Removing and Installing Lug Nut Covers
If your Model 3 is equipped with lug nut covers, you must remove them to access the
lug nuts.
To remove a lug nut cover:
1. Insert the curved part of the lug nut cover
tool (located in the glovebox for some
vehicles) into the hole at the base of the
Tesla "T".
Note: The lug nut cover tool can also be
purchased at an auto parts store or
through online retailers.
2. Maneuver the lug nut cover tool so that it
is fully inserted into the hole in the lug nut
cover.
3. Twist the lug nut cover tool so that the
curved part is touching the middle of the
lug nut cover.
4. Firmly pull the lug nut tool away from the
wheel until the lug nut cover is released.
To install the lug nut cover:
1. Align the lug nut cover into position.
2.
Push firmly on the lug nut cover until it
fully snaps into place.Caution: Make sure the lug nut cover
is fully secure before driving to
prevent it from falling off.
Wheel Configuration
If you are installing new wheels or swapping
them for different ones, update your vehicle

1.Get isopropyl alcohol and test it on a non-
visible painted surface of your vehicle to
confirm that it does not damage or
remove the paint.
2. Clean the mounting site with isopropyl
alcohol and allow to dry for at least one
minute.
3. Fully remove the protective tape from the
adhesive at the top of the bracket and
partially remove the tape from the top of
the adhesive on each side. Leave the
bottom half of the tape on the sides in
place and fold the unattached tape
outward for easy removal after aligning
the bracket to the bumper.
4. While tilting the top of the license plate
bracket away from the bumper (to prevent adhering it to the wrong location),
align the bottom center of the license
plate bracket with the middle of the grille
as shown.
Note: Be as precise as possible when
aligning the bracket because you will be
unable to reposition it once adhered to
the bumper.
5. While correctly aligned, move the top of
the bracket against the bumper and applypressure so that it is held in place by the
adhesive.
6. Remove the remaining tape from the sides
of the bracket then press the entire
bracket firmly against the bumper,
ensuring the bracket is held in place by all
adhesive areas.
7. Once the bracket is securely mounted, use
the four supplied screws to attach your
license plate to the bracket (tighten to 3
Nm/2.2 ft-lbs).
