■Automatic car washes
●Fold the mirrors before washing
the vehicle.
Start washing from the front of the
vehicle. Extend the mirrors before
driving.
●Turn off the power back door (if
equipped).
●Brushes used in automatic car
washes may scratch the vehicle surface, parts (wheel, etc.) 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
As water may enter the cabin, do
not bring the nozzle tip near the
gaps around the doors or perimeter
of the windows, or spray these
areas continuously.

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 following correction pro-
cedures 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 system. ( P.140)
■Wheels and wheel ornaments
●Remove any dirt immediately by
using a neutral detergent.
●Wash detergent off with water
immediately after use.
●To protect the paint from damage,
make sure to obs erve the follow-
ing precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such
as after driving or parking in hot
weather
■Brake pads and calipers

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

●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 status it was in
before the 12-volt battery was dis-
connected. Make sure to turn off
the power switch before discon-
necting the 12-volt battery. Take
extra care when connecting the
12-volt battery if the power switch
mode prior to discharge is
unknown.
●When the 12-volt b attery is recon-
nected, start the hybrid system,
depress the brake pedal, and con-
firm that it is possible to shift into
each shift position.
If the system will not start even after
multiple attempts, contact your Toy-
