---------------------CONTROLS AND
EQUIPMENT
General notes
• Vehicle heating is depend upon tne tem­
perature of the engine coolant -therefore,
your vehicle interior will warm uponly when
the engine has reached its operating tem­
perature.
When the ambient temperature is too low,
the fan only switches to high speed modes
when the coolant has reached a sufficiently
high temperature, or when the ® button
has been depressed.
• Keeping the air intake slots in front of the
windshield free from ice, snow and debris
helps to make sure that the climate control
system will work properly.
• When the air conditioner compressor is
on it reduces both the temperature and the
humid ity of the air inside the vehicle. This
prevents the windows from fogging up.
• The air conditioner works best with the
windows and power roof* closed. •
If the inside temperature is very high af­
ter the vehicle has been parked in the sun,
open windows and allow the hot air to es­
cape before switching on the air condi­
tioner.
• The dust and pollen filter will prevent
dust and pollen etc. in the outside air from
entering the car. Switch to air recirculation
to prevent unpleasant fumes from entering
the vehicle.
If water drips under the
vehicle ...
At high outside temperatures and humidity,
condensation may drip from the evaporator.
This is normal and does not indicate a leak.
If the airflow is not cool ...
• At low ambient temperatures the air con­
ditioner compressor switches off automati­
cally. The compressor cannot be switc hed
on again in this case, even by pressing the
AUTO button. •
The air conditioner may switch itself off
temporarily to ensure sufficient engine
cooling when the engine is running at full
load.
The air conditioner will also be switched off
temporarily in the kick-down function. See
page 109.
• Check the air conditioning fuse on the
fuse p imel -see page 27 4. Have it replaced,
if necessary.
• If you suspect that the air conditioner is
damaged, for instance after an accident,
switch to the ECON and have the system
examined immediately for leaks or other
damage.

CONTROLS AND
EQUIPMENT--------------------
Maintenance
• For maximum efficiency of the air condi­
tioner the dust and pollen filter elements
must 'be replaced at the intervals indicated
in the Maintenance Schedule.
• The condenser must be checked regu­
larly to make sure it is clean. If it becomes
obstructed by dirt or insects, spray 1t clear
with water.
• Repairs to the Audi air condition­
ing system require specialized
knowledge and special tools.
If the system is not functioning
properly, contact your Audi Dealer.
16 8 Power roof*
The roof will slide open or tilt up at the rear
as required. When the ignition is on it can be
opened and closed by turning the rota�
control next to the interior light. The roof 1s
tilted open or closed by pressing or pulling
the control -see illustration.
When turning the ignition off, however, the
sunr oof can still be operated as long as the
driver's and front passenger's door are
closed. When either door is opened, sliding
roof operation will be deactivated .
Always close the roof completely if you are
going to park your vehicle and leave. �W
ARNING
Be careful when closing the power
roof 1 tilt roof. Not paying atten­
tion could cause you or others to
be caught and injured as the roof
closes. To help avoid injuries
caused by closing the roof, always
take your key whenever you leave
your vehicle.

VEHICL E
CA RE-------------------------
If the engine compartment is cleaned at any
time with grease removing solutions 1 ), or if
you have the engine washed, the antK:orr sion treatment is almost always removed
as well. It is therefore essential to ask: for a
long-lasting corrosion protection of all sur­
faces, seams, joints and components in the
engine compartment.
c£> If you must rinse off gasoline, oil
residue or grease while you are
washing your engine, then tha dirty
water should be run through an oil
separator filter. We recommend that
you have your engine washed at a
qualified workshop or service sta­
ti on.
11 Use only
the correct cleaning solutions.
Never use gasoline or Diesel.
220 Chassis
The lower body shell of your Audi is also
thoroughly protected against corrosion.
Any damage to the undercoat ing caused by
road hazards should be repaired promptly.
g WARNING
Do not apply additional undercoat­
ing or rustproofing on or near the
exhaust manifold, exhaust pipes.
catalytic converter or heat shields.
During driving, the substance
used for undercoating could over­
heat and cause a fire. Body
cavity sealing
All body cavities which could be affected by
corro sion have been given thorough protec­
tion at the factory.
This sealing does not require any inspection
or additional treatments. If any wax should
seep out of the cavity when the ambient
temperature is high, it can be removed with
a plastic scraper and a suitable solvent.
c£> If you use benzine for removing
the wax, keep sparks, flame and
ligh ted cigara ttas away. Nsver
dump benzine on the ground, into
open streams or down sewage
dr ains.
Be sure to observe all safety and en­
vi ronmental regulations.

VEHICLE
CARE---------------------------------------------------
Maintenance
Yo ur vehicle has been designed to help
keep maintenance requirements to a mini­
mum.
However. a certa in amount of regular main­
tenance is still necessary to assure your ve­
hic le's safety, economy and reliabili ty.
c£> By regularly maintaining your
vehicle, you help make sure that
emission standards are maintai ned,
thus minimizing adverse effects on
the envir onment.
For detailed vehicle maintenance consult
your Maintenance booklet.
Under difficult operating condi­
tions, for example at extremely low out­
side temperatures, in very dusty regions,
when towing a trailer very frequently, etc.,
some service work should be performed
between the intervals specified.
This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
228 Important
considerations for
you and your vehicle:
The increasing use of electr onics, sophisti­
cated fuel injection and emission control
systems, and the generally increasing tech­
nical complexity of today's automobiles,
have steadily reduced the scope of mainte­
nance and repairs which can be carried out
by vehicle owners. Also, safety and en­
vironmental concerns place very strict
limi ts on the nature of repairs and adjust­
ments to engine and transmission parts
which an owner can perform . Main
tenance, adjustments and repairs usu­
ally require special tools, testing devices
and other equipment available to specially
trained workshop personnel in order to as­
sure proper performance, reliability and
safety of the vehicle and its many systems.
Impr oper maintenan ce, adjustments and
repairs can impair the operation and reliabil­
ity of your vehicle and even void your ve­
hicle warranty. Therefore, proof of servicing
in accordance with the maintenance
schedule may be a condition for upholding
a possible warranty claim made within the
warranty period.
Above all, operational safety can be ad­
versely affected, creating unnecessary
risks for you and your passengers.
