INSTALLATION
Install in reverse order of removal. Be careful of the following:
 After installation is completed, adjust and check A/T position. Refer to AT-207, "
Adjustment of A/T Position"
and AT-207, "Checking of A/T Position".
Adjustment of A/T PositionINFOID:0000000001327385
1. Loosen nut of control rod.
2. Place PNP switch and selector lever in “P” position.
3. While pressing lower lever toward rear of vehicle (in “P” position
direction), tighten nut to the specified torque. Refer to AT-206,
"Control Rod Removal and Installation".
CAUTION:
Do not push the bracket.
Checking of A/T PositionINFOID:0000000001327386
1. Place selector lever in “P” posit ion, and turn ignition switch ON.
2. Check selector lever can be shifted to other than “P” position when brake pedal is depressed. Also check
selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Check the selector lever stops at each position wit h the feel of engagement when it is moved through all
the positions. Check whether or not t he actual position the selector lever is in matches the position shown
by the shift position indicator and the transmission body.
5. The method of operating the lever to individual positions cor- rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Check the back-up lamps illuminate only when lever is placed in the “R” position. Check the back-up lamps does not illuminate
when selector lever is pushed against “R” position in the “P” or
“N” position.
8. Check the engine can only be started with the selector lever in the “P” and “N” positions. (With selector lever in the “P” position,
engine can be started even when selector lever is moved for-
ward and backward.)
9. Check transmission is locked completely in “P” position.
10. When selector lever is set to manual shift gate, check manual mode is displayed on combination meter. Shift selector lever to “+” and “-” sides, and check set shift position changes. (Only while a vehicle is oper-
ating.)

DescriptionINFOID:0000000001327387
 The mechanical key interlock mechanism also operates as a shift lock:With the ignition switch turned to ON, the selector le ver cannot be shifted from “P” position to any other posi-
tion unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” position to any other position.
The key cannot be removed unless the selector lever is placed in “P” position.
 The shift lock and key interlock mechanisms are contro lled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612929
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
Precaution Necessary for Steering Wh eel Rotation After Battery Disconnect
INFOID:0000000001612931
NOTE:
 This Procedure is applied only to models with Intell igent Key system and NVIS/IVIS (NISSAN/INFINITI
VEHICLE IMMOBILIZER SYSTEM - NATS).
 Remove and install all control units after disconnecti ng both battery cables with the ignition knob in the
″ LOCK ″ position.
 Always use CONSULT-III 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
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.
If steering wheel rotation is required when battery pow er 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-III.

< SERVICE INFORMATION >
REFRIGERATION SYSTEM
Evaporator intake air temperature is less than 20°C (68 °F).
Engine is running at speeds less than 1,500 rpm.
This is because the V-6 compressor prov ides a means of “capacity” control.
2. The V-6 variable compressor provides refrigerant c ontrol under varying conditions. During cold winters, it
may not produce high refrigerant pressure discharge (compared to previous units) when used with air
conditioning systems.
3. A “clanking” sound may occasionally be heard during re frigerant charge. The sound indicates that the tilt
angle of the wobble (swash) plate has changed and is not a malfunction.
4. For air conditioning systems with the V-6 compresso r, the clutch remains engaged unless: the system
main switch, fan switch or ignition switch is tur ned OFF. When ambient (outside) temperatures are low or
when the amount of refrigerant is insufficient, t he clutch is disengaged to protect the compressor.
DESCRIPTION
General
The variable compressor is a swash plate type that c hanges piston stroke in response to the required cooling
capacity.
The tilt of the wobble (swash) plate allows the piston’ s stroke to change so that refrigerant discharge continu-
ously change from 14.5 to 184 cm
3 (0.885 to 11.228 cu in).
