How to Determine a Car's Year from Its Windows?

Car windows have the year of manufacture marked on them, represented by numbers. There will be a series of small black dots either before or after these numbers, indicating the month the glass was produced. Typically, there is a code at the bottom left or right corner of the car window. The last or second-to-last row contains a number and several small black dots, which represent the production date of the glass. The number signifies the production year of the glass, representing the last digit of the year, while the small black dots indicate the production month. Some glass has the dots before the number, and some have them after. If the dots are before the number, subtract the number of dots from 7; if the dots are after the number, subtract the number of dots from 13. The result is the production month of the glass.

What are the functions of the front oxygen sensor and rear oxygen sensor?

The functions of the front oxygen sensor and rear oxygen sensor: The front oxygen sensor detects the oxygen concentration in the engine exhaust and provides this information to the ECU in the form of an electrical signal. The ECU then performs closed-loop control of the fuel injection quantity based on the oxygen concentration information in the exhaust. If a high oxygen concentration is detected in the exhaust, it indicates that the engine's air-fuel mixture is too lean; whereas if a low oxygen concentration is detected, it indicates that the mixture is too rich. The rear oxygen sensor primarily detects the oxygen concentration in the exhaust after it has been purified by the three-way catalytic converter. If the data detected by the front and rear oxygen sensors are the same, it indicates that the three-way catalytic converter has failed. Oxygen sensors are installed on the engine exhaust pipe, with the three-way catalytic converter as the boundary: the sensor before the converter is the front oxygen sensor, and the one after is the rear oxygen sensor.

What does the M gear in an automatic transmission car mean?

Automatic transmission car M gear is the manual mode of the manual-automatic transmission. When the car is shifted to M gear, the car automatically switches to manual transmission, which means it operates like a manual transmission car, requiring downshifting at low speeds and upshifting at high speeds. Moreover, the M gear can be directly switched from the D gear without the need to stop for shifting. Situations where manual mode M gear can be used: 1. When climbing long and steep slopes, manual mode can be set to 1st gear to limit the car to low gear driving, avoiding frequent gear shifts like in automatic D gear, making climbing more powerful and protecting the transmission; 2. When descending long slopes, driving in low gear can help control the speed without constantly pressing the brakes; 3. When accelerating to overtake, switching to manual mode and downshifting first can utilize the high torque of low gears for instant acceleration, completing the overtaking action more quickly.

What to Do When the Dashboard Thermometer Light Comes On?

The dashboard thermometer light coming on indicates that the engine coolant temperature is too high. It is recommended to stop the vehicle and check whether there is water in the radiator, and you should promptly go to a 4S shop for inspection and repair. The coolant temperature indicator mainly displays the temperature of the coolant inside the engine. It lights up for a few seconds only during the vehicle's self-check and remains off under normal circumstances. What maintenance workers often refer to as "engine boiling" means that the coolant temperature has exceeded the specified value. In this case, you should immediately stop driving and proceed with repairs. The thermometer light coming on indicates that the coolant temperature is too high, and special attention must be paid to not continue driving. You must go for maintenance and inspection; otherwise, it can cause significant damage to the engine. The oil pressure indicator is used to display the oil pressure status inside the engine.

What Causes Abnormal Wheel Pressure?

Abnormal wheel pressure is indicated by the tire pressure monitoring light illuminating due to prolonged driving with low tire pressure. This situation typically occurs when: a tire's pressure is too low, high-speed operation increases tire temperature, subsequently causing tire pressure to rise. In such cases, it is advisable to stop and rest promptly or replace the tire with a spare one. The normal range for car tire pressure is between 230 to 250kpa. Tire pressure standards also vary depending on the type of tire and the vehicle model, as different models have varying weights, heights, and tire sizes, thus requiring different tire pressures. Standard tires have a recommended pressure of 240kpa to 250kpa, while reinforced tires should be inflated to 280kpa to 290kpa.

Where is the cigarette lighter fuse for the Roewe i6 located?

Roewe i6 cigarette lighter fuse is located at the back of the dashboard fuse box in the cabin, generally rated at 20A. Typically, the cigarette lighter is mainly used in places where open flames are prohibited. Besides providing a means to light cigarettes, the car cigarette lighter can also be equipped with a vehicle inverter, which can convert the car's 12V, 24V, or 48V DC power into 220V 50Hz AC power for use with ordinary electrical appliances. The Roewe i6 is the first internet-connected sedan under the Roewe brand. In terms of body dimensions, the Roewe i6 measures 4671mm in length, 1835mm in width, and 1464mm in height, with a wheelbase of 2715mm.
