PRIUS v_OM_OM47B23U_(U)The SRS airbag and seat belt pretensioner devices in your Toyota contain
explosive chemicals. If the vehicle is scrapped with the airbags and seat belt
pretensioners left as they are, this may cause an accident such as fire. Be
sure to have the systems of the SRS airbag and seat belt pretensioner
removed and disposed of by a qualified service shop or by your Toyota dealer
before you scrap your vehicle.
Special handling may apply,
See www.dtsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These compo-
nents may include airbag, seat belt pretensioners, and wireless remote con-
trol batteries.

WARNING
■
General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that
distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regard ing children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the windows or other features of the vehicle. In addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

781-2. Hybrid system
PRIUS v_OM_OM47B23U_(U)
Hybrid system precautions
The illustration is an example for explanation and may differ from the
actual item.
Take care when handling the hybrid system, as it is a high volt-
age system (about 650V at maximum) as well as contains parts
that become extremely hot when the hybrid system is operating.
Obey the warning labels attached to the vehicle.

Instrument cluster
■Remaining hybrid battery (tract ion battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or el ectricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may not
reach the highest level (level 8). However, this does not indicate a malfunc-
tion.
■ Engine speed
On hybrid vehicles, engine speed is precisely controlled in order to help
improve fuel efficiency and reduce exhaust emissions etc.
■ Brightness of the instrument panel light
If the headlight switch is turned to ON while the surrounding area is dark, the
instrument panel lights will dim.
■ When disconnecting and reconnect ing 12-volt battery terminals
The fuel consumption display and average vehicle speed 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. 546)
■ 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.

4-2. Driving procedures
NOTICE
■Hybrid battery (tract ion 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 shift control system malfunctions are possible
If any of the following situations occurs, shift control system malfunctions
are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact your Toyota dealer.
● Vehicles without multi-information display:
When the “P LOCK MALFUNCTION W H E N PA R K I N G, PA R K I N F L AT
PLACE AND APPLY PARKING BRAKE SECURELY” warning message
appears on the instrument cluster. ( P. 494)
● Vehicles without multi-information display:
When the parking lock system warning light is illuminated.
● Vehicles with multi-information display:
When the warning message indicating the shift control system appears on
the multi-information display. ( P. 508)
● 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 approximately 20 seconds before attempting to change the shift position
again.

4-5. Using the driving support systems
Driving assist systems
◆ECB (Electronically Controlled Brake System)
The electronically controlled system generates braking force corre-
sponding to the brake operation
◆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
spinning when starting the vehicle or accelerating on slippery roads
◆EPS (Electric Power Steering)
Employs an electric motor to redu ce the amount of effort needed to
turn the steering wheel
◆Enhanced VSC (Enhanced Ve hicle Stability Control)
Provides cooperative control of the ABS, TRAC, VSC and EPS.
Helps to maintain directional st ability when swerving on slippery
road surfaces by controllin g steering performance.
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

(If equipped)
P position request indicator light (warning buzzer)
The amount of charge remaining in the hybrid battery
(traction battery) has fallen because the shift position has
been left in N for a long time
 Because recharging is not possible when the shift
position is in N, shift the shift position to P when
parking the vehicle for a long time.

 Shift the shift position to P.
(If equipped)
Hybrid system overheat warn ing light (warning buzzer)
The hybrid system has overheated
This light may come on when driving under severe operat-
ing conditions, and the output of the hybrid system may
temporarily decrease in order to protect the system. (For
example, when driving up a long steep hill or driving up a
steep hill in reverse.)
 Stop and check. ( P. 546)
