BYD DOLPHIN

This page is an independent, unofficial reference guide covering the DiPilot driver assistance and active safety systems fitted to the BYD DOLPHIN pure electric hatchback sold in Australia. It explains how the main systems function and what steps are appropriate when a system alert appears or performance seems degraded. Because ADAS calibration, sensor alignment and airbag-related work are safety-critical, all such tasks must be performed by an authorised BYD dealer or qualified technician — this guide does not provide step-by-step repair instructions for those procedures.

Trim names, specifications and feature details reflect a compiled dataset (October 2026). BYD Automotive Australia may update variants, equipment lists or software at any time, so every item described here must be confirmed with an authorised BYD dealer or at the official BYD Australia website.

DiPilot System Overview

BYD’s DiPilot is the suite of active driver assistance technologies integrated into the BYD DOLPHIN. Both the Essential and Premium variants are equipped with an extensive set of features including adaptive cruise control, automatic emergency braking, lane departure assist, lane keeping support, blind spot detection, rear cross traffic alert and brake, front cross traffic alert and brake, emergency lane keeping assist, lane change collision warning, predictive collision warning, rear collision warning, intelligent speed limit information and control, traffic sign recognition, indirect driver fatigue monitoring, child presence detection, and door open warning.

Because these systems rely on sensors and software working in precise coordination, any software behaviour change or physical damage that may affect calibration should be assessed by an authorised BYD dealer. The BYD DOLPHIN also supports over-the-air (OTA) software updates, which can refine DiPilot behaviour; refer to the official owner’s manual for guidance on managing OTA updates.

Automatic Emergency Braking and Collision Warning

The BYD DOLPHIN is fitted with automatic emergency braking (AEB), which is designed to detect a potential collision and apply braking if the driver does not respond in time. Complementing AEB are predictive collision warning, rear collision warning, and front and rear cross traffic alert and brake. The rear cross traffic alert system is particularly useful when reversing from a car park bay, as it detects vehicles approaching from either side and issues an alert; the system is listed in the official specifications as “rear cross traffic alert and brake” — for precise details of how braking activation operates, refer to the official owner’s manual or consult an authorised BYD dealer.

If an AEB-related warning appears on the instrument panel or the system appears to have activated unexpectedly, the first step is to check that all forward-facing sensors and the windscreen area ahead of any detection equipment are clean and unobstructed. Windscreen replacement or repair near any forward-facing detection component must be followed by ADAS recalibration; this work must be performed by an authorised BYD dealer or qualified technician, as autonomous emergency braking calibration is a safety-critical procedure. Confirm with BYD Automotive Australia or your local dealer whether a specific windscreen repair requires recalibration before driving the vehicle.

Lane Assistance Systems

The BYD DOLPHIN includes lane departure assist, lane keeping support, emergency lane keeping assist, and lane change collision warning. Lane departure assist alerts the driver when the vehicle drifts towards a lane marking without a turn signal, while lane keeping support applies a gentle steering input to guide the car back within the lane. Some drivers notice a brief sensation at the steering wheel when lane keeping support intervenes — this is the system operating as intended and is not a fault in itself.

If lane keep assist produces unexpected steering wheel feedback, persists when the driver is actively steering, or the system warning light remains illuminated after restarting the vehicle, the forward-facing detection equipment alignment should be checked. Misalignment after even a minor impact can affect system accuracy. Because this involves detection equipment and steering system interaction, any inspection or recalibration must be referred to an authorised BYD dealer. Also refer to the official owner’s manual for details on enabling, disabling or adjusting the sensitivity of individual lane assistance features — settings can vary depending on trim level and current software version.

Adaptive Cruise Control and Speed Assistance

Adaptive cruise control on the BYD DOLPHIN maintains a set following distance from the vehicle ahead by automatically adjusting speed. Working alongside this are intelligent speed limit information and control, and traffic sign recognition — the traffic sign recognition system reads road signs and can display the relevant speed limit on the instrument panel.

If the adaptive cruise control disengages unexpectedly or a system warning remains active after cleaning all exterior sensor surfaces, consult an authorised BYD dealer before relying on the feature. Speed limit control and traffic sign recognition accuracy can also be affected by worn, faded or non-standard road signage — the driver remains responsible for obeying posted speed limits at all times regardless of system state. Any persistent fault with adaptive cruise control is subject to manufacturer specifications and should be assessed by a qualified technician.

