HEATED STEERING WHEEL SYSTEM : System DescriptionINFOID:0000000009461247
The heated steering wheel switch c ontrols the heated steering relay through the A/C Auto amp. When the
switch is turned on, the relay is energized and t he heated steering system will operate. The heated steering
system will turn off when the steering w heel temperature reaches approximately 86 ° F (30 ° C). Heated steer-
ing system operation can also be canceled by pressing t he heated steering wheel switch again. If the surface
temperature of the steering wheel is below 68 ° F (20 ° C), the system will heat the steering wheel and cycle off
and on to maintain a temperature above 68 ° F (20 ° C). The indicator light will remain on as long as the system
is on.

POWER STEERING FLUID
InspectionINFOID:0000000009461251
FLUID LEVEL
Check power steering fluid level at the scale on reservoir tank cap
indicator.
• Check power steering fluid level with engine stopped and the fluid temp between 0 – 30 ° C (32 – 86 ° F).
• Power steering fluid level should be between the hatching area of the indicator on the power steering reservoir tank cap.
CAUTION:
• Do not overfill.
• Do not reuse used power steering fluid.
• Recommended power steering fluid is Genuine NISSAN E-
PSF or equivalent. Refer to MA-11, "FOR USA AND CANADA :
Fluids and Lubricants".
FLUID LEAKAGE
Check the power steering hydraulic system for leaks, cracks, dam-
age, loose connections, chafing or det erioration. Repair or replace
as necessary.
1. Start engine and allow engine to idle.
2. Turn steering wheel right-to-left several times.
3. Hold steering wheel at each “lock” position for five seconds to check fluid leakage.
CAUTION:
Do not hold steering wheel in a locked position for more
than 10 seconds. Damage to power steering oil pump may
occur.
4. If power steering fluid leakage at connections is noticed, loosen flare nut and retighten.
CAUTION:
Do not over tighten flare nut as damage to O-ring and connection can occur.
5. If power steering fluid leakage from the power steer ing oil pump is noticed, repair connection or replace
power steering oil pump. Refer to ST-15, "Inspection"
.
6. Check steering gear boots for accumulation of power st eering fluid. Power steering fluid indicates a leak
from the power steering gear, replace as necessary. Refer to ST-36, "Removal and Installation"
.

CONDITION OF INSTALLATION
• Check installation condition of power steering gear assembly, front suspension, front drive shaft and steering
column.
• Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
• Verify that the power steering gear nuts are tightened to specification. Refer to ST-36, "Exploded View"
.
STEERING WHEEL PLAY
1. Turn tires straight ahead, start engine, then turn steer ing wheel to the left and right lightly. Measure steer-
ing wheel movement on the outer circumference of the steering wheel when it is turned to the point where
tires start moving.
NEUTRAL POSITION ON STEERING WHEEL
• Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-
25, "Wheel Alignment (Unladen*1)".
1. Turn tires straight ahead, check if st eering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot be attained by repositi oning the steering wheel two teeth or less on steering
stem, loosen tie-rod lock nuts of power steering gear outer sockets, then adjust tie-rods by the same
amount in the opposite direction.
STEERING WHEEL TURNING FORCE
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to operating temperature.
4. Verify that the tires are inflated to the specified pressure. Refer to WT-60, "Tire"
.
5. Check steering wheel turning force using Tool when steering wheel has been turned 360 ° from the neutral position.
6. If steering wheel turning force is out of specification, inspect steering column. Refer to ST-18, "Inspection"
.
7. If steering column meets specification, inspect steering gear. Refer to ST-20, "Inspection"
.

• Check front wheel turning angle after toe-in inspection. Place front wheels on turning radius gauges and rear wheels on stands.
Check the maximum inner and outer wheel turning angles for LH
and RH road wheels.
• Measure the turning angles with the engine at idle, then turn the steering wheel from full left stop to full right stop and measure the
turning angle. Refer to ST-46, "Steering Angle"
.
• Measure the rack stroke specification with vehicle in neutral posi- tion. Refer to ST-20, "Inspection"
