To open and replace the battery in an MG car key, follow these steps: 1. Locate the silver button at the top of the car key; 2. Press the button, and the mechanical key will automatically pop out; 3. Once the key is open, you will see a gap in the middle. Use a flathead screwdriver to slide along the gap and pry it open; 4. After opening the back cover, you will see the battery panel. Remove the old battery and install the new one. Taking the 2019 MG EZS as an example, its body dimensions are: length 4314mm, width 1809mm, height 1620mm, with a wheelbase of 2585mm and a curb weight of 1518kg.

How to Reinstall a Fallen ETC Device?

ETC device installation procedure is as follows: Upon receiving the device, first check if the ETC card and On-Board Unit (OBU) are damaged. Press the anti-tamper button on the back of the OBU. A red light will briefly illuminate, and the OLED screen will display 'Label Invalid' or 'Please Insert Card', indicating the device is functioning normally. Clean the front windshield, ensuring the glass surface is smooth, clean, and dry. Then peel off the adhesive backing film of the OBU and attach it to the installation position. Press firmly for 2-3 minutes to eliminate air bubbles. Insert the ETC card with its front facing the driver and the back facing the windshield, ensuring the chip is properly inserted into the OBU device. ETC installation positions: For small vehicles like cars and minivans, the ETC card and OBU should be installed on the upper middle part of the front windshield. For large vehicles such as trucks and buses, the installation position is on the lower middle part. ETC installation requirements: The height should be no less than 1.2 meters and no more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the OBU surface and the horizontal plane).

What does resaccel mean on a car?

Resaccel on a car is a control indicator for cruise speed. The cruise control system, abbreviated as CCS, is also known as the cruise control driving device, speed control system, or autonomous driving system. With this device, when driving on highways for long periods, the driver no longer needs to control the accelerator pedal, reducing fatigue and unnecessary speed changes, which can save fuel. However, cruise control should not be used in the following situations: 1. Non-enclosed road sections. The road conditions in such areas are very complex, with numerous intersections and roads leading in all directions. Using cruise control may prevent timely speed adjustments based on actual road conditions, increasing the risk of accidents. 2. Rainy or snowy weather. Due to slippery road surfaces in such conditions, the car's handling is reduced, so cruise control should not be used for safety reasons. 3. Mountainous roads or roads with many turns. These conditions generally require reduced or low-speed driving. Using cruise control, which maintains a constant speed, is not conducive to safe driving and should be avoided.

How to Eliminate Odors in Used Cars?

There are several specific methods to eliminate odors inside used cars: 1. Maintain long-term ventilation in the car and change bad habits like smoking or eating inside. The odors left from smoking or eating strongly flavored foods in the car are the hardest to eliminate. Over time, they cling to the interior and are difficult to dissipate on their own. Developing good habits and ensuring long-term ventilation can keep the air inside the car flowing, preventing odors from forming and helping to remove them. 2. Place activated charcoal bags or scented sachets in the car. Activated charcoal bags or scented sachets can absorb odors and even harmful gases from the air inside the car, making them suitable for eliminating long-term odors. They are also inexpensive and easy to use, requiring only periodic replacement by the owner. 3. Place fruit peels in the car. The peels of fruits like pomelo, orange, and lemon carry natural fragrances that can improve air quality to some extent. Placing them near the air conditioning vents maximizes their effectiveness. Since peels can rot easily, remember to clean or replace them after some time. 4. Use a car air purifier. The primary function of a car air purifier is to filter harmful substances from the air, improving air quality inside the car. It can effectively purify odors, harmful gases, bacteria, and viruses, providing the owner with a better in-car air environment. 5. Regularly clean the air conditioning system. Many people never clean their car's air conditioning system for years, leading to the accumulation of bacteria and dirt on the air filter, which causes odors. Regular cleaning of the air conditioning system and replacing the air filter can help prevent odors and ensure the efficient performance of the air conditioning system.

Is There a Charge for Repairs During the Car Warranty Period?

Not necessarily. During the car warranty period, as long as the malfunction or part damage occurs under normal usage conditions as specified, the manufacturer will provide free repair or replacement of corresponding parts for the owner. However, this does not mean that the car can be 'repaired as desired' just because it is within the warranty period, nor can it be simply understood as 'everything is covered.' More details are as follows: 1. The commonly mentioned 5-year or 100,000-kilometer warranty mainly covers the car's core components, such as the engine, transmission, drivetrain, and chassis. The likelihood of these components failing is relatively low, and the repair costs are high. It is rare for these core components to develop issues within the 5-year period. 2. For wear-and-tear parts like tires, rims, headlights, and brakes, car dealers typically offer only a 3-6 month or 5,000-kilometer warranty. 3. The car warranty period refers to the timeframe during which the car manufacturer promises to provide free repairs and maintenance for any faults arising from quality issues when selling the product to consumers.

Which is Safer: Automatic or Manual Transmission Cars?

Based on historical traffic accident data, manual transmission vehicles are considered safer. When emergency braking is required, in a manual transmission car, pressing the brake pedal fully will cause the engine to automatically shut off after the vehicle comes to a complete stop, thereby cutting off power. In contrast, automatic transmission vehicles do not shut off the engine when the brake pedal is fully pressed after stopping, maintaining power output and resulting in longer braking distances, which poses safety risks. The differences between automatic and manual transmission cars include the following: 1. Price difference. For the same model and configuration, automatic transmission variants are more expensive than manual ones. 2. Different transmissions. Automatic cars use automatic transmissions, while manual cars use manual transmissions. 3. Driving methods vary. Driving an automatic car only requires selecting the desired gear (e.g., shifting to drive mode without further gear changes, as the transmission shifts automatically). Manual cars require drivers to manually shift gears according to speed and RPM to select the appropriate gear.

At how many kilometers should a major maintenance be performed?

Generally, vehicles require a major maintenance service when they reach 30,000 kilometers. This includes replacing components such as engine oil, oil filter, air filter, fuel filter, power steering fluid, and spark plugs. Below are the specific details of the maintenance: 1. Lubrication System: The vehicle should be cleaned and maintained every 5,000km to 10,000km. 2. Fuel System: The vehicle should be cleaned and maintained every 10,000km to 15,000km, or when symptoms such as engine stuttering, sluggish acceleration, black smoke emission, lack of power, or increased fuel consumption are observed. 3. Cooling System: The vehicle should be cleaned and maintained once during the transition between winter and summer seasons. Under normal driving conditions, it should be cleaned and maintained every 6 to 8 months, or when issues such as overheating, coolant leakage, or boiling occur. 4. Transmission: The vehicle should be cleaned and maintained every 20,000km to 25,000km, or when symptoms such as transmission slippage, high engine temperature, delayed gear shifting, or system leakage are encountered.
