Part name Function
Torque converter Increases engine torque and transmits it to the transaxle.
Oil pump Utilizes a vane-type oil pump that is driven by the engine through the oil pump drive chain in order to
increase efficiency of pump discharge volume in low-speed zone and optimize pump discharge volume
in high-speed zone. Discharged oil from oil pump is tr ansmitted to control valve. It is used as the oil of
primary and secondary pulley operation, the oil of clutch operation, and the lubricant for each part.
Forward clutch The forward clutch is wet and multiple plate type clutch that consists of clutch drum, piston, drive plate,
and driven plate. It is a clutch to move the vehicle forward by activating piston hydraulically, engaging
plates, and directly connecting sun gear and input shaft.
Reverse brake The reverse brake is a wet multiple-plate type brake that consists of transaxle case, piston, drive plate,
and driven plate. It is a brake to move the vehicle in reverse by activating piston hydraulically, engaging
plates, and fixing planetary gear.
Internal gear The internal gear is directly connected to forward clutch drum. It is a gear that moves the outer edge of
pinion planet of planet carrier. It transmits power to move the vehicle in reverse when the planet carrier
is fixed.
Planet carrier Composed of a carrier, pinion planet, and pinion shaft. This gear fixes and releases the planet carrier in
order to switch between forward and reverse driving.
Sun gear Sun gear is a set part with planet carrier and internal gear. It transmits transmitted force to primary fixed
sheave. It rotates in forward or reverse direction according to activation of either forward clutch or re-
verse brake.
Input shaft The input shaft is directly connected to forward clutch drum and transmits traction force from torque con-
verter. In shaft center, there are holes for hydraulic distribution to primary pulley and hydraulic distribution
for lockup ON/OFF.
Primary pulley It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the chain belt. The groove width changes according to wrapping radius of steel belt and pulley from low status to
overdrive status continuously with non-step. It is controlled with the oil pressures of primary pulley and
secondary pulley.
Secondary pulley
Chain belt
Manual shaft When the manual shaft is in the P position, the parking rod that is linked to the manual shaft rotates the
parking pole. When the parking pole rotates, it engages with the parking gear, fixing the parking gear. As
a result, the secondary pulley that is integrated with the parking gear is fixed.
Parking rod
Parking pawl
Parking gear
Output gear
The deceleration gears are composed of 2 stages: primary deceleration (output gear, idler gear pair) and
secondary deceleration (reduction gear, final gear pair). All of these gears are helical gears.

INFOID:0000000009464202
CVT FLUID COOLER SCHEMATIC
COMPONENT DESCRIPTION
CVT Oil Warmer
• The CVT oil warmer (1) is installed on the front part of transaxle
assembly.
• When engine is started while engine and CVT are cold, engine coolant temperature rises more quickly than CVT fluid tempera-
ture. CVT oil warmer is provided with two circuits for CVT and
engine coolant respectively so that warmed engine coolant warms
CVT quickly. This helps shorten CVT warming up time, improving
fuel economy.
• A cooling effect is obtained when CVT fluid temperature is high.
Heater Thermostat
• The heater thermostat (1) is insta lled on the front part of transaxle
assembly.
• The heater thermostat open and close with set temperature.
SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM : System DescriptionINFOID:0000000009464203
The shift lever cannot be shifted from the “P” positi on unless the brake pedal is depressed while the ignition
switch is set to ON. The shift lock is unlocked by turn ing the shift lock solenoid ON when the ignition switch is
set to ON, the park position switch is turned ON (selec tor lever is in “P” position), and the stop lamp switch is
turned ON (brake pedal is depressed) as shown in the oper ation chart in the figure. Therefore, the shift lock
solenoid receives no ON signal and the shift lock remains locked if all of the above conditions are not fulfilled.
However, selector operation is allowed if the shift lock release button is pressed.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951708
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. Information necessary to service t he system safely is included in the SR and SB section 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 SR section.
• 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.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Service Notice and Precautions for TPMSINFOID:0000000009464472
WARNING:
Radio waves could adversely affect electrical medi cal equipment. Those who use a pacemaker should
contact the electrical medical equipment manu facturer for possible influences before use.
• Low tire pressure warning lamp blinks for 1 minute, then turns ON when any malfunction occurs except low
tire pressure. Erase the self-diagnosis memories for Tire Pressure Monitoring System (TPMS), or register
the ID to turn low tire pressure warning lamp OFF. For ID registration, refer to WT-25, "Work Procedure"
.
• ID registration is required when replacing or rotating wheels, replacing tire pressure sensor or BCM. Refer to WT-25, "Work Procedure"
.
• For easy fill tire alert function, refer to the following. WT-9, "Easy Fill Tire Alert Function"
- When inflating the tires, park the vehicle in the safe area and ensure the safety of the working area.
- Read and understand the easy fill tire alert function prior to use.
- Inflate the tires one at a time.
- If there is no response for approximately 15 seconds or mo re after inflating the tires, cancel the use of the
easy fill tire alert function or move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.
The air filler pressure may be weak or out of service area.
- Despite the high-precision TPMS pressure sensor, an i ndicated value may differ from that of the pressure
gauge.
- Air pressure is measured rather high due to the rise in tire air temperature after driving.
- If TPMS is malfunctioning, the easy fill tire alert is unusable.
• Replace grommet seal, valve core and valve cap of tire pressure sensor in TPMS when replacing each tire
by reaching the wear limit. Refer to WT-57, "Exploded View"
.
• Because the tire pressure sensor conforms to No rth America radio law, the following items must be
observed.
- The sensor may be used only in North America.
- It may not be used in any method other than the specified method.
- It must not be disassembled or modified.

System DescriptionINFOID:0000000009464484
When the vehicle has reached a speed of 40 km/h (25 MPH) or greater, the BCM receives a signal transmitted
from the tire pressure sensors/transmitters installed in each wheel. If the BCM detects low inflation pressure or
a system malfunction, it sends a signal to the combi nation meter via CAN communication to illuminate the low
tire pressure warning lamp. In addition, a warning message will be displayed in the vehicle information display.
Refer to the Owner’s Manual for additional information.
The tire pressure monitoring system (TPMS) has Easy fill ti re alert function to aid in tire inflation. Refer to WT-
9, "Easy Fill Tire Alert Function".
Low Tire Pressure Warning Lamp and Display Indications
Easy Fill Tire Alert FunctionINFOID:0000000009464485
NOTE:
When beginning tire inflation, it takes a few seconds for t he Easy fill tire alert to function. If there is no
response for approximately 15 seconds or more, cancel t he Easy fill tire alert function and move the vehicle
approximately 1 m (3.2 ft) backward or forward to try again.
• The Easy fill tire alert function operates only when t he select lever position is in P-range with the ignition
switch ON.
• This function informs the driver with a visual and audible indication that the recommended COLD tire pres-
sure has been reached.
• The hazard warning lamps blink when the recommended COLD tire pressure has been reached. After the recommended COLD tire
pressure has been reached, the horn sounds once and the hazard
warning lamps stop blinking.
• If the tire pressure value is equal to or greater than 30 kPa (0.31
kg/cm
2, 4 psi) more than the recommended COLD tire pressure,
the hazard warning lamps flash and horn sounds three times.
• To return the tire to the recommended COLD tire pressure, deflate
the tire until the horn sounds once and the hazard warning lamps
stop blinking.
