Model: Cloud G Lux Lava Grey (522001403)
1. Introduction
This manual provides essential information for the safe and proper use, installation, and maintenance of your Cybex Cloud G Lux Comfort Extend Infant Car Seat. Please read this manual thoroughly before using the car seat and keep it in a safe place for future reference. Adherence to these instructions is crucial for your child's safety.

The Cybex Cloud G Lux is designed for infants from 4 pounds up to 35 pounds, or up to 32 inches in height. It offers advanced safety features and ergonomic comfort for your child, both inside and outside the vehicle.
2. Safety Features
The Cybex Cloud G Lux incorporates several key safety technologies to protect your child:
- Energy-Absorbing Shell: The car seat features an energy-absorbing shell designed to distribute crash forces away from your child.
- Linear Side-Impact Protection (L.S.P.): This integrated system extends from the side of the car seat closest to the door, reducing collision forces by up to 30% in a side-impact crash.
- Anti-Rebound Base: The base is engineered to reduce forces on the child by up to 30% in both rear and front impact collisions when installed with Rigid LATCH.
- Load Leg Base: This adjustable leg extends from the base to the vehicle floor, absorbing energy and significantly reducing crash forces on the child by up to 30%.
- SensorSafe Technology: A Bluetooth-enabled chest clip provides real-time alerts to your mobile app. These alerts include notifications if the child unbuckles the chest clip, if the back seat becomes too warm or too cold, or if the driver unintentionally leaves the child behind.



3. Setup and Installation
The Cybex Cloud G Lux is designed for rear-facing installation only. Always ensure the car seat is securely installed before placing your child in it.
3.1. LATCH Installation
The car seat features a one-click rigid LATCH installation system for quick, simple, and safe setup in approximately 5 seconds. Locate the LATCH anchors in your vehicle and align the rigid LATCH connectors on the car seat base. Push firmly until you hear a click, indicating a secure connection. Always check for a tight fit by pulling on the base; it should not move more than one inch side-to-side or front-to-back.
3.2. Load Leg Adjustment
Extend the load leg from the base until it firmly touches the vehicle floor. Ensure the indicator on the load leg turns green, confirming proper contact and stability. The load leg is crucial for absorbing energy and reducing crash forces.

4.2. Adjustable Headrest and Harness
The 12-position adjustable headrest allows for proper use from birth up to 35 lbs. The harness system automatically adjusts with the headrest, ensuring a correct and secure fit as your child grows. To adjust, locate the adjustment lever at the top of the headrest, pull it, and slide the headrest up or down to the desired position.
4.3. XXL UPF50+ Sun Canopy
The extra, extra large UPF50+ sun canopy protects your child from the sun's rays. It also includes mesh air ventilation for natural airflow, keeping your child comfortable.
