What to Do If the Car Maintenance Manual Is Lost?

If the car was purchased from an authorized 4S dealership, the purchase information is usually recorded in the manufacturer's connected system. The maintenance manual can be reissued by searching with the vehicle's VIN (Vehicle Identification Number). Here is an introduction to the car maintenance manual: 1. Maintenance Service Manual: It mainly includes maintenance for the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 2. Vehicle Maintenance: It emphasizes "70% maintenance, 30% repair," meaning that during the entire lifespan of the vehicle, regular inspections and periodic maintenance should be carried out to detect and resolve issues early, achieving the goal of maintenance over repair, and even avoiding major repairs throughout the vehicle's life.

How to Master Distance Without a Rear Parking Sensor?

Here are methods to master distance without a rear parking sensor: 1. If the rear object is a car: When the rearview mirror almost obscures the engine hood of the car behind, it indicates the rear of your car is 30-50 cm away. At this point, slow down and prepare to stop. 2. If there's a parallel parked car nearby while reversing: Use this car as a reference. When your side mirrors align with the reference car's side mirrors during slow reversing, it's time to stop. 3. If the rear is a wall: Visually locate a point about 1 meter high on the wall. Slowly reverse until the rear of your car aligns with this point in the rearview mirror, indicating a distance of about 40-50 cm from the wall. Stop at this point. 4. For nighttime: Use brake lights as a guide. Observe the taillight convergence in the side mirrors. Generally, the closer the car is to the wall, the more the light spreads. When the brake lights appear as wide as the car body, it means the rear is close to the wall, and you should stop.

Is it easy to repair a transmission that is leaking oil after being hit by a stone?

Whether a transmission is easy to repair after being hit by a stone and leaking oil depends on the extent of the collision. Here is an introduction to the situation of a transmission leaking oil after being hit by a stone: 1. Check for external oil leaks: Pay special attention to whether there is oil leakage at the front and rear crankshaft oil seals. A broken, damaged, or aged front crankshaft oil seal, or wear on the contact surface between the crankshaft pulley and the oil seal, can cause oil leakage at the front of the crankshaft. A broken or damaged rear crankshaft oil seal or an excessively small oil return hole in the rear main bearing cap that obstructs oil return can cause oil leakage at the rear of the crankshaft. 2. Oil leakage at the front and rear oil seals: If there is oil seepage in multiple areas such as the front and rear valve covers, front and rear valve lifter chambers, oil filter, and oil pan gasket, but no obvious oil leak can be found, check the crankcase ventilation system. Clean the crankcase ventilation pipes and check if the PCV valve is malfunctioning due to carbon buildup and sticking. 3. Oil pressure: If the oil filter and some oil pipe connections still leak after tightening, check whether the oil pressure is too high and whether the oil pressure relief valve is malfunctioning.

What does the automotive TCU mean?

Automotive TCU refers to the automatic transmission control system, which utilizes computer and power electronics drive technology to achieve vehicle automatic gear shifting. It can eliminate differences in driver shifting techniques, reduce driver workload, and improve driving safety and fuel efficiency. The automotive TCU consists of a 16-bit or 32-bit processor, signal processing circuits, power drive modules, etc. Types of automotive TCUs include CVT transmissions, dual-clutch transmissions, AT transmissions, and AMT transmissions. The automotive TCU is a mechanical or hydraulic device that performs mechanical power conversion and is one of the main components of the vehicle's transmission system.

Why Won't the Mercedes Windshield Washer Spray?

Reasons why the Mercedes windshield washer won't spray are as follows: 1. If the Mercedes washer isn't spraying, first check if the pump motor is working. If not, inspect whether the fuse is blown, if the wiring connections are secure, or if the pump motor itself is burnt out. 2. Check if the water hose is cracked, if connections have come loose, or if the nozzles are clogged. Cracked hoses need replacement, loose connections should be reattached, and clogged nozzles can be cleared with thin wire. 3. If the reservoir has water and the motor is working, you can disconnect the hose below the nozzle and activate the washer switch. If water sprays from the hose, the nozzle is clogged and can be cleared with thin wire.

What does it mean to fail to smoothly shift gears up or down as instructed in Subject 3?

Failing to smoothly shift gears up or down as instructed in Subject 3 refers to not following the instructions, not operating smoothly, and not shifting gears up or down as required. Here are the relevant explanations: 1. Not following the instructions: When performing gear shifting operations, the computer will issue two commands: 'Please shift up to a certain gear' and 'Please shift down to a certain gear.' You must perform the corresponding operation based on the current gear of the vehicle and the computer's voice command. If no corresponding operation is performed after the computer issues the command, the computer will judge it as a failure. Another requirement is that the gear shifting operation must be completed within the distance range specified for the gear shifting project. Exceeding the distance will naturally be considered as not following the instructions. 2. Not operating smoothly: Starting to forcefully shift gears without fully depressing the clutch, causing gear collision. Another situation is that after shifting gears, the student is in a hurry to release the clutch, causing the vehicle to produce a noticeable jerk, i.e., feeling the front of the car suddenly nod downward. Of course, the most common unsteady operation is the mismatch between speed and gear, causing gear dragging when the speed does not reach the speed of the higher gear during the upshifting process. 3. Not shifting gears up or down as required: After the computer issues a command to shift up or down, shifting up or down incorrectly and not shifting into the specified gear as required.
