Steering
Adjusting the steering wheel column
The steering wheel position can be continu­
ously adjusted in height and distance .
Fig. 80 Lever under the steer ing colu mn
~ Push the lever Q fig. 80 -Arrow- ¢&_ .
~ Move the steer ing whee l to the desired posi ­
tion.
~ Push the lever against the steering column
until it locks.
There must be at least 10 inches (25 cm) be­
tween your chest and the center of the steer­ ing wheel. If you cannot sit more than 10 in­
ches (25 cm) from the steering wheel, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
For detai led informat ion on how to adjust the
driver's seat, see
Q page 61.
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
- Adjust the steering wheel column only
when the veh icle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering wheel
so that there is a min imum of 10 inches
(25 cm) between your chest and the
steering wheel¢
page 92, fig . 99. If
you can not maintain this min imum dis­
tance, the airbag system cannot protect
you properly.
- If physical limitations prevent you from
sitt ing 10 inches (25 cm) or more from
the steering wheel, check with your au­
thorized Audi dealer to see if adaptive equ ipment is ava ilable .
- If the steer ing wheel is aligned with your
face, the supplemental dr iver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steer ing whee l is aligned with your
chest.
- Always hold the steering wheel w ith your
hands at the 9 o'clock and 3 o' clock posi­
tions to reduce the risk of persona l injury
if the driver's airbag dep loys .
- Never ho ld the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on the steering
wheel hub . Holding the steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

Starting and stopping
the engine
' Starting the engine
The engine can only be started with an origi­
nal Audi key .
.,. Se t the par king brake.
.,. Move the selector lever in P or
N q .&_ .
.,. Turn the ignition key to position @
~ page 72, fig. Bl -do not depress the gas
peda l when starting the engine!
.,. Let go of the key as soon as the engine
starts .
A cold engine may at first be loud after it has
been started. This is due to the hydraulic
valves bu ild ing up the oil pressure. Th is nor­
mal and no need for concern .
If the engine does not start immediately, stop
trying after 10 seconds and then try to restart
the engine about 30 seconds later.
A WARNING
-Never start or let the eng ine run in a con-
fined o r enclosed area . Exhaust fumes
from the engine co ntain carbon monoxide,
a colorless and odo rless gas. Ca rbon mon ­
oxide can be f atal if inhaled.
- Never leave the engine id ling unattend­
ed. An una ttended veh icle w ith a runn ing
engine poses a danger o f personal injury
or theft .
(D Note
-Avo id high engine speeds, fast accelera ­
tion or heavy engine loads while the en­
gine is still cold. This could damage the
engine.
- The e ngine cannot be started by pushing
or towing the vehicle . .,..

7 4 On the road
@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
veh icle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Maintain moderate speed until the
engine is comp letely warm. Remember,
the engine performs best at operating
temperature.
Stopping the engine
• Turn the ign ition key to position@
~ page 72, fig. 81.
&_ WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake if
necessary. Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injuries.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the engine and removed the
ignition key . The radiator fan can also
turn on again if the engine coolant heats up because of intense sunlight or heat
build-up in the engine compartment.
(D Note
Do not stop the engine immediate ly after
hard or extended driving. Keep the engine
running for approximately two minutes to
prevent excessive heat build-up.
