CAUTION
■Pre-driving check
Check that the hood is fully closed and locked.
If the hood is not locked properly, it may open while the vehicle is in motion
and cause an accident, which may result in death or serious injury.
■ After installing the support rod into the slot
Make sure the rod supports the hood securely from falling down on to your
head or body.
NOTICE
■When closing the hood
Be sure to return the support rod to its clip before closing the hood. Closing
the hood with the support rod up could cause the hood to bend.
Hold the hood open by insert-
ing the supporting rod into the
slot.STEP 4

Maintenance and care
■
After recharging/reconnecting the 12-volt battery
●Unlocking the doors using the smart key system may not be possible
immediately after reconnecting the 12-volt battery. If this happens, use
the wireless remote control or the mechanical key to lock/unlock the
doors.
● Start the EV system with the “POWER” switch in ACCESSORY mode.
The EV system may not start with the “POWER” switch turned off. How-
ever, the EV 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 the “POWER” switch off before disconnecting the 12-volt bat-
tery. Take extra care when connecting the 12-volt battery if the “POWER”
switch mode prior to discharge is unknown.
● When the 12-volt battery is reconnected, start the EV system, depress
the brake pedal, and confirm that it is possible to shift into each shift posi-
tion.
If the system will not start even after multiple attempts, contact your Toyota
dealer.
CAUTION
■ Chemicals in the 12-volt battery
The 12-volt battery contains poisonous and corrosive sulfuric acid and may
produce hydrogen gas which is flammable and explosive. To reduce the risk
of death or serious injury, take the following precautions while working on or
near the 12-volt battery:
●Do not cause sparks by touching the 12-volt battery terminals with tools.
● 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.
