Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
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 traff ic lights that have
long wa its on red . Turning the engine off fo r
just 30-40 seconds saves more fue l than is
burned st arti ng the engine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . However, wear
and noxious em issions are especially 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 while the engine is
still warming up.

Note
Do not leave engine idling unattended af-
ter starting . If warning lights shou ld come
on to indicate improper operation, they
wou ld 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
authorized 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
consumption.
Check your oil each time you fill your tank.
The amount of oi l used is related to engine
load and speed.
It is normal fo r the oil consump t ion of a new
engine t o reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometers) before you can properly
assess oil consumpt ion.
This also appli es to fue l consumption and en-
gine output.

Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec-
ommendations in your Wa rranty & Main-
t enance boo klet . Lack of proper ma inte-
nance as well as improper use of the ve-
hicle will impair the function of the
emission contro l 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, ign it ion 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 dr iving 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 emis-
sions effectively .
Just after starting, a cold engine in a mid-s ize
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),
