• Use REAR-facing for children who weigh between 5 and 50 lb (2.3 and 22.7 kg).
• Use FORWARD-facing with a harness for children who weigh between 22 and 65 lb (10 and 29.5 kg).
• Use in BOOSTER mode only with children who weigh between 40 and 120 lb (18.1 and 54.4 kg) and whose height is between 44 and 63 in (111.8 and 160 cm).

INSTALLATION

• Secure the top tether strap provided with this child restraint for FORWARD-facing harness mode.
• Car seat base MUST be flat on vehicle seat and MUST be parallel to vehicle seat.
• Snugly adjust the belts provided with this child restraint around your child.
• Use only the vehicle's lap and shoulder belt system when restraining the child in this BOOSTER seat. Never secure a child with a lap belt only in BOOSTER mode.
• Use only the "B" recline position when using child restraint in BOOSTER mode.
• For models with anti-rebound bar, the anti-rebound bar MUST be removed for FORWARD-facing.

GENERAL USE

• Secure this child restraint with the vehicle's child restraint anchorage system, if available, or with a vehicle seat belt.
• Register your child restraint with the manufacturer.
• The headrest cover MUST be unfolded for children weighing 9.1 kg (20 lb) or more.
• The provided infant position pillow MUST be removed for children weighing 9.1 kg (20 lb) or more.
• For models WITH storage pouch only: When not in use, the lower anchor adjuster and strap MUST be stored in the storage pouch inside of the seat.
• For models WITHOUT storage pouch only: When not in use, the lower anchor adjuster and strap MUST be rolled and secured.
• The primary protection for occupants of a vehicle in a collision is the body of the vehicle itself; a child seat will not protect a child when a vehicle is seriously impacted. However, correctly installed, a child seat will substantially improve chances for survival in most crashes. Make sure all users fully understand the correct ways to use this child seat in a vehicle.

Important Notes

• Britax strongly recommends that children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed.
• To prevent injury due to deterioration or hidden damage, discontinue use of this child restraint if it is older than ten (10) years. See the Serial Number and Manufactured Date Label on the child restraint.
• Before each use, check this child restraint and its components to make sure they are in good condition and good working order.
• Discontinue use of this child restraint if it has been in a moderate or severe crash. It is not necessary to replace a child restraint after a minor crash, defined by the US National Highway Traffic Safety Administration (NHTSA) as:
  1. The vehicle is drivable from the crash site; and
  2. The vehicle door nearest to the child restraint was not damaged; and
  3. No vehicle occupants were injured; and
  4. There is no visible damage to the child restraint; and
  5. The airbags (if present) did not deploy.
• ALWAYS make sure the child restraint system is secured to the vehicle, even when unoccupied, since in a crash, an unsecured child restraint system may injure occupants.
• Verify that the child restraint and child restraint belts or straps do not interfere with the opening and closing of the vehicle door.
• Consult vehicle user guide to ensure child restraint installation does not interfere with function of vehicle seats.
• Snugly adjust the belts provided with the child restraint around your child.
• Ensure the lower harness (waist) straps are firmly adjusted in a position so that the child's pelvic area is secure.
• Ensure the upper harness (shoulder) straps are firmly adjusted so that the child is secure.
• The use of non-Britax covers, inserts, toys, accessories or tightening devices is not approved by Britax. Their use could cause this child restraint not to perform as intended in a crash.
• Cover the child restraint when the vehicle is parked in direct sunlight. Metal parts of child restraint could become hot enough to burn a child.
• Store the child restraint in a cool and dry place when it is not being used. Avoid placing heavy objects on top of it.
• Do not attempt to disassemble any part of the child restraint or change the way the harness or vehicle's seat belts are used, except as described in this booklet.
• NEVER use the harness adjuster strap to lift or carry this child restraint. Doing so could cause damage to harness adjuster and webbing. Always carry this child restraint by its shell or carry handle.
• In a vehicle with rear designated seating positions, vehicle owners should be alerted that, according to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating positions. To ensure your child's safety, please study Vehicle Seating Positions and consult your vehicle owner's manual.
• Third party recommendations are subject to change, so we recommend you visit their websites for the most up to date recommendations.

Vehicle Compatibility Guidelines

Vehicle Buckle Positions

The position of the vehicle belt buckle can adversely affect the stability of the child restraint.

If the vehicle buckle lies near the incorrect position ( ) when the vehicle belt is tightened, try fitting the child restraint in another seating position in the vehicle. If it is not possible to achieve the correct position ( ) for the vehicle buckle, then another seating position MUST be used.

Vehicle Seating Positions

DO NOT place child seat REAR-facing in the front seat of a vehicle with a passenger air bag. DEATH or SERIOUS INJURY can occur. Owners of vehicles with front passenger side airbags should refer to their owner's manual for child restraint installation instructions. The back seat is the safest place for children 12 and under.

