Toyota does not recommend
towing a trailer with your vehi-
cle. Toyota also does not rec-
ommend the installation of a

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 “Accessory”, “Ignition ON” or mileage display (P. 121) is displayed on
the main display while the hybrid system is not operating, the power switch
is not off. Exit the vehicle after turning the power switch off.

PRIUS_OM_OM47F32E_(EE)■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. 131, 168)
●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 gasoline engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.

*: For good fuel economy and noise reduction, the D position should usually
be used.
P. 3 5 1
■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
highlighted 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.

■Automatic P position selection function
In the following situations, the shift position is automatically changed to P.
●When pressing the power switch with the vehicle stopped while the power
switch is in ON mode and the shift position is in a position other than P (after
the shift position has changed to P, the power switch will turn off)
*
●If the driver’s door is opened and all of the following conditions are met,
while the shift position is in a position other than P
• The power switch is in ON mode.
• The driver is not wearing the seat belt.
• The brake pedal is not depressed.
To start off the vehicle after the shift position is changed to P, operate the
shift lever again.
*: When the power switch is pressed while driving at extremely slow speeds,
such as immediately before stopping the vehicle, the shift position may
automatically change to P. Make sure that the vehicle is completely stopped
before pressing the power switch.
The shift position may also automatically switch to P if one of the following
conditions is detected while the vehicle is stopped by dynamic radar cruise
control with full-speed range (if equipped).
●Driver’s seat belt is not fastened
●Driver’s door is opened
●Approximately 3 minutes elapse after the vehicle stopped
■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. 639)
■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.
■After recharging/reconnecting the 12-volt battery

2744-3. Operating the lights and wipers
PRIUS_OM_OM47F32E_(EE)
WARNING
■Caution regarding the use of windshield wipers in AUTO mode (vehi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
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
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
■ To prevent 12-volt battery discharge
Do not leave the wipers on longer than necessary when the hybrid system
is off.
