Most methods involve dividing the car into three equal parts, aligning the outer one-third of the front hood with the right sideline while driving. From the driver's seat view, when the raised portion of the left wiper aligns with the right sideline on the ground, the car body is approximately 30cm away from the right edge. Through the right rearview mirror, observe the front door handle - when it appears tangent to the right sideline, the distance between the car body and the right road edge is roughly 30cm.

Where is the OBD port located on a BMW 5 Series?

The OBD port on a BMW 5 Series is located beneath a small cover panel near the area above the brake pedal. Detailed information about the OBD port is as follows: 1. OBD stands for On-Board Diagnostics, which translates to "vehicle diagnostic system" in Chinese. This system continuously monitors the engine's operating conditions and the working status of the exhaust after-treatment system, issuing immediate alerts when it detects any condition that might lead to excessive emissions. 2. As the communication interface for the vehicle monitoring system, the OBD port's primary function, besides reading fault codes for vehicle repairs, is to provide various operational data about the vehicle, including data not displayed on the vehicle's dashboard.

The Role of Vehicle Stability Control System

Vehicle stability control systems are divided into ABS (Anti-lock Braking System) and ASR (Anti-Slip Regulation) as automotive anti-skid devices. Their respective functions are: 1. During emergency braking, ABS prevents wheel lock-up; 2. When wheels slip, TCS (Traction Control System) controls engine output and wheel braking to prevent wheel spin. Below is an introduction to the stability control system: The Electronic Stability Program (ESP) intervenes when a vehicle is rapidly cornering, evading suddenly appearing cars or animals, or when understeer causes the vehicle to slide outward or oversteer makes it cross the centerline or even spin. It uses computer-controlled engine output and individual wheel braking to correct understeer or oversteer, thereby enhancing dynamic driving stability.
