'Ma' is an imperial unit of length, where one 'ma' is approximately equal to 0.9144 meters, or 0.0009144 kilometers. The related introduction is as follows: 1. Origin: A speed of 40 'ma' equals 64 kilometers per hour. The common expression of speed in 'ma' originates from the speed unit 'mile.' One mile per hour is approximately equal to 1.6 kilometers per hour when converted to the metric system. 2. Universal metric system: The internationally accepted metric system means that the commonly mentioned speed of 100 'ma' equals 100 kilometers per hour. When the British say 100 miles, it equals 160 kilometers per hour. In fact, 'mile' refers to 'Mile,' where 1 mile = 1.6 kilometers. Therefore, precisely speaking, 40 miles equal 64 kilometers per hour.

What are the steps to turn on the heating in an older Passat model?

The steps to turn on the heating in an older Passat model are: start the car, turn on the air conditioning, switch to heating mode, and adjust the air vents once the air starts flowing. The heating system relies on the heat generated by the engine after it starts working. A small fan in the engine compartment blows the heat collected from the engine's cooling system into the car. The exterior changes in the older Passat model are mainly reflected in minor details, such as the omission of chrome trim on the side windows and around the body, the use of regular glass throughout the car, unpainted door handles, and smaller wheel sizes. In terms of interior features, leather seats remain standard, the front seats are manually adjustable, and the central armrest in the rear seats is omitted.

Where is the oxygen sensor located on the old Jetta?

The old Jetta has one oxygen sensor at the position where the exhaust pipe exits the engine and another behind the three-way catalytic converter, which are referred to as the front and rear oxygen sensors. The oxygen sensor primarily detects the oxygen content in the exhaust, and the ECU adjusts the fuel injection based on the data it transmits. There is no difference in structure or working principle between the front and rear oxygen sensors. The Jetta is a joint venture of the German Volkswagen Group in China and is a car brand under FAW-Volkswagen Automotive Co., Ltd. Its first product, the Jetta, was launched in Europe in 1979. Structurally, the Jetta is essentially a Golf with a trunk added to the rear, making it a derivative model of the Golf.

Where is the trunk switch on the old Jetta?

The trunk switch on the old Jetta model is a contact point. There is a pressable area on the left side of the door lock position where the lid lifts up, which serves as the trunk switch. For the new Jetta models, the trunk is generally opened with the key, and some have a trunk release switch on the center console. Jetta is an automobile brand of Volkswagen AG in Germany, and it was launched in Europe in 1979. Structurally speaking, the Jetta, including the later Vento and Bora models, are essentially Golfs with an added trunk at the rear. The Jetta can be considered a derivative of the Golf. In China, the Jetta was the first to adopt the world's advanced 5-valve multi-point electronic fuel injection engine, and with its unique product design performance and comprehensive safety technology equipment, it formed a distinctive product personality for the Jetta series of sedans.

How Often Should Tire Rotation Be Performed?

Tire rotation does not have a fixed interval, but for safety reasons, it is recommended to perform it every 20,000 kilometers. Below are the requirements for tire rotation: 1. For unidirectional tread tires, avoid X-pattern cross rotation and instead use the H-pattern rotation method. 2. During rotation, new tires should be placed on the drive wheels. If the tread depth is less than 1.6mm, replace the tires and perform a wheel alignment instead of rotating to extend their lifespan. 3. The tires being rotated must be of the same size, specification, and tread pattern. Below are the precautions after tire rotation: 1. Rotated tires must undergo dynamic balancing before installation. Dynamic balancing eliminates tire bounce, which is crucial at high speeds; otherwise, it may lead to abnormal wear, shaking, or instability. 2. After rotation, it is advisable to perform a wheel alignment to adjust the toe-in and camber angles of the front and rear wheels.
