The smaller the rear car appears, the safer it is. When the rear car occupies 1/3 of the mirror, the distance between the two cars is 10 meters. When the rear car occupies 1/2 of the mirror, the distance is 7 meters. The following is relevant information about rearview mirrors: 1. Introduction to rearview mirrors: A rearview mirror is a tool that allows the driver to directly obtain information about the rear, side, and lower parts of the car while seated in the driver's seat. For the convenience of the driver and to prevent traffic accidents and ensure personal safety, all countries require that cars must be equipped with rearview mirrors, and all rearview mirrors must be adjustable. 2. Installation of rearview mirrors: When designing rearview mirrors, the main design considerations include the field of view (indirect vision) that the rearview mirror can obtain, image distortion, image clarity, image size, the position of the image in the rearview mirror, etc., making it easy to adjust according to changes in the driver's viewpoint. The rearview mirror should be installed at the position on the car body with the least vertical vibration.

What are the main components of an automotive power supply system?

An automotive power supply system mainly consists of a battery, alternator, and voltage regulator. The alternator is responsible for charging the battery to maintain it in a fully charged state over time, while both the battery and alternator supply power to all electrical components in the vehicle. The battery is an essential part of the automobile and can be categorized into traditional lead-acid batteries and maintenance-free batteries. Since the battery uses lead-calcium alloy for its grid framework, it produces less water decomposition during charging and has lower water evaporation rates. The alternator serves as the primary power source for the vehicle, functioning to supply electricity to all electrical devices (except the starter) when the engine is running normally (above idle speed), while simultaneously charging the battery. The voltage regulator is necessary because the alternator is driven by the vehicle's engine, and since engine speed is not constant, it would cause instability in the alternator's output voltage. Therefore, an electronic device is required to control the alternator.

How long after car glass installation can you drive?

When replacing the windshield, engineering adhesive is generally used. This adhesive becomes fully effective 24 hours after application, meaning you can drive after 24 hours. Below is additional information: 1. Laminated glass: Currently, 99% of domestic vehicle models use laminated glass for the front windshield. Laminated glass is safety glass; if subjected to external force or stone impact, it will crack but not shatter. Rear windshields and side windows mostly use tempered glass, which shatters into fine particles upon strong impact to minimize harm to occupants. Front and rear windshields are secured to the vehicle body with professional glass adhesive. 2. Precautions: To prevent wind and water leaks, avoid washing the car for three days, and remove the adhesive tape fixing the windshield position after three days. Drive smoothly, avoiding sudden braking and rapid acceleration. Try to avoid excessively bumpy roads to prevent windshield displacement.

What transmission is used in the MG HS manual version?

The manual transmission used in the MG HS is manufactured by SAIC (Shanghai Automotive Industry Corporation). SAIC Motor Corporation Limited is a leading automotive listed company in China. The MG brand originated in the UK in 1924. The MG HS 1.5T models are equipped with a 7-speed dual-clutch transmission, while the 2.0T models use a 6-speed wet dual-clutch transmission. The 6-speed wet dual-clutch transmission is produced in-house by SAIC. Dual Clutch Transmission (DCT) differs from conventional automatic transmissions - it's based on manual transmission technology while providing automatic operation. In addition to offering the flexibility of manual transmissions and the comfort of automatic transmissions, it also delivers uninterrupted power output. For daily use of the MG HS transmission, please note the following points: Do not delay transmission fluid changes for extended periods. Prolonged use of old transmission fluid can damage internal components like bearings and housings; Avoid prolonged coasting in neutral. While some experienced drivers coast in neutral with manual transmissions, doing so with automatic transmissions can cause overheating and create shocks when re-engaging D gear; Never shift into D/R gear before coming to a complete stop. Some drivers shift directly into reverse while still moving to demonstrate smooth operation, but this severely damages transmission gears and may lead to gear grinding failures over time; Avoid frequent steep hill climbs in D gear. When facing steep inclines, automatic transmissions may overheat under high load or shift prematurely causing power loss. Use manual mode to maintain lower gears or sport mode to protect the transmission; Do not tow long distances. When an automatic transmission vehicle breaks down, use a flatbed tow truck with the vehicle in N gear rather than tow ropes or direct towing.

Where is the ignition coil fuse located in the Focus?

Focus's ignition coil fuse is located in the fuse box in the engine compartment. The core components of the ignition system are the ignition coil and the switching device. Increasing the energy of the ignition coil enables the spark plug to generate sparks with sufficient energy, which is the basic requirement for the ignition system to adapt to the operation of modern engines. The Focus is a model under Changan Ford, with body dimensions of 4647mm in length, 1810mm in width, and 1468mm in height. In terms of appearance, the Focus adopts a crossover-style body kit, including a new front bumper design, black wheel arches and side skirts, and silver underbody protection. For the wheels, the base model is equipped with 17-inch five-spoke aluminum alloy wheels, while the high-end model features 18-inch five-spoke dual-tone wheels identical to the overseas version, along with LED headlights.

What lights to use on rainy days?

On rainy days, use low beam headlights, front fog lights, and clearance lights. Low beam headlights are designed for close-range illumination, with a wide coverage angle (160 degrees) but short projection distance, and their focus cannot be adjusted. Fog lights are installed at the front and rear of the vehicle. During foggy conditions with low visibility, where the driver's line of sight is limited, these lights can extend the visible distance. Especially, yellow anti-fog lights have strong light penetration, enhancing visibility for both the driver and other traffic participants. Clearance lights serve as warning lights to alert other vehicles. They are located at the front and rear edges of the vehicle. Large trucks also have clearance lights on their roofs and sides. Installed along the top edges of the vehicle, clearance lights indicate both the height and width of the car.
