■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from S RS airbags,
due to the extremely high speed deployment (inflation) by hot g ases.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover an d 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 h ot.
● The windshield may crack.
● The hybrid system will be stopped and fuel supply to the engine will be
stopped. ( P. 97)
● 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 t he “SOS” but-
ton) and an agent will attempt to speak with the occupants to a scertain the
level of emergency and assistance required. If the occupants are unable to
communicate, the agent automatically treats the call as an emer gency and
helps to dispatch the necessary emergency services. ( P. 75)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
■ SRS airbag deployment condi tions (SRS front airbags)
● The SRS front airbags will deploy in the event of an impact tha t exceeds the
set threshold level (the level of force corresponding to an app roximately 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 th e 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.

◆“Fuel Consumption Record”
When the unit is set to “MPH”
The transitions of the average fu el consumption after the hybrid
system starts can be checked in units of 1 mile (1.6 km) or 5 m iles
(8 km) of driving.
When the unit is set to “km/h”
The transitions of the average fu el consumption after the hybrid
system starts can be checked in units of 1 km (0.6 mile) or 5 k m
(3.1 miles) of driving.
■How to read the screen
The “ 1 miles” display is shown as an example. However, the
basic method for how to read the screen is the same for each fu el
consumption hi story screen.

5-4. Refueling
Opening the fuel tank cap
●Turn the power switch off and ensure that all the doors and win -
dows are closed.
● Confirm the type of fuel.
■Fuel types
P. 725
■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
The fuel tank of your vehicle h as a special structure, which
requires a reduction in fuel tank pressure before refueling. After
the opener switch has been pressed, it will take several second s
until the vehicle is r eady for refueling.

Driving
■Tire chain installation
Observe the following precautions when installing and removing chains:
● Install and remove tire chains in a safe location.
● Install tire chains on the front tires only. Do not install tir e chains on the rear
tires.
● Install tire chains on front tires as tightly as possible. Reti ghten chains after
driving 1/4 - 1/2 mile (0.5 - 1.0 km).
● Install tire chains following the instructions provided with th e tire chains.
■ Consumption of fuel and electricity
In cold temperatures, resistance of the parts of a vehicle (tra nsmission, tires,
etc.) generally increases, resulting in increase of energy cons umption. As a
result, fuel economy is likely to decrease.
Consumption of fuel and electricity of this vehicle is also lik ely to become
worse in cold temperatures.
WARNING
■ Driving with snow tires
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in a loss of vehicle control and ca use death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
■ Driving with tire chains
Observe the following precautions to reduce the risk of acciden ts.
Failure to do so may result in the vehicle being unable to be d riven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tir e chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that v ehicle con-
trol is maintained.
● Do not use LDA (Lane Departure Alert with steering control).
■ When parking the vehicle
When parking the vehicle without applying the parking brake, ma ke sure to
chock the wheels. If you do not chock the wheels, the vehicle m ay move
unexpectedly, possibly resulting in an accident.

7-1. Maintenance and care
■Caring for leather areas
Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle’s interior.
■ Shampooing the carpets
There are several commercial foaming-type cleaners available. U se a sponge
or brush to apply the foam. Rub in overlapping circles. Do not use water.
Wipe dirty surfaces and let them dry. Excellent results are obt ained by keep-
ing the carpet as dry as possible.
■ Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge . Also
check the belts periodically for excessive wear, fraying or cut s.
■ Cleaning the air intake vents and filters
●Dust on the air intake vents or filters may interferes cooling of the hybrid bat-
tery (traction battery) and results in poor electricity and fue l consumption.
Clean the air intake vents and filters periodically.
● If continuing to drive the vehicle with “Maintenance required f or Traction bat-
tery cooling parts See owner’s manual” shown on the multi-infor mation dis-
play, the hybrid battery (traction battery) may overheat, leadi ng to
decreasing in distance that can be driven using the electric mo tor. It may
cause poor electricity and fuel consumption or a malfunction. If the warning
message is shown, clean the air intake vents and filters immediately.
● Improper handling may result in damage to the grille or filters. If you have
any concerns about cleaning the filters, contact your Toyota dealer.
● If the warning message on the multi-information display does not disappear
after cleaning the filters, have the vehicle inspected by your Toyota dealer.
● Timing of cleaning filters differs depending on the use environ ment of the
vehicle.

When trouble arises
8-2. Steps to take in an emergency
If the hybrid system will not start
One of the following may be the cause of the problem:
● The charging cable may be a ttached to the vehicle. (P. 143)
● The electronic key may no t be functioning properly.
* ( P. 697)
● There may not be sufficient f uel in the vehicle’s tank.
Refuel the vehicle. ( P. 98)
● There may be a malfunction in the immobilizer system.
* ( P. 8 1 )
● There may be a malfunction i n the shift control system.
*
(  P. 335, 676)
● The hybrid system may be malfunc tioning due to an electrical prob-
lem such as electronic key battery depletion or a blown fuse. H ow-
ever, depending on the type of malfunction, an interim measure is
available to start the hybrid system. ( P. 696)
● There is a possibility that the t emperature of the hybrid battery
(traction battery) is extremely low (approximately below -22°F
[-30°C]). ( P. 98, 334)
*: It may not be possible to shift the shift position other than P.
One of the following may be the cause of the problem:
● The 12-volt battery may be discharged. ( P. 701)
● The 12-volt battery terminal connections may be loose or corrod ed.
(  P. 593)
Reasons for the hybrid system not starting vary depending on
the situation. Check the followi ng and perform the appropriate
procedure:
The hybrid system will not start even though the correct starting
procedure is being followed. ( P. 332)
The interior lights and headlights are dim, or the horn does no t
sound or sounds at a low volume.
