Toyota parking assist-sensor

The Toyota parking assist-sensor is a

warning system to aid parking the vehicle

at low speed (e.g. into a garage). It uses

an ultrasonic sensor, which checks the ap-

proximate distance to an obstacle. It will

inform you of the approximate distance to

an obstacle by displaying information on

the multi-information display and with

beeping sounds.

1. Front corner sensors

A front corner sensor is installed on each

corner of the front bumper, they inspect ob-

stacles and will sound a warning depending

on the distance to the obstacle. See “Front

corner sensors” on page 169 in this Section.

INDICATORS

2. Rear corner sensors

When an obstacle is detected, the indica-

tor bars will come on or flash, accompa-

nied by beeping. How many bars are lit or

flashing depends on the distance to the

obstacle.

A rear corner sensor is installed on each

corner of the rear bumper, they inspect ob-

stacles and will sound a warning depending

on the distance to the obstacle. See “Rear

corner sensors” on page 170 in this Section.

1. Detection by front corner sensors

2. Detection by rear corner sensors

3. Detection by back sensors

3. Back sensors (vehicles without rear

monitor system)

Two back sensors are installed near the

centre of the rear bumper, they inspect ob-

stacles and will sound a warning depending

on the distance to the obstacle. See “Back

sensors” on page 170 in this Section.

The approximate distance to the obstacle is

shown with up to 4 bars on the rear of the

vehicle and up to 3 bars on the front corners

and the rear corners of the vehicle.

When the obstacle is not detected any longer,

beeping will stop and the multi-information

display will return to the previous display.

PARKING ASSIST-SENSOR SWITCH

To use the parking assist-sensor, press

the parking assist-sensor switch with the

ignition switch set to ON. Pressing the

switch again will turn the parking assist-

sensor off.

When you turn the parking assist-sensor on,

the indicator light on the switch comes on and

a beep sounds for one second, indicating that

the parking assist-sensor is turned on.

If an error is detected in the Toyota parking

assist-sensor while self-checking, beeps

sound and a warning appears in the multi-in-

formation display. For details, see “Toyota

parking assist-sensor failure warning” on

page 173 in this Section.

The front corner sensors only operate

when the vehicle speed is less than about

10 km/h. It checks the approximate dis-

tance to obstacles at an angle to the front

of the vehicle, and sounds a warning de-

pending on the distance. This sensor does

not operate if the transmission is in “P”

position.

CAUTION

To avoid an accident or injury, make

sure you consider the following in-

formation when using the parking as-

sist-sensor:

The indicator bars come on depending on the

distance to the obstacle and flash when the

distance between the vehicle and the ob-

stacle is less than about 25 cm (0.8 ft.).

D Always drive slowly using the brakes

while visually confirming that you

have a safe distance around your ve-

hicle.

1. Approximately 37.5 cm (1.1 ft.) to 50 cm

(1.5 ft.) from the obstacle

D Always visually confirm safety which

is outside the sensor detection range

because the sensor detection range is

limited around the bumper. For the

sensor detection range, see “Detec-

tion range of sensors” on page 172 in

this Section.

2. Approximately 25 cm (0.8 ft.) to 37.5 cm

(1.1 ft.) from the obstacle

3. Within 25 cm (0.8 ft.) of the obstacle

Beeps: As the distance to the obstacle gets

closer, the interval of the intermittent sound

gets shorter, and then finally changes to a

continuous sound when the distance between

the vehicle and the obstacle is less than

about 25 cm (0.8 ft.).

D Drive slowly and monitor the parking

assist-sensor because it might take

time for the sensors to detect ob-

stacles.

CAUTION

D Indicators and beeps may not warn

you properly and the detection range

may be shortened depending on the

shape of the obstacle.

When you move your vehicle, be sure to

visually confirm the area around your

vehicle and drive slowly, or an accident

or injury may result.

D It might be difficult to hear beeps due

to the volume of audio or air flow

noise of the air conditioning.

OTHER EQUIPMENT

—Numerous obstacles are

detected on the front and rear

of the vehicle simultaneously

If the possibility of collision with the ob-

stacle is high as shown, the parking as-

sist-sensor warns the driver by continu-

ous beeping (repeating

7

intermittent

beeps and one longer beep as one cycle).

3. Both obstacles detected on the front

and rear of the vehicle are in areas

where continuous beeping should

sound:

If the possibility of collision with the ob-

stacles is very high as shown, the parking

assist-sensor warns the driver by continu-

ous beeping (repeating 3 quick beeps and

one longer beep as one cycle).

CAUTION

D To avoid an accident or injury, always

drive slowly using the brakes while vi-

sually confirming that you have a safe

area around your vehicle.

D It might be difficult to hear the beeps

due to the volume of audio or air flow

noise of the air conditioning.

When obstacles are detected on the front

and rear of the vehicle at the same time;

the multi-information display illuminates

their relevant indicator bars. And sounds

a beep as follows:

1. Obstacles detected on the front and

rear of the vehicle are not in areas

where continuous beeping should

sound:

The warning for the obstacle closer to the

vehicle will be issued. The above illustra-

tion indicates the obstacle detected by the

back sensors is closer to the vehicle. So,

the warning for the obstacle detected by

the back sensors will be given.

CAUTION

The Toyota parking assist-sensor may not

work properly in the following cases:

D When the bumper is damaged.

D When the part near the sensors is sub-

jected to a strong impact.

D When an accessory is installed within

the sensor detection range.

D When snow or mud gets on the sen-

sors. (If removed, the parking assist-

sensor will work properly.)

D When water is splashed from a high

pressure car wash or steam on the

sensors.

D When a sensor is covered with your

hand.

D When the vehicle is tilted.

D In extreme hot or cold weather

(In extreme cold weather, the error

display appears and the parking as-

sist-sensor becomes inoperative.)

D When driving on bumpy roads,

slopes, gravelled roads or grass.

D Devices issuing ultrasonic waves are

operated around your vehicle, such as

a horn from another vehicle, motor-

cycle engine, air braking sound from

heavy-duty vehicles.

The sensor detection range is limited

around the bumper. Be sure to confirm a

safe distance around your vehicle and

drive slowly.

D When another vehicle equipped with

ultrasonic sensors gets close to your

vehicle.

A (front and rear corner sensors): About 50

cm (1.5 ft.)

B (back sensors): About 150 cm (4.5 ft.)

∗

D When heavy rain or water is splashed

over the vehicle. (Drive carefully as

the braking distance may be affected.)

: The maximum detection distance of the

sensor varies depending on the size of the

obstacle. The sensor can detect a large ob-

stacle, such as a wall, up to 150 cm (4.5 ft.)

away. However, the detection distance of a

thin obstacle, such as a pole, is only 100 cm

(3.0 ft.).

D When a radio antenna or fender pole

is mounted on your vehicle.

D If a towing eyelet is installed on your

vehicle.

If foreign matter gets on the sensors and

the parking assist-sensor cannot detect

the object properly, the above message

appears. At this time, the vehicle symbol

and the indicator bars corresponding to

the faulty sensors flash for about 7 sec-

onds and 2 beeps sound 5 times.

After about 7 seconds, the sensor indica-

tor bars will cease flashing, however will

stay lit until the affected sensor is

cleaned. Furthermore, the vehicle symbol

will continue to flash until the affected

sensor is cleaned.
