REMOVAL

CAUTION / NOTICE / HINT

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during fuel pressure sensor removal/installation are shown below.

Necessary Procedures After Parts Removed/Installed/Replaced

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed
*1: for Hatchback
Battery terminal is disconnected/reconnected	Perform steering sensor zero point calibration	Lane Control System (for Gasoline Model)
		Pre-collision System (for Gasoline Model)
		Lighting System (w/ AFS)(EXT)
	Initialize back door lock*1	Power Door Lock Control System (for Hatchback, Gasoline Model)
Replacement of fuel pressure sensor Replacement of throttle body with motor assembly Cleaning the deposits from the throttle body with motor assembly Gas leak from exhaust system is repaired	Inspection after repair	Poor idle, etc. Engine start function, etc.

CAUTION:

Never perform work on fuel system components near any possible ignition sources.
Vaporized fuel could ignite, resulting in a serious accident.
Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.
Sparks could cause vaporized fuel to ignite, resulting in a serious accident.
To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.

NOTICE:

After the ignition switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the ignition switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Audio and Visual System (for Gasoline Model))
After the engine switch is turned off, the radio and display receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, make sure to wait at least 85 seconds before disconnecting the cable from the negative (-) battery terminal. (for Navigation System)
This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.
