Seats and storage
General information
Why is your seat adjustment so important?
The safety belts and the airbag system can only
provide maximum protection if the front seats are correctly adjusted.
There are various ways of adjusting the front
seats to provide safe and comfortable support
for the driver and the front passenger. Adjust
your seat properly so that:
- you can easily and quickly reach all the switches
and controls in the instrument panel
- your body is properly supported thus reducing
physical stress and fatigue
- the safety belts and a irbag system can offer
maximum protection ¢
page 128.
In the following sections, you will see exactly
how you can best adjust your seats.
There are special regulations and instructions for installing a child safety seat on the front pas­
senger's seat. Always follow the information re­
garding child safety provided in¢
page 150,
Child safety.
A WARNING -
Refer to¢ page 111, Driving safety for im­
portant information, t ips, suggestions and
warnings that you should read and follow for
your own safety and the safety of your pas­ senge rs.
A WARNING
Incorrect seating position of the dr iver and all
other passengers can resu lt in serious person­
al injury.
- Always keep your feet on the floor when the
vehicle is in motion -never put your feet on
top of the instrument pane l, out of the win­
dow or on top of the seat cushion. This ap­
plies especially to the passengers . If your
seating pos it ion is incorrect, you increase
the risk of injury in the case of sudden brak­
ing or an accident. If the airbag inflates and
Seat s and stor age
the seating position is incorrect, this cou ld
result in personal injury or even death.
- It is important for both the driver and front
passenger to keep a distance of at least
10 inches (25 cm) between themselves and
the steering wheel and/or instrument panel.
If you're sitting any closer than this, the air­
bag system cannot protect you properly. In
addition, the front seats and head restraints must be adjusted to your body height so
that they can give you max imum protect ion.
- Always try to keep as much distance as pos­
sible between yourself and the steer ing
wheel or instrument pane l.
- Do not adjust the driver's o r front passeng­
er 's seat while the veh icle is moving. Your
seat may move unexpectedly, causing sud­
den loss of vehicle control and persona l in­
jury.
If you adjust your seat whi le the vehicle
is moving, you are out of position.
Driver's seat
The correct seat position is important for safe
and relaxed driving.
We recommend that you adjust the dr iver's seat
in the following manner:
"' Adjust the seat in fore and aft direction so that
you can eas ily push the pedals to the floor
while keeping your knees slightly bent¢.&,
in
Why is your seat adjustment so important? on
page 53.
"' Adjust the seatback so that when you sit with
your back against the seatback, you can still
grasp the top of the steering wheel.
"' App lies to veh icles w ith adjustable head re­
straints: Adjust the head restraint so the upper
edge is as even as possible with the top of your
head.
If that is not possible, try to adjust the
head restra int so that it is as close to th is posi­
t ion as possible ¢

Driving
Steering
Manually adjustable steering wheel
The steering wheel position is fully adjus table up
and down and forward and back .
Fig. 74 Lever under the st eering column
First, adjust the driver's seat correctly.
• Pull the lever~
fig. 74 ~ .&, .
• Move the steering wheel to the desired posi­
tion.
• Push the lever against the steering column un-
til it locks.
There must be at least 10 inches (25 cm) be­ tween your chest and the center of the steering
wheel. If you cannot sit more than 10 inches (25
cm) from the steering wheel, see if adaptive
eq uipment is available to help you reach the ped­
als and increase the distance from the steering
wheel.
Fo r detailed information on how to adjust the
driver's seat, see
~ page 54 .
.&_ WARNING
Improper use of steering wheel adjustment
and improper seating position can cause seri­
ous personal injury.
- Adjust the steering wheel column only when
the vehicle is not moving to prevent 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 112, fig. 118 . If you cannot
-
Driving
maintain this minimum distance, the airbag
system cannot protect you properly.
-If phys ical limitations prevent you from sit­
ting 10 inches (25 cm) or more from the
steering wheel, check with your authorized
Audi dealer to see if adaptive equipment is
available.
- If the steering wheel is aligned with your
face, the supplemental driver's airbag can­
not provide as much protection in an acci­
dent. Always make sure that the steering
wheel 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 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 driver's airbag
deploys .

bra ke is automatically released and yo ur vehicle
beg ins to move. .,_

When stopping at a traffic signal or stopp ing in
city traffic on vehicles with an automatic trans­ miss ion, the park ing brake can be applied . The
vehicle does not have to be held with the foot­ brake. The parking brak e eliminates the tendency
to creep with a drive range engaged . As soon as
you dr ive off as usual , the parking brake is re­
leased automatically and the veh icle starts to
move.
Starting on sl opes
When starting on inclines, the start ing ass ist pre­
vents the vehicle from unintentionally rolling back. The braking force of the parking brake is
not released until sufficient driv ing force has
been b uilt up at the whee ls .
@ Tips
For safety reasons, the park ing brake is re­
leased automatically only when the dr iver's
safety belt is engaged in the buckle.
Emergency braking

Speed warning system
Overview
The speed warning system helps you to keep your
driving speed below a set speed limit.
T he speed warning system warns if the driver ex ­
ceeds a previous ly stored maximum speed . A
warning tone will sound as soon as the veh icle
speed exceeds the set speed by about 3 mph
(3 km/h) . At the same t ime, a warning symbol
appears in the display . The symbol's appearance
mig ht be different in some models .
The speed warn ing system has two warning
t hr esholds that funct ion independent ly of each
othe r and t hat have somewhat d ifferent pu rpos­
es:
Speed wa rning 1
You can use speed warning 1 to set the maximum
speed wh ile you are driving. Th is sett ing will re­
main in effect until you turn off the ign ition, as ­
suming that you have not changed or reset th e
setting.
The . (USA models)/ . (Canada models)
speed warning symbo l in the warn ing 1 disp lay
appears when you exceed the maximum speed .
It
goes out when the spe ed falls be low the stored
ma ximum speed.
The speed warn ing symbol will also go out if the
speed
exceeds the stored maximum speed by
more than about
25 mph (40 km/h) for at least
10 seco nds. The stored maxim um speed is dele t-
ed.

Automatic transmission
vehicle when the engine is running, activate
the parking brake and move the selector lev­
er to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must
keep your foot on the brake when the engine
is running and the selector lever is in D/S or
R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An indicator lamp
5] illuminates
and a driver message appears¢
page 86
when the clutch is overloaded.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
¢page 187. Otherwise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
-When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected. This can cause the transmission to
overheat and can damage it. Activate the
84
parking brake or press the brake pedal to
prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances .
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle .
Hill descent control
The hill descent control system assists the driver
when driving down declines.
Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
that is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitation s.
It may still be necessary to adjust the
speed with the brakes .
Hill descent control switches off once the decline
level s out or you press the accelerator pedal.
On vehicles with the cruise control system*
¢
page 78, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes.
