2012 AUDI Q7 wiper blades

64 Clear vis ion
General information
The winds hield wipers and the w indshield
washer system operate only with the ignition
on.
During a temporary stop , e.g . at a t raff ic sig­
na l, the set wipe speed is automatically re­
duced by one stage.
The winds hield washer no zzles a re heated at
l ow temperatures when the ignition is on .
Removing w ate r droplet s
About 5 seconds after the wash cycle is com­
plete, the wiper system performs a single au ­
tomatic wipe cycle to remove any water drop­
l ets that remain on the windshield whi le dr iv ­
ing.
If you would like to deactivate this delayed
wipe cycle wh ile driving, you have to pull the
l eve r to pos ition ® again within 10 seconds
after this wipe cy cle.
Water droplet removal is reactivated after the
ignit ion is switched off and then on again .
Winter position
To speed up de -icing of the w indshield w ipers,
t hey move to the winter posi tion when the ig­
n ition is switched off and at an outside tem­
perature below 39
°F (4 °(). In this posit ion ,
the w indshield wipers are in an area on the
g lass w hich is reached by the a ir vents below
the glass. It is also easier to remove snow and
ice from the wi ndshield wipers in this posi­
tion .
The wipe rs leave the w inte r position, when
the ign ition is swi tc h ed on, if the winds hield
wiper lever is operated or the active rain sen­
sor reacts to moistu re.
Rain sensor
The rain senso r operates on ly in the inte rva l
wiper position . When it sta rts to ra in , the in­
terval wipe r mode is activated automati ca lly.
If the windshie ld w iper lever is in the inte rval
wipe posit ion w ith the ign ition switched off, the ra
in sensor is not activated until ve hicle
sp eed is above 4 mph (6 km/h).
T o red uce the sensi tivi ty of the rain senso r,
the switch @ mus t be moved down . T o in­
crease the sensitivity of the rain sensor, the
switch must be moved up.
T he higher the sensit iv ity se tt ing , the sooner
the windshie ld wipers react to moist ure on
the windshie ld . I nc reased sensitivity is sig­
naled by the windshie ld wipers making a sin­
gle pass over the windshield.
T he rain sensor w iper intervals depend on the
sensitivity setting as well as vehicle speed.
D uring brief stops, wiper motio n will adj ust in
relat ion to the amount o f rain on the w ind­
shield .
A WARNING
-W iper blades are crucial for safe driving!
O nl y when they are i n good co ndit io n are
they able to clear the windows prope rly
to p rov ide uncompromised vis ib ility.
Wo rn o r damaged wipe r blades are a
safety ha zard
~ page 66, Replacing
windshield wiper blades!
- T he rain sen so r is only designed to assist
a nd suppor t the driver.
It rem ains enti re­
ly the d river 's responsibility to monitor
outside weathe r conditions and to man­
ually activate the wipe rs as soon as rain
or driz zle reduces visibility through the
windshie ld.
(D Note
In freezing or near freezing conditions:
- Always check that the w iper b lades are
not frozen to the g lass before you turn
the wipe rs on . Loosen a wiper blade
wh ich is frozen in place before operating
the wipers to prevent damage to the
w iper blade or the wiper motor.
- Do not use the w ipers to clear a frosted
w indow. Us ing the wipers as a conven­
ient ice scrape r will destroy the wiper
blades .

-Prior to using a car wash, the windshield
wiper system must be switched
off (lever
i n position 0) . This helps to prevent unin ­
tentiona l switching on and damage to
the windshie ld w iper system .
@ Tips
-The windshield wipers are switched off
when the ignition is turned off. Activate
the w indshield w ipers after the ignit ion
i s switched back on by moving the wind­
sh ield wiper lever to any pos ition.
- Worn or dirty windshield wiper blades
cause smearing which can affect the op­
eration of the rain sensor . Check the con­
dit ion of yo ur windshield wipe r blades
regularly.
- The rain sensor is part of the interval
wiping system. Turning
off the ignition
will a lso deact ivate the rain sensor. To re­
activate the sensor, sw itch
off the inter­
va l w iping function, then switch it back
on again.
- Make sure the washer fluid reservoir in
the engine compartment is topped
off
before going on a long trip . Look up
c:;, page 2 73 for checking and fi lling the
washer container.
