Adjusting steering wheel position
The steering wheel position can be adjusted
for height and reach .
Fig. 84 Switch for steer ing w heel adjustment
First, adjust the driver's seat correctly.
• To adjust the height, press the switch up/
down . The steering column will continue
moving as long as you are pressing the
switch.
• To move the steering wheel forward or back,
press the switch forward/back . The steering
column will continue moving as long as you
are pressing the switch.
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 detailed information on how to adjust the
driver's sea t, see
Q page 59 .
In vehicles with the memory function*, the
steering column settings are stored together
with the seat position .
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury.
-
On the road 83
-Adjust the steering wheel column only
when the vehicle is not moving to pre­
vent loss of vehicle control.
- Adjust the driver 's seat or steering wheel
so that there is a minimum of 10 inches (25 cm) between your chest and the
steering wheel
~ page 136, fig . 153 . If
you cannot maintain th is m inimum 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
equipment is available .
- If the steering wheel is al igned with yo ur
face, the supplementa l driver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steering whee l is aligned with your
chest.
- Always hold the steering whee l with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal injury
if the driver's airbag deploys.
- Never hold 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.

ter and exit the vehicle by automatically ad­
justing the steering wheel.

Additional information
The engine will switch off in the P, D, N and S
pos itions as well as in manual mode. In the P
position, the engine will also remain off if you
take your foot off the brake pedal. The engine
starts again when you select another selector lever position and take your foot off the brake
pedal.

will stop or not by reducing or increasing the
amount of force you use to press the brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when turning, the engine will not switch off
when the vehicle is stationary. As soon as you
press the brake down harder, the engine will
switch off.

Setting the warning point and steering
wheel vibration
Appl ies to vehicles: with lane assist
You can adjust individual settings in the MMI.
.. Select : I CARI funct ion button > Car systems
control button > Driver assist> Audi lane
assist .
Setting the warning point Early :
With this setting, a warning is provided
before a wheel touches the detected lane
boundary line. The warning depends on the
angle in which the ve hicle is approaching the
line. The distance at which the warning is giv­
e n increases as the angle becomes sharper. If
you dr ive toward a boundary line at a very
sha rp angle, the warning will come just before
a w heel touches the line.
Medium : With this sett ing, the warning point
i s adapted to the cou rse of the road, the lane
width and the speed . You wi ll st ill be warned
if you cross slightly over a dotted line when
driving on curves.
Late: This setting has the same properties as
medium. You will only be warned once a
wheel crosses a detected line.
Setting the steering wheel vibration
The steering wheel v ibration can be set to
Low , Medium or Strong . Selecting each of the
set tings will cause the steering wheel to vi­
brate so you can ch eck the strength of the vi­
bration in that setting.
@ Tips
Your settings are automatically stored and
assigned to the remote contro l key be ing
used.
