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.
Easy entry feature
The easy entry feature makes it easier to en­
ter and exit the vehicle by automatically ad­
justing the steering wheel.

with the footbrake . The parking brake elimi­
nates the tendency to creep with a drive range
engaged . As soon as you dr ive off as usual,
the park ing brake is released automatically
and the vehicle starts to move.
Starting on slop es
When starting on inclines, the starting assist
prevents the vehicle from unintentiona lly ro ll­
ing back. The braking force of the parking
brake is not released until sufficient driving
force has been bu ilt up at the wheels.
For safety reasons, the park ing brake is re­
leased automatically only when the dr iv­
er's safety belt is engaged in the buckle.
Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
.. Keep the switch(®) pulled and depress the
acce lerator. The parking brake stays applied
and prevents the vehicle from ro lling back­
ward.
.. You can release the switch (®) once you are
sure that you are develop ing enough for­
ward momentum at the wheels as you de­
press the accelerator.
Depending on the weight of the r ig (vehicle
and tra iler) and the severity of the incl ine, you
may roll bac kwards as you sta rt. You can pre­
vent roll ing backwards by holding the parking
b rake switch (®) p ulled out and acce lerat ing -
just as you would when starting on a hill with a conventional hand brake.
Emergency braking
In the event that the conventional brake sys ­
tem fails or locks .
.. In an emergency, pull the switch(®) and
contin ue to p ull it t o slow your vehicle down
with the parking brake.
.. As soon as you release the switch (®) or ac­
ce lerate, the braking process stops.
If you pull the switch(®) and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy bra king f unct ion is initiated. The vehicle is
braked at all four whee ls by activating the hy­
draulic brake system. The brake performance
is simila r to making an emergency stop
c> .&. .
In order not to act ivate the emergency brak­
ing by mistake, an audib le warning tone (buz­
zer) sounds when the switch(®) is pulled. As
soon as the sw itch (®) is re leased, or the accel­
erato r pedal is depressed, eme rgency braking
stops .
.&, WARNING
E mergency braking should only be used in
a n emergen cy, when t he norma l foot bra ke
has fa iled or the brake pedal is obstructed.
Using the par king brake to perform emer ­
gency b raking will s low your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even with ESC and its associated compo­ nents (ABS, ASR, EDL). In corners and
when road o r weathe r cond itions are bad,
a full brake application can cause the v ehi­
cle to s kid or the rear end to break away -
