Do not apply a strong force to an ultrasonic sensor (rear):
When washing the vehicle, do not spray highly pressurised water against an ultrasonic sensor
(rear), or rub it strongly. In addition, do not hit the rear bumper forcefully when loading and
unloading cargo Otherwise, the sensors may not detect obstructions correctly which could
cause the SCBS R system to not operate normally, or it could operate unnecessarily.

¾
When driving off-road in areas where there is grass or foliage, it is recommended that the
SCBS R system be turned off.
¾
Always use tyres of the specified size and the same manufacturer, brand, and tread pattern
on all 4 wheels. In addition, do not use tyres with significantly different wear patterns on the
same vehicle. Otherwise, the SCBS R system may not operate normally.
¾
If ice or snow is stuck on the ultrasonic sensors (rear) they may not be able to detect
obstructions correctly depending on the conditions. In such cases, the system may not be
able to perform controls correctly. Always drive carefully and pay attention to the rear of
the vehicle.
NOTE
•
The vehicle posture changes depending on the accelerator pedal, brake pedal and
steering wheel operations, which could make it difficult for the system to recognise an
obstruction, or it could facilitate unnecessary detection. In such cases, the SCBS R may or
may not operate.
•
The SCBS R system will operate under the following conditions.
•
The engine is running.
•
The change lever (manual transaxle vehicle) or the selector lever (automatic transaxle
vehicle) is in the R (reverse) position.
•
“Reverse Smart City Brake Support Malfunction” is not displayed in the
multi-information display.
•
The vehicle speed is between about 2 to 8 km/h (2 to 4 mph).
•
The SCBS R is not turned off.
•
The DSC is not malfunctioning.
•
The SCBS R operates using ultrasonic sensors (rear) which detect obstructions at the rear
by emitting ultrasonic waves and then receiving the returning waves reflected off the
obstructions.
•
In the following cases, the ultrasonic sensors (rear) cannot detect obstructions and the
SCBS R may not operate.
•
The height of the obstruction is low such as low walls or trucks with low loading
platforms.
