WARNING
DEATH OR SERIOUS INJURY CAN OCCUR
• Follow all instructions labeled on this child restraint and in
the written instruction manual on the lanyard located on
back of restraint. For infants under 4.5 kg (10 lbs), consult
pediatrician for recommended seat back angle before
installation.
• Failure to follow all instructions and product labels can
result in death or serious injury in a crash. Carefully read
and understand this instruction manual prior to using
restraint. If you have any questions, visit www.diono.com
or contact Diono at 519-725-1700.
• Use only with children weighing between 5 lbs to 100 lbs
(2.3 kg to 54 kg) and who have a height of 57 inches (144
cm) or less.
• Use only in rear-facing position with any infant weighing
less than 22 lbs (10 kg) and between 18–30 inches
(46–76cm).
• For children rear-facing: 5–40 lbs and 18–44 inches (2.3–
18 kg and 46–112 cm)
Forward-facing with harness: 22–65 lbs and 30–57 inches
(10–30 kg and 76–144 cm)
Booster mode: 50–100 lbs (23–45 kg) and 40–57 inches
(101–144 cm)
• Only secure this child restraint with the vehicle’s lower
universal anchorage system (UAS) if available or with
vehicle seat belt.
• Do not use vehicle’s lower universal anchorage system
when installing this restraint for a harnessed child
weighing more than 65 lbs (30 kg).
• Always use the top tether strap when installing this
restraint forward-facing.
• Always use the SafeStop™ device according to manufac-
turer’s instructions.
• Always use a locking clip if it is required for proper
restraint installation. Consult vehicle owner’s manual.
• WARNING: Before installing restraint in a vehicle
equipped with front passenger airbags, carefully read the
vehicle owner’s manual for proper restraint installation
instructions.
• Some vehicles have passenger seating in which the
passenger faces the side or the rear of the vehicle. Do not
install this restraint in such passenger seating. Only use
this restraint in a vehicle seat which faces an adult
passenger toward the front of the vehicle.

WARNING
DEATH OR SERIOUS INJURY CAN OCCUR
• Always adjust restraint harness for a comfortable and
snug t around child. A snug harness strap should not
allow any slack. It lies in a relatively straight line without
sagging. It does not press on the child’s esh or push
the child’s body into an unnatural position.
• This restraint is not for use in homes, boats, on a motor-
cycle or in any other non-specied applications or
environments.
• Always keep this child restraint secured in the vehicle
even when it is unoccupied, using the lower universal
anchorage system (UAS) or vehicle seat belt, and also the
tether strap.
• Do not carry restraint by harness adjusting strap. This
can damage the mechanism and the webbing. Only
carry restraint by red carry strap, harness shoulder straps
or by the plastic shell.
• In the event of an accident, the vehicle body itself
provides the most signicant passenger protection.
While a properly installed restraint will improve chances
for survival in most accidents, some crashes are unsur-
vivable regardless of what restraint is used.
• Based on accident statistics, Diono recommends the
vehicle’s rear seat as the safest location for all children
under age 13.
• Register this restraint with the manufacturer using the
attached registration card.
Seating Position Information
WARNING:
• Use restraint ONLY with forward-facing vehicle seats.
• DO NOT use restraint with side-facing or rear-facing
vehicle seats in vans, trucks or station wagons.

Child Restraint Safety Information
• This restraint meets all applicable Canada Motor
Vehicle Safety Standards.
• This restraint is certied for use in motor vehicles and
aircraft.
• Register this restraint with the manufacturer.
Child restraints can be recalled for various reasons. To be
reached directly in the event of a recall, you must register
your restraint with the manufacturer. Fill out the included
product registration card and mail it. You can register
online at www.diono.com. You can also register by
sending your name, address, the restraint’s model and
serial number to:
Diono Product Registration
275 Frobisher Dr., Suite 3
Waterloo, ON N2V 2G4
Or you can call Diono: 519-725-1700.
WARNING: DO NOT place a child
restraint in the front seat of a
vehicle with a passenger air bag
unless the air bag is turned o.
DEATH or SERIOUS INJURY can
occur. The back seat is the safest.
IMPORTANT:
• Before each use, always conrm restraint is securely
installed and harness is properly adjusted around the child.
Remember: The addition or removal of clothing (such as a
sweater or coat) will change the t of the harness.
• Always conrm before each use that restraint is securely
locked in its unfolded position.
• Make sure vehicle seats which fold forward are securely
locked in their open position. An unsecured vehicle seat
back can impair the ability of the restraint to protect the
child occupants.
• Cover restraint when vehicle is parked in direct sunlight.
Parts of the restraint can become hot and cause injury to a
child.

7
• Do not leave any child in a vehicle alone or unattended by
an adult.
• Secure all personal objects inside the vehicle. In an ac-
cident loose object can become ying hazards with the
potential for causing serious injury.
• Except per the instructions in this manual, do not disas-
semble, attempt to disassemble or tamper with any part of
this restraint or change the way the restraint harness or the
vehicle restraint system is used.
• Do not use restraint if there is any appearance of rust on
any of the metal surfaces.
• Do not oil or lubricate any part of the restraint.
• Release levers and locking bolts should operate smoothly
and freely. When release levers are lifted, the release levers
and locking bolts should spring back immediately and
completely. Do not use restraint if release levers and/or
locking bolts wither bind or do not move freely.
• When not in use, store restraint properly and avoid placing
heavy objects on top of it.
To prevent injury to child:
•Do not use restraint in harness mode if it is older than
eight years. Do not use this restraint in booster mode
if it is older than 10 years. Manufacture date is on side
of restraint.
•Do not use restraint after is has been involved in any
accident. Damage to the restraint may have occurred
which could impair its ability to adequately protect a
child.
• This restraint is not a toy. Do not allow children to play
with it.
• Using any non-Diono product with this restraint, or any
product not specically approved by Diono for use with this
restraint, is not allowed. Use of such products voids manu-
facturer’s warranty and may seriously impact this product’s
ability to perform properly in an accident.
• Fill out Emergency Child Information form in front ap of
restraint.

Seat Belt Information
The information below applies only to installations using
vehicle seat belts.
IMPORTANT:
• This restraint can be installed securely in most vehicles
using the seat belt. However, some seat belts have an
anchoring position for the lap belt that may not allow a
secure restraint installation.
• Some vehicles do not have any seating positions that
are compatible with a child restraint. Read owner’s
manual to determine child-specic seating. Contact
the vehicle manufacturer if you have any doubts or
questions.
Some vehicle seat belts that are NOT compatible with this
restraint are:
• Seat belts with top or bottom anchorage points
attached to the front door.
• Motor driven automatic seat belts.
• Non-locking, (ELR) two-point vehicle seat belts.
If your seat belt is of a type listed above, choose another
seat within the vehicle or use LATCH connectors and
anchorage points. Information on the types of seat belts in
your vehicle are in the vehicle owner’s manual.
