Maintenance and care
VENZA_OM_OM73030U_(U) CAUTION■ Replacing light bulbs
● Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
● Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
● Vehicles with discharge headlights:
While the headlights are turned on, and
for a short time after they have been
turned off, metal components at the
rear of the headlight assembly will be
extremely hot. To prevent burns, do not
touch these metal components until you
are certain they have cooled down.Metal

The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressu re will turn off the
warning light (after a few minutes).■
When a tire is replaced with a spare tire
The compact spare tire is not equipped with the tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire is replaced with the spare tire.

inflation pressure. The ti re pressure warn ing light will turn off after a few
minutes.
