i-ACTIVSENSE

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 Smart City Brake Support [Reverse] (SCBS R) may or may not operate.

The Smart City Brake Support [Reverse] (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 Smart City Brake Support [Reverse] (SCBS R) is not turned off.

• The DSC is not malfunctioning.

The Smart City Brake Support [Reverse] (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 Smart City Brake Support [Reverse] (SCBS R) may not operate.

• The height of the obstruction is low such as low walls or trucks with low loading platforms.

• The height of the obstruction is high such as trucks with high loading platforms.

• The obstruction is small.

• The obstruction is thin such as a signpost.

• The obstruction is positioned away from the centre of the vehicle.

• The surface of the obstruction is not pointed vertically relative to the vehicle.

• The obstruction is soft such as a hanging curtain or snow stuck to a vehicle.

• The obstruction is shaped irregularly.

• The obstruction is extremely close.

In the following cases, the ultrasonic sensors (rear) cannot detect obstructions correctly and the Smart City Brake Support [Reverse] (SCBS R) may not operate.

• Something is stuck on the bumper near an ultrasonic sensor (rear).

• The steering wheel is turned sharply, or the brake or accelerator pedal is operated.

• There is another obstruction near one obstruction.

• During inclement weather such as rain, fog and snow.

• High or low humidity.

• High or low temperatures

• Strong winds.

• The path of travel is not flat.

• Heavy luggage is loaded in the luggage compartment or on the rear seat.

• Objects such as a wireless aerial, fog light, or illuminated number plate is installed near an ultrasonic sensor (rear).

• The orientation of an ultrasonic sensor (rear) has deviated for reasons such as a collision.

• The vehicle is affected by other sound waves such as the horn, engine noise, ultrasonic sensor of another vehicle.

In the following cases, an ultrasonic sensor (rear) may detect something as a target obstruction which could cause the Smart City Brake Support [Reverse] (SCBS R) system to operate.

• Driving on a steep slope.

• Wheel blocks.

• Hanging curtains, gate poles such as at toll gates and railroad crossing.

• When travelling near objects such as foliage, barriers, vehicles, walls, and fences along a road.

• When driving off-road in areas where there is grass and forage.

• When passing through low gates, narrow gates, car washing machines, and tunnels.

• A towing bar is installed or a trailer is connected.

(Manual transaxle)

If the vehicle is stopped by the SCBS operation and the clutch pedal is not depressed, the engine stops.

When the system operates, the user is notified by the multi-information display.

The Smart City Brake Support (SCBS) warning indication (amber) turns on when the system has a malfunction.
