PRIUS_U (OM47668U) U.S.A.Your vehicle is equipped with “ADVANCED AIRBAGS” designed
based on US motor vehicle safety standards (FMVSS208). The air-
bag system controls airbag deploym
ent power for the driver and front
passenger. The driver airbag system consists of the driver seat’s
position sensor etc. The front pass enger’s airbag system consists of
the front passenger occupant classification sensor etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag sensor assembly. The
airbag sensor assembly consists of a safing sensor and an airbag
sensor.
In certain types of severe frontal or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to hel p restrain the motion
of the occupants.
■ If the SRS airbags deploy (inflate)
● Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
● The windshield may crack.
● For Safety Connect subscribers, if the SRS airbags deploy or in the event
of a severe rear-end collision, the system is designed to send an emer-
gency call to the response center, notifying them of the vehicle’s location
(without needing to push the “SOS” button) and an agent will attempt to
speak with the occupants to ascertain the level of emergency and assis-
tance required. If the occupants are unable to communicate, the agent
automatically treats the call as an emergency and helps to dispatch the
necessary emergency services. ( P. 395)

CAUTION
■
SRS airbag precautions
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front, center and rear pillar garnishes, are damaged or cracked,
have them replaced by your Toyota dealer.
● Do not place anything, such as a cushion, on the front passenger’s seat.
Doing so will disperse the passenger’s weight, which prevents the sensor
from detecting the passenger’s weight properly. As a result, the SRS front
passenger airbag may not deploy in the event of a collision.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perfo rm any of the following modifications
without consulting your Toyota dealer. 
The SRS airbag may malfunction or deploy (inflate) accidentally, causing
death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, center and
rear pillars or roof side rail
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment
● Installation of snow plows, winches, etc. to the front grille (bull bars, kan-
garoo bar etc.)
● Modifications to the vehicle’s suspension system
● Installation of electronic devices such as mobile two-way radios or CD
players
● Modifications to your vehicle for a person with a physical disability

Turning on the high beam headlights
With the headlights on, push
the lever forward to turn on the
high beams.
Pull the lever back to the center
position to turn the high beams
off.
Pull the lever toward you to
turn on the high beams.
Release the lever to turn them off.
You can flash the high beams
with the headlights on or off.
ITO23P104a
■Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the hybrid system is started
and the parking brake is released. Daytime running lights are not designed
for use at night.
■ Headlight control sensor (if equipped)
The sensor may not function properly if
an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to
the windshield. 
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight con-
trol system to malfunction.

208 2-3. Operating the lights and windshield wipers
PRIUS_U (OM47668U) U.S.A.
■Automatic light off system
● When the headlights are on: The headlights and tail lights turn off 30 sec-
onds after a door is opened and closed if the “POWER” switch has been
switched to ACCESSORY mode or OFF.
● When only the tail lights are on: The tail lights turn off automatically if the
“POWER” switch is switched to ACCESSORY mode or OFF and driver’s
door is opened.
To turn the lights on again, turn the “POWER” switch to ON mode, or turn the
light switch off once and then back to the
or position.
■ Automatic headlight leveling system (vehicles with LED headlights)
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
■ If the indicator flashes... (vehicles with LED headlights)
It may indicate a malfunction in the system. Contact your Toyota dealer.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. light sensor sensitivity) can be changed. 
(Customizable features P. 587)
NOTICE
■To prevent 12 volt battery discharge
Do not leave the lights on longer than necessary if the hybrid system is not
operating.

222 2-4. Using other driving systems
PRIUS_U (OM47668U) U.S.A.
Driving in vehicle-to-vehicle distance control modeThis mode employs a sensor to detect the presence of vehicles up to
approximately 400 ft. (120 m) ahead and to judge the distance
between your vehicle and those the vehicle ahead of you.
Note that vehicle-to-vehicle distance will close in when traveling on long
downhill slopes.

■Dynamic radar cruise control can be set when
● The shift position is in “D”.
● Vehicle speed is above approximately 30 mph (50 km/h).
■ Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-
vehicle distance control mode has been used. The mode also cannot be
switched from constant speed control to vehicle-to-vehicle distance control
mode. Turn the system off by pressing the “ON-OFF” button, and turn it on
again.
■ Accelerating
The vehicle can accelerate normally. After acceleration, the set speed
resumes. However, during vehicle-to-vehicle distance control mode, the
vehicle speed may decrease below the set speed in order to maintain the
distance to the vehicle ahead.
■ Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the
following situations:
● Actual vehicle speed falls below approximately 25 mph (40 km/h).
● Enhanced VSC is activated.
● The sensor cannot operate correctly because it is covered in some way.
● The windshield wipers are operating at high speed.
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact your Toyota
dealer.
