About replacing bulbs
Safe vehicle operation depends on proper
exterior lighting and signaling. It is
therefore essential that all bulbs and lamp
assemblies are in good working order at all
times.
Correct headlamp adjustment is extremely
important. Have headlamps checked and
readjusted at regular intervals and when a
bulb has been replaced. Contact an author-
ized electric drive smart center for head-
lamp adjustment. G
WARNING
Bulbs and bulb sockets can be very hot.
Allow the lamp to cool down before changing
a bulb. Otherwise you could be burned if you
touch them.
Keep bulbs out of the reach of children.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
R touch or move it when hot
R drop the bulb
R scratch the bulb
Wear eye and hand protection.
i If the headlamps or front fog lamps* are
fogged up on the inside as a result of
high humidity, driving the vehicle a
distance with the lights on should clear
up the fogging. Notes on bulb replacement:
R
Only use bulbs of the same type and with
the specified watt rating.
R Switch the lights off before replacing a
bulb to prevent short circuits.
R Always use a clean lint-free cloth when
handling bulbs.
R Your hands should be dry and free of oil
and grease.
R Avoid touching the glass of the bulb with
bare fingers.
R If the newly installed bulb does not come
on, contact an authorized electric drive
smart center.
R Have the bulbs for the front fog lamps*
and the LED daytime running lamps*
replaced at an authorized electric drive
smart center. Replacing bulbs
