CLUTCH AND BAND CHART

*1: Operates when overdrive control switch is set in “OFF” position.

*2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not con-
tract because oil pressure area on the “release” side is greater than that on the “apply” side.

*3: Oil pressure is applied to 4th “apply” side in condition *2 above, and brake band contracts.

*4: A/T will not shift to 4th when overdrive control switch is set in “OFF” position.

: Operates.

A: Operates when throttle opening is less than 3/16, activating engine brake.

B: Operates during “progressive” acceleration.

C: Operates but does not affect power transmission.

D: Operates when throttle opening is less than 3/16, but does not affect engine brake. Shift positionRever

Stop Signal:
At the end of each transmission, a stop operation, in-operation, or internal malfunction message is delivered to
the auto amp. This completes one data transmission and control cycle.
AIR MIX DOOR CONTROL (AUTOMATIC TEMPERATURE CONTROL)
The air mix door is automatically controlled so that in-vehicle temperature is maintained at a predetermined
value by the temperature setting, ambient temperature, in-vehicle temperature and amount of sunload.
FAN SPEED CONTROL
Blower speed is automatically controlled by the temperature setting, ambient temperature, in-vehicle tempera-
ture, intake temperature, amount of sunload and air mix door position.
With FAN control dial set to AUTO, the blower motor starts to gradually increase air flow volume.
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from flow-
ing.
INTAKE DOOR CONTROL
The intake doors are automatically controlled by the temperature setting, ambient temperature, in-vehicle tem-
perature, intake temperature, amount of sunload and ON-OFF operation of the compressor.
OUTLET DOOR CONTROL
The outlet door is automatically controlled by the temperature setting, ambient temperature, in-vehicle temper-
ature, intake temperature and amount of sunload.
MAGNET CLUTCH CONTROL
The ECM controls compressor operation using input signals from the throttle position sensor, refrigerant pres-
sure sensor (or dual-pressure switch) and auto amp.
SELF-DIAGNOSTIC SYSTEM
The self-diagnostic system is built into the auto amp. to quickly locate the cause of symptoms.

RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and LubricantsELS000C8
*1: For further details, see “SAE Viscosity Number”.
*2: Never use API CG-4.
*3: Use Genuine NISSAN Anti-freeze Coolant (L250) or equivalent in its quality, in order to avoid possible aluminum corrosion w ithin the
engine cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be
covered by the warranty even if such incidents occurred during the warranty period.
*4: Contact a NISSAN dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRON
TM III/
MERCONTM Automatic Transmission Fluid.
