- Lack of proper maintenance as well as improper use of the
vehicle will impair the function of the emission con trol system
and could lead to damage.
Even when the Emission Control System is operating properly, the
exhaust gas can have a su lfur -like exhaust gas smell under some
operating states . This depends on the su lfur content of the fuel
being used. Using a different brand of fuel may he lp, or filling the
tank with lead-free super grade gasoline. •
Avoid damaging the vehicle
When you are driving on poor roads, or over curbs, steep ramps,
etc., make certain that low-lying parts such as spoilers and exhaust
system parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung chassis (sports
chassis) and fully loaded vehicles. •
Operate your vehicle economically
and minimize pollution
General
Your personal style of driving will determine the economy
of your vehicle, as well as exhaust and noise levels.
Fuel economy, environmental impact, and wear on your engine,
brakes and t ires largely depend on three factors:
• your personal driving style
• operating condit ions
• technical limitations If
you anticipate what you need to do next and drive economically,
you can easily cut your fuel consumption by 10-15 percent . This
section will give you some tips on how you can he lp the environ­
ment and your pocketbook .
[ i ] Tips
The consumption estimates as published by ENVIRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actua l consumption on the road, which will vary
depend ing upon vehicle load and speed, road and weather condi­
tions, trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating.
Avoid unnecessary accelerating and braking.
Vehicles use the most fue l when they are accelerating . If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic 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 lerating gently reduces fuel consumption, engine wear, and
does not disturb the environment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds. If you drive at approximately
three quarters of top speed, fuel consumption wil l be reduced by
9J,,

one half. Never drive faster than the posted speed limit and weather
conditi ons permit. •
Reducing unnecessary Idling
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the eng ine run at
idle.
I t makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at railroad crossings, or at traffic lights that have long waits on red. Turning the engine off for just 30 -40 seconds
saves more fue l than is burned s tarting the engine again .
It takes a long time for the engine to warm up fully when it is
running at idle . However, wear and noxious emissions a re especial ly
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 stil l 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 idl ing also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .•
Regular maintenance
A badly tuned en gine unnecessarily wastes a lot of fuel.
- Have your v ehicl e serv ice d at reg ular intervals.
Controls and equip­
ment Safety first Vehicle operation
Dri
ving and environm ent
By having your vehicle regularly serviced by an Audi dea ler helps to
ensure that i t runs properly and economically . The conditio n of your
vehic le not only affects its safety and abi lity to hold its va lue, 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 .
I t is normal for the oi l consumption of a new eng ine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometres) be fore you can proper ly assess o il consumpt ion.
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
t he service recommendations in you r Warranty

booklet. Lack of proper ma intenance as well as improper use of the
vehicle wi ll impair the function of the emission control system and
cou ld lead to da mage.
• Do not alter or remove any component of the Emission Contro l
System unless approved by the manufacturer .
• Do no t al te r or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
veh ic le' s Emission Contr ol System and o ther i mportant vehicle
components. •

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 engine in a mid -size car burns the fuel
at a poor rate of 6-8 miles per gallon (30-40 l/100kml. Half a mile
down the road, the mileage improves to 12 MPG (20 1/100 kml. It will
take the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operating temperature and operate at an
economic mileage. This explains why taking the car for short trips is
a rather wasteful convenience.
• The
outside temperature is also critical in this regard. Your car
consumes more fuel in the winter than in the summer.
Trailer towing
General information
Your Audi TT Coupe is not designed to tow a trailer.
Towing a trailer with your Audi TT Coupe is not recommended and
can cause damage to the car. Damaged caused by towing a trailer is
not covered by your Audi Warranty. •

Engine oil consumption
The engine in your vehicle depends on an adequate
am ount of oil to lubricate and c ool 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 oil. Oil consumption varies from engine to engine
and may change sign ificantly over the life of the engine . Typically,
engines with a specified break-in period (see~
page 190) consume
more oil during the break-in period than they co nsume after o il
consumption has stabilized .
Under normal conditions, the rate of oil consumption depends on
the quality and viscosity of the oil, the RPM (revo lutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil dilution from water
condensation or fue l residue and the oxidation level of the oil. As
any engine is subject to wear as mileage bu ilds up, the oil consump ­
tion may increase over time until rep lacement of worn components
may become necessary .
With all these variables coming into play, no standa rd rate of oil
consumption can be estab lished or specified. There is no a lternative
t o regula r and frequent checking of the oil level, see Note.
I f the yellow engine oil level warning symbol in the instrument
cluster _ lights up, y ou should check t he oi l level as soon as
possible
with the oil dipstick~ page 221. Top off the oil at your
earl iest co nvenience ~
page 222.
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNING S
~ & in "Working in the engine
c ompartment " on
page 217 .
0 Note
Driving with an insuff ic ie n t o il level is l ikely to cause severe damage
to the engine.
[ i ] Tip s
• The oil pressure w arning display ce,. is not an indi cator of the oil
level . Do not rely on it. Instead, check the oil level in your engine at
regular interv als , prefe rably ea ch time you refuel , and always before
going on a long trip.
• I f you have the impression your engine consumes excessive
amoun ts of oi l, we recommend tha t you consult your Audi dealer to
have the cause of your concern properly diagnosed . Keep in mind
that the accurate measureme nt of oil consumption requires great
care and may take some time. Your Audi dealer has instructions
about how t o measure oil consumption accurately. •

& WARNING (continued)
• The engine compartment of any motor vehicle is a potentially
hazardous area. Never reach into the area around or touch the
radiator fan. It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed. The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run
until the coolant temperature drops .
• Always remove the ignition key before anyone gets under the
vehicle.
• Always support your vehicle with safety stands if it is neces­
sary to work underneath the vehicle. The jack supplied with the
vehicle is not adequate for this purpose and could collapse
causing serious personal injury.
• If you must work underneath the vehicle with the wheels on
the ground, always make sure the vehicle is on level ground, that
the wheels are always securely blocked and that the engine
cannot be started .
• Always make sure the transmission selector lever (automatic
transmission) is in "P" (Park position) (automatic transmission) or
Neutral (manual transmission) and the hand brake is firmly
applied.
<£> For the sake of the environment
• Changing the engine settings will adversely affect emission
levels. This is detrimental to the environment and increases fuel
consumption .
• Always observe environmental regulations when disposing of
old engine oil, used brake fluid, dirty engine coolant, spent batteries
or worn out tires.
• Undeployed airbag modules and pretensioners might be classi ­
fied as Perchlorate Material -special handling may apply, see
