Ferrari 458 Italia Owner's Manual page 205

If the electric parking brake cannot be deactivated because the
battery is flat or there is a failure in the electrical system that
controls it and the vehicle needs to be moved, the emergency
release procedure described below must be performed.
• Take wrench for EPB emergency release out of the tool bag.
A
Warning
Wrench A may only be used by specialised workshop
technicians, as indicated on label C on the tool bag.
• Place the release wrench A in the hole
guard and turn clockwise: this loosens the parking brake cables.

Important note
To release the brake completely, the wrench needs to be turned
50 times, whereas it starts to be released after approximately
20 turns.
Once the electric parking brake has been manually released, the
EPB node records a failure at the next key-on and a special symbol
and the following message are displayed on the left TFT display:
"Parking Brake system revision. Go to dealer".
Warning
The parking brake resumes normal operation, but it is important
to go to the nearest workshop to have it calibrated and delete
any errors in the error memory.
Go to a Ferrari Service Centre.
Calibration is necessary for safety reasons.
