We install car seat definitely

 Fixed method of car seat includes "seat belt fixed expression" saying "ISO-FIX (Aiso fix) is rigid". We read manual carefully, and let's establish all definitely.
 Conventionally, most were seat belt fixed expressions, and a lot of use by wrong installation might not show original security performance. Therefore ISO-FIX fixation-style type which fixed seat and car seat on the car side came to be marketed by common attachment.

Precaution

Car seat which adapted to your car

 All car seats are not attached to all cars. We confirm whether we are attached in reference to "car seat conformity table according to car model" given by manufacturers, and let's choose adapted car seat as your car.

As far as setting of car seat is possible; in rear seat

 When air bag is generally equipped passenger seat with and operates, shock is very greatly dangerous. When we attach car seat to passenger seat, we slide seat behind as possible, and let's reduce shock from air bag out of necessity.
※ As previously described, you must not attach newborn baby, (baby sheet) that it is for baby/infant which you must install backward to passenger seat.

Without forgetting adjustment of shoulder belt

 Please go without forgetting adjustment of shoulder belt if we let we install car seat, and child sit down. When shoulder belt loosens, child steals out of car seat and is in danger of shoulder belt hanging over neck, and having injury. 
 In addition, we may unclothe when we wear thick coats so that body adheres to car seat.

We are careful about burns

 The car seat body, buckle, metal fittings part of belt may become hot at the time of parking under hot weather. When we let child sit down, we touch all parts, and let's confirm.
