HV mode while on the free-
way and change to EV mode
or AUTO EV/HV mode after
leaving the freeway. (P.78)
 Turn the “A/C” switch off
when it is not needed. Doing
so can help reduce excessive
electricity and fuel consump-
tion.
In summer: When the ambient tem-
perature is high, use the recircu-
lated air mode. Doing so will help to
reduce the burden on the air condi-
tioning system and reduce electric-
ity and fuel consumption as well.
In winter: Avoid excessive and
unnecessary use o f the heater.
Usage of the heated steering wheel
(if equipped) ( P.407) and seat
heaters ( P.408) are effective.
 Using the Remote Air Condi-
tioning System ( P.405)
while the AC charging cable is
connected to the vehicle can
reduce electricity consump-
tion immediately after starting
off by operating air condition-
ing mainly using electricity
from an external power
source.
 When setting the charging
schedule, setting the charging
mode to “Departure” and “Cli-
mate Prep” to on can reduce
electricity consumption imme-
diately after starting off by
operating air conditioning before charging is completed.
(
P.130)
Make sure to check the tire infla-
tion pressure frequently. If there
is improper tire inflation pres-
sure in the tires, the EV driving
range will become shorter, and
fuel consumption when in HV
mode will increase.
Also, as snow tires can cause
large amounts of friction, their
use on dry roads can lead to
increased fuel and electricity
consumption.
Carrying heavy luggage will lead
to poor fuel economy. Avoid car-
rying unnecessary luggage.
Installing a large roof rack will
also cause poor fuel economy.
Since the gasoline engine starts
up and cuts out automatically,
warming up is not necessary.

Driving
WARNING
●During normal driving, do not
turn off the hybrid system. Turn-
ing the hybrid system off while
driving will not cause loss of
steering or braking control, how-
ever, power assist to the steer-
ing 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.505
●Use engine braking (downshift)
to maintain a safe speed when
driving down a steep hill.
Using the brakes continuously
may cause the br akes to over-
heat and lose effectiveness.
(  P.285)
●Do not adjust the position of the
steering wheel, the seat, or the
inside or outside rear view mir-
rors while driving.
Doing so may result in a loss of
vehicle control.
●Always check that all passen-
gers’ arms, head or other parts
of their body are not outside the
vehicle.
●Do not drive in excess of the
speed limit. Even if the legal
speed limit permits it, do not
drive over 85 mph (140 km/h)
unless your vehicle has high-
speed capability tires. Driving
over 85 mph (140 km/h) may
result in tire failure, loss of con-
trol and possible injury. Be sure
to consult a tire dealer to deter-
mine whether the tires on your
vehicle are high-speed capabil-
ity tires or not b efore driving at
such speeds.
■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
braking due to shifting, or
changes in engine speed could
cause the vehicle to skid.
●After driving through a puddle,
lightly depress the brake pedal
to make sure t hat the brakes
are functioning properly. Wet
brake pads may prevent the
brakes from functioning prop-
erly. If the brakes on only one
side are wet and not functioning
properly, steering control may
be affected.
■When shifting the shift lever
●Do not let the vehicle roll back-
ward while a fo rward driving
position is selected, or roll for-
ward while the shift lever is in R.
Doing so may result in an acci-
dent or damage to the vehicle.
●Do not shift the sh ift lever to P
while the vehicle is moving.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the sh ift lever to R
while the vehicle is moving for-
ward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.
●Do not shift the shift lever to a
driving position while the vehicle
is moving backward.
Doing so can damage the trans-
mission and may result in a loss
of vehicle control.

2625-1. Before driving
WARNING
●Moving the shift lever to N while
the vehicle is moving will disen-
gage the hybrid system. Engine
braking is not available with the
hybrid system disengaged.
●Be careful not to shift the shift
lever with the accelerator pedal
depressed.
Shifting the shift lever to a gear
other than P or N may lead to
unexpected rapid acceleration
of the vehicle that may cause an
accident and result in death or
serious injury. Doing so can
damage the transmission and
may result in a loss of vehicle
control.
■If you hear a squealing or
scraping noise (brake pad
wear limit indicators)
Have the brake pads checked and
replaced by your Toyota dealer as
soon as possible.
Rotor damage may result if the
pads are not replaced when
needed.
It is dangerous to drive the vehicle
when the wear lim its of the brake
pads and/or those of the brake
discs are exceeded.
■When the vehicle is stopped
●Do not depress t he accelerator
pedal unnecessarily.
If the vehicle is in any gear other
than P or N, the vehicle may
accelerate suddenly and unex-
pectedly, causing an accident.
●In order to prev ent accidents
due to the vehicle rolling away,
always keep depressing the
brake pedal while stopped with
the “READY” indicator is illumi-
nated, and appl y the parking
brake as necessary.
●If the vehicle is stopped on an
incline, in order to prevent acci-
dents caused by the vehicle roll-
ing forward or backward, always
depress the brake pedal and
securely apply the parking
brake as needed.
●Avoid revving or racing the
engine.
Running the engine at high
speed while the vehicle is
stopped may cause the exhaust
system to overheat, which could
result in a fire if combustible
material is nearby.
■When the vehicle is parked
●Do not leave gla sses, cigarette
lighters, spray cans, or soft
drink cans in the vehicle when it
is in the sun.
Doing so may result in the fol-
lowing:
• Gas may leak from a cigarette lighter or spray can, and may
lead to a fire.
• The temperature inside the vehicle may cause the plastic
lenses and plastic material of
glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray
over the interior of the vehicle,
and may also cause a short cir-
cuit in the vehicl e’s electrical
components.
●Do not leave cigarette lighters in
the vehicle. If a cigarette lighter
is in a place such as the glove
box or on the floor, it may be lit
accidentally when luggage is
loaded or the se at is adjusted,
causing a fire.

