Can I Change Driving Instructors During Driving Lessons?

It is possible to change driving instructors during driving lessons. However, it is generally not recommended to switch instructors during the learning process. Students who change instructors usually have to wait to be reassigned with newly enrolled students, which may delay the progress of obtaining a driver's license. Below are some important notes for the driving test: 1. During the road test, avoid coasting in neutral: Pay special attention during the road test and avoid coasting in neutral. After the vehicle comes to a complete stop, shift the gear to neutral. 2. Avoid wearing high heels during tests and practice: High heels can affect the driver's feel for the accelerator, clutch, and brake pedals to some extent, ultimately impacting practice effectiveness and test performance.

Below is the relevant introduction to fuel consumption: Factors affecting fuel consumption: The driving habits of the driver, road conditions, the weight of items placed in the car, whether the air conditioning is on, and whether the vehicle is in the break-in period, among other factors, will all affect the vehicle's fuel consumption. Methods to reduce fuel consumption: Start in a low gear, gently press the accelerator, and gradually increase speed; avoid prolonged idling or low-speed driving; avoid overloading the vehicle and a full fuel tank; avoid using high-viscosity engine oil; try to control speed with the accelerator rather than the brake.

What Are the Total Loss Compensation Standards for Flood-Damaged Vehicles?

Here is an introduction to the total loss compensation standards for flood-damaged vehicles: Level 1: Water has just reached the vehicle's chassis, and the exhaust pipe, fuel tank, and carbon canister may be submerged. The vehicle floor may become damp, but the likelihood of significant water ingress is low, and the impact on the electrical equipment inside the vehicle is minimal. Level 2: Water has submerged half of the wheels. Due to the vehicle's incomplete sealing, water will begin to enter the interior. For lower-bodied sedans, the water level inside may affect the seat adjustment motors and electrical components such as heating and ventilation. Level 3: Water has almost completely submerged the tires. At this point, the water level inside the vehicle will completely inundate the seat cushions and the central armrest area, while also affecting a large number of electrical components.

Reasons for Start-Stop System Malfunctions?

Engine start-stop system malfunctions can be caused by issues with the starting system and wiring, faults in the engine electronic control system, or problems with the anti-theft system. It is recommended to immediately contact a 4S dealership for inspection and repair. Below is an introduction to the automatic start-stop function: Automatic Start-Stop Function Introduction: The automatic start-stop system is designed to automatically shut off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and restart it when it's time to move forward again. Purpose of the Automatic Start-Stop Function: It is used during low-speed driving and frequent stops, automatically turning off the engine to avoid unnecessary fuel consumption. It also reduces the vehicle's idle time, which in turn minimizes engine carbon buildup.

Where is the Low Beam Light Switch Located?

The high/low beam light switch is typically located on the control lever on the lower left side of the steering wheel. Here are the relevant details: 1. Function: When driving on urban roads, highways while following other vehicles, or on well-lit road sections, the low beam lights can be turned on. This serves two purposes: first, it allows other drivers to see your vehicle, preventing rear-end collisions, and second, it enhances your own visibility. 2. Illumination Range: The high/low beam icons are represented by a lamp head with ray graphics—horizontal rays indicate high beams, while diagonal rays indicate low beams. Low beam lights project light downward, covering a distance of 12-18 meters in front of the vehicle with a distinct cutoff line between light and dark. Beyond this line, in an area of 30-40 meters, the illumination relies on ground-reflected light, allowing the identification of brightly colored objects within this range.
