WARNING
●During normal driving, do not
turn off the EV system. Turning
the EV system off while driving
will not cause loss of steering or
braking 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. 5 0 5
●Use regenerative braking 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.240)
●If “Regenerative braking lim-
ited. Press brake to decelerate.”
appears on the multi-informa-
tion display, firmly depress the
brake pedal to decelerate the
vehicle. ( P.522)
●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, heads or other parts
of their body are not outside the
vehicle.
●AWD models: Do not drive the
vehicle off-road.
This is not a AWD vehicle
designed for off-road driving.
Proceed with all due caution if it
becomes unavoidable to drive
off-road.
●Do not drive across a river or
through other bodies of water.
This may cause electric/elec-
tronic components to short cir-
cuit, damage the EV system or
cause other serious damage to
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 fa ilure, 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 before 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 or regen-
erative braking due to shift
changing could cause the vehi-
cle to skid, resulting in an acci-
dent.
●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.

NOTICE
■When driving the vehicle
●Do not depress t he accelerator
and brake pedals at the same
time during drivin g, as this may
restrain the EV system output.
●Do not use the accelerator
pedal or depress the accelera-
tor and brake pedals at the
same time to hold the vehicle on
a hill.
■Avoiding damage to vehicle
parts
●Do not turn the steering wheel
fully in either direction and hold
it there for an extended period
of time.
Doing so may damage the
power steering motor.
●When driving over bumps in the
road, drive as slowly as possible
to avoid damagi ng the wheels,
underside of the vehicle, etc.
■If you get a flat tire while driv-
ing
A flat or damaged tire may cause
the following situations. Hold the
steering wheel firmly and gradu-
ally depress the brake pedal to
slow down the vehicle.
●It may be difficult to control your
vehicle.
●The vehicle will make abnormal
sounds or vibrations.
●The vehicle will lean abnor-
mally.
Information on what to do in case
of a flat tire ( P.527)
■When encountering flooded
roads
Do not drive on a road that has
flooded after heavy rain, etc.
Doing so may cause the following
serious damage to the vehicle:
●Short in electrical components
●Traction battery caused by
water immersion
In the event that you drive on a
flooded road and the vehicle is
flooded, be sure to have your Toy-
ota dealer check the following:
●Brake function
●Changes in quantity and quality
of transmission fluid, etc.
●Lubricant condition for the bear-
ings and suspension joints
(where possible), and the func-
tion of all joints, bearings, etc.
●Components connected to the
traction battery.
If the shift control system is dam-
aged by flooding, it may not be
possible to shift the shift position
to P, or from P to other positions.
In this case, contact your Toyota
dealer.
■When parking the vehicle
Always set the parking brake, and
shift the shift position to P. Failure
to do so may cause the vehicle to
move or the vehicle may acceler-
ate suddenly if t he accelerator
pedal is accidentally depressed.
■When involved in a minor
accident
Damage to the traction battery or
battery peripheral components
could cause malfunctions. Even if
it is a minor accident, have the
vehicle inspected by your Toyota
dealer.

WARNING
■Stopping the EV system in an
emergency
●If you want to stop the EV sys-
tem in an emergency while driv-
ing the vehicle, press and hold
the power switch for more than
2 seconds, or press it briefly 3
times or more in succession.
( P.505)
However, do not touch the
power switch while driving
except in an emergency. Turn-
ing the EV system off while driv-
ing will not cause a loss of
steering or braking control.
However, power assist for the
steering wheel may be lost mak-
ing it difficult to steer smoothly
before stopping the vehicle
depending on the remaining
charge in the 12-volt battery or
usage conditions. In this situa-
tion, you should pull over and
stop the vehicle as soon as it is
safe to do so.
●If the power switch is operated
while the vehicle is running, a
warning message will be shown
on the multi-info rmation display
and a buzzer sounds.
●When restarting the EV system
after an emergency shutdown,
press the power switch shortly
and firmly.
■When parking
Exhaust gases include harmful
carbon monoxide (CO), which is
colorless and odorless. Observe
the following precautions.
Failure to do so may cause
exhaust gases to enter the vehicle
and may lead to an accident
caused by light-headedness, or
may lead to death or a serious
health hazard.
●If the vehicle is in a poorly venti-
lated area or a closed area,
such as a garage, stop the EV
system.
●Do not leave the vehicle with
the EV system operating for a
long time. If such a situation
cannot be avoided, park the
vehicle in an open space and
ensure that exhaust fumes do
not enter the vehicle interior.
●Do not leave the EV system
operating in an area with snow
build-up, or where it is snowing.
If snowbanks build up around
the vehicle while the EV system
is operating, exhaust gases
may collect and enter the vehi-
cle.

Operation of this system is sep-
arated into 4 control states.
Through control state “warning
phase 1” and “warning phase 2”,
the system determines if the
driver is aware and responsive
while outputting a warning and
controlling the vehicle speed. If
the system determines the
driver is not responsive, it will
operate in control state “deceler-
ation stop phase” and “stop hold
phase” and decelerate and stop
the vehicle. It will then operate
continuously in “stop hold
phase”.
■Operating conditions
This system operates when all of
the following conditions are met:
●When the LTA is on
●When the vehicle speed is
approximately 30 mph (50 km/h)
or more

tions
In the following si tuations, system
operation will be canceled:
●When LTA control has been can-
celed (the LTA switch has been
pressed, etc.)
●When the dynamic radar cruise
control has been canceled
●When driver operations are
detected (the steering wheel is
held, the brake pedal, accelerator
pedal, parking brake, hazard light
switch, or turn signal lever is oper-

steering wheel, are not per-
WARNING
●After this system operates, pas-
sengers should attend to the
driver as necessary and take
appropriate hazard prevention
measures, such as moving to a
place where safety can be
ensured, such as the shoulder
of the road or b ehind a guard-
rail.
●This system detects the condi-
tion of the driver through the
operation of the steering wheel.
This system may operate if the
driver is aware but intentionally
and continuously does not oper-
ate the vehicle. Also, the system
may not operate if it cannot
determine that the driver is not
responsive, such as if they are
