low ground clearance . The fault
should be corrected as soon as possib le by an authorized Audi
dea ler .
• If the warning/indicator light flashes, you should not drive the
vehic le . The flashing warning/indicator light points to an extreme

normal, the warning/indicator lights stop flashing, and you can
drive away .

General recommendations
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 airbag system can offer maximum protec ­
tion =>
page 220.
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 seat on the front passenger's seat. Always follow the information
regarding child safety provided in=>
page 245, "Child Safety".
L1}. WARNING
Incorrect seating position of the driver and all other passengers
can result in serious personal injury.
• Always keep your feet on the floor when the vehicle is in motion
- never put your feet on top of the instrument panel, out of the
window or on top of the seat cushion. This applies especially to
the passengers. If your seating position is incorrect, you increase
the risk of injury in the case of sudden braking or an accident. If
& WARNING (continued)
the airbag inflates and the seating position is incorrect, this could
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 airbag 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 maximum protection.
• Always try to keep as much distance as possible between your­
self and the steering wheel or instrument panel.
• Do not adjust the driver's or front passenger's seat while the
vehicle is moving. Your seat may move unexpectedly, causing
sudden loss of vehicle control and personal injury.
If you adjust
your seat while 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 driver's seat in the
following manner:
- Adjust the seat in fore and aft direction so that you can
easily push the pedals to the floor while keeping your
knees slightly bent=>
& in "Why is your seat adjustment
so important?".
Adjust the seatback so that when you sit with your back
against the seatback, you can still grasp the top of the
steering wheel. _..

- Position the head restraint according to the occupant's height=>
page 91. For maximum protection, the top of
the head restraint should be at least at eye level, prefer­
ably higher and ideally level with the top of the head
=>
page 205, fig. 220.
& WARNING
Never place any objects in the driver's footwell. An object could
get into the pedal area and interfere with pedal function. In case
of sudden braking or an accident, you would not be able to brake
or accelerate. •
Front passenger's seat
Always move the front passenger seat into the rearmost
position.
To avoid contact with the airbag while it is deploying, do not
sit any closer to the instrument panel than necessary and
always wear the three-point safety belt provided adjusted
correctly. We recommend that you adjust the passenger's
seat in the following manner:
- Move the front passenger seat into the rearmost position
of the fore and aft adjustment range=>
& in "Why is
your seat adjustment so important?" on
page 86.
-Bring the backrest up to an (almost) upright position. Do
not ride with the seat reclined.
- The ideal position for the head restraint is with the upper
edge of the restraint level with the top of your head
=>
page 91. You should not lower the top of the restraint
below the level of your eyes.
Con tro ls and eq uip­
ment
Seats and storage
- Place your feet on the floor in front of the passenger's
seat. •

Adjusting the angle of the seat back
- Push the switch ~ page 89, fig. 85 forward or to the rear
in the direction of the arrow to adjust the angle of the
seat back
~ & .
Adjusting the angle of upper seatback section
- Push the switch ~ page 89, fig. 86 forward or to the rear
to adjust the angle of upper seatback section~& .
& WARNING
• Never adjust the seatback while the vehicle is moving. If you
adjust your seat while the vehicle is moving, you are out of posi­
tion. Never adjust the seatback when the vehicle is moving .
• To reduce the risk of injury in the case of sudden braking or
accident, front passengers must never ride in a moving vehicle
with the seatback reclined. Safety belts and the airbag system only offer maximum protection when the seatback is upright and
the safety belts are properly positioned on the body. The more the seatback is reclined, the greater the risk of personal injury from an
incorrect seating position and improperly positioned safety
belts .•
Lumbar support
The lumbar support can be adjusted to fit the natural
curvature of the occupant's spine.

Fig . 87 Power seat:
Switch shell for lumbar
support
- Push the forward depression on the switch shell to
increase the curvature.
- Push the
rear depression on the sw itch shell in order to
decrease the curvature.
Adjusting the height
-Push the top depression on the switch shell to move the
support to a
higher position in the backrest.
- Push the
bottom depression on the switch shell to move
the support to a
lower position in the backrest.
The lumbar support is particularly effective in supporting the
natural curvature of the spine so that the seating position is more
comfortable over long distances. .,
