Motion detector
G
WARNING
The motion detector sends the invisible
infrared 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 laserb eam
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 movemen tin
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 detecto rwithin
four seconds if:
R the rear interior light switch (Y page 95) 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
vehicles with automatic transmission and
the brake pedal is not being depressed and
R the vehicle has not been locked fro mthe
outside using the key
The motion detector switches off
automatically 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
contacts. There is a risk of fatal injury.
Never touch the parts or the electrical
contacts of the Xenon bulb. Always have work
on the Xenon bulbs carried out at a qualified
specialist 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 startingt he engine.
The bulbs and lamps are an essential
componentofv ehicle safety. You must

The auxiliary heating works independently of
the engine and supplements the climate
control system in the vehicle. The auxiliary
heating heats the air in the vehicle interior to
the temperature set.
If your vehicle is equipped with a hot-water
auxiliary heater, the auxiliary heating also
keeps the coolant warm. This way, the load
on the engine is minimized and fuel is saved.
