head restraint moves slightly for-
ward and upward to help reduce
the risk of whiplash on the seat
occupant.

■Mirror angle can be adjusted when
The “POWER” switch is in ACCESSORY or ON mode.
■When the mirrors are fogged up (vehicles with outside rear view mirror
defoggers)
The outside rear view mirrors can be cleared using the mirror defoggers.
Turn on the rear window defogger to turn on the outside rear view mirror
defoggers. (→P. 3 7 7 )
CAUTION
■When driving the vehicle
Observe the following precautions while driving.
Failing to do so may result in loss of control of the vehicle and cause an acci-
dent, resulting in death or serious injury.
●Do not adjust the mirrors while driving.
●Do not drive with the mirrors folded.
●Both the driver and passenger side mirrors must be extended and properly
adjusted before driving.
■When a mirror is moving

hand caught by the moving mirror.
■When the mirror defoggers are operating (vehicles with outside rear
view mirror defoggers)
Do not touch the rear view mirror surfaces, as they can become very hot and
burn you.

When driving
CAUTION
●If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by your Toyota dealer
immediately.
●Do not shift the shift position to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
●Do not shift the shift position to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
●Do not shift the shift position to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
●Moving the shift position to N while the vehicle is moving will disengage
the hybrid system. Engine braking is not available with the hybrid system
disengaged.
●During normal driving, do not turn off the hybrid system. Turning the hybrid
system off while driving will not cause loss of steering or braking control,
however, power assist to the steering will be lost. This will make it more
difficult to steer smoothly, so you should pull over and stop the vehicle as
soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the
vehicle in the normal way: →P. 6 1 0
●Use engine braking (shift position B instead of shift position D) to maintain
a safe speed when driving down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. (→P. 2 4 7 )

2-1. Driving procedures
PRIUS PHV_OM_OM47856U_(U)
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain driving torque.
●Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■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 vehicle.
●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. 4 5 1 )

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 1 0 )
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, however, power assist to the steering will be lost.
This will make it more difficult to steer smoothly, 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_OM47856U_(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.
