QIf the plug-in hybrid system operation mode cannot be changed
In the following situations, the plug-in hybrid system operation mode cannot
be changed even if the EV/HV mode selection switch or EV City mode switch
is pressed. (In this case, the warning message is displayed on the multi-infor-
mation display when the switch is pressed.)
OWhen electricity needed for EV driving is not remaining (when in EV/EV City
mode)
OWhen the traction battery is almost completely charged (hybrid battery [trac-
tion battery] charge mode)
QWhen EV City mode is canceled
When EV City mode is canceled, either automatically or by pressing the EV
City mode switch, while the accelerator pedal is depressed, the drive torque
and vehicle speed may increase even if the accelerator pedal is maintained
at a fixed position. When EV City mode is canceled, a buzzer will sound and
the EV City mode indicator will flash and go off.
QWhen switching from EV mode to another mode using the switch
When the power switch is turned off, operation mode switching is canceled
and the system returns to EV mode the next time the vehicle is started.
QHybrid battery (traction battery) charge mode
OThe following may occur to protect the system, etc.
• Cannot switch to hybrid battery (traction battery) charge mode or cannot
cancel it
• Gasoline engine does not start or stops even after switching to hybrid bat-
tery (traction battery) charge mode
OIf a load to the system is large, such as when the power consumption of the
air conditioning system is large or when the temperature of the engine cool-
ant is high, it may take longer time than usual to charge using the hybrid bat-
tery (traction battery) charge mode, or charging to the hybrid battery
(traction battery) may not be performed.

Plug-in hybrid vehicle driving tips
XUsing EV mode and HV mode effectively
Primarily using EV mode when driving in cities and using HV mode
when driving on highways (or freeways) can help conserve fuel and
electricity. (P. 88)
XUsing EV City mode
When using EV City mode, the motor output is limited and the oper-
ation of the gasoline engine can be minimized. Therefore, the vehi-
cle can be driven with only electric motor (traction motor) in city
areas, etc. (P. 88)
XUsing Eco drive mode
When using Eco drive mode, the torque corresponding to the accel-
erator pedal depression amount can be generated more smoothly
than it is in normal conditions. In addition, the operation of the air
conditioning system (heating/cooling) will be minimized, improving
fuel and electricity economy. (P. 418)
XUse of Hybrid System Indicator
Eco-friendly driving is possible by keeping the Hybrid System Indi-
cator within Eco area. (P. 226)
XShift position operation
Shift the shift position to D when stopped at a traffic light, or driving
in heavy traffic etc. Shift the shift position to P when parking. When
using the N, there is no positive effect on fuel consumption. In the
N, the gasoline engine operates but electricity cannot be gener-
ated. Also, when using the air conditioning system, etc., the hybrid
battery (traction battery) power is consumed.
For economical and ecological driving, pay attention to the fol-
lowing points:

Driving
Normal mode
Suitable for normal driving.
When normal mode is selected, the “ECO MODE” and “PWR MODE”
indicators turn off.
Power mode
Suitable for when crisp handling and enhanced accelerator
response are desired, such as when driving on mountainous roads.
When power mode is selected, the “PWR MODE” indicator will illumi-
nate on the main display.
Eco drive mode
Suitable for driving that improves fuel economy by generating
torque in response to accelerator pedal operations more smoothly
than in normal mode.
When Eco drive mode is selected, the “ECO MODE” indicator will illumi-
nate on the main display.
While the air conditioning is being used, the fan speed setting mode will
be changed to “ECO” mode automatically (P. 526), allowing for driving
that leads to even better fuel economy.
QAutomatic deactivation of power mode
OPower mode will be canceled and changed to normal mode automatically
when the power switch is turned off.
OHowever, normal mode and eco drive mode will not be canceled automati-
cally until the switch is pressed, even if the power switch is turned off.

Maintenance and care
WARNING
QReplacing a tire
O Do not touch the disc wheels or the area around the brakes immediately
after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the
brakes will be extremely hot. Touching these areas with hands, feet or
other body parts while changing a tire, etc. may result in burn s.
O Failure to follow these precautions could cause the wheel nuts to loosen
and the tire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench to 103 N•m
(10.5 kgf•m, 76 ft•lbf) as soon as possible after changing wheels .
• When installing a tire, only use wheel nuts that have been spe cifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nu t threads or
bolt holes of the wheel, have the vehicle inspected by any auth orized
Toyota retailer or Toyota author ized repairer, or any reliable repairer.
• When installing the wheel nuts, be sure to install the wheel n uts with the
tapered ends facing inward.

6207-3. Do-it-yourself maintenance
Prius Plug-in Hybrid_OM_OM47E75E_(EE)
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come
off.
Install the tire and loosely
tighten each wheel nut by hand
by approximately the same
amount.
Turn the wheel nuts until the wash-
ers come into contact with the disc
wheel.
Lower the vehicle.
Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
Tightening torque:
103 N•m (10.5 kgf•m, 76 ft•lbf)
Stow the tire jack and all tools.
