display, read the message and fol-
low the instructions.
●If the door is unlocked with the
mechanical key, the EV system
cannot be started using the smart
key system. Refer to P.540 to start
the EV system. However, if the
electronic key is carried inside the
vehicle and the do
ors are locked
(  P.170), the EV system can be
started.
■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.
■Sounds and vibrations specific
to an battery electric vehicle
 P. 7 4
■If the 12-volt battery is dis-
charged
The EV system cannot be started
using the smart key system. Refer
to P.541 to restart the EV system.
■Electronic key battery depletion

■Note for the entry function
 P. 1 8 9
■If there is a malfunction in the
smart key system
If “Smart Key System Malfunction”
is displayed on the multi-information
display, the system may be malfunc-
tioning. Have the vehicle inspected
by your Toyota dealer immediately.
■If the “READY” indicator does
not come on
In the event that the “READY” indi-
cator does not come on even after
performing the proper procedures
for starting the vehicle, contact your
Toyota dealer immediately.

and firmly, the power switch mode
may not change or the EV system
may not start.
●If attempting to restart the EV sys-
tem immediately after turning the
power switch to OFF, the EV sys-
tem may not start in some cases.
After turning the power switch to
OFF, please wait a few seconds
before restarti ng the EV system.
■Customization
If the smart key system has been
deactivated in a customized setting,
refer to P.540.
WARNING

■Situations in which the sensors
may not operate properly
●When the height or inclination of
the vehicle has been changed due
to modifications
●When the windshield is dirty,
fogged up, cracked or damaged
●When the ambient temperature is
high or low
●When mud, water, snow, dead
insects, foreign matter, etc., is
attached to the fr ont of the sensor
●When in inclement weather such
as heavy rain, fog, snow, or a
sandstorm
●When water, snow, dust, etc. is
thrown up in front of the vehicle, or
when driving through mist or
smoke
●When the headlig hts are not illu-
minated while driving in the dark,
such as at night o r when in a tun-
nel
●When the lens of a headlight is
dirty and illumination is weak
●When the headlights are mis-
aligned
●When a headlight is malfunction-
ing
●When a the headlights of another vehicle, sunlight, or reflected light
shines directly into the front cam-
era
●When the brightness of the sur-
rounding area changes suddenly
●When driving near a TV tower,
broadcasting station, electric
power plant, radar equipped vehi-
cles, etc., or other location where
strong radio waves or electrical
noise may be present
●When a wiper blade is blocking
the front camera
●When in a location or near objects
which strongly reflect radio waves,
such as the following:
• Tunnels
• Truss bridges
• Gravel roads
• Rutted, snow-covered roads
• Walls
• Large trucks
• Manhole covers
• Guardrail
• Metal plates
●When near a step or protrusion

●When a detectable vehicle has
extremely high ground clearance
WARNING
●Do not modify or change the

■Front camera installation area
on the windshield
If the system determines that the
windshield may be fogged up, it
will automatically operate the
heater to defog the part of the
windshield around the front cam-
era. When cleaning, etc., be care-
ful not to touch the area around
the front camera until the wind-
shield has cooled sufficiently, as
touching it may cause burns.

WARNING
●Depending on the condition of
the road surface or the vehicle,
the distance between the vehi-
cle and a parking space, etc., it
may not be possible to detect a
parking space or the system
may not be able to provide
assistance to the point the vehi-
cle is fully parked.
●This system will guide the vehi-
cle to appropriate positions for
changing the direction of travel,
however, if you feel that the
vehicle is approaching too close
to an adjacent parked vehicle at
any time, depress the brake
pedal and change the shift posi-
tion. However, if this is per-
formed, the number of times the
vehicle changes direction may
increase, and the vehicle may
be parked at an angle.
●As following objects may not be
detected, make sure to check
the safety of the area around
your vehicle and depress the
brake pedal to stop the vehicle if
it may collide with an object.
• Thin objects such as wire, fences, rope, etc.
• Cotton, snow and other materi- als that absorb sound waves
• Sharply-angled objects
• Low objects (curb stones, park- ing blocks, etc.)
• Tall objects with upper sections that protrude outward
●Even if there is an object in the
target parking space, it may not
be detected and assistance
may be performed.
●While the system is operating, if
it is likely that your vehicle will
collide with a nearby vehicle,
parking block, object, or person,
depress the brake pedal to stop
the vehicle and press the
Advanced Park main switch to
disable the system.
●Never use only the multimedia
display to view the area behind
the vehicle. The image dis-
played may dif fer than the
actual situation. Using only the
screen when backing up may
lead to an accident, such as a
collision with another vehicle.
When backing up, make sure to
look directly or use the mirrors
to check the safe ty of the area
around your vehicle, especially
behind the vehicle.
●When the ambient temperature
is extremely low, the screen
may appear dark or the dis-
played image may become
unclear. Also, as moving objects
may appear distorted or may
not be able to be seen on the
screen, make sure to directly
check the safety of the area
around your vehicle.
In the following situations, while
the vehicle is stopped and held
by Advanced Park, it may be
canceled and th e vehicle may
start moving. Immediately
depress the brake pedal. Fail-
ure to do so may lead to an
accident.
• When the driver’s door is opened
• When operations instructed by the system are not performed
within a certain amount of time
• When the brake pedal is depressed and th e vehicle is
stopped for a certain amount of
time

ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■To prevent burns
●Do not touch the rear view mir-
ror surfaces when the outside
rear view mirror defoggers are
on.
●Vehicles with windshield wiper
de-icer: Do not touch the glass
at lower part of the windshield
or to the side of the front pillars
when the windshield wiper de-
icer is on.
