How to Use the Res and Set Buttons on the Steering Wheel?

The "Res" and "Set" buttons on the car steering wheel are mainly used for the cruise control function. "Res" stands for reset, and "Set" means setting. Below are the specific usage methods: 1. The "Res" button has two functions. The first is to restore the set speed after temporarily canceling cruise control, and the second is to accelerate to the set speed after configuring the cruise control speed. Usage of the "Res" button: When using cruise control on the highway to maintain a speed of 120 km/h, pressing the brake temporarily cancels cruise control, causing the speed to drop to 100 km/h. To return to 120 km/h, press the "Res" button, and the vehicle will automatically accelerate back to 120 km/h. Alternatively, after pre-setting the speed, pressing the "Res" button will make the vehicle accelerate to the preset speed. 2. The "Set" button also has two functions. The first is to decelerate to the set speed after configuring the cruise control speed, and the second is to set the current speed as the cruise speed. Usage of the "Set" button: When using cruise control on the highway to maintain a speed of 120 km/h, if you want to reduce the speed to 100 km/h, release the accelerator until the speed drops to 100 km/h, then press the "Set" button. The vehicle will then continue driving at 100 km/h. If initially traveling at 120 km/h, after setting the speed to 100 km/h, pressing the "Set" button will make the vehicle automatically decelerate to 100 km/h.

As a seasoned long-distance driver, I heavily rely on the RES and SET buttons on the steering wheel. The SET button is pressed after the vehicle speed stabilizes, for example, when cruising at 80 km/h on the highway—pressing it makes the system remember this speed for automatic cruise control. The RES button serves as a resume function; if you brake or cancel the cruise, pressing it again will restore the previously set speed. This feature significantly eases driving, especially on long trips where leg fatigue is common. However, it's crucial to use it only on straight and flat roads, turning it off during curves or heavy traffic—safety first. I also use it to maintain a constant speed for fuel efficiency. Frequent long-distance drivers know that achieving below 8 liters per 100 km isn't a dream. Overall, mastering these two buttons can enhance driving efficiency, but always ensure stable road conditions before adjusting speed.

Is It Safe to Buy a Mortgaged Vehicle Without Transferring Ownership?

Mortgaged vehicles without ownership transfer can be purchased, but there are certain risks involved. When a vehicle is mortgaged, it means the ownership rights temporarily do not belong to the original owner. Therefore, the owner does not have the right to transfer ownership to others. The mortgage must be fully paid off and the lien released to confirm ownership before the transfer can proceed. Below are key considerations for safely purchasing a mortgaged vehicle: 1. Source of the Mortgaged Vehicle: The origin of most mortgaged vehicles is unclear, and some may even be stolen. Purchasing such a vehicle unknowingly, while not illegal, may result in the vehicle being reclaimed or returned to its rightful owner. 2. Types of Vehicle Mortgages: Mortgaged vehicles can be categorized into fully paid and non-fully paid. Fully paid mortgaged vehicles typically have all payments completed, but the owner may be unwilling or unable to repay the financial company and does not cooperate with the transfer. In such cases, the financial company may legally transfer the debt, making these vehicles relatively safer to purchase. 3. Vehicle Condition: It is crucial to conduct a thorough inspection of the vehicle's condition before purchasing a mortgaged vehicle to identify any serious issues. It is recommended to perform this inspection with a professional. 4. GPS Tracking: After purchasing a mortgaged vehicle, a detailed inspection should be conducted to check for and promptly remove any GPS tracking devices if found.

Will the car roll away if parked in P gear without engaging the handbrake?

Parking in P gear without engaging the handbrake will not cause the car to roll away. Parking precautions are as follows: 1. Basic principle of parking: When parking, consider not only your own convenience for entering and exiting but also others', and more importantly, potential unexpected situations. 2. Waiting at signals: For waiting times exceeding one minute, it is advisable to turn off the engine to save fuel and be environmentally friendly. For waits under one minute, you may keep the engine running, shift to neutral, and engage the handbrake, but never leave the car in gear. 3. Maintain distance when pausing on the road: During traffic jams or while waiting at traffic lights, always leave enough space to maneuver out in case the car ahead breaks down, preventing you from being stuck in the middle.

What are the reasons for difficult gear shifting in Wuling Rongguang?

Reasons for difficult gear shifting in Wuling Rongguang are as follows: 1. Incorrect installation of the driven plate. 2. Difficult axial movement. 3. Warping of the driving and driven plates. 4. Loose separation lever screws. 5. Falling off of floating pins. 6. Separation lever height too low. 7. Incomplete clutch separation. Additional information on clutch issues: 1. The transmission plate of the clutch pressure plate assembly is deformed due to certain factors. The solution is to replace it with a high-quality original clutch pressure plate. 2. The transmission plate of the clutch pressure plate assembly is deformed for some reason, causing poor separation and resulting in difficult gear shifting. In this case, replace it with a high-quality pressure plate that matches the original car. 3. Due to the very large self-locking force of the clutch gear, it is particularly difficult to shift gears. Adjusting the gear stop lock and clutch cable can solve the problem. Transmission issues: 1. The components in the transmission of a new car have not reached the optimal running-in state, and some gear parts are stiff, resulting in difficult gear shifting. This situation can be resolved after a period of running-in. 2. Insufficient transmission oil. If the transmission parts lack oil or the oil quality is poor, shifting gears will feel stiff. Transmission oil is similar to engine oil and needs to be checked regularly and replenished in time. 3. Transmission failure. It may be due to a stuck transmission module or a certain friction plate, which will affect the smoothness of gear shifting. In severe cases, it may even be impossible to shift gears.

Can a Flood-Damaged Car Be Used After Replacing All the Wiring?

A flood-damaged car can still be used after replacing all the wiring. Key points for restoring a flood-damaged vehicle are as follows: 1. Exterior Cleaning: After towing the vehicle away from the flooded area, start with cleaning the exterior, including the inner sides of the front and rear bumpers, left and right side mirrors and their internal motors, and removable mirror lenses should be disassembled and cleaned. 2. Interior Cleaning: After initial cleaning, remove and clean the seats, electrical components (computers, audio systems, relays, instrument panels), door panels, headliners, interior panels, light assemblies, door waterproof liners, sunroof assemblies, etc. 3. Engine Compartment Cleaning: Remove and clean the engine hood insulation panel, disconnect the battery, open the timing belt cover to clean the interior to prevent poor crankshaft angle sensor response. Clean the generator interior with high-pressure water, and thoroughly clean the radiator and cooling fins to prevent overheating and poor cooling. Every electrical connector must be cleaned thoroughly.

Should a cracked rear bumper be repaired or replaced?

When dealing with a damaged bumper, whether to repair or replace it depends on the extent of the damage. If the internal support structure of the bumper is severely damaged or cracked, replacement is generally recommended. Below are some driving precautions: 1. Develop the habit of fastening your seatbelt: The importance of seatbelts for driving safety is self-evident, as numerous tragic incidents have demonstrated. Always buckle up when entering the vehicle. However, some people still avoid wearing seatbelts, feeling they restrict movement or cause discomfort. 2. Ensure car doors are properly closed: If you're unsure whether a door is securely closed, don't hesitate to reopen it and shut it firmly again. For vehicles equipped with door ajar warning systems, pay attention to any alert sounds or warning lights on the dashboard.
