System Description
INFOID:0000000005260161
The heated steering wheel switch controls the heated steering relay. When the switch is turned on, the relay is
energized and the heated steering system will operate. The heated steering system will turn off when the
steering wheel temperature reaches approximately 86
°
F (30
°
C). Heated steering system operation can also
be canceled by pressing the heated steering wheel switch again.
NOTE:
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. Push the switch again to turn the heated steering wheel system off instructionly. The indica-
tor light will go off.

POWER STEERING FLUID
Checking Fluid Level
INFOID:0000000005260166
Check fluid level, referring to the scale on the reservoir tank.
Use HOT range for fluid temperatures of 50
°
– 80
°
C (122
°
– 176
°
F).
Use COLD range for fluid temperatures of 0
°
– 30
°
C (32
°
– 86
°
F).
CAUTION:
• Do not overfill.
• Do not reuse any power steering fluid.
• Recommended fluid is Genuine NISSAN PSF or equivalent.
Refer to
.
Checking Fluid Leakage
INFOID:0000000005260167
Check the hydraulic piping lines for improper attachment, leaks,
cracks, damage, loose connections, chafing and deterioration.
1. Run the engine until the fluid temperature reaches 50
°
– 80
°
C
(122
°
– 176
°
F) in the reservoir tank. Keep engine speed idle.
CAUTION:
Do not allow steering fluid reservoir tank to go below the
MIN level line. Check tank frequently and add fluid as
needed.
2. Turn the steering wheel to the right and left several times.
3. Hold the steering wheel at each “locked” position for five sec-
onds to check for fluid leakage.
CAUTION:
Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibil-
ity that the oil pump may be damaged.)
4. If fluid leakage at a connection is noticed, loosen the connection and then retighten. Do not over-tighten
connector as this can damage O-ring, washer and connector. Refer to
.
5. If fluid leakage from the oil pump is noticed, check the oil pump. Refer to
6. Check steering gear boots for accumulation of fluid, indicating a leak from the steering gear.
CAUTION:
Do not reuse copper washers.
Air Bleeding Hydraulic System
INFOID:0000000005260168
Incomplete air bleeding causes the following:
• Air bubbles in reservoir tank
• Clicking noise in oil pump
• Excessive buzzing in oil pump
When this happens bleed the air again.
NOTE:
When the vehicle is stationary or while the steering wheel is being turned slowly, some noise may be heard
from the oil pump or gear. This noise is normal and does not affect any system.
1. Check for fluid leakage. Refer to
ST-13, "Checking Fluid Leakage"
2. Start the engine and turn the steering wheel fully to the right and left several times.
CAUTION:
Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and
add fluid as needed.
3. Run the engine at idle speed. Hold the steering wheel at each "locked" position for three seconds.
CAUTION:
