■To operate the system properly
Make sure to carry the electronic key when operating the system. Do not get
the electronic key too close to the vehicle when operating the system from
the outside of the vehicle.
Depending on the position and holding condition of the electronic key, the
key may not be detected correctly and the system may not operate properly.
(The alarm may go off accidentally, or the door lock prevention may not func-
tion.)
■ If the smart key system does not operate properly
● Locking and unlocking the doors: Use the mechanical key. ( P. 468)
● Starting the EV system. ( P. 468)
■ Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The battery becomes depleted
even if the electronic key is not used.) If the smart key system or the
wireless remote control function does not operate, or the detection area
becomes smaller, the battery may be depleted. Replace the battery when
necessary. ( P. 383)
● If the battery becomes low, an alarm will sound in the cabin when the EV
system stops. (P. 100)
● To avoid serious deterioration, do not leave the electronic key within 3 ft.
(1 m) of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Induction cookers
• Table lamps

■For efficient use
●Shift the shift position to D when driving.
In the N position, energy cannot be regenerated during deceleration.
● Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration.
● Avoid repeated acceleration.
Repeated acceleration consumes traction battery energy, resulting in
reduced vehicle performance, including driving range.

■
When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle.
●Short in electrical components
● Traction battery damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Toyota dealer check the following.
● Brake function
● Changes in quantity and quality of transmission fluid and so forth.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
● If the P position control system is damaged by flooding, it may not be pos-
sible to shift the shift position to P, or from P to other positions. When the
shift position cannot be changed from P to any other position, the front
wheels will lock, and moving the vehicle with the front wheels on the
ground will not be possible. In this case, move the vehicle with both front
wheels or all four wheels lifted.

When driving
CAUTION
■
When starting the EV system
Always start the EV system while sitting in the driver’s seat. Do not depress
the accelerator pedal while starting the EV system under any circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the EV system in an emergency
If you want to stop the EV system in an emergency while driving the vehi\
cle,
press and hold the “POWER” switch for more than 2 seconds, or press it
briefly 3 times or more in succession. ( P. 479)
However, do not touch the “POWER” switch while driving except in an emer-
gency. Turning the EV system off while driving will not cause loss of steering
or braking control, but the power assist to these systems will be lost. This will
make it more difficult to steer and brake, so you should pull over and stop
the vehicle as soon as it is safe to do so.
NOTICE
■ To prevent 12-volt battery discharge
Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the EV system on.
■ When starting the EV system
●Do not depress the accelerator pedal unnecessarily.
● If the EV system becomes difficult to start, have your vehicle checked by
your Toyota dealer immediately.