360-Degree View Monitor and Parking Sensors

The BYD DOLPHIN is equipped with a 360-degree view monitor, which is displayed on the 12.8-inch rotating touchscreen. Front parking sensors (two zones) and rear parking sensors (three zones) supplement the visual display with audible proximity alerts. Both the Essential and Premium variants include this equipment as confirmed in the official brochure; refer to the official owner’s manual for details on operating modes and display settings.

If the 360-degree view monitor shows distorted images, dead areas, or an incorrect composite view, check that all associated sensor and camera surfaces are clean and free from obstruction. A persistent image fault after cleaning — particularly after a body repair, tow-bar fitment or any panel work near a camera — may indicate that a component has been displaced or requires software recalibration. This type of recalibration is subject to manufacturer specifications and must be carried out by an authorised BYD dealer. Similarly, if parking sensors emit a constant tone or fail to respond, check for mud, ice or damage on the sensor faces before booking a service appointment.

Airbags and Passive Safety

The BYD DOLPHIN is equipped with front airbags, side airbags, side curtain airbags, and a driver far-side airbag. Front seat belts use dual-stage pretensioners. ISOFIX anchorage points are provided for compatible child restraints.

The airbag system, seat belt pretensioners and related restraint electronics are safety-critical components that must never be inspected, repaired or modified by anyone other than a qualified technician at an authorised BYD dealer. If the SRS (Supplemental Restraint System) warning light illuminates and does not clear after restarting the vehicle, the vehicle should be assessed without delay. Never attempt to open airbag modules, disconnect airbag wiring, or place objects between the seat and the door that might interfere with side airbag deployment. Child presence detection is also integrated into the passive safety suite; refer to the official owner’s manual for correct configuration of this feature.

ANCAP Safety Context

The official BYD Australia website for the BYD DOLPHIN displays the ANCAP safety logo, indicating the vehicle has been assessed by the Australasian New Car Assessment Program. To see the full star rating, test scores and detailed breakdown of the ANCAP assessment for the BYD DOLPHIN, visit www.ancap.com.au directly — the data available for this guide does not include a stated star rating, and BYD Automotive Australia should be contacted to confirm which test cycle and variant applies to Australian-delivered vehicles.

ANCAP assessments consider both crash protection (using physical test results) and safety assist (evaluating active systems such as AEB and lane keeping). The DiPilot suite on the BYD DOLPHIN contributes to the safety assist portion of any ANCAP evaluation. Confirm with BYD Automotive Australia whether any subsequent OTA software updates have affected the ANCAP-tested configuration.

Frequently Asked Questions

Does the BYD DOLPHIN’s AEB system need recalibration after a windscreen replacement?

Yes. Any work on or near the windscreen in the area where forward-facing detection equipment is mounted — including replacement or chip repair — can affect system aim. Autonomous emergency braking calibration after windscreen work must be performed by an authorised BYD dealer or qualified technician before the vehicle is returned to normal use.

Why does the lane keep assist produce a sensation at the steering wheel?

When lane keeping support detects the vehicle drifting across a lane marking without an indicated turn, it applies a brief steering input to guide the vehicle back within the lane. This feedback at the steering wheel is the system intervening as designed. If the sensation is unusually strong, occurs while the driver is actively steering, or is accompanied by a warning light, consult an authorised BYD dealer.

What does the rear cross traffic alert do when reversing the BYD DOLPHIN?

The rear cross traffic alert and brake system monitors for traffic approaching from the sides while the vehicle is reversing. If a vehicle is detected, the system issues an audible and visual alert. For full details of how the braking component of this system operates, refer to the official owner’s manual or consult an authorised BYD dealer.

How can a BYD DOLPHIN owner check the vehicle’s ANCAP safety rating?

The official source for ANCAP test results and star ratings is www.ancap.com.au. The BYD DOLPHIN’s result — including sub-scores for adult occupant protection, child occupant protection, vulnerable road user protection, and safety assist — is published there. The BYD Australia model page also displays the ANCAP logo; confirm details with BYD Automotive Australia.

What should be done if a DiPilot warning light does not clear after restarting the vehicle?

If any ADAS-related warning indicator remains illuminated after a vehicle restart and after checking that all sensors and detection surfaces are clean, the vehicle should be assessed by an authorised BYD dealer. Do not rely on the affected system until it has been checked, as its protective function may be reduced or inactive.

Can the 360-degree view monitor be recalibrated if it shows distorted images after a body repair?

If body work has been performed near any component contributing to the 360-degree view monitor, that component may have shifted from its calibrated position. Image distortion or misaligned display after a repair indicates the system should be recalibrated. This work is subject to manufacturer specifications and must be carried out by an authorised BYD dealer.
