muscular dystrophy, hypotension) can be supported in their posture by means of
individually positioned thorax pads and special upholstery which ensures a safe
transportation.
Important optional accessories can be used to address specific needs such as: the
seat angle or the installation of a stable abduction wedge or a footstool. More in

1. A standard child car seat from Römer-Britax (please refer to the manufacturer's
manual for use).
2. Adaptation module with accessories, which offers the possibility to equip the car
seat according to individual needs. Please observe the instructions for use from
HERNIK GmbH.

HERNIK GmbH declares in sole responsibility that car seat "STARLIGHT-NXT"
complies with the Essential Requirements (Appendix 1 of Directive 93/42 EEC). The
product is marked with the CE mark according to the above mentioned directive.
1.5 Warranty
A warranty can only be accepted if the product is used under the specified
conditions and for the intended purposes. The manufacturer is not liable for
damage caused by components and spare parts which were not approved by the
manufacturer.
1.6 Service and repair
Service and repairs on the STARLIGHT-NXT may only be carried out by specialized
dealers. If you have any problems, contact your local dealer. For repairs, you will
only receive original spare parts.
1.7 Practical instructions
The car seat will be delivered fully assembled. Upon delivery, the dealer will instruct
the user how to use the device by using the manual. The specialist dealer should

II. Safety instructions
· Before use, the components must be checked for perfect function and
condition.
· The instructions for use must always be carried on the child car seat.
· The safety of your child is only guaranteed if the seat is installed correctly and
if the child is fixed exactly.
· The straps must be laid tight and without twisting.
· The 3-point safety belt is to be guided through the provided belt guides and
is supposed to surround the seat tightly.
Please check:
A) whether the seat belt is securely placed in the belt guide
B) whether the belt buckles are locked correctly
C) that no textiles are impacted
· Make sure that no solid objects like pins, belt buckles, etc. are placed between
child and seat belt. This could lead to injuries in the event of accidents.
· Explain to your child how important it is to be well-secured and that the
course of the straps do not change. It shouldn't pull on the straps nor
open the belt buckles.
· Do not make any changes to the car seat, otherwise you risk your child's
safety.
· The car seat must not be damaged by moving parts in the car or through
doors.
· Never leave your child alone in the child car seat.
· Inform your passengers how your child can be taken out of the seat after an
accident.
· After an accident, the entire child car seat has to be renewed.

• Pull the locking bracket lightly on the 
backrest of the seat until it releases from the
toothing. Move it together with the headrest
 to the desired position. Finally, release the
bracket so that it can engage again - see Fig.
1.
ATTENTION: If the locking bar is already at
the highest point and you still need more back
or headrest height, the XL kit should be
retrofitted or a larger car seat be selected!
• Now the two-piece back cushion has to be
adjusted. Loosen the scratches between the
front back cushion and the wedge-shaped 
balance pad , which is behind it - see Fig. 2.
• Align the back cushions , make sure that the 
connected head restraints are seated correctly,
and revert the underside of the cushion
around the wedge-shaped cushions .
Make sure that no wrinkles form and a smooth
crossover is created.

IV. Installation of the XL-Kit
• The XL-Kit allows you to use the STARLIGHT-
NXT even for older children (1.20 m max.). If
the car seat has not already been ordered
with the XL kit, it can be retrofitted with it.
The XL-Kit consists of:
backrest cushion long, incl. headrest
 beltpads for the shoulder, pair
adapter plate (if thorax supports are used)
wedge-shaped pad, long
• First remove the already installed back
cushion, incl. the wedge-shaped compensati-
on cushion.
• Loosen the straps as far as possible and
remove the gray straps from the Y-connector
(fig. 2)
• Press the release button (Fig. 3) and pull the Y-
connector on the back of the car seat up as far
as it will go - until the gray 25 mm strap stops
and is visible only a few inches.

• Pass the strap ends of the beltpad through 
the openings below the headrest (Fig. 4 + 5)
and hook them into the Y-connection part.
The Y-connector remains in place as seen in 
Fig. 5.
ATTENTION: the 25 mm strap on the front of
the seat has no longer any function. Please do
not pull it anymore!!!
• The previously removed gray straps must now
be inserted into the two adjusters CORRECTLY
- see Fig. 6. Please note the course of the
arrows!
The length of the shoulder strap can then be
changed by means of the two adjusters,
which are located at the end of the beltpads.
The tightening is achieved by pulling on the
strap ends. For loosening press the gray
button off the adjuster and pulled on the
shoulder strap.
The belt must be easy to move without
exaggerated effort. If this is not the case, the
belt was threaded wrong !!!

• Page 11 •
Fig. 8
Fig. 7
Fig. 9
• If thorax supports were installed, the adapter
plate must now be attached - see Fig. 7.
To do this, the headrest must be pulled out
completely and two strips of self-adhesive loop
tape (included in delivery, adhering to the
adapter plate) to be glued to the red marked
area.
Now, the already existing mounting plate for
the thorax supports (square plate, about 20 
x 20 cm) must be removed from the car seat
back and be clamped at the height of the just
mounted adapter plate - see Fig. 8.
Now it is also advisable to adjust the thorax
supports to the height that suits the child - 
assuming you have previously taken your
measurements.
• Regardless of whether or not the thorax
supports are installed, the long wedge-shaped
cushion must now be attached to the lower 
edge of the back - see Fig. 9.
• The last step is to install the long back cushion
, including the positioning of the headrest.
Pass the thorax supports through the
appropriate longitudinal slots and then wrap
the excess pad around the wedge-shaped
pillow . Make sure that it does not wrinkle.
• The height of the
headrest can then
be adjusted to the
required height by
means of the
gray lever .

