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 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

■ 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.
■ Precaution regarding the rear bumper with Blind Spot Monitor (if
equipped)
If the paint of the rear bumper is chipped or scratched, the system may mal-
function. If this occurs, consult any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
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

ries and cause damage to the wiper
