General
Bulbs and lights
Lights and bulbs are an important aspect of driv‐
ing safety.
Some equipment versions have light-emitting di‐
odes behind a cover as a light source. These
light-emitting diodes are similar to conventional
lasers and are classified by legislation as Class 1
light-emitting diodes.
WARNING
Intense brightness can irritate or harm the ret‐
ina of the eye. There is a risk of injury. Do not
look directly into the headlights or other light
sources. Do not remove covers from LEDs.
In the case of a defect, the manufacturer of the
vehicle recommends having respective work car‐
ried out by a Service Partner of the manufacturer
or another qualified Service Partner or a special‐
ist workshop.