Some vehicles have no seating positions which are compatible with this child seat. If in doubt, contact the vehicle manufacturer for assistance.
Forward-facing vehicle seats MUST be used with this child seat. Side-facing or rear-facing seats CANNOT be used. See the diagram below.

Vehicle Headrest

In some cases, the vehicle headrest can prevent the child restraint headrest from being raised high enough to properly adjust the harness for the fit of your child when using a FORWARD-facing reclined position. DO NOT force the child restraint headrest past the vehicle headrest.
Doing so could cause the child restraint not to perform as intended. If the location of the vehicle headrest interferes with the child restraint headrest, raise or remove the vehicle headrest. If the vehicle headrest can not be removed, move the child restraint to the upright position or try a different seating location.

Incompatible Vehicle Seat Belts

The following types of vehicle seat belts are NOT compatible with this child restraint. If any of the belt types listed below are in the chosen seating position, choose another vehicle seating position or check your vehicle owner's manual for information on installing a car seat in your vehicle.

Lap belts with a sewn-in latch plate that have a retractor that locks only in case of a sudden stop.

Lap belts forward of the vehicle seat bight.

Lap-shoulder belts with top or bottom anchor points on the vehicle door.

Motorized, automatic vehicle seat belts.

NOTE: This Britax child restraint may not be compatible with every inflatable lap-shoulder belt. See FAQs in the support section of the Britax website (us.britax.com/faqs) for additional instructions.

Using the Lower Anchors and Tethers for Children

The Lower Anchors and Tethers for Children or LATCH, is a system available on this child restraint that offers an alternative to vehicle seat belt installation methods. The figure below shows typical locations for lower anchors and tether anchors in a vehicle. See Features Overview for LATCH components on this child restraint.

Check your vehicle owner's manual to learn if it is equipped with LATCH, the maximum weight rating for the lower anchors, tether anchors capacities, and information on the lower anchor locations and designated seating positions available for use with this child restraint.

Tether anchor locations vary from vehicle to vehicle. Check your vehicle owner's manual and look for the tether anchor symbol shown in the diagram to help identify where the top tether anchor point is located in your vehicle.

Overhang from Vehicle Seat

Harness Mode

It is important that the base of the child restraint rests completely flat on the vehicle seat with no side overhang. It is permissible to allow up to 3 in. (7.5 cm) of the base to hang over the front edge of the vehicle seat. If the vehicle seat does not allow enough of the child restraint base to make contact, adjust the recline angle to a more upright position. Not doing so could cause the child restraint to not perform as intended.

Car seat base MUST be flat on vehicle seat and MUST be parallel to vehicle seat.

Booster Mode

Overhang is not allowed in BOOSTER mode. In BOOSTER mode, the base of the child restraint must fit completely on the vehicle seat.

BOOSTER Mode Installation

Britax strongly recommends that children should remain in a child seat with a 5-point harness until reaching the maximum weight or height allowed.

Use in BOOSTER mode only:

• in recline position "B", and
• with children who weigh 40 - 120 lb (18.1 - 54.4 kg), and
• when top of child's ears are BELOW the top of headrest, and
  
• when the lap belt sits low across child's upper thighs when routed through the belt guide, and
• when the vehicle shoulder belt lays straight across the child's chest, and
• when the shoulder belt guides are positioned above the child's shoulders.

Using Lower Anchors and Top Tether in BOOSTER Mode
Use of lower anchors and top tether is not required for booster seat installation. However, lower anchors and top tether can be used to secure child restraint in BOOSTER mode. ALWAYS make sure the child restraint system is secured to the vehicle, even when unoccupied, since in a crash, an unsecured child restraint system may injure occupants.

To use this seat in BOOSTER mode without lower anchors, see instructions for Securing Your Child in BOOSTER Mode.

1. Refer to section Switching between Harness and Booster Mode to convert from harness to BOOSTER mode.
2. Adjust the child restraint to position "B" by pushing the red recline button on either side of the base.
   
3. Extend the top tether strap by lifting on the top tether adjuster.

7. Extend lower connector strap to its longest length by pressing the grey button on adjuster.
   
8. Place child restraint on the vehicle seat so that the car seat base is flat on the vehicle seat and is parallel to vehicle seat.
   NOTE: If your vehicle seat back is adjustable, ensure it is in the upright position before placing the child seat on the vehicle seat.
   
9. Ensure the base does not hang over front edge of vehicle seat.
10. Route the lower connector strap through the FORWARD-facing belt path marked by green labels. Firmly press the lower connectors onto their adjacent lower anchors.
    
11. Ensure the connector strap is not twisted and remove slack.
    
12. Close the CLICKTIGHT over the lower connector strap.
    
13. Ensure both CLICKTIGHT release buttons are visible.
    NOTE: If it is difficult to close, you may have removed too much slack.
    
14. Connect the top tether hook to the vehicle's top tether anchor (check the vehicle owner's manual for location).
    
15. Pull the top tether strap to remove slack and secure excess webbing with the elastic band attached.
