Applies to: vehicles with high beam assistant

The high beam assistant automatically turns the
high beams on or off depending on the surround-
ing conditions.
A camera on the rearview mirror mount can de-
tect light sources from other road users. The high
beams switch on or off automatically depending
on the position of vehicles driving ahead and on-
coming vehicles, the vehicle speed as well as oth-
er environmental factors and traffic conditions.

Lights and Vision


— High beam assistant is only intended to as-
sist the driver. The driver is still responsible
for controlling the headlights and may need
to switch them on and off manually depend-
ing on light and visibility conditions.
— High beams can cause glare for other driv-
ers, which increases the risk of an accident.
For this reason, only use the high beams or
the headlight flasher when they will not cre-
ate glare for other drivers.
@ Tips
Certain settings are automatically stored and

0 - Deactivates all adjustment functions.
Q/ ®- Selects the left or right exterior mirror.
To adjust the mirror glass in a mirror, press the
knob in the desired direction.
GR - Heats the mirror glass depending on the out-
side temperature.
S) - Folds the exterior mirrors*. To fold the mir-
rors out, turn the knob to one of the other posi-
tions. In the MMI, you can select if the mirrors
fold in automatically when you lock the vehicle
> page 31.
Front passenger's exterior mirror tilt
function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
To help you see the curb when backing into a
parking space, the surface of the mirror will tilt
slightly when reverse gear is selected.
You can adjust the mirror surface by turning the
knob in the desired direction.
The mirror moves from the reversing position
back to the original position:
— When you switch the ignition off
— Once you drive forward at speeds faster than 9
mph (15 km/h)
— When the knob is no longer in the position for
the front passenger exterior mirror

Z\ WARNING
Curved mirror surfaces (for example convex)
enlarge the field of vision. However, they
make objects in the mirror appear smaller and
farther away. When using these mirrors to es-
timate your distance to vehicles behind you
when changing lanes, you could estimate in-
correctly, which increases the risk of an acci-
dent.

@) Note
— Applies to: vehicles with power folding exte-
rior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must use the pow-
er folding function to fold the mirror all the
way out. The mirrors will make a loud noise
when they latch into place. The mirror hous-
ing must not be moved back into place by
hand because this could impair the function
of the mirror mechanism.
— Applies to: vehicles without power folding
exterior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must move it back
in place by hand.
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Never fold power folding exterior mirrors*
by hand. Only fold them in and out using
the power controls.
@) Tips
—If the power adjusting function malfunc-
tions, the glass in both mirrors can be ad-
justed by pressing on the edge of it by hand.
— Certain settings are automatically stored
and assigned to the active user.
Dimming the mirrors
Manual dimming rearview mirror
> Pull the lever on the bottom of the mirror back.
Automatic dimming rearview mirror*
> The interior and exterior mirrors* dim automat-
ically when light shines on them, for example
from headlights on a vehicle behind you.

Z\ WARNING
— If the glass on an automatic dimming mir-
ror* breaks, electrolyte can leak out. This
liquid can irritate the skin, eyes and respira-
tory system. If there is contact with the flu-
id, flush immediately with plenty of water.
Consult a physician if necessary.
— Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the air-
ways, especially in people with asthma or
other respiratory conditions. Take deep >

Lights and Vision


breaths immediately after leaving the vehi-
cle or, if this is not possible, open all of the
doors and windows as wide as possible.
— If electrolyte fluid comes into contact with
the eyes, flush them thoroughly with plenty
of clean water for at least 15 minutes and
then seek medical attention.
— If electrolyte fluid 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
attention. 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 medical pro-
fessionals. Seek medical attention immedi-
ately.



If the glass on an automatic dimming mirror*
breaks, electrolyte can leak out. This liquid
damages plastic surfaces and paint. Clean
this liquid as quickly as possible, for example
with a wet sponge.


— 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 re-
verse gear is selected.

@ Rain sensor/intermittent mode. The wind-
shield wipers switch on once the vehicle speed
exceeds approximately 2 mph (4 km/h) and it is
raining. The higher the sensitivity of the rain sen-
sor that is set (switch © to the right), the earlier
the windshield wipers react to moisture on the
windshield. You can deactivate the rain sensor

by moving the lever to position ©) within ten sec-
onds of the afterwipe. The afterwipe function is
reactivated the next time you switch the ignition
on.

tem* operates only when the low beam head-
lights are on. If you move the lever into position
©, the headlights will be cleaned at fixed inter-
vals.
Applies to: vehicles with rear window wiper: @)
Wiping the rear window ]. The number of wipes
depends on the windshield wiper movement.
The rear wiper automatically switches on when
the reverse gear is selected and the front wind-
shield wipers are on and running.
Applies to: vehicles with rear window wiper:
Cleaning the rear window &. The number of
wipes depends on how long the lever is held in
position @).
This may also clean the rearview camera, depend-
ing on the vehicle equipment.

Z\ WARNING
—The rain sensor is only intended to assist the
driver. The driver may still be responsible for
manually switching the wipers on based on
visibility
conditions.
—The windshield must not be treated with
water-repelling windshield coating agents.
Under unfavorable conditions, such as wet-
ness, darkness, and when the sun is low,
these coatings can cause increased glare,
which increases the risk of an accident. They
can also cause wiper blade chatter.
— Properly functioning windshield wiper
blades are required for a clear view and safe
driving > page 56, Cleaning/changing wip-
er blades.
@) Note
— If there is frost, make sure the windshield
wiper blades are not frozen to the


55

Lights and Vision

windshield. Switching on the windshield
wipers when the blades are frozen to the
windshield can damage the wiper blades.
— Prior to using a car wash, the windshield
wiper system must be switched off (lever in
position @). This prevents the wipers from
switching on unintentionally and causing
damage to the windshield wiper system.
G) Tips
— The windshield wipers switch off when the
ignition is switched off. You can activate the
windshield wipers after the ignition is
switched on again by moving the windshield
wiper lever to any position. The single wipe
function (lever in position @) also functions
when the ignition is switched off.
— Worn or dirty windshield wiper blades result
in streaking. This can affect the rain sensor
function. Check your windshield wiper
blades regularly.
— The washer fluid nozzles for the windshield
washer system are heated when the ignition
is on if the outside temperature is low.
— When stopping temporarily, such as at a
traffic light, the speed of the windshield
wipers automatically reduces by one level.
— Certain settings are automatically stored
and assigned to the active user.
