Driving
When not being used, a roof rack should be re­moved to decrease the wind resistance of the ve­
hicle. You will save approximately 12% of your
fuel when at speeds from 62- 7 5 mph
(100-120 km/h) .
Save energy
The engine drives the generator, which generates
electricity ; the fuel consumption also increases
with the demand for electricity. Therefore, switch electrical equipment off when you no longer
need it. Examples of equipment that uses a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating* .
@ Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
ind icate improper operation, they would go
unheeded. Extended idling also produces
heat, which could result in overheating or
other damage to the vehicle or other proper-
ty.
@ Note
- Have your vehicle 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 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 wires,
valves, which are designed to protect your
vehicle's Emission Control System and other important vehicle components .
@ Tips
The consumption estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehicle
66
load and speed, road and weather conditions ,
trip length, etc.

ing wheel, check with your authorized Audi
dealer to see if adaptive equipment is avail-
able.
