Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel
.
.,.
Have your vehicle serviced at regula
r
intervals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps 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
consump-
tion
.
Check
your
oil each t ime you
fi
ll
your
t ank.
The amount of oil used is related to engine load
and speed.
It
is normal for the oil consumption of a new en-
g ine to reach its lowes
t
va lue after a cer
t
ain mile
-
age has been d riven
.
You must d rive you
r
vehicle about 3,000 miles
(5,000 kilometers) before you can properly as-
sess o
il
cons umption
.
This a lso applies to fuel consumption and engine
output.

Have your vehicle maintained properly and
in accordance w ith the service recommenda-

Lack of proper m
ai
ntenance as well as
imprope
r
use of the vehicle will impair
t
he
funct ion of the emission control system and
could lead to damage.

Do not a lter or remove any component of
the Emission Cont ro

System unless ap-
proved by the manufacturer.
- Do not a lter
or
remove any dev ice, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emiss ion Control System and other
important veh icle components.

· Fewer short trips
Fuel consumption will always be relatively high
on short trips
.
.,.
Try to avoid dr iving short distances with a cold
eng ine
.
The eng ine and catalytic converter have to reach
their opt imal
operat ing temperature
to reduce
fuel consumpt ion and noxious emissions effec-
tively
.
Just after starting, a cold engine in a mid-s ize car
on ly achieves a fuel economy of 6-8 mi les 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 eng ine is
at its proper operating temperature
and fuel
economy has reached a norma
l
level. So you can
see that you should avo id short
t
rips whenever
poss ible
.
The
outside
temperature is also cr itical in th is re-
gard. Your car consumes more fuel in the winter
than in the summer.
