PRECAUTIONS
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRETENSIONER”

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 Manual.

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 Rear Suspension
When installing the rubber bushings, the final tightening must be done under unladen condition and with the tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immediately.
Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The spare tire, jack, hand tools, and mats are in their designated positions.
After installing suspension components, check the wheel alignment.
Caulking nuts are not reusable. Always use new caulking nuts for installation. New caulking nuts are preoiled, do not apply any additional lubrication.

Possible cause and SUSPECTED PARTS

REAR SUSPENSION ASSEMBLY
On-Vehicle Inspection and Service
Make sure the mounting conditions (looseness, backlash) of each component and component conditions (wear, damage) are within specifications.

SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace it if necessary.

Wheel Alignment Inspection
DESCRIPTION
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 the following:
1.Tires for improper air pressure and wear.
2.Road wheels for runout. Refer to WT-5, “ROAD WHEEL” .
3.Wheel bearing axial end play. Refer to RAX-4, “REAR WHEEL BEARING INSPECTION” .
4.Shock absorber operation.
5.Each mounting part of suspension for looseness and deformation.
6.Rear suspension beam for cracks, deformation, and other damage.
7.Vehicle height (posture).

GENERAL INFORMATION AND RECOMMENDATIONS
1.A Four-Wheel Thrust Alignment should be performed.
This type of alignment is recommended for any NISSAN vehicle.
The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel is centered.
The alignment machine itself should be capable of accepting any NISSAN vehicle.
The alignment machine should be checked to ensure that it is level.
2.Make sure the alignment machine is properly calibrated.
Your alignment machine should be regularly calibrated in order to give correct information.
Check with the manufacturer of your specific alignment machine for their recommended Service/Calibration Schedule.

THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-13, “Wheel
Alignment (Unladen*)” .
1.When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Do NOT use these indicators.
The alignment specifications programmed into your alignment machine that operate these indicators may not be correct.
This may result in an ERROR.
2.Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com- pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation” method.
Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the vehicle and rotate the wheels 1/2 turn both ways.
See Instructions in the alignment machine you are using for more information.

REAR SUSPENSION ASSEMBLY

CAMBER INSPECTION
Measure camber of both right and left wheels with a suitable alignment gauge.
Camber: Refer to RSU-13, “Wheel Alignment (Unladen*)”.
If it is out of the specification value, inspect and replace any damaged or worn rear suspension parts.

REAR SUSPENSION ASSEMBLY

TOE-IN INSPECTION
Measure toe-in using following procedure. If it is out of the specification, inspect and replace any damaged or worn rear suspension parts.
WARNING:
Always perform the following procedure on a flat surface.
Make sure that no person is in front of vehicle before pushing it.
1.Bounce the rear of vehicle up and down to stabilize the vehicle height (posture).
2.Push vehicle straight ahead about 5 m (16ft).
3.Put a mark on base line of the tread (rear side) of both tires at the same height of hub center. These are measuring points.
nissan versa tiida rear suspension - ManualesAutomotricesWeb.com
4.Measure distance “A” (rear side).
5.Push vehicle slowly ahead to rotate wheels 180 degrees (1/2 turn). If wheels have rotated more than 180 degrees (1/2 turn), try the above procedure again from the beginning. Never push vehicle backward.
6.Measure distance “B” (front side).
Total toe-in: Refer to RSU-13, “Wheel Alignment (Unladen*)”.
