When using a car wash
If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. Place the key in a posi-
tion 2 m (6 ft.) or more separate from the vehicle while the vehicle is being
washed. (Take care to ensure that the key is not stolen.)
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
cleaners.
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.
Front side windows water-repellent coating (if equipped)
The following precautions can extend the effectiveness of the water-
repellent coating.
• Remove any dirt etc. from the front side windows regularly.
• Do not allow dirt and dust to accumulate on the windows for a long
period. Clean the windows with a soft and damp cloth as soon as pos-
sible.
• Do not use wax or glass cleaners that contain abrasives when cleaning
the windows.
• Do not use any metallic objects to remove condensation build up.
When the water-repellent performance has become insufficient, the coat-
ing can be repaired. Contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.

Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautions before
recharging:
If recharging with the 12-volt 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
disconnecting the charger cables to the 12-volt battery.
After recharging/reconnecting the 12-volt battery
Unlocking the doors using the smart entry & start system may not be
possible immediately after reconnecting the 12-volt battery. If this hap-
pens, use the wireless 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.
However, the hybrid system will operate normally from the second
attempt.
The “POWER” switch mode is recorded by the vehicle. If the 12-volt bat-
tery is reconnected, the vehicle will return the “POWER” switch mode to
the status 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 discharge is unknown.
Restart the hybrid system, depress the brake pedal, and confirm that it is
possible to shift into each shift position.
If the system will not start even after multiple attempts at all methods above,
contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional.
