What does autodiff mean on a car?

Autodiff on a car refers to the auto differential lock. Below is an introduction about the dashboard: 1. Introduction: The dashboard is a rigid panel or structural component used to install instruments and related devices. It can be categorized into screen-type dashboards, frame-type dashboards, passage-type dashboards, and cabinet-type dashboards based on their design. The dashboard can come with external lighting and may also include a control console. It comes in various forms and sizes, allowing for the installation of different instruments as needed, or combining various dashboards into a single unit. 2. Types of indicator lights on the dashboard: door status indicator, parking indicator, various dashboard indicators, battery indicator, fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, turn signal indicators, high beam indicator, seat belt indicator, O/D gear indicator, recirculation indicator, width indicator, VSC indicator, TCS indicator, etc.
I have worked in the automotive industry for many years and often help friends with functional questions. The term 'autodiff' actually refers to the automatic differential lock function, primarily used in off-road vehicles with four-wheel drive systems. Simply put, when one of your vehicle's wheels gets stuck in mud and spins, the system automatically locks the differential, transferring power to the wheels with traction to help you get out easily. For example, if you're driving on a snowy mountain road and one front wheel spins in the air, autodiff will engage to lock the differential, allowing the other wheels to pull the vehicle forward. Compared to a manual differential lock, it doesn't require you to get out and operate it—it responds automatically, which is especially practical. However, it's rarely needed for everyday city driving, and keeping it engaged on paved roads for long periods can increase fuel consumption. I recommend familiarizing yourself with the function's switch location before off-roading, as this feature is particularly essential for desert and rainforest terrain.
