Seats and stor age
A WARNING
- To reduce the risk of an accident, on ly adjust
the front seats when the vehicle is station­
ary.
- The power adjustment for the front seats al­
so works w ith the ignition switched off or
with the ignition key removed . T o reduce
the risk of injury, chi ld ren should never be
left unattended in the vehicle for this rea­
son.
- Exercise caution when adjusting the seat
height. Uns uperv ised or careless seat ad­
justment can p inch f ingers or hands, wh ich
increases the risk of injury.
- T he front seat backres ts m ust not be re­
clined too far back when driving, because
this impairs the effectiveness of the safety
belts and airbag system, which increases
the risk of injury.
(D Tips
The massage function* switches off a utomat i­
cally after approximately 10 min utes.

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.
Fig . 83 Steering column : steering column adjustment lever
.. Tilt the lever -c> fig. 83 downward¢ ,&..
.. Bring the steering wheel into the desired posi­
tion.
.. Push the lever against the steering column un­
til it is secure.
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.

-Always hold the steering whee l with your
hands in the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of injury if the airbag
deploys.
- Never hold the steer ing wheel in the 12
o'clock position or with both hands on the
rim or the center of the steer ing wheel.
Holding the steering wheel incorrectly s ig­
nificantly increases the risk of in jury to the
hands, arms and head if t he a irbag dep loys.

The locked steering helps prevent vehicle theft.
A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use more force to turn or brake . Because you
cannot steer and brake as you usually
would, this co uld lead to accidents and seri-
. . . ous mJunes .

wise, the engine could be started or electri­
cal equipment such as the power windows
could be operated. This can lead to serious
injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll unintentionally .
(D Note
If the engine has been under heavy load for
an extended period of t ime, 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
for at idle
for approximately two minutes be­
fore shutting it
off.
@ 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 sw itched
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.
