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 SR 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 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 the SR 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 har- ness connectors. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni- tion ON or engine running, DO NOT 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. Precautions for Suspension INFOID:0000000007208076 • 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. • The tightening surface must be kept free of oil/grease. • When jacking up the vehicle with a floor jack, never hang the jack on the suspension beam.

Revision: July 2011 2012 Versa Sedan WHEEL ALIGNMENT RSU-5 < PERIODIC MAINTENANCE > C D F G H I J K L M A B RSU N O P WHEEL ALIGNMENT Inspection INFOID:0000000007208079 DESCRIPTION CAUTION: • The adjustment mechanisms of camber and toe-in are not included. • If camber and toe-in is outside the standard, check front suspension parts for wear and damage. Replace suspect parts if a malfunction is detected. 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-45, " Tire Air Pressure". • Road wheels for runout. • Wheel bearing axial end play. Refer to RAX-9, " Inspection". • Shock absorber operation. • Each mounting point of axle and suspension for looseness and deformation. • Each of rear suspension beam and shock absorber for cracks, deformation, and other damage. • 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/Cali- bration Schedule. THE ALIGNMENT PROCESS IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-13, "Wheelarch Height". 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. 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 Compensation" 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 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. CAMBER • Measure camber of both right and left wheels with a suitable alignment gauge. • If camber is outside specified range, replace rear suspension beam. Refer to RSU-12, " Exploded View". Camber : Refer to RSU-13, " Wheel Alignment". Revision: July 2011 2012 Versa Sedan RSU-6 < PERIODIC MAINTENANCE > WHEEL ALIGNMENT TOE-IN Measure toe-in by the following procedure. WARNING: • Always perform the following procedure on a flat surface. • Check that no person is in front of vehicle before pushing it. 1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture). 2. Push vehicle straight ahead about 5 m (16 ft). 3. Put matching mark (A) on base line of the tread (rear side) of both tires at the same height of hub center. These are measur- ing points. 4. Measure distance (A) (rear side). 5. Push vehicle slowly ahead to rotate wheels 180 degrees (1/2 turn). NOTE: If the wheels rotates more than 180 degrees (1/2 turn), start this procedure again from the beginning. Do not push the vehicle backward. 6. Measure distance (B) (front side). • If toe-in is outside specified range, replace rear suspension beam. Refer to RSU-12, " Exploded View".
