2008 NISSAN LATIO battery replacement

EM-4
< SERVICE INFORMATION >
PRECAUTIONS
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-III.
Precaution for Drain CoolantINFOID:0000000001702463
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001702464
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000001702465
• When instructed to use special service tools, use the specified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001702466
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000001702467
• Use torque wrench to tighten bolts or nuts to specification.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the
ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
• Release air within route after draining coolant.
• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped).
Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for
leakage.
Parts Requiring Angular TighteningINFOID:0000000001702468
• Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Camshaft sprocket (INT)
- Main bearing cap bolts
- Connecting rod cap nuts
- Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular
tightening)

FUEL SYSTEM
FUEL SYSTEM
Checking Fuel LineINFOID:0000000001703097
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionINFOID:0000000001703098
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the work area.
• Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
• Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
• Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
CAUTION:
• Use gasoline required by the regulations for octane number. Refer to GI-4, "
Precaution for Fuel
(Unleaded Regular Gasoline Recommended)".
• Before removing fuel line parts, perform the following procedures:
- Release fuel pressure from the fuel lines. Refer to EC-78, "
Fuel Pressure Check".
- Disconnect the battery ground cable.
• Always replace O-rings and clamps with new ones.
• Do not kink or twist tubes when they are being installed.
• Perform work on level surface.
• Do not tighten hose clamps excessively to avoid damaging hoses.
• After connecting fuel tube quick connectors, make sure quick connectors are secure.
Ensure that connector and resin tube do not contact any adjacent parts.
• After installing tubes, make sure there is no fuel leakage at connections in the following steps.
- Apply fuel pressure to fuel lines by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube connections.
- Start engine and rev it up and check for fuel leaks at connections.
• Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used, the
MIL may come on.
• For servicing “Evaporative Emission System” parts, refer to EC-31
.
• For servicing "On Board Refueling Vapor Recovery (ORVR)" parts, refer to EC-38
.

SIDE CURTAIN AIR BAG MODULE
• When servicing the SRS, do not work from directly in front of air bag module.
• Always place the curtain air bag module with deployment side facing upward.
• Do not reuse center pillar upper garnish if removed.
CAUTION:
• Before servicing SRS, turn the ignition switch OFF, disconnect both battery cables and wait at least
3 minutes.
• Do not use old bolts after removal; replace with new bolts.
• Do not insert any foreign objects (screwdriver, etc.) into air bag module or harness connectors.
• Do not disassemble air bag module.
• Do not expose the side curtain air bag module to temperatures exceeding 90°C (194°F).
• Replace the side curtain air bag module if it has been dropped
or sustained an impact.
• Do not allow oil, grease or water to come in contact with the
side curtain air bag module.
• Do not attempt to repair or replace damaged direct-connect
SRS component connectors. If a direct-connect harness con-
nector is damaged, the harness must be replaced.
1. Disconnect both the negative and positive battery cables, then wait at least 3 minutes.
2. Remove the headlining. Refer to EI-45
.
3. Disconnect side curtain air bag module connector.
NOTE:
For removal/installation of the direct-connect SRS connectors,
refer to SRS-6, "
Direct-connect SRS Component Connectors".
4. Remove the bolts in order starting at the rear, then remove the
side curtain air bag module.
INSTALLATION
Installation is in the reverse order of removal.
• For removal/installation of the direct-connect SRS connectors, refer to SRS-6, "
Direct-connect SRS Compo-
nent Connectors".
• After replacement of side curtain air bag module, perform self-diagnosis to check that no malfunction is
detected. Refer to SRS-18, "
SRS Operation Check".
