the battery is weak, the effective range dec reas­
es .
If you need to replace the remote control , or if
you need to have it repaired, you must see your author ized Audi dealer. Only then can you use the
key again .
0) Tips
-If the ignition is sw itched on, the remote
control system is deact ivated.
- The remote control system can be affected
by other systems operating in the same fre­
quency range close to the vehicle, such as
mobile te lephones, television broadcasting
stations, etc.

Clear vision
in the interval wipe position and then come back
a while later and drive off, the rain sensor will re­
activate itself after the vehicle speed has exceed­
ed 4 mph (6 km/h).
The rain sensor* is only activated with the wiper
lever set to position(!). When it starts to rain,
the rain sensor will automatically activate the in­
termittent wiping mode.
To reduce the sensitivity of the sensor, move
switch @ down. To increase the sensitivity, move
the switch up. The higher you adjust the sensitivi­
ty, the faster the sensor will react when it senses moisture on the windshield. The pauses between
wiper turns depend not only on the sensitivity setting, but on the vehicle speed as well.
During brief stops, e.g . at a red light, wiper mo­
tion will automatically be reduced to the next
lower speed . Wipers already turning at low speed
change to intermittent wiping.
When the ignition is turned on, the washer jets
are heated.
A WARNING
- Wiper blades are crucial for safe driving! On­
ly when they are in good condition are they
able to clear the windows properly to pro­
vide uncompromising visibility. Worn or
damaged wiper blades are a safety hazard
¢ page 53, Replacing windshield wiper
blades!
- The light/rain sensor* is only designed to as­
sist and support the driver. It remains en­
tirely the driver's responsibility to monitor outside weather conditions and to manually
activate the wipers as soon as rain or drizzle
reduces visibility through the windshield .
- The windshield must not be treated with
water-repellent materials. They can increase
glare under poor visibility conditions such as
wetness, darkness, or when the sun is low
on the horizon . In addition, they can cause
the windshield wipers to chatter.
(D Note
In freezing or near freezing conditions:
52
- Always check that the wiper blades are not
frozen to the glass before you turn the wip­
ers on. Loosen a wiper blade which is frozen
in place before operating the wipers to pre­
vent damage to the wiper blade or the wiper
motor .
- Do not use the wipers to clear a frosted win­
dow. Using the wipers as a convenient ice
scraper will destroy the wiper blades .
- Before you take your vehicle to an automatic
car wash, make sure you have the wind­
shield wiper system switched off (lever in position
0), otherwise the windshield wiper
system could get damaged in the car wash if
it should suddenly come on.
(D Tips
- The windshield wipers are switched off
when the ignition is turned off. Activate the
windshield wipers after the ignition is
switched back on by moving the windshield
wiper lever to any position.
- Worn or dirty windshield wiper blades cause
smearing, which can affect the operation of
the light/rain sensor*. Check the condition
of your windshield wiper blades regularly.
- The rain sensor is part of the interval wiping
system. Turning off the ignition will also de­
activate the rain sensor . To reactivate the
sensor, switch off the interval wiping func­
tion, then switch it back on again.
- Applies to vehicles with light/rain sensor:
When the wipers are switched on manually
and in rain conditions, the automatic head­
lights* turn on <=>
page 46, Lights or off dur­
ing the day when the wipers are no longer
operating. The automatic headlights* func­
tion is available in this case only when the
light switch is in the "AUTO" position
<=>
page 46, fig. 55.
- Make sure the washer fluid reservoir in the
engine compartment is topped off before
going on a long trip. Look up<=>
page 168
for checking and filling the washer contain­
er.
- The wipers only operate with the hood com­
pletely closed.

Warm and cold Climate controls
Controls
Warm and cold
The climate controls automatically maintain the selected temperature in the vehicle interior through­
out each season .
Fig . 74 Cl imate co ntrols
We recommend the following sett ing :
.. Rotate the knob
Q fig. 74 @ to the right to
switch on the air conditioning .
.,. Set the temperature to 72
°F (22 °() .
.. Press the !AU TO ! Q fig . 74 button .
Using the previously recommended setting is the
qu ickest way to ach ieve a comfortable climate in
the vehicle . This setting should therefore on ly be
changed when personal comfort levels or certain
circumstances req uire it .
The climate controls are a combination of a uto­
mat ic heating and vent ilation systems and a cool­
ing system which dehum idifies and cools the air
ins ide the veh icle .
The climate controls automatically maintain a
temperature once it has been set. The tempera­ ture of the air from the ve nts, fan speed (air vol ­
ume) and air d istr ibut ion are also a utomat ically
adj usted. The system also takes into account
strong sunshine so that manua l adjustment is
n o t necessary. So in almost all ca ses,
automatic
mode
offers the best conditions for the comfo rt of the occupants at a
ll times of the year
Q page 64 .
Please note :
In cooling mode , relative humidity in the interior
is reduced. This prevents the windows from fog­
ging up .
When relative hum idity a nd temperatures o ut­
s ide are high,
condensation can drip from the air
condit ioning evaporator and form a pool of water
under the vehicle . This is normal and not an indi ­
cation of a leak!
When outs ide temperatures are low, the fan does
not switch to a higher speed unti l the coolant has
reached an adequate temperat ure, with the ex ­
cept ion of the defrost setting .
When accelerating a t wide-open throttle, the ai r
condit ioning compressor is temporari ly switched
off to ma intain full eng ine power .
In order to ensure engine coo ling under ext reme
engine loads, the compressor is switched off if
coolant temperatures climb too high .
