Important Child Seat Usage Information

Rear-Facing: 2.3 – 18.1 kg (5 – 40 lbs)

American Academy of Pediatrics recommends: All infants and toddlers should ride in a Rear Facing Car Seat until they are 2 years of age or until they reach the highest weight or height allowed by their car safety seat’s manufacturer.

Britax strongly recommends that children ride rear-facing to the highest weight or height specified.

WARNING! REAR-FACING use of this child seat is

ONLY for children who meet ALL of the following requirements.

If the child cannot be secured within these requirements because they are too small, use of the infant positioning insert or selection of a different child seat (such as an infant car seat) may be required. If the child cannot be secured within these requirements because the child is too large, review the forwardfacing guidelines on page 5.

An infant positioning insert may be necessary for small infants to achieve a snug fit if the child is under 5.4 kg (12 lbs) and the lowest harness slots fall above the infants shoulders. The infant

positioning insert is sold separately at select retailers and on www. britaxusa.com.

The included infant body pillow may be used to achieve better fit and support for smaller infants. See page 15.

Use rear-facing with children:

• who weigh between 2.3 and 18.1 kg

(5 – 40 lbs) and

• when the top of the child’s head is at least 2.5 cm (1 in.) below the top of the child seat shell (Fig. A) and

• when the harness straps are at or slightly below the child’s shoulders (Fig. A).

IMPORTANT: See Adjusting the Harness Height on page 12.

WARNING! FORWARD-FACING use of this child seat

is ONLY for children who meet ALL of the requirements below. If the child cannot be secured within these requirements because they are too large, another type of child seat (such as a booster) may be required. If the child cannot be secured within these requirements because the child is too small, review the rear-facing information above.

Forward-Facing: 10 – 29.5 kg (22 – 65 lbs) and are able to walk unassisted

Using the Lower Universal Anchorage System (LUAS)

The Lower Universal Anchorage System or LUAS, is a system available on this child seat that offers an alternative to vehicle seat belt installation methods. See pages 10 and 11 for LUAS components on this child seat.

The figure above shows typical locations for lower anchors and tether anchors in a vehicle. Check your vehicle owner’s manual to learn if it is equipped with LUAS, the maximum weight rating for the lower anchors, and for information on the lower anchor locations and seating positions available for use with this child seat.

Standard vehicle seat spacing between LUAS anchors is 27.9 cm (11 in.). This child seat can be used in a seating position with up to 50.8 cm (20 in.) of space between the LUAS anchors if the vehicle manufacturer allows.

To remove the lower connector from the storage slot or lower anchor:

1 Press and hold the red release

button.

2 Pull the lower connector from the

storage slot or lower anchor.

Using the Energy-Absorbing Versa-Tether

WARNING! Failure to follow the guidelines below may

cause the child seat not to perform as intended:

• You MUST always use the Versa-Tether when using the child seat forward-facing. Using the tether will improve the stability of your child seat and reduce the risk of injury.

• Attach the Versa-Tether only to tether anchors identified by your vehicle manufacturer as tether anchorage points. Only use the designated tether anchor for each seating position.

• If your vehicle does not currently have a tether anchor attachment, refer to your vehicle owner’s manual or contact your vehicle man u fac tur er for assistance. DO NOT modify your vehicle without advice from your vehicle manufacturer.

• Store the Versa-Tether in the pouch on the back of the child seat when not in use. DO NOT install the child seat with the Versa-Tether attached to the carry clip.

WARNING! In some cases, the vehicle

head restraint can prevent the child seat head pad 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 seat head pad past the vehicle head restraint. Doing so could cause the child seat not to perform as intended. If the location of the vehicle head restraint interferes with the child seat head pad, raise or remove the vehicle head restraint. If the vehicle head restraint cannot be removed, move the child seat to the upright position or try a different seating location.

18 19

The Versa-Tether can indicate when the child seat has been in a moderate or severe crash (see page 3) and replacement of the child seat is necessary.

Figure 1 shows a tether acceptable for continued use (provided the child

seat has not been involved in a crash). The colored stitching will be

intact and not visible from the back of the seat.

Figures 2 and 3 show examples of when the tether has been damaged and is unacceptable for continued use. If one or both of the loops have pulled through the back of the shell and/or any of the colored stitching has ripped, the child seat is no longer acceptable for use.

