Safety instructions
The automatic frunk control was designed to enable convenient and safe
opening and closing of the front cover (frunk). Nevertheless, as such it does
not replace the visual inspection. Therefore, always check that your frunk is
securely closed before starting a journey. In any case, the safety instructions
marked "🚫CAUTION:..." in these instructions must be observed. In case of
disregard of the safety instructions and resulting damages to the AMPTech
components or even vehicle parts, the warranty claim as well as any liability
for damages or consequential damages expires due to own fault (see GTC's
on www.amptech.store/agb/, V. Liability). If you have any questions or
problems with the Frunkautomatic, please contact AMPTech under the
phone number [phone] or the email [email protected].

Installation guide
Before proceeding to the removal of the inner lining, it is advisable to expose
storage areas for the parts removed in the course of the installation. In
addition, it is helpful to keep the clamps and screws that are removed
sorted.
Remove cladding
● Remove the four interior trim panels arranged around the front
storage compartment. To do this, pull the panels upwards with a jerk
(Figure 1).
Figure 1: Plastic cladding in the frunk
● Remove the front storage compartment carpet trim by reaching
under the rubber lip and separating the carpet trim from the rubber
lip
● Disconnect the two plugs for the storage compartment lighting and
the plug for the pushbutton. The plugs are locked according to the
barb principle
● Then lift out the carpet lining
● The plastic tray under the fairing is fixed with 20 hexagonal screws
(10mm). Loosen the screws (Figure 2)

● Lift out the plastic tray
Replace lifting arms
● Remove the lift arms by levering the locking cotter pin with the
slotted screwdriver and pulling on the respective end of the lift arm
by hand until the lift arm releases at the attachment point (Figure 3)
Figure 3: Loosening the lifting arms
● Loosen the joints at the lower attachment points of the lifting arms
using a socket wrench (13mm) (Figure 4)

Figure 4: Lower attachment point
● Use the adapter plates included in the scope of delivery and screw
them to the lower attachment points of the lift arms using the screws
included in the scope of delivery. The adapter plates are marked with
"L" (left) and "R" (right) and refer to the left and right side of the vehicle
in the direction of travel. The arrows on the adapter plates indicate the
corner of the adapter plate that is further up when attached. The
curved part of the adapter plate is guided over the sheet metal edge
marked with the red arrow (Figure 5).

💡Tip
Loosen one lift arm and attach the new lift arm to
the lower attachment point first. After the second
lift arm has been loosened, press both lift arms
against the joint at the upper attachment point so
that the lift arms engage. A second person should
be used to replace the lifting arms.
● The lifting arms for the automatic frunk are pressed against the ball
of the ball joint with the locking split pin until they engage. A "click"
sound is heard when they engage. The front hood must be held in
position for this if necessary.
● Test with both hands whether the front cover can be moved without
any problems
Modify clamping unit
● Loosen the 7 hex head screws (10mm, hex) that secure the plastic
cover above the Tesla emblem (Figure 6)
Figure 6: Screwing of the front plastic cover
● Loosen the two pin clips at the ends of the plastic cover. These are
located underneath the plastic cover (Figure 7)
