CAUTION
When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
When braking
When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
If the electronically controlled assist function does not operate, do not fol-
low other vehicles closely and avoid downhill or sharp turns that require
braking.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
The brake system consists of 2 individual hydraulic systems; if one of the
systems fails, the others will still operate. In this case, the brake pedal
should be depressed more firmly than usual and the braking distance will
increase. If this happens, do not continue to drive the vehicle. If the brake
system warning light (red indicator) comes on while driving, immediately
stop the vehicle in a safe place and contact any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.

Situations where the shift position will automatically change to N:
• When the P position switch is pressed while the vehicle is running.
*1
• When an attempt is made to select the R position by moving the shift
lever when the vehicle is moving forward.
*2
• When an attempt is made to select the D position by moving the shift
lever when the vehicle is moving in reverse.
*3
• When an attempt is made to change the shift position from R to B by
moving the shift lever.
*1: Shift position may be changed to P when driving at extremely low
speeds.
*2: Shift position may be changed to R when driving at low speeds.
*3: Shift position may be changed to D when driving at low speeds.
Reverse warning buzzer
When shifting into R, a buzzer will sound to inform the driver that the shift
position is in R.
When the accelerator pedal is depressed while the shift position is in N
A buzzer will sound to inform the driver that the shift position is in N.
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 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. 522)

230 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
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 gaso-
line-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, shift the shift position to D.
When canceling Eco drive mode/power mode
Press the switch again. Also, power mode will be canceled automatically
when the “POWER” switch is turned off. However, Eco drive mode will
not be canceled automatically until the switch is pressed, even if the
“POWER” switch is turned off.
When in Eco drive mode, if the power mode switch is pressed or the
operation is reversed, the mode will switch to that of the last switch to be
pressed.
Switching the drive mode when in EV drive mode
P. 223
After recharging/reconnecting the 12-volt battery
P. 415
Customization
Settings (e.g. Reverse warning buzzer) can be changed.
(Customizable features P. 554)

232 2-1. Driving procedures
PRIUS +_OM_OM47821E_(EE)
NOTICE
Hybrid battery (traction battery) charge
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N
position selected for an extended period of time.
Situations where P position control system malfunctions are possible
If any of the following situations occurs, P position control system malfunc-
tions are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
When the “WHEN PARKING, APPLY PARKING BRAKE SECURELY”
warning message appears on the instrument cluster. (P. 473)
When the parking lock system warning light is illuminated.
When everything except the shift position indicator selection frame is illu-
minated.
When the shift position indicator remains off.
Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick suc-
cession.
The system protection function may activate and it will not be temporarily
possible to shift the shift position other than P. If this happens, please wait
for a while before attempting to change the shift position again.

Parking brake
Parking brake engaged warning buzzer
P. 469
Usage in winter time
See “Winter driving tips” for parking brake usage in winter time. (P. 319)
NOTICE
Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.
To set the parking brake, fully
depress the parking brake
pedal with your left foot while
depressing the brake pedal
with your right foot.
(Depressing the pedal again
releases the parking brake.)

Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc.
There are times when the engine speed that is displayed may differ even
when vehicle operation and driving conditions are the same.
Brightness of the instrument cluster light
If the headlight switch is turned to ON while the surrounding area is dark, the
instrument cluster lights will dim.
When disconnecting and reconnecting 12-volt battery terminals
The average fuel consumption and cruising range will be reset.
NOTICE
To prevent damage to the engine and its components
The engine may be overheating if the high coolant temperature warning light
comes on or flashes. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 528)
The trip information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information display. At extremely low temperatures, the information display
monitor may respond slowly, and display changes may be delayed.

*1: These lights turn on when the “POWER” switch is turned to the ON
mode to indicate that a system check is being performed. They will
turn off after the hybrid system is on, or after a few seconds. There
may be a malfunction in a system if a light does not come on, or if the
lights do not turn off. Have the vehicle inspected by any authorized
Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
*2: The light flashes to indicate that the system is operating.
*3: The light comes on when the system is turned off. The light flashes
faster than usual to indicate that the system is operating.
