istop green light indicates that the auto start-stop is in the active state, meaning the auto start-stop system can function normally at this time. Below is more information about the auto start-stop system: 1. The use of the auto start-stop system is subject to certain conditions, such as insufficient battery power, too high or too low temperature, wheels in a turning state when stopping, too steep a slope, seatbelt not fastened, etc. 2. The auto start-stop system (Start/Stop) automatically turns off the engine when the vehicle comes to a temporary stop during driving and automatically restarts the engine when it's time to move forward again.

I've been driving a car with i-stop for several years, and that little green light indicates the system is working properly. When the car comes to a complete stop, like at a red light, the engine automatically shuts off, and the green light being on means all conditions are met for a smooth restart, such as sufficient battery charge and appropriate temperature. If the light turns red or flashes, there might be an issue like a sensor or battery fault that needs checking. In daily city driving, when the green light is on, it's quite fuel-efficient, saving me around ten bucks a month on average. In winter, if it's too cold, the system might not activate and the light may change, but generally, as long as the green light stays steady, there's nothing to worry about—just drive with confidence.

Why Not Buy a Used Mazda Atenza?

Reasons for not buying a used Mazda Atenza: 1. Outdated interior design: The design of the center console area appears somewhat aged. The shape of the infotainment screen is rather conventional—while its rectangular form looks neat, the button layout and overall screen integration feel outdated, lacking a modern touch. 2. Unfashionable button design: The air vent styling and the functional buttons below them aren't particularly trendy either. Though logically positioned for convenient use, the dashboard design seems obsolete by today's standards. 3. Mediocre driving experience: Sound insulation is subpar, causing ear discomfort during prolonged highway driving. Rear passenger space is somewhat cramped, and the trunk capacity is limited. Speed bumps require early deceleration to avoid pronounced jolts.

What Causes Noise When Turning the Steering Wheel While Stationary?

The reasons for noise when turning the steering wheel while stationary are: 1. Excessive clearance in the steering rack gear; 2. Excessive clearance in the universal joint transmission device; 3. Damage to the shock absorber pressure bearing; 4. Contaminated or degraded hydraulic oil, leading to reduced lubrication performance; 5. Damage to the power steering pump. The solutions for noise when turning the steering wheel while stationary are: 1. Adjust the clearance of the steering rack gear or the universal joint transmission device; 2. Inspect and replace the shock absorber pressure bearing; 3. Replace the hydraulic oil promptly; 4. Check the working condition of the power steering pump. Steering wheels can be categorized into single-spoke, dual-spoke, triple-spoke, and four-spoke designs. Their function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft.
