Which Turn Signal to Use for Parallel Parking?

Parallel parking requires the use of the right turn signal. Below are detailed instructions on turn signal usage: 1. Left Turn Signal: The left turn signal should be activated in advance when making a left turn, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn. 2. Right Turn Signal: The right turn signal should be activated in advance when making a right turn, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside. 3. Accident Liability: If an accident occurs due to the driver's failure to use the turn signal, there is a high probability that the driver will bear primary or full responsibility for the accident.

What is the Difference Between Major and Minor Maintenance at Tuhu?

Tuhu major maintenance and minor maintenance differ in the following aspects: 1. Basic definitions differ: Minor maintenance refers to routine service items performed at the manufacturer-specified time or mileage intervals to ensure vehicle performance. It primarily includes engine oil and oil filter replacement. Major maintenance refers to conventional services conducted at the manufacturer-recommended intervals, encompassing engine oil, oil filter, air filter, and fuel filter replacements. 2. Intervals differ: Minor maintenance interval: The frequency depends on the effective duration or mileage of the engine oil and oil filter used. Major maintenance interval: Major maintenance builds upon minor maintenance, with these two services alternating. Intervals vary by vehicle brand, subject to manufacturer recommendations. 3. Materials differ: Materials for minor maintenance: Engine oil and oil filter. Materials for major maintenance: Engine oil, oil filter, air cleaner, and fuel filter.

What Causes the Yellow Light on the Tachometer to Illuminate?

The reasons for the yellow light on the tachometer are as follows: 1. If it flashes for a few seconds upon startup and then automatically turns off, it is a normal system check. 2. If the yellow light remains steadily lit, it indicates a malfunction in the vehicle's exhaust system. 3. If it flashes continuously for an extended period, it signifies an engine misfire condition. Here is additional information about the yellow "water tap" light: 1. The yellow "water tap" light is the vehicle's engine (exhaust system) malfunction indicator, alerting the driver to an engine fault. The light features a yellow engine symbol resembling a water tap. 2. When the engine malfunction light illuminates, the cause must be identified and resolved. The light will only turn off after the issue is fixed and the vehicle passes a system check. 3. Numerous factors can trigger the engine malfunction light, including spark plug carbon buildup, sensor failures, or engine cylinder misfires. Prompt diagnosis is crucial to prevent severe engine damage or complete failure. 4. If the engine malfunction light activates, first check the coolant temperature gauge and oil pressure for abnormal readings. If either shows excessively high values, pull over immediately and seek assistance. If both appear normal, proceed cautiously to an auto repair shop for inspection. Regardless of circumstances, always prioritize visiting a professional mechanic as soon as possible when the engine malfunction light appears.

What are the methods to repair scratched car paint?

There are several methods to repair scratched car paint, including touch-up pen repair, spray painting, and computer color matching. For vehicles with shallow scratches, polishing can also be used for quick treatment. Methods to repair scratched car paint: Touch-up pen repair: Apply a touch-up pen with a similar color to the scratched area. This method is relatively simple, not complex in process, but has poor durability. It may wash off after several cleanings and is only suitable for short-term appearance maintenance and emergency repair. Spray painting: Use traditional methods to repair deep scratches, including rust removal and filler application. After drying, sand with water sandpaper repeatedly until smooth, then apply paint. This method affects a larger area of the original paint, takes longer to repair, may have some color difference, and the effect is slightly inferior. Computer color matching: This method uses new techniques, covers a smaller repair area, and, after treatment with special solvents, integrates the new and old paint surfaces seamlessly. It adheres firmly and can be repaired immediately. With proper repair techniques, the touch-up effect is excellent. Use a polishing wheel with polishing enhancer to remove the oxidation layer on the car's surface and smooth out minor scratches. The polishing agent penetrates the paint, causing a restorative reaction that not only removes shallow scratches but also refreshes the paint surface.

Is it normal for the turbocharger impeller to wobble by hand?

It is not normal for the turbocharger impeller to wobble by hand. Additional information is as follows: 1. Introduction: The centrifugal compressor and turbine are combined into one unit, called a turbocharger. The main difference between it and a gas turbine is that this unit does not have a combustion chamber or corresponding system. The turbine operates using the exhaust energy from a reciprocating internal combustion engine, and its centrifugal compressor provides compressed air as the charge for the reciprocating internal combustion engine. 2. Working Principle: The turbocharger uses pressure to drive the pump impeller inside the housing to rotate, thereby driving the intake turbocharger turbine impeller to compress air into the cylinder, thus improving the engine's output power as a control device.

What does EBP mean on large vehicles?

EBP on large vehicles stands for Electronic Parking Brake system. More details about EBP are as follows: 1. Principle of electronic parking brake: The electronic parking brake system replaces traditional mechanical levers and tire cables, substituting the conventional handbrake lever with an electronic parking brake button. It is safer than traditional handbrake levers as the braking effect won't vary with the driver's pulling force, transforming the conventional handbrake lever into an easily accessible button. 2. Application of electronic parking brake: EBP is mainly used in tractors and trucks. The EBP intelligent energy-saving system is equivalent to having three gear selection keys for the engine, allowing free selection based on different road conditions and load capacities to keep the engine operating in the most fuel-efficient range, achieving fuel-saving purposes.
