NOTICE
■Avoiding damage to vehicle parts
● Do not turn the steering wheel fully in either direction and hold it there for
an extended period of time.
Doing so may damage the power steering motor.
● When driving over bumps in the road, drive as slowly as possible to avoid
damaging the wheels, underside of the vehicle, etc.
■ If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually depress the brake pedal to slow down the vehi-
cle.
● It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds or vibrations.
● The vehicle will lean abnormally.
Information on what to do in case of a flat tire: P. 478, 492
■ 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:
● Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer check the following:
● Brake function
● Changes in quantity and quality of oil and fluid used for the engine, hybrid
transmission, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble), and the function of all joints, bearings, etc.
If the shift control system is damaged by flooding, it may not be possible to
shift the shift position to P, or from P to other positions. When the shift posi-
tion cannot be changed from P to any other position, the front wheels will
lock, and you will be unable to tow the vehicle with the front wheels on the
ground, as the front wheels may be locked. In this case, transport the vehi-
cle with both front wheels or all four wheels lifted.

Check that the “READY” indicator is illuminated.
If the “READY” indicator changes from a flashing light to a solid light and
the buzzer sounds, the hybrid system is starting normally.
The vehicle will not move when the “READY” indicator is off.
The vehicle can move when the “READY” indicator is on even if the engine
is stopped. (The gasoline engine starts or stops automatically in accor-
dance with the state of the vehicle.)

EV drive mode
Turns EV drive mode on/off
When EV drive mode is turned on,
the EV drive mode indicator 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 [traction motor]).
■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 0C (32F) for a
long period of time etc.
●The gasoline engine is warming up.
●The hybrid battery (traction battery) is low.
The remaining battery level indicated in the energy monitor display is low.
(P. 118, 134)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
●The windshield defogger is in use.
In EV drive mode, electric power is supplied by the hybrid bat-
tery (traction battery), and only the electric motor (traction
motor) is used to drive the vehicle.
This mode allows you to drive in residential areas late at night,
or in indoor parking lots etc. without concern for noises and
exhaust gas emissions.

■ 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.
■ 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.
The remaining battery level indicated in the energy monitor display is low.
( P. 118, 134)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
When it is possible to inform the driver of automatic cancelation in advance, a
prior notice screen will appear on the multi-information display.
■ Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters
to approximately 1 km (0.6 mile). However, depending on vehicle conditions,
there are situations when EV drive mode cannot be used. (The distance that
is possible depends on the hybrid battery [traction battery] level and driving
conditions.)
■ Changing a driving mode when in EV drive mode
EV drive mode can be used in conjunction with Eco drive mode and power
mode.
However, EV drive mode may be automatically canceled when used in con-
junction with power mode.
■ Fuel economy
The hybrid system is designed to achieve the best possible fuel economy
during normal driving (using the gasol ine engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
WARNING
■ 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 vehi-
cle starting off or approaching them, so take extra care while driving.

2344-2. Driving procedures
PRIUS +_OM_OM47D30E_(EE)
*: For good fuel economy and noise reduction, the D position should usually
be used.

■When shifting the shift position to P
Fully stop the vehicle and set
the parking brake, and then
press the P position switch.
When the shift position is
changed to P, the switch indica-
tor comes on.
Check that the P position is illu-
minated on the shift position
indicator.
■
Shifting the shift position from P to other positions
●While depressing the brake pedal firmly, operate the shift lever. If
the shift lever is operated without depressing the brake pedal, the
buzzer will sound and the shifting operation will be disabled.
●When selecting the shift position, make sure that the shift posi-
tion has been changed to the desired position by checking the
shift position indicator provided on the instrument cluster.
●The shift position cannot be changed from P to B directly.

P. 213
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
• When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less than that of
other vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.
■Automatically P position selection function
When the shift position is in a position other than P, pressing the power switch
with the vehicle stopped completely will cause the shift position to change to
P automatically, and then the power switch will turn off
*.
*: If the power switch is pressed when driving at very low speeds (for exam-
ple, just before the vehicle stops), the shift position may automatically
switch to P. Press the power switch after completely stopping the vehicle to
prevent unexpected sudden stopping of the vehicle.
■If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. (P. 513)
■After recharging/reconnecting the 12-volt battery

WARNING
■When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ For the shift lever
Do not remove the shift lever knob or use anything but a genuine Toyota
shift lever knob. Also, do not hang anything on the shift lever.
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.
■ P position switch
Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at very low speeds (for
example, directly before stopping the vehicle), the vehicle may stop sud-
denly when the shift position switches to P, which could lead to an accident.

3204-5. Using the driving support systems
PRIUS +_OM_OM47D30E_(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.
