■Mirror angle can be adjusted when
The “POWER” switch is in ACCESSORY or ON mode.
■ When the mirrors are fogged up (veh icles with outside rear view mirror
defoggers)
Turn on the mirror heaters to defog the mirrors. (P. 289)
CAUTION
■ While driving
Observe the following precautions. 
Failing to do so may result in losing control of the vehicle and cause an acci-
dent, resulting in death or serious injury.
● Do not adjust the mirrors.
● Do not drive with the mirrors folded back.
● Before driving, be sure to extend mirrors and make an adjustment prop-
erly.
■ When the mirror defogg ers are operating (vehicle with outside rear
view mirror defoggers)
Do not touch the rear view mirror surfaces, as they can become very hot and
burn you.
NOTICE
■ If ice should jam the mirror
Do not operate the control or scrape the mirror face. Use a spray de-icer to
free the mirror.

116 1-8. Safety information
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)

When driving
PRIUS_U (OM47668U) U.S.A.
CAUTION
●
Do not let the vehicle roll backwards while the shift lever is in a driving
position, or roll forward while the shift lever is in “R”. 
Doing so may cause the hybrid system not to operate or lead to poor
brake and steering performance, resulting in an accident or damage to th\
e
vehicle.
● 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,
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. 
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way: P. 496
● Use engine braking (“B”) 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. 173)
