REGISTER THIS CAR SEAT OUR STORY
Time. It goes so fast... Who would have thought that over
two decades have passed since we first stepped out into the
world and started a business dedicated to family travel.
Well the world has changed a lot, but we’re proud to say
that we haven’t, (sure we’ve grown up), but we’re still as
passionate about what we do today as we were back then.
Our story is ‘made of Seattle’, a city like no other. This is a
place where creative minds & innovators rub shoulders within a
landscape of adventure; a place, where being ‘a little dierent’, is
the everyday norm.
With a love for design and an understanding of modern
parenting, we strive to create amazing products, so that you
and your little ones can celebrate the joy in every journey.
People who own Diono products can be found in all four
corners of the big blue green ball, we all call home. Some are
fans & followers, some are supporters, tweeters, social media
magicians, miracle moms and devoted dads.
Without your passion, pictures, words and stories, we would
never hear your voice. So tell us about your patch of grass,
and join in the hustle and bustle at diono.com.

• Transport Canada designates that you MUST
replace this child restraint if it has been involved
in a collision, even if you cannot see visible
damage. A damaged child restraint may not
protect your child in a future collision.
UNITED STATES
The U.S. National Highway Trac Safety Administration
(NHTSA) recommends that car seats be replaced
following a MODERATE or SEVERE collision in order
to ensure a continued high level of collision protection
for child passengers.
Car seats do not automatically need to be replaced
following a MINOR collision. NHTSA defines a MINOR
collision as ALL of the following:
• The vehicle was able to be driven away from the
collision site; AND
• The vehicle door nearest the car seat was not
damaged; AND
• No vehicle occupants were injured; AND
• There is no visible damage to the car seat; AND
• The airbags (if present) did not deploy.
NEVER use a car seat that has been involved in a

The safest seating position is one that works best for
your specific child restraint, family and vehicle model.
Before installing this child restraint you must determine
the method of installation and the best vehicle seating
position for that method. This child restraint can be
installed either using LATCH/UAS or the Vehicle Seat Belt.
DO NOT install using both methods at the same time.
When determining whether the child restraint can
be used with vehicle LATCH/UAS anchors in the rear
center seating position, it is critical that you refer to
your vehicle owner’s instruction book. If the child
restraint does not install best in the rear center seating
location, it is recommended to move
to one of the outboard
seating positions.

VEHICLE SEATING LOCATIONS LATCH/UAS
WHAT IS LATCH/UAS?
Most vehicles manufactured after
September 1, 2002 are equipped
with:
U.S.: LATCH (Lower Anchors and
Tethers for CHildren)
Canada: UAS (Universal Anchorage System)
Check your vehicle owner’s instruction manual to
determine LATCH/UAS lower anchor compatible
seating positions. Some vehicles owner’s manuals use
the term “ISOFIX” instead; LATCH/UAS can also be
used in vehicle seating positions that are equipped with
ISOFIX. Look for the LATCH/UAS symbol that may be
visible by the crease of the rear seats.
WARNING: DO NOT USE the LATCH/UAS strap to
attach this child restraint rear-facing when restraining
a child weighing over 35 lb (15.8 kg) or forward-facing
when restraining a child weighing over 40 lb (18 kg).
Install using the vehicle seat belt.
DO NOT install using both LATCH/UAS connectors
and the vehicle seat belt at the same time.
