Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
~
Shut the engine off when you are not driving
the vehicle.
~
Do not warm up the vehicle by letting the en-
gine run at idle .
The idling phase is automatically reduced for
veh icles with the Start-Stop-System . It is effi-
cient to switch off the engine in vehicles without
the Start-Stop-System when stopped at railroad
crossings and long red lights . Turning the engine
off for just 30-40 seconds saves more fuel than is
burned by 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 em issions are especially high when
the engine is warm ing up. So you shou ld dr ive
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 after
starting. If warning lights should come on to
indicate improper operation, they would go
unheeded. Extended idling also produces
heat, wh ich could result in overheating or oth-
er 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 intervals.
By having your vehicle regularly serviced by an
Audi dealer helps to ensure that it runs properly
and economica lly. The condition of your vehicle
not on ly 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 oil used is related to engine load
and speed.
Driving
and the environment
It is normal for the oil consumption of a new en-
gine to reach its lowest value after a certain mile-
age has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly as-
sess oil consumption .
This also applies to fue l consumption and engine
out put .
CD
Note
- Have your veh icle maintained properly and
in accordance with the service recommenda-
tions in your Warranty & Maintenance book-
let . Lack of proper maintenance as well as
improper use of the vehicle will impair the
function of the em ission 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, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components .
Fewer short trips
Fuel consumption will always be relatively high
on short trips .
~
Try to avoid dr iving short distances w ith a cold
eng ine.
The engine and catalytic converter have to reach
their optimal operating temperature to reduce
fuel consumpt ion and noxious em issions effec-
t ively.
Just after starting, a cold engine in a mid-size car
only 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 t o 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 avoid short trips whenever
possibl e.
