RES on a car stands for the resume function of the cruise control system, which restores the set speed. The following are relevant introductions about RES: 1. RES has two functions: On a car, RES is the cruise control system's function to resume the set speed. RES has two functions: one is for acceleration after setting the cruise control, and the other is to press RES to restore the previously set speed after temporarily canceling the cruise control. 2. Driver's usage: The driver selects the speed according to road conditions and activates the cruise control system by pressing the switch to replace throttle pedal control. Based on the impact of slopes and road conditions on the speed, the system automatically adjusts the fuel supply, allowing the vehicle to maintain a constant speed. 3. The role of RES: With this device, after driving for a long time on highways, the driver no longer needs to control the throttle pedal, reducing fatigue and unnecessary speed changes, which can save fuel.

Introduction: The maintenance light is a reminder function set by the manufacturer to alert the vehicle owner to perform maintenance at certain mileage or time intervals. It appears in the form of a dashboard or screen message or indicator light. Resetting the maintenance light means clearing the reminder information after maintenance is completed, which is essentially an information reset. 2. Function: The purpose of the maintenance light is to record the mileage of important components, much like a timer in a sprint race. It serves as a reminder for both the vehicle owner and automotive repair personnel. If the owner replaces related components but does not reset the light, it will not affect the vehicle's performance. However, it may cause inconvenience for the next replacement, as it will be difficult to accurately track the usage time of the new components.

What Causes a Motorcycle to Lose Power and Stall When Accelerating Uphill?

The reasons why a motorcycle loses power and stalls when accelerating uphill are: 1. Clogged main jet: During the idle period just after starting, the carburetor can only deliver combustible mixture to the cylinder head through the idle jet to maintain stable idling, which is caused by the main jet being blocked by the needle valve. 2. Insufficient mixture: When the throttle is opened wider, the intake air volume increases instantly, making the mixture in the cylinder head too lean, which prevents the engine's combustible mixture from burning continuously in a short time. Additional information: 1. Throttle: Also known as the "air valve" or "throttle valve," it is the control device that regulates the engine's power (thrust). 2. Function: In piston-type aircraft engines, the throttle controls the opening of the carburetor's throttle valve to regulate the cylinder's filling volume, thereby determining the engine's output power; in gas turbine engines, the throttle controls the metered fuel flow of the fuel regulator, thereby determining the thrust produced by the engine.

How many kilometers does an Audi A6 need for maintenance?

Audi A6 new cars require an oil change if the driving time has not reached 12 months but the mileage has reached 15,000 kilometers. If the annual mileage exceeds 30,000 kilometers, maintenance must be carried out according to the 30,000-kilometer regular maintenance specifications, not the 12-month regular maintenance specifications. Brake fluid should be replaced every 24 months. Car maintenance is a preventive measure that involves regular inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain parts of the car, also known as car servicing. Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. Features of Audi: Its characteristics are more luxurious, more dynamic, and more mature.

How Many Kilometers for the Break-in Period?

The break-in mileage for a new car is 1000 kilometers to 3000 kilometers. Here are some precautions during the break-in period: 1. Warm up before starting: This applies to fuel-injected cars. Before starting, turn the key to the second position and wait for 5-10 seconds, then start the engine. This is because the fuel pump begins working as soon as the ignition is turned on, adjusting oil pressure and fuel injection volume. Therefore, waiting a few seconds before starting helps protect the new car's engine. 2. Avoid emergency braking: Emergency braking not only shocks the braking system during the break-in period but also increases the impact load on the chassis and engine. It is best to avoid emergency braking within the first 300 kilometers of driving. 3. Avoid overloading: If a new car is driven at full load during the break-in period, it can cause damage to the mechanical components. Therefore, within the first 1000 kilometers of driving, domestic cars should not exceed 75%-80% of the rated load, and imported cars should not exceed 90% of the rated load.
