2026 BYD Sealion 6 Overview

Owner's Manual

An owner’s manual is the primary guide to operating, maintaining and caring for the Sealion 6. It explains instrument clusters, driver-assistance behaviors, scheduled service intervals, recommended maintenance practices and safety warnings. Use it to learn charging procedures, tire pressure specifications, fuse locations and basic troubleshooting steps. The manual also outlines warranty terms, emergency procedures and tips to preserve battery longevity, helping owners maximize safety, reliability and resale value.

Introduction

The 2026 BYD Sealion 6 blends aerodynamic styling with electric efficiency and a spacious, tech-forward cabin. Designed as a refined mid-size fastback, it emphasizes low drag, crisp handling and everyday comfort. Interior materials range from durable textiles to premium leather in upper trims, while an open, driver-centric layout places screens and controls within easy reach. The Sealion 6 represents BYD’s commitment to sustainable mobility, combining practical range and modern safety.

Powertrains

Powertrain options include an efficient single-motor rear-wheel-drive setup and an available dual-motor all-wheel-drive arrangement for enhanced traction and acceleration. Battery chemistry leverages BYD’s Blade cell architecture for improved energy density and thermal stability. Owners can expect strong regenerative braking, configurable drive modes and rapid DC fast-charging support that minimizes downtime. Power delivery is tuned for smooth urban driving and confident highway passing, with software-managed efficiency enhancements.

Trims

Trim levels are designed to suit different priorities, starting with a well-equipped Standard model that includes safety systems, climate control and a generous infotainment display. Mid-level Plus and Premium trims add upgraded upholstery, larger wheels, an enhanced audio system and advanced driver aids. A Performance trim focuses on sportier suspension tuning, sharper throttle response and unique styling cues, while a Touring option emphasizes comfort, cargo flexibility and travel-oriented convenience.

Features

Technology highlights include an intuitive central touchscreen, customizable digital instrument cluster and seamless smartphone integration. Advanced driver-assistance features such as adaptive cruise control, lane-centering, automatic emergency braking and blind-spot monitoring are standard or available depending on trim. Comfort features span heated and ventilated seats, panoramic glass roof, multi-zone climate, ambient lighting and wireless charging. Over-the-air updates keep software current, while modular storage and thoughtful ergonomics make daily life easier for drivers.

User manual download

The BYD Sealion 6 owner manual for the 2026 model year is to be found in PDF downloadable format on this page. The owner manual for the model year 2026 is free and in English, but the repair manuals are usually not easy to get and may cost more.
