When using a car wash (veh icles with a smart key system)
If the door handle becomes wet while the electronic key is within the ef\
fective
range, the door may lock and unlock repeatedly. In that case, follow the fol-
lowing correction procedures to wash the vehicle:
l 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.)
l Set the electronic key to battery-saving mode to disable the smart key sys-
tem. ( P. 118)
n Aluminum wheels (if equipped)
lRemove 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.
l Do not use detergent on the wheels when they are hot, for example after
driving for long distance in the hot weather.
l Wash detergent from the wheels immediately after use.
n Bumpers
Do not scrub with abrasive cleaners.
CAUTION
nWhen 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.
n 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.

n Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
lIf recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
l Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
n After recharging/reconnecting the ba ttery (vehicles with a smart key sys-
tem)
l Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the battery. If this happens, use the wireless
remote control or the mechanical key to lock/unlock the doors.
l Start the engine with the engine switch in ACCESSORY mode. The engine
may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
l The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before the battery was disconnected. Make sure to turn off the engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
