The Viano's steering is generally heavy and tends to pull slightly to the right, which is an issue with its tuning. Steering Wheel Function: The steering wheel is typically connected to the steering column via splines. Its function is to convert the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering column. Using a larger-diameter steering wheel reduces the amount of hand force required from the driver when turning. The steering intermediate shaft serves as a connecting component between the steering gear and the steering column, facilitating the standardization of steering gears, compensating for errors during manufacturing and installation, and optimizing the installation of the steering gear and steering wheel in the vehicle. Steering Wheel Fault Diagnosis: Drive at a speed of 15 kilometers per hour on a relatively open road. While driving, turn the steering wheel left and right to check if the steering is flexible and whether there is any lack of return force. Release the steering wheel to observe if the vehicle tends to drift to one side.

I've been driving the Viano for a while now, and the steering wheel does feel noticeably heavier, especially during low-speed reversing or navigating tight urban alleys, requiring some extra effort. This might be related to its body design - as a large Mercedes-Benz MPV with a tall and stable body structure, its steering system is tuned more for stability than light handling. When I've driven vehicles like the Toyota Sienna or Honda Odyssey, their steering feels much lighter. But the Viano's substantial steering feedback proves particularly useful on highways, where the vehicle feels planted and inspires confidence. After getting accustomed to it, this doesn't really feel like a significant issue, though new drivers might need some adaptation time - just applying slightly more force makes daily driving perfectly manageable. If the weight concerns you, you could visit an authorized dealership for a power steering system check to ensure everything's functioning properly.

Speaking of the Viano's heavy steering feel, it's largely related to its power steering system. As a Mercedes-Benz MPV with large dimensions and high load capacity, the steering is designed to be more robust to reduce body roll, so the heavier steering sensation during driving is normal. I frequently work with such models, and if the power steering system ages, it might feel even heavier, but overall, it's not a malfunction—just a characteristic of its handling style. Compared to compact family cars, the Viano's substantial steering gives you more confidence when turning, especially in rainy conditions or at high speeds, where the car remains stable without feeling floaty. If you suddenly notice the steering becoming excessively heavy, it's advisable to check the power steering fluid or electronic components to prevent issues like fluid leaks causing difficulty. Regular maintenance of the steering system will help keep it in good condition.

The heavy steering of the Viano is a common phenomenon, which I believe is mainly due to its positioning for commercial use, emphasizing safety and stability. After driving this model for many years, the steering wheel is indeed heavier than that of compact cars, but this actually reduces the risk of misoperation at high speeds, making the vehicle's handling rock-solid. In daily driving, you'll get used to this feel, especially during long-distance trips where the sense of direction doesn't easily waver, enhancing driving confidence. However, exerting a bit more effort during parking or at low speeds isn't a big issue, just pay attention to the power steering system to prevent wear and tear.
