Useful information
This Operator's Manual describes all models
as well as standard and optional equipment
of your vehicle that were available at the time
of going to print. Country-specific variations
are possible. Note that your vehicle may not
be equipped with all of the described
functions. This also applies to systems and
functions relevant to safety.
Read the information on qualified specialist
workshops (Y page 26). Exterior lighting
Important safety notes
For reasons of safety, we recommend that
you drive with the lights switched on even
during the daytime. There may be differences
in operation due to legal requirements and
voluntary recommendations in some
countries. Lamp failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-
functioning vehicle lightin gputs the operating
safety of the vehicle at risk.
For this reason, check the condition and
function of your vehicle's lighting system and,
if necessary, that of the trailer before each
journey.
The bulb failure indicator monitors all of the
exterio rlighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails,
either the 0002(Ypage 34) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 201).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exceptio nofthe turn signal lamps. Light switch
