WARNING
■If a safety system warning
light does not come on
Should a safety system light such
as the ABS and SRS warning light
not come on when you start the
EV system, this c ould mean that
these systems are not available to
help protect you in an accident,
which could result in death or seri-
ous injury. Have the vehicle
inspected by you r Toyota dealer
immediately if this occurs.

When the following unusual
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.

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.

position switch to change the
shift position to P.
 If the automatic P position
switching operation selection
function is performed oper-
ated with the EV system
stopped, the automatic P
position selection function
may not operate.
Always perform the operation
with the EV system started.
*: To keep this state, do not operate
the power switch. If the power
switch is operated repeatedly, the
power switch will turn off after the
shift position has automatically
changed to P.
■“X-MODE”
 P. 3 8 2
Acceleration/deceleration con-
trol can be performed only by
operating the accelerator pedal,
and the frequency of switching
to the brake pedal can be
greatly reduced. Since the
deceleration when the accelera-
tor pedal is released is stronger
than that of a conventional vehi-
cle, the vehicle can be deceler-
ated smoothly by slowly
releasing the pedal the acceler-
ator pedal without completely releasing it.
When the Regeneration Boost
switch is pressed, the regenera-
tive braking force, when the
accelerator pedal is released,
becomes stronger than usual.
■When Regeneration Boost can-
not be used In the following
cases, the system does not
operate.
●When “X-MODE” is activated (If
equipped)
●When the brake
system or EV
system is malfunctioning
●When regenerative braking is lim-
ited
Regenerative braking may be
restricted in the fo llowing situations:
• When the amount of charge of the traction battery is high
• When the temperature of the trac-
tion battery is low or extremely
high
• When the temperature of the elec-
tric motor or powe r control unit is
extremely high
• When regenerative braking is con- tinually used for a long time
■Regenerative Braking
●The vehicle cannot be stopped by
just releasing the accelerator
pedal. Step on the brake pedal
when the vehicle is stopped.
●If the power switch is turned off

Normal mode
Has a good balance of electrical
consumption performance, quiet-
ness, and driving performance, and
is suitable for driving in urban
areas.
2SNOW/DIRT mode
When the tires are likely to slip or
slip on slippery roads such as
snowy roads, gravel roads, etc., the
tire spinning is reduced, making it
easier to drive.
At this time, the SNOW/DIRT mode
indicator lights up in green on the
meter.
3 D.SNOW/MUD mode
In special cases such as the tires
being buried in de ep snow or mud,
the TRAC (Traction Control) func-
tion is temporarily canceled, and
the tires are idle d as needed to
make it easier to start.
At this time, the D.SNOW/MUD
mode indicator lights up in green on
the meter. In addition, the VSC OFF
indicator and PCS warning light will
be turned on in the meter.
WARNING
■Conditions in wh ich it may
not function correctly
When driving on the following
road surfaces, it may not be pos-
sible to maintain a constant speed

trolled Brake System)
The electronically controlled
system generates braking force
corresponding to the brake
operation
■ABS (Anti-lock Brake Sys-
tem)
Helps to prevent wheel lock
when the brakes are applied
suddenly, or if the brakes are
applied while driving on a slip-
pery road surface
■Brake assist
Generates an increased level of
braking force after the brake
pedal is depressed when the
system detects a panic stop sit-
uation
■VSC (Vehicle Stability Con-
trol)
Helps the driver to control skid-
ding when swerving suddenly or
turning on slippery road sur-
faces.
■Trailer Sway Control
Helps the driver to control trailer
sway by selectively applying
brake pressure for individual
wheels and reducing driving
torque when trailer sway is
detected.
■TRAC (Traction Control)
Helps to maintain drive power
and prevent the drive wheels
from spinning when starting the
vehicle or accelerating on slip-
pery roads
■Active Cornering Assist
(ACA)
Helps to prevent the vehicle
from drifting to the outer side by
performing inner wheel brake
control when attempting to
accelerate while turning
■Hill-start assist control
Helps to reduce the backward
movement of the vehicle when
starting on an uphill
■EPS (Electric Power Steer-
ing)
Employs an electric motor to
reduce the amount of effort
needed to turn the steering
wheel.
Driving assist systems
To keep driving safety and
performance, the following
systems operate automati-
cally in response to various
driving situations. Be
aware, however, that these
systems are supplementary
and should not be relied
upon too heavily when
operating the vehicle.

WARNING
●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 necessary safety mea-
sures to ensure that water dam-
age to the traction battery, EV
system or other components does
not occur.
●Water entering the motor com-
partment may cause severe
damage to the EV system.
●Water entering the transmis-
sion will cause deterioration in
transmission quality. The mal-
function indicator may come on,
and the vehicle may not be driv-
able.
●Water can wash the grease
from wheel bearings, causing
rusting and premature failure,
and may also enter the tran-
saxle 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 the riverbed for
firmness. Drive slowly and avoid
deep water.
■Inspection after off-road driv-
ing
●Sand and mud that has accu-
mulated around brake discs
may affect braking efficiency
and may damage brake system
components.
●Always perform a maintenance
inspection after each day of off-
road driving that has taken you
through rough terrain, sand,
mud, or water. For scheduled
maintenance information, refer
to the “Scheduled Maintenance
Guide” or “Owner’s Manual
Supplement”.
