Plug-in hybrid system
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. In the N, the gasoline
engine operates but electricity
cannot be generated. Also,
when using the air conditioning
system, etc., the hybrid battery
(traction battery) power is con-
sumed.
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes
gently and a timely manner. A greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
high fuel and electricity con-
sumption. Check traffic reports
before leaving and avoid delays
as much as possible. When driv-
ing in a traffic jam, gently
release the brake pedal to allow
the vehicle to move forward
slightly while avoiding overuse
of the accelerator pedal. Doing
so can help control excessive
electricity and fuel consumption.

Control and maintain the vehi-
cle at a constant speed.
Before stopping at a toll booth
or similar, allow plenty of time
to release the accelerator and
gently apply the brakes. A
greater amount of electrical
energy can be regenerated
when slowing down.
 Electricity consumption will
increase significantly when
driving at high speeds in EV
mode or AUTO EV/HV mode.
If there will be a long distance
to the next external charging
point after leaving a freeway,

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 brakes 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 that 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 shift 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 limits 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 apply 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 glasses, 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 vehicle’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.
