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

■For fuel-efficient driving
Keep in mind that hybrid vehicles are similar to conventional vehicles, and it is necessary to refrain from activities such
as sudden acceleration. ( P.282)
■Driving in the rain
●Drive carefully when it is raining,
because visibility will be reduced, the windows may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be
especially slippery.
●Refrain from high speeds when driv-
ing on an expressway in the rain, because there may be a layer of water between the tires and the road sur-
face, preventing the steering and brakes from operating properly.
■Restraining the hybrid system out-put (Brake Override System)

4-1. Before driving
WARNING
●The driver should pay extra atten- tion to pedestrians when the vehicle
is powered only by the electric motor (traction motor). As there is no engine noise, the pedestrians
may misjudge the vehicle’s move- ment.
●Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. These hot parts may cause a fire if there is
any flammable material nearby.
●During normal driving, do not turn
off the hybrid system. Turning the hybrid system off while driving will not cause loss of steering or brak-
ing control, however, power assist to the steering will be lost. This will make it more difficult to steer
smoothly, so you should pull over and stop the vehicle as soon as it is safe to do so.
In the event of an emergency, such as if it becomes impossible to stop the vehicle in the normal way:
 P. 3 6 6
●Use engine braking (shift position
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.181)
●Do not adjust the positions of the steering wheel, the seat, or the inside or outside rear view mirrors
while driving. Doing so may result in a loss of vehicle control.
●Always check that all passengers’ arms, heads or other parts of their
body are not outside the vehicle.
■When driving on slippery road surfaces
●Sudden braking, acceleration and
steering may cause tire slippage and reduce your ability to control the vehicle.
●Sudden acceleration, engine brak-ing due to shifting, or changes in
engine speed could cause the vehi- cle to skid.
●After driving through a puddle, lightly depress the brake pedal to make sure that the brakes are func-
tioning properly. Wet brake pads may prevent the brakes from func-tioning properly. If the brakes on
only one side are wet and not func- tioning properly, steering control may be affected.
■When shifting the shift lever
●Do not let the vehicle roll backward
while a forward driving position is selected, or roll forward while the shift lever is in R.
Doing so may result in an accident or damage to the vehicle.
●Do not shift the shift lever to P while the vehicle is moving.Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to R while the vehicle is moving forward.Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to a driv-ing position while the vehicle is moving backward.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.

WARNING
●Do not leave a door or window open if the curved glass is coated
with a metallized film such as a sil- ver-colored one. Reflected sunlight may cause the glass to act as a
lens, causing a fire.
●Always apply the parking brake,
shift the shift lever to P, stop the hybrid system and lock the vehicle.Do not leave the vehicle unat-
tended while the hybrid system is operating.If the vehicle is parked with the shift
lever in P but the parking brake is not set, the vehicle may start to move, possibly leading to an acci-
dent.
●Do not touch the exhaust pipes
while the “READY” indicator is illu- minated or immediately after turn-ing the hybrid system off.
Doing so may cause burns.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the shift lever or depress the acceler-
ator pedal, this could cause an acci- dent or fire due to hybrid system overheating. Additionally, if the vehi-
cle is parked in a poorly ventilated area, exhaust gases may collect and enter the vehicle, leading to death or
a serious health hazard.
■When braking
●When the brakes are wet, drive more cautiously.Braking distance increases when
the brakes are wet, and this may cause one side of the vehicle to brake differently than the other
side. Also, the parking brake may not securely hold the vehicle.
●If the electronically controlled brake system does not operate, do not fol-low other vehicles closely and avoid
hills or sharp turns that require braking.In this case, braking is still possible,
but the brake pedal should be depressed more firmly than usual. Also, the braking distance will
increase. Have your brakes fixed immediately.
●The brake system consists of 2 or more individual hydraulic systems; if one of the systems fails, the
other(s) will still operate. In this case, the brake pedal should be depressed more firmly than usual
and the braking distance will increase. Have your brakes fixed immediately.
■If the vehicle becomes stuck
Do not spin the wheels excessively
when a driven wheel is up in the air, or the vehicle is stuck in sand, mud, etc. This may damage the driveline
components or propel the vehicle for- ward or backward, causing an acci-dent.
NOTICE
■When driving the vehicle
●Do not depress the accelerator and brake pedals at the same time
during driving, as this may restrain the hybrid system output.
●Do not use the accelerator pedal or depress the accelerator and brake pedals at the same time to hold the
vehicle on a hill.
■When parking the vehicle
Always set the parking brake and shift the shift lever to P. Failure to do so may cause the vehicle to move or the
vehicle may accelerate suddenly if the accelerator pedal is accidentally depressed.

