Why is it important to know the vehicle's center of gravity?

Knowing a vehicle's center of gravity is crucial for determining safe lifting points during maintenance or tire service. The center of gravity is the point where the vehicle's weight is evenly distributed in all directions. When lifting a vehicle, especially when using jacks or hoists, understanding this point helps ensure stability. If a vehicle is lifted incorrectly or from the wrong point, it could tip over, posing safety risks to the technician and causing potential damage to the vehicle.

The other options do not directly relate to the significance of the center of gravity. Driving speed is influenced by many factors, including engine power and aerodynamics, but not specifically by the center of gravity. Tire pressure needs are typically determined by manufacturer recommendations based on load and driving conditions, rather than the center of gravity itself. The location of the battery is generally unrelated as well and is more about the vehicle's design than its center of gravity.