IMPORTANT: Discontinue use of child seat if it has been involved in a moderate or severe crash, regardless of whether the loops have pulled through the back side of the shell and the colored stitching has been ripped.

Child Seat FunctionsChild Seat Functions

Rear-Facing Tether Connector Strap

Because every vehicle model is different, locations to anchor the tether for rear-facing installations may vary. Use the rear-facing tether connector strap (only configuration “A” above) to assist in creating an anchor point.

1 Find a fixed location in the vehicle that is bolted

to the floor.

* If you cannot find a location to create an

anchor point, contact the vehicle manufacturer to identify a tether connection point.

2 Route the strap through the anchor

point.

3 Thread the metal D-ring through the

loop on the end of the strap.

4 Pull the metal D-ring through until

the strap is tight.

5 Use the D-ring as an attachment

point for the tether.

NOTE: Store the tether connector strap in the tether pouch when not in use.

IMPORTANT: The Versa-Tether® carry clip is only for use when you wish to carry the child seat between locations.

Do not install the child seat with the Versa-Tether attached to the carry clip. Secure the excess Versa-

Tether webbing in the elastic strap during use. Store the Versa-Tether in the storage pouch when not in use. Always ensure any excess webbing is contained within your vehicle.

To attach the Versa-Tether to the carry clip or tether anchor:

1 Firmly press the hook over

the carry clip or tether anchor point.

2 Pull the loose end of the

webbing to remove slack from the Versa-Tether.

NOTE: When using as a carry strap, tighten until the strap is comfortable to carry.

To remove the Versa-Tether from the carry clip:

1 Loosen the Versa-Tether.

a Tilt the lock up b Pull the tether webbing

2 Remove the Versa-Tether®

hook from the carry clip.

Attaching the Versa-Tether

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 points are located in your vehicle. Britax recommends that the tether be used at all times when installing the child seat. Using the tether will improve the stability of your child seat and reduce the risk of injury. See the diagrams below for possible rearand forward-facing Versa-Tether installation configurations.

Install with the LUAS as shown above.

Before You Begin:

• Check that your vehicle has lower anchors.

* Refer to your vehicle owner’s manual or contact the vehicle

manufacturer for the maximum weight rating for their lower anchors. Use vehicle belt (not lower connectors) for installations with children who weigh more than the vehicle lower anchor limit. Unless specified otherwise by the vehicle manufacturer, assume an 18.1 kg (40 lb) child is the vehicle lower anchor limit.

• Remove the lower connectors from the storage slots in the base. Press the adjuster release button and pull the strap to full length. Repeat for the second strap.

• Recline this child seat to position 3 and place rear-facing on the vehicle seat (see page 15).

* When properly installed in the rear-facing

position, the back angle of the child seat

should be at least 30˚ for children and up to 45˚ from vertical for infants unable to

maintain head and neck control (not to

exceed 45˚) when the car is parked on a

level surface. Use the blue line as a guide to achieve the proper recline angle for rearfacing installations. The blue line will be parallel to the ground when the child seat angle is at the center of the angle range

(30 – 45˚). If necessary, the proper recline angle can be achieved

by placing a rolled towel or pool noodle in the vehicle seat bight.

• Britax recommends that the Versa-Tether is used at all times. Using the tether will improve the stability of the child seat and reduce the risk of injury. Check your vehicle owner’s manual for tether anchor locations. See page 18 for possible rear-facing tether configurations.

LUAS Installation

1 Firmly press the lower

connectors onto the adjacent lower anchors.

• A click confirms attachment.

• Verify that the lower connector strap is not twisted.

TIP: You may need to turn the front

of the child seat toward you for easier access to the lower anchors.

NOTE: If a click is not heard when connecting either lower connector, the lower connector strap may be twisted, or there may be debris in the lower connector. Correct either situation before continuing with the installation process.

Push the child seat down while pulling each lower connector strap to tighten.

3 Rear-facing installations can

be improved by the use of the Versa-Tether (see pages 17 – 19).

Checklist

9 Check that all connections are secure. 9 Check that the lower connector straps are not twisted. 9 Check that the child seat cannot be moved front to back or side to side

more than 2.5 cm (1 in.) at the belt path. If the child seat is not secure, repeat installation or use a different seating location.

9 Check that the back angle of the child seat is 30º – 45º from vertical

(not to exceed 45º) when the car is parked on a level surface.

* If necessary, the proper recline angle can be achieved by

placing a rolled towel or pool noodle in the vehicle seat bight.
