Is it necessary to go to a 4S shop for inspection before driving on the highway?

It is recommended to have your vehicle inspected at a 4S shop before driving on the highway, as long-distance high-speed driving is an extreme working condition for the vehicle. Many parts and systems may fail due to excessive load, damage, or aging, posing significant safety hazards. Additionally, 4S shops are equipped with professional instruments and experienced technicians who can promptly identify potential safety issues. Below are the relevant inspection details: 1. Tire inspection: 1. Visually check for signs of cracks, bulges, aging, or punctures. If unsure whether a damaged area is leaking, you can spray soapy water on the "wound" to observe. 2. Check tire pressure. Vehicles equipped with a tire pressure display system can directly read the pressure on the instrument display. For high-speed driving, the recommended tire pressure is between 2.2-2.5 bar. In summer, it can be slightly reduced by 0.1-0.2 bar to prevent tire blowouts. 3. Tires with tread depth less than 1.6mm should be replaced promptly. Most high-speed chain-reaction accidents are caused by insufficient vehicle traction on wet roads due to shallow tread depth, which also reduces friction. 2. Fluid inspection: 1. Engine oil check. Ensure there is sufficient engine oil, as high-speed engines require ample lubrication, and the oil also dissipates most of the heat. 2. Coolant check. Prolonged high-speed driving can cause the engine temperature to rise. Insufficient coolant may lead to engine overheating, resulting in smoke or even fire in the engine compartment. 3. Brake fluid check. Brake fluid must not deteriorate, as this can cause it to boil easily, leading to insufficient braking force.
