What Causes Sudden Hardening of the Brakes?

When a car is parked for a long time, should the positive or negative terminal of the battery be disconnected?

When a car is parked for a long time, the negative terminal of the battery should be disconnected. This is because most modern cars have a negative ground system, so even if there is an operational error, it won't pose a danger. However, if the positive terminal is disconnected incorrectly, it could damage the battery or even cause a fire. When a car is parked outdoors for an extended period without being started, the battery can completely discharge in about a month, making it impossible to start the car. If the car is only parked for two or three days, it won't have a significant impact. It is recommended to start the car once a week and let it run for about 5 to 10 minutes to recharge the battery. If it's not possible to start the car once a week, the negative terminal of the battery should be disconnected to prevent discharge. When the car is ready to be used again, simply reconnect the terminal, and the car should start immediately.

Does ORA Have Airbags?

It has airbags. The function of airbags: Primarily to prevent injuries caused by collisions between occupants and interior components during a car crash, airbags usually serve as supplementary safety devices to seat belts, working in conjunction with them. Below is relevant information about airbags: How airbags work: Airbags are a passive safety system device that is only activated when the vehicle is subjected to a severe impact. Airbags determine whether to deploy based on pressure sensors in the airbag system and acceleration sensors in the restraint system ECU. Precautions: Be careful not to place objects in front of, above, or near the airbag. Since airbags can deploy in emergency situations, avoid placing items in these areas to prevent them from being projected by the airbag upon deployment, which could harm the occupants.

Why doesn't the unlock light on my Mercedes key illuminate?

It may be due to a failure in the key-vehicle sensing connection. Here are some suggestions when experiencing key-vehicle sensing failure: 1. Extract the mechanical key inside the smart key. Remove the keyless start knob cover and insert the mechanical key to start the vehicle. While the car can operate normally, the anti-theft alarm will keep sounding as the door security hasn't been deactivated. Visit an authorized dealership promptly to replace the battery or re-synchronize the smart key. 2. Check the built-in battery of the key fob - low battery power may require replacement. For emergency situations when the key battery is dead, press the key directly against the engine start button (maintaining about 1cm distance) while pressing the start button - this should allow the vehicle to start.

What does vehicle TCO mean?

TCO stands for "Total-Cost-of-Ownership", which in the logistics industry mainly refers to the total expenses from truck purchase to later usage and maintenance. Here's an introduction about TCO: 1. Expenses: Vehicle operating costs constitute the largest part of TCO. The key to reducing expenses lies in fuel efficiency. It's not recommended to take county or rural roads to save on toll fees as it's both slower and less safe. 2. Various costs involved: Variable costs that can be improved, such as fuel and maintenance; relatively fixed costs, such as vehicle purchase price, insurance, and toll fees. 3. Approaches to reduce TCO expenses: One is to optimize fuel and maintenance costs to save money, the other is to improve attendance rate to dilute relatively fixed costs.

What is the 0-100 km/h acceleration time of the Jetta?

The 0-100 km/h acceleration time of the Volkswagen New Jetta is 12.39 seconds. Below is an introduction to related information about the Jetta: Transmission: For the 1.5L model, this is a normal performance level, which is basically on par with its competitors. The Volkswagen New Jetta 1.5L uses a 6AT transmission, so it doesn't have the protection program like the DSG transmission, which imposes excessive restrictions on the engine speed during startup. Starting RPM: 2000rpm is a relatively suitable starting RPM. Due to the engine's limited power reserve, there is almost no wheel spin, and the overall momentum is very stable. Slow acceleration is a characteristic of the Jetta, mainly caused by the vehicle's heavy weight relative to its relatively small power output.

What are the measures for preventing and controlling vehicle safety risks?

Here are the measures for preventing and controlling vehicle safety risks: 1. Emotional risks: It is necessary to promptly observe the driver's emotional state before departure, inquire about their physical and family conditions from both the driver and others, and notify the dispatcher to replace the driver and vehicle if their emotional state is unstable. The driver should only be assigned tasks after resolving their emotional issues and achieving stability, ensuring they drive happily and return safely. 2. Pre-departure risks: Before departure, the driver should perform three checks and one inspection: check tire pressure, check lights and electrical systems, check steering and braking systems, and inspect engine oil, water, gauges, and the engine for normal operation. Additionally, they should verify the functionality of the onboard fire extinguisher and escape hammer. Before and after entering the garage, ensure the garage door is fully open to avoid inability to depart or damage to the vehicle and door due to improper door positioning.
