Does the Vehicle Inspection Require Personal Attendance?

Vehicle inspection does not require personal attendance, as the annual vehicle inspection service can be handled by an agent. The process for insurance companies to handle the annual inspection on your behalf is as follows: 1. Prepare the vehicle license, driver's license, the previous year's vehicle inspection sticker, and a valid copy of the compulsory traffic insurance policy; 2. Make a phone appointment for the agency service. Once the appointment is confirmed, arrange the pickup time and location. At this point, the insurance company will remind the owner to prepare the required materials, as well as a valid onboard warning triangle and fire extinguisher; 3. After the agent picks up the vehicle, the owner needs to sign the pickup confirmation form; 4. The agent will drive the vehicle to the designated inspection center for the inspection; 5. After the inspection is completed, the agent will return the vehicle to the specified location and hand over the relevant documents to the owner.

How to Use the Auto Hold Function in the Vezel?

The method to use the auto hold function in the Vezel: Press the brake hold button to activate the function. While driving, pressing the brake pedal firmly will automatically engage the parking brake, and lightly pressing the accelerator pedal will release it. Auto hold refers to an automatic braking function. Once activated, for example, when stopping at a traffic light, it eliminates the need to manually engage the parking brake or electronic parking brake, simplifying operations. For automatic transmission models, it also avoids frequent switching between D to N or D to P. The Vezel is the first SUV under GAC Honda, developed on Honda's all-new vehicle platform. With five disruptive highlights—diamond-like versatile appearance, ultra-dynamic all-around driving control, aviation-style dream cockpit, versatile flexible space, and humanized intelligent configurations—it completely breaks traditions and subverts conventions, offering consumers an unprecedented trendsetting experience.

How to Solve Fuel Injector Failure?

If the fuel injector failure is caused by the needle valve being clogged with dirt, the injector should be disassembled, cleaned, inspected, and readjusted. Due to the continuous scouring of high-pressure fuel flow, the injection hole of the needle valve will gradually enlarge, leading to a drop in injection pressure. You can place a steel ball with a diameter of 4mm to 5mm at the hole end and gently tap it with a hammer to cause local plastic deformation of the hole, thereby reducing its diameter. For multi-hole direct injection injectors, which have numerous small holes, only a punch made of high-speed steel can be used to lightly tap the hole end. If the injector still fails to meet standards after adjustment, the needle valve assembly should be replaced. The frequent reciprocating motion of the needle valve can cause the end face of the needle valve body to gradually form a pit over time, increasing the needle valve lift and affecting the injector's normal operation. The needle valve body can be clamped on a grinding machine to regrind this end face, followed by fine polishing on a glass plate with fine abrasive paste.

Which gear should an automatic transmission be in when stopping at a red light?

When stopping at a red light with an automatic transmission, the specific gear to use depends on the duration of the red light. The gear selection options are as follows: 1. If the red light is less than 30 seconds, it is recommended that the driver simply keep their foot on the brake; 2. If the red light lasts between 30 seconds and 1 minute, the driver should shift to N (Neutral) gear and engage the handbrake; 3. For red lights longer than one minute, it is advisable to shift directly to P (Park) gear and engage the handbrake. Apart from waiting at traffic lights, automatic transmission vehicles may also need to be parked with the engine off or left idling for extended periods. In such cases, the gear should be shifted to P (Park) because engaging P gear causes the transmission's parking pawl to lock into the parking gear, securing the vehicle's drivetrain. The correct parking procedure is: first, press the brake pedal and shift to N (Neutral) gear, then engage the handbrake and release the brake pedal. Once the vehicle is completely stationary, shift to P (Park) gear.
