PRIUS_OM_OM47791U_(U)
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able
to move. For safety, apply the parking brake and make sure to shift the shift
position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction:
● The brake system operation sound heard from the front of the vehicle
when the driver’s door is opened.
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
● Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal
is depressed and accelerator is loosened.
● Other sounds, such as motors and mechanical noises, may be heard
from the brake system when the brake pedal is depressed.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent. (
P. 39)
● The operation sound of the air conditioning system (air conditioning com-
pressor, blower motor).

Hybrid battery (traction battery) air vent
There is an air intake vent on the
right side of the rear seatback for
the purpose of cooling the hybrid
battery (traction battery). If the
vent becomes blocked, the
hybrid battery (traction battery)
may overheat, leading to a
reduction in hybrid battery (trac-
tion battery) output.
Emergency shut off system When a certain level of impact is detected by the impact sensor, the
emergency shut off syst em blocks off the high voltage current and
stops the fuel pump to minimize t he risk of electrocution and fuel
leakage. If the emergency shut off sy stem activates, your vehicle will
not restart. To restart the hybrid system, contact your Toyota dealer.
Hybrid warning message
A message is automatically displa yed when a malfunction occurs in
the hybrid system or an impr oper operation is attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions. ( P. 513)

■Back door damper stays
The back door is equipped with damper stays that hold the back door in
place.
Observe the following precautions.
Failure to do so may cause damage to the back door damper stay, resulting
in malfunction.
● Do not attach any foreign objects, such
as stickers, plastic sheets, or adhesives
to the damper stay rod.
● Do not touch the damper stay rod with
gloves or other fabric items.
● Do not attach any accessories other
than genuine Toyota parts to the back

■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)
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. 350)
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
To avoid personal injury and mirror malfunction, be careful not to get your
hand caught by the moving mirror.
■ When the mirror defoggers are oper ating (vehicles with outside rear
view mirror defoggers)
Do not touch the rear view mirror surfaces, as they can become very hot and
burn you.

■
Jam protection function
If an object is detected between the moon roof and the frame while closing
or tilting down, travel is stopped and the moon roof opens slightly.
■ To reduce moon roof wind noise
When the moon roof is opened automatically, it will stop slightly before the
fully open position. Driving with the moon roof in this position can help
reduce wind noise.
■ Sunshade
The sunshade can be opened and closed manually. However, the sunshade
will open automatically when the moon roof is opened.
■ Solar Panel
The solar panel contains solar cells, and produces energy to operate the
Solar Ventilation System by receiving sunlight.
■ Moon roof open warning buzzer
The buzzer sounds when the “POWER” switch is turned off and the driver’s
door is opened with the moon roof open.
■ If the moon roof cannot be closed
If the moon roof cannot be closed, such as when the jam protection function
activates accidentally due to a malfunction, pressing and holding “CLOSE”
switch closes the moon roof.
After this, to make the automatic opening function and jam protection func-
tion available again, press and hold the “OPEN” switch until the moon roof
opens fully and then closes slightly.
If the functions do not activate, contact your Toyota dealer.

CAUTION
■SRS airbag precautions
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the airbags. Such
accessories may prevent the side airbags from activating correctly, disable
the system or cause the side airbags to inflate accidentally, resulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components.
Doing so can cause the SRS airbags to malfunction.
● Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbags have deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front 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
airbags for the front passenger may not deploy in the event of a collision.

● 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, side and rear
