The Mercedes-Benz E300L suddenly brakes on its own due to its collision prevention system. The collision prevention system is an automatic braking function designed to simplify operations by avoiding the use of hand brakes or electronic parking brakes. Taking the 2021 Mercedes-Benz E260L as an example, its body dimensions are: length 5078mm, width 1860mm, height 1484mm, with a wheelbase of 3079mm. The 2021 Mercedes-Benz E260L features a multi-link independent suspension at the front and rear, and is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 184PS, a maximum power of 135kW, and a maximum torque of 280Nm, paired with a 9-speed automatic transmission.

The issue of the Mercedes-Benz E300L suddenly braking on its own is quite common, and I have experienced a similar scenario once. The main reason lies in the false triggering of the vehicle's active safety system. This car is equipped with a pre-collision protection function that automatically brakes to prevent collisions when the radar or camera detects potential obstacles. Common causes include dirty sensors, such as mud or rainwater blocking the signal, leading the system to mistakenly judge a hazard ahead. Or, outdated software updates may cause bugs, making the system overly sensitive at low speeds. I once resolved the issue by cleaning the front sensors myself. It is recommended that owners regularly maintain these areas and check the settings menu to reduce sensitivity. If it occurs frequently, it is necessary to visit a 4S shop to read the fault codes and ensure the circuits and modules are functioning properly. Safe driving should always be prioritized, as unexpected braking increases the risk of rear-end collisions and should not be overlooked.

How often should the timing belt on the Octavia be replaced?

The timing belt on the Octavia generally needs to be replaced every 60,000 to 80,000 kilometers. If the mileage hasn't been reached, but the belt has been in use for more than 5 years, it should also be inspected. If the timing belt suddenly breaks while driving, it can cause engine damage and affect the operation of other systems, such as brakes, steering, and power generation. Below are some details about the timing belt: 1. The timing chain is an upgraded replacement for the timing belt. Under normal usage, it is maintenance-free for life and has the same lifespan as the engine, so it doesn't need replacement. 2. The main function of the engine timing belt is to drive the engine's valve train, ensuring that the intake and exhaust valves open and close at the appropriate times to allow the engine cylinders to properly intake and exhaust air.
