What is the actual fuel consumption of the GAC GS4?

The comprehensive fuel consumption of the GAC GS4 is 6.8L/100km. Currently, there are 6 models of the GAC GS4 available for sale: the Automatic Intelligent Flagship Edition, Automatic Intelligent Navigation Edition, DCT Premium Edition, Manual Elite Edition, Manual Comfort Edition, and Automatic Intelligent Technology Edition. All these models have a comprehensive fuel consumption of 6.8L/100km. The above figures are based on the NEDC comprehensive fuel consumption test, which measures fuel consumption under the NEDC test procedure. The actual fuel consumption is higher than this value, around 7.3L. Methods to reduce fuel consumption: Clean engine carbon deposits: Excessive carbon deposits in the engine are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not noticeable, it indicates a high level of carbon deposits in the engine. In such cases, the car must be taken to a 4S shop for professional cleaning of the carbon deposits by technicians. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor monitors the air-fuel ratio of the engine. Once damaged, it can cause an imbalance in the air-fuel ratio, leading to a sudden increase in fuel consumption. If the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gases during driving, and the sensor should be replaced immediately. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If not replaced for a long time, they can become dirty and send incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased carbon deposits in the engine. Check the electronic control unit: Although the engine's electronic control unit is highly reliable, in older vehicles, various faults may inevitably occur.

What Causes the Engine Warning Light to Illuminate on the Dashboard?

The engine warning light may illuminate due to the following 7 main reasons: Sensor malfunction: The sensors involved include those for coolant temperature, crankshaft position, air flow, intake temperature, oxygen levels, etc. When these sensors are damaged, have poor connections, or their signals are interrupted, the vehicle's ECU cannot accurately obtain engine data, triggering the engine warning light. Fuel and oil quality issues: Failure to use the fuel and oil types specified by the manufacturer may cause engine wear, leading to the warning light activation. Poor fuel mixture combustion: This can result in engine carbon buildup or knocking. Once detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as an alert. Causes include faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines. Turbocharger problems: Issues with the intake boost pipes or turbocharger can also trigger the engine light. The most common is turbocharger damage, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake system issues: Problems with the car's intake can lead to engine pipe blockages, potentially causing the warning light to turn on. A dirty or uncleaned air filter is a frequent culprit. Exhaust system problems: Exhaust faults, such as malfunctions in the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings, can activate the engine light. The catalytic converter is most commonly affected, especially when using leaded gasoline or improper oil additives, or after physical damage. Anti-theft system malfunction: If the car's electronic anti-theft system fails or there's a mismatch between the anti-theft controller and the engine ECU, the engine may not operate correctly, and the warning light will illuminate. Steps to address an illuminated engine warning light: First, check if the engine is running normally—look for shaking, black smoke, etc. If abnormalities exist, avoid restarting the engine. Note: Never restart if the light is red. If the engine starts, turn it off and wait 5-10 minutes. Then, without pressing the brake, press the start button once or turn the key halfway to the 'on' position (without engaging the clutch). The car will perform a self-check; observe if the warning light turns off after 5-10 seconds. If the light remains on, visit a service center promptly. Technicians can use diagnostic tools to read fault codes, identify the issue, and perform targeted repairs.

How to adjust the audio system in the 10th-generation Civic?

Click the "HOME" button on the central control screen - select "Audio" - click the "MENU" function key, then choose and enter the sound quality adjustment options. Here are some relevant details about the 10th-generation Civic's audio system: 1. Brand: Honda factory-installed audio. 2. Notes: Pay attention to the host unit's operating parameters, particularly the output power index changes following impedance variations. High-quality amplification equipment will show significant power output increases when impedance drops, sometimes by several times. The amplifier's power rating should exceed the speaker's indicated power. If the amplifier's power is insufficient, prolonged high-power usage may cause burnout, along with poor sound quality and distortion issues.

What do res and set mean?

res and set have the following meanings: 1. res stands for reset: meaning to reset. It is mostly found on the center console and is used to set multimedia functions such as the radio. res has two functions: one is to accelerate after setting the cruise control, and the other is to press RES to restore the previously set speed after temporarily canceling the cruise control. 2. set, the set button: means to set. set also has two functions: one is to decelerate after setting the cruise control, and the other is to press set to set the current speed as the cruising speed after temporarily canceling the cruise control.

How many items are there in the Subject 3 lighting test?

Subject 3 lighting test includes turning on the headlights, low beam, high beam, alternating between high and low beams, width indicator lights, and hazard warning lights. Below is relevant information about the Subject 3 lighting test: 1. Situations requiring alternating between high and low beams: when passing sharp curves or slopes at night, when overtaking vehicles ahead at night, when passing intersections without traffic signals at night, when passing arch bridges or pedestrian crossings at night. 2. Function of high beams: A vehicle's high beams can improve driving visibility and expand the field of view. When driving on roads without streetlights, the visibility range with high beams is significantly greater than with low beams. It is preferable to use high beams on roads with poor lighting conditions.

Is the ETC LCD Screen Always On?

Whether the ETC LCD screen is always on is explained in detail below: 1. Always On Status: The ETC screen normally remains off. 2. ETC (Electronic Toll Collection): Also known as an automatic road charging system, it is a dedicated road tolling method primarily used for toll roads, commonly seen on highways, toll bridges, or tunnels to alleviate urban traffic congestion. 3. Purpose of ETC: Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at toll stations, it utilizes computer networking technology to perform backend settlement processing with banks, achieving the goal of allowing vehicles to pass through toll stations without stopping to pay bridge or road fees.
