Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
.,. Have your vehicle serv iced at regu lar inte r-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer he lps to ensu re that it
runs proper ly and economically. The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumpt ion.
Check your oil each tim e you fill your tank.
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
m ileage has been dr iven .
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess o il consumption .
This also applies to fuel consumption and en-
g ine output .
(D Note
- Have your vehicle maintained properly
and in accordance with the service rec-
ommendat ions in your Warranty
& Main-
tenance booklet. Lack of proper mainte-
nance as well as improper use of the ve-
hicle will impair the funct ion of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Em ission Contro l System unless ap-
proved by the manufact urer.
- Do not a lter or remove a ny dev ice, su ch

valves, wh ich are designed to protect

· Fewer short trips
Fuel consumption will always be relatively
high on short trips.
.,. Try to avoid dr iving sho rt distances w it h a
cold engine.
The engine and catalytic converter have to
reach the ir opt imal
operating te mperatur e to
reduce fuel consumpt ion and noxious em is-
sions effectively.
Just after starting, a cold engine in a mid-s ize
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/100 km). After about a
hal f a mile, fuel economy climbs to 12 mpg
(20 l/100 km). After about
2.5 miles (4 km),
the engine is at its proper operating tempera-
ture and fuel economy has reached a normal
level. So you can see that you should avo id
short trips whenever possible .
The
outside tempe rature is also critical in this
regard. Your car consumes more fuel in the
winter than in the summer.
