General Warnings
Child Restraint Use
When used with built-in harness, use
ONLY with children who weigh 5–65 lb
(2.3–29.4 kg) and whose height is 49
inches (124 cm) or less.
When used without built-in harness as a
belt positioning booster, use ONLY with
children who weigh between 40–120 lb
(18–54 kg) and whose height is 38 to 57
inches (96 to 145 cm).
DO NOT use in any configuration not
shown in the instructions. Please refer to
vehicle owner’s manual for recommended
or suggested installation positions.
DO NOT use the child restraint if it is more
than 10 years old. Check the label or
stamped “do not use after” date on the
bottom of the child restraint.
DO NOT use another manufacturer’s
cover, padding, fabric, or other soft
materials with this child restraint, as these
constitute an integral part of the child
restraint performance.
DO NOT modify your child restraint or use
any accessories or parts supplied by other
manufacturers unless they are approved
by Nuna for use with this child restraint.
Doing so may be unsafe and may void the
warranty.
DO NOT use a cut, frayed or damaged
vehicle seat belt. NEVER use the child
restraint if it has frayed or cut harness
straps, any damaged or missing parts,
or has been in a damaging crash. To find
out if damaged parts are replaceable, call
1-855-NUNA-USA.
NEVER use a car seat that has been
involved in a moderate to severe crash.
See page 18 to learn the difference
between a minor and moderate to severe
crash.
Child Restraint Safety
DO NOT allow anyone who has not read
the instructions to install or use this child
restraint. NEVER give this child restraint to
another person without also giving them
these instructions.
NEVER leave child unattended in this child
restraint.
WARNING
DEATH OR SERIOUS INJURY CAN OCCUR,
8EXEC™instructions 9EXEC™instructions

To avoid strangulation, do not allow
children to play with vehicle or child
restraint belts or straps. If possible, move
unused belts out of reach.
Cover the child restraint when your vehicle
is parked in sunlight. Parts of a child
restraint can become very hot if left in the
sun, and can burn a child’s skin. Check for
hot parts before putting your child in the
child restraint.
NEVER leave child restraint unsecured in
your vehicle even when it is unoccupied. In
a crash, it could become a projectile and
injure other vehicle occupants.
NEVER leave luggage or other objects
unsecured in a vehicle, as they are liable to
cause injuries in the event of a collision.
Additional Booster Warnings
Booster Installation
DO NOT install on a rear facing or side
facing vehicle seat.
This booster should be installed in the rear
vehicle seat so that it can be installed with
the vehicle lower anchors.
DO NOT install in the front passenger seat
with an active airbag, unless the air bag
can be turned OFF.
The child restraint is NOT certified for
aircraft use when used as a booster.
Aircraft belts are lap belts only, and a child
cannot be secured in the booster with only
a lap belt.
Vehicle Belt Positioning
WARNING! Use ONLY the vehicle’s lap
and shoulder belt system when restraining
the child in this booster seat. Use of any
other method of securement will not
properly secure the child, which could
result in serious injury or death. DO NOT
use the built-in harness when using the
booster seat.
Properly position the vehicle lap and
shoulder belt on your child. Make sure the
vehicle lap and shoulder belt are not loose.
A loose or improperly positioned vehicle
lap and shoulder belt could cause the child
to be ejected in a sudden stop, turn or
crash and cause serious injury or death.
The vehicle shoulder belt should rest on
the child’s shoulder and across the center
of the chest.
The vehicle lap belt must remain snug
across the child’s thighs.

Using LATCH
LATCH (Lower Anchors and Tether for CHildren) is
a system for installing a child restraint in a vehicle
without using the vehicle belts. This child restraint
can be installed without vehicle belts by connecting
the child restraint’s lower anchor belt to the lower
anchorages in your vehicle.
Refer to your vehicle owner’s manual to determine
if your vehicle is equipped with LATCH, and how to
correctly use LATCH to install this child restraint in
your vehicle.
LATCH use is based on mode, as specified below:
Lower anchors only
Lower anchors and tether
LATCH Location
Common locations of LATCH in a vehicle are shown
below (consult your vehicle owner’s manual). Other
locations of the tether are shown on the next page.
Vehicle Compatibility
This child restraint can ONLY be installed on
vehicle seats that face forward. DO NOT install in
seats that face to the sides or rear of the vehicle.
IMPORTANT: According to accident statistics,
children are safer when properly restrained in the
rear seating positions than in the front seating
positions.
WARNING: You MUST read and understand
ALL child restraint related instructions and
warnings in your vehicle owner’s manual to
correctly and safely use this child restraint in
your vehicle.

