■Cautions regarding the use of
the system
Do not overly rely on the system, as
doing so may lead to an accident.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your
surroundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity
of collisions. However, it may not operate in some situations.
●The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the
system has stopped the vehicle, it is necessary to depress the brake
pedal immediately as brake control
will be canceled after approximately 2 seconds.
●It is extremely dangerous to check the system operatio ns by intention-
ally driving the vehicle into the
direction of a wall, etc. Never attempt such actions.
■When to disable the Parking Sup-port Brake
In the following situations, disable the
Parking Support Br ake as the system may operate even though there is no
possibility of a collision.
●When inspecting the vehicle using
a chassis roller, chassis dynamo or
free roller
●When loading the vehicle onto a
boat, truck or other transport vessel
●If the suspension has been modi-
fied 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
●When equipment that may obstruct a sensor is installed, such as a tow-
ing eyelet, bumper protector (an
additional trim strip, etc.), bicycle carrier, or snow plow
●When using automatic car washing devices
●If the vehicle cannot be driven in a stable manner, such as when the
vehicle has been in an accident or
is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn
●When a tire chains, compact spare
tire or an emergency tire puncture
repair kit is used
NOTICE
■If “Parking Support Brake Una- vailable” is displayed on the
multi-information display and the
PKSB OFF indicator is flashing
If this message is displayed immedi-
ately after the engine switch is
changed to ON, operate the vehicle carefully, paying attention to your
surroundings. It may be necessary to
drive the vehicle for a certain amount of time before the system returns to
normal. (If the system does not return
to normal after driving for a while, clean the sensors and their surround-
ing area on the bumpers.)

■Function summary
The Simple Inte lligent Parking
Assist System automatically oper-
ates the steering wheel to provide
support when backing into an area
near a target parking spot, and
when departing from a parallel
parking spot. (Shift lever operations
and speed adjustment when mov-
ing forward or backing up are not
performed automatically.)
 The Simple Intelligent Parking
Assist System does not park the
vehicle automatically. It is a sys-
tem that provides support when
pulling out of a perpendicular or
parallel parking spot.
 The Simple Intelligent Parking
Assist System provides steering
wheel operation assistance to
guide the vehicle toward the
selected intended parking spot.
The selected intended parking
spot may not always be reacha-
ble, depending on road and vehi-
cle conditions at the time of
parking, and the distance to the
intended parking spot.
■Linking with the PKSB (Park-
ing Support Brake) system (if
equipped)
While the Simple Intelligent Parking
Assist System is operating, if the
system detects an obstacle that
could result in a collision, the emer-
gency brakes operate, regardless
of whether the PKSB (Parking Sup-
port Brake) system is on or off.

■When using the Simple Intelli-
gent Parking Assist System
●When backing up or proceeding for- ward, be sure to directly confirm the
safety of the area to the front or
rear, and the area around the vehi- cle, and slowly back up or proceed
forward while adjusting the vehicle
speed by depressing the brake pedal.
●If it seems the vehicle may make contact with a pedestrian, another
vehicle or any other obstacles, stop
the vehicle by depressing the brake pedal, and then press the S-IPA
switch ( P.331) to turn the system
off.

●When Active Cornering Assist fre-
quently operates, Active Cornering
Assist may temporarily stop operat- ing to ensure proper operation of
the brakes, TRC and VSC.
■Hill-start assist control does not
operate effectively when
●Do not overly rely on hill-start assist
control. Hill-start assist control may not operate effectively on steep
inclines and roads covered with ice.
●Unlike the parking brake, hill-start
assist control is not intended to hold
the vehicle stationary for an extended period of time. Do not
attempt to use hill-start assist con-
trol to hold the vehicle on an incline, as doing so may lead to an acci-
dent.
■When the TRC/VSC/Trailer Sway
Control is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular
care when the indicator light flashes.
■When the TRC/VSC/Trailer Sway
Control systems are turned off
Be especially careful and drive at a
speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driv-
ing force, do not turn the
TRC/VSC/Trailer Sway Control sys- tems off unless necessary.
Trailer Sway Control is part of the
VSC system and will not operate if VSC is turned off or experiences a
malfunction.
■Replacing tires
Make sure that all tires are of the
specified size, brand, tread pattern
and total load capacity. In addition, make sure that the tires are inflated to
the recommended tire inflation pres-
sure level. The ABS, TRC Trailer Sway Control
and VSC systems w ill not function
correctly if different tires are installed on the vehicle.
Contact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer for further information
when replacing tires or wheels.
■Handling of tires and the suspen-
sion
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may
cause a system to malfunction.
■Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all
situations. Depending on many fac-
tors such as the conditions of the vehicle, trailer, road surface and driv-
ing environment, the Trailer Sway
Control system may not be effective. Refer to your trailer owner's manual
for information on how to tow your
trailer properly.
■If trailer sway occurs
Observe the following precautions. Failing to do so may cause death or
serious injury.
●Firmly grip the steering wheel.
Steer straight ahead. Do not try to
control trailer sway by turning the
steering wheel.
●Begin releasing the accelerator
pedal immediately but very gradu- ally to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.

when putting items in the open tray. Failure to do so may cause items to
be thrown out of the tray in the event
of sudden braking or steering. In these cases, the items may interfere
with pedal operation or cause driver
distraction, resulting in an accident.
●Do not store items in the tray that
can easily shift or roll out.
●Do not stack items in the tray higher
than the tray’s edge.
