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,

■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.

■When the ambient temperature
is low, such as during winter
driving conditions
●When starting the EV system, the
flashing time of the “READY” indi-
cator may be long. Leave the
vehicle as it is until the “READY”
indicator is steady on, as steady
means the vehicle is able to move.
●When the traction battery is
extremely cold (below approxi-
mately -22°F [-30°C]) under the
influence of the outside tempera-
ture, it may not be possible to start
the EV system. In this case, try to
start the EV system again after the
temperature of the traction battery
increases due to the outside tem-
perature increase, etc.

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.

●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

WARNING
■For the rotary shifter
●Do not remove the rotary shifter
knob or use anything but a gen-
uine Toyota rotary shifter knob.
Also, do not hang anything on
the rotary shifter.
Doing so could prevent the
rotary shifter from returning to

●In order to prevent the shift
position from accidentally being
changed, do not touch the
rotary shifter when not using it.
■P position switch
●Do not press the P position
switch while the vehicle is mov-
ing.
If the P position switch is
pressed when driving at very
low speeds (for example,
directly before stopping the

switches to P, which could lead
to an accident.
●In order to prevent the shift
position from accidentally being
changed, do not touch the P
position switch when not using
it.

■“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
