Where is the chassis lifting function located on the BMW 740?

1 Answers

The chassis lifting button for the BMW 7 Series is located on the central console, to the left rear of the gear shift lever. The button is marked with a small car icon featuring upward and downward arrows. To use it, start the vehicle and keep the gear in P (Park). Press and hold the lifting button, and the chassis will begin to rise. Release the button once the vehicle reaches the desired height. Principle of car chassis lifting: The car is equipped with body height sensors. The hydraulic suspension control unit collects data through these sensors (or a manual adjustment switch in the cabin) and the vehicle speed, then issues commands to raise or lower the chassis. Four electromagnetic valves inject hydraulic oil into the four shock absorbers respectively, enabling adjustable body height. The faster the vehicle speed, the lower the ground clearance of the chassis. Functions of car chassis lifting: Raising the chassis can appropriately improve the vehicle's off-road capability (including overcoming obstacles and shallow water), making it a relatively practical feature. Lowering the chassis reduces the vehicle's drag coefficient (slightly improving fuel efficiency). Additionally, lowering the chassis shortens the suspension travel, providing better lateral support and enhancing the vehicle's road performance (reducing the risk of rollover).

Can You Brake in an Emergency During a Tire Blowout?

When a tire blows out, avoid slamming on the brakes. Instead, use the gear and engine's traction to brake, while firmly gripping the steering wheel to avoid erratic steering and stabilize the vehicle to prevent loss of control. Correct handling methods during a tire blowout: 1. Keep both hands on the steering wheel at all times and avoid erratic steering; 2. Do not immediately apply full braking force after a tire blowout; 3. Release the accelerator and use the gear and engine's traction to brake, gradually reducing speed; 4. If the situation allows and is under control, take a moment (0.5 seconds) to turn on the hazard lights, then immediately resume firm grip on the steering wheel; 5. It is crucial to check the rearview mirror for other vehicles; 6. Once the speed drops below 60 km/h, gently apply the brakes to further reduce speed, using intermittent braking while continuously adjusting steering and braking to safely pull over to the roadside or emergency lane.

Can the dash cam be used when the car is not started?

Yes, the dash cam can be used when the car is not started. Here is some information about dash cams: 1. Introduction: A dash cam is a device that records images, sounds, and other relevant information during vehicle operation. 2. Purpose: After installing a dash cam, it can record the entire driving process, including video images and sound, which can provide evidence for determining traffic accident liability. For those who enjoy road trips, it can also be used to document the journey through challenging terrains. 3. Features: While driving, it continuously records video, capturing time, speed, and location, functioning much like a "black box." Additionally, dash cams can be used at home as a DV camera to record daily life or as a home surveillance device. They can also serve as parking monitors when not in use.

At what level of flooding is a car considered totaled?

For flood-damaged vehicles, there are generally three different levels. The specific descriptions are as follows: 1. Waterlogged car: If the water level exceeds the car's chassis, it is called a waterlogged car. 2. Semi-submerged car: If the water level exceeds the oil dipstick, it can be referred to as a semi-submerged car. 3. Fully submerged car: If the water level has exceeded the hood or the dashboard surface, then it is called a fully submerged car. Additional information: From a technical perspective, all three types of flood-damaged vehicles can be repaired to some extent, but even after repair, there are serious hidden dangers. The longer the soaking time, the higher the probability of faults occurring. This is similar to a watch falling into water—even if it is disassembled and dried, the watch will still malfunction and cannot be completely repaired. If the flooding is severe, the owner choosing to scrap the car is also a good option.

Can Insurance Cover Flood-Damaged Cars?

Yes, insurance can cover it. The details are as follows: 1. Only compulsory traffic insurance does not cover: If you only have compulsory traffic insurance, the insurance company will not compensate. If you have no other commercial insurance besides compulsory traffic insurance, then obviously, the loss will have to be borne by the car owner. 2. Having compulsory and commercial insurance does not cover engine damage: If you have both compulsory traffic insurance and commercial insurance, and the commercial insurance includes vehicle damage insurance, then if your car is flooded, you can call the insurance company to report the claim. The insurance company will follow the procedure to compensate. However, it is important to note that the vehicle damage insurance does not cover engine water damage. Other parts of the car, such as the interior or electronic control units, will be assessed for compensation based on the specific situation. 3. Having waterlogging insurance: If you have compulsory traffic insurance, commercial insurance, and waterlogging insurance, the insurance company will provide compensation.
