Single-trip memory (Trip computer 1 )
The sing le- trip memory stores the tr ip infor ­
mation from the time the ign it ion is tu rned on
u nt il it is turned off.
If t he trip is cont inued
with in 2 hour s from the time the ignition was
turned off, the new data will be included in ..,.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reac h the cata lytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, t he 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 159
fuel consumption by 10 -15 percent. This 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 publishe d
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 maximum
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 app roximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Nev er drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

160 Driving and en vi ro nment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic l ights 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 starting the eng ine again .
It takes a long time for the engine to warm up
fu lly 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 should come
on to indicate imp roper 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 serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dea ler 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 ability to
hold its value, it also affects fuel consump­
tion .
Check you r oil ea ch time you fill you r tank. T
he 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
(S,000 kilometres) before yo u can properly
assess oil consumpt ion.
T his 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, ign it 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 consumption 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
General information
Your Audi TT Roadster is not designed to tow
a trailer.
Tow ing a tra ile r with you r Audi T T Roadste r is
n ot re commended and can ca use damage to
t he car . D ama ged ca use d by towing a trailer is

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 regarding
quality and viscosity so that it can run
smooth ly and reliab ly . Choosing the right o il
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than 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 i t needs fo r proper opera­
t io n.
Modern engine lubr ication has taken a quan­
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 181
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,
ACEA AS or ACEA BS or AP! SL specifications,
but even then, only in viscosity grades SA E
SW-40, SAE SW-30, or SAE OW-40 . However,
during the entire time between oil change in­
tervals , never top
off with more than a total
of 0 .5 qt/liter engine oil that does not con­
form to Audi oil specification 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.
•
•

182 Checking and filling
Deterge nt additives in the o il wi ll make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00. Yo ur Limited New Veh icle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty& Maintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in period (see
c::;, page 157) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
m lights up, yo u
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::;, page 183. Top off the
o il at your earliest conve nience
c::;, page 183 .
A WARNING
-Before you chec k anything in the engine
compartment, a lways read and heed a ll
WAR NIN GS
c::;, .& in Working in the engine
comportment on page 178.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
re ly on it . Instead, check the oil level in
your engine at r egular interval s, pr ef­
erably e ach time you refu el, and always
before going on a long trip.
- If you have the impressio n yo ur engine
cons umes ex cessive amoun ts of oil, we
recommend that you consult your Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requ ires great care and may
take some t ime . Your Audi dea ler has in­
struct ions about how to measure oil con­
sumption acc urately.
