2. Check fluid level.
Fluid level should be check using ªHOTº range on A/T fluid
level gauge at fluid temperatures of 50 to 80ÉC (122 to 176ÉF)
after vehicle has been driven approximately 10 minutes in
urban areas after engine is warmed up. But it can be checked
at fluid temperatures of 30 to 50ÉC (86 to 122ÉF) using ªCOLDº
range on A/T fluid level gauge for reference after engine is
warmed up and before driving. However, fluid level must be
rechecked using ªHOTº range.
a. Park vehicle on level surface and set parking brake.
b. Start engine and then move selector lever through reach gear
range, ending in ªPº.
c. Check fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe it clean with lint-free
paper.
e. Re-insert A/T fluid level gauge into charging pipe as far as it
will go.
f. Remove A/T fluid level gauge and note reading. If level is at
low side of either range, add fluid through the speedometer
cable hole.
Use genuine NISSAN CVT fluid (NS-1) or exact equivalent.
CAUTION:
Do not overfill.
CAUTION:
SMA051D
Firmly fix the A/T fluid level gauge using a lip attached to the
fluid charging pipe.

TCM FUNCTION=NLAT0014S03The function of the TCM is to:
+Receive input signals sent from various switches and sensors.
+Determine required line pressure, shifting point and lock-up operation.
+Send required output signals to the step motor and the respective solenoids.
INPUT/OUTPUT SIGNAL OF TCMNLAT0014S04
Switches, sensors and actuators Function
InputPNP switch Detects select lever position and sends a signal to TCM.

Supplemental Restraint System (SRS)“AIR
BAG”and“SEAT BELT PRE-TENSIONER”
NLBR0081The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER” used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of
collision. The SRS system composition which is available to NISSAN MODEL V10 is as follows (The compo-
sition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steer-
ing wheel), front passenger air bag module (located on the instrument panel on passenger side), front seat
belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of front
seat), side air bag (satellite) sensor, diagnosis sensor unit (one of components of air bags for a frontal
collision), wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To avoid rendering the SRS inoperative, 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 should be per-
formed by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
SBR686C
Precautions for Brake SystemNLBR0002+Recommended fluid is brake fluid“DOT 4”.
+Never reuse drained brake fluid.
+Be careful not to splash brake fluid on painted areas.
+To clean or wash all parts of master cylinder, disc brake
caliper and wheel cylinder, use clean brake fluid.
+Never use mineral oils such as gasoline or kerosene. They
will ruin rubber parts of the hydraulic system.
+Use flare nut wrench when removing and installing brake
tube.
+Always torque brake lines when installing.
+Burnish the brake contact surfaces after refinishing or
replacing rotors, after replacing pads, or if a soft pedal
occurs at very low mileage.
Refer to“Brake Burnishing Procedure”,“ON-VEHICLE
SERVICE”, BR-7.
WARNING:
+Clean brake pads with a waste cloth, then wipe with a dust
collector.
