It is necessary to adjust the seat belt so that it fits as closely as possible to the body without compromising the comfort of the fit. Only in this case, the seat belt will be able to effectively perform its protective function, for which it is installed on the car. A slack seat belt significantly reduces the effectiveness of the passenger's passive protection.
Keep the seat belt straps free of polish, oil, and other chemicals, especially battery electrolyte. Use neutral soap and water to clean the seat belts. The seat belt must be replaced if the belt is worn, dirty or damaged.
It is imperative to replace the seat belt assembly if it has been used by the driver or passenger in a severe vehicle collision, even if there is no visible sign of damage to the seat belt.
Do not use the seat belt if the strap is twisted.
Each seat belt must only be used by one passenger at a time. It is dangerous to fasten a passenger and a child sitting on his lap with the same seat belt.
Any changes to the design of the seat belts that interfere with the normal operation of the automatic webbing slack adjustment devices or make it difficult to adjust the belt to eliminate slack are prohibited.

It may be difficult to retract the belt onto the inertia reel if the webbing and intermediate guide bracket are dirty. Therefore, make sure that the webbing and the guide bracket are always clean (pic. 1.128).
If the seat belt is retracted, it will operate in emergency lock mode. In the emergency lock mode, the seat belt does not interfere with the comfort of the passenger. In the event of a vehicle collision, the inertia coil blocks the seat belt from being extended, which holds the passenger in place. When the seat belt is fully pulled out from the reel, it will switch to the automatic belt lock mode. If the belt feels too tight, or if it makes it difficult for the passenger to move when the vehicle is stationary or while driving, then the inertia reel has switched to automatic locking mode after the belt has been pulled too far off the reel. To return the inertia reel to a more convenient emergency lockout mode, stop the vehicle in a safe place on level ground and fully retract the belt onto the inertia reel. This will put the reel into emergency belt lock mode. Then pull the seat belt out again to the required length to buckle up.
