Learn how to install your Silver Cross Approach Plus 360 car seat with the Base Plus 360, including ISOFIX setup, rotation checks, and common mistakes to avoid.

Quick answer

Install the Approach Plus 360 by securing the Base Plus 360 with ISOFIX and the support leg, then click the seat onto the base and verify a secure fit. Always check the base indicators and seat rotation before placing your child in the seat.

Why proper installation matters

A correctly installed car seat is the single most important factor in keeping your child safe on the road. The Approach Plus 360 is a multi-stage seat designed to grow with your child from birth up to 19.5kg (approx. 4 years old), so getting the installation right from the start ensures that every journey is as safe and comfortable as possible.

Understanding the Base Plus 360

The Base Plus 360 is the rotating base that pairs with the Approach Plus 360. It features a 360° spin, which makes it easier to place your child in the seat and buckle up without straining your back. The base also includes a support leg and ISOFIX connectors, which together provide a sturdy and secure fit in your vehicle.

What to check before you start

Before installation, ensure your vehicle has ISOFIX anchor points and that the seat is compatible with your car. Also, check that the base and seat are clean and free from any damage. If your vehicle does not have ISOFIX, this seat may not be suitable—always refer to your vehicle's manual and the car seat instructions.

Step-by-step installation

Prepare the base: Place the Base Plus 360 on the vehicle seat, ensuring the ISOFIX connectors are aligned with the anchor points. Extend the support leg so it touches the floor firmly. Check that the support leg is fully extended and locked; a loose leg can reduce stability.
Secure the ISOFIX connectors: Push the base back until both ISOFIX connectors click into the vehicle's anchor points. Look for the green indicators on the base to confirm a secure connection. If you see red, the connection is not secure—try again and ensure the seat belt is not in the way.
Adjust the support leg: Press the support leg release button and slide the leg down until it touches the floor. Ensure the leg is perpendicular to the floor and the indicator shows green. The support leg must not be suspended in the air; it should bear weight to reduce forward movement in a crash.
Attach the car seat: Hold the Approach Plus 360 by the handle and align the seat's connectors with the base. Push down firmly until you hear a click, indicating the seat is locked onto the base. Try to lift the seat from the base—if it moves, it is not locked correctly.
Verify the rotation: Rotate the seat 360° to ensure it spins smoothly and locks in both forward-facing and rear-facing positions. Check that the rotation release button is working properly. If the seat does not rotate smoothly, re-check the base installation and the seat attachment.
Check the harness and recline: Adjust the harness height and recline position according to your child's size and age. Ensure the harness is snug and the chest clip is at armpit level. A loose harness can be dangerous; always do the pinch test to ensure it is tight.
