Steering lock motor overheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from operating the engine. After about 10 seconds, the
steering lock motor will resume functioning.

NOTICE
To prevent battery discharge
Do not leave the “ENGINE START STOP” switch in ACCESSORY or IGNI-
TION ON mode for long periods of time without the engine running.
If the smart entry & start system indicator light (green) is illuminated, the
“ENGINE START STOP” switch is not off. When exiting the vehicle,
always check that the “ENGINE START STOP” switch is off.
On vehicles with a Multidrive, do not stop the engine when the shift lever is
in a position other than P. If the engine is stopped in another shift lever
position, the “ENGINE START STOP” switch will not be turned off but
instead be turned to ACCESSORY mode. If the vehicle is left in ACCES-
SORY mode, battery discharge may occur.
When starting the engine
Do not race a cold engine.
If the engine becomes difficult to start or stalls frequently, have your vehi-
cle checked by any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional immediately.
Symptoms indicating a malfunction with the “ENGINE START STOP”
switch
If the “ENGINE START STOP” switch seems to be operating somewhat dif-
ferently than usual, such as the switch sticking slightly, there may be a mal-
function. Contact any authorized Toyota dealer or repairer, or another duly
qualified and equipped professional immediately.

If the “READY” indicator does not come on
If the “READY” indicator does not come on when you press the “POWER”
switch with the shift lever in P and the brake pedal depressed, contact any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.
If the hybrid system is malfunctioning
P. 566, 568
If the electronic key battery is depleted
P. 505
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.
If the smart entry & start system or the push-button start system has
been deactivated in a customized setting
P. 682
CAUTION
When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any cir-
cumstances.
Doing so may cause an accident resulting in death or serious injury.
Caution while driving

CAUTION
Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehi-
cle, press and hold the “POWER” switch for more than 3 seconds, or press it
briefly 3 times or more in succession. (P. 650)
However, do not touch the “POWER” switch while driving except in an emer-
gency. Turning the hybrid 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 hybrid system on.
If the smart entry & start system indicator light (green) is illuminated, the
“POWER” switch is not off. When exiting the vehicle, always check that the
“POWER” switch is 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
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional 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 any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional immediately.

EV drive mode (hybrid vehicle)
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.
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 0°C (32°F)
for a long period of time etc.
The gasoline engine is warming up.
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 electric motor [trac-
tion motor]).

The hybrid battery (traction battery) is low.
• When the low traction battery indicator light came on.
• When the amount of remaining hybrid battery (traction battery) charge
displayed on the “touch screen” is low. (P. 58)
Vehicle speed is high.
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
The windshield defogger is in use.
Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically
restart in the following situations. When EV drive mode is canceled, a buzzer
will sound and the EV drive mode indicator will flash and go off.
The hybrid battery (traction battery) becomes low. (P. 58, 568)
Vehicle speed becomes high.
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
Possible driving distance when driving in EV drive mode
In EV drive mode, it is possible to drive up to about 2 km (1.3 miles) if driving
at a speed of about 45 km/h (28 mph) or less.
(The distance that is possible depends on the hybrid battery [traction battery]
level and driving conditions.)
Fuel economy
Your vehicle is designed to achieve the best possible fuel economy during
normal driving (using the gasoline engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
CAUTION
Caution while driving
When driving in EV drive mode, pay special attention to the area around the
vehicle. Because there is no engine noise, pedestrians, people riding bicy-
cles or other people and vehicles in the area may not be aware of the vehicle
starting off or approaching them, so take extra care while driving.
