• 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 on page 57 and consult
your vehicle owner’s manual.
• NEVER leave child unattended.
• The use of non-Britax covers, inserts, toys, accessories, or
tightening devices is not approved by Britax. Their use could
cause this child seat not to perform as intended in a crash.
• ALWAYS check the back seat upon leaving your vehicle to prevent
leaving a child restrained in the infant car seat alone in the
vehicle.
• Suffocation Hazard: Infant carrier can roll over on soft surfaces
and suffocate child. NEVER place carrier on beds, sofas, or other
soft surfaces.
• Fall Hazard: Child’s activity can move carrier. NEVER place carrier
on counter tops, tables, or any other elevated surface.
• Fall Hazard: The carrier can fall from the shopping cart.
DO NOT use on shopping carts.
• Fall Hazard: NEVER use this child restraint on boats, low
speed vehicles (LSV), all-terrain vehicles (ATV), golf
carts, or any other non-certied application.
• Strangulation Hazard:
Children have STRANGLED in
loose or partially buckled harness straps. Fully restrain the child
even when carrier is used outside the vehicle.

8
• ALWAYS lift infant car seat by both sides of carry handle after
installation in base to verify that it is secure.
• DO NOT use the infant carrier if it is damaged or broken.
• To prevent injury due to deterioration or hidden damage, DO NOT
use this infant car seat and base if it is older than six (6) years or
has been in a moderate or severe crash. See expiration date on
the date of manufacture label located on the infant car seat and
base.
• 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.
• 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.
• Do NOT route belt(s) through ClickTight
handle opening for any installation
method.

Important Notes
• Discontinue use of this child seat if it has been in a moderate
or severe crash. It is not necessary to replace a car seat after a
minor crash dened by the U.S. National Highway Trafc Safety
Administration (NHTSA) as:
a. The vehicle is drivable from the crash site; and
b. The vehicle door nearest the child seat was not damaged;
and
c. No vehicle occupants were injured; and
d. There is no visible damage to the child seat; and
e. The airbags (if present) did not deploy.
• 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.
• Ensure the lower harness (waist) straps are rmly adjusted in a
position so that the child’s pelvic area is secure.
• Ensure the upper harness (shoulder) straps are rmly adjusted so
that the child is secure.
• Never leave child unattended.
• Do not, except as described in this booklet, attempt to
disassemble any part of the child seat or change the way the
harness or vehicle’s seat belts are used.

10
• Do not allow children to play with this child seat.
• Do not use anything to raise the child seat off vehicle seat except
as described in these instructions. In a crash, this could cause the
child seat not to perform as intended.
• Store the infant car seat in a safe, dry place when it will not be
used for an extended period of time. Do not place heavy objects
on top of it.
• Third party recommendations are subject to change, so we
recommend you visit their websites for the most up to date
recommendations.
