■

Condensation build-up on the inside of the lens

Temporary condensation build-up on the inside of the lens does not indicate a
malfunction. Contact your Toyota dealer for more information in the following
situations:

●

Large drops of water have built up on the inside of the lens.

●

Water has built up inside the lens.

WARNING

■

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.

■

To prevent damage or fire 

●

Make sure bulbs are fully seated and locked. 

●

Check the wattage of the bulb before installing to prevent heat damage.

Using an emergency hammer

*

 for emergency escape

The front side windows and rear side windows, as well as the rear window
can be shattered with an emergency hammer

*

 used for emergency escape.

inated glass.

*

: Contact  your  Toyota  dealer  or  aftermarket  accessory  manufacturer  for

further information about an emergency hammer.

■

Escaping the vehicle from the window

There are cases where escaping the vehicle from the window is not possi-
ble due to seating position, passenger body type, etc.
When  using  an  emergency  hammer,  consider  your  seat  location  and  the
size  of  the  window  opening  to  ensure  that  the  opening  is  accessible  and
large enough to escape.
