The reason for the jerk when releasing the brake to start an automatic transmission car is the presence of stubborn dirt and impurities inside. Especially when dirt and impurities accumulate inside the valve body, forming blockages that prevent effective regulation of oil pressure, leading to jerking, impact, and slipping issues. Here are some precautions when starting: Gear lever position: Shift gears after pressing the brake pedal and check if the gear lever position is correct. Preventing severe vehicle shaking: When starting over bumps or steps, it's best to press the brake pedal with your right foot, slightly release the right foot while the car is stationary, and gently press the accelerator pedal. The moment you pass the step, immediately lift your right foot and lightly press the brake pedal to prevent severe vehicle shaking. Engine speed: Do not let the engine speed be too high when starting; wait for the engine speed to drop before starting.

What are the pros and cons of automatic transmission ECO mode?

Pros and cons of automatic transmission ECO mode: The biggest advantage of enabling ECO mode in a car is improved fuel efficiency, which reduces operating costs. The downside is that the vehicle may experience slightly reduced power output. Additionally, if the engine frequently operates at low speeds, fuel combustion may become insufficient, leading to increased carbon deposits in the engine. ECO stands for the initials of three English words: Ecology, Conservation, and Optimization. It is a vehicle energy-saving mode that achieves fuel efficiency when activated. Working principle of ECO: ECO primarily makes comprehensive judgments and analyses of various factors affecting fuel consumption during vehicle movement, including automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal fuel quantity to supply the engine, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls engine RPM through appropriate gear selection to minimize unnecessary fuel consumption.

Will a Car Get Damaged If Submerged in Water?

Car submerged in water may not necessarily get damaged. Hazards of water immersion: 1. Corrosion of chassis: If the water isn't deep, just passing the chassis into the cabin, it can cause corrosive damage to the fixing bolts at the bottom of the vehicle compartment used for connecting external attachments, weakening their tensile fastening ability, and in severe cases, causing detachment. 2. Compromising body tightness: Sealing rubber strips and damping rubber rings attacked by silt will oxidize and harden, accelerating wear. While stationary it's manageable, but when driving, unusual noises or wind noise are inevitable. 3. Odor and mildew: Water entering the car will turn into acidic mixed liquid, absorbed by the interior fabrics, inevitably producing odors when heated and mildewed. If not cleaned, it can also attack adjacent metal parts, causing rust and weakening the metal's hardness.

Who Decides Where to Repair the Car When the Other Party is Fully at Fault?

When the other party is fully at fault, the location for car repairs can be determined through mutual negotiation. If no agreement is reached, you can choose the repair location yourself. When issuing the invoice, request the other party to pay. If the other party refuses to cover the repair costs, you can pay upfront and then retain the repair cost receipts to file a lawsuit in court, demanding compensation from both the insurance company and the other party. Two solutions if the other party, being fully at fault, does not compensate: 1. Subrogation: Applying for subrogation (right of recovery) from your own insurance company is the most hassle-free method. This involves having your insurance company compensate you first, then transferring the right to recover from the at-fault party to the insurance company. The insurance company will then seek compensation from the at-fault party. 2. Legal Action: Apart from subrogation, you can also file a lawsuit in the local court to protect your legal rights. However, this method is more cumbersome, time-consuming, and labor-intensive, and is not recommended.