4Apply the parking brake
firmly.
5 Shift into P and turn off the
hybrid system.
 When restarting after parking
on a slope:
1 With the transmission in P,
start the hybrid system. Be
sure to keep the brake pedal
depressed.
2 Shift into a forward gear. If
reversing, shift into R.
3 If the parking brake is in man-
ual mode, release the park-
ing brake. ( P.290)
4 Release the brake pedal, and
slowly pull or back away from
the wheel blocks. Stop and
apply the brakes.
5 Have someone retrieve the
blocks.
■Break-in schedule
If your vehicle is new or equipped
with any new power train compo-
nents (such as an engine, transmis-
sion, differential or wheel bearing),
Toyota recommends that you do not
tow a trailer unt il the vehicle has
been driven for over 500 miles (800
km).
After the vehicle has been driven for
over 500 miles (800 km), you can
start towing. However, for the next
500 miles (800 km), drive the vehi-
cle at a speed of less than 45 mph
(72 km/h) when towing a trailer, and
avoid full throttle acceleration.
■Maintenance
●If you tow a traile r, your vehicle
will require more f requent mainte-
nance due to the additional load. (See “Scheduled Maintenance
Guide” or “Owner
’s Manual Sup-
plement”.)
●Retighten the fixing bolts of the
towing ball and bracket after
approximately 600 miles (1000
km) of tra iler towing.
■If trailer sway occurs
One or more factors (crosswinds,
passing vehicles, rough roads, etc.)
can adversely affect handling of
your vehicle and t railer, causing
instability.
●If trailer swaying occurs:
• Firmly grip the steering wheel. Steer straight ahead.
Do not try to contr ol trailer sway-
ing by turning the steering wheel.
• Begin releasing the accelerator
pedal immediately but very gradu-
ally to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and trailer should stabilize (if
enabled, Trailer Sway Control can
also help to stabilize the vehicle and
trailer.).
●After the trailer swaying has
stopped:
• Stop in a safe place. Get all occu-
pants out of the vehicle.
• Check the tires of the vehicle and the trailer.
• Check the load in the trailer. Make sure the load has not
shifted.
Make sure the tongue weight is
appropriate, if possible.
• Check the load in the vehicle.
Make sure the vehicle is not over-
loaded after occupants get in.
If you cannot find any problems, the
speed at which trailer swaying
occurred is beyond the limit of your
particular vehicle-trailer combina-
tion. Drive at a lower speed to pre-
vent instability. Remember that

cautions to minimize the risk of
death, serious injury or damage to
your vehicle:
●Drive carefully when off the
road. Do not take unnecessary
risks by driving in dangerous
places.
●Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel
and injure your hands. Keep
both hands and es pecially your
thumbs on the outside of the
rim.
●Always check your brakes for
effectiveness immediately after
driving in sand, mud, water or
snow.
●After driving thro ugh tall grass,
mud, rock, sand, rivers, etc.,
check that there is no grass,
bush, paper, rags, stone, sand,
etc. adhering or trapped on the
underbody. Clear off any such
matter from the u nderbody. If
the vehicle is used with these
materials trapped or adhering to
the underbody, a breakdown or
fire could occur.
●When driving off-road or in rug-
ged terrain, do not drive at
excessive speeds, jump, make
sharp turns, strike objects, etc.
This may cause loss of control
or vehicle rollover causing
death or serious injury. You are
also risking expensive damage
to your vehicle’s suspension
and chassis.
NOTICE
■To prevent the water damage
Take all necessar y safety mea-
sures to ensure that water dam-
age to the hybrid b attery (traction
battery), hybrid system or other
components does not occur.
●Water entering th e engine com-
partment may cause severe
damage to the hybrid system.
●Water entering the hybrid trans-
mission will cause deterioration
in transmission quality. The
malfunction indicator may come
on, and the vehicle may not be
drivable.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the hybrid
transaxle case, reducing the
gear oil’s lubricating qualities.
■When you drive through
water
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of t he riverbed for
firmness. Drive s lowly and avoid
deep water.
