DESCRIPTION

• The sonar sensor installed to the front bumper and the rear bumper detects obstacles around the bumper.
• The sonar control unit changes the buzzer cycle and the warning of the sonar indicator (combination meter

and NAVI control unit display), according to a distance from an obstacle detected by the sonar sensor.

• The sonar control unit controls the buzzer cycle according to a buzzer drive signal.

• The sonar control unit controls the sonar indicator according to a sonar indicator display signal transmitted to

the combination meter and the around view monitor control unit via CAN communication. 

• The sonar system is used in Park assist. Refer to 

DAS-287, "System Description"

.

SONAR SYSTEM ACTIVATION CONDITION

The sonar system warns the driver of the presence or absence of obstacles by buzzer and the sonar indicator
when the following conditions are satisfied while the ignition switch is turned ON.

×

: Activation

NOTE:
• When a sonar system OFF switch is turned OFF, obstacle detection function stops. 
• When an obstacle is detected by the sensor, Buzzer sounds.
• The sonar control unit activates the warning buzzer for approximately 0.5 seconds after detecting the

reverse signal.

• The following items can be set for the sonar system on the settings screen of the combination meter.
- Only ON/OFF/Fr of sonar sensor
- Detection range of sonar sensor
- Buzzer volume

OBSTACLE DETECTION DISTANCE

• The sonar control unit changes a buzzer cycle and a sonar indicator indication according to a distance from

an obstacle.

Obstacle detection range image

• Detection distance of an obstacle changes, as shown in the table below, when the detection sensitivity is

changed on the settings screen of the information display of the combination meter. Refer to 

MWI-71,

Detection distance

Sonar Indicator

• Sonar indicator is displayed on the information display in combina-

tion meter.

• The sonar control unit displays a warning on sonar indicator in 3 stages (green, yellow, and red), according

to a distance from an obstacle. 
NOTE:
• A distance from an obstacle is also displayed on the information display of the combination meter.
• Sonar indicator is displayed also on Bird-Eye view and Front-

side view screen of around view monitor.

• Warning displayed on the sonar indicator and a distance change according to a distance between an obsta-

cle and sensor as shown in the following table.

Detection distance (default value)

Warning Buzzer

• The warning buzzer output frequency changes levels according to the detection distance.
• As the vehicle approaches an obstacle, the buzzer-sounding cycle becomes shorter.
• The nearest sensor from the detected obstacle applies the buzzer output frequency if plural sensors detect

any obstacle simultaneously.

NOTE:
Buzzer stops when the vehicle moves away from an obstacle and the warning level decreases.

Trailer Hitch Mode

The trailer hitch mode allows the setting that the sonar sensor does not accidentally detect the trailer hitch as
an obstacle when connecting a trailer hitch.

SETTINGS

• Use “Work Support” of CONSULT and enter the distance to trailer hitch. Refer to 

SN-131, "CONSULT Func-

tion"

.

• Connect trailer hitch to the vehicle and drive approximately 10 seconds or more at 5 km/h (3.1 MPH).

How To Cancel The Setting

• Disconnect trailer hitch from the vehicle. Turn the ignition switch ON and maintain this state for 10 seconds

or more.
