Base Installation: Step-by-Step
Securely installing the Chicco KeyFit 35 base is paramount for your child’s safety. Begin by locating the lower anchor connectors or the vehicle’s seat belt path‚ as detailed in your vehicle’s owner’s manual. Ensure the base is positioned correctly‚ following the angle indicator for proper recline.
Attach the lower anchors or thread the seat belt through the designated path‚ tightening it firmly.

Finally‚ double-check all connections and ensure the base is locked into place. Always refer to the User Guide for specific instructions tailored to your vehicle and the KeyFit 35 model. A properly installed base provides a secure foundation for your infant car seat.
Installation Without the Base
Installing the Chicco KeyFit 35 directly with the vehicle’s seat belt offers flexibility. Begin by positioning the car seat securely on the vehicle seat‚ ensuring it’s facing the correct direction. Thread the vehicle’s seat belt through the designated belt path on the car seat‚ as illustrated in the User Guide.
Lock the seat belt – consult your vehicle’s manual for locking instructions – and tighten it firmly‚ eliminating any slack. Verify the car seat doesn’t move more than one inch side-to-side or front-to-back. Pay close attention to the recline angle; it must be within the acceptable range indicated on the car seat.
Remember to always refer to the manual for detailed instructions and vehicle-specific guidance. Watch the Chicco video for a visual demonstration of this process. Proper installation without the base is vital for your child’s safety.
Leveling the Car Seat
Achieving the correct recline angle is crucial for infant safety when using the Chicco KeyFit 35. The User Guide provides specific indicators to ensure proper leveling‚ whether installed with or without the base. Utilize the recline indicator located on the car seat itself; it should show within the designated range.
Incorrect leveling can compromise the car seat’s protective capabilities. If the angle is too steep or too shallow‚ adjust the recline mechanism according to the manual’s instructions. Ensure the car seat remains stable and doesn’t shift after adjustment.
Remember‚ the Child Restraint must be properly leveled. Regularly check the recline angle‚ especially after installation or any adjustments. A properly leveled car seat provides optimal protection during travel.

Proper Use of the Harness System
The KeyFit 35’s harness system is crucial for your child’s safety; therefore‚ correct usage is paramount. Always ensure the harness straps are positioned correctly – at or below your child’s shoulders in rear-facing mode. The harness should lie flat‚ without any twists.
Securely fasten the harness‚ ensuring it’s snug but not overly tight. You should not be able to pinch any excess webbing at the shoulder. Utilize the chest clip at armpit level to properly position the straps. Regularly check the harness tightness as your child grows.

Recline Adjustment
The KeyFit 35 offers recline adjustment to ensure proper installation and comfort for your baby. Refer to the manual for detailed instructions‚ as correct recline is crucial for infant positioning and safety. The recline indicator is a vital tool for achieving the correct angle.

Release the handle to lock the recline. Always verify the recline indicator displays a proper installation angle – usually indicated by a blue or green zone.
Newborns require a more reclined position‚ while older infants can use a more upright position. Incorrect recline can compromise the car seat’s ability to protect your child in a crash. Regularly check the recline angle‚ especially after adjustments or movement of the car seat.
Harness Height Adjustment
Proper harness height adjustment is essential for your child’s safety and comfort within the KeyFit 35. The manual provides detailed instructions on how to correctly adjust the harness as your baby grows. Incorrect height can compromise the car seat’s protective capabilities.
