Maintenance and care
COROLLA_TMMMS_TMMC_U (OM02494U)■When using a car wash (vehicles with 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 that case, follow the fol-
lowing correction procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or more separate from the vehicle
while the vehicle is being washed. (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. 126)
■Aluminum wheels (if equipped)
●Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not use strong or harsh chemical clean-
ers.
Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers
Do not scrub with abrasive cleaners.
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.
■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.
