What is Front Cross Traffic Alert on the Sealion 7?

FCTA detects vehicles crossing ahead at junctions — warning you of traffic you may not see when pulling out. It uses the front radar and camera, so any front bumper repair that shifts these sensors affects FCTA accuracy alongside ICC and AEB. The Sealion 7 is the only BYD in the UK with this system.

Is the Sealion 7 calibrated the same way as other BYD models?

All UK BYD models share e-Platform 3.0, so the core calibration procedures are consistent. The Sealion 7 has additional systems (FCTA, Driver Fatigue Monitoring) that require verification during the process, but the sensor hardware and diagnostic protocols remain the same.

Can a garage that calibrates other BYD models also do the Sealion 7?

Yes — the e-Platform 3.0 architecture is shared across BYD's UK range, so calibration knowledge transfers directly. The Sealion 7 simply has more systems to verify. Our technicians calibrate the BYD Atto 3, Seal, and Dolphin using the same BYD-compatible equipment.

BYD Sealion 7 ADAS Calibration

The Sealion 7 carries the most comprehensive DiPilot specification of any BYD sold in the UK – including Front Cross Traffic Alert, a system that most competing mid-size SUVs do not offer. If your Sealion 7's Adaptive Cruise or Lane Keep Assist has flagged a fault after bodywork, every sensor in BYD's proprietary suite needs to be checked with specialist equipment.

ADAS Systems on Your BYD Sealion 7

The Sealion 7 (2025+ UK) is BYD's latest mid-size SUV on e-Platform 3.0, featuring the most extensive DiPilot package in the UK range:

Automatic Emergency Braking (AEB) – front radar and camera working together at speeds up to 100 km/h
Intelligent Cruise Control (ICC) – front millimetre-wave radar behind the bumper
Lane Keep Assist (LKA) and Lane Departure Warning (LDW) – windscreen camera behind the rearview mirror
Blind Spot Detection (BSD) – rear-quarter panel sensors
Rear Cross Traffic Alert (RCTA) and Rear Cross Traffic Brake (RCTB) – active intervention system that brakes during reversing
Front Cross Traffic Alert (FCTA) – detects crossing traffic at junctions, unique to the Sealion 7 in BYD's UK lineup
360° Surround View Camera – four exterior cameras
Traffic Sign Recognition (TSR) – forward camera reading speed signs
Driver Fatigue Monitoring – interior camera monitoring alertness

FCTA is a differentiator – it uses the front radar and camera to detect vehicles crossing ahead at T-junctions and intersections. This system requires precise sensor alignment to function correctly.

Common Calibration Triggers for the BYD Sealion 7

Front bumper repair affecting multiple systems: A single front-end impact on the Sealion 7 can affect ICC, AEB, and FCTA simultaneously because all three rely on the front radar. Radar calibration after bumper work restores all three systems in one appointment.

Windscreen replacement: The forward camera controls LKA, LDW, TSR, and contributes to AEB. A windscreen swap requires camera recalibration – our £199 service includes verification of all camera-dependent systems.

Rear bumper work with active RCTB: The Sealion 7's Rear Cross Traffic Brake physically applies the brakes when it detects a vehicle approaching from the side during reversing. Rear bumper repairs that displace the rear radar sensors can cause RCTB to malfunction. This is not just an inconvenience – it is a safety-critical issue requiring immediate recalibration.
