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 whee l, see if
adaptive equipment is available to help you
reach the pedals and increase the distance
from the steering wheel.
F or detai led information on how to adjust the

you proper ly.
- If physical limitations prevent you from
sitting 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
