7-1. Maintenance and care
●Working from top to bottom, liber ally apply water to the vehicle
body, wheel wells and underside of the vehicle to remove any dirt
and dust.
● Wash the vehicle body using a sponge or soft cloth, such as a
chamois.
● For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
● Wipe away any water.
● Wax the vehicle when the wate rproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle
body is cool.
■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.
● In certain automatic car washes, the rear spoiler may interfere with machine
operation. This may prevent the vehicle from being cleaned properly or
result in damage to the rear spoiler.
■ 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.
■ When using a car wash (vehicles 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:
●Place the electronic key in a location 6 ft. (2 m) or more away 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. 141)

When disconnecting the 12- volt battery terminals
Always disconnect the negative (-) terminal first.
■ After recharging/reconnecting the 12-vo lt battery (vehicles with a smart
key system)
● Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the 12-volt battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.
● Start the hybrid system with the “POWER” switch in ACCESSORY mode.
The hybrid system may not start with the “POWER” switch turned off. How-
ever, the hybrid system will operat e normally from the second attempt.
● The “POWER” switch mode is recorded by the vehicle. If the 12-volt battery
is reconnected, the vehicle will return the “POWER” switch mode to the sta-
tus it was in before the 12-volt battery was disconnected. Make sure to turn
off the power before disconnect the 12-volt battery. Take extra care when
connecting the 12-volt battery if the “POWER” switch mode prior to dis-
charge is unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.

● Do not smoke or light a match near the 12-volt battery.
● Avoid contact with eyes, skin and clothes.
● Never inhale or swallow electrolyte.
● Wear protective safety glasses when working near the 12-volt battery.
● Keep children away from the 12-volt battery.
