c> fig . 96 <=> &_ .
• Move the steer ing whee l to the desired posi­
t ion.
• Push the lever against the steering column
until 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 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
driver's seat, see
c> page 62.
A WARNING
Improper use of steeri ng wheel adjust­
ment and improper seating position can
cause serious personal injury.
- Adjust the steering whee l co lumn on ly
when the veh icle is not moving to pre­
vent loss of veh icle 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 127, fig . 139. If
yo u cannot mainta in this min imum dis- tance, the airbag system cannot protect
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
face, the supplementa l driver's a irbag
cannot provide as much protection in an
accident . Always make sure that the
steer ing wheel is aligned with your
chest.
- Always hold the steering wheel w ith 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 dep loys .
- Never hold the stee ring 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 steering wheel
the wrong way can cause serious injuries
to the hands, arms and head if the driv­
er's airbag deploys.

Electromechanical
parking brake
Operation
The electromechanical parking broke replaces
the hand broke.
Fig. 101 Center co nsole: Parking b rake
.,. Pull on the switch@¢ fig. 101 to apply the
parking brake. The indicator lights in the
switch and • (USA models) . (Cana-
da models) in the instrument cluster illumi­
nate .
"'With the ignition switched on, step on the
brake pedal or the accelerator pedal and
press the switch @at the same time to re­
lease the parking brake. The indicator lights
in the switch and. (USA models)/ . (Can­
ada models) in the instrument cluster go
out.
Your vehicle is equipped with an electrome­
chanical parking brake. The parking brake is
designed to prevent the vehicle from rolling unintentionally and replaces the hand brake.
In addition to the normal functions of a tradi­
tional hand brake, the electromechanical
parking brake provides various convenience
and safety functions .
When starting from rest
- The integral starting assist helps you when
driving by automatically releasing the park­
ing brake ¢
page 88, Starting from rest.
-When starting on inclines , the starting as-
sist prevents the vehicle from unintentional-
ly rolling back. The braking force of the
parking brake is not released until sufficient

driving force has been built up at the
wheels.
E mergency brake function
An emergency brake ensures t hat the vehicle
can be slowed down even if the
normal brakes
fail c::>
page 89, Emergency braking .
8_ WARNING
If a gear or a drive range (automatic trans­
mission) is engaged with the vehicle sta­
tionary and the engine running, you must in no instance accelerate or release the
clutch* carelessly. Otherwise the vehicle
will start to move immediately -risk of an
accident .
(D Tips
-If the parking brake is applied with the
ignition switched off, the indicator lights
i n the sw itch and -(USA models)/ .
(Canada models) in the instrument clus­
ter will go out after a certain per iod of
time .
- Occas iona l noises when the park ing
brake is applied and re leased a re no rma l
and are not a ca use for concern.
- Wh en the vehicle is parked, the parking
brake goes through a se lf-test cycle a t
regular intervals. Any assoc iated noises
are no rma l.
Parking
.. Press the brake peda l to stop the v ehicle .
.. Pull the switch @c::>
pag e 87, fig. 101 to set
the parking brake .
.. Automatic transmiss ion: Move the selector
lever to P .
.. Turn the eng ine off c::>
&_ .
.. Manua l transm ission: Shift into 1st gear .
.. When on incl ines or decli nes, tu rn the steer ­
i ng wheel so th at the vehicle will roll into
the curb if it begins to move .
8_ WARNING
-When you leave your vehicle -even if on­
ly briefly -always remove the ignition
key . Th is applies particularly whe n chil­
dren remain in the vehicle . Otherwise the
children could star t the eng ine , release
the par king brake or operate electrical
equipme nt (e.g. power windows). There
is the risk of an accident.
- W hen the veh icle is locked, no one -pa r­
ticularly not children should remain in
the vehicle . Locked doors make it more
difficult for emergency worke rs to get in­
to the vehicle -putting lives at risk .
· Starting from rest
The starting assist function ensures that the
parking broke is rel eased automatically upon
starting.
Stopping and appl ying parking brake

ing bra ke is automatica lly released and your
vehicle begins to move .
When stopping at a t raffic signal or stopping
in city t raffic on vehicles with an a utomatic
t ransmission, the parking brake can be ap­
plied. The vehicle does not have to be held
with the footbrake . The parking brake elimi­
nates the tendency to creep w ith a dr ive range
engaged. As soon as you drive off as usual,
the parking brake is re leased automat ically
and the vehicle starts to move .
Starting on slop es
When starting on inclines, the starting assist
prevents the vehicle from un in tent ionally roll­
ing back. The braking force of the parking
brake is not released until suffic ient driving
force has been built up at the wheels .

The stored speed a nd the green symbol

shown in the display~
fig. 104 . The display
may vary, depending on the type of display in
your vehicle.
The speed is kept constant by modifying en­ gine power or through an active brake inter­
vention.
A WARNING
- Always pay attention to the traffic around you when the cruise control is in
operation . You are always responsib le for
your speed and the distance between
your vehicle and other vehicles.
On th e road 91
-For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as ice, fog, gravel, heavy ra in and hydro­
plan ing) -risk of accident .
- Turn off the cruise control temporarily when enter ing turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently ''resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's accelera tion.
- I f a brake system malfunction such as
overhea ting occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off . The other cruise contro l functions re­
main active as long as the indicator light
lij;(i )~14 (US models) ;a (Canad ian mod­
els) is on.
(D Tips
- Vehicles with manual transmission: You
can attain the set speed only if the gear
that is currently engaged will allow it, or
if it does not tax the engine and allows it
to run smoothly . Therefore shift into a
higher or lower gear in a timely manner .
- The brake lights illuminate as soon as
the brakes apply automatically.
Chang ing speed
.,. To increase/decrease the speed in incre­
ments, tap the lever in the
0 10 direction

.,. To increase/decrease the speed quick ly, hold
the lever in the
0 10 direction until the de­
sired speed is displayed.
You can also press the accelerator pedal down
to increase your speed, e.g . if you want to
pass someone . The speed you saved earlier
will resume as soon as you let off of the acce l-
erator pedal. .,..
