil containers.
Changing the engine oil
We recommend that hove your oil changed by
on authori zed Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lways r ea d and h eed all W ARN ·
ING S
q & in Working in the engine comport­
ment on page 195.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradually dur ing normal veh icle use .
Under some circumstances the engine oi l
should be changed more frequently . Change
oil more often if you drive mostly short dis­
tances, operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con·
d itions, or have your veh icle where tempera·
tures remain below freez ing fo r extended pe­
riods.
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing for a short time. This is no rma l and is not
a reason to change the oil more often than recommended.
Because of the prob lem of proper disposal ,
a long w ith the special tools and necessary ex­
pertise required, we strong ly recommend that you have your oil changed by an authorized
A
udi de ale r or a qualified service station.
If yo u choo se t o c hange y our oi l yourse lf ,
please note the follow ing important informa ­
t ion:
_& WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection .
- To reduce the risk of burns from hot en -
gine oi l, let the engine cool down to the
touch .
- When removing the o il dra in p lug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the ground to help prevent hot oil from run· n ing down your arm.
- Dra in the oil into a container designed
for this purpose, one large enough to hold at least the tota l amount of oil in
your engine .
- Engine oil is poisonous. Keep it we ll out
of the reach of children.
- Continuous contact with used eng ine o il
is harmful to your sk in . Always protect
your skin by washing oil off thoroughly
wit h soap and water.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
g ine and adversely affect your Aud i Limit­
ed New Veh icle Warranty.
@ For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose of the used oil.
- Always dispose of used eng ine oil proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams or down
sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collect ion faci lity in you r
area, or contact a service station.

24 0 T ire s and wheel s
According ly, when the low tire pressure te ll­
tale illuminates, you shou ld stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a s ig­
n ificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dli ng and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
p ressu re, even if under- inflation has not
reached the leve l to trigger ill umination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not opera ting properly. The
TPMS mal function indicator is combined wi th
the low tire press ure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash fo r approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequen t vehicle
start -ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons , includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
p roperly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function p roperly. Tire pressure indicator appears
Applies to vehicles: wit h tire press ure mo nitor ing system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction .
