12.8 Replacing bulbs, external
Types of bulbs Different types of bulbs are used in the vehicle. Below, we have described how
to change the different types of bulbs.
X Bulbs and light fittings can be extremely hot. Therefore, allow lights to
cool down before changing bulbs.
X Store bulbs in a safe place inaccessible to children.
X Do not use any bulb that has been dropped or which shows scratches in
its glass. The bulb might burst.
Z A new bulb should not be touched with the fingers. Use a cloth when
installing the new bulb.
Z Use only bulbs of the same type and with the correct wattage (see
section 12.8.4 "Types of bulbs for exterior lighting").
Z If LEDs in lights are defect, contact an authorised dealer or service centre.
