Instruments and warning/indicator lights
& WARNING
• Failure to heed warning lights and other important vehicle
information may result in serious personal injury or vehicle
damage .
• Whenever stalled or stopped for repair, move the vehicle a safe
distance off the road, stop the engine, and turn on the emergency
flasher
=> page 79.
• The engine compartment of any motor vehicle is a potentially
hazardous area. Before you check anything in the engine compart­
ment, stop the engine and let it cool down . Always exercise
extreme caution when working under the engine hood
=> page 265 , "Engine compartment"
[ i] Tips
Many functions are monitored by the Auto-Check system
=> page 28. Malfunctions or faults will be identified either with a red
symbol (priority 1 - Danger!) or with a yellow symbol (priority 2 -
Warning). •
Malfunction Indicator Lamp (MIL)
~ (USA models)/ 0 (Canada models)
The Malfunction Indicator Lamp (MIU is part of the On-Board Diag ­
nostic (OBD II) system. The
symbol ~ lights up when the ignition is
turned on and will turn off after the engine has started and has
settled at constant idle speed . This indicates that the MIL is working
properly.
The warning light illuminates when there is a malfunction in the
eng ine electronic system. Contact your authorized Audi dealer and
have the malfunction corrected.
For more information
=> page 27. •
Airbag system ~
This warning/indicator light monitors the airbag and the
tensioner systems.
The I warning light illuminates for a few seconds each time you
switch on the ignition.
If the
~i warning light does not go out, or if it illum inates while you
are driving, or if it starts to flash, then there is a malfunction some ­
where in the system. If the light does not illuminate when you
switch on the ignition, this also means there is a malfunction.
& WARNING
If you have a malfunction in the airbag system, contact your autho­
rized Audi dealer immediately. Otherwise the airbag or the belt
tensioner may not work properly in an accident. •
Tire pressure monitoring system -telltale
indicator lamp
U)
The warning/indicator light appears in the event of a
significant loss of air pressure.
The (1) warning/indicator light illuminates for a few seconds after
the ignition is turned on as function check and then goes out.
If the
(l) symbol appears, pressure is too low in at least one tire.
When the system detects a malfunction, the warning/indicator light
will flash for approximately one minute and then remain continu­
ously illuminated. This sequence will continue upon subsequent
vehicle starts up as long as the malfunction exists. Contact your
authorized Audi dealer and have the malfunction corrected.

Seats and storage
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 several different ways you can adjust the driver's seat and
the front passenger's seat so that it conforms to your body size. It is
especially important that the seat be adjusted 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 187
In the following chapters, 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 passenger's seat. Always heed the informa ­
tion regarding child safety provided
in => page 210, "Child Safety".
& 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
Controls and equip ­
ment
Seats and storage
& 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
cml between themselves and
the steering wheel and/or instrument panel. If you're sitting any closer than this, the airbag system can protect you properly. In
addition to this, 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
knee 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.
...,

Seats and storage
-Position the head restraints according to the occupant's
height. For maximum protection, the upper edge of the
head restra ints should be at least at eye level, or higher
=:> page 105, fig. 106.
& 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 unfolding, do not
sit any closer to the instrument panel than necessary and
always properly wear the three point safety belt provided.
We recommend that you adjust the driver's seat in the
following manner:
-Adjust the front passenger seat into the rearmost posi­
tion of the fore and aft adjustment range
=:> & in "W hy
is your seat adjustment so important?" on page
95.
-Adjust the backrest to the upright position . Do not
recline.
-Adjust the head restraint so the upper edge of the
restraint is level with the top of your head, but no lower
than eye
level =:> page 105, fig. 106.
-Place your feet on the floor in front of the passenger's
seat. •
Adjusting the front seats manually
