on. (vehicles without a manual air
conditioning system)
• The windshield defogger is turned on.
(vehicles without a manual air condi-
tioning system)
• The shift lever is shifted from D to
except for P (When the engine is
stopped by the Stop & Start system
when the shift lever is in D.) (vehicles
with a Multidrive).
• The shift lever is shifted from P.
(When the engine is stopped by the
Stop & Start system when the shift
lever is in P.) (vehicles with a Multid-
rive)

• If the battery charge becomes low.
■When the hood is opened
●If the hood is opened while the engine
is stopped by the Stop & Start system,
the engine will stall and will not be
able to be restarted by the automatic
engine start function. In this case,
restart the engine using the normal

■Air conditioning system operation
while the engine is stopped by the
Stop & Start system
Vehicles with an automatic air condition-
ing system: When the air conditioning is
in automatic mode and the engine is
stopped by the Stop & Start system, the
fan may operate at a low speed in order
to prevent the temperature in the cabin
from increasing or decreasing or may be
stopped.
To prioritize air conditioning system per-
formance when the vehicle is stopped,
disable the Stop & Start system by
pressing the Stop & Start cancel switch.

system indicator will flash. To stop the
buzzer, close the driver’s door.
■The Stop & Start system protection
function
●When the volume of the audio system
is excessively high, sound output from
the audio system may suddenly be cut
off in order to reduce battery con-
sumption. To prevent the audio sys-
tem from being cut off, keep the
volume of audio system at a moderate
level. If the audio system has been cut
off, turn the engine switch off, wait for
3 seconds or more and then turn it to
ACC or ON to re-enable the audio
system.
●The audio system may not be acti-
vated if the battery terminals are dis-
connected and then reconnected. If
this occurs, turn the engine switch off
and then repeat the following opera-
tion twice to activate the audio system
normally.
• Turn the engine switch to ON and
then to off.

Driving
●There will be a short delay between
object detection and display. Even at low speeds, there is a possibility that the object will come within the sen-
sor’s detection areas before the dis- play 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 difficult to hear the buzzer if buzzers for other systems are sound-ing.
■Conditions under which the func-
tion may not function correctly
Certain vehicle conditions and the sur- rounding environment may affect the
ability of a sensor to correctly detect objects. Particular 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 frozen. (Thawing the area
will resolve this problem.) In especially cold weather, if a sensor is frozen the sensor display may be
displayed abnormally, or objects, such as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a
sensor is extremely hot or cold.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●The vicinity of the vehicle is noisy due
to vehicle horns, motorcycle engines, air brakes of large vehicles, or other loud noises producing ultrasonic
waves.
●There is another vehicle equipped
with parking assist sensors in the vicinity.
●A sensor is coated with a sheet of spray or heavy rain.
●If a sensor is hit by a large amount of water, such as when driving on a
flooded road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly detected
The shape of the object may prevent the
sensor from detecting it. Pay particular attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro- jecting outwards in the direction of your vehicle
People may not be detected if they are wearing certain types of clothing.
■Detection range of the sensors
Approximately 100 cm (3.3 ft.)

●When there are spinning objects near
your vehicle such as the fans of an air conditioning unit
●When water is splashed or sprayed toward the rear bumper, such as from a sprinkler
■Situations in which the Parking
Support Brake function (rear-cross- ing vehicles) may not operate prop-erly
In some situations, such as the follow- ing, the radar sensors may not detect an object and this function may not operate
properly
●Stationary objects
●When a sensor or the area around a sensor is extremely hot or cold
●If the rear bumper is covered with ice, snow, dirt, etc.
●When it is raining heavily or water strikes the vehicle
●When the detection area of a radar sensor is obstructed by an adjacent
vehicle
●If the vehicle is significantly tilted
●When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an addi- tional trim strip, etc.), bicycle carrier, or snow plow
●If the suspension has been modified or tires of a size other than specified
are installed
●If the front of the vehicle is raised or
lowered due to the carried load
●If an electronic component, such as a
backlit license plate (especially fluo- rescent type), fog lights, fender pole
or wireless antenna is installed near a
radar sensor
●If the orientation of a radar sensor has
been changed
●When multiple vehicles are approach-
ing with only a small gap between each vehicle
●If a vehicle is approaching the rear of your vehicle rapidly
●Situations in which the radar sensor may not detect a vehicle• When a vehicle approaches from the
right or left at the rear of the vehicle while you are turning while backing up• When turning while backing up
• When backing out of a shallow angle parking spot
• When backing up on a slope with a sharp change in grade

teristics and by controlling the operation
of the air conditioning system (heat-
ing/cooling).
When the Eco drive mode is selected,
Eco drive mode indicator comes on.
■Operation of the air conditioning
system in Eco drive mode
Eco drive mode controls the heat-
ing/cooling operations and fan speed of
the air conditioning system to enhance
fuel efficiency. To improve air condition-
ing performance, perform the following
operations:
●Turn off air conditioning eco mode
(vehicles with an automatic air condi-
tioning system) (→P.285)
●Adjust the fan speed (→P.279, 284)
●Turn off Eco drive mode
■Automatic deactivation of power
mode
If the engine switch is turned off after
driving in power mode, the drive mode
will be changed to normal mode.
*: If equipped
■If “Exhaust Filter Full See Owner’s
Manual” is shown on the multi-
information display
●The message may be displayed while
high load driving with particulate mat-
ter accumulating.
●Engine output is restricted while the
message is displayed, however, it is
possible to drive the vehicle unless
the malfunction indicator lamp comes
on.
●Particulate matter can accumulate
more quickly if the vehicle is fre-
quently driven short trips or at low
speeds, or if the engine is regularly
started in an extremely cold environ-
ment. Excessive accumulation of par-
ticulate matter can be prevented by
periodically driving long distances
continuously with intermittent releas-
ing of the accelerator pedal, such as
when driving on highways and free-
ways.
■If the malfunction indicator lamp
comes on or “Engine Maintenance
Required Visit Your Dealer” is
shown on the multi-information
display
The amount of accumulated particulate
matter has exceeded a certain level.
Have the vehicle inspected by any
authorized Toyota retailer or Toyota
GPF (Gasoline Particu-
late Filter) system
*
The GPF system collects par-
ticulate matter in the exhaust
gas by using an exhaust gas
filter.
The system will operate to
regenerate the filter automati-
cally, depending on the vehicle
conditions.
