mode (with the hybrid system not operating) for more than an ho ur with the
shift lever in P, the power switch will automatically turn off. However, this func-
tion cannot entirely prevent 12-volt battery discharge. Do not leave the vehi-
cle with the power switch in ACCESSORY or ON mode for long peri ods of
time when the hybrid system is not operating.
■ Automatic hybrid system shut off feature
●The vehicle is equipped with a feature that automatically shuts off the hybrid
system when the shift lever is in P with the hybrid system oper ating for an
extended period.
● The hybrid system will automatically shut off after approximate ly 1 hour if it
has been left running while the shift lever is in P.
● The timer for the automatic hybrid system shut off feature will reset if the
brake pedal is depressed or if the shift lever is in a position other than P.
● After the vehicle is parked, if the door is locked with the door lock switch
(P. 144) from the inside or the mechanical key ( P. 507) from the outside,
the automatic hybrid system shut off feature will be disabled. The timer for
the automatic hybrid system shut off feature will be re-enabled if the driver’s
door is opened.

ditions
● When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indic ator is steady
on, as steady means the vehicle is able to move.
● When the hybrid battery (traction battery) is extremely cold (b elow approxi-
mately -22°F [-30°C]) under the influence of the outside temper ature, it may
not be possible to start the hybrid system. In this case, try t o start the hybrid
system again after the temperature of the hybrid battery increa ses due to
the outside temperature increase etc.

4086-1. Maintenance and care
●Working from top to bottom, liberally apply water to the vehicl e
body, wheel wells and underside of the vehicle to remove any di rt
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 thoroughl y
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 front of
the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle su rface,
parts (wheel, etc.) and harm your vehicle's paint.
● Vehicles with a rear spoiler: 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
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 ar eas continu-
ously.
■ When using a car wash
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, f ollow the fol-
lowing correction procedures to wash the vehicle:
● Place the key in a position 6 ft. (2 m) or more separate from t he vehicle
while the vehicle is being washed. (Take care to ensure that th e key is not
stolen.)
● Set the electronic key to battery-saving mode to disable the sm art key sys-
tem. ( P. 154)
Cleaning and prot ecting the vehicle

■ Before recharging
When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable and explosive. Therefore, observe the following precautio ns before
recharging:
● If recharging with the 12-volt battery installed on the vehicle , be sure to dis-
connect the ground cable.
● Make sure the power switch on the charger is off when connectin g and dis-
connecting the charger cables to the 12-volt battery.
■ After recharging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possi ble 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 do ors.
● 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-vol t battery is
reconnected, the vehicle will return the power switch mode to t he status it
was in before the 12-volt battery was disconnected. Make sure t o turn off
the power before disconnecting the 12-volt battery. Take extra care when
connecting the 12-volt battery if the power switch mode prior t o discharge is
unknown.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
