" a, a,
• Move the steering whee l to the desired po­
s it ion.
• Push the lever aga inst the steering column
u ntil 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 si t 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 whee l.
F or detai led information on how to adjust the
driver's seat, see
o page 63.
The steering wheel can be adjusted even when
the ign ition is turned off. For vehicles wi th
seat memory, the individual positions for the
steering wheel can be stored a long with the
seat position .
A WARNING
Improper use of steering wheel adjust­
ment and improper seating position can
cause serious personal injury .
-Adjust the steer ing whee l co lumn on ly
when the vehicle is not moving to pre­
vent loss of veh icle control.
-
- Adjust the driver's seat or steering whee l
so that there is a m inimum of 10 inches
(25 cm) between your chest and the
steer ing whee l
r::;,page 145, fig . 162 . If
you cannot maintain th is m inimum dis­
tance, the a irbag system cannot protect
you properly.
- 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 whee l is aligned with your
face, the supplementa l dr iver's a irbag
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 with 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 deploys.
- Never hold the steering wheel at the 12 o'clock position or with your hands inside
the steeri ng wheel rim or on the steering
wheel hub. Holding the steer ing wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

206 Intelligent technology
Driving off
When driving off, a lways be sure to keep road
conditions in mind as you accelerate. If one
drive wheel spins because it is on a surface
with less grip, apply
plenty of throttle until
the car starts to
move .
Overheating of brakes
To prevent the disc b rake o f the bra ked wheel
from overheating if subjected to excessive l oads on this whee l, the EDL cuts out tempo­
rarily. The vehicle remains operational and be­
haves in the same way as a vehicle without
EDL.
As soon as the brake has coo led down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the accelerator pedal. Even with the EDL working, the drive
wheels can spin and reduce your ability
to control your car. Risk of crash!
- The increased safety afforded by EDL
does not mean that you can take safety
risks. Always adapt your dr iving style to
the road conditions and traffic situation.
0) Tips
If a fault occurs in the ABS, the EDL is also
not funct ion ing. Thi s is indicated by the
ABS war ning light ¢
page 16.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning when the car is
accelerating.
General notes
The Anti -Slip Regulation System (ASR) is inte­
grated in the electronic stabilization program
( E SP). When the vehicle starts up and acceler­
ates, the wheels are p revented from spinning
by adjusting the engine power to match the amount of grip available
from the road sur­
face.
How the system works
ASR performs automat ically, i .e. w ithout the
driver's intervention. With the aid of the ABS
sensors ¢
page 208, ASR monitors the speed
of the driven whee ls. If the whee ls start to
spin, engine torque is reduced automatica lly
until the tires find enough grip to lock onto
the road surface. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS . If
a malfunction should occur in the ABS, the
ASR will also be out of act ion.
Activating
T he ESP is automatica lly activated when the
engine is started and it performs a se lf-test .
You can activate a deactivated ASR if required by pressing the
¢ page 204, fig. 196 button.
When it is act ivated, the message
ESP/ASR
on
appears briefly in the display .
Deactivating
You can deactivate the ASR if required by
pressing the button (for less than 3 seconds)
¢
page 204, fig . 196. With the ASR deactivat­
ed, the ESP check light comes on, see
¢
page 15 . The message ASR off appears in
the d isplay as well. The ASR can be deact ivat­
ed at any speed.
The ASR s hould normally be activated all the
time . Only in certain exceptional situations
when some slip is desirable does it make
sense to deact ivate the ASR . Examples :
- when driving with tire cha ins
- when driving in deep snow or on loose
ground and
- when rocking the vehicle loose after it has
become stuck.
When the abnormal situation is
over, you
shou ld activate the ASR again .
