■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at least enough gasoline to make the
low fuel level warning light (
P.467)
go off. If there is only a small
amount of fuel, the hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.9 gal.
Hybrid system precautions
Take care when handling the hybrid system, as it is a high
voltage system (about 650 V at maximum) as well as contains
parts that become extremely hot when the hybrid system is
operating. Obey the warning labels attached to the vehicle.

2484-5. Using the driving support systems
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
If the message does not disappea r, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an e xtremely cold
environment
• When the front camera cannot d etect objects in front of the vehicle, such
as when driving in the dark, sno w, or fog, or when bright lights are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, th e radar may
judge the surrounding environment can not be properly recognize d. In that
case, “Pre-Collision System Unavailable See Owner' s Manual” is dis-
played.
When the temperature around the
front camera is out side of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight r eflected from the
surface of the sunshade may cause
the temperature of the front camera
to become exce ssively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera.
Close the hood, remove the sticker,
etc. to clear the obstruction.
When “Pre-Collisi on System Radar
In Self Calibration Unavailable See
Owner's Manual” is displayed.Check whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

Driving
●Initialization may not have been
performed after a battery terminal
was disconnected and recon-
nected. Initialize the system.
(  P.295) If this message contin-
ues to be displayed even after ini-
tialization, have the vehicle
inspected by you r Toyota dealer.
■If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed on the multi-informa-
tion display
A sensor may be covered with ice,
snow, dirt, etc. Remove the ice,
snow, dirt, etc., from the sensor to
return the syste m to normal.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
■If a 12-volt batte ry terminal has
been disconnected and recon-
nected
The system needs to be initialized.
To initialize the system, drive the
vehicle straight ahead for 5 seconds
or more at a speed of approximately
22 mph (35 km/h) or more.
■Sensor detection information
●The following situations may occur
during use.
• The sensor's detection areas are limited to the areas around the
vehicle front and rear bumpers.
• Depending on the shape of the object and other factors, the
detection distance may shorten, or
detection may be impossible.
• If an object is extremely close to a
sensor, it may not be detected.
• There will be a short delay
between object detection and dis-
play. Even at low speeds, there is
a possibility that the object will
come within the sensor’s detec-
tion areas before the display is
shown and the warning beep
sounds.
• It might be difficult to hear the buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be diffi cult to hear the
buzzer if buzzers for other sys-
tems are sounding.
■Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attent ion to the follow-
ing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Part icular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is froz en. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnormally,
or objects, such as a wall, may not
be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.

a guardrail, wall, sigh, or parked
vehicle, which may reflect electri-
cal waves toward the rear of the
vehicle, is short
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle carrier, or snow plow
●When a vehicle passes by the
side of your vehicle
●When a detected vehicle turns
while approaching the vehicle
●When there are spinning objects
near your vehicle such as the fan
of an air conditioning unit
●When water is splashed or
sprayed toward t he rear bumper,
such as from a sprinkler
●Moving objects (flags, exhaust
fumes, large rain droplets or
snowflakes, rain water on the road
surface, etc.)
●When the distanc e between your vehicle and a guardrail, wall, etc.,
that enters the detection area is
short
●Gratings and gutters
●When a sensor or the area around
a sensor is extremely hot or cold
●If the suspension has been modi-
fied or tires of a
size other than
specified are installed
●If the front of the v ehicle is raised
or lowered due to the carried load

When Sport mode is selected,
Sport mode indicator comes on.
3Eco drive mode
Helps the driver a ccelerate in an
eco-friendly manner and improve
fuel economy through moderate
throttle characteri stics and by con-
trolling the operation of the air con-
ditioning system (heating/cooling).
When Eco drive mode is selected,
Eco drive mode indicator comes
on.
■Air conditioning system opera-
tion in Eco drive mode
In Eco drive mode, heating/cooling
operations and the fan speed is con-
trolled to improve fuel efficiency.
Perform the following procedures to
increase the air conditioning perfor-
mance.
●Vehicle with a 12.3-inch display:
Turn eco air conditioning mode off
(  P.348)
●Adjust the fan speed ( P.341)
●Cancel Eco drive mode
■Canceling a driving mode
●Sport mode is automatically can-
celed and the driving mode
returns to normal mode when the
power switch is off.
●Normal mode and Eco drive mode
are not canceled until another
driving mode is sel ected. (Even if
the power switch is off, normal
mode and Eco drive mode will not
be automatically canceled.)
Press the Trail Mode switch
When the switch is pressed, Trail
Mode turns on and the Trail Mode
indicator illuminates on the
multi-information display.
When the switch is pressed again,
the Trail Mode indicator turns off.
Trail Mode (AWD mod-
els)
Trail Mode is a system that
performs integrated control
for the AWD, brake and
drive force control systems
to assist the drive power on
bumpy roads, etc.
WARNING
■Before using Trail Mode
Make sure to observe the follow-
ing precautions. Failure to
observe these precautions may
result in an unexp ected accident.
●Check that the Trail Mode indi-
cator is illuminated before driv-
ing. Trail Mode will not operate
when the indicator is off.
●Trail Mode is not intended to
expand the limits of the vehicle.
Thoroughly check the road con-
ditions and drive with caution.
●Thoroughly check the road con-
ditions before driving. As Trail
Mode is suitable for driving on
bumpy roads, there is a chance
that Trail Mode may not be the
most appropriate in terms of
other road conditions.
