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 autho
rized smart center for headlamp adjustment.

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.
