Drip some engine oil into the keyhole and let it soak for a while, then insert the key and move it around a few times. The car keyhole has a drainage channel. If you're still concerned, you can use a hair dryer to blow it dry. Use a hair dryer to blow air at the lock for several tens of seconds. Once it's completely dry, add a small amount of engine oil into the keyhole to resolve the issue. Drip some engine oil into the keyhole and let it soak for a while, then insert the key and move it around a few times. Wrap a needle or thin wire with cotton material, insert it into the keyhole, and wipe repeatedly to absorb the water.

How to Use Turn Signals When Overtaking on the Highway?

When overtaking on the highway, turn on the left turn signal. Overtaking should be performed from the left side of the vehicle in front. After overtaking and maintaining a necessary safe distance from the overtaken vehicle, turn on the right turn signal and return to the original lane. According to Article 47 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, when overtaking, motor vehicles should turn on the left turn signal in advance, switch between high and low beams, or sound the horn. Below are relevant introductions about overtaking: 1. The vehicle in front: On roads without a central line or with only one motor vehicle lane in the same direction, when the vehicle in front receives an overtaking signal from the vehicle behind, it should reduce speed and give way to the right if conditions permit. 2. The vehicle behind: After confirming there is sufficient safe distance, overtake from the left side of the vehicle in front. After maintaining a necessary safe distance from the overtaken vehicle, turn on the right turn signal and return to the original lane.

What is the solution for oil accumulation in the throttle of the new Mondeo?

To address oil accumulation in the throttle of the new Mondeo, it is necessary to replace the throttle. Below is relevant information about the throttle: 1. Working Principle: The throttle is a controllable valve that regulates the entry of air into the engine. Once the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then ignites to perform work. 2. Location: The throttle is connected to the air filter at the top and the engine block at the bottom, often referred to as the throat of the car engine. 3. Maintenance: The throttle requires periodic replacement, with the interval primarily determined by factors such as the quality of the air filter, the quality of the engine oil, and the driving conditions of the vehicle. 4. Types: There are four types of electronic throttles: electro-hydraulic, linear solenoid, stepper motor, and DC servo motor.

What to Do When Headlights Have Water or Fog Inside?

Headlights having water or fog inside is due to condensation or water ingress in the car lights. Below are related details about headlights with water or fog: 1. Condensation in car lights: The main reason for fogging inside the lights is usually high air humidity, causing water vapor in the air to condense inside the light. Turn on the lights and wait for a while, and the fog will naturally dissipate. This kind of fogging is a normal phenomenon, related only to air humidity. Generally, the amount of condensed water vapor is minimal, and after keeping the headlights on for about 15 minutes, the moisture will evaporate without leaving any residue inside the lights. 2. Water ingress in car lights: Heavy rain, car washing, or snow can cause a significant amount of water to enter the headlights, indicating a serious sealing failure. In such cases, the headlights must be replaced or resealed. Typically, water enters from the top of the light and flows to the bottom, leaving noticeable water flow marks similar to a waterfall. Even after drying, some traces may remain. It is crucial to replace the lights promptly to prevent accidents. 3. Preventive measures: During winter and rainy seasons, it is advisable to develop a habit of regularly checking the headlights, especially after driving through water. Early detection and timely repairs can eliminate potential issues at the initial stage.

What is the correct way to use an exhaust brake?

The correct way to use an exhaust brake is as follows: 1. Automatic shutdown: When the vehicle is in motion and the driver presses the accelerator pedal or clutch pedal, the exhaust brake will automatically shut off. 2. Avoid usage: It is best not to use the exhaust brake when driving in rainy weather or on slippery roads, as it may cause the vehicle to skid or even overturn. Precautions for using the exhaust brake are as follows: 1. The exhaust brake is an auxiliary brake and cannot replace the service brake for emergency braking, nor can it be used for parking braking. However, the exhaust brake can be used simultaneously with the service brake. 2. When using the exhaust brake, the accelerator pedal should be at zero position, and the fuel injector stops injecting fuel. If the accelerator pedal or clutch pedal is pressed, the exhaust brake will automatically shut off, preventing the engine from stalling when stopping and ensuring the exhaust brake operates during fuel injection. 3. It is advisable not to use the exhaust brake on icy or slippery roads, as there is a risk of the vehicle's drive wheels skidding or sliding. 4. The braking power of the engine exhaust brake depends on the engine speed (the higher the engine speed, the better the braking effect). To ensure optimal braking performance when using the exhaust brake on long downhill slopes, select an appropriate gear (the transmission should not be in neutral) to keep the engine speed between 1600-2400 rpm.
