Seat adjustment in subject 2 exam.

The front and rear can be adjusted under the seat, and the height can be adjusted on the left side of the seat. It is generally necessary to adjust the arm to the steering wheel, and some people are used to leaning forward according to their height.

If the adjustment is very standardized, it can be done as follows:

Adjust up and down

Adjust the seat up and down so that the head is at least one fist away from the roof. If the seat is adjusted too high, the head will easily hit the roof when the car bumps, which will affect driving.

Front-back adjustment

When the foot presses the brake pedal to the deepest point, the legs should still be bent to a certain extent, and then the front and rear position of the seat is more suitable.

Lumbar support adjustment

Let the seat support your waist. When you lean back, don't let your waist droop, which can reduce fatigue during driving. Of course, some seats don't have the function of lumbar support, so you can buy a small cushion and support it behind your waist.

Headrest adjustment

The best position of the headrest is that the center line of the headrest is just in line with the eyebrows.

Seat belt adjustment The seat belt should be placed at the shoulder blade position, not too close to the neck. When a man drives, remember to put his tie outside his seat belt.

Use of steering wheel

The back is close to the seat, and when the arm is stretched out on the steering wheel, the wrist just falls on the steering wheel, which is the best distance of the steering wheel. Through the spokes of the steering wheel, you can just see the mileage, speed and fuel consumption of the dashboard, and the edge of the steering wheel will not hinder the line of sight, which is the best position.

When turning the steering wheel, if the steering wheel is regarded as the surface of a clock, then the initial position of the hand is at three o'clock and nine o'clock. The thumb naturally rests on the steering wheel spokes. Some people like to hold the steering wheel with their thumbs inward, thinking that this can better control the steering wheel. In fact, this is a bad habit. On the one hand, the steering wheel is not flexible, on the other hand, it is easy to damage the thumb when getting off the car in bad road conditions. It is not a good driving habit to turn the steering wheel a little, which will make the driver not know how far the steering wheel has turned and it is not easy to grasp the steering angle of the car body.

Mirror adjustment

For the exterior rearview mirror, the horizontal line where the sky meets the ground is just one-third above the exterior rearview mirror, that is, two-thirds of the ground and one-third of the sky can be seen in the exterior rearview mirror, which is the best position for up-and-down adjustment. When adjusting left and right, let the car body also appear in the line of sight of the exterior rearview mirror, but not too much, as long as you can grasp the situation near the car body.

For the interior rearview mirror, when there is a car behind, it is best to let the whole car appear in the interior rearview mirror. Of course, if you can't take care of everything, the principle is that you can't get on and off the bus. The most important thing is to master the ground situation. Of course, it is best to replace the inner rearview mirror with a convex mirror, so that the field of vision is very broad. With the help of this convex mirror, we can clearly grasp the situation at the rear of the vehicle. Another thing to remind is not to place large items near the rear window of the vehicle, so as not to affect the rear view effect of the interior rearview mirror.
