PRIUS +_OM_OM47D30E_(EE)
WARNING
■When washing the vehicle 
Do not apply water to the inside of the engine compartment. Doing so may 
cause the electrical components etc. to catch fire. 
■ When cleaning the windshield (vehicles with rain-sensing windshield 
wipers) 
● When the upper part of the windshield where the raindrop sensor is 
located is touched by hand 
● When a wet rag or similar is held close to the raindrop sensor 
● If something bumps against the windshield 
● If you directly touch the raindrop sensor body or if something bumps into 
the raindrop sensor 
■ Precautions regarding the exhaust pipe 
Exhaust gasses cause the exhaust pipe to become quite hot. 
When washing the vehicle, be careful not to touch the pipe until it has 
cooled sufficiently, as touching a hot exhaust pipe can cause burns.
Set the wiper switch to off.
If the wiper switch is in “AUTO”, the wip- 
ers may operate unexpectedly in the fol- 
lowing situations, and may result in
hands being caught or other serious inju- 
ries and cause damage to the wiper 
blades.

NOTICE
■When using an automatic car wash (vehicles with rain-sensing wind- 
shield wipers) 
Set the wiper switch to the off position. 
If the wiper switch is in “AUTO”, the wipers may operate and the wiper 
blades may be damaged. 
■ To prevent damage to the panoramic roof (if equipped) 
Observe the following precautions. Otherwise, the surface of the panoramic 
roof may be damaged, or the deterioration of the coating may be acceler- 
ated. 
● Before washing the vehicle, remove any dust, sand or other foreign matter 
using water. 
● Do not use harsh brushes, scrubbing brushes or sharp objects to wash the 
roof. Use only soft cloths or sponges. 
● Use a mild soap when removing dirt, and avoid the use of oil-based prod- 
ucts (such as glass coating or car wax), alcohol-based products (such as 
glass cleaner), or abrasive cleansers.
After cleaning, wash away any remaining soap with water. 
● If there is iron oxide on the vehicle, wash it away with water while wiping 
gently without scrubbing. 
● Do not attach suction cups or sticky objects, such as stickers. 
Promptly remove the information label attached to the panoramic roof after 
confirming the content. 
● If snow has accumulated on the roof, remove it while being careful to avoid 
scratching the roof. 
If there is frost or ice on the roof , avoid the use of scrapers or de-icer.
