-You should not use the recirculation mode
for an extended period of time, because no
fresh a ir is drawn in and the windows can

increases the risk of an accident .
-Individuals with reduced sensitivity to pain
o r temperature could develop burns when
using the seat heating function. To reduce
the risk of injury, these indiv iduals should
not use seat heating.
(D Note
To avoid damage to the heat ing elements in
the seats, do not kneel on the seats or place
heavy loads on a small area of the seat.
@ Tips
-The setting for the seat heating on the driv­
er's side is ass igned to the key that is in use .
-If the front passenger's seat heating is

Driving
When not being used, a roof rack should be re­
moved to decrease the wind resistance of the ve­
hicle. This will save you approximately 12% fuel
at speeds from 62
-75 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* .
(D 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, which could result in overheating or
other damage to the vehicle or other prop­ erty.
- 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 consumpt ion 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,
trip length, etc.

Steering
Adjusting the steering wheel position
The steering wheel position is fully adjustable up
and down and forward and back.

.. Tilt the lever -c> fig. 83 downward¢ ,&..
.. Bring the steering wheel into the desired posi­
tion.
.. Push the lever against the steering column un­

A WARNING
Incorrect use of the steering wheel adjust­
ment and an incorrect seating position can
cause serious injuries.
- Only adjust the steering column when the veh icle is stationary so that you do not lose
control of the vehicle.
-
-Adjust the driver's seat or steer ing wheel so
that there is at least 10 inches
(25 cm) dis­
tance between your chest and the steering
wheelr::!>page250, fig. 217. If you do not
maintain this distance, the airbag system
will not be able to provide its full protec­ tion.
c:> page 250, fig. 217.
- If your physical characteristics prevent you
from sitting at least 10 inches
(25 cm) or
more away from the steering wheel, see if
an authorized Audi dealer or authorized
Audi Service Facility can provide adapters that will help.
- If your face is level with the steering wheel,
the airbag does not provide as much protec­
tion during a collision. Always make sure
that the steering wheel is level with your
chest.
