What Causes Car Shaking Between 40-50 MPH?

Can the Classic Sylphy produce a sound when locking the car?

The Classic Sylphy can be set to produce a sound or remain silent when locking the car. The setting method involves pressing both the unlock and lock buttons on the remote control simultaneously for more than three seconds to toggle between the two modes. When pulling the car door, be sure to do so gently and avoid using excessive force to prevent damage to the door switch. Below is an introduction to the Classic Sylphy: 1. The Classic Sylphy is a compact family sedan under the Nissan brand, equipped with a continuously variable transmission (CVT), good safety performance, and smart features. It adopts a front MacPherson strut independent suspension and a rear torsion beam non-independent suspension. 2. The Classic Sylphy's engine model is HR16, available in 1.6L and 1.8L CVVT engine options.

How to Check the National Emission Standard of a Vehicle?

Methods to check the national emission standard of a vehicle: 1. Check the vehicle's environmental protection label; 2. Look at the vehicle's factory certificate or vehicle conformity certificate; 3. Log in to the Motor Vehicle Environmental Protection Network public inquiry platform; 4. Differentiate based on the vehicle's manufacturing year. Vehicle emission standards are divided into: 1. Vehicles with a total mass less than or equal to 3.5 tons equipped with spark-ignition engines or compression-ignition engines; 2. Vehicles with a total mass greater than 3.5 tons equipped with spark-ignition engines. Additional information: Vehicle emissions refer to harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and soot discharged from exhaust.

Where is the car air conditioning evaporator located?

The car air conditioning evaporator is installed inside the evaporator box, which is located behind the dashboard on the passenger side, usually behind the cabin air filter. The car air conditioning refrigeration system consists of components such as the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. Below is relevant information: 1. The function of the evaporator is to serve as the place where the refrigerant changes from liquid to gas (i.e., evaporation) to absorb heat. The car air conditioning refrigeration system includes components like the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. The evaporator is a device that achieves heat exchange between the outside air and the substance inside the pipes by covering a row of coiled pipes with thin metal sheets for heat dissipation. 2. The evaporator is the heat exchange container of the car air conditioning system. The source evaporator is hidden inside the evaporator box and is generally not easily visible. Under normal circumstances, the surface temperature of the evaporator is very low, but it only forms a lot of condensation without frosting or freezing. Its principle is similar to that of the engine's radiator (the only difference is that the water in the radiator remains in liquid form), so it is often installed at the front of the car, together with the radiator, to enjoy the cool breeze from the front.

Does Airbag Deployment Count as a Major Accident?

Airbag deployment does not necessarily count as a major accident, as sometimes airbags can deploy even in minor collisions. Therefore, using airbag deployment as a criterion for determining the severity of an accident is not accurate. Factors Triggering Airbag Deployment: Whether an airbag deploys depends on the direction of the collision and the magnitude of the vehicle's acceleration caused by the impact, not the extent of vehicle damage. Thus, rear-end collisions, rollovers, or severe damage may not necessarily trigger airbag deployment. Different manufacturers set varying conditions for airbag deployment. Typically, frontal airbags deploy when the vehicle speed exceeds 25 km/h and a severe impact occurs within a ±30-degree angle range. Side airbags deploy when a severe impact occurs within a ±60-degree angle range on the side of the vehicle. Precautions for Airbag Use: If a car is equipped with dual front airbags, children should not sit in the front seat or have child seats installed there. Normally, when the ignition switch is turned to the "ACC" or "ON" position, the system performs a self-check on the airbags. If the airbag warning light on the dashboard remains lit, it indicates a fault in the airbag system, which should be repaired. Avoid hanging decorations on the front windshield or rearview mirror, as they may be propelled toward occupants during airbag deployment, causing unnecessary injuries.

What to Do When the Jetta Speed Sensor Malfunctions?

When the Jetta engine speed sensor malfunctions, it is necessary to carefully check the sensor's wiring and whether the engine control unit (ECU) has failed. A damaged engine speed sensor (crankshaft position sensor) can result in the vehicle having no high-voltage spark, making it impossible to start the car normally, and thus requires replacement. Below is an introduction to the engine speed sensor: 1. The engine speed sensor is an inductive sensor that captures the engine speed and the precise angular position of the crankshaft (input system). 2. A separate signal wheel for the engine speed sensor is installed on the flywheel. The signal wheel is designed as a toothed wheel divided into 60 segments. Each time the signal wheel passes the sensor, it generates an alternating voltage whose frequency varies with the speed, and this frequency corresponds to the engine speed.

How to Use Cruise Control?

To use the car's cruise control: 1. Press the power button to activate the system, and the cruise control indicator light on the dashboard will illuminate; 2. Accelerate to the desired speed, then press the SET button to lock the speed at the current rate; 3. Press the RES (+) button to increase speed from the current setting, or the SET (-) button to decrease speed. Cruise control is a system that allows the driver to maintain a constant preset speed without operating the accelerator pedal. Conditions for using the car's cruise control system include: 1. It is prohibited in rainy or snowy/icy weather; 2. It should not be used when there is heavy traffic; 3. It can be used on highways or fully enclosed roads.
