    Hyundai Elantra (CN7) 2021-2025 Owner's Manual: System disabled


    When the rear bumper around the rear corner radar or sensor is covered with foreign material, such as snow or rain, or installing a trailer or carrier, it can reduce the detecting performance and temporarily limit or disable Blind-Spot Safety system. If this occurs, the ‘Blind-Spot Safety system(s) disabled. Radar blocked’ warning message will appear on the cluster. The system will o..

    Tachometer

    The tachometer indicates the approximate number of engine revolutions per minute (RPM).

    Use the tachometer to select the correct shift points and to prevent lugging and/ or over-revving the engine.

    NOTICE

    Do not operate the engine within the tachometer's RED ZONE. This may cause severe engine damage.
