PKSB (Parking Sup-

port Brake)

The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.

WARNING

■

Cautions regarding the use of

the system

Do not overly rely on the system,

as doing so may lead to an acci-

dent.
Always drive while checking the

safety of the surroundings of the

vehicle.
Depending on the vehicle and

road conditions, weather, etc., the

system may not operate.
The detection capabilities of sen-

sors and radars are limited.

Always drive while checking the

safety of the surroundings of the

vehicle.

●

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 provide support to

lessen the severity of collisions.

However, it may not operate in

some situations.

●

The Parking Support Brake sys-

tem 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 imme-

diately as brake control will be

canceled after approximately 2

seconds.

●

It is extremely dangerous to

check the system operations by

intentionally driving the vehicle

into the direction of a wall, etc.

Never attempt such actions.

■

When to disable the Parking

Support Brake

In the following situations, disable

the Parking Support Brake as the

system may operate even though

there is no possibility of a colli-

sion.

●

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

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

●

When equipment that may

obstruct a sensor is installed,

such as a towing 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 acci-

dent 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

●

When your vehicle is towing a

trailer or during emergency tow-

ing

The Parking Support Brake can
be enabled/disabled on the
multi-information display. All of
the Parking Support Brake func-

If the engine output restriction con-
trol or brake control operates, a
buzzer will sound and a message
will be displayed on the audio sys-
tem screen and multi-information
display, to alert the driver.
Depending on the situation, engine
output restriction control will oper-
ate to either limit acceleration or
restrict output as much as possible.

If the Parking Support Brake

has operated

If the vehicle is stopped due to oper-

ation of the Parking Support Brake,

the Parking Support Brake will be

disabled and the PKSB OFF indica-

tor will illuminate. If the Parking Sup-

port Brake operates unnecessarily,

brake control can be canceled by

depressing the brake pedal or wait-

ing for approximately 2 seconds for

it to automatically be canceled.

Then, the vehicle can be operated

by depressing the accelerator pedal.

Re-enabling the Parking Sup-

port Brake

To re-enable the Parking Support

Brake when it has been disabled

due to system operation perform

any of the following operations.
At this time, the PKSB OFF indicator

will turn off. (

A sensor may be covered with ice,

snow, dirt, etc. Remove the ice,

snow, dirt, etc., from the sensor to

return the system to normal.

If this message is shown even

after removing dirt from the sen-

sor, or shown when the sensor

was not dirty to begin with, have

the vehicle inspected by your Toy-

ota dealer.

●

A sensor may be frozen. Once the

ice melts, the system will return to

normal.

●

Water may be continuously flow-

ing over the sensor surface, such

as in a heavy rain. When the sys-

tem determines that it is normal,

the system will return to normal.

■

If a battery terminal has been

disconnected and reconnected

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.

Detection range of the Parking

Support Brake function (static

Multi-terrain Select

(AWD models)

Multi-terrain Select is a sys-
tem that improves drivabil-
ity in off-road situations.

When driving over muddy,
sandy or rough road sur-
faces, the system selects a
suitable driving mode to
switch AWD, brake and
drive force control to per-
form control suitable for the
road condition.

WARNING

■

Before using Multi-terrain

Select

Make sure to observe the follow-

ing precautions. Failure to

observe these precautions may

result in an unexpected accident.

●

Check that the Mud & Sand and

Rock & Dirt indicators are illumi-

nated before driving. Multi-ter-

rain Select will not operate

when the indicators are off.

●

Do not rely solely upon the

Multi-terrain Select. This func-

tion is not intended to expand

the limits of the vehicle. If the

system is continuously used for

a long period of time, the load

on related parts increases and

the system may be unable to

operate normally, which may

lead to an accident. Thoroughly

check the road conditions and

driving route before driving, and

drive with caution.

Multi-terrain Select

●

Multi-terrain Select is intended for

use when driving on rough roads.

Drive in normal mode during nor-

●

The Mud & Sand and Rock & Dirt

modes control the vehicle so that

it can maximize the drive force

and improve drivability on rough

roads. As a result, fuel efficiency

may diminish when compared to

driving in normal mode.

is approximately 25 mph (40

km/h) or more

●

At this time, the buzzer sounds

intermittently and “Traction Con-

trol Turned OFF” is displayed on

the multi-information display.
