WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■ When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
● Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift position to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
● Do not touch the exhaust pipe while the “READY” indicator is illuminated
or immediately after turning the hybrid system off.
Doing so may cause burns.

Meter display
When the power switch is turned off, each display will turn off as follows.
●The shift position indicator will turn off after approximately 2 seconds.
● EV driving ratio and average fuel consumption after hybrid system started,
turn off after approximately 6 seconds.
● The odometer, clock, etc. will turn off after approximately 30 seconds.
(Each display will also turn off immediately if a door is locked before 30 sec-
onds has elapsed.)
WARNING
■ 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
circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 seconds, or press
it briefly 3 times or more in succession. ( →P. 369)
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, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, 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 peri-
ods of time without the hybrid system on.
● If the hybrid system is off, but the indicator on the power switch is illumi-
nated, this indicates that the power switch is still turned on. When exiting
the vehicle, always check that the power switch is off.
■ 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. Contact any
authorized Toyota dealer or repairer, or another duly qualified and equipped
professional immediately.

■For the shift positions
●When the power switch is off, the shift position cannot be changed.
● When the power switch is in ON mode (the hybrid system is not operating),
the shift position can only be changed to N. The shift position will be
changed to N even if the shift lever is shifted to D or R and held in that posi-
tion.
● When the “READY” indicator is on, the shift position can be changed from P
to D, N or R.

In addition, if an attempt is made to change the shift position by moving the
shift lever or by pressing the P position switch in any of the following situa-
tions, the buzzer will sound and the sh ifting operation will be disabled or the
shift position will automatically change to N. When this happens, select an
appropriate shift position.
● Situations where the shifti ng operation will be disabled:
• When an attempt is made to change the shift position from P to another position by moving the shift lever without depressing the brake pedal.
• When an attempt is made to change the shift position from P or N to B by moving the shift lever.
● Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.

PRIUS +_OM_OM47B16E_(EE)
WARNING
■ Caution regarding the use of windshield wipers in AUTO mode (vehi-

the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers etc. do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid

PRIUS +_OM_OM47B16E_(EE)
■Sounds and vibrations caused by the ABS, brake assist, VSC, TRC and
hill-start assist control systems
Any of the following conditions may occur when the above systems are oper-
ating. None of these indicates that a malfunction has occurred.
●Vibrations may be felt through the vehicle body and steering.
● A motor sound may be heard after the vehicle comes to a stop.
● The brake pedal may pulsate slightly after the ABS is activated.
● The brake pedal may move down slightly after the ABS is activated.
■ ECB operating sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake pedal
is operated.
● Motor sound of the brake system heard from the front part of the vehicle
when the driver’s door is opened.
● Operating sound heard from the engine compartment when 1-2 minutes
passed after the stop of the hybrid system.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
