Welcome to the CYBEX family.
Thank you for purchasing the CYBEX ETERNIS S. We are proud to bring this German-engineered
product to the United States. We hope the ETERNIS S will make your child’s travel both safer and
more pleasant, as well as make installation and use for you as simple as possible.
The ETERNIS S brings a few important safety innovations to the All-In-One car seat category.
CYBEX Linear Side-Impact Protection (L.S.P.) System
The L.S.P. System allows the forces from a side impact collision to be reduced gradually to
minimize injuries. An adjustable head rest, deep side wings lined with thick energy absorbing EPS
foam, and an adjustable device create the CYBEX L.S.P. system. This system has been
optimized to protect and reduce forces on your child in the event of side impact crashes.
Statistics show that over 75% of car seats are being used incorrectly!
Please read and follow these instructions carefully to install the ETERNIS S correctly, even if the
installation and use of this Child Restraint might seem simple and intuitive.
WELCOME TO CYBEX!

Before the first use of the ETERNIS S Child Restraint, please make sure you have followed all the
steps in the Safety Checklist on page 112.
Following the American Academy of Pediatrics' recommendations for safe transportation of infants,
we recommend children remain in a REARFACING car safety 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
CYBEX at 1-877-242-5676. Also, please remember to register your Child Restraint so we can con-
tact you in the unlikely event of a recall. Keep this Owner’s Manual for future reference by storing
it in the compartment on the back of the ETERNIS S Child Restraint. We appreciate your purchase
and invite you to visit www.cybex-online.com/us to see other great CYBEX products.

GENERAL WARNINGS
•NEVER USECHILD RESTRAINT IF IT HAS
DAMAGED, BROKEN OR MISSING PARTS.
•ALWAYS REPLACE THE CHILD RESTRAINT
AFTER A CRASH OF ANY KIND EVEN IF
IT WAS UNOCCUPIED. A crash can cause
unseen damage to the child restraint that
may not be visible.
•NEVER install or use this child restraint
until you have read and understand the
instructions in this manual, the labels on
your child restraint and in your vehicle
Owner’s Manual. If there is a conflict
between the two, the vehicle Owner’s
Manual must be followed. Failure to follow
these instructions can result in death or
serious injury to your child in a crash.
•NEVER allow someone else to use this child
restraint without also passing along this
manual to them.
WARNING! DEATH or SERIOUS INJURY can occur.
!
•The primary protection for occupants of a
vehicle in a collision is the structure of the
vehicle itself. Correctly used, this child restraint
will substantially improve the chances for
survival in most crashes.
•ALWAYS check buckles and other parts for hot
surfaces before placing your child in the child
restraint. A hot surface could burn your child!
Cover an unoccupied child restraint with a
blanket when leaving it in a vehicle exposed to
sunlight.
•NEVER leave an empty child restraint
unsecured in your vehicle. This restraint must
always be secured, even when not occupied.
An unsecured child restraint could injure vehicle
occupants in a sudden stop or crash.
•DO NOT attempt to make repairs to or
otherwise modify or tamper with this child
restraint.

12
WARNING! DEATH or SERIOUS INJURY can occur.
!
LOCATION WARNINGS
•ACCORDING TO ACCIDENT STATISTICS, children are safer when properly restrained in rear vehicle
seating positions, rather than in the front seating positions.
•ONLY place this child restraint in a vehicle seating location allowed by the vehicle manufacturer.
Refer to your vehicle‘s Owner’s Manual for information about vehicle seat belt systems, air bags,
side air bags, front passenger side air bags and child restraint installations, to determine allowable
seating positions.
•Not every location within a vehicle may be safe for the installation of this child restraint. In fact,
some vehicles have no seating position that is safe for the installation of this child restraint. Improper
placement of this child restraint within a vehicle will increase the risk of death or serious injury.
•NEVER use this child restraint in a vehicle seating position where it cannot be secured tightly. A
loosely installed child restraint will not protect your child in a crash.
•NEVER LEAVE a vehicle seat back with a folding mechanism unlocked. In the event of a sudden
stop, an unlocked vehicle seat back could prevent this child restraint from protecting your child.
•NEVER use this child restraint with any motorized, or door mounted vehicle seat belts. Your child
restraint would not be properly restrained in the event of a crash.
•NEVER use this child restraint on boats, low speed vehicles (LSV), all-terrain vehicles (ATV), golf
carts, or any other non-certified application.
•ONLY use this child restraint on vehicle seats with backs that lock into place.
•This child restraint is allowed to touch the vehicle seat in front of it as long as the recline angle of the
child restraint is not aected.

