                                              PRECAUTIONS
                                                                                                    [VQ35DE]
PRECAUTIONS
[VQ35DE]                                                               PFP:00001
                                                                                                                      A
Precautions Necessary for Steering Wheel Rotation After Battery Disconnect
                                                                                                           ABS00B3H

NOTE:
q    This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI EM
     VEHICLE IMMOBILIZER SYSTEM - NATS).
q    Remove and install all control units after disconnecting both battery cables with the ignition knob in the
     LOCK position.                                                                                               C
q    Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
     work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NVIS/IVIS, an electrically controlled steering lock D
mechanism 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.                                                                   E
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE                                                                                                   F
1.   Connect both battery cables.
     NOTE:
     Supply power using jumper cables if battery is discharged.                                                       G
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             H
     rotated.
4.   Perform the necessary repair operation.
5.   When the repair work is completed, return the ignition switch to the LOCK position before connecting             I
     the battery cables. (At this time, the steering lock mechanism will engage.)
6.   Perform a self-diagnosis check of all control units using CONSULT-II.
                                                                                                                      J
Precautions for Drain Engine Coolant                                                                       ABS005ZK


Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel Piping                                                                  ABS005ZL   K
q    Before starting work, make sure no fire or spark producing items are in the work area.
q    Release fuel pressure before disconnecting and disassembly.                                                      L
q    After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and Disassembly                                                                    ABS005ZM

                                                                                                                      M
q    When instructed to use special service tools, use the specified tools. Always be careful to work safely,
     avoid forceful or uninstructed operations.
q    Exercise maximum care to avoid damage to mating or sliding surfaces.
q    Cover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
q    Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.
q    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.
Precautions for Inspection, Repair and Replacement                                                         ABS005ZN


Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and Installation                                                                  ABS005ZO


q    Use torque wrench to tighten bolts or nuts to specification.

                                              PRECAUTIONS
                                                                                                      [VQ35DE]
q    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 speci-
     fied, do exactly as specified.
q    Replace with new liquid gasket, packing, oil seal or O-ring.
q    Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
     any restriction and blockage.
q    Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
     Before assembly, oil sliding surfaces well.
q    Release air within route when refilling after draining engine coolant.
q    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.
q    After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil and
     exhaust systems for leakage.
Parts Requiring Angle Tightening                                                                              ABS005ZP


q    Use an angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts:
