36
So - All-weather lights*. The headlights automat-
ically adjust so that there will be less glare, for
example when the road surface is wet.
Q# - Rear fog lights*
Automatic dynamic headlight range control
system*
Your vehicle is equipped with a headlight range
control system so that there is less glare for on-
coming traffic if the vehicle load changes. The
headlight range also adjusts automatically when
braking and accelerating.
Light functions
The following light functions are available de-
pending on vehicle equipment and only function
when the light switch is in the AUTO position.
Static cornering light* (vehicles with LED head-
lights) - the cornering light switches on automat-
ically when the steering wheel is turned at a cer-
tain angle at speeds up to approximately 44 mph
(70 km/h) and when the turn signal is activated
at speeds up to approximately 25 mph
(40 km/h). The area to the side of the vehicle is
illuminated better when turning.
Highway light function* (vehicles with LED head-
lights) - This function adapts the lighting for
highway driving based on vehicle speed.
Speed dependent light distribution* (vehicles
with LED headlights) - The speed dependent light
distribution adapts the light in towns and on
highways or expressways. Intersections can also
be illuminated on vehicles with a navigation sys-
tem*.
ZA WARNING
— Automatic headlights* are only intended to
assist the driver. The driver is still responsi-
ble for controlling the headlights and may
need to switch them on and off manually
depending on light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams under these weather conditions and
when driving in the dark ZO. >

Lights and Vision


—To reduce glare for traffic behind your vehi-
cle, the rear fog lights* should only be
turned on in accordance with the legal regu-
lations in the country where you are operat-
ing the vehicle.
— If the battery has been discharging for a
while, the parking light may switch off auto-
matically. Always make sure your vehicle is
parked and adequately illuminated accord-
ing to the legal regulations in the country
where you are operating the vehicle. Avoid
using the parking lights for several hours.
G) Tips
— When using lighting equipment, the driver
is responsible for adhering to any local ap-
plicable regulations while driving and when
parking the vehicle.
— The light sensor for the automatic head-
lights* is in the rearview mirror mount. Do
not place any stickers in this area on the
windshield.
— Some exterior lighting functions can be ad-
justed > page 37.
— In some markets, the tail lights will switch
on when the daytime running lights switch
on.

—In cool or damp weather, the inside of the
headlights, turn signals, and tail lights can
fog over due to the temperature difference
between the inside and outside. They will
clear shortly after switching them on. This
does not affect the service life of the light-
ing.

if the mirrors fold in automatically when you lock
the vehicle > page 23.
Front passenger's exterior mirror tilt
function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
The mirror surfaces tilt slightly when reverse
gear is selected to provide a better view, for ex-
ample of the edge of the curb.
You can adjust the mirror surface by turning the
knob in the desired direction. When you move
out of reverse and into another gear, the new
mirror position is stored and assigned to the key
you are using.
The mirror goes back into its original position
once you drive forward faster than 9 mph
(15 km/h) or turn the ignition off.

Z\ WARNING
Curved mirror surfaces (convex) enlarge the
field of vision. However, they make objects in
the mirror appear smaller and farther away.
When using these mirrors to estimate your
distance to vehicles behind you when chang-
ing lanes, you could estimate incorrectly,
which increases the risk of an accident.

@) Note
If the mirror housing was moved by force (for
example, by running into an object when ma-
neuvering the vehicle), the mirror must be
folded all the way in using the power folding
function. The mirror housing must not be
moved back into place by hand because this
could impair the function of the mirror mech-
anism.
@ Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.

Automatic dimming rearview mirror*
> The interior and exterior mirrors* dim auto-
matically when light shines on them, for exam-
ple from headlights on a vehicle behind you.

Z\ WARNING
Electrolyte fluid can leak from automatic dim-
ming mirrors if the glass is broken. Electrolyte
fluid can irritate skin, eyes and airways.
— 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
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.
() Note
If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid
damages plastic surfaces. Clean this liquid as
quickly as possible, for example with a wet
sponge.

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* is set (switch @) to the
right), the earlier the windshield wipers react to
moisture on the windshield. You can deactivate
the rain sensor mode®* in the Infotainment sys-
tem, which switches the intermittent mode on.

this function off by moving the lever to position
© within ten seconds of the afterwipe. The after-
wipe function is reactivated the next time you
switch the ignition on.
If you hold the lever in position ) for longer
than half a second, the edge wiping feature will
be activated. This moves the wiper closer to the
edge of the windshield and performs an after-
wipe to clean the residue that results from the
wiping process from the edge of the windshield.
The function is available when driving at speeds
up to 75 mph (120 km/h).
The headlight washer system” only functions
when the lights are switched on. The headlights
are automatically cleaned the first time and ev-
ery fifth time the lever is moved to position ©).

ZX WARNING

the driver. The driver may still be responsi-
ble for manually switching the wipers on
based on visibility conditions.
