Note
Do not leave engine idling unattended af-
ter starting . If warning 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 by an
author ized Audi dealer helps to ensure that it
runs properly 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 time 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 val ue after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometers) bef ore you can properly
assess oil consumption.
This also applies to fuel consumption and en-
gine output.

Note
- Have your vehicle maintai ned properly
and in accordance with the service rec-
ommendations in your War rant y
&
Main-
tenance booklet. Lack of proper mainte -
nance as well as imp roper 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 component of
the Emission Control System unless ap-
proved by the manufacturer .
- Do not alter or
remove
any device, such
as heat shields, switches, ignition 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.
The engine and catalytic converter have to
reach their opt imal operat ing temperature to
reduce fuel consumpt ion and noxious em is-
sions effectively.
Just after starting, a cold engine in a mid-size
car only achieves a fuel economy of 6-8 m iles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2.5
miles (4 km),
the engine is at its prope r operating tempera-
tu re and fuel economy has reached a normal
level. So you can see that you should avoid
short trips whenever possible.
The outside temperatur e is also crit ical in t his
regard. Your car consumes more fue l in the
winter tha n in the summe r.
