times. Replacement bulbs are available from a suitably qualified workshop. In some countries it is a legal requirement
to have these spare bulbs in the vehicle.
It may be illegal to drive with a defective bulb in the exterior lighting.
Additional bulb specification
Some bulbs in headlights or in tail light clusters might have factory specifications that are different to standard bulbs.
The designation is inscribed on the bulb, either on the glass part or on the base.
WARNING
Accidents can occur if roads are not sufficiently illuminated and other road users have difficulty seeing the vehicle,
or cannot see it at all.
WARNING
Changing the bulb incorrectly can cause accidents and serious injuries.
● Always read and observe the warnings before carrying out work in the engine compartment (→ In the engine
compartment). The engine compartment of any motor vehicle is a dangerous area. Serious injuries can be
sustained here.
● Please note that halogen bulbs are pressurised and can burst when bulbs are changed.
● Change the defective bulb only once it has cooled down completely.
● Never change a bulb unless you know exactly how to carry this out. If you are uncertain of what to do, have the
work carried out by a suitably qualified workshop.
● Do not touch the glass part of the bulb with unprotected fingers. When the light is switched on, heat will cause
fingerprints to evaporate on the bulb, which in turn will cause the reflector to dim.
● There are sharp-edged parts on the headlight housing and on the tail light cluster housing. Protect your hands
when changing bulbs.
NOTICE
Damage to the electrical system can be caused by water entering the system if the rubber cover or plastic caps on
the headlight housing are not properly mounted after a bulb has been changed.
