To fold down the rear seats in the 2018 Sagitar, first open the trunk. There are two pull rings at the opening of the trunk. Pull the rings up and then pull the rear seats down. More details about folding the seats in the 2018 Sagitar are as follows: 1. The rear seats feature a split-folding design: Two or one of the three rear seats can be folded down, meeting both passenger seating and cargo storage needs. This not only expands the trunk space but also enhances usage flexibility. 2. There are three folding ratios: one-third fold, two-thirds fold, and full rear seat fold: (1) One-third fold: Press the rear seat folding switch, hold the seat with your hand, and pull it forward to fold it down. Apply force when pressing the switch. When folding the left seat, only a single seat can be folded. (2) Two-thirds fold: When folding the right seat, two seats (middle and right) can be folded simultaneously. (3) Full rear seat fold: The rear seat backrest is a single unit.

How Much Should You Turn the Steering Wheel When Making a Right Turn?

When making a right turn, you generally need to turn the steering wheel to the 4 or 5 o'clock position, which is approximately 150 to 160 degrees. Here are some relevant details: 1. For beginners making a right turn: Avoid turning the steering wheel with just your hands; instead, move the entire steering wheel. Failing to turn sufficiently may lead you into oncoming traffic lanes. The smaller the intersection, the greater the angle you should turn the steering wheel. Turning too little may result in entering the wrong lane, so always keep both hands on the wheel. For a U-turn, turn the steering wheel with your right hand to the 10 o'clock position, using a left-hand-over-right-hand technique; for a right turn, use a right-hand-over-left-hand technique. A right turn typically requires one full rotation of the steering wheel. 2. The concept of turning the steering wheel for a right turn: A right turn usually requires one full rotation of the steering wheel. During the turn at an intersection, you may need to pause the rotation. The angle at which you turn the steering wheel with your right hand depends on the size of the intersection.

What does automotive NVH mean?

NVH stands for Noise, Vibration, and Harshness. Here is some relevant information: 1. NVH issues are ubiquitous and can be categorized into three main areas based on their sources: engine NVH, body NVH, and chassis NVH. Further subdivisions include aerodynamic NVH, air conditioning system NVH, road driving NVH, braking system NVH, etc. 2. Harshness, also known as unevenness or impact characteristics, is related to the transient nature of vibration and noise. It describes the subjective human perception of vibration and noise and cannot be directly measured by objective methods. The comfort experienced by vehicle occupants and the strength and lifespan issues of automotive components caused by vibration all fall within the scope of NVH research. From an NVH perspective, a car is a system composed of excitation sources (engine, transmission, etc.), vibration transmitters (consisting of suspension systems and connectors), and noise emitters (vehicle body). 3. NVH issues are systemic. For example, if a car's cabin noise is excessive while driving and the source is traced to the engine, this noise issue may involve three parts: the engine itself being noisy, poor vibration damping by the engine mounting components, and inadequate sound insulation technology in the cabin's front wall and floor. This illustrates how NVH problems are interrelated systemic issues.
