■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. 99)
●The emergency flashers will turn on automatically. (P. 664)
●For Safety Connect subscribers, if any of the following situations occur, the
system is designed to send an emergency call to the response center, noti-
fying them of the vehicle’s location (without needing to push the “SOS” but-
ton) 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 automatically treats the call as an emergency and

• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
■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 approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
situations:
• 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 underride collision, such as a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a
truck
●Depending on the type of collision, it is possible that only the seat belt pre-
tensioners and seat cushion airbag will activate.
●The SRS front airbags for the front passenger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied.
●The SRS seat cushion airbag on the front passenger seat will not operate if
the occupant is not wearing a seat belt.

Some information will be displayed automatically according to power
switch operation, vehicle condition, etc.
■When starting the hybrid system
When the hybrid system starts,
an opening animation is dis-
played on the main display.
After the animation ends, the
screens switch to the normal
screen.
The opening animation will be
stopped in any of the following
situations.
• When the shift position is changed to other than P
• When the Simple Advanced Parking Guidance System (if equipped)
is turned on
■
When the driving assist systems are operating
When using driving assist systems such as the dynamic radar
cruise control with full-speed range (P. 414) and LTA (Lane Trac-
ing Assist) (P. 395), information related to each system is auto-
matically displayed on the multi-information display depending on
the situation.
For details regarding the displayed information and the contents of the
display, refer to the explanation page of each system.
■
When there is information to be notified about the vehicle
When a shift position is mistakenly selected or a problem occurs in
a vehicle system, a warning message (or image) is displayed on
the multi-information display.
When a warning message is displayed, follow the instructions displayed
on the display. (P. 684)

Driving
Stop the vehicle completely.
Set the parking brake. (P. 3 5 2 )
Shift the shift position to P. (P. 346)
Check that the shift position indicator shows P.
Press the power switch to stop the hybrid system.
Slowly release the brake pedal.
Lock the door, making sure that you have the electronic key on your
person.
If parking on a hill, block the wheels as needed.
Firmly set the parking brake with the brake pedal depressed, and
then shift the shift position to D.
Release the brake pedal and gently depress the accelerator pedal.
Release the parking brake.
■When starting off on an uphill
The hill-start assist control will activate. (P. 502)
■For electricity-saving and fuel-efficient driving
Understand the system characteristics of the vehicle to use the functions of
the hybrid system. Also, keep in mind that hybrid vehicles are similar to con-
ventional vehicles, and it is necessary to refrain from activities such as sud-
den acceleration. Refer to “Plug-in hybrid vehicle driving tips” (P. 105).
■Driving in the rain
●Drive carefully when it is raining, because visibility will be reduced, the win-
dows may become fogged-up, and the road will be slippery.
●Drive carefully when it starts to rain, because the road surface will be espe-
cially slippery.
●Refrain from high speeds when driving 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.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle 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 assist function does not operate, do not fol-
low other vehicles closely and avoid downhill 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.
