What Causes Car Shaking While Driving?

Driving a car with shaking issues can be attributed to the following reasons: 1. Aging engine components: Car shaking is often related to the aging of engine mounts (also known as engine cushions). Engine mounts act as the shock absorption system for the engine, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations can transfer to the steering wheel and the cabin, causing shaking during idle. 2. Ignition system problems: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can also lead to such issues.

What are the precautions when picking up a Mercedes-Benz?

When picking up the car, it is essential to thoroughly inspect the vehicle and ensure all accompanying items are complete. More details about picking up the car are as follows: 1. The accompanying items of the car include the instruction manual, user manual, maintenance manual, spare tire, jack, tire-changing tools, and first aid kit. 2. Some high-end Mercedes-Benz models are equipped with run-flat tires, so these Mercedes-Benz vehicles do not have a spare tire, nor do they include tire-changing tools or a jack. 3. When picking up the car, a thorough inspection is necessary. During the inspection, first check the exterior paint for any flaws, then examine the main screws in the engine compartment for signs of tampering or rust. Inspect the interior for any defects, and finally start the engine for a test drive. If everything is in order, you can proceed to the vehicle management office for registration. 4. Many parts in the engine compartment have production dates, such as the headlights, radiator, and radiator frame. Many other components on the car also have production dates, such as the glass and tires. The production dates of all parts on the car should be earlier than the vehicle's production date; otherwise, they have been replaced later. The vehicle's production date is indicated on the nameplate on the B-pillar and also on the nameplate in the engine compartment. During the inspection, you can check the production dates of various components on the car and compare them with the vehicle's production date to determine if any parts have been replaced later.

What are the steps for remote one-button start on the new LaCrosse?

The steps for remote one-button start on the new LaCrosse: First, directly press the lock button on the remote key fob, then immediately press and hold the remote engine start button to start the vehicle. The LaCrosse's remote start function uses the remote key fob to remotely start the engine and activate the car. Remote car starting is quite common, with most mid-range and high-end vehicles equipped with this feature. Below are the characteristics of remote car starting: 1. High reliability: Since remote car starting is structurally identical to manual ignition in the vehicle's setup—both initiate the engine via an electric motor—there is no mechanical wear on the heater, thereby reducing failure rates. 2. Convenience: Although remote car starting cannot be scheduled like parking heaters, the remote start method is still very convenient. The remote range is typically no less than 50 meters, allowing the engine to be started in advance from home or work if the car is parked in a ground-level parking lot. 3. Automatic timing: Usually, if no operation is performed after a certain period following a remote start, the engine will automatically shut off to prevent potential fuel waste from forgetting to turn it off.

Is the License Plate Reversed in the Rearview Mirror?

Due to the front-to-back installation of the rearview mirror, its imaging is reversed front-to-back compared to a regular mirror. Here is some information about rearview mirrors: 1. The car rearview mirror reflects the situation behind, beside, and below the car, allowing the driver to indirectly see these areas clearly. It acts as a "second pair of eyes," expanding the driver's field of vision. 2. During driving, road traffic conditions are constantly changing dynamically. When observing and collecting traffic information, drivers sometimes only notice the traffic situation ahead and overlook the conditions on the sides and behind. In other words, failing to properly use the rearview mirror for observation can lead to incorrect judgments and wrong operational measures. In mild cases, this affects the normal driving of the vehicle; in severe cases, it can result in traffic accidents.
