Smart City Brake Support (SCBS)

Smart City Brake Support (SCBS)í

The Smart City Brake Support (SCBS) system is designed to reduce damage in the event of a collision by operating the brake control (SCBS brake) when the system's laser sensor detects a vehicle ahead and determines that a collision with the vehicle ahead is unavoidable. It may also be possible to avoid a collision if the relative speed between your vehicle and the vehicle ahead is less than about 15 km/h (9.3 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 (SCBS brake assist))

For vehicles with the type A instrument cluster, check the vehicle condition or have the vehicle inspected at an Authorized Mazda Dealer according to the indication.

WARNING

Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safe driving:

The Smart City Brake Support (SCBS) 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 tire friction and road contact because of water on the road surface). You can still have an accident.


Do not rely completely on the Smart City Brake Support (SCBS) system:

Ø The Smart City Brake Support (SCBS) 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.

Ø The Smart City Brake Support (SCBS) is a system which operates in response to a vehicle ahead. The system may not be able to detect or react to 2-wheeled vehicles or pedestrians.

Ø The laser sensor for the Smart City Brake Support (SCBS) system is installed near the rearview mirror. To assure the correct operation of the Smart City Brake Support (SCBS), heed the following

CAUTION

s.

Ø Do not apply stickers to the surface of the windshield near the laser sensor (including transparent stickers). Otherwise, the laser sensor may not be able to detect vehicles or obstructions ahead which could result in an accident.

Ø Do not disassemble the laser sensor.

Ø If cracks or damage caused by flying gravel or debris is visible near the laser sensor, stop using the Smart City Brake Support (SCBS) system immediately and have your vehicle inspected by an Authorized Mazda Dealer. If the vehicle continues to be driven with cracks or scratch marks left on the windshield near the laser sensor, the system may operate unnecessarily and cause an unexpected accident.

Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page 4-81.

Ø When replacing the windshield wipers or windshield, consult an Authorized Mazda Dealer.

Do not modify the suspension:

If the vehicle height or inclination is changed, the system will not be able to correctly detect vehicles or obstructions ahead. This will result in the Smart City Brake Support (SCBS) system not operating normally or mistakenly operating, which could cause a serious accident.

Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis roller or being towed:

Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation when the vehicle is running on a chassis roller or being towed. See the next page on how to turn off the Smart City Brake Support (SCBS).

Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page 4-81.

CAUTION

CAUTION

CAUTION

Ø When driving off-road in areas where there is grass or forage, it is recommended that the Smart City Brake Support (SCBS) system be turned off.

Ø Always use tires for all wheels that are of the specified size, and the same manufacture, brand, and tread pattern. In addition, do not use tires with significantly different wear patterns on the same vehicle. Do not use tires with significantly different wear patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not operate normally.

Ø The laser sensor includes a function for detecting a soiled windshield and informing the driver, however, depending on the conditions, it may not detect plastic shopping bags, ice or snow on the windshield. In such cases, the system cannot accurately determine a vehicle or obstruction ahead and may not be able to operate normally. Always drive carefully and pay attention to the road ahead.

NOTE

The Smart City Brake Support (SCBS) system will operate under the following conditions.

The engine is running.

The display in the instrument cluster does not indicate that the system requires inspection or it cannot be used.

The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).

The Smart City Brake Support (SCBS) system is not turned off.

The TCS operation is not turned off using the TCS OFF switch.

The DSC is not malfunctioning.

The driver is not deliberately performing driving operations (accelerator pedal, steering wheel, and braking operations).

The Smart City Brake Support (SCBS) 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 Smart City Brake Support (SCBS) 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 windshield wipers are not used when it's raining.

The windshield 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, vehicles traveling at extremely low speeds, and vehicles with a high profile.

Vehicles with certain shapes such as a vehicle carrier.


Under the following conditions, the Smart City Brake Support (SCBS) system may not operate normally.

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

When there is the possibility of partial contact with a vehicle or obstruction ahead.

When driving on continuously curving roads, entering and exiting curves, and unstable driving due to a vehicle accident or breakdown in a driving lane.

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 vapor rising from manholes and grating, and water splashed into the air.

When towing a malfunctioning vehicle.

In the following cases, the laser sensor may inadvertently determine that there is a vehicle ahead and the Smart City Brake Support (SCBS) system 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.

When passing under a vinyl curtain or flag.

Plastic objects such as pylons.

Two-wheeled vehicles, pedestrians, animals or standing trees.

If the vehicle is driven with some of the tires having significant wear, the system may not operate correctly. If the tires are returned to a normal state and the master WARNING light still illuminates, have your vehicle inspected by an Authorized Mazda Dealer.


Laser Sensor Handling

The Smart City Brake Support (SCBS) laser sensor is installed at the top of the windshield near the rearview mirror.

WARNING

As there is the possibility of eye damage occurring from the laser, always heed the following pre

CAUTION

s:

Ø Never remove the sensor.

Ø A removed sensor will not meet the conditions for a class 1M laser under the IEC 60825-1 specification and therefore eye safety cannot be assured.

Ø Do not peer into the sensor using optical instruments with a magnification function such as magnifying glasses, and microscopic and objective lenses within a distance of 100 mm (3.94 in) from the sensor.
