2012 TOYOTA PRIUS PHV stop start

228 2-1. Driving procedures
PRIUS PHV_OM_OM47818U_(U)
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the hybrid sys-
tem operating. This prevents the vehicle from creeping.
■ When driving the vehicle
● Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• When backing up, you may twist your body around, leading to a diffi- culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly. This allows you to depress the brake and acceler-
ator pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● Because there is no engine noise when the vehicle is being driven using
the electric motor, pedestrians in the vicinity may not notice the vehicle.
Even though the vehicle is equipped with the vehicle proximity notification
system, drive with care as pedestrians in the vicinity may still not notice
the vehicle if the surrounding area is noisy.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot
parts may cause a fire if there is any flammable material nearby.
● Do not let the vehicle roll backward while a forward driving position is\
selected, or roll forward while the shift position is in R.
Doing so may result in an accident or damage to the vehicle.

When driving
Check that the “READY” indicator is on.
If the “READY” indicator changes from a flashing light to a solid
light and the buzzer sounds, the hybrid system is starting nor-
mally.
The vehicle will not move when the “READY” indicator is off.
The vehicle can move when the “READY” indicator is on even if
the engine is stopped. (The gasoline engine starts or stops auto-
matically in accordance with the state of the vehicle.)
■
Stopping the hybrid system
Stop the vehicle completely.
Set the parking brake. ( P. 255)
Shift the shift position to P.
( P. 248)
Check that the shift position
indicator shows P. ( P. 245)
Press the “POWER” switch.
The hybrid system will stop.
Slowly release the brake pedal and check that the indicator
on the “POWER” switch is off.

When driving
■
When the P position cont rol 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. 607)
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 help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily 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 vehicl e 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 engage hill-start assist con-
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.

Interior features
■Security feature
Any unlocked doors will be automatically locked when the system is operat-
ing. The buzzer will beep and the emergency flashers flash when the doors
have been locked or the system has been turned off.
(The doors locked: Once; The system turned off: Twice)
■ Conditions aff ecting operation
 P. 1 1 9
■ When using the Remote Air Conditioning System
A charging message will be displayed on the multi-information display. Dif-
ferent messages will be displayed depending on when the Remote Air Con-
ditioning System was started (after charging or during charging).
( P. 562)
■ While the Remote Air Conditio ning System is operating
● Depending on the operating condition of the Remote Air Conditioning
System, the electric fan may spin and an operating noise may be heard.
However, this does not indicate a malfunction.
● The Remote Air Conditioning System may stop operating temporarily if
other features that use electricity (for example, the seat heater, lights,
windshield wipers) are in operation or if the charge level of the 12-volt
battery becomes low.
