Setup
LATCH Installation
The UpNGo Click features rigid LATCH connectors for secure and easy installation. These connectors click into your vehicle's lower anchors with ease and release in seconds, allowing for hassle-free transfer between vehicles.

Adjustable Headrest (if applicable for your model)
While the UpNGo Click is a backless booster, some Britax models feature adjustable headrests. Ensure the booster is positioned correctly for your child's height, allowing the vehicle's headrest to support their head and neck.
Operating Instructions
Child Positioning and Seat Belt Use
The PosturePlus contoured seat helps encourage proper posture and seat belt positioning. Ensure the vehicle's lap belt is low on your child's hips, touching the tops of their thighs, and the shoulder belt rests snugly across the center of their shoulder and chest.

Shoulder Belt Guide
Utilize the shoulder belt guide to help keep the vehicle's shoulder belt in the correct position across your child's shoulder, preventing it from riding up on their neck or falling off their shoulder.

Cup Holders
The booster includes two dishwasher-safe cup holders to keep drinks and snacks within reach. They are easy to remove for cleaning.

Maintenance
Removable SafeWash Cover
The booster seat features a removable SafeWash cover that is safe to machine wash and dry. The fabrics are naturally flame-retardant with no added FR chemicals.

Cleaning Cup Holders
The cup holders are dishwasher-safe. Remove them from the booster seat and place them in the dishwasher for thorough cleaning.
Troubleshooting
Loose Installation
If the booster seat feels loose after LATCH installation, ensure the LATCH connectors are fully engaged and pull the strap to tighten the connection. The seat should not move more than 1 inch side-to-side or front-to-back at the belt path.
Improper Seat Belt Fit
If the vehicle's seat belt does not fit properly across your child (e.g., shoulder belt on neck, lap belt on stomach), re-check your child's height and weight against the booster's requirements. Ensure the shoulder belt guide is used correctly.
