EPS SYSTEM
 The valve driving voltage to control the power steering solenoid
valve varies according to the vehicle speed.
OPERATION PRINCIPLE
During Parking (When Turning The Steering Wheel To The Right.)
1. Power steering solenoid valve is closed while a vehicle is stopped.
2. Pinion “1R”, “2R” and “3R” are closed depending on steering torque of steering wheel.
3. Oil pressure “P” in the gear housing assembly is the sum of oil pressures occurred in “2R” and “3R”. This
results in a light steering force because of high pressure.
During High-speed Operation
1. Power steering solenoid valve is opened during high-speed operation.
2. Pinion “1R”, “2R” and “3R” are closed depending on steering torque of steering wheel.
3. Oil pressure “2R” does not occur because the power steering solenoid valve is on full throttle.
4. Oil pressure “P” in the gear housing assembly includes only oil pressure occurred in “3R” and results in a
heavy steering force.

Item Function
Torque converterThe torque converter is the device that increases the engine torque as well as the con-
ventional AT and transmits it to the transaxle.
Oil pumpThe adoption of a trochoidal oil pump with a flow control valve actuated directly by the
engine enables the sufficient discharge from an oil pump in the low-rpm range and the
adequate discharge adjustments in the high-rpm range.
Planetary gear

ment. Forward clutch
Reverse brake
Primary pulley It is composed of a pair of pulleys (the groove width is changed freely in the axial direc-
tion) and the steel belt (the steel star wheels are placed continuously and the belt is guid-
ed with the multilayer steel rings on both sides). 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 pul-
ley. Secondary pulley

Item Function
Torque converterThe torque converter is the device that increases the engine torque as well as the conventional
CVT and transmits it to the transaxle.
Oil pumpThe efficiency of pump discharge rate has been increased at low-rpm and optimized at high-rpm
by adopting a vane-type oil pump controlled by the engine. Discharged oil from oil pump is trans-
mitted to the control valve. It is used as the oil of primary and secondary pulley operation and the
oil of clutch operation and the lubricant for each part.

ROAD WHEEL TIRE ASSEMBLY
 When installing balance weight (1) to road wheels, set it into
the grooved area (A) on the inner wall of the road wheel as
shown in the figure so that the balance weight center (B) is
aligned with the tire balance machine indication position
(angle) (C).
CAUTION:
 Always use genuine NISSAN adhesion balance weights.
 Balance weights are non-reusable; always replace with
new ones.
 Do not install more than three sheets of balance weight.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other as shown in
the figure.
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start the tire balance machine again.
4. Install drive-in balance weight on inner side of road wheel in the
tire balance machine indication position (angle).
CAUTION:
Do not install more than two balance weight.
5. Start the tire balance machine. Make sure that inner and outer
residual unbalance values are 5 g (0.17 oz) each or below.
6. If either residual unbalance value exceeds 5 g (0.17 oz), repeat installation procedures.
TIRE ROTATION
 Follow the maintenance schedule for tire rotation service intervals.
Refer to MA-5, "
General Maintenance".
 When installing the wheel, tighten wheel nuts to the specified
torque.
CAUTION:
 When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.
 Be careful not to tighten wheel nut at torque exceeding the
criteria for preventing strain of disc rotor.
 Use NISSAN genuine wheel nuts for aluminum wheels.
