It is normal for the car malfunction light to disappear after ignition, and the reasons are as follows: 1. After turning on the ignition switch, the vehicle's various system computers will perform a self-check. 2. If no fault is detected in the system after the self-check, the malfunction light for that system will not illuminate after starting the engine. Car malfunction lights can be divided into three types: 1. Indicator type: Used to explain some basic conditions of the vehicle, indicating the current working state of the vehicle, making it easier to understand the various functions and status of the vehicle. (e.g., lighting system indicator, water temperature indicator, fuel level indicator) 2. Prompt type: Used to indicate that the current state of the vehicle is abnormal or the operation is incorrect. (e.g., seat belt reminder light, door open reminder light) 3. Warning type: Indicates that the vehicle has a fault and requires repair. (e.g., engine malfunction light, oil light)

What is the normal water level for a car?

The water level should be between the two lines marked on the reservoir. Below is relevant information about diesel engine coolant systems: 1. Function: To cool the engine by dissipating heat from water. In summer, it's necessary to use summer-grade antifreeze coolant, which has a boiling point around 108°C (higher than water) to prevent overheating. In winter, winter-grade antifreeze should be used to ensure the coolant doesn't freeze outdoors while still providing cooling. High-quality antifreeze can protect down to about -60°C. 2. Cleaning method: First, prepare a cleaning solution with 30kg water, 2.5kg caustic soda, and 0.6kg kerosene, then pour it into the coolant reservoir. Start the diesel engine and let it run at medium speed for about 10 minutes before shutting it off. After 10-12 hours, restart the engine and run at medium speed for another 10 minutes before shutting off and draining the cleaning solution. Add clean coolant water, start the engine, and let it run at medium speed for self-cleaning. Repeat this process 2-3 times to completely remove scale deposits.

Is the new vehicle inspected in the sixth or seventh year?

New vehicles are inspected in the seventh year. Below is a detailed introduction to the annual inspection for seven-seater vehicles: 1. New inspection regulations: Non-commercial passenger cars, including non-commercial sedans, small and micro passenger vehicles, but vans and models with 7 seats or more (such as Odyssey, GL8, Highlander 7-seater, etc.) are not eligible for the exemption policy. New vehicles within 6 years are exempt from on-site inspection, requiring only an application for inspection marks every two years. Eligible private cars registered after September 2012 can enjoy this exemption policy, followed by an annual inspection thereafter. Vehicles aged 6 to 15 years require an annual on-site inspection, while those over 15 years old require a semi-annual on-site inspection. 2. Required documents for inspection: Owner's ID card, original vehicle registration certificate, valid compulsory traffic insurance policy, and proof of vehicle and vessel tax payment (or exemption) for the current year (usually included in the compulsory insurance policy).

What is Brake Pedal Free Play?

Here is the relevant introduction about pedal free play: 1. Introduction to pedal free play: Pedal free play is set to ensure no brake dragging occurs and the brake is fully released. To measure it, place a straightedge between the brake pedal and the cab floor. Press the brake pedal downward by hand until resistance is felt, and record the straightedge reading. Then release the pedal and check the straightedge reading again. The difference between the two readings is the pedal free play. For hydraulic brakes, the pedal free play is generally 15-20mm, and it should be adjusted according to the specified value for the vehicle model. 2. Adjustment: When the free play is inappropriate, loosen the lock nut of the master cylinder push rod, turn the push rod to adjust its length. After adjustment, tighten the lock nut again. The free play of the brake pedal in a Santana sedan refers to the pedal travel when the push rod contacts the master cylinder piston upon pressing the pedal. During inspection, lightly press the pedal by hand and measure the pedal travel until the hand feels resistance. The travel should be ≤45mm. The effective travel when the brake pedal is fully pressed should reach 135mm, and the total travel of the brake pedal should be ≥180mm. If the inspection fails, it can be corrected by adjusting the length of the push rod.
