Move the windshield wiper lever to the corre­
spond ing pos ition:
@ -Windshield wipers off
(D-Interval mode. To increase/decrease the wip­
er intervals, move the switch
@ to the left/right.
In vehicles with a rain sensor, the wipers turn on in the rain once the vehicle speed exceeds ap­
proximately 2 mph (4 km/h). The higher the sen­
sitivity of the rain sensor that is set (switch
@ to
the right), the earlier the w indshield w ipers react
to moisture on the windshield . You can deacti­
vate the rain sensor mode in the Infotainment
system, wh ich switches the intermittent mode
on. To do this, select :
I MENU I button> Vehicle>
left control button > Driver a ssistance > Rain
se nsor.
@ -Slow wiping
@ -Fast wiping
@-Single wipe. If you hold the lever in this posi­
tion longer, the wipers switch from slow wiping
to fast wiping.
Lights and Vision
®-Clean the windshield. To eliminate water
droplets, the windshield wipers perform one af­
terw ipe after several seconds while dr iv ing in
temperatures above 39 °F (4 °C). You can switch
this function off by moving the lever to position
@within 10 seconds of the afterwipe . The after ­
wipe function is react ivated the next time you
switch the ignition on .
Clean the headlights. The headlight washer sys­
tem operates only when the low beam headlights
are sw itched on . If you move the lever in position
®, the headlights will be cleaned in fixed inter­
vals.
Applies to: vehicles wi th rear window wiper
@ -Wipe the rear window. The rear wiper moves
about every 6 seconds .
The rear wiper automatically switches on when
the reverse gear is selected and the front wind­
sh ield wipers are on and running.
(j)-Clean the rear window . The number of wipes
depends on how long the lever is held in position
(j) .
A WARNING
-The rain sensor* is only intended to assist
the driver. The driver may still be responsi­
ble for manually switch ing the w ipers on
based on visibility conditions.
-The windsh ield may not be treated w ith wa­
ter-repelling windshield coating agents. Un­
favorable conditions, such as wetness, dark­
ness and when the sun is low, can cause in-
'
creased glare, which increases the r isk of an
accident. Wiper blade chatter is also possi­
ble.
-Properly functioning windshield wiper
b lades are required for a clear view and safe
driving¢ page 56, Replacing the front
wiper blades.
(D Note
- If there is frost, make sure the windshield
wiper blades are not frozen to the wind­
shield. Switching on the windshield wipers
when the blades are frozen to the wind­
shield can damage the wiper blades .

Outside mirrors
If yo u cannot see the traffic behind the tra iler
with the standard exterior mirrors, then you
must attach additiona l exterior mirrors . Adj ust
them so you have a sufficient visibility behind
you .
Exterior lighting
Follow the legal regulat ions regard ing the light­
ing equipment on your trailer . Contact an author ­
ized Audi dealer or authorized Audi Service Facili­
ty for more information.
Before starting to drive, check all lighti ng equip­
ment on the hitched trailer.
The headlight range contro l adjusts automatical­
l y to the light range of the headl ights.
Safety chains
Make sure the safety chains are correctly applied
when pull ing a trailer . The chains should hang
enough so that the trailer can dr ive around
curves. However, they must not touch the
g ro und .
(D Tips
-Use chocks whe n parking on incl ines if the
trailer is load ed.
- We recommend also hav ing the veh icle in­
spected between the inspect ion intervals if
you are towing a trailer frequently.
- Avo id driving with a trailer during the vehi­
cle break- in period .
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed limits. Follow the legal
regulations specific to the country.
As the speed increases, the driving stability of
the trai ler decreases. Therefore you should not
exceed the maximum legal speed limit when
u. there are unfavorable road, weather and/or wind 00
~ conditions . This especially applies when driving
~ downhill.
0 N > 00
Trailer towing
You m ust always reduce your speed as soon as
you notice even the slightest swinging motion of
the tra iler. Never try to "stra ighten out" the tra il­
er by acce lerating.
T he weight distribution is very poor if the vehicle
is empty and the trai ler is loaded . However if you
must drive under these circumstances, then dr ive
especially slowly .
Brakes
Brake in a timely manner. Downshift before driv ­
ing down hill so that t he engine can assist with
braking ~.&. .
When using a trailer w it h overrun brakes, first
brake gently then quickly. This reduces the r isk of
jerking while braking if the trailer wheels lock up .
Engine coolant temperature
Pay attention specifically to the coo lant tempera­
ture display when there are high outside temper­
a tur es, and when driving on long inclines
~page 11. Shift to a hig her gear in a timely man­
ner .
A WARNING
= -
Constant braking causes the brakes to over-
heat and substantially reduces braking per­
formance, increases braking distance or caus­
es complete failure of the brake system.

the battery housing can crack and battery electrolyte can leak out, which increases the
risk of a n explos ion and chemical burns .
