What Does Suspension Stiffness Adjustment Mean?

Suspension stiffness adjustment refers to the regulation of a vehicle's suspension comfort level, which typically includes three modes: Normal, Sport, and Comfort. These modes cater to different needs of the driver at various levels. The driver can easily switch between modes by operating a switch to adapt to different road conditions, making the operation relatively convenient. The adjustment of suspension stiffness is achieved by the control unit regulating the adjustment valve on the shock absorber, thereby controlling the internal hydraulic circulation of the shock absorber to change its damping coefficient. The primary purpose is to ensure a balance and switch between the vehicle's handling and comfort. It is important to note that the stiffness adjustment of the chassis suspension is distinctly different from the height adjustment of the chassis suspension. Height adjustment, commonly found in air suspensions, is designed to improve the vehicle's off-road capability by increasing ground clearance or to enhance handling by lowering the center of gravity, with these two aspects being mutually exclusive.

As a veteran driver with nearly two decades of experience, I rely heavily on suspension stiffness adjustment in my daily driving. Simply put, it allows the suspension system to be tuned softer or firmer to adapt to different driving scenarios—for instance, setting it softer when driving in the city reduces excessive jolting, making the ride more comfortable; while firming it up on highways or during turns keeps the car planted like it's rooted to the ground, significantly boosting safety. This is typically electronically controlled, with some vehicles featuring air suspension that automatically senses road conditions and adjusts spring damping, making it effortless and worry-free. I often soften the suspension when taking family outings—less sway in the back seats means the kids sleep more soundly; on rainy days with slippery roads, I stiffen it to enhance grip and prevent skidding. This feature is common in many SUVs and premium sedans, and personally, I consider it a great ally in elevating driving comfort.

I'm passionate about studying cars. Simply put, suspension stiffness adjustment means the suspension can be tuned to be softer or firmer, adapting to various road conditions and preferences. When driving on highways, I prefer switching to sport mode where the suspension firms up, providing quicker turn-in response and an incredibly strong sense of control. In urban areas, I set it to comfort mode for better shock absorption, eliminating that annoying bumpy ride. This technology is achieved through electronic systems or air springs – for instance, automatically softening to absorb impacts during off-roading, or stiffening when fully loaded to maintain stability. I've discussed this at car club meetups, and proper tuning can even save some fuel by reducing unnecessary body vibrations. Many new cars now come with this feature as standard equipment – it's user-friendly with simple manual switching. Compared to conventional suspensions, this adjustability makes long-distance driving more enjoyable, effortlessly adapting to gear shifts and changing road conditions.

Where is the air filter of the Qashqai located?

The air filter of the Qashqai is located behind the glove box on the passenger side. Additional information: Function of the air filter: The air filter serves a filtration purpose, cleaning the air entering the cabin from outside, thereby improving air purity. The typical filtration targets include impurities in the air, such as tiny particles, pollen, bacteria, industrial exhaust, and dust. The air filter prevents these substances from entering the air conditioning system, protecting the system from damage, providing a good air environment for passengers, safeguarding their health, and preventing window fogging. Cleaning tips: If the filter is dirty, clean it by blowing compressed air from the opposite side. Hold the air gun about 5 cm away from the filter and blow at a pressure of 500 kPa for approximately 2 minutes. The air filter tends to accumulate a lot of dust, and blowing compressed air can remove the loose dust.
