Motion detector
G
WARNING
The motion detector sends the invisible infra-
red radiation emitted by LEDs (light emitting
diodes).
These LEDs are classified as class 1M lasers
and can damage the retina if you:
R look directly into the unfiltered laser beam
of the motion detector for an extended
period
R look directly into the laser beam of the
motion detector using optical instruments,
e.g. eyeglasses or a magnifying glass.
There is a risk of injury.
Never look directly into the motion detector.
The cargo compartment lighting is also
switched on by the motion detector in the
cargo compartment of Cargo Vans equipped
with this feature.
If the motion detector detects a movement in
the cargo compartment when the vehicle is
stationary, the cargo compartment lighting
switches on for approximately two minutes.
The cargo compartment lighting can be
switched on by the motion detector within
four seconds if:
R the rear interior light switch (Y page 99) is
set to automatic control.
R the vehicle is stationary, the parking brake
is applied and the brake pedal is not being
depressed
Or
R the selector lever is in position Pon vehi-
cles with automatic transmission and the
brake pedal is not being depressed and
R the vehicle has not been locked from the
outside using the key
The motion detector switches off automati-
cally if no change is detected in the vehicle
for several hours, e.g. if a door is opened, if
the ignition key is turned, etc. This prevents
the battery from becoming discharged. Changing bulbs
Important safety notes
G
DANGER
Xenon bulbs carry a high voltage. You can get
an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop. G
WARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
! Make sure the bulbs are always securely
installed.
If your vehicle is equipped with Bi-Xenon
bulbs, you can recognize this by the following:
the cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the low-beam headlamps must be
switched on before starting the engine.
The bulbs and lamps are an essential compo-
nent of vehicle safety. You must therefore
make sure that these function correctly at all
times. Have the headlamp setting checked
regularly.
R Always switch off the vehicle's lighting sys-
tem before changing a bulb.
This will prevent a short circuit.
R Do not touch the glass tube of new bulbs
with your bare hands. Always use a clean,
lint-free cloth or only touch the base of the
bulb when installing.
Even minor contamination can burn into
the glass surface and reduce the service life
of the bulbs. 100
