If dirt cannot be remove, clean the parts as follows:
●Use a soft cloth dampened with an approximately 5% solution of neutral
detergent and water to clean the dirt off.

● To remove oily deposits, use alcohol wet wipes or a similar product.
■ Notes for a smart key system
If the door handle becomes wet while the electronic key is within the effective
range, the door may lock and unlock repeatedly. In this case, follow the fol-
lowing correction procedures to wash the vehicle:
• Place the electronic key in a location 6 ft. (2 m) or more awa y from the vehi-
cle. (Take care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart key sys- tem. ( P. 116)
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.
