General Warnings
This child seat must not be used in the home, in boats, or other•
non-certified applications.
To prevent injury due to deterioration or hidden damage,•
discontinue use of this child seat that is older than nine years or
has been in a moderate or severe crash. See date of manufacture
and expiration date located on child seat shell.
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 the vehicle is seriously impacted. However, correctly
installed, a child seat will substantially improve the chances for
survival in most crashes.
Cover the child seat when the vehicle is parked in direct sunlight.•
Parts of the child seat can become hot enough to burn a child.
Secure this child seat even when it is not occupied. In a crash, an•
unsecured child seat may injure vehicle occupants.
Store the child seat in a safe place when it is not being used. Avoid•
placing heavy objects on top of the child seat.
Never use the harness or adjuster strap to lift or carry this child•
seat. Doing so could damage the harness adjuster and webbing.
Always carry this child seat by the shell or tether straps.
Do not allow children to play with this child seat.•

is right-side up and that the
LATCH strap is not twisted before
connecting.
NOTE: The LATCH connectors will click when properly attached.
IMPORTANT: Refer to your vehicle owner’s manual or contact the vehicle
manufacturer for the maximum weight rating for their LATCH anchors.
Use the vehicle belt (not LATCH) for installations with children who weigh
more than the vehicle LATCH anchor limit. Unless specified otherwise by
the vehicle manufacturer, assume a 40 pound (18.1 kg.) child is the vehicle
LATCH anchor limit. Only use the vehicle’s designated tether anchor for the
chosen seating position.
Using the Versa-Tether
WARNING:
Attach the Versa-Tether only to tether anchors identified by your vehicle•
manufacturer as tether anchorage points.
If your vehicle does not currently have a tether anchor attachment, refer to your•
vehicle owner’s manual or contact your vehicle manufacturer for assistance. DO
NOT modify your vehicle without advice from your vehicle manufacturer.
When using the child seat in harness mode:
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.
Always use the Versa-Tether for children weighing 65 – 80 lbs (29.5 – 36.3 kg).•
IMPORTANT: You must use the Versa-Tether if installing the child seat

Based on crash statistics, the National Highway Traffic Safety
Administration recommends that parents select a rear seating position
as the safest location for a properly installed child seat. The back seat
is the safest place for children 12 and under.
Please study Understanding Vehicle Seat Belts on page 18 of this
booklet to ensure the child’s safety. If in doubt about installing the
child seat, consult the vehicle owner’s manual.
Vehicle Compatibility
WARNING:
A forward-facing child seat in the front seat of a vehicle with a•
passenger air bag is not recommended. DEATH or SERIOUS INJURY
can occur.
When using this child seat in a vehicle with air bags, refer to the•
vehicle owner’s manual for child seat installation instructions and
precautions.
WARNING: Forward-facing vehicle seats MUST be
used with this child seat. Side-facing or rear-facing seats
CANNOT be used.

Vehicle Seating Positions

18
Vehicle seat belts and LATCH
anchor locations vary. Consult
your vehicle owner’s manual
for details on what type of
seat belts your vehicle has and
where to find your LATCH
anchors (if available).
Vehicle Compatibility
IMPORTANT: Refer to your vehicle owner’s manual or contact the vehicle
manufacturer for the maximum weight rating for their LATCH anchors.
Use the vehicle belt (not LATCH) for installations with children who weigh
more than the vehicle LATCH anchor limit. Unless specified otherwise by
the vehicle manufacturer, assume a 40 pound (18.1 kg.) child is the vehicle
LATCH anchor limit. Only use the vehicle’s designated tether anchor for the
chosen seating position. Do not connect more than one LATCH anchor or
tether hook to a single vehicle anchor.
Understanding Vehicle Seat Belts
NOTE: The information in this section only applies to installation with
vehicle safety belts.
This child seat can fit securely in most vehicles using existing vehicle
belts; however, some vehicle designs prevent a secure fit of the child
seat due to the position of the vehicle belt lower anchorage points.
WARNING: Use only the vehicle’s lap and shoulder belt system
when restraining a child in booster mode. Never restrain a child
with a lap belt only in booster mode.
