To keep your child safe the car seat must be properly installed in your car. If it is not properly installed it could come loose or move and your child could be injured in a crash.
You can install a car seat yourself.
The car seat should come with instructions (manufacturer's instructions) on how to install it. You should follow the instructions step by step. Most car seats need to be connected to an anchor point to hold them tightly in place.
If you can't find an anchor point check your vehicle's owners manual. If you don't have an anchor point you must get one made and fitted by a professional. If you want help to install a car seat RACT or an accredited car seat fitter can help.
ISOFIX is a way to attach a car seat. This technology is fairly new to Australia. ISOFIX car seats have two arms on the back that fit into clips built into on the bottom of the back seat.
ISOFIX MUST be used together with a top-tether strap connected to an anchor point to hold them tightly in place. Some new cars have ISOFIX anchor points, check your vehicle manual to find out where they are.
It is illegal to use an ISOFIX car seat that does not meet the Australian Standards. This means it will have the AS/NZS 1754 code on the label.
