How to Open the Car Door with a Spare Key?

Generally, cars come with two keys: one remote key and one spare mechanical key, which is often hidden inside the remote key. Here’s how to use the spare key to open the car door: 1. After obtaining the spare key, you may notice there’s no visible mechanical keyhole on the exterior of the car. This is because manufacturers often hide the keyhole for aesthetic reasons. Look closely—there’s usually a decorative piece at the end of the door handle that’s roughly the size of the key. Pry it open to unlock the door. 2. At the end of the door handle, there’s a small rectangular hole. Pull the handle outward with your left hand while inserting the spare key into the hole to pry open the lock cover. Keep your left hand steady, then use your right hand to remove the lock cover. 3. After removing the lock cover, you’ll see the keyhole. Use the spare key to unlock the door. Note that the car alarm may sound when using the spare key, as the remote key’s security feature is triggered. 4. When reinstalling the lock cover, remember to pull the door handle outward first. Align the lock cover with the slot before inserting it, ensuring it’s tightly secured to prevent loss.

How to Use the Cruise Control on Roewe 550

The method to use the cruise control on Roewe 550 is as follows: 1. Press the main switch, then press the thumbwheel switch to set the cruise memory speed, and the cruise control will start working. At this time, without stepping on the accelerator pedal, the cruise control will maintain this speed. The set speed must be within the range of 35-200 km/h as specified by the cruise control system. 2. Quickly turn the thumbwheel switch upward, and the vehicle will automatically accelerate; turning it downward will reduce the speed. Each turn of the thumbwheel switch will increase or decrease the speed by approximately 1 km/h. When the desired speed is reached, release the switch immediately. 3. While the cruise control system is working, normally stepping on the accelerator pedal (such as for overtaking) can still accelerate the vehicle. When the accelerator pedal is released, the speed will return to the set cruise speed. 4. When stepping on the brake pedal or selecting a different gear, the cruise control system will be turned off. Pressing the reset switch can return to the previously set speed.

What are the effects of heavy throttle on a car?

When driving, pressing the throttle too hard can increase the impact on the vehicle's engine, thereby affecting its lifespan. The key to coordinating the throttle and clutch is to apply the throttle fully in one motion and engage the clutch contact point fully in one motion. The throttle should be applied slightly before the clutch contact point is engaged. If the coordination is done well, there should be no sound of an empty throttle or the sensation of the car jerking forward or backward. Precautions for using the throttle: 1. Operate gently and release slowly: The throttle pedal should be operated with the right heel resting on the floor of the driver's compartment as a pivot, and the sole gently pressing on the accelerator pedal. The ankle joint's extension and flexion should be used to press or release the pedal. When pressing or releasing the throttle pedal, the force should be gentle, ensuring a light press and slow release. 2. Avoid pressing the throttle pedal all the way down: When starting the engine, do not press the throttle pedal all the way down; it is better to have the throttle slightly above idle speed. When starting, it is advisable to apply the throttle slightly before the clutch engagement point, with the throttle opening at a moderate level. Releasing the clutch should be closely coordinated with pressing the throttle, and the action should be swift.

What Causes Steering Wheel Vibration When Speed Exceeds 100km/h?

Reasons for steering wheel vibration when speed exceeds 100km/h: 1. Poor tire dynamic balance. During driving, if a tire is subjected to strong local impact, it may cause the balance weights to fall off or become damaged, affecting the tire's dynamic balance. At high speeds, the driver will feel obvious vibration in the body and steering wheel, with the vibration becoming more pronounced as speed increases. 2. Significant differences in tire pressure among the four tires. When there is a large difference in tire pressure between the four tires, especially between the left and right tires, the car will experience noticeable bumps and steering wheel vibration at high speeds. 3. Poor wheel alignment. When the wheel alignment angles deviate significantly, the car may exhibit body drift and vibration during high-speed driving; it can also cause uneven tire wear, accelerating tire wear and shortening tire lifespan. Therefore, if the steering wheel vibrates during high-speed driving, first check and adjust the tire pressure, then perform a four-wheel dynamic balance, and finally conduct a wheel alignment. This should resolve the steering wheel vibration issue during high-speed driving.

What are the steps for replacing an oil filter?

The steps for replacing an oil filter are as follows: 1. Prepare tools such as a wrench, jack, oil drain pan, gloves, oil filter wrench, a new oil filter, and sufficient new engine oil. 2. Vehicle preparation. Run the engine to bring it to operating temperature. Then use the jack to lift the vehicle, engage the handbrake, and secure the front wheels with wheel chocks. Crawl under the chassis to inspect (be sure to first review any special safety precautions mentioned in the user manual). 3. Drain the old oil. Use a 15mm wrench to loosen the drain plug slightly in a counterclockwise direction. Do not loosen it too much. Place a plastic-lined pan beneath the plug (positioned slightly back to account for initial oil spray). Once the pan is in place, continue loosening the plug by hand until oil begins to drip slowly. Carefully remove the plug, avoiding contact with hot oil (it is recommended to perform maintenance when the engine is cool). 4. Remove the oil filter. Once most of the oil has drained, use the oil filter wrench to remove the filter. Open the oil cap on the engine cover and use the filter wrench to turn the oil filter counterclockwise. Unscrew the oil filter from the engine compartment, being careful not to touch the hot exhaust manifold.

What are the solutions when the brake lights don't work?

Solutions for non-functioning brake lights: 1. Check the brake light bulb. If the bulb is faulty, simply replace it. 2. Inspect the brake light switch. If the switch malfunctions, all brake lights will fail to illuminate. During troubleshooting, connect the brake light switch with a wire; if the lights turn on, it indicates switch failure, and replacing the switch will resolve the issue. 3. Examine the fuse. Some vehicles don't have a dedicated brake light fuse but share one with other electrical devices. Use a multimeter to check other electrical components in the vehicle, identify non-functional devices, and replace the corresponding fuse. 4. Inspect the brake light ground wire. The tail lights in a vehicle share a common ground wire; if this wire is broken or has a poor connection, it can also cause the brake lights to fail. 5. Check the brake light wiring harness connector. Refer to the circuit diagram to locate the connector in the brake light wiring harness, and observe if the pins inside are loose or corroded. If so, repair the affected pins or use a "jumper wire" to fix the issue. 6. Verify if the brake light wiring harness has any breaks.
