What is the actual fuel consumption of the Peugeot 408 1.6t?

The combined fuel consumption of the Peugeot 408 1.6t is 5.8L/100km. There are currently three models of the Peugeot 408 1.6t on sale: the 10th Anniversary Edition, the 10th Anniversary Premium Edition, and the 10th Anniversary Ultimate Edition, all with a combined fuel consumption of 5.8L/100km. The above figures are based on the NEDC combined fuel consumption, which is the data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 7.0-9.2L/100km. Specific factors affecting a car's fuel consumption are as follows: Vehicle weight: Larger and heavier cars tend to consume more fuel. Generally, a small family car with a 1.6L engine weighs around 1.2 tons and has a fuel consumption of approximately 7.5 liters (calculated under full load), while an SUV weighing around 1.5 tons consumes about 8.5 liters. Different weights result in varying fuel consumption. Drag coefficient: Higher drag increases fuel consumption during driving. Cars with better aerodynamics have lower drag coefficients, leading to reduced fuel consumption. Economical RPM: During driving, the engine has an optimal torque output point. Maintaining the car's speed within this range significantly reduces fuel consumption. Typically, small-displacement cars achieve this at around 70 km/h, while larger-displacement cars reach it at about 100 km/h. Staying within this economical RPM range ensures minimal fuel consumption. Driving style: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before stopping at traffic lights can increase fuel consumption.

Why is the ABS light on in the Buick Excelle?

When the car displays ABS, it means there is a fault 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, as detailed below: State 1: ABS warning light stays on (most common). Cause 1: The ABS speed sensor's sensing part 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 speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt off the speed sensor and adjust the gap between the speed sensor and the signal ring to restore normal function. Cause 2: Loose connections between system lines or poor contact in the ABS relay can cause signal issues, leading to system failure. Solution: Check the line 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 may drop 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's 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; poor contact in the ABS hydraulic valve body wiring connector; ABS computer failure. Solution: Loosen and then retighten the grounding screw of the hydraulic valve body; clean 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: During high-speed driving, the ABS computer detects a significant difference between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the sticker near the fuel cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact in the brake light. Solution: Start the engine, press the brake pedal, push the brake switch linkage down with your finger, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary.

What are the reasons for the engine warning light in Haval M6?

There are mainly 7 reasons for the engine warning light in Haval H6: Sensor failure: The sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to illuminate. Fuel quality issues: If fuel and engine oil are not added according to the manufacturer's requirements, it may cause engine wear and trigger the warning light. Poor combustion of the air-fuel mixture: Poor combustion can lead to engine carbon deposits or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Spark plug failure, ignition coil failure, fuel pump failure, or fuel line blockage can all cause poor combustion of the air-fuel mixture. Turbocharging issues: The intake turbocharging pipeline and turbocharger can also cause the engine warning light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, high oil consumption, reduced power, metal noises, or blue/black smoke from the exhaust. Intake issues: If the car's intake system has problems, it may lead to engine pipeline blockages, and in severe cases, trigger the engine warning light. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust issues: Exhaust system failures can also cause the engine warning light to illuminate. The rear oxygen sensor, catalytic converter, exhaust camshaft, and bearing failures are common causes of exhaust problems, with the catalytic converter being the most frequent. Using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system failures can easily cause catalytic converter issues. Anti-theft system failure: If the car's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine ECU, the anti-theft system can prevent the engine from operating normally and trigger the warning light. If the engine warning light is on, follow these steps: First, check if the engine is running normally, such as whether there is shaking or black smoke. If so, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can start, turn it off for 5-10 minutes, then press the start button without stepping on the brake, or turn the key halfway to the "ON" position without pressing the clutch. The car will enter self-check mode after powering on. Wait for 5-10 seconds and observe whether the warning light turns off. If the warning light remains on, visit a service station as soon as possible. The service station can use a portable diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.

How many points are deducted for the car body brushing the line in the parallel parking test of Subject 2?

In theory, brushing the line with the car body in Subject 2 does not result in point deduction. Note that brushing the line is different from crossing the line—crossing the line will definitely deduct 100 points. The specialized evaluation criteria for Subject 2 only specify that the car body must not cross the line, and there is no mention of brushing the line. Generally, as long as the car body does not cross the line, there is no significant impact, but the final judgment depends on the examination system. The point deduction standards for parallel parking in Subject 2 are as follows: 1. Failing if the car body crosses the line after stopping in the parking space. 2. Deducting 5 points for stopping midway. 3. Deducting 10 points for the tires touching the lane boundary line while driving. 4. Deducting 10 points for not turning on the left turn signal when starting. 5. Deducting 10 points for not turning on the right turn signal when reversing. 6. Failing if the car is not parked inside the parking space. 7. Failing if the test is not completed within the specified time. 8. Deducting 10 points each time the car body touches the parking space boundary line while driving. Key points for reversing into the parking space: 1. Reversing from the starting point into the parking space: - After getting into the car, the driver should adjust the seat and rearview mirrors and fasten the seatbelt. - Shift to reverse gear, release the parking brake lever, and start reversing at idle speed. - Observe the parking space through the right rear window. - When the black edge of the right rear window aligns with the right boundary line of the parking space, turn the steering wheel to the right at a steady speed until it reaches the limit position. - After the car enters the parking space, the driver should look back at the left rearview mirror. When the entire left boundary line of the parking space is visible, immediately straighten the steering wheel. - When the left door handle is level with the bottom line of the parking space in the left rearview mirror, stop immediately. 2. Driving from the parking space to the return point: - Shift to first gear and drive out of the parking space. - When the hood approaches the road boundary line, turn the steering wheel to the left until it reaches the limit position. - Stop when the car is straight. 3. Reversing from the return point into the parking space: - Shift to reverse gear and keep the steering wheel turned to the left at the limit position while reversing. - The driver should observe the left rearview mirror and adjust the direction to guide the rear of the car into the parking space. - After the car enters the parking space, observe the right rearview mirror. When the entire right boundary line of the parking space is visible, immediately straighten the steering wheel. - Then, look back at the left rearview mirror. When the left door handle is level with the bottom line of the parking space, stop immediately. 4. Driving from the parking space back to the starting point: - Shift to first gear and drive out of the parking space. - When the hood approaches the road boundary line, turn the steering wheel to the right until it reaches the limit position. - Stop when the car is straight.

What is the normal tire pressure for a Haval H2?

The normal tire pressure range for the Haval H2 is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and reduced by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. The tire pressure monitoring system in the Great Wall Haval H2 can be checked via the function button on the steering wheel (the up and down paging buttons on the left side of the steering wheel). The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving and alerts the driver to any leaks or low pressure to ensure driving safety. Generally, a tire pressure above 2.8bar is considered too high, and a tire pressure below 2.0bar is considered too low. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread of the tire, shortening its lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing elasticity and increasing the load on the vehicle while driving. Hazards of insufficient tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; weakens the function of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), it is generally due to one of the following three reasons: Abnormal tire pressure. The system typically alerts when the pressure is below 1.8bar or above 3.0bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset. After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the indicator light to remain on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor. The sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged during driving, the tire pressure warning light will illuminate. In such cases, the only solution is to replace the sensor with a new one.
