Key Features
SensorSafe Technology
The SensorSafe technology is integrated into the chest clip of the car seat, providing critical alerts to parents when unsafe situations arise. This includes alerts for unbuckling, prolonged seating, and temperature extremes within the vehicle.

Linear Side-Impact Protection (L.S.P. System)
The individually adjustable Linear Side-Impact Protection (L.S.P. System) is designed to absorb up to 25% more impact forces in the event of a side collision, enhancing child safety.

Adjustable Headrest and Harness System
The car seat features a patented 3-position reclining headrest that helps prevent the child's head from falling forward while asleep, guiding the head and neck into a safe position. The 12-position height-adjustable headrest with an integrated harness ensures a proper fit as your child grows.

In-Seat Recline
The 10-position recline angle provides correct ergonomic positioning and extra legroom, allowing your child to safely ride rear-facing for longer periods. The 6-position reclining backrest offers one-hand recline for both rear-facing and forward-facing installations.

Removable Newborn Inlay
For very small babies, a removable newborn inlay provides additional support and a snug fit, ensuring proper positioning and comfort.

Magnetic Buckle Holders
Magnetic buckle holders keep the harness straps out of the way, making it easier to place and remove your child from the car seat.

Rear-Facing Mode
Suitable for infants from 4 lbs up to 50 lbs. Ensure the car seat is installed at the correct recline angle, indicated by the dual level indicators, and securely fastened using either the LATCH system or the vehicle's seat belt. Refer to the full user manual for detailed LATCH and seat belt installation steps.
Forward-Facing Mode
Suitable for children from 22 lbs up to 65 lbs. The car seat must be installed using the vehicle's seat belt and top tether. Ensure the harness is properly adjusted to fit your child snugly.
Belt-Positioning Booster Mode
Suitable for children from 40 lbs up to 120 lbs. In this mode, the car seat uses the vehicle's seat belt to secure the child. The car seat's headrest should be adjusted so the vehicle's shoulder belt rests correctly across the child's shoulder.
Operating the Car Seat
Adjusting the Harness
To adjust the harness height, squeeze the headrest adjustment lever and slide the headrest up or down until the shoulder straps are at or just above your child's shoulders for forward-facing, or at or just below for rear-facing. To tighten the harness, pull the adjustment strap located at the front of the seat. To loosen, press the harness release button while pulling the shoulder straps forward.
Recline Adjustment
The car seat offers multiple recline positions. To recline the seat, locate the recline lever (usually at the front or side of the base) and pull it while simultaneously pushing or pulling the car seat to the desired angle. Ensure the recline indicator is within the acceptable range for your chosen installation mode.
Headrest Adjustment
The headrest can be adjusted to 12 positions. To adjust, squeeze the headrest adjustment lever located at the top of the headrest and slide it up or down. Ensure the headrest is positioned correctly for your child's height, aligning the shoulder straps as described above.
Maintenance and Care
- Fabric Covers: The fabric covers are removable and machine washable on a delicate cycle with cold water. Air dry only. Do not bleach or tumble dry.
- Plastic Parts: Wipe plastic parts with a damp cloth and mild soap. Do not use abrasive cleaners or solvents.
- Harness System: Wipe the harness straps with a damp cloth. Do not machine wash or immerse the harness straps in water, as this can weaken the webbing.
- Buckle: Periodically check the buckle for debris. Clean with a damp cloth if necessary.
Troubleshooting Common Issues
- Car Seat is Loose After Installation: Ensure the LATCH connectors or vehicle seat belt are pulled as tightly as possible. Apply pressure to the car seat while tightening. Check the recline angle using the dual level indicators.
- Harness is Difficult to Tighten/Loosen: Check for any twists in the harness straps behind the car seat. Ensure no fabric is obstructing the harness path.
- SensorSafe Alerts: Refer to the SensorSafe app for specific alert details and recommended actions. Ensure the SensorSafe app is properly installed and connected to the chest clip.
- Child's Head Falls Forward While Asleep: Adjust the patented reclining headrest to one of its three positions to better support the child's head and neck.
