road wheels. As a result, the vehicle han-
dling characteristics change when driving
with a spare wheel with collapsible tire
mounted.

400 Practical hintsReplacing bulbsSafe vehicle operation depends on proper
exterior lighting and signaling. It is there-
fore essential that all bulbs and lamp as-
semblies 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. See an authorized
Mercedes-Benz Center for headlamp ad-
justment.
iIf the headlamps are fogged up on the
inside as a result of high humidity,
driving the vehicle a short distance with
the lights on should clear up the
fogging.
iBackup bulbs will be brought into use
when lamps malfunction. Observe the
messages in the multifunction display
(page 382).
