Automatic car washes
●Fold the mirrors before washing the vehicle. Start washing from the fron\
t of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle surface and
harm your vehicle's paint.
● Rear spoiler may not be washable in some automatic car washes. There
may also be an increased risk of damage to vehicle.
■ High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of
the windows.
● Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■ Note for a smart key system (if equipped)
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:
●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. 120)
■ Aluminum wheels
●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 and side moldings

■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
●If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.
■ After recharging/reconnecting the ba ttery (vehicles with a smart key sys-
tem)
● The engine may not start. Follow the procedure below to initialize the sys-
tem.
Shift the shift lever to P.
Open and close any of the doors.
Restart the engine.
● 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.
● 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.
● 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 disconnecting the battery. Take extra care when connecting the bat-
tery if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts at all methods above,
contact your Toyota dealer.
