and could cause permanent injuries to the
eyes.
— Dangerous exposure to laser beams may oc-
cur if the covers are removed or if the head-
lamp module housing is opened.

G) Tips
— The headlight contains a class 4 laser. The
technical design converts the laser beam so
that there is no danger when it is used for
its intended purpose.
—The laser beam emission from the head-
lamp has been classified in accordance with
IEC 60825-1:2007.
— The possible emission is below the thresh-
old for laser class 2.
—
Maximum laser beam output: 5W (continu-
ous emission), wavelength range A= 400 nm
- 700 nm.
— The headlamp light functions are rated in
accordance with IEC 62471-5:2015.
— The beam emitted from the headlamp was
classified as risk group 2.

=> page 42.
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.
The mirror moves from the reversing position

ZA 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.
G) Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.
Dimming the mirrors
> The interior and exterior mirrors dim automati-
cally when light shines on them, for example
from headlights on a vehicle behind you.


ZX WARNING
— If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid >
