The engine drives the generator, wh ich generates
electricity; the fue l consumption also increases
with the demand for electricity. Therefore, switch
e lectrical equipment off when you no longer
need it. Examples of equipment that use a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD 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, wh ich could result in overheat ing or
other damage to the vehicle or other p roper-
ty.
CD Note
-Have your vehicle maintained properly and
i n accordance with the service recommenda­
tions in your Warranty
& Ma intenance book­
l et. Lack of proper maintenance as well as
i mproper 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 shie lds, 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
load and speed, road and weather conditions

& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­

with the selector lever in the P position .
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off .
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
reasons :
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.

'"" .... 0 0 :c ' Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­ my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trailer operation mode
c:> page 89, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location . Use only a trailer hitch with a re­
movable ball mount. Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bolts remain securely fastened.
When you are not towing a trailer, remove the trailer hitch ball mount . This prevents the hitch
from causing damage should your vehicle be
struck from behind
£:=? .&, .
Trailer towing
Trailer brakes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regula­
tions.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system.
Safety chains
Always use safety chains between your vehicle and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Audi dealer for correct wiring,
switches and relays .
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear .
.,&. WARNING
-After removing the trailer hitch, do not store
it in your vehicle. In case of sudden braking,
the hitch could fly forward and injure you or
your passengers.
