Operate Your Vehicle Economicallyand Minimize Pollution - Audi TT 2012 Owner's Manual

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 continue to operate your vehicle
under these conditions, as otherwise fuel
can reach the catalytic converter. This
could result in overheating of the con-
verter, requiring its replacement.
- To assure efficient operation of the Emis-
sion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec-
ommendations in your Warranty &
Maintenance booklet.
- Lack of proper maintenance as well as
improper use ofthe vehicle will impair
the function ofthe emission control
system and could lead to damage.

For the sake of the environ ment
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 sulfur content of the fuel being used.
Using a different brand offuel may help,
or filling the tank with lead-free super
grade gasoline.

General
Your personal style of driving will determine
the economy ofyour vehicle, as weil as ex-
haust and noise levels.
Fuel economy, environ mental impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technicallimitations
Ifyou anticipate what you need to do next and
drive economically, you can easily cut your
fuel consumption by 10-15 percent. This sec-
tion will give you some tips on how you can
help the environment and your pocketbook.
i
Tips
The consumption estimates as published
by ENVIRONMENTAL PROTECTION 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-
ditions, 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 fuel when they are ac-
celerating. If you anticipate 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 maxi-
mum speed.
Accelerating gently reduces fuel consump-
tion, engin.e.wl!ar, and does not disturb the
environment·.
Fuel consumption, exhaust emissions and en-
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con-
ditions permit.
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 traffic
jams, when waiting for trains to pass at rail-
road crossings, or at traffic lights that have
long waits on red. Turning the engine off for
just 30-40 seconds saves more fuel than is
burned starting 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 are especially high
when the engine is warming up. 50 you should
drive away as soon as you start the engine and
avoid running at high RPMs while the engine
is still warming up.
CD
Note
Do not leave engine idling unattended af-
ter starting. Ifwarning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could 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 byan
Audi dealer helps to ensure that it runs prop-
erly and economically. The condition ofyour
vehicle not only affects its safety and ability to
hold its value, it also affects fuel consump-
tion.
Check your oil each time you fill your tank.
Driving and environ ment
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
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometres) before you can properly
assess oil consumption.
This also applies to fuel consumption and en-
gine output.
CD
Note
- Have your vehicle maintained properly
and in accordance with the service rec-
ommendations in your Warranty & Main-
tenance booklet. Lack of proper mainte-
nance as well as improper use of the ve-
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any compone nt of
the Emission Control System unless ap-
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo-
nents.
Fewer short trips
Fuel cansumption will olways be relatively
high on shart trips.
~ Try to avoid driving short distances with a
cold engine.
The engine and catalytic converter have to
reach their optimal operating 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/100km). Half a
mile down the road, the mileage improves
to 12 MPG (20 l/100 km). It will take the
