Excessive transmission temperature in the Envision may be caused by clutch slippage, thermostat sticking, or engine and coolant overheating. Engine and Coolant Overheating: Prolonged or overloaded engine operation can raise the coolant temperature, affecting transmission cooling. Additionally, insufficient coolant in the radiator reduces the cooling system's efficiency, leading to transmission overheating. Transmission Clutch Slippage: Clutch slippage generates additional heat, increasing transmission temperature and degrading transmission oil quality, which accelerates transmission wear. Thermostat Sticking: If the transmission thermostat sticks, transmission oil cannot circulate into the cooling system, preventing heat dissipation.

What does an exclamation mark inside a bracket indicate as a warning light?

An exclamation mark inside a bracket is the brake system warning light, indicating a malfunction in the braking system that requires immediate inspection and repair. The automotive braking system refers to a series of specialized devices that apply a certain force to specific parts of the vehicle to enforce braking. Reasons for the illumination of the brake system warning light include: 1. Severe wear of brake pads; 2. Low brake fluid level; 3. Abnormalities in the braking system; 4. Failure of the parking brake. The functions of the automotive braking system are: 1. Ensuring the vehicle decelerates or stops as required by the driver; 2. Ensuring the vehicle is reliably parked; 3. Safeguarding the safety of the vehicle and the driver.

When should the Touran L have its engine oil changed?

The engine oil replacement cycle for the Touran L is every 5,000 kilometers or three months. These two maintenance indicators should be determined based on the vehicle's usage conditions, whichever comes first. Since the Touran is equipped with a turbocharged engine, it is recommended to use 5W-30 full synthetic oil, which provides relatively better performance and a longer oil change interval. The method for changing the engine oil is as follows: 1. Run the engine until it reaches operating temperature. Then use a jack to lift the vehicle, engage the handbrake, and secure the front wheels with wooden wedges. 2. Place an old oil container under the oil pan, locate the oil pan drain plug, and slowly loosen it, being careful not to come into contact with the hot oil. Allow the oil to drain for a while. Inspect the drain plug, then reinstall it, ensuring not to overtighten it to avoid damaging the oil pan. 3. Move the oil container under the oil filter, use an oil filter wrench to loosen the filter, and remove it by hand. 4. Apply new oil to the gasket of the new filter. 5. Pour the new oil into the oil pan. A funnel can be used to prevent spilling oil on the engine exterior. Check for leaks under the engine. If there are no leaks, lower the vehicle, check the oil dipstick, and start the engine. After starting, the indicator light on the dashboard should turn off immediately. Finally, turn off the engine and recheck the oil level to complete the process.

What does the dashboard message 'Check Emission System' mean?

The dashboard displaying 'Check Emission System' indicates a fault in the exhaust system that requires inspection. Causes of emission system failure include: 1. Excessive spark plug gap; 2. Incorrect resistance value in distributor wires; 3. Malfunction of oxygen sensor or carbon canister solenoid valve; 4. Excessive carbon buildup in the throttle or engine interior. Hazards of emission system failure are: 1. Leads to excessive carbon accumulation; 2. Compromises driving safety and reduces engine lifespan; 3. Causes engine overheating, leading to sintering or detachment of the catalytic converter substrate and increased exhaust resistance; 4. Exceeds harmful emission standards.

What kind of engine oil is suitable for Haval H6?

Haval H6 is suitable for fully synthetic engine oil. The functions of engine oil are: 1. To separate the relatively sliding parts' surfaces, thereby reducing wear; 2. To bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine; 3. To circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of parts through the flow of lubricating oil. Precautions for changing car engine oil: 1. Drain the oil when it is hot for better fluidity; 2. Fill to the mark on the dipstick; 3. Choose the oil product based on driving environment, driving frequency, and the requirements of the vehicle's engine itself.