V. Using the optional accessories
5.1 ISOFIX-adapter
Installation:
1. Let the installation of the seat and its adjustment been demonstrated to you by the
technician.
2. Open the setscrews on the left and right and pull 
the bracket out to the rear.
3. Adjust the back rest of the car's seat to the required angle,
taking advantage of the space created to the car's back
pad. Slide the ISOFIX adapter on both sides backwards in
the direction of the backrest until you hear the locking of
the two ISOFIX tongues in the vehicle's ISOFIX
mounting (two clicks).
4. Push the car seat towards the backrest of the vehicle until
both touch and are slightly under tension. This prevents
vibrations while driving.
5. Close the two setscrews left and right. In addition, 
the two ISOFIX tongues must be protected against
unattempt opening, which is why both screws 
must be tightened.
6. Ensure that both ISOFIX tongues are engaged by a
double-sided pulling test.
Removal Note:
1. Open the two screws .
2. Move them forwards in the direction of the car seat,
releasing the grid connection of the system. It may
be necessary to compensate for the pressure of the
seats padding so that the connection can be solved.
3. The car seat can now be removed from the vehicle.

5.2 Clamp bow
Installation:
1. Let the installation of the seat and adjustment
of it be shown to you during the delivery.
2. Open the setscrews on the left and right 
and pull the bracket to the rear.
3. Adjust the back rest of the car's seat to the
required angle, taking advantage of the space
created to the car's back pad. Now push the
clamp on both sides backwards in the direc-
tion of the backrest, until it sinks into the gap
of the car seat and seat upholstery and
remains firm.
4. Push the car seat against the backrest of the
vehicle until it rests flat.
5. Now close the two setscrews left and right.
6. Whether the offset of the bow must be
directed upwards or downwards depends on
the construction of the respective passenger
car seats.
Removal Note:
1. Pull the car seat including the clamp out of
the gap of the car seat.

5.3 Security tray
Installation:
1. Let the installation of the seat and adjustment of it be
shown to you during the delivery.
2. Put the support and safety pad on the car seat 
after sitting your child into it and strapping it on.
3. Secure the padding using the supplied Velcro straps
, which are fastened to the back of the car seat.
4. Your child's arms should rest on the table, which
leads to an upright seating position. This supports the
upper body.
5. Make sure to avoid the risk of toys, which may be on
the upholstery. Do not use hard, solid or even sharp-
edged objects!
5.4 Lateral supports
1. HERNIK GmbH is not allowed to injure (drill, screw)
the body of the STARLIGHT-NXT. Nevertheless it was
very important to us to offer lateral supports for 
children with weak trunk muscles, so we decided for a
fixation solution, which uses Velcro for sufficient
stability and also provides flexibility.
2. In order to change the position of the pads, it must
first be carefully released by gently turning the Velcro
connection. Afterwards, the pad can be arranged freely.
IMPORTANT: For a stable fit, the pad should be pressed
with high pressure while turning back and forth on the
back of the STARLIGHT-NXT. This creates a firmer hold
of the Velcro elements!
V. Using the optional accessories

5.5 Abduction block
1. The abduction wedge helps your child to 
reach a predetermined distance between the
knees. In order to loosen or tightening the 5-
point belt, the wedge must be removed.
Open the clamp and remove the wedge 
upwards.
2. The wedge should be against the seat
upholstery as shown in the picture. The depth
of the wedge can be adjusted. For this
purpose, both hexagon screws must be
opened and offset under the seat.
3. The wedge should always be used while
driving (if chosen as an option), otherwise
your child could be injured by the mounting.
4. The lever can be changed in its position by 
gently pulling it forward without moving the
screw connection. Make sure it is up and not
out of the way, otherwise your child's calves
may come into contact with it.
5.6 Angular adjustment
1. If the seat angle provided by the vehicle seat
is insufficient, the seat angle of the car seat
can be increased by the (extended) child seat
angle adjustment . For this purpose, the 
screw left and right has to be opened and 
another hole to be selected. Then tighten the
screws back.
2. For safety reasons, here is no quick release
possible!

5.7 Foot rest / foot roll
1. The tabs are fixed below the car seat by 
means of set screws on the base mount, so
that the depth can be adjusted.
2. The angle of the handrails can be varied by
opening the quick release lever . Care 
should be taken to ensure that the levers are
in a position that does not cause harm!
3. To adjust the height of the footrest, the
screws on the left and right must be 
opened. Now the height can be stepless
selected. Then please tighten the screws
again.
5.8 Swivel
1. To simplify the daily transfer to the vehicle, we
recommend our swivel adapter, which let the
car seat turn outwards by 90 °. For technical
reasons, only ONE direction of rotation is
possible. For a later change in the other
direction, the car seat must be rebuilt in our
house. The use of the ISOFIX adapters or the
clamp are recommended!
2. To turn the chair, the handle must be pulled 
up and the chair moved at the same time. The
optional footrest stops to avoid collisions with
the front passenger seat and the B-pillar.
Pay attention when rotating your child's legs!
3. After the transfer, simply turn the IPAI-NXT back
to the starting position and pay attention to the
"click" sound, in which the tongue snaps back 
into the catch.
