■Electronic key battery depletion
●The standard battery life is 1 to 2 years.
● If the battery becomes low, an alarm will sound in the cabin when the
hybrid system stops. (P. 451)
● As the electronic key always receives radio waves, the battery will
become depleted even if the electronic key is not used. The following
symptoms indicate that the electronic key battery may be depleted.
Replace the battery when necessary. ( P. 399)
• The smart key system or the wireless remote control does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● 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
■ When the electronic key battery is fully depleted
P. 399
■ If the smart key system has been d eactivated in a customized setting
● Locking and unlocking the doors: Use the wireless remote control or
mechanical key. ( P. 61, 475)
● Starting the hybrid system and changing “POWER” switch modes:
P. 475
● Stopping the hybrid system: P. 476
■ Customization that can be co nfigured at Toyota dealer
Settings (e. g. operation signals) can be changed.
(Customizable features: P. 518)

150 2-1. Driving procedures
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 494)
■ For efficient use
●Shift the shift lever to D when driving.
In the N position, the gasoline engine operates but electricity cannot be
generated. The hybrid battery (traction battery) will discharge, requiring
unnecessary engine power to recharge.
● Drive your vehicle smoothly.
Avoid abrupt acceleration and deceleration. Gradual acceleration and
deceleration will make more effective use of the electric motor (traction
motor) without having to use gasoline engine power.
● Avoid repeated acceleration.
Repeated acceleration consumes hybrid battery (traction battery) power,
resulting in poor acceleration. Battery power can be restored by driving
with the accelerator pedal slightly released.
● Shift the shift lever to P when parking.
In the N position, the hybrid battery (traction battery) does not recharge.
Leaving the shift lever in the N position for an extended period of time
may discharge the hybrid battery. The vehicle cannot run if the hybrid
battery is discharged.

NOTICE
■
To prevent 12-volt battery discharge
Do not leave the engine switch in the “ACC” or “ON” position for long periods
of time without the hybrid system on.
■ When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by
your Toyota dealer immediately.

When stopping the hybrid system with the shift lever in a
position other than P
If the hybrid system is stopped with the shift lever in a position other
than P, the “POWER” switch will not be turned off but instead be
turned to ACCESSORY mode. Perform the following procedure to
turn the switch off:
Check that the parking brake is set.
Shift the shift lever to P.
Check that is displayed on the multi-information dis-
play and then press the “POWER” switch once.
Check that on the multi- information display is off.
■Auto power off function
When the shift lever is in P, if the vehicle is left in ACCESSORY or ON mode
with the hybrid system not operating for more than 20 minutes (ACCES-
SORY mode) or one hour (ON mode), the “POWER” switch will automati-
cally turn off. However, this function cannot entirely prevent 12-volt battery
discharge. Do not leave the vehicle with the “POWER” switch in ACCES-
SORY or ON mode for long periods of time when the hybrid system is not
operating.

■ If the electronic key battery is depleted
P. 399
■ Operation of the “POWER” switch
●When operating the “POWER” switch, one short, firm press is enough. If
the switch is pressed improperly, the hybrid system may not start or the
“POWER” switch mode may not change. It is not necessary to press and
hold the switch.
● If attempting to restart the hybrid system immediately after turning the
“POWER” switch off, the hybrid system may not start in some cases.
After turning the “POWER” switch off, please wait a few seconds before
restarting the hybrid system.

■
To prevent 12-volt battery discharge
●Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the hybrid system on.
● If is displayed on the multi-information display, the “POWER”
switch is not off. Exit the vehicle after turning the “POWER” switch off.
● Do not stop the hybrid system when the shift lever is in a position other
than P. If the hybrid system is stopped in another shift lever position, the
“POWER” switch will not be turned off but instead be turned to ACCES-
SORY mode. If the vehicle is left in ACCESSORY mode, 12-volt battery
discharge may occur.
■ When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by
your Toyota dealer immediately.
■ Symptoms indicating a malfunction with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Con-
tact your Toyota dealer immediately.

2-1. Driving procedures
EV drive mode
In EV drive mode, the electric motor (traction motor), powered by the
hybrid battery (traction battery), is used to drive the vehicle.
This mode allows you to drive in residential areas early in the morn-
ing and late at night, or in indoor parking lots etc. without concern
for noises and exhaust gas emissions.
Turns EV drive mode on/off
When EV drive mode is turned
on, the EV drive mode indica-
tor will come on.
Pressing the switch when in
EV drive mode will return the
vehicle to normal driving (using
the gasoline engine and elec-
tric motor [traction motor]).

■
Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline
engine will start automatically after a short period of time in order to warm
up. In this case, you will become unable to switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illumi-
nated, press the EV drive mode switch before the gasoline engine starts to
switch to EV drive mode.
■ Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If
it cannot be turned on, a buzzer will sound and a message will be shown on
the multi-information display.
●The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high
speeds, etc.
● The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 68
F (20C)
for a long period of time etc.
● The gasoline engine is warming up.
● The hybrid battery (traction battery) is low.
When the amount of remaining hybrid battery (traction battery) charge
displayed on the meter or Display Audio system is low. ( P. 35)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.
