For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.

OPERATION PROCEDURE

1.

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

2.

Use the Intelligent Key or mechanical key to turn the ignition switch to the ACC position. At this time, the
steering lock will be released.

3.

Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.

4.

Perform the necessary repair operation.

5.

When the repair work is completed, return the ignition switch to the LOCK position before connecting the
battery cables. (At this time, the steering lock mechanism will engage.)

6.

Perform a self-diagnosis check of all control units using CONSULT. 

Parts Requiring Angular Tightening

INFOID:0000000010281957

• Use an angle wrench for the final tightening of the following engine parts. 
- Cylinder head bolts
- Main bearing cap bolts
- Timing sprocket bolts
- Crankshaft pulley bolt
- Wear compensation gear bolt
- Camshaft sprocket (for fuel pump) bolt
• Do not use a torque value for final tightening. 
• The torque value for these parts are for a preliminary step.
• Ensure thread and seat surfaces are clean and coated with engine oil. 

Precaution for Liquid Gasket

INFOID:0000000010281958

REMOVAL OF LIQUID GASKET

• After removing mounting nuts and bolts, separate the mating sur-

face using the seal cutter [SST:KV10111100 ( — )] (A) and remove
old liquid gasket sealing.

CAUTION:

Be careful not to damage the mating surfaces.

• Tap the seal cutter to insert it (B), and then slide it (C) by tapping

on the side as shown in the figure.

• In areas where the seal cutter is difficult to use, use a plastic ham-

mer to lightly tap the parts, to remove it.

CAUTION:

If for some unavoidable reason a tool such as a flat-bladed
screwdriver is used, be careful not to damage the mating sur-
faces.

LIQUID GASKET APPLICATION PROCEDURE

EM-364

< PRECAUTION >

[R9M]

PRECAUTIONS

1.

Using a scraper (A), remove the old liquid gasket adhering to the
gasket application surface and the mating surface.
• Remove the liquid gasket completely from the groove of the

gasket application surface, mounting bolts and bolt holes.

2.

Wipe the gasket application surface and the mating surface with
white gasoline (lighting and heating use) to remove adhering
moisture, grease and foreign materials.

3.

Attach the liquid gasket to the tube presser (commercial service
tool).
Use Genuine Liquid Gasket or equivalent.

4.

Apply the liquid gasket without breaks to the specified location
with the specified dimensions.
• If there is a groove for the liquid gasket application, apply the

gasket to the groove.

• As for the bolt holes, normally apply the gasket inside the

holes. If specified, it should be applied outside the holes.
Check to read the instruction in this manual.

• Within five minutes of gasket application, install the mating

component.

• If the liquid gasket protrudes, wipe it off immediately.
• Do not retighten after the installation.
• After 30 minutes or more have passed from the installation, fill the engine oil and coolant.

CAUTION:

If there are instructions in this manual, observe them.

Precaution for Diesel Equipment

INFOID:0000000010281959

CLEANLINESS

CLEANLINESS INSTRUCTIONS WHICH MUST BE FOLLOWED WHEN WORKING ON THE HIGH PRES-
SURE DIRECT INJECTION SYSTEM
Risks relating to contamination

The system is very sensitive to contamination. The risks caused by the introduction of contamination are:

• Damage or destruction of the high pressure injection system and the engine
• Seizing or leaking of a component
All After-Sales operations must be performed under very clean conditions. This means that no impurities (par-
ticles a few microns in size) get into the system during dismantling or into the circuits via the fuel unions.
The cleanliness principle must be applied from the fuel filter to the fuel injectors.
WHAT ARE THE SOURCES OF CONTAMINATION?

Contamination is caused by:

• Metal or plastic chips
• Paint
• Fibers:
- Boxes
- Brushes

- Paper
- Clothing
- Cloths
• Foreign bodies such as hair
• Ambient air
• Etc.

WARNING:

It is not possible to clean the engine using a high pressure washer because of the risk of damaging
connections. In addition, moisture may collect in the connectors and create electrical connection mal-
functions
INSTRUCTIONS TO BE FOLLOWED BEFORE ANY WORK IS CARRIED OUT ON THE INJECTION SYS-
TEM
• Check that you have the plugs for the unions to be opened (bag of plugs sold at the Parts Stores). Plugs are

to be used once only. After use, they must be thrown away (once used they are soiled and cleaning is not
sufficient to make them reusable). Unused plugs must be thrown away.

• Check that you have hermetically resealable plastic bags for storing removed parts. Stored parts will there-

fore be less subject to the risk of impurities. The bags must be used only once, and after use they must be
thrown away.

• Lint-free towelettes to be used for fuel pump related service purpose. The use of a normal cloth or paper for

cleaning purposes is forbidden. These are not lint-free and may contaminate the fuel circuit of the system.
Each lint-free cloth should only be used once.

INSTRUCTIONS TO BE FOLLOWED BEFORE OPENING THE FUEL CIRCUIT
• For each operation, use new thinner (used thinner contains impurities). Pour it into a clean receptacle.
• For each operation, use a clean brush which is in good condition (the brush must not shed its bristles).
• Use a brush and thinners to clean the connections to be opened.
• Blow compressed air over the cleaned parts (tools, cleaned the same way as the parts, connections and

injection system zone). Check that no bristles remain adhered.

• Wash your hands before and during the operation if necessary.
• When wearing leather protective gloves, cover these with latex gloves.
INSTRUCTIONS TO BE FOLLOWED DURING THE OPERATION
• As soon as the circuit is open, all openings must be plugged to prevent impurities from entering the system.

The plugs to be used are available from the Parts Stores. They must not, under any circumstances, be
reused.

• Close the hermetically sealed bag, even if it has to be reopened shortly afterwards. Ambient air carries con-

tamination.

• All components of the injection system that are removed must be stored in a hermetically sealed plastic bag

once the plugs have been inserted.

• The use of a brush, thinner, bellows, sponge or normal cloth is strictly forbidden once the circuit has been

opened. These items are likely to allow impurities to enter the system.

• A new component replacing an old one must not be removed from its packaging until it is to be fitted to the

vehicle.