4-1. Before driving
Driving
Avoid sudden braking that may
cause skidding. Otherwise, the
vehicle may spin out of control. This
is especially true when driving on
wet or slippery road surfaces.
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor-
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre-
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut-
ing lane changes.
■Transmission information
To maintain engine braking effi-
ciency and charging system perfor-
mance when using engine braking,
do not use the transmission in D.
( P.181)
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( P.414)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.

enabled, the system will turn off and the
brake hold standby indicator light will go off. In addition, if any of the conditions are detected while the system is holding
the brake, a warning buzzer will sound and a message will be shown on the multi-information display. The parking
brake will then be set automatically.
■Brake hold function
●If the brake pedal is left released for a
period of about 3 minutes after the system has started holding the brake, the parking brake will be set automati-
cally. In this case, a warning buzzer sounds and a message is shown on the multi-information display.
●To turn the system off while the sys-tem is holding the brake, firmly
depress the brake pedal and press the button again.
●The brake hold function may not hold the vehicle when the vehicle is on a steep incline. In this situation, it may
be necessary for the driver to apply the brakes. A warning buzzer will sound and the multi-information dis-
play will inform the driver of this situa- tion. If a warning message is shown on the multi-information display, read
the message and follow the instruc- tions.
■When the parking brake is set auto-matically while the system is hold-
ing the brakes
Perform any of the following operations to release the parking brake.
●Depress the accelerator pedal. (The parking brake will not be released
automatically if the seat belt is not fas- tened.)
●Operate the parking brake switch with the brake pedal depressed.
Make sure that the parking brake indica-
tor light goes off. ( P.184)
■When an inspection at any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer is necessary
When the brake hold standby indicator (green) does not illuminate even when the brake hold switch is pressed with the
brake hold system operating conditions met, the system may be malfunctioning. Have the vehicle inspected at any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■If “Brake Hold Malfunction Press
Brake to Deactivate Visit Your Dealer” or “Brake Hold Malfunction Visit Your Dealer” is displayed on
the multi-information display
The system may be malfunctioning. Have the vehicle inspected by any
authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Warning messages and buzzers
Warning messages and buzzers are used to indicate a system malfunction or to inform the driver of the need for cau-
tion. If a warning message is shown on the multi-information display, read the message and follow the instructions.
■If the brake hold operated indicator
flashes

WARNING
■When the vehicle is on a steep
incline
When using the brake hold system on a steep incline, exercise caution. The
brake hold function may not hold the vehicle in such a situation.
■When stopped on a slippery road
The system cannot stop the vehicle when the gripping ability of the tires
has been exceeded. Do not use the system when stopped on a slippery road.

The system can detect the follow-
ing (The detectable objects differs
depending on the function.):
 Vehicles
 Bicyclists
 Pedestrians
■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.
■Emergency steering assist
If the system determines that the
possibility of a collision with a
pedestrian is high and that there is
sufficient space for the vehicle to be
PCS (Pre-Collision Sys-
tem)*
The pre-collision system uses
a radar sensor and front cam-
era to detect objects ( P.209)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to he lp the driver
avoid the collision. If the sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.

Driving
This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, d etermines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appe ars
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this ti me). The system will
respond to changes in the speed of the vehicle ahead in order t o maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also sto p (vehicle is stopped
by system control). After the vehicle ahead starts off, pressin g the “+RES” switch or
depressing the accelerator pedal (start-off operation) will res ume follow-up cruising.
If the start-off operation is not performed, system control con tinues to keep your
vehicle stopped.

(warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 30 cm (1.0 ft.)
before the display is shown and the warning buzzer sounds.• It might be difficult to hear the buzzer
due to the volume of the audio system or air flow noise of the air conditioning system.
• It may be difficult to hear the sound of this system due to the buzzers of other systems.
■Objects which the system may not
be properly detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro-
jecting outwards in the direction of your vehicle
■Situations in which the system may not operate properly
Certain vehicle conditions and the sur- rounding environment may affect the ability of a sensor to correctly detect
objects. Particular instances where this may occur are listed below.
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors will resolve this problem.)
●A sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen the sensor display may be displayed abnormally, or objects, such
as a wall, may not be detected.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
●Pedestrians that are hard to reflect
ultrasonic waves (ex. skirts with gath- ers or frills).
●When objects that are not perpendicu-lar to the ground, not perpendicular to the vehicle traveling direction,
uneven, or waving are in the detection range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle and a detected object
●If an object such as a vehicle, motor-cycle, bicycle or pedestrian cuts in front of the vehicle or runs out from
the side of the vehicle
●If the orientation of a sensor has been
changed due to a collision or other impact
●When equipment that may obstruct a sensor is installed, such as a towing eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier, or snow plow
●If the front of the vehicle is raised or lowered due to the carried load
