When driving
■When the P position control system malfunctions
The “POWER” switch will not be able to be turned off. In such a case, the
switch can be turned off after applying the parking brake.
Have the vehicle inspected by your Toyota dealer immediately.
■Ending display
When the “POWER” switch is turned off, each of the following will be dis-
played on the multi-information display, and will extinguish after approxi-
mately 30 seconds.
●The driving distance, driving time and consumption since the hybrid sys-
tem was started.
●The odometer
●The clock
CAUTION
■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 cir-
cumstances.
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 vehi-
cle, press and hold the “POWER” switch for more than 2 seconds, or press it
briefly 3 times or more in succession. (→P. 6 0 7 )
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, but the power assist to these systems will be lost.
This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.

Driving assist systems
To h e l p e n h a n c e d r i v i n g s a f e t y and performance, the following sys-
tems operate automatically in response to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface
■Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces
■TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spin-
ning when starting the vehicle or accelerating on slippery roads
■EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
■Enhanced VSC (Enhanced Vehicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional stability when swerving on slippery road
surfaces by controlling steering performance.

PRIUS PHV_OM_OM47818U_(U)
■Sounds and vibrations caused by the ABS, brake assist, VSC and
TRAC
●A sound may be heard from the engine compartment when the hybrid
system is started, just after the vehicle begins to move, if the brake pedal
is depressed forcefully or repeatedly, or 1-2 minutes after the hybrid sys-
tem is stopped. This sound does not indicate that a malfunction has
occurred in any of these systems.
●Any of the following conditions may occur when the above systems are
operating. 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.
■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.

When driving
Hill-start assist control
■Hill-start assist control can be operated when
●The shift position is in a position other than P.
●The parking brake is not applied.
●The accelerator pedal is not depressed.
■Hill-start assist control
●While hill-start assist control is operating, the brakes remain automati-
cally applied after the driver releases the brake pedal. The stop lights and
the high mounted stoplight turn on.
●Hill-start assist control operates for about 2 seconds after the brake pedal
is released.
●If the slip indicator does not flash and the buzzer does not sound when
the brake pedal is further depressed, slightly reduce the pressure on the
brake pedal (do not allow the vehicle to roll backward) and then firmly
depress it again. If the system still does not operate, check if the operat-
ing conditions explained above have been met.
Hill-start assist control helps to prevent the vehicle from rolling
backwards when starting on an incline or slippery slope.
To e n g a g e h i l l - s t a r t a s s i s t c o n -
trol, further depress the brake
pedal when the vehicle is
stopped completely.
A buzzer will sound once to
indicate the system is acti-
vated. The slip indicator will
also start flashing.

CAUTION
■When raising your vehicle
Make sure to observe the following precautions to reduce the possibility of
death or serious injury:
●When using a floor jack, follow the instructions of the manual provided with
the jack.
●Do not use the jack that was supplied with your vehicle.
●Do not put any part of your body underneath the vehicle when it is sup-
ported only by the floor jack.
●Always use floor jack and/or automotive jack stands on a solid, flat, level
surface.
●Do not start the hybrid system while the vehicle is supported by the floor
jack.
●Stop the vehicle on level, firm ground, firmly set the park ing brake and shift
the shift position to P.
●Make sure to set the floor jack properly at the jack point.

PRIUS PHV_OM_OM47818U_(U)
CAUTION
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale (tire pressure warning light) illumi-
nates, you should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-
stitute for proper tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-inflation has not reached the
level to trigger illumination of the TPMS low tire pressure telltale (tire
pressure warning light).
Yo u r v e h i c l e h a s a l s o b e e n e q u i p p e d w i t h a T P M S ( t i r e p r e s s u r e w a r n i n g
system) malfunction indicator to indicate when the system is not operat-
ing properly. The TPMS (tire pressure warning system) malfunction indi-
cator is combined with the low tire pressure telltale (tire pressure
warning light). When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously illumi-
nated. This sequence will continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the malfunction indicator is illumi-
nated, the system may not be able to detect or signal low tire pressure
as intended.
