Maintenance and care
■LED light bulbs
The lights other th an the front turn
signal lights/parking lights (vehicles
without side turn sig nal lights), front
side marker lights (bulb type), rear
turn signal lights, rear side marker
lights (bulb type) and back-up lights
consist of a number of LEDs. If any
of the LEDs burn out, take your
vehicle to your Toyota dealer to
have the light replaced.
■Condensation build-up on the
inside of the lens
In certain situatio ns, such as when
driving in the rain or when washing
the vehicle, condensation may form
on the inner side of the headlight
lens and other li ghts. As each light
has a ventilation hole, moist air may
enter. If the ambient temperature is
low, condensation may form tempo-
rarily, but it will di ssipate as the
inside of the light i s warmed up. As
the condensation is due to a phe-
nomenon similar to windows fogging
in the rain, it doe s not indicate a
malfunction.
Contact your Toyota dealer for more
information in the following situa-
tions:
●Large drops of water have built up
on the inside of the lens.
●Water has built up inside the
headlight.
