The energy-absorbing foam within the shell adds an extra layer of safety. The seat cushion provides comfort during travel. Finally, locate the instruction manual holder – keep it handy for future reference! Understanding these components is the first step towards safe travels with your little one.
Safety Features Overview
The Graco Nautilus 65 is engineered with multiple safety features. Side-impact tested for enhanced protection, it boasts an integrated steel-reinforced frame for superior strength. The five-point harness secures your child, distributing crash forces effectively.
Energy-absorbing EPS foam lines the headrest and shell, providing crucial impact absorption. Adjustable headrest ensures proper head and neck support as your child grows. A quick-adjust harness system simplifies fitting.
Furthermore, the Nautilus 65 includes anti-rebound bar (in rear-facing mode – if applicable) and a no-rethread harness for effortless adjustments. These features work together to maximize your child’s safety during every ride, offering peace of mind on the road.

Installation Procedures
Proper installation is crucial for safety. This section details how to securely install the Graco Nautilus 65 using LATCH or the vehicle’s seat belt system.
Forward-Facing Installation with LATCH System
Utilizing the LATCH system provides a secure and convenient installation method. First, locate your vehicle’s lower anchors. Connect the Nautilus 65’s lower anchor connectors – these are typically red and click audibly when properly attached. Ensure a snug fit by tightening the LATCH straps.

Next, route the top tether strap to the designated anchor point in your vehicle; consult your vehicle’s manual for its location. Tighten the tether strap to eliminate forward movement of the car seat.
Important: Always confirm the car seat doesn’t move more than one inch side-to-side or front-to-back when tested at the belt path. A properly installed seat will feel firm and stable. Double-check all connections before each use. Remember to never use LATCH if your vehicle or the car seat instructions prohibit it.
Forward-Facing Installation with Vehicle Seat Belt
Installing with the vehicle seat belt is a reliable alternative when LATCH isn’t feasible or preferred. Route the vehicle’s seat belt through the designated belt path on the Nautilus 65 – refer to the car seat’s labeling for correct routing.
Buckle the seat belt and firmly press down on the car seat while simultaneously pulling the shoulder belt to remove any slack. Locking the seat belt is crucial; many vehicles have locking latch plates. Consult your vehicle manual for specifics.
Important: Ensure the car seat doesn’t move more than one inch side-to-side or front-to-back. Utilize the top tether strap for added stability, connecting it to the vehicle’s designated anchor point. Always re-check tightness before each trip.
Rear-Facing Installation (Infant/Toddler Mode)
Rear-facing is the safest position for young children. To install, position the Nautilus 65 at a 45-degree angle. Utilize the recline indicator to achieve the correct angle. Employ either the LATCH system or the vehicle seat belt – never both simultaneously.
When using LATCH, attach the connectors to the vehicle’s lower anchors and tighten the straps. With the seat belt, route it through the correct belt path and lock it securely, following your vehicle’s manual.
Crucially, ensure minimal side-to-side or front-to-back movement (less than one inch). The harness must be at or below the child’s shoulders. Regularly check the installation’s tightness before each journey to maintain optimal safety.

Harnessing and Adjusting the Seat
Secure your child with the five-point harness, ensuring a snug fit. Proper adjustment is vital for optimal safety and comfort during travel.
Adjusting the Harness Height
Proper harness height is crucial for your child’s safety. The Graco Nautilus 65 features multiple harness height positions to accommodate your growing child. To adjust, locate the harness adjustment strap at the top of the car seat’s back.
First, ensure the car seat is not occupied. Press the red release button and simultaneously pull the strap to the desired height. You’ll hear a click when it locks into place. Always verify the harness straps are at or above your child’s shoulders when in rear-facing mode, and at or below their shoulders when forward-facing.
Regularly check and adjust the harness height as your child grows to maintain optimal protection. Incorrect harness height can compromise the car seat’s effectiveness in a crash. Refer to the illustrations in this manual for visual guidance.
Buckling and Unbuckling the Child
Securing your child correctly is paramount. To buckle, open the harness straps and gently place your child in the car seat. Bring the harness straps over your child’s shoulders and insert the bottom buckle tongues into the buckle housing until you hear a distinct ‘click’. Ensure both sides are securely fastened.
To unbuckle, press the red release button on the buckle housing. Both buckle tongues will release simultaneously. Never attempt to unbuckle the harness while the vehicle is in motion. Always check that the harness is completely unbuckled before removing your child from the seat.
A snug fit is essential; tighten the harness straps by pulling on the adjustment strap until you can’t pinch any excess webbing at the shoulder. Regularly check the harness tightness throughout the journey.
Recline Adjustment for Comfort
The Nautilus 65 offers multiple recline positions to ensure your child’s comfort during travel, especially on longer journeys. To adjust the recline, locate the recline handle on the front of the car seat base.
Lift the handle and simultaneously adjust the seat back to the desired position. There are typically several distinct recline settings. Release the handle to lock the seat back into place. Always ensure the recline position is appropriate for your child’s age and size.
For infants, a more reclined position is recommended. As your child grows, you can adjust to a more upright position. Never adjust the recline while a child is seated in the car seat. Confirm secure locking before each trip.

