AUDI S4 CABRIOLET 2009 Owners Manual

& WARNING
The glass of the inside rearview mirror is layered and contains an
electrolyte to achieve its properties. Be aware of liquid electrolyte
leaking from a broken mirror glass. This liquid can cause irritation
to skin, eyes, and respiratory system. If you get electrolyte in your
eyes or on your skin, immediately rinse with plenty of water. If irri­
tation persists, seek medical attention.
0 Note
Liquid electrolyte leaked from a broken mirror glass will damage any
plastic surfaces it comes in contact with. Clean up spilled electrolyte
immediately with clear water and a sponge.
[ i] Tips
• If you switch off the automatic dimming function on the inside
mirror, automatic dimming of the outside mirrors will likewise be
disabled.
• Check to make sure there are no objects preventing light from
reaching the inside mirror.
• Do not attach any stickers to the windshield in front of the light
sensor, as this would interfere with the automatic operation of the
headlights and the automatic dimming of the inside mirror.•

• Curved (i.e. convex) mirror surfaces increase your field of view.
Remember that vehicles or other objects will appear smaller and
farther away than when seen in a flat mirror . If you use this mirror to
estimate distances of following vehicles when changing lanes, you
could estimate incorrectly and cause an accident.
• If the mirror housing is moved unintentionally (for example,
while parking your vehicle), then you must first fold the mirror elec­
trically. Do not readjust the mirror housing manually. You could
damage the motor which controls the mirror.
[ i] Tips
I f there should be a malfunction in the electrical system, you can
still adjust the outside mirrors by pressing the edge of the mirror. •
Applie s to vehic les : w ith au tomat ica lly dim ming ou ts id e m irrors
Automatic dimming for the outside mirrors *
The outside mirrors dim at the same time as the inside mirror. When
th e ignition is switched on, the mirrors automatically dim
depending on the amount of flight striking the mirrors (such as
headlights shining into the vehicle from the rear). When you switch on the interior light, or when you move the
selector lever into
R (Reverse), the dimming function stops and the
mirrors return to their original condition (not darkened).
[ i] Tips
The automatic dimming feature on the mirrors will not operate
properly if the light shining on the mirrors is blocked by other
objects .•

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=>

the seatbacks are not pushed against the built -in air deflector *
when you run the sea ts back toward the rear of the vehicle and
when you lower the seatback. This can damage the air deflector and
the latching mecha nis m. •

The correct seat position is importan t for safe and relaxed
drivin g.
We recomme nd tha t yo u adjust the dr iv e r's sea t in the
fol lowing ma nne r:

- 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.
- Position the head restraints according to the occupant's
height. For maximum protection, the upper edge of the
head restraints should be at least at eye level, or higher
==>
page 757,fig.156.
& 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 ==>
& in "W hy is
your seat adjustment so important?" on
page 92.

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! •