13
LOCATION WARNINGS
•NEVER LEAVE CHILD UNATTENDED in or around the vehicle even for one minute. Vehicle
backovers can happen in any type of vehicle. Vehicles have blind spots, the areas around the
vehicle that you can not see from the driving position. Always check around the vehicle before
moving your vehicle.
•ALWAYS use a Linear Side-impact Protection (L.S.P.) (see page 40-41) device on the side of the
child restraint immediately adjacent to a vehicle door or panel.
•NEVER extend a Linear Side-impact Protection (L.S.P.) device toward a passenger or another
child restraint.
•ONLY use this child restraint on FORWARDFACING vehicle seat. NEVER install this child
restraint in vehicle seats that face the rear or side of the vehicle.
WARNING! DEATH or SERIOUS INJURY can occur.
!
•VEHICLE TYPES WHICH THE RESTRAINT SYSTEM CAN NOT BE USED:
- This child restraint is not to be used in vehicles that do not have vehicle seat belts or lower
anchorages (LATCH).
•DO NOT USE this child restraint with inflatable seat belts.

14
REAR-FACING WARNINGS
•When using this restraint REARFACING, DO NOT loosen the vehicle seat belt to provide more
leg room, as this may keep the child restraint from protecting the child.
•Fold-down armrests could pose a hazard to a REARFACING child in certain types of collisions.
Consult your vehicle owner’s manual before installing any REARFACING child restraint in front
of a fold-down armrest.
•NEVER turn a child restraint FORWARDFACING with a child who weighs less than 22 lbs (10 kg).
Crash forces may cause serious injury or death.
•DO NOT use the tether strap when the child restraint is in the REARFACING position.
•The headrest on the vehicle seat that the child faces when sitting in the REARFACING mode
should be placed in the lowest position. The vehicle seat back that the child faces must be fully
padded and free of any hard objects.
•IMPORTANT: Infants may have diculty breathing when in an upright seated position. Make sure
they recline enough for their head to lie back comfortably and safely. Failure to properly recline
the child restraint could increase the child’s risk of serious injury or death.
•DO NOT USE this child restraint if the top of your child‘s head is less than 1 inch (2.5 cm) from the
top of the headrest when used REARFACING.
•SOME CHILDREN WITH SPECIAL NEEDS, such as preemies or those who have tested positive
for positional apnea, may be at increased risk of suering breathing or other diculties in a child
restraint. Please consult a physician to determine what type of child restraint should be used.
WARNING! DEATH or SERIOUS INJURY can occur.

15
CHILD FIT WARNINGS
•ALWAYS check the harness buckle to make sure it is securely latched.
•SNUGLY ADJUST the belts provided with this child restraint around your child.
•NEVER use bulky clothing or blankets that will interfere with properly positioning or tightening
the harness.
•ALWAYS keep your child properly secured in the harness. 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 flesh or
push the child’s body into an unnatural position.
FORWARD-FACING WARNINGS
•If your child weighs more than 65 lbs (29.4 kg) or their shoulders are above the highest harness
level, you MUST use child restraint in booster mode.
•Adjust, or remove, the vehicle headrest in the seat where the child restraint is to be installed, so
that the back of the child restraint rests against the vehicle seat back.
•The headrest on the vehicle seat in front of the child should be put in its lowest position. The
vehicle seat back that the child faces must be fully padded and free of any hard objects.
WARNING! DEATH or SERIOUS INJURY can occur.
!

