SRS warning light
Driver airbag
Airbag manual on-off switch
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. As the airbags
deploy, a chemical reaction in the inflators quickly fills the airbags with non-
toxic gas to help restrain the motion of the occupants.
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the extremely high speed
deployment (inflation) by hot gases.
●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, parts of the
front and rear pillars, and roof side rails, may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.
●The hybrid system will be stopped and fuel supply to the engine will be stopped. ( P.82)
●The brakes and stop lights will be con- trolled automatically. ( P.277)
●The interior lights will turn on automat- ically. ( P.296)
●The emergency flashers will turn on automatically. ( P.366)
●Vehicles with eCall: If any of the fol-
lowing situations occur, the system is
designed to send an emergency call* to the eCall control 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 assistance required. If the occupants are unable to communicate, the agent automati-
cally treats the call as an emergency and helps to dispatch the necessary
emergency services. ( P.66)
• An SRS airbag is deployed. • A seat belt pretensioner is activated.• The vehicle is involved in a severe
rear-end collision.*: In some cases, the call cannot be
made. ( P. 6 7 )
■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set threshold level (the level of
force corresponding to an approxi- mately 20 - 30 km/h [12 - 18 mph] frontal collision with a fixed wall that
does not move or deform).
However, this threshold velocity will be
considerably higher in the following situ-
ations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole,
which can move or deform on impact • If the vehicle is involved in an under-ride collision, such as a collision in
which the front of the vehicle “under- rides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possible that only the seat belt
pretensioners will activate.
■SRS airbag deployment conditions (SRS side and curtain shield air-bags and SRS front seat center air-
bags)
●The SRS side and curtain shield air-
bags and SRS front seat center air- bags will deploy in the event of an

Exhaust gas precautions
Harmful substance to the
human body is included in
exhaust gases if inhaled.
WARNING
Exhaust gases include harmful car-
bon monoxide (CO), which is color- less and odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to an accident caused by light-
headedness, or may lead to death or a serious health hazard.
■Important points while driving
●Keep the back door closed.
●If you smell exhaust gases in the vehicle even when the back door is closed, open the windows and have
the vehicle inspected at any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer as soon as possible.
■When parking
●If the vehicle is in a poorly venti- lated area or a closed area, such as a garage, stop the hybrid system.
●Do not leave the vehicle with the hybrid system on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space and ensure that
exhaust fumes do not enter the vehicle interior.
●Do not leave the hybrid system operating in an area with snow build-up, or where it is snowing. If
snowbanks build up around the vehicle while the hybrid system is operating, exhaust gases may col-
lect and enter the vehicle.
■Exhaust pipe
The exhaust system needs to be checked periodically. If there is a hole
or crack caused by corrosion, dam- age to a joint or abnormal exhaust noise, be sure to have the vehicle
inspected and repaired by any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer.

■System components
The illustration is an example for explanation and may differ from the actual item.
Gasoline engine
Electric motor (traction motor)
■When stopped/during start off
The gasoline engine stops* when
the vehicle is stopped. During start
off, the electric motor (traction
motor) drives the vehicle. At slow
speeds or when traveling down a
gentle slope, the engine is stopped*
and the electric motor (traction
motor) is used.
When the shift lever is in N, the
Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics differ ent from
conventional vehicles. Be sure you are closely familiar with th e
characteristics of your vehic le, and operate it with care.
The hybrid system combines the use of a gasoline engine and an
electric motor (traction motor) according to driving conditions,
improving fuel efficiency and reducing exhaust emissions.

1-4. Hybrid system
For safety and security
hybrid battery (traction battery) is
not being charged.
*: When the hybrid battery (traction bat-
tery) requires charging or the engine
is warming up, etc., the gasoline
engine will not automatically stop.
( P. 7 7 )
■During normal driving
The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the hybrid
battery (traction battery) as neces-
sary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of the
hybrid battery (traction battery) is
added to that of the gasoline engine
via the electric motor (traction
motor).
■When braking (regenerative
braking)
The wheels operate the electric
motor (traction motor) as a power
generator, and the hybrid battery
(traction battery) is charged.
■Regenerative braking
●In the following situations, kinetic energy is converted to electric energy
and deceleration force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery). • The accelerator pedal is released while driving with the shift lever in D or
B. • The brake pedal is depressed while driving with the shift lever in D or B.
●Vehicles with GPF system: While the GPF system ( P.276) is operating to
regenerate the exhaust gas filter, the
hybrid battery (traction battery) may not be recharged.
■EV indicator
The EV indicator comes on when the
vehicle is driven using only the electric motor (traction motor) or the gasoline engine is stopped.
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automatically. However, it may not stop automatically in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the heater is switched on
Depending on the circumstances, the gasoline engine may also not stop auto-
matically in other situations.
■Charging the hybrid battery (trac- tion battery)
As the gasoline engine charges the
hybrid battery (traction battery), the bat- tery does not need to be charged from an outside source. However, if the vehi-
cle is left parked for a long time the hybrid battery (traction battery) will slowly discharge. For this reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or 16 km (10 miles). If the hybrid battery
(traction battery) becomes fully dis- charged and you are unable to start the hybrid system, contact any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.

■Charging the 12-volt battery
 P. 4 1 1
■After the 12-volt battery has dis- charged or when the terminal has been removed and installed during
exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the
hybrid battery (traction battery). If this continues for a few days, contact any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibra- tion even though the vehicle is able to move with the “READY” indicator is illu-
minated. For safety, apply the parking brake and make sure to shift the shift lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is operat-ing and are not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) under the
rear seats when the hybrid system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the hybrid battery (traction battery),
under the rear seats, when the hybrid system is started or stopped.
●Sounds from the hybrid system may be heard when the back door is open.
●Sounds may be heard from the trans-mission 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 regener-
ative braking when the brake pedal is depressed or as the accelerator pedal is released.
●Vibration may be felt when the gaso-
line engine starts or stops.
●Cooling fan sounds may be heard
from the air intake vent on the side of the lower part of the rear left seat.
■Maintenance, repair, recycling, and disposal
Contact any authorized Toyota retailer or Toyota authorized repairer, or any reli-able repairer regarding maintenance,
repair, recycling and disposal. Do not dispose of the vehicle yourself.
■Customization
Some functions can be customized.
( P.431)
When the gasoline engine is off
while driving, a sound is produced
to warn pedestrians, people riding
bicycles or other people and vehi-
cles in the surrounding area that
the vehicle is approaching. The
pitch of the sound adjusts accord-
ing to vehicle speed. When vehicle
speed is approximately 25 km/h (16
mph) or more, the warning system
turns off.
■Acoustic vehicle alerting system
In the following cases, the acoustic vehi- cle alerting system sound may be diffi-
cult for pedestrians, people riding bicycles or other people and vehicles in the surrounding area to hear:
●When there is a lot of noise in the vicinity
●When it is raining or during strong winds
●When in the area surrounding the rear of the vehicle, rather than in front of
the vehicle
