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 82.
• 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 242, "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)
L.i (USA models)/ (Canada models)
The Malfunction Indicator Lamp (MIU is part of the On-Board Diag­
nos tic (OBD Ill 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 wo rking
properly.
The warning light illuminates when there is a malfunction in the
engine electronic syst em . Contact your authori zed Audi d ealer and
have the malfunction corrected.
For more information
~ page 27 . •

Instruments and warning/indicator lights
Airbag system ~
This warning/indicator light monitors the airbag and the
tensioner systems.
The GA warning light illuminates for a few seconds each time you
switch on the ignition.
If the
ffl warning light does not go out, or if it illuminates 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
D
The warning/indicator light appears in the event of a
significant loss of air pressure.
The warning/indicator light illuminates for a few seconds after
the ignition is turned on as function check and then goes out.
If the ( 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.

This warning/indicator light monitors the ABS and the
electronic differential lock (EDL).
The A S warning light will come on for a few seconds when the igni­
tion is switched on. The light will go out after an automatic check
sequence is completed.
There is a malfunction in the ABS when:
• the warning/indicator light does not illuminate when you switch
on the ignition.
• the warning/indicator light does not go out after a few seconds.
• the warning/indicator light illuminates while driving.
Without the electronic assistance of the ABS, the brake system will
still respond and brake the car. Have the brake system checked and
restored to its full performance by an authorized Audi dealer as
soon as possible.
For more information regarding the ABS see
=> page 216.
Since any malfunction of the ABS also affects the ESP, that system's
warning symbol.,
=> page 22 will light up along with the n /
(Canada models) warning light.
Unspecific malfunction in the brake system
If both the brake warning light=> page 23 and the c.., warning light
illuminate when the parking brake is released, the likely cause is a
serious malfunction in the brake system beyond an inoperative ABS
=> & . ~

If an unspecific defect in the brake system is indicated, the entire
b rake system is likely to be a ffec ted a nd y ou mus t ex pec t degra ded
brake response and performance .
Since any malfunction of the ABS also effects the ESP, that system's
w arning symbol

General recommendations
Why is your seat adjustment so important?
The safety belts and the airbag system can only provide
ma ximum protection if the front
seats are correctly
a djusted.
There are var ious ways of adjusting the front seats to provide safe
and c omfortable 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 instrumen t pa nel
• your body is proper ly supported to reduce physical stress and
f atigue
• the safety belts and airbag system can offe r maximum protec ­
tion=>
page 768.
I n the fo llowing chapters, you wil l see exact ly how you can best
adjust your seats.
There are special regulations and instructions for instal ling a child
safety seat on the front passenger seat. A lways heed the informa ­
tion regarding child safety provided in=>

& 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 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 ==>
