5. Operating Modes
The Graco Nautilus 2.0 LX offers three distinct modes to accommodate your child's growth.

Image 5.1: The three modes of use for the Graco Nautilus 2.0 LX car seat.
5.1. Forward-Facing Harness Mode
Use this mode for children weighing 26.5-65 lb. Ensure the 5-point harness is properly adjusted and snug against your child's body. The chest clip should be at armpit level.
5.2. Highback Booster Mode
For children weighing 40-100 lb. In this mode, the car seat's internal harness is removed, and your vehicle's lap and shoulder belt are used to secure your child. Ensure the shoulder belt lies flat across the center of your child's shoulder and chest, and the lap belt is low on the hips, touching the thighs.
5.3. Backless Booster Mode
For children weighing 40-120 lb. The backrest of the car seat is removed, and only the booster base is used. Your vehicle's lap and shoulder belt are used to secure your child, following the same guidelines as the highback booster mode.
6. Maintenance
Regular cleaning and maintenance will help prolong the life of your car seat.
- Seat Pad: The seat pad is machine washable. Refer to the care tag on the pad for specific washing instructions. Use cold water and a gentle cycle. Drip dry. Do not use bleach.
- Harness Straps: Wipe harness straps with a damp cloth. Do not machine wash or immerse in water, as this may weaken the straps.
- Buckle: Clean the buckle by placing it in a cup of warm water and gently agitating it. Do not use soaps or detergents.
- Plastic and Metal Parts: Wipe with mild soap and cool water.
7. Troubleshooting
If you encounter issues with your Graco Nautilus 2.0 LX car seat, consider the following common solutions:
- Difficulty Tightening Harness: Ensure the harness straps are not twisted. Check that no fabric or clothing is obstructing the harness path.
- Loose Installation: Re-read the installation instructions carefully. Ensure the LATCH connectors are fully engaged and the strap is pulled tight while pressing down on the car seat. Verify that the car seat does not move more than 1 inch at the belt path.
- Buckle Sticking: Clean the buckle as described in the Maintenance section (Section 6). Avoid food debris or liquids entering the buckle mechanism.
For persistent issues or concerns, contact Graco customer support.
