Lane Departure Warning (LDW) and Intelligent Lane Intervention Overview
The 2022 Nissan Altima prioritizes safety with the inclusion of Lane Departure Warning (LDW) and Intelligent Lane Intervention technologies. These features, part of the Nissan Safety Shield 360 suite, aim to enhance driver awareness and contribute to safer driving experiences.
Understanding LDW System Operation
The LDW system utilizes a windshield-mounted camera to monitor the vehicle’s position in relation to lane markers. When the vehicle exceeds approximately 37 mph (60 km/h) and starts drifting without the turn signal engaged, LDW activates an audible and visual warning. The steering wheel vibration, accompanied by the blinking LDW indicator, alerts the driver, prompting corrective action.
User Guide: Enabling/Disabling LDW System
For vehicles with a 7-inch display, users can manage LDW settings by accessing “Driver Assistance” through the vehicle information display. Meanwhile, those with a 5-inch display can navigate to “Driving Aids” and then “Lane” to control LDW activation.
LDW System Limitations and Conditions
The LDW system has specific limitations that users must be aware of to ensure its effective operation. These include a minimum operating speed of 37 mph (60 km/h) and the requirement for clear lane markings. Additionally, adverse weather conditions, slippery roads, and certain road configurations can impact the system’s functionality.
Temporary Unavailability and System Malfunction
In cases of high cabin temperature, the LDW system may be temporarily unavailable, displaying a corresponding message. If the system malfunctions, automatic deactivation occurs, and users are advised to address the issue promptly by restarting the engine. Continued malfunctions necessitate a visit to a Nissan dealer for inspection and service.
BSW/LDW Automatic Deactivation: Maintenance and Troubleshooting
The Blind Spot Warning (BSW) and LDW systems can deactivate automatically when the camera accumulates dirt, rain, or snow, impeding proper detection. The BSW and LDW lights will blink, accompanied by a message indicating the need for camera cleaning.
Proper maintenance of the LDW system involves keeping the windshield clean and avoiding obstructions near the camera unit. Users are cautioned against damaging the camera unit or interfering with its components. Regular inspection and adherence to maintenance guidelines contribute to sustained system functionality.
Troubleshooting BSW/LDW Systems
In the event of system malfunctions, users should safely stop the vehicle, turn off and restart the engine. If the issue persists, seeking professional assistance from a Nissan dealer is recommended to address and rectify the problem.
