Mazda 3 Sedan 2023 Lane-keep Assist User Manual

Introduction

The pinnacle of grace, style, and cutting-edge technology is the Mazda 3 Sedan 2023. Its Lane-keep Assist system is one of several outstanding features that make this vehicle stand out. Lane-keep Assist is a ground-breaking function that aids in maintaining vehicle position inside the assigned lane. It is intended to improve safety and provide drivers peace of mind. Advanced sensors and clever algorithms are used by lane-keep Assist to keep track of the vehicle’s location on the road. The system actively maintains the Mazda 3 Sedan in the centre of the lane by examining the markings on the road surface. Lane-keep Assist gently steps in to offer corrective steering inputs if the car starts to inadvertently veer off its lane.

This cutting-edge technology works in tandem with the driver, providing an extra layer of protection to avert potential collisions brought on by brief lapses in concentration or driving weariness. Without impairing the driver’s control or input, lane-keep Assist offers a slight steering correction to help keep the car on course. The Lane-keep Assist system from Mazda is also made to adjust to different driving situations. It can operate safely at motorway speeds as well as slower rates on city streets. To precisely define the lane borders, the system recognizes the distinctive road markings, including solid and dashed lines. Because of its capacity to recognise and comprehend the road markings using specialised cameras and sensors, it can even function in low-light situations.

Lane-keep Assist

Lane-keep Assist System (LAS)
The LAS provides steering assistance to help the driver stay within the vehicle lane if the vehicle might be deviating. The forward sensing camera (FSC) detects the white lines (yellow lines) of the vehicle lane in which the vehicle is traveling and if the system determines that the vehicle may deviate from its lane, it operates the electric power steering to assist the driver’s steering operation. The system also alerts the driver by displaying an alert on the multi-information display. Use the system when you drive the vehicle on roads with white (yellow) lines such as expressways and highways.

WARNING

Do not rely completely on the LAS:

• The LAS is not an automated driving system. In addition, the system is not designed to compensate for a driver’s lack of caution, and over-reliance on the system could lead to an accident.
• The functions of the LAS have limitations. Always stay on course using the steering wheel and drive with care.
• Do not use the LAS under the following circumstances, otherwise it may result in an accident.
• The vehicle is driven on slippery roads such as icy or snow-covered roads, and unpaved roads.
• Tires of a different specified size are used, such as a temporary spare tire.
• Tires with insufficient tread are used.
• The tire pressures are not adjusted to the specified pressure.
• The vehicle is being used to tow a camper or boat trailer.
• Tire chains are used.
•  The vehicle is driven on roads with lane lines other than white (yellow) lines, such as an expressway.

CAUTION
Heed the following cautions so that the LAS can operate normally.

• Do not modify the vehicle’s suspensions.
• Always use tires of the specified type and size for the front and rear wheels. Consult an Authorized Mazda Dealer for tire replacement.
• NOTE
  The system may not operate normally under the following conditions.
• The white (yellow) lane lines are less visible because of dirt or paint flaking.
• White (yellow) lane lines are less visible because of bad weather (rain, fog, or snow).
• The vehicle is driven on a temporary lane or section with a closed lane resulting from construction where there might be multiple white
  (yellow) lane lines, or they are interrupted.
•  The camera picks up an obscure line, such as a temporary line being used for construction, or because of shade, unbelted snow, or grooves filled with water.
• The surrounding brightness suddenly changes such as when entering or exiting a tunnel.
• Back-light is reflected off the road surface.
• The road surface is wet and shiny after rain, or there are puddles on the road.
• The width of a lane is excessively narrow.
• The vehicle is driven on roads with tight curves.
• Heavy luggage is loaded in the trunk/luggage compartment or on the rear seat causing the vehicle to tilt.
• The vehicle is driven through a fork in the road or a junction.
• The shade of a guardrail parallel to a white (yellow) lane line is cast on the road.
• The illumination of the headlights is weakened because of dirt or the optical axis is deviated at night.
• The road is excessively uneven.
• The vehicle is shaken after hitting a road bump.
• A vehicle in front of your vehicle is running near a white (yellow) lane line making it less visible.
  The windshield is dirty or foggy.
• Strong light is directed from the front of the vehicle (such as sunlight, or headlights (high-beam) of on-coming vehicles).

System Operation
When the ignition is switched ON, the i-ACTIVSENSE status symbol (warning/risk avoidance support system) (white) turns on and the system goes on standby.

NOTE
If the i-ACTIVSENSE status symbol (warning/risk avoidance support system) (white) does not turn on, the system is canceled using the
i-ACTIVSENSE OFF switch or the personalization feature.

Operation conditions
When all of the following conditions are met, the i-ACTIVSENSE status symbol (warning/risk avoidance support system) on the multi-information display changes from white to green and the system becomes operational.

• The vehicle speed is about 64 km/h (40 mph) or faster.
• The system detects white (yellow) lane lines.

NOTE
When the system does not detect a white (yellow) lane line on one side only, the system does not operate on the side that is not being detected.

When temporarily canceling the system
The LAS goes on standby in the following cases: The LAS operation is automatically restored when the system’s operation conditions are met.

•  The system cannot detect white (yellow) lane lines.
• The vehicle speed is less than about 56 km/h (35 mph).
• The turn signal lever is operated.
• The accelerator pedal is depressed abruptly.
• The TCS/DSC is operating.
• The TCS/DSC is turned off.
• The steering wheel is operated.
• The brake pedal is operated.
  The function is temporarily stopped.

The LAS stops functioning in the following cases:

• The temperature in the forward sensing camera (FSC) is too high or too low.
• The windshield around the forward sensing camera (FSC) is foggy.
• The windshield around the forward sensing camera (FSC) is blocked by an obstruction, causing poor forward visibility.
• Strong light (such as sunlight, or headlights (high-beam) of on-coming vehicles) is directed at the forward sensing camera (FSC).

System malfunction
If there is a problem with the system, the i-ACTIVSENSE status symbol (warning/risk avoidance support system) (white) and the i-ACTIVSENSE warning indication/warning light on the multi-information display turns on and a message is indicated. Refer to i-ACTIVSENSE Status Symbol (Warning/Risk Avoidance Support System).

Steering Wheel Operation Assist
When the system determines that the vehicle might be deviating from its lane, the steering wheel operation assist operates. The system notifies the driver that it provided steering wheel operation assistance on the multi-information display and the active driving display. Multi-information display (Basic display)

Multi-information display (i-ACTIVSENSE display)

Active driving display

NOTE

• When the driver operates the steering wheel while the steering wheel operation assist is operating, the steering wheel operation assistance is canceled.
• System Canceling
  The LAS can be set to inoperable.
• (If only the LAS is turned off)
  Refer to the Settings section in the Mazda Connect Owner’s Manual.
  (If the LAS is turned off by operating the i-ACTIVSENSE OFF switch) Refer to i-ACTIVSENSE OFF Switch on page 4-100.
