- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control

@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
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, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 161
fuel consumption by 10 -15 percent. Th is sec
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre
spond to your actual consumption 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 accelerat ing and braking .
Vehicles use the most fuel when they are ac
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maxi -
mum speed.
Acce lerat ing gently reduces fue l consump
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w il l
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con
ditions perm it.

162 Driving and en vironm ent
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
engine run at idle .
It makes sense to shut off the engine 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
burned starti ng the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle . However , 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 whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af
ter starting . If warning lights shou ld come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over
heating 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 inter-
vals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs prop
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ab ility to
hold its value, it also affects
fuel con sump
tion .
Check you r oil ea ch time you fill you r tan k.
The amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometres) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec
ommendations in your Wa rranty
& Main
t enance boo klet . Lack of p roper ma inte
nance as well as improper use of the ve
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap
proved
by the manufacturer.
- Do not alter or remove any device, such
as heat sh ie lds, switches, ignit ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal
operat ing temperature to
reduce fuel consumpt ion and nox ious emis
s ions effectively .
- Ju st after starting, a cold engine in a mid
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road, the mileage improves
to 12 MPG (20 l/100 km). It w ill take the
ll>
engine no less than two and a half miles
(4 km) of driving to warm up to its proper
operating tempe ratu re and ope rate at an
economic mileage. This explains w hy taking
t h e car for s hort tr ips is a rather wastefu l
convenience .
- The
outs ide temperature is also cr itical in
t hi s regard. Your car consumes more fuel in
the winter than in the summer .
Trailer towing

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
T he eng ine in your Aud i is a soph ist icated
powerplant that was built to exact ing spec ifi
cat ions . T his engine needs the right kind of
engine oil that meets specifications regard ing
quality and viscosity so that it can run
smooth ly and reliably . Choosing the right o il
and changing oil within the time and mileage
i ntervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to
day tha n it did years ago. Audi has developed
a spec ia l quality standard for engine oil that
will help assure that you r vehicle's engine w ill
get the lubr ication it needs fo r proper opera
t ion.
Modern engine l ubr ication has taken a q uan
tum leap in the last few years. Many synthet ic
1J.
oils available today provide better engine lu
brication that can outlast traditional petrole
um-based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthetic or petroleumbased engine oil, the oil that you use must
conform to Audi's oil quality standard
VW 502 00 to help keep your vehicle's engine running smoothly and help prevent the for
mation of harmful deposits, sometimes called
" sludge," that over t ime can lead to expensive
repairs .
At the time of printing, engine oils available in the U .S . and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthetic engine oils . This does not mean,
however, that every synthetic engine oil will
meet Audi oil standard VW 502 00 . So always
be sure that you use an approved oil.
To help prevent the formation of harmful de posits use only oil with the following specifi
cations printed on the oil container :
Audi oil standard VW S02 00
Oil container labels may carry the specifica
tion singly or in combination with other desig
nations and oil quality standards .
Viscosity
Engine oils are graded according to their vis
cosity . The proper viscosity grade oil for your
engine depends on climactic or seasonal con
ditions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem
perature ranges for normal driving conditions.
However, if engine oil viscosity grade SAE
SW40 is not available, you can also use viscos
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi oil quali ty standard VW 502 00
specifications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an extra quart (liter) of oil that expressly conforms to the
Checking and filling 183
VW 502 00 specification, in case you have to
top
off the oil while on the road.
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 502 00 specifications is available - may
you top
off with a high quality engine oil, pref
erably synthetic-based, that meets ACEA A3
or API SM specifications, but even then, only
in viscosity grades SA E SW-40, SA E 5W -30, or
SAE OW-40. However, during the entire time
between oil change intervals, never top
off
with more than a total of 0.5 qt/liter engine
oil that does not conform to Audi oil specifica
tion VW 502 00.
For more information about engine oil that
has been approved for your vehicle, please
contact either your autho rized Audi dealer or
Audi Customer Relations at 1 (800) 822-2834
or visit our web site at www.audiusa .com or
www.audicanada.ca . Here you will also find a
current list of oils (manufacturers, brand
names etc.) that conform to Audi oil standard
vw 502 00.
Changing the engine oil
The engine oil and oil filter must be changed
according to the mileage (kilometers) and
time intervals specified in your vehicle's War
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive engine repairs.
Changing the oil at the recommended inter
vals is so very important because the lubricat
ing properties of oil decrease gradually during
normal vehicle use. If you are not sure when
you have your oil changed, ask your author
ized Audi Serv ice Adv isor.
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 traffic con
ditions, or when you use your vehicle where
temperatures stay below freezing point for
long periods.
