Adjusting steering wheel position
The steering wheel position can be adjusted
for height and reach .
Fig. 79 Switch for steer ing wheel 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 seat, see
Q page 55.
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. -
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
Q page 128, fig . 136 . If
you cannot maintain this minimum 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 aligned with your
face, the supplemental driver's airbag
cannot provide as much protection in an
accident. Always make sure that the
steering wheel is aligned with your
chest.
- Always hold the steering wheel 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.

Setting the distance and driving
program
Applies to vehicles: with adaptive cruise co ntrol
Fig. 93 Operating leve r: sett ing the distance
The distance at which the adaptive cruise con­
trol follows a vehicle in front is determined by
time interva ls. A time interval to a vehicle in
front is estab lished and maintained. This pro ­
duces a speed-dependent inte rval. The higher
the speed, the greater the safety interval in
yards (meters)¢ ,&.
Setting the distance
~ Tap the switch to d isplay the current set dis­
tance
¢fig. 93.
~ To increase or reduce the distance by incre­
ments, tap the switch again to the left or
right. The distance between the two vehicles
will change in the instrument cluster dis­
play.
Setting the driving program
~ Select in the MMI: !CAR ! function button >
Car Systems control button > Driver assist >
adaptive cruise control > Driving program .
Setting the distance
When approaching a movi ng veh icle up ahead,
the adaptive cruise contro l system automati­
cally brakes to match that object's speed and
then maintains the stored distance. When this happens, the actual distance may briefly be
less than the stored distance. If the veh icle
ahead accelerates, adaptive cruise control will
also accelerate up to the stored speed.
The higher the speed, the greater the distance
in yards (meters) ¢&. . The
Distance 3 setting
is recommended. The distances
provided are specified va lues.
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
distance may be more or less than these tar­
get distances.
