Does the Study and Deduction Policy Affect the Driver's License?

After participating in the Study and Deduction program, you can continue to accumulate demerit points, as it only reduces the existing points on your driver's license and does not affect its usage. The Study and Deduction policy allows motor vehicle drivers to reduce the demerit points for traffic violations by receiving education. Within one scoring cycle, a maximum of 6 points can be deducted. There are three ways to participate in the Study and Deduction program: 1) Online study (accumulating at least 30 minutes over 3 days) and passing the exam can reduce 1 point; 2) Attending on-site study sessions (each session lasting at least 1 hour) and passing the exam can reduce 2 points; 3) Participating in traffic safety public welfare activities (1 hour per session) can reduce 1 point. The Study and Deduction program has a dedicated question bank, covering topics such as safe driving knowledge, highway driving knowledge, civilized driving knowledge, driving psychology, common traffic signs, road markings, and traffic police hand signals. The Study and Deduction exam consists of 20 questions, with a perfect score of 100 points. A score of 90 or higher is required to pass. Accumulating 3 wrong answers will result in exam failure.

How Long Does It Take for a Submerged Car Chassis to Be Affected?

When a car chassis is submerged to the point of accumulating water, it can be affected immediately, as there is no fixed time frame due to varying drainage efficiency among vehicles. Generally, water entering the chassis does not cause significant issues, but if the water level rises above half of the tire, it is crucial to brake first upon exiting the water to expel the moisture and prevent affecting braking performance. Below are the methods to handle water entering the chassis: 1. Accumulated water in the chassis: While there is always a possibility of water entering the chassis, cars are designed to drain it naturally. However, if water accumulates, the chassis must be cleaned. During the cleaning process, it is essential to pay attention to rust prevention, as stagnant water is highly likely to cause rust. 2. Maintenance: The simplest protective measure is to apply a layer of waterproof coating directly onto the chassis, effectively blocking external water from entering the interior. During this maintenance, it is important to check whether the chassis's internal self-draining system is functioning properly. If not, maintenance should be performed accordingly.

Is it okay to engage the P gear without pulling the handbrake?

Whether to pull the handbrake when engaging the P gear depends on the terrain: 1. On relatively flat ground, you can engage the P gear without pulling the handbrake; 2. On uneven ground, you need to pull the handbrake after engaging the P gear. The car gears include: 1. P gear is the parking gear and starting gear; 2. R gear is the reverse gear; 3. N gear is the neutral gear; 4. D gear is the forward gear, also known as the drive gear; 5. L gear is the low-speed gear; 6. S gear is the sport mode; 7. OD gear is the overdrive gear. The steps for parking a car are: 1. Press the brake to stop; 2. Shift the gear from D to N; 3. Pull the handbrake and turn off the engine; 4. Release the foot brake, but do not turn off the power, to ensure the car is completely stopped under the handbrake; 5. Press the foot brake and shift the gear from N to P; 6. Release the foot brake; 7. Turn the key back, turn off the power, and remove the key.

What does ECO mean in automatic transmission cars?

ECO in automatic transmission cars refers to the economic driving mode. ECO is an English abbreviation formed by combining 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 indicates that the vehicle's economic mode has been activated. Eco mode is categorized into active and non-active types. The difference lies in the fact 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 Eco indicator light on the dashboard 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 cars employ the active Eco driving mode, meaning they have their own switch button. Therefore, during daily driving, we can activate the Eco mode. However, it is unnecessary to activate 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 also compromise the vehicle's power performance. Additionally, the 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 automatically deactivate. During idle parking or when in N/P gear or manual mode, the 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 the Eco mode will not function under these conditions.

What Causes the ABS Light to Illuminate in a Polo?

There are various states in which the ABS light illuminates, with different causes and solutions for each state, as detailed below: State 1: ABS warning light remains constantly on (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 off the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Loose connections between system wires or poor contact in the ABS relay lead to signal issues, causing system failure. Solution: Check wire connections and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off during acceleration. 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 light turns off. This may also occur if the ABS system power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light remains on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact in the ABS hydraulic valve body; loose wiring connections in the ABS hydraulic valve body; ABS computer malfunction. Solution: Loosen and then retighten the grounding screw on the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: At high speeds, the ABS computer detects a significant discrepancy between rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's specified tire and wheel rim dimensions, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: With the engine running, press the brake pedal, push the brake switch linkage down fully with a finger, then release the pedal to complete self-positioning; replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, preventing the driver from slowing down or adjusting the vehicle's path, posing significant safety risks.
