!WARNING! !DEATH OR SERIOUS INJURY CAN OCCUR!
!
!
Never place this child restraint rear-
facing in a vehicle seating location with
an active front air bag. Death or serious
injury may occur. If an air bag inates,
it can hit the child or child restraint with
enough force to cause serious injury or
death to your child. For vehicles with side
passenger air bags, refer to your vehicle
owner’s manual for information on your
child restraint installation.
Take care to secure the child properly. Snugly adjust the
harness straps provided with this child restraint around
your child. A snug strap should not allow any slack. It lies
in a relatively straight line without sagging. It does not
press on the child’s skin or push the child’s body into an
unnatural position.
For any questions or concerns please contact diono at:
Diono U.S.:
1-855-463-4666 or online at www.diono.com

EXPIRATION
• DO NOT use the child restraint if any part is damaged
or broken, expired ten year of date of purchase (8
years in 5-point harness, 2 years in booster), missing
instructions, missing parts, or if the straps are cut,
frayed, or damaged in any way. Call to nd out if the
damaged part or parts can be replaced.
Diono U.S.: 1-855-463-4666
SAFE PRACTICES
• DO NOT leave loose objects, such as books, bags,
etc., in the back of the vehicle. In the event of a sharp
turn, sudden stop, or collision, loose objects can be
thrown around and possibly cause serious injury to
vehicle occupants.

your child. In warm weather, child restraints can
become very hot. Do not allow children to play with
vehicle seat belts.

!WARNING! !DEATH OR SERIOUS INJURY CAN OCCUR!
!
!
• DO NOT use any accessories, inserts or products not
included with this child restraint, unless approved by
Diono. Items not tested with this child restraint could
injure your child.
• NEVER remove harness from child restraint without
following the proper removal and installation
instructions.
• DO NOT use child restraint without seat cover installed.
• ALWAYS check seat belt or LATCH connectors to ensure

diono.com 15
!DEATH OR SERIOUS INJURY CAN OCCUR! !
!
• DO NOT use child restraint in any conguration not
shown in the instructions.
• DO NOT modify your child restraint.
• NEVER install in a seat that is rear-facing, side-facing or
on the back of a folded down vehicle seat.
• ALWAYS secure this child restraint with the vehicle’s
child restraint anchorage system (LATCH) if available OR
the vehicle seat belt.
• NEVER use the restraint system in a vehicle seating
position where it cannot be secured tightly. A loosely
installed restraint system will not protect your child
in a collision.

rear-facing when restraining a child weighing more than
35 lb (15.8 kg) or forward-facing when restraining a child
weighing more than 40 lb (18 kg).

CAR SEAT USE AFTER A 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. In the U.S., car seats
do not automatically need to be replaced following a
MINOR collision.
NHTSA defines a MINOR crash as one in which ALL of
the following apply:
• The vehicle was able to be driven away from the
crash site.
• The vehicle door nearest the car seat was not
damaged.
• None of the passengers in the vehicle sustained any
injuries in the crash.
• If the vehicle has air bags, the air bags did not
deploy during the crash; and
• There is no visible damage to the car seat.
NEVER use a car seat that has been involved in a
MODERATE or SEVERE collision.
