Thank you for purchasing the CYBEX ATON G. We are proud to bring this German-
engineered product to the United States and Canada. We hope the ATON G will make your
child’s travel both safer and more pleasant, as well as make installation and use for you as
simple as possible.
Statistics show that over 75% of Child Restraints are being used incorrectly!
Please read and follow these instructions carefully to install the CYBEX ATON G correctly,
even if the installation and use of this Infant Car Seat might seem simple and intuitive.
Before the rst use of the CYBEX ATON G Infant Car Seat, please make sure you have
followed all the steps in the Safety Checklist on pg. 72.
Following the American Academy of Pediatrics' recommendations for safe transportation
of infants, we recommend children remain in a REAR-FACING car seat as long as
possible, until they reach the highest weight or height allowed by their seat. Visit
www.aap.org for more information on the Academy's recommendation.
No car seat can guarantee protection from injury in every situation, but proper use helps
reduce the risk of death or serious injury. If you have any questions or need assistance,
please contact ParentLink Customer Service at 1-877-242-5676 (USA and Canada).
Also, please remember to register your Infant Car Seat so we can contact you in the

According to the U.S. National Highway Trafc Safety Administration (NHTSA), car
seats and boosters provide protection for infants and children in a crash, yet car
crashes are a leading cause of death for children.
To reduce the risk of SERIOUS INJURY or DEATH, read this owner’s manual and your
vehicle owner’s manual before installing and using this Car Seat. Using a Car Seat
makes a big difference. By properly using this Car Seat and following these instructions,
the instructions on the Car Seat, and the instructions that accompany your vehicle, you
will greatly reduce the risk of serious injury or death to your child from a crash. Do not
be misled by the commonly used term “safety seat”; no restraint system can prevent all
injuries in all crashes. Many properly restrained adults and children are injured in motor
vehicle crashes, including relatively minor crashes. A properly used Car Seat is the best
way to minimize injuries to your child and to increase the chances for your child’s survival
in most crashes.

This Child Restraint is designed for use by children in REAR-FACING MODE ONLY. To
use this Child Restraint properly, children MUST meet the size and age requirements on
the following pages.
The American Academy of Pediatrics (AAP) recommends keeping children REAR-FACING
for as long as possible, until they reach the maximum height or weight for their Child

Minimum 2.5 cm
(1 in)
Child Usage Guidelines
Do not use this Child Restraint if your child does not meet
all of these requirements:
• Weight is between 1.8 and 15.8 kg (4 and 35 lbs)
• Height is between 43 and 81 cm (17 and 32 in)
• Top of child's head is a minimum of 2.5 cm (1 in) below the
top of the Infant Car Seat or Headrest, WHICHEVER IS
HIGHER.
IMPORTANT: Once your child EXCEEDS any of the size
requirements above, they MUST DISCONTINUE use of this
Child Restraint. After your child outgrows the ATON G, keep
your child REAR-FACING in a convertible or all-in-one car seat
as long as the seat allows, according to the manufacturer's
specications, before turning them around to ride FORWARD-
FACING.
IMPORTANT: For proper use of the Infant Car Seat, the
Harness Straps MUST be AT OR JUST BELOW your child's
shoulders.
NOTE: Regularly check for proper Harness height as your child
grows.

10
Before using this Child Restraint for preterm or low birth weight infants, ensure the
Child Requirements are met and follow the guidelines in this section.
According to the National Highway Trafc Safety Administration (NHTSA), a properly
installed Child Restraint reduces the risk of death by over 70% for infants involved in
crashes. Federal Motor Vehicle Safety Standard (FMVSS) 213 establishes design and
dynamic performance requirements for Child Restraint systems. However, the standard
has no minimum weight limit and does not address the special medical needs of preterm
or low birth weight infants. To ensure that preterm and low birth weight infants are
transported safely, the guidelines published by the American Academy of Pediatrics (AAP)
in Pediatrics 2009;123:1424–1429 (reafrmed June 2018) must be followed.
Preterm and low birth weight infants are at additional risk of breathing difculties and
heart problems when placed in a Child Restraint. CYBEX requires that the evaluation
recommended by the AAP be conducted for all infants born earlier than 37 weeks and all
newborn infants who weigh less than 2.26 kg (5 lbs) at birth before their rst car trip to
check for breathing difculties or heart rate problems when traveling in a REAR-FACING
Child Restraint. Newborn infants should NEVER travel in a FORWARD-FACING Child
Restraint.
The AAP recommends that appropriate hospital staff observe your infant in the Child
Restraint for a period of 90 to 120 minutes or the duration of travel, whichever is longer.
This period of observation must be performed with the infant properly positioned as
described in these instructions and with the Child Restraint placed at an angle that is
approved for use in the vehicle. The hospital staff will check for any breathing difculties
or heart rate problems. Your child’s pediatrician will let you know if there are any special
Child Usage Guidelines
Premature Infant Use

11
considerations for travel. The number of trips and the duration of time the infant is seated
in the Child Restraint should be minimized. A caregiver should ride in the back seat to
monitor the infant during travel.
You can learn more about the AAP’s recommendations as well as other resources for
parents and medical professionals, at https://www.healthychildren.org/english/safety-
prevention/on-the-go/Pages/default.aspx.
Child Usage Guidelines
Premature Infant Use
Routing the Harness Buckle for Use with
Premature and Smaller Infants
1. Partially remove the Seat Cover from the
front of the seat.
2. From the top of the seat, feed the Buckle
Anchor and Harness Buckle Cover
through the rear slot in the Seat Cover.
3. Feed the Buckle Anchor through the
rear slot and then from underneath the
seat, feed the Buckle Anchor up through
the middle slot, making sure it goes
completely through the slot and lays at
against the bottom of the seat.
4. Replace the Seat Cover.
5. See pages 60 - 61 for more information.

Restraint will substantially improve the
chances for survival in most crashes.
• READ this Owner’s Manual carefully
before rst use and keep it for future
reference.
