What does the R warning light indicate?

[VonDavid]

r is the tire pressure missing alarm light fault. When this light illuminates, it indicates that the tire pressure of one of the car's tires is insufficient and requires inflation. Tire pressure is akin to the blood pressure of a car; its level plays a crucial role in the vehicle's performance and power. Both excessively high and low tire pressures are harmful to the car. The operational steps are: 1. Step on the car's brake pedal to prepare for engine start; 2. Press the start button. The hazards of excessively high tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Causing steering wheel vibration and deviation, lowering driving comfort; 3. Accelerating wear on the central tread pattern of the tire, reducing tire lifespan; 4. Increased body vibration, indirectly affecting the lifespan of other components.
