Dimming the mirrors
Fig. 43 Automatic dimming rearview mirror
Manual dimming rea rview mirror
• Pull the lever on the bottom of the mirror back.
Automatic dimming rearview mirror*
• Press the button (D ~ fig. 43. The indicator
light @turns on . Interior and exterior mirrors*
will dim when there is incoming light (such as
headlights from the rear) .
A WARNING
Electrolyte fluid can leak from automatic dim­
m ing mirrors if the glass is broken. Electro­
lyte fluid can irritate skin, eyes and airways.
- Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the a ir ­
ways, especially in people with asthma or
other resp irato ry conditions. Take deep
breaths immed iate ly after leaving the vehi­
cle or, if this is not possible, open all of the
doors and windows as wide as possible .
-If electrolyte f lu id ente rs the eyes, flush
them thoroughly with a large amount of
clean water for at least 15 minutes and then
seek medical attention.
- If electrolyte f luid comes into contact with
the skin, flush the affected area with clean
water for at least 15 minutes and then clean
with soap and water and seek medical at­
tention. Clean affected clothing and shoes
thoroughly before wearing again .
- If the fluid was swallowed and the person is conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by med ical pro-
42
fessionals . Seek medical attention immedi­
ately .
(D Note
If the glass on an automatic dimming mirror
breaks, electro lyte can leak out . This liquid
damages plastic surfaces. Remove the liquid
as quickly as possible, for example us ing a
wet sponge.
(D Tips
- If the light reaching the rearview mirror is
obstructed, the automatic dimming mirror
will not function correctly,
- The automatic dimming mirrors do not dim
when the interior lighting is turned on or
the reverse gear is selected.

sponding position:
@ -Windshield wipe rs off
(D -Interval mode . T o increase/decrease the w ip­
er intervals, move the sw itch

I n vehicles with a ra in senso r*, the wipe rs turn o n
in the ra in once the vehicle speed exceeds ap ­
p roximate ly 2 mph (4 km/h). The h igher the sen ­
sitivity of the rain sensor* is set (switch @to the
right), the earlier the winds hield wipers react to
mo isture on the windshield. You can deact ivate
the ra in sensor mode* in the Infotainment sys­
tem, which switches the intermittent mode on.

© -Sing le w ipe. If yo u hold t he leve r in th is posi ­
tion longer, the wipers sw itch from s low w iping
to fast wiping.
® -Clea n the wi ndshield . To e liminate water
d roplets, the windsh ield wipers pe rform one af ­
terwipe after several seconds wh ile driving in
temperatures above 39 ° F (4 °C). You can switc h
this function off by moving the lever to position
@ within 10 seconds of the afterwipe. The after­
wipe function is reactivated the next t ime you
switch the ignition on.
C lean the headlights*. The headlight washer sys­
tem* only functions when the lights are switched
on. The headlights are automat ically cleaned the
f irst time and every fifth t ime the lever is moved

A WARNING
- T he ra in sensor* is o nly intended to ass ist

ble fo r manua lly swit ching the wi pe rs on

- T he w indshie ld ma y not be treated with wa ­
te r-repell ing winds hield coa ting age nts. Un­
f avor ab le cond itions, s uch a s wetness, dar k­
ness, and when the s un is low, can cause in ­
creased g lare, which increases the risk of an

accident. Wiper b lade chatter is also possi ­
b le.
- Properly functioning windshield wiper
b lades are required for a clear v iew and safe
driving¢ page 44, Replacing windshield
wiper blades.
@ Note
- If there is frost, make sure the windshield
w iper blades are not frozen to the wind­
shield. Switching on the w indshield w ipers
when the blades are frozen to the wind­ shield can damage the w iper blades.
- The windshie ld w iper system must be
sw itched off (lever in posit io n 0) before us­
ing a car wash. This prevents the w ipers
from switc hing on un intent io nally and caus­
ing damage to the winds hield wiper system.
(D Tips
- T he windsh ie ld w ipers sw itch off when the
ign ition is switched off. You can activate the
w indshield w ipe rs after the ignition is
sw itched back on by mov ing the w indshield
w iper lever to a ny posi tion.
- Wor n or d irty w indshie ld w iper blades res ult
in st reaking. This can affect t he rain senso r*
function. Chec k your w indshie ld w iper
blades reg ularly.
- Th e washer fluid no zzles in the winds hield
washe r system are heated* at low tempera ­
t ur es when the ignition is on .
- Whe n stopping tempo rar ily, such as at a
traffic lig ht, the speed of the windshield
wipers automatica lly reduces by one level.
Cleaning windshield wiper blades
Clean the wiper b lades when you see w iper
streaks. C lean the wiper blades with a soft towel
and glass cleaner .
.,. Place the windshie ld wiper arms in the service
position

Intelligent Technology
Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently
in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Wet conditions or road salt
I n certain situations, for example after dr iving
through water, in heavy ra in or after washing
your car, the braking effect may be reduced due
to moisture or ice on the brake rotors and brake
pads . The brakes must be "dried" first with a few
careful brake applications.
At higher speeds and with the windshie ld wipers
turned on, the brake pads press against the brake
rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and
pads¢ &.
Brake system malfunction
If you notice that the brake pedal travel has sud ­
denly increased, then a brake circuit in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Aud i dea ler or authorized
Aud i Serv ice Facility immediately to have the
88
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
t h e brake system may occur . The brake fluid leve l
is electronically monitored .
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
& WARNING
- New brake pads do not achieve their full
braking effect during the first 250 mi
-
(400 km). They must be "broken in" first .
However, you can compensate for the
slightly reduced braking force by pressing
firm ly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- On ly app ly the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users . This increases the
r is k of an accident.
- On steep slopes, reduce the speed and se­
lect a lower gea r or lower selector leve r po­
sition. Drive as lit tl e as possible while press­
ing the brake pedal and avo id putting yo ur
left foot on the brake pedal while driv ing .
This could ca use the brakes to overheat and
impair the efficiency of th e brakes.
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces­
sarily.
- Certain weather and operating conditions such as driving through water, dr iv in g in
heavy rain or driv ing after wash ing your ve­
h icle can impair the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums. Check
these compon ents by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up.

Fuses and bulbs
The power seats* are protected via circuit break­
ers
that automatically switch on after a few sec­
onds after the overload has been reduced.