Cleaning and Maintenance
Regular cleaning maintains hygiene and extends the car seat’s life. Follow these guidelines for fabric and plastic components, ensuring safety and longevity.
Fabric Care Instructions
Maintaining the fabric cover is crucial for a comfortable and hygienic ride for your child. The Nautilus 65’s fabric components are generally machine washable, but always check the care label affixed to the seat itself for specific instructions. Typically, you can remove the cover and wash it in cold water on a gentle cycle, using a mild detergent.
Avoid bleach and fabric softeners, as these can damage the material and potentially compromise its safety. After washing, air dry the cover completely. Do not place it in a dryer, as heat can cause shrinkage or damage. Ensure the cover is thoroughly dry before reinstalling it on the car seat. Spot cleaning with a damp cloth and mild soap is recommended for minor spills or stains. For stubborn stains, consult Graco’s customer support for advice.
Plastic Component Cleaning
Keeping the plastic parts clean is essential for maintaining the overall hygiene of the Graco Nautilus 65. To clean these components, simply use a damp cloth with a mild soap solution. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the plastic and potentially affect the car seat’s structural integrity.
Pay particular attention to areas where dirt and grime accumulate, such as around the buckle, harness straps, and the seat shell. Rinse the cloth thoroughly with clean water after applying the soap, and wipe down the plastic surfaces to remove any residue. Ensure all cleaning solutions are completely wiped away before allowing your child to use the car seat. Never submerge the car seat in water or any other liquid. Regular cleaning will help prolong the life of your Nautilus 65.

Troubleshooting Common Issues
Encountering problems? This section provides solutions for frequently asked questions and common difficulties experienced with your Graco Nautilus 65 car seat.
Harness Strap Tangling
Dealing with tangled straps? It’s a common frustration! Often, harness straps can become twisted or difficult to manage, especially during installation or when adjusting the fit. First, ensure the harness is fully extended. Gently work the straps, separating any twists near the buckle and shoulder slots.
Avoid forcing the straps; instead, use a smooth, deliberate motion. If tangling persists, completely remove the harness from the buckle and re-thread it, verifying it’s correctly positioned in the slots. Regularly check the straps before each use to prevent tangles from developing. A small amount of silicone spray (specifically designed for car seats – always check Graco’s guidelines first!) can sometimes help with smoother operation, but use sparingly.
Remember, a properly functioning harness is crucial for safety!
Installation Difficulties
Experiencing trouble securing the Nautilus 65? Don’t compromise on safety! If you’re struggling with installation, double-check the vehicle’s seat compatibility – not all vehicles are created equal. Ensure the LATCH connectors are firmly attached to the anchor points, and the vehicle seat belt is locked.
Refer back to the detailed installation instructions for both forward-facing and rear-facing modes. If using the LATCH system, verify you haven’t exceeded the vehicle’s LATCH weight limit. For seat belt installation, confirm the belt lies flat and isn’t twisted.
If issues persist, consult the Graco customer support team or a certified Child Passenger Safety Technician (CPST) for assistance. A secure installation is paramount!

Safety Reminders and Warnings
Always adhere to weight and height limits; never modify the car seat; Regularly inspect for damage and replace after any accident or expiration;
Weight and Height Limits
Understanding the weight and height limits is crucial for your child’s safety. The Graco Nautilus 65 is designed to accommodate children ranging from 22 to 65 pounds in forward-facing mode with a harness. Height limits are up to 49 inches.

For rear-facing use (infant/toddler mode), the Nautilus 65 supports children from 5 to 40 pounds and up to 40 inches in height. Never exceed these limits, as doing so compromises the seat’s protective capabilities.
Regularly check your child’s weight and height against these specifications. As your child grows, adjust the harness and recline accordingly. If your child reaches the maximum weight or height limit, it’s time to transition to a booster seat appropriate for their size and age. Prioritize safety and follow these guidelines diligently.
