Changing bulbs. Bi-Xenon AFS headlights Types of bulbs
Changing bulbs requires a certain degree of practical skill
You can change the following bulb for the exterior lights yourself:
● Bulb for headlights: Indicator light 12V/21W (PY21W)
The following bulbs should only be changed by a specialised workshop:
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

272If and when
● Main headlight lamps: Xenon ⇒ 
lights.
● Sources of the DRL (daylight) light unit and position.
WARNING
● Take particular care when working on components in the engine com-
partment if the engine is warm - risk of burns!
● Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.
● The high voltage element of gas discharge bulbs* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.
● When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.
CAUTION
● Remove the ignition key before working on the electric system. If not, a
short circuit could occur.
● Switch off the lights or parking lights before you change a bulb.
For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the prop-
er manner.
Note
● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted.
● Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning properly. This is not only in the inter-
est of your own safety, but also in that of all other road users. ●
Before changing a bulb, make sure you have the correct new bulb.
● Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will va-
porise as a result of the heat generated by the bulb, be deposited on the
reflector and impair its surface. 
Removing the air duct
The air duct has to be removed to gain access to the bulbs
for the right-side headlight.
