A red exclamation mark on the BMW X5 dashboard indicates a brake system malfunction, specifically the brake warning light. Brake system malfunction: The primary cause is an incomplete release of the parking brake or issues with the parking brake, triggering this warning symbol. The principle of the brake system is to generate significant friction, converting the vehicle's kinetic energy into heat. During this energy conversion process, driving with the parking brake engaged directly accelerates brake disc wear and causes the brake pads to harden due to overheating. Additionally, the parking brake cable may stretch, leading to reduced braking performance. Correct driving method: The proper driving approach is: Develop correct driving habits by always checking if the parking brake is fully released before driving. Simultaneously, pay close attention to the dashboard, as it provides the most comprehensive information. Regularly monitoring dashboard alerts and warning lights can prevent driving with the parking brake engaged.
