The rubber strip on the car door frame is called the door sealing strip. It is a product that seals the car door, making it harder to open, and serves functions such as shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. Extended information: Functions: Mainly applied to door panels, door frames, side windows, front and rear windshields, engine hoods, and trunk lids, serving purposes in waterproofing, dust prevention, sound insulation, temperature insulation, shock absorption, and decoration. Composition: The door sealing system mainly targets two areas. One is the sealing of the door opening area, which relies primarily on an inner door sealing strip installed around the flanged edge of the side door opening or an outer door sealing strip installed around the door to seal the entire door opening. Some car models have both sealing strips, while others only have one. Different car models choose the sealing strategy based on performance requirements or cost objectives.

What does lifetime engine warranty mean?

Lifetime engine warranty means that when the vehicle's engine has quality issues within the manufacturer's specified warranty period, it can be repaired or replaced free of charge. Below is relevant information about the warranty: 1. Lifetime warranties generally come with many restrictions, such as the vehicle owner must be the first owner, maintenance must always be done at a 4S shop, only major components are covered (wear-and-tear parts are not), and the lifetime warranty becomes void after replacing major components. 2. Lifetime warranty is not the same as free repairs; it is the manufacturer's quality assurance commitment, not a guarantee that all repairs will be free. 3. Maintenance costs arising from normal wear and tear during vehicle use, not caused by product defects, are not covered under the warranty. 4. These items include but are not limited to: oil changes, oil filter replacement, fuel filter replacement, transmission fluid replacement, air filter replacement, cabin air filter replacement, fluid top-ups, tire rotation, paint polishing, engine carbon cleaning, engine tuning, engine belt replacement, etc. 5. The warranty covers non-human-caused part failures that can be claimed for replacement, excluding wear-and-tear parts and routine maintenance. In summary, a lifetime warranty does not mean free maintenance or repairs, and certain conditions must be met to enjoy the lifetime warranty.

Do Exempted Vehicles Still Require Annual Inspection?

Cars that have received an exemption mark are not exempt from annual inspections; they still need to undergo an inspection every two years, but the vehicle does not need to go to a testing station for the inspection. Vehicle annual inspection refers to a mandatory test for every vehicle that has obtained an official license plate and registration certificate, equivalent to an annual physical examination for the vehicle according to the 'Safety Technical Conditions for Motor Vehicle Operation'. The consequences of an expired vehicle inspection are as follows: 1. Vehicles that fail to undergo the annual inspection on time are not allowed on the road; 2. Vehicles driven on the road without timely annual inspection will be penalized with 3 points and a fine; 3. In the event of a traffic accident involving a vehicle that has not undergone the annual inspection, the party involved will bear full or primary responsibility, and the insurance company will not compensate; 4. Driving on the road without timely annual inspection is considered illegal driving and may result in the vehicle being impounded; 5. According to the 'Compulsory Scrapping Standards for Motor Vehicles', vehicles that fail to obtain an inspection qualification mark for three consecutive inspection periods after the expiration of the inspection validity period will be forcibly scrapped.

How to Turn On and Off Cruise Control?

Cruise control can be turned on and off as follows: 1. Activate Cruise Control: Briefly press the cruise control button, and the corresponding indicator light on the instrument cluster will illuminate white. Increase the vehicle speed to the desired cruising speed (above 40 km/h), then briefly press the set/decelerate button. The corresponding white indicator light on the instrument cluster will turn green. Once the vehicle enters cruise control mode, release the accelerator pedal. 2. Deactivate Cruise Control: Press the brake pedal, shift the gear lever to N (neutral), briefly press the cruise control button (this will exit cruise control and clear the set cruising speed), operate the Electronic Parking Brake (EPB) button, or if the ESP system is activated. 3. Resume Cruise Control: When the vehicle speed is above 40 km/h, briefly press the resume/accelerate button. The cruise control indicator light on the instrument cluster will change from white to green, and the vehicle will resume the previously set cruising speed. 4. Increase Cruising Speed: Briefly press the resume/accelerate button to increase the speed by 1.6 km/h per press.

What are the symptoms of a faulty urea nozzle?

The malfunctioning of the fuel injector nozzle leads to ineffective operation, resulting in severe carbon buildup inside the engine cylinders, accelerated wear of the cylinder liners and piston rings, unstable idle speed, increased fuel consumption, lack of power during acceleration, difficulty starting, and excessive vehicle emissions. In severe cases, it can even damage the engine. The specific causes leading to intermittent cylinder misfires are as follows: 1. Ignition System: Aging of the ignition coil and spark plugs causes the cylinder's ignition system to fail. Problems with the ignition coil most commonly result in reduced power, and in severe cases, can cause the engine to stall suddenly. 2. Cylinder Wire Wear: To check if the cylinder wires are functioning properly, simply remove the cylinder wire without needing a screwdriver, insert a spark plug, start the engine, and compare each cylinder to identify issues. 3. Fuel Injection System: Clogged injector nozzles or fuel lines prevent sufficient fuel from being supplied to the cylinder for combustion, naturally causing the cylinder to malfunction. 4. Excessive Spark Plug Carbon Buildup: Long-term poor combustion leads to carbon deposits accumulating at the spark plug ignition point. When these deposits are wetted by fuel, they create a parallel shunt resistance, resulting in spark plug leakage, weak sparks, or even complete spark plug failure.
