WARNING
■When driving on slippery road surfaces
Do not accelerate or shift the shift lever suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to se t the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of t he brake pedal
when the shift lock override button is pressed and the shift le ver is shifted
out of P, the vehicle may suddenly start, possibly leading to a n accident
resulting in death or serious injury.
NOTICE
■ Hybrid battery (traction battery) charge
If the shift lever is in N, the hybrid battery (traction batter y) will not be
charged. To help prevent the battery from discharging, avoid le aving the N
position selected for an extended period of time.

Brake Hold
Turns the brake hold system on
The brake hold standby indicator
(green) comes on. While the sys-
tem is holding the brake, the brake
hold operated indicator (yellow)
comes on.
■ Brake hold system operating conditions
The brake hold system cannot be turned on in the following cond itions:
● The driver’s door is not closed.
● The driver is not wearing the seat belt.
If any of the conditions above are detected when the brake hold system is
enabled, the system will turn off and the brake hold standby in dicator light will
go off. In addition, if any of the conditions are detected whil e the system is
holding the brake, a warning buzzer will sound and a message wi ll be shown
on the multi-information display. The parking brake will then b e set automati-
cally.
The brake hold system keeps the brake applied when the shift
lever in D, S (M20A-FXS engine) or N with the system on and the
brake pedal has been depressed to stop the vehicle. The system
releases the brake when the accelerator pedal is depressed with
the shift lever in D or S (M20A-FXS engine) to allow smooth sta rt
off.

● On an extremely bumpy road, on an incline, on gravel, or on grass.
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
● A sensor is coated with a sheet of spray or heavy rain.
● If objects draw too close to the sensor.
● When a pedestrian is wearing clothing that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandstorm
● When an object that cannot be detected is between the vehicle and a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
● If the orientation of a sensor has been changed due to a collision or other
impact
● When equipment that may obstruct a sensor is installed, such as a towing
eyelet, bumper protector (an additional trim strip, etc.), bicy cle carrier, or
snow plow
● If the front of the vehicle is raised or lowered due to the carried load
● If the vehicle cannot be driven in a stable manner, such as when the vehicle
has been in an accident or is malfunctioning
● When a tire chains, compact spare tire or an emergency tire puncture repair
kit is used
● When a sensor or the area around a
sensor is extremely hot or cold.

■ Situations in which the system may operate even if there is no possibil-
ity of a collision
In some situations, such as the following, the system may opera te even
though there is no possibility of a collision.
● When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad crossings, toll gates and parki ng lots)
● When there is a rut or hole in the surface of the road
● When driving on a metal cover (grating), such as those used for drainage
ditches
● When driving up or down a steep slope
● If a sensor is hit by a large amount of water, such as when driving on a
flooded road
● There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
● A sensor is coated with a sheet of spray or heavy rain
● When driving in inclement weather such as fog, snow or a sandstorm
● When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of other vehicles or other devices which
produce ultrasonic waves are near the vehicle
● If the front of the vehicle is raised or lowered due to the carried load
● If the orientation of a sensor has been changed due to a collision or other
impact
● When driving on a narrow road
●When strong winds are blowing

■If the Parking Support Brake has operated
If the vehicle is stopped due to operation of the Parking Suppo rt Brake, the
Parking Support Brake will be disabled and the PKSB OFF indicat or will illu-
minate. If the Parking Support Brake operates unnecessarily, br ake control
can be canceled by depressing the brake pedal or waiting for ap proximately 2
seconds for it to automatically be canceled. Then, the vehicle can be oper-
ated by depressing the accelerator pedal.
■ Re-enabling the Parking Support Brake
To re-enable the Parking Support Brake when it has been disabled due to oper-
ation of the Parking Support Brake, either enable the system ag ain (P. 476),
or turn the engine switch off and then back to ON.
Additionally, if any of the following conditions are met, the s ystem will be re-
enabled automatically and the PKSB OFF indicator will turn off:
● The P shift position is selected
● The object is no longer detected in the traveling direction of the vehicle
● The traveling direction of the vehicle changes
■ If “Parking Support Brake Unavailable” and “Parking assist unavailable.
Clean parking assist sensor” is displayed on the multi-informat ion dis-
play and the PKSB OFF indicator is flashing
● A sensor may be covered with ice, snow, dirt, etc. Remove any ice, snow,
dirt, etc., from the sensor to return the system to normal.
If this message continues to be displayed even after cleaning t he sensor, or
is displayed even though the sensor is clean, have the vehicle inspected
any authorized Toyota retailer, Toyota authorized repairer, or any reliable
repairer.
● It is possible the sensor may be frozen.
Once the ice melts, the system will return to normal.
● Water may be continuously flowing over the surface of the sensor.
When the system judges there is no problem, the system will ret urn to nor-
mal.
■ If a 12-volt battery terminal has been disconnected and reconnected
The system needs to be initialized. To initialize the system, d rive the vehicle
straight ahead for 5 seconds or more at a speed of approximatel y 35 km/h
(22 mph) or more. Additionally, fo r vehicles with the Parking Support Brake
function, turn the steering wheel fully to the left and right w ith the vehicle
stopped.

lightly on the steering wheel without applying any force, direc tly
confirm the safety of the area to the rear and around the vehic le,
confirm that there are no obstacles in the parking space, and
slowly back up while adjusting your speed by depressing the
brake pedal.
● When backing up too quickly, a sharp beeping sound is emit-
ted and assist control is stopped. (P. 493)
● When the vehicle cannot be cleanly entered within the target
parking spot on the first try and multi-turn maneuvering is nec -
essary, proceed to step .
When multi-turn maneuvering is not necessary, proceed to
step .
When a level beep is emit-
ted and the stop display
(P. 493) is shown on the
display, stop the vehicle.
Change the shift lever to D, S (M20A-FXS engine) or B
(2ZR-FXE engine).

■Parking
Stop so that the center of the
target parking spot appears
nearly perpendicular to vehi-
cle. Then, press the S-IPA
switch 2 times and check that
the display on the multi-infor-
mation display switches to
“Back-in Parking”.
● Visually check the area in
the direction of the arrow
indicating the direction of
the steering wheel auto
operation and the target
parking spot on the dis-
play.
● The mode switches each
time the S-IPA switch is
pressed. (P. 492)
● When the shift lever is not in D, S (M20A-FXS engine) or B
(2ZR-FXE engine), or when the vehicle speed has been
detected, pressing the S-IPA switch will not cause the screen
to switch to the “Back-in Parking” display.
● The turn signal lever (P. 322) can be operated to select
whether you would like to park to the left or right.
● The system cannot be used when the parking space is narrow
or there is not a sufficient enough area for assist control to
operate. Please refer to the information shown on the multi-
information display to use a different parking space.
