Quick Answer
To install the Clek Car Seat Adapter for UPPAbaby, first confirm your stroller model and adapter compatibility.

If you own a Clek infant car seat and an UPPAbaby Cruz or Vista stroller, the Clek Car Seat Adapter is the key to a seamless travel system. This adapter lets you click your Clek Liing or Liingo seat directly onto your stroller, so you can move from car to stroller without waking your baby.

In this guide, we'll walk you through the installation process step by step, covering compatibility, mounting, and safety checks. Whether you're a first-time parent or just need a refresher, you'll have your adapter installed in minutes.
Compatibility Check
Before you start, verify that your stroller and car seat are compatible with the Clek Car Seat Adapter. The adapter is designed for UPPAbaby Vista (including Vista V2 and V3) and Cruz strollers manufactured from 2015 to present. It is not compatible with older Vista models or other stroller brands.
Your Clek infant seat must be a Liing or Liingo model, as these are the seats the adapter is specifically engineered for. Check the base of your seat for the model name to confirm compatibility.
- Compatible strollers: UPPAbaby Vista (2015+), Vista V2, Vista V3, Cruz (including Cruz V3).
- Compatible car seats: Clek Liing and Liingo.
- Not compatible with UPPAbaby Minu or other non-listed strollers.
Prepare the Stroller and Adapter
Start by ensuring your stroller is in the fully assembled and unfolded position. Remove any existing adapters or accessories from the stroller's mounting points. If you have a bassinet or toddler seat attached, detach it to access the adapter connectors.
Take the Clek Car Seat Adapter and inspect it for any damage or wear. The adapter should have two arms that will attach to the stroller's sides. Familiarize yourself with the attachment points: they are typically located on the inside of the stroller frame, near where the seat attaches.
- Have the adapter and stroller on a flat surface for stability.
- Make sure the stroller is locked in the open position to prevent folding during installation.
Attach the Adapter to the Stroller
Align the adapter arms with the mounting points on the stroller. On UPPAbaby Vista and Cruz, these are usually small notches or brackets on the frame. Push the adapter firmly onto the mounting points until you hear a click or feel it lock into place.
Repeat on the other side. Ensure both sides are securely attached and the adapter is level. Give it a gentle tug to confirm it doesn't come loose. If it moves, realign and push again until it clicks securely.
- The adapter should sit flush against the stroller frame.
- If the adapter doesn't click, check that you're using the correct mounting points and that the adapter is right-side up.
Connect Your Clek Infant Car Seat
With the adapter in place, it's time to attach your Clek Liing or Liingo car seat. Hold the car seat horizontally and align the connectors on the sides of the seat with the adapter's latches. Lower the seat onto the adapter until you hear a distinct click on both sides.
After clicking, pull up gently on the car seat to ensure it's locked. The seat should not lift off the adapter. If it does, re-seat it and try again. Some parents find it easier to attach the seat while the stroller is stationary and the brake is engaged.
- Always check for a firm click on both sides.
- If the seat doesn't click, check that the adapter is properly installed and the seat is aligned correctly.
Safety Check and Usage Tips
Before using the travel system, perform a final safety check. Tug the car seat from different angles to ensure it's firmly attached. Check that the adapter is still securely mounted to the stroller. The car seat should not move more than an inch in any direction.
When using the stroller, always follow the stroller manufacturer's weight limits for the adapter and car seat combination. Remember that the adapter is designed for the Clek Liing and Liingo seats only; do not use it with other car seat brands. Also, ensure your child is secured in the car seat according to the car seat manual.
- Never use the adapter with a car seat that is not listed as compatible.
- Periodically check the adapter and connections for wear and tear.
Installation Steps
- Step 1: Confirm Compatibility: Check that your stroller is an UPPAbaby Vista (2015+), Vista V2, V3, Cruz, or Cruz V3, and that your car seat is a Clek Liing or Liingo. Using incompatible products can lead to unsafe installation.
- Step 2: Prepare the Stroller: Unfold the stroller, engage the brake, and remove any existing adapters or seats from the mounting points. Ensure the stroller is stable and the mounting points are clear.
- Step 3: Attach the Adapter: Align the adapter arms with the stroller's mounting brackets and push until you hear a click on both sides. Tug gently to confirm the adapter is secure.
- Step 4: Mount the Car Seat: Align the car seat connectors with the adapter latches and lower the seat until it clicks into place. Pull up on the seat to ensure it's locked.
- Step 5: Perform a Safety Check: Tug the car seat in all directions to ensure it's firmly attached, and check that the adapter hasn't loosened. If any wobble is present, reinstall the adapter or seat before use.
