Murano Cross Cabriolet Z51 (2013 year). Manual - part 38

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric 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 3 minutes before performing any service.

Precaution for Battery Service

INFOID:0000000008461644

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000008461645

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precautions for Suspension

INFOID:0000000008461646

• When installing rubber bushings, the final tightening must be carried out under unladen conditions with tires

on ground. Spilled oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.

- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and

mats are in designated positions.

• After servicing suspension parts, be sure to check wheel alignment.
• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-oiled,

tighten as they are.

Inspection

INFOID:0000000008461650

COMPONENT PART

Check the mounting conditions (looseness, backlash) of each component and component conditions (wear,
damage) are normal.

Ball Joint Axial End Play

Set front wheels in a straight-ahead position.

Move axle side of transverse link in the axial direction by hand.
Check there is no end play.

CAUTION:

• Never depress brake pedal when measuring.
• Never perform with tires on level ground.
• Be careful not to damage ball joint boot. Never damage

the installation position by applying excessive force.

STRUT ASSEMBLY

Check for oil leakage and damage. Replace if necessary.

WHEEL ALIGNMENT

Inspection

INFOID:0000000008461651

DESCRIPTION

CAUTION:

• Camber, caster, kingpin inclination angles cannot be adjusted.
• If camber, caster, or kingpin inclination angle is outside the standard, check front suspension parts

for wear and damage. Replace suspect parts if a malfunction is detected.

• Kingpin inclination angle is reference value, no inspection is required.
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.

PRELIMINARY CHECK

Check the following:
• Tires for improper air pressure and wear. Refer to

WT-50, "Tire Air Pressure"

• Road wheels for runout.
• Wheel bearing axial end play. Refer to

FAX-6, "Inspection"

• Transverse link ball joint axial end play. Refer to

FSU-6, "Inspection"

• Strut operation.
• Each mounting part of axle and suspension for looseness and deformation.
• Each of suspension member, shock absorber, upper link and transverse link for cracks, deformation and

other damage.

• Vehicle height (posture).

GENERAL INFORMATION AND RECOMMENDATIONS

• A four-wheel thrust alignment should be performed.
- This type of alignment is recommended for any NISSAN/INFINITI vehicle.
- The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is

centered.

- The alignment rack itself should be capable of accepting any NISSAN/INFINITI vehicle.
- The rack should be checked to ensure that it is level.
• Make sure the machine is properly calibrated.
- Your alignment equipment should be regularly calibrated in order to give correct information.
- Check with the manufacturer of your specific equipment for their recommended Service/Calibration Sched-

ule.

ALIGNMENT PROCESS

IMPORTANT:
Use only the alignment specifications listed in this Service Manual.
• When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or

minus, Go/No Go). Never use these indicators.

- The alignment specifications programmed into your machine that operate these indicators may not be cor-

rect.

- This may result in an ERROR.
• Most camera-type alignment machines are equipped with both “Rolling Compensation” method and optional

“Jacking Compensation” method to “compensate” the alignment targets or head units. “Rolling Compensa-
tion” is the preferred method.

- If using the “Rolling Compensation” method, after installing the alignment targets or head units, push or pull

on the rear wheel to move the vehicle. Do not push or pull on the vehicle body.

- If using the “Jacking Compensation” method, after installing the alignment targets or head units, raise the

vehicle and rotate the wheels 1/2 turn both ways.
NOTE:
Do not use the “Rolling Compensation” method if you are using sensor-type alignment equipment.

- Follow all instructions for the alignment machine you're using for more information.
