PRECAUTIONS
Revision: 2006 August
2006 Murano
PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NGS0003A
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 must be per-
formed by an authorized NISSAN/INFINITI 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 SRS section.
●
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Steering System
NGS0003B
●
In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.
●
Observe the following precautions when disassembling.
–
Before disassembly, thoroughly clean the outside of the unit.
–
Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
–
For easier and proper assembly, place disassembled parts in order on a parts rack.
–
Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
–
Do not reuse non-reusable parts.
–
Before assembling, apply the specified grease to the directed parts.

POWER STEERING FLUID
Revision: 2006 August
2006 Murano
POWER STEERING FLUID
PFP:KLF20
Checking Fluid Level
NGS0003F
1.
Check fluid level with engine stopped.
2.
Make sure that fluid level is between MIN and MAX.
3.
Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
●
The fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.
●
Do not reuse drained power steering fluid.
●
Recommended fluid is Genuine Nissan PSF or equiva-
lent.
Checking Fluid Leakage
NGS0003G
1.
Check the lines for improper attachment and for leaks, cracks,
damage, loose connections, chafing or deterioration.
2.
Run engine until fluid temperature reaches 50 to 80
°
C (122 to
176
°
F) in reservoir tank. Keep engine speed idle.
3.
Turn steering wheel right-to-left several times.
4.
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. (There is the possibility that oil pump may
be damaged.)
5.
If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over tighten con-
nector as this can damage O-ring, washer and connector.
6.
If fluid leakage from oil pump is noticed, check oil pump. Refer to
.
7.
Check steering gear boots for accumulation of power steering fluid indicating a steering gear leak.
HOT
: Fluid temperature 50 - 80
°
C (122 - 176
°
F)
COLD
: Fluid temperature 0 - 30
°
C (32 - 86

Air Bleeding Hydraulic System
NGS0003H
1.
Turn steering wheel several times from full left stop to full right stop with engine off.
CAUTION:
●
Turn steering wheel while filling reservoir tank with fluid so as not to lower fluid level below the
MIN line.
●
When air bleeding is incomplete, the following phenomena occur. Although a fluid sound can be
heard from the gear and pump when turning the steering wheel all the way or slowly, this is not
a malfunction.
–
Bubbles are created in reservoir tank.
–
Clicking noise can be heard from power steering oil pump.
–
Excessive buzzing in the power steering oil pump.
2.
Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3.
Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that power steering oil pump may be damaged.)
4.
Check fluid for bubbles and while contamination.
5.
Stop engine if bubbles and white contamination do not drain out. Perform steps 2 and 3 above after wait-
ing until bubbles and white contamination drain out.
6.
Stop the engine, and then check fluid level.

steering wheel is not in the neutral position.
STEERING WHEEL TURNING FORCE
1.
Park vehicle on a level and dry surface, set parking brake.
2.
Tires need to be inflated normal pressure.
3.
Start engine.
4.
Bring power steering fluid up to adequate operating temperature. [Make sure temperature of fluid is
approximately 50 to 80
°
C (122 to 176
°
F).]
5.
Check steering wheel turning force when steering wheel has
been turned 540
°
from neutral position.
NOTE:
Multiply the distance (L) from the hook of spring scale to the
center of steering wheel by the measurement value with a spring
scale.
6.
Check the following items when steering wheel turning force is
more than the standard.
a.
Check relief oil pressure of power steering oil pump. Refer to
Steering wheel axial end play
: 0 mm (0 in)
Steering wheel play
: 0 - 35 mm (0 - 1.37 in)

PS-20, "Disassembly and Assembly"
.
FRONT WHEEL TURNING ANGLE
1.
FSU-5, "Wheel Alignment Inspection"
2.
Place front wheels on turning radius gauges and rear wheels on
stands so that vehicle can be level. Check the maximum inner
and outer wheel turning angles for LH and RH road wheels.
3.
Start engine and run at idle, turn steering wheel all the way right
and left, measure the turning angle.
4.
Check the following items when turning angle is out of the standard.
a.
Check rack stroke.
b.
Disassemble steering gear assembly to check the cause that
rack stroke is outside of the standard. Refer to
.
c.
Steering angles are not adjustable. Check steering gear assem-
bly, steering column assembly and front suspension compo-
nents for wear or damage if any of the turning angles are
different from the specified value. Replace any of them, if any
non-standard condition exists.
