irechnical data

• Before you take your vehicle to an automatic car wash , make sure
you have the windshield wiper system switched off !lever in position
Ol, otherwise the windshield wiper system could get damaged in the
car wash if it should suddenly come on.
[ i] Tips
• The rain sensor is part of the interval wiping system. Turning off
the ignition will also deactivate the rain sensor . To reactivate the
sensor, switch off the interval wiping function, then switch it back
on again.
• Worn or dirty windshield wiper blades cause smearing, which
can affect the operation of the light/rain sensor*. Check the condi­
tion of your windshield wiper blades regularly .
• 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 53, "Sensor activated head- and tail light
control" or off during the day when the wipers are no longer oper ­
ating . The automatic headlights* function is available in this case
only when the light switch is in the "AUTO" position~
page 53,
fig. 48.
• Make sure the washer fluid reservoir in the engine compartment
is topped off before going on a long trip. Look up~
page 241 for
checking and filling the washer container .
• The wipers only operate with the hood complete ly c losed .•

& WARNING
Wiper blades are crucial for safe driving! Only in good condition
are they able to clear the windows properly to provide unre­
stricted visibility. Worn or frayed wiper blades are a safety hazard!
=> page 67, "Replacing front wiper blades"
(D Note
In freezing or near freezing conditions:
• Always check that the wiper blades are not frozen to the glass
before you turn the wiper on. Loosen a wiper blade which is frozen
in place before operating the wiper to prevent damage to the wiper
blade or the wiper motor.
• Do not use the wiper to clear a frosted window . Using the wipers
as a convenient ice scraper will destroy the wiper blades.
[ i J Tips
For better rearward vision when parking, the rear window wiper is
automatically activated one time when the windshield wipers are
switched on and reverse gear is engaged. •
Applies to vehic les: w ith head light washer system
Headlight washer system
The headlight washer system cleans the headlights.
-Operate the windshield wiper/washer system=> page 63,
fig. 64 © with the headlights turned on by holding the
lever for longer than one second.
The washer jets extend forward out of the front bumper driven by
water pressure to spray the front headlights with water.
You should inspect the headlights regularly (for example when refu­
eling) and clean off any solid dirt or insects from the lenses. To
ensure the system works properly in winter, keep the washer jets
free of snow and remove any ice using a de -icing spray. •
Service position
Replacing the windshield wiper blades is only possible
when you move the wiper arms into the service position. In
order to use the windshield wipers, the hood must be
completely closed. When there is a risk of frost, make sure
that the wiper blades are not frozen to the windshield.
Switch the ignition on.
Act ivate the service position by way of the driver infor­
mation system =>
page 23.
(D Note
Never drive your vehicle when the windshield wiper arms are in the
service position and pulled away from the windshield. When you
drive faster than 4 mph (6 km/h), the wiper arms automatically
return back to the park position and could cause paint damage to
the engine hood!
[ i] Tips
• You can also turn on the service position, for example, if you
want to protect the windshield from icing by using a cover.
• Th e service position moves to
off automatically when you
operate the windshield wiper lever, or speed exceeds 4 mph
(6 km/h). •

& WARNING (continued)
• For safety reasons, the windshield wiper blades should be
replaced once or twice a year. •

Automatic dimming function
The automatic dimming function is activated every time the ignition
is turned on. The green indicator light is lit to indicate auto dimming

When dimming is activated, the inside mirror will darken
automati­
cally
in response to the amount of light striking the mirror (such as
headlights from rearward approaching vehicles). Even in dimming
mode, the mirror surface turns bright when:
• the interior light is switched on
• reverse gear is engaged .
& WARNING
Broken glass of automatic dimming mirror can cause electrolyte
fluid leakage . Electrolyte fluid can irritate skin, eyes, and respira­
tory system.
• Repeated or prolonged exposure to electrolyte can cause irrita­
tion to the respiratory system, especially among people with
asthma or other respiratory conditions . Get fresh air immediately
by leaving the vehicle or, if that is not possible, open windows and
doors all the way.
• If electrolyte gets into the eyes, flush them thoroughly with
large amounts of clean water for at least 15 minutes; medical
attention is recommended.
• If electrolyte contacts skin, flush affected area with clean water
for at least 15 minutes and then wash affected area with soap and ._

T he condition of the battery is checked in the framework of the
inspection . We recommend rep lacing bat teries that are older than 5
years .
Disconnecting the battery
Some vehic le functions (power window regu lators, for example) are
lost if the battery terminals are disconnected . These functions have
to be relearned after the battery terminals are connected again. To
prevent this, the battery should only be disconnected from the
veh icle electr ical system if absolutely necessary.
V ehicle with 4 -cylind er engin e
The battery is located in the engine compartment~ page 236,
fig. 177 and is nearly maintenance -free.

known as a. gel battery* . When this battery is replaced, it must be
replaced wi th a or iginal bat tery o f th e same type.
Vehicles not dri ven for long periods and short-distance
operation
The battery can a lso become discharged with the vehicle stationary
by id ling current consumers .
Valid for vehicles with 4 -cylinder
engine :
When the vehic le is stationary (planned event) during the
cold time of the year, you sh ould remove the battery an d store it in
a nonfreezing area. This way you prevent that the battery "freezes"
and thereby is destroyed . During the
warmer time of the year it is
suff icient to disconnect the negative terminal from the battery .
Occasiona lly charge even a disconnected battery .
Valid for veh icles
with 6 -cylinder engine:
All wor k on the ba ttery should be per formed
by an authorized dealership.
Winter op eration
During the winter months, battery capacity tends to decrease as
temperatures drop. This is because more power is a lso consumed
while starting, and the headlights, rear window defogger, etc., are
use d more often .
Avoid unnecessary power consumption, particularly in city traffic or
wh en trave ling on ly shor t distances . Let you r au thor ize d Audi dea ler
check the capacity of the vehicle battery before winter sets in
~ page 240 . A well charged battery will not on ly prevent sta rting
problems when the weather is cold, but wi ll a lso last longer .
Replacing battery
The new battery must have the same capacity , vo ltage (12 volts),
a m perage, con struction and plug sea ling, as t he origina l battery.
Specifications are listed on the battery housing. Batteries specially
developed by Audi fulfill the maintenance, output, and safety
requirements.
When installing the battery , make sure the ignition and all electrical
co nsumers are switche d off ~