16
BOOSTER MODE WARNINGS
•DO NOT use this booster seat REARFACING.
•WARNING! Use ONLY the vehicle’s lap AND shoulder belt system when restraining the child in
this booster seat.
•NEVER use a lap belt only.
•The shoulder belt MUST be threaded
through the shoulder belt guide.
•DO NOT use this booster seat if the
tops of the child’s ears are above the
back of the booster seat headrest.
•The shoulder belt MUST NOT cross
the child’s neck or fall o the child’s
shoulder. If you cannot adjust the
shoulder belt to properly lie midway between the child’s shoulder and neck AND at or just above
the shoulder, try another seating location or do not use the booster seat.
WARNING! DEATH or SERIOUS INJURY can occur.

ADDITIONAL WARNINGS
•If the lower anchor connectors are not being used make sure they are securely stored.
•NEVER use this child restraint when it is older than ten (10) years. The date of manufacture can be
found on a label axed to the bottom the child restraint.
•NEVER use this child restraint if any of the Harness or LATCH straps are cut, frayed, or damaged in
any way.
•NEVER use accessories or parts with this child restraint other than those approved by CYBEX. Use
of accessories or parts from other manufacturers could alter the performance of the child restraint.
•REGISTER your child restraint with the manufacturer. This is the best way to reach you in the event
of a recall.
•DO NOT allow children to play with this child restraint.
•DO NOT allow children to play with vehicle seat belts. They may create an entanglement hazard
for any child that can reach the seat belt and may wrap it around his or her neck.
•DO NOT leave loose objects (e.g. groceries, books, bags) in a vehicle. In the event of a sudden
stop, loose objects will keep moving, potentially causing serious injuries.
•NEVER tend to your child’s needs while driving. ALWAYS safely stop your vehicle in order to tend
to your child.
•NEVER take your child out of the child restraint while the vehicle is moving. Unrestrained
occupants are at a greatly increased risk of death or serious injury in a car crash.
•DO NOT place any cups that contain hot liquids in the cup holder.

18
SEAT BELT WARNINGS
•ALWAYS read your vehicle owner's manual to determine what
vehicle belts and retractors are used in your vehicle belt. If not
able to secure a tight installation, the vehicle belt MUST lock and
MUST NOT loosen after the seat belt is tightened.
•DO NOT use this child restraint if it moves more than 1 in. (2.5
cm) side to side or front to back at either the REARFACING or
FORWARDFACING belt path on the child restraint. Serious injury
or death may result from poor installation. If you cannot tightly
secure the child restraint, try again or move it to another location.
Retractor
•DO NOT use this child
restraint in a vehicle
with seat belts that
automatically move
along the vehicle
frame when the
door is opened.
•DO NOT use this child
restraint in a seating
position with
door-mounted seat
belts.
WARNING! DEATH or SERIOUS INJURY can occur.
!

19
•DO NOT use this child restraint in a vehicle equipped
with lap belts that only lock during a sudden stop or
crash (emergency locking retractor – ELR). You must use
a seating location with a locking seat belt. Check your
vehicle owner’s manual to see if you have lap belts with
ELRs.
SEAT BELT WARNINGS
•DO NOT use on vehicle seats when both portions of the
vehicle belts are positioned forward of the seat crease.
WARNING! DEATH or SERIOUS INJURY can occur.
!

20
•DO NOT use with lap/shoulder belts with two retractors. If the vehicle
seat belts are not routed and fastened correctly, the child restraint may
not protect the child in a crash.
•DO NOT use with inflatable seat belts.
•Check your vehicle owner’s manual to determine how to lock your
seat belt for child restraint installation.
•DO NOT allow the vehicle seat belt release button to touch the child restraint. Accidental contact
may cause the seat belt to release. If necessary, turn the seat belt release button away from the
child restraint or move the child restraint to a dierent location.
•Failure to adjust the harness or vehicle seat belts snugly around the child may result in the child
striking the vehicle’s interior during a sudden stop or crash. Serious injury or death may occur.
•Child restraint systems should be securely belted to the vehicle, even when it is not occupied,
since in a crash an unsecured child restraint system may injure other occupants.
