Loosen the nut on the battery hold down on the top of the lead-acid battery with a 10mm socket. To
release the battery hold down, unhook and slide the
strap back. If needed, tilt the battery hold down
backward so it does not slip into the vehicle.

Using the battery handle, carefully remove the lead- acid battery, taking care not to touch or damage the surrounding components.
WARNING: When lifting out the lead-acid
battery, stand in front of the vehicle and use
proper lifting technique. The lead-acid battery
weighs approximately 25 lb (12 kg). Failure to
do so may cause serious injury.
11.
Inspect the new lead-acid battery to ensure it has a
red plug in the casing on the positive (+) terminal
side. If the new lead-acid battery does not have a red plug, use a small trim tool to transfer the red plug
from the old battery to the new one.
CAUTION: Dispose of the old lead-acid battery
according to local laws, such as dropping it off

at a battery recycling facility. Keep the lead-
acid battery upright and place it on a towel or
piece of cardboard when transporting it.
Installation:
1.
Carefully maneuver the new lead-acid battery into
place, taking care not to touch or damage nearby
components.
2.
Install the lead-acid battery hold down and use a 10mm socket to tighten the nut that secures it to the 12V battery. Torque the nut to 6 Nm (4.4 ft-lb).

Wall plug adapter error - Charge rate reduced
Plug adapter fully into Mobile Connector and retry
What this alert means:
Your Mobile Connector is unable to communicate with the wall plug adapter. Because your Mobile Connector cannot
identify the type of wall outlet the wall plug adapter is connected to, charge current is automatically reduced to 8A.
What to do:
1.
Unplug your Mobile Connector, including the wall plug adapter, completely from the wall outlet.
2.
Make sure the connection between the wall plug adapter and the main body of your Mobile Connector is secure.
a.
Disconnect the wall plug adapter completely from the main body of your Mobile Connector.
b.
Fully reinsert the wall plug adapter into the main body of your Mobile Connector by pushing it into the socket until it snaps into place.
3.
Try charging again by plugging the Mobile Connector, including wall plug adapter, fully into the wall outlet.
4.
If the alert persists, try using a different wall plug adapter (see steps above to make sure the adapter is fully
connected to your Mobile Connector).
a.
If the alert is no longer present, the issue is likely with the wall plug adapter you were using previously.
b.
If the alert persists, the issue is likely with your Mobile Connector.
If needed, obtain another wall plug adapter or Mobile Connector. In the meantime, you can continue to charge with
the same equipment. The charge rate will be reduced, as charge current will be limited to 8A while this condition
persists.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle
