Smart City Brake Support [Forward] (SCBS F)
The SCBS F system is designed to reduce damage in the event of a collision by operating the brake control (Smart City Brake Support (SCBS) brake) when the system's laser sensor detects a vehicle ahead and determines that a collision with a vehicle ahead is unavoidable. It may also be possible to avoid a collision if the relative speed between your vehicle and a vehicle ahead is less than about 20 km/h (12 mph).
In addition, when the driver depresses the brake pedal while the system is in the operation range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied firmly and quickly to assist. (Brake Assist (Smart City Brake Support (SCBS) brake assist))
Do not rely on the SCBS F as a substitute for safer driving:
The SCBS F system cannot compensate for unsafe and reckless driving, excessive speed, tailgating (following another vehicle too closely), and driving on slippery roads such as wet, snowy, and icy roads (reduced tyre friction and road contact because of water on the road surface). You can still have an accident.
Do not rely completely on the SCBS F system:
-
The SCBS F system is only designed to reduce damage in the event of a collision. Over reliance on the system leading to the accelerator pedal or brake pedal being mistakenly operated could result in an accident.
-
The SCBS F is a system which operates in response to a vehicle ahead. The system may not be able to detect or react to two-wheeled vehicles or pedestrians.
-
The laser sensor for the SCBS F system is installed near the rearview mirror. To assure the correct operation of the SCBS F, heed the following cautions.
-
Do not apply stickers to the surface of the windscreen near the laser sensor (including transparent stickers). Otherwise, the laser sensor may not be able to detect vehicles ahead which could result in an accident.
-
Do not apply coating agent to the windscreen. Otherwise, the laser sensor may not be able to detect vehicles or obstructions in front which could result in an accident.
-
Do not disassemble the laser sensor.
-
If cracks or damage caused by flying gravel or debris is visible near the laser sensor, stop using the SCBS F system immediately and have your vehicle inspected by an expert repairer, we recommend an Authorised Mazda Repairer. If the vehicle continues to be driven with cracks or scratch marks left on the windscreen near the laser sensor, the system may operate unnecessarily and cause an unexpected accident.
Refer to Stopping The SCBS F System Operation (Search).
-
When replacing the windscreen wipers or windscreen, consult an expert repairer, we recommend an Authorised Mazda Repairer.
-
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly detect vehicles ahead. This will result in the SCBS F system not operating normally or mistakenly operating, which could cause a serious accident.
Turn off the SCBS F when the vehicle is running on a chassis roller or being towed:
Turn off the SCBS F system to prevent mistaken operation when the vehicle is running on a chassis roller or being towed.
Refer to the Stopping the SCBS F System Operation (Search) on how to turn off the Smart City Brake Support (SCBS) system.
-
When driving off-road in areas where there is grass or forage, it is recommended that the SCBS F system be turned off.
-
Always use tyres for all wheels that are of the specified size, and the same manufacturer, brand, and tread pattern. In addition, do not use tyres with significantly different wear patterns on the same vehicle as the SCBS F system may not operate normally.
-
The laser sensor includes a function for detecting a soiled windscreen and informing the driver, however, depending on the conditions, it may not detect plastic shopping bags, ice or snow on the windscreen. In such cases, the system cannot accurately determine a vehicle ahead and may not be able to operate normally. Always drive carefully and pay attention to the road ahead.
-
The SCBS F system will not operate if the driver is deliberately performing driving operations (accelerator pedal and steering wheel).
-
The SCBS F system will operate under the following conditions.
-
The engine is running.
-
The Smart City Brake Support (SCBS) warning light (amber) does not illuminate.
-
The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).
-
The SCBS F system is not turned off.
-
The DSC is not malfunctioning.
-
-
The SCBS F detects a vehicle ahead by emitting a near-infrared laser beam and receiving the beam reflected off the reflector of the vehicle ahead, and then using it for the measurement. Consequently, the SCBS F may not operate under the following conditions:
-
Reflection of the laser is poor due to the shape of the vehicle ahead.
-
The vehicle ahead is significantly dirty.
-
Under bad weather condition, such as rain, fog and snow.
-
The window washer is being used or the windscreen wipers are not used when it's raining.
-
The windscreen is dirty.
-
The steering wheel is turned completely left or right, or the vehicle is accelerated rapidly and comes close to the vehicle ahead.
-
Trucks with low loading platforms and vehicles with an extremely low or high profile.
-
Vehicles with certain shapes such as a vehicle carrier.
-
-
Under the following conditions, the SCBS F system may not operate normally.
-
Heavy luggage is loaded in the luggage compartment or on the rear seat.
-
If there is the possibility of partial contact with a vehicle ahead.
-
When driving on continuously curving roads, and entering and exiting exits.
-
Elongated luggage or cargo is loaded onto installed roof rails and covers the laser sensor.
-
Exhaust gas from the vehicle in front, sand, snow, and water vapour rising from manholes and grating, and water splashed into the air.
-
When towing a malfunctioning vehicle.
-
When driving with tyres having significantly different wear.
-
-
When the vehicle is driven in the following locations, the SCBS F may determine that there is a possibility of a collision and may operate.
-
Objects on the road at the entrance to a curve.
-
Vehicles passing in the opposite lane while making a curve.
-
Metal objects, bumps, or protruding objects on the road.
-
When passing through a toll gate equipped with a bar.
-
When passing under a vinyl curtain or flag.
-
Plastic objects such as pylons.
-
Two-wheeled vehicles, pedestrians, animals or standing trees.
-
-
When the vehicle is driven in the following locations with the inner/outer side of the near-infrared laser irradiation part (black printed area in the centre of the upper portion of the windscreen) fogged or covered in water droplets, the SCBS F may determine that there is a possibility of a collision and may operate.
-
The vehicle is driven into tunnels with low ceilings and on roads with structures above the road such as road signs.
-
The vehicle is driven close to structures on the road such as road signs and guardrails.
-
-
(Manual transaxle)
If the vehicle is stopped by the SCBS F operation and the clutch pedal is not depressed, the engine stops.
-
When the system operates, the user is notified by the flashing Smart City Brake Support (SCBS) indicator light (red) and the active driving display (Some Models).
-
The Smart City Brake Support (SCBS) warning light (amber) turns on when the system has a malfunction.
Refer to Warning Lights (Search).