LATCH without Built-in Harness (Booster)
Non-standard spacing of the lower anchors is
allowed in booster mode ONLY IF the vehicle
manufacturer allows it; consult your vehicle
owner’s manual.
An example of non-standard spacing is installing
the booster in the center seating position of your
vehicle where there are no lower anchors and
using the closest lower anchors from the outboard
positions instead.
When using non-standard spacing, lower anchors
MUST NOT interfere with the vehicle seat belt.
DO NOT use tether in booster mode.
Using Vehicle Belts
Vehicle belt type is based on mode, as specified
below:
Lap/Shoulder Belt (A)
Lap Belt Only (B)
Belts MUST be able to be locked. Refer to your
vehicle owner’s manual to determine if the belts
in your vehicle lock by: A) switching the seat belt’s
retractor by pulling the belt all the way out, or
B) a locking latch plate that locks the vehicle’s seat
belts so they will not move freely.
If the belt cannot be locked using one of these
methods, contact Nuna Customer Service for a
locking clip.
LATCH with Built-in Harness
When installed rear facing or forward facing, this
child restraint is designed to be used with lower
LATCH anchors at the standard spacing of 11 inches
(28 cm). LATCH lower vehicle anchor points are
defined as 11 inches (28 cm) from the center of
one LATCH anchor to the center of another LATCH
anchor.
WARNING: DO NOT USE the LATCH lower
anchor belt to attach this child restraint
rear facing when restraining a child weighing
over 35 lb (15.8 kg) or forward facing with built-
in harness when restraining a child weighing
over 40 lb (18.1 kg). Check your vehicle owner’s
manual for tether anchor weight limits (use
tether forward facing ONLY).
Tether
The child restraint’s tether strap should be used
for ALL forward facing installations (except booster
mode) as it provides a more secure installation and
is proven to be safer. In a crash, the tether limits a
child’s forward movement, protecting their head and
neck and reducing the risk of injury.

Car Seat Use after a Crash
The National Highway Traffic Safety Administration
(NHTSA) recommends that car seats be replaced
following a moderate or severe crash. Car seats
do not automatically need to be replaced following
a minor crash.
A minor crash is one in which ALL of these apply:
• The vehicle was able to be driven away from
the crash site.
• The vehicle door nearest to 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, none of the air bags
deployed during the crash; and
• There is no visible damage to the car seat.
Any crash that does not meet all of the above
criteria for a minor crash is considered a moderate
to severe crash. NEVER use a car seat that has
been involved in a moderate to severe crash.
Information from nhtsa.gov
Aircraft Installation
Install child restraint rear or forward facing in a
forward facing aircraft seat following Vehicle Lap Belt
instructions (p.48 or p.56), but install aircraft belt on

Leg Rest Use
The fully adjustable leg rest can be used in all three
modes of the child restraint, and it serves as both
a safety and a comfort feature. The leg rest can be
angled to achieve proper leg support and extended
for longer legs.
Rear Facing
In this mode, the leg rest not only provides increased
leg room, but also serves as an anti-rebound panel,
which aids in achieving proper installation tightness.
1 -In rear facing mode, the leg rest MUST be
in the upright position. The angle of the leg rest
should match the angle of the vehicle seat back.
Forward Facing or as a Booster
In these modes, the leg rest provides leg support
and protects your vehicle seat from dirty shoes.
To Adjust Leg Rest:
2 - Push and hold the buttons on both sides of the
leg rest. You can now angle and extend the leg
rest simultaneously.
3 - Adjust the leg rest to the desired position by
tilting to rotate the angle (1) and pulling forward
to extend for a child with longer legs (2).
Once you reach the desired position, release the
buttons. You will hear them click as they spring
back into place, locking the leg rest.
If the buttons do not spring back right away, gently
tilt the leg rest until it locks into place. Angle must
be locked before extension can be locked.
