On the road
Steering
Adjusting the steering wheel column
The height and reach of the steering wheel can be
adjusted.
First, adjust the driver's seat correctly.
Fig . 135 Lever under
the steering column
-Push the lever~ fig. 135 -Arrow- ~& .
- Move the steering wheel to the desired position.
- Push the lever against the steering column unt il it locks.
Th ere mus t be at least 10 inches (25 cm) betw een your br eastbone
and the center of the steering wheel. If you cannot sit more than 10
inches (25 cm) from the steering wheel, we recommend that you
investigate whether adaptive equipment is available to help you
reach the pedals and increase your seating distance from the
steering wheel.
For detailed information on how to adjust the driver's seat, see
=> page 96, "Power seat adjustment" .
& WARNING
Improper use of steering wheel adjustment and improper seating
position can cause serious personal injury .
• Adjust the steering wheel column only when the vehicle is not
moving to prevent loss of vehicle control.
• Always make sure that the adjustment lever is securely pushed
up so that the position of the steering wheel cannot be changed
unintentionally when the vehicle is moving.
• Adjust the driver's seat or steering wheel so that there is a
minimum of 10 inches
125 cm) between your breastbone and the
steering wheel=> page 148, fig.
154. If you cannot maintain this
minimum distance the airbag system cannot protect you properly.
• If physical limitations prevent you from sitting 10 inches
125
cm) or more from the steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is available.
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in an
accident. Always make sure that the steering wheel is pointed
towards your chest.
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag
inflates.
• Never hold the steering wheel at the
12 o'clock position or with
your hands at other positions 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
driver's airbag inflates. •
