BYD Seagull Long-Term Storage: Breathable Cover, Dry Cabin

BYD Seagull long-term storage: breathable covers, a dry cabin, the right place

Scope: BYD China-mainland 2026 Seagull, based on official website owner's manual file 260317; actual equipment and later software differences need confirming from the vehicle's official information. This article covers only coverings, drying and choice of location for long-term storage; it does not apply to other markets, model years or models, and is not a complete checklist for storing the car, maintaining power supply or bringing it back into use.

Before covering, check where the car is parked

When preparing to leave the car unused for a long time, deal with the parking place and the bodywork first, then think about which cover to buy. This version of the manual treats more than one month as long-term parking that needs preparation, and recommends keeping the car indoors where possible; the paint care section also recommends a garage or a well-ventilated place for long-term parking. Owners can record the expected parking period, whether the place is ventilated and whether a cover is used, to explain the actual conditions to the workshop. This is an editorial suggestion for communication, not an environmental test standard from the manufacturer. Indoor parking also can't be taken to mean the car needs no further care; this article only explains the requirements relating to covers and drying, and full storage should be checked against the relevant manual and service advice. ^[1]

Choose material for breathability, not waterproof claims

The manual recommends breathable covers made of porous materials such as cotton, and explains that non-porous materials such as plastic sheeting can trap moisture and damage the paint. When buying, the questions worth asking are whether the cover breathes and how its instructions describe long-term covering conditions, not treating thicker or more tightly sealed as better for storage. The basis here is the manual's distinction between porous and non-porous covers; it can't be extended to say every plastic material is unsuitable, nor is the word "waterproof" proof of breathability. The page gives no breathability figures, brands or specifications for car covers, so this article lists no general compatible models and invents no material grade guaranteed not to trap moisture. ^[1]

A dry body and a dry cabin are joint conditions

The same storage section requires the exterior to be washed and dried, and the interior to be cleaned, with carpets and floor mats completely dry. So preparation should include checking both outside and inside, without treating putting the cover on as the signal that storage preparation is finished. Owners can record cleaning dates and any damp spots; if dampness, odours or signs of water ingress keep recurring, have professionals find the cause before deciding on storage, which is editorial service advice, not a diagnostic conclusion from the manual. This article sets no drying time in hours and gives no steps for releasing the parking brake, disconnecting power or maintaining charge; these affect the whole car and should follow the vehicle's official information and professional guidance. ^[1]
