What does the ECO display on the car dashboard mean?

When the ECO indicator light on the dashboard illuminates, it indicates that the vehicle's economy mode has been activated. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the ECO indicator light on the dashboard illuminates, it signifies that the vehicle's economy mode is engaged. ECO mode is categorized into active and non-active types, with the difference being that the active type has its own dedicated button, allowing the driver to choose whether to activate it. When the driver presses the ECO mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active ECO mode does not have a dedicated button. When the dashboard ECO indicator light illuminates, it serves merely as a reminder function. The ECO system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most vehicles employ the active ECO driving mode, meaning they have their own switch button. Therefore, ECO mode can be activated during daily driving. However, it is unnecessary to engage ECO mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of ECO mode but could also impair vehicle performance. Additionally, ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed, causing the ECO mode to deactivate automatically. During idle parking or when in N/P gear or manual mode, ECO mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and ECO mode will not function in such scenarios.

What does it mean when the ABS light is on in a Jetta?

When the ABS light is displayed on a car, it indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may lose control and skid, preventing the driver from slowing down or adjusting the vehicle's trajectory, which poses a significant safety hazard. There are several states in which the ABS light may illuminate, each with different causes and solutions. The details are as follows: State 1: The ABS warning light remains constantly lit (most common). Cause 1: The ABS wheel speed sensor's sensing area is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections in the system wiring or poor contact in the ABS relay, leading to system failure. Solution: Check the wiring connections and reconnect any loose parts. State 2: The ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. As the engine speed increases, the voltage rises, and the ABS indicator light turns off. This may also occur if the ABS system's power supply voltage is too low, such as due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity, inspect the charging system, and verify the power supply (e.g., voltage relay or poor power contact). State 3: The ABS warning light remains lit after the engine starts and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body, poor electrical connection in the valve body's wiring, or a faulty ABS computer. Solution: Loosen and then retighten the grounding screw on the hydraulic valve body, clean the contact surface if necessary, check for enlarged gaps in the connectors, and replace the ABS or ABS/ASR computer if needed. State 4: The ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals. This may also occur due to incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: The ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch or poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, push the brake switch linkage down with your finger, release the brake pedal to complete the self-setting position, or replace the brake light switch.

Do You Need to Wait for the Traffic Light to Make a U-Turn?

When making a U-turn, vehicles must check if there is a U-turn signal light. If there is a U-turn signal light, even if the stop line has not been reached, the U-turn is only allowed after the U-turn signal turns green. If there is no U-turn light at the intersection, pay special attention to the status of the traffic light. If there is no left-turn light and the green light is flashing, you can make a U-turn. If there is a left-turn green light, you must wait until the left-turn green light flashes before making a U-turn; making a U-turn while the straight-through green light is on is not allowed. At some very special intersections, the left-turn light and the main light are inconsistent and will flash alternately. It is also important to note that if the left-turn light is green but the main light is red, U-turns are prohibited. If the gap is marked with a dashed line, the U-turn is not affected by the traffic signal and does not require crossing the pedestrian crossing. There is one situation where you do not need to look at the traffic light: if the vehicle does not need to enter the left-turn lane stop line at the intersection, meaning the U-turn position has not reached the stop line, you can carefully make a U-turn under the premise of ensuring safety. If there are oncoming vehicles, you must yield to them, applying the rule that vehicles on the auxiliary road yield to those on the main road. Never force a U-turn, as it may obstruct the normal driving of oncoming vehicles. Note that U-turns are not allowed on pedestrian crossings. According to Article 49 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China": motor vehicles are not allowed to make U-turns at locations with no U-turn or no left-turn signs or markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or other dangerous sections of the road. If you need to cross the pedestrian crossing to make a U-turn, you must yield to pedestrians: Pedestrians walking on the right side of the pedestrian crossing have not reached the centerline of the road. Vehicles driving on the left side of the road should slow down and proceed on the basis of ensuring safety, allowing pedestrians to pass. Pedestrians waiting outside the boundary line between the motorized lane and the non-motorized lane. If they have not entered the road, the vehicle should slow down and proceed on the basis of ensuring safety, allowing pedestrians to pass. If pedestrians cross the boundary line between the lane and the non-lane area, vehicles passing without stopping are committing a violation and should be penalized. After pedestrians enter the motorized lane (Lane A) along the pedestrian crossing, vehicles in Lane B should slow down and proceed on the basis of ensuring safety, allowing pedestrians to pass. If vehicles in Lane A pass without stopping, it is a violation and should be penalized. Pedestrians waiting at the centerline of the road without entering the motorized lane. Vehicles passing without stopping are committing a violation and should be penalized. Pedestrians crossing the centerline of the road and entering the lane. Vehicles passing without stopping are committing a violation and should be penalized. If the road is divided by a green belt in the middle, and pedestrians are waiting in the parking area in the middle of the road, vehicles must slow down and proceed on the basis of ensuring safety, allowing pedestrians to pass. Situations where U-turns are allowed: If there is a U-turn sign at the intersection: if there is a clear U-turn sign at the intersection, U-turns are allowed. If there is a U-turn signal light, follow the signal light's instructions. If there is no signal light, make the U-turn based on the specific situation, ensuring it does not hinder other vehicles or pedestrians. If there is no explicit prohibition of U-turns or left turns at the intersection: if there is no explicit prohibition of U-turns, U-turns are allowed. Here, "no explicit prohibition of U-turns" means that as long as there are no "no U-turn signs," "no left-turn signs," or solid lines in the middle of the road, you can confidently make a U-turn. U-turns are also allowed on yellow grid lines: yellow grid lines are actually no-parking grid lines marked at intersections prone to temporary parking congestion, important unit entrances, and other locations where they are needed. Any vehicle stopping on the no-parking grid line (including waiting for traffic lights) is a violation. Although vehicles cannot stop in the yellow grid line area, U-turns are allowed there. As long as there is no central road barrier, the yellow grid line is equivalent to "U-turns allowed." If there is a U-turn signal light at the intersection: this is easy to understand—if there is a U-turn signal light, you must wait for the green light to make a U-turn. If "no left turn" and "U-turn allowed" signs appear simultaneously: U-turns are allowed, but left turns are prohibited. However, "no U-turn" is not equivalent to "no left turn." Things to note when making a U-turn at an intersection: Observe the road markings. If they are solid lines, U-turns are not allowed under any circumstances. Continue driving forward to find a suitable location for a U-turn. If there is a "no left turn" sign ahead, even if there is no mention of prohibiting U-turns, U-turns are not allowed at this intersection because the actions of left turns and U-turns are very similar, and U-turns always involve a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not allowed at this intersection. When making a U-turn, always yield to straight-moving vehicles and only proceed if it does not interfere with their normal driving. Otherwise, you will bear full responsibility for any accidents. Generally, near the intersection stop line, lanes are marked with guiding arrows for vehicles to choose their lanes. The leftmost lane is not always marked with a left-turn arrow. On some roads, if there is a straight arrow, even if there are no explicit prohibitions like "no U-turn," U-turns are not allowed.
