If the engine sometimes fails to start, you can go to a 4S shop to remove carbon deposits from the vehicle. Below is relevant information about car engine maintenance: Use qualified lubricating oil: For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the oil and filter: To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be moderate (generally up to the upper limit of the oil dipstick). Additionally, when the filter is clogged and oil cannot pass through the filter element, it may burst the filter element or open the safety valve, allowing oil to pass through the bypass valve and still carry contaminants back to the lubrication parts, accelerating engine wear and worsening internal pollution.

How to Turn on the Headlights of a Focus?

Methods to turn on the headlights of a Focus: 1. New Focus: Rotate the headlight switch left or right. 2. Classic Focus or older Focus models: Rotate the headlight switch. Information about headlight signals: 1. Overtaking or when the car in front doesn't move after the light turns green: Flash the headlights once or twice. At an intersection, when the light turns green, sometimes the car in front may not move, possibly due to a nervous beginner or the driver not noticing the light change. In such cases, the following car usually takes some action to give a hint. 2. Encountering strong lights when meeting another car at night: Flash the headlights twice. The most annoying thing when driving at night is encountering inconsiderate drivers who keep their high beams on. In such situations, flash your headlights twice from a distance to remind the other driver to switch lights. If there's no response, you can also briefly turn on your high beams and then quickly turn them off as a reminder. 3. Kindly reminding the other driver to check their car's condition: Flash the headlights three times and use the horn as an additional reminder. While driving, if you notice that the car in front has an unclosed door or significantly low tire pressure, you can flash your headlights three times continuously. Wait for the driver to notice, then flash three more times. If someone flashes their headlights at you three times, pay attention as it might be a friendly reminder that there's something wrong with your car.

Does an occasional sudden brake affect the car?

An occasional sudden brake does not harm the vehicle. Here is the relevant information: Brake assist system activation: When the brake is suddenly pressed, the ABS brake assist system and EPS electronic stability system will activate to maintain the normal operation of the vehicle. An occasional sudden brake, apart from causing relatively greater wear on the brake friction pads and tires, and consuming slightly more fuel when restarting, other damages are minimal and can be largely ignored. Notes: Especially for automatic transmission cars, releasing the accelerator before braking will not involve any damage to the transmission or engine. However, frequent sudden braking can cause significant damage to the vehicle, mainly manifested in tire wear, brake pad wear, impact deformation of the suspension system, and impact damage to the transmission system. Emergency use: Therefore, sudden braking should generally be avoided, but the car's structure is carefully designed and will not immediately break down due to sudden braking. So, in emergency situations, do not hesitate to use sudden braking.
