Here are the reasons for the high fuel consumption of the 1.5L Buick Excelle: Clogged fuel system: Excessive carbon deposits causing fuel line blockage, leading to increased fuel consumption. Brake abnormalities: Brake pads not retracting properly, resulting in the vehicle constantly driving in a braking state. Spark plug malfunction: Generally, spark plugs need replacement after 20,000-30,000 kilometers. If you notice high fuel consumption, check if the spark plugs have abnormal ignition. Dirty air filter: Vehicle maintenance requires timely replacement of the air filter, otherwise it may cause poor air intake and increased fuel consumption.

Where is the turn signal relay located in the Geely Emgrand?

Geely Emgrand turn signal relay is located on the left side in front of the driver. Relay box: Expanding control range: For example, multi-contact relays can simultaneously switch, disconnect, or connect multiple circuits in different contact group configurations when the control signal reaches a certain value. Power amplification: For example, sensitive relays and intermediate relays can control high-power circuits with very small control inputs. Signal integration: For example, when multiple control signals are input into multi-winding relays in specified forms, they can achieve predetermined control effects through comparison and integration.

What to Do If the ETC Card Is Lost?

If the ETC card is lost, it is necessary to apply for a replacement in a timely manner. The vehicle owner needs to bring the original ID card and a copy to the bank counter to handle the card change or replacement. To apply for a replacement, fill out an ETC service application form at the bank counter and report the loss of the ETC function, which will take effect within 24 hours from the time of acceptance. After receiving the new card, go to the designated bank outlet to activate the ETC function. The ETC function can be automatically used within 5 working days. When using ETC, please note that the transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of more than 10 meters to prevent automatic payment for the vehicle in front, in case the ETC device of the front vehicle malfunctions or is absent. The recognition speed for ETC lanes is 20km/h. Driving too fast may result in failure to read the vehicle's device information, leading to payment failure. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will cause the electronic tag to become invalid. In such cases, the device can be sent to the bank where the ETC card was issued or to the highway service office for inspection. If the loosening or detachment is not due to human factors, reactivation is sufficient. When using a debit card linked to ETC, insufficient balance may also cause payment failure. Follow the guidance of on-site staff to use the manual MTC lane, paying with cash or by swiping the card. A car windshield that is too thick may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.

Which light is the auto?

auto refers to the automatic headlights. Here are the specific details: 1. Introduction: It controls the automatic turning on or off of the headlights by sensing changes in external light intensity. 2. Function: For the convenience of the driver, the automatic headlights are equipped with a light-sensing control system. When the system detects that the external light intensity is above or below a certain threshold, the car headlights will automatically turn on or off. Here are some additional details about the use of automatic headlights: (1) Simply turn the combination light switch to the auto position to activate the automatic headlight function. When driving at night or entering a tunnel, the headlights will automatically turn on. However, it's important to note that automatic headlights do not adjust between high and low beams. (2) Since automatic headlights rely solely on sunlight sensors to determine the surrounding brightness, they cannot analyze real-time changes in the environment to switch between high and low beams. If you want the automatic headlights to control the high beams, you need to push the combination light switch forward to the high beam position and then turn the knob to the auto position. This way, the high beams will automatically turn on.

What causes the buzzing sound in the MG6 when starting the engine?

MG6's engine buzzing sound during startup is caused by clutch abnormalities. Engine intake pipe leakage: The intake system contains many intake manifolds or various valves. Leakage in these components can allow unwanted gases to enter, resulting in excessively high or low concentrations of the air-fuel mixture in the intake manifold. This ultimately leads to intermittent engine shaking or symptoms of weakness during idling. Fuel system blockage or malfunction: Due to clogged fuel tank vent holes, fuel tank switch, fuel filter, or partial blockage of the fuel line between the fuel tank and carburetor, the engine cannot receive the corresponding amount of fuel during idling. This causes the air-fuel mixture to become lean, resulting in weakened engine power output and idling vibrations.
