"AIR BAG" and "SEAT BELT PRE-TENSIONER" NFST0037 The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER" used along with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. The SRS system composition which is available to NISSAN MODEL A33 is as follows (The composition varies according to optional equipment. ): ¼ For a frontal collision The Supplemental Restraint System consists of driver air bag module (located in the center of the steering wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable. ¼ For a side collision The Supplemental Restraint System consists of front side air bag module (located in the outer side of front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision), wiring harness, warning lamp (one of components of air bags for a frontal collision). Information necessary to service the system safely is included in the RS section of this Service Manual. [. . . ] 19.

If the steering gear must be removed, set the front wheels in the straight-ahead direction. Do not rotate the steering column while the steering gear is removed. ¼ Remove the steering wheel before removing the steering lower joint to avoid damaging the SRS spiral cable. ¼ Detach tie-rod outer sockets from knuckle arms with Tool. Refer to FE-11, "Removal and Installation". Set a suitable transmission jack under transaxle. Remove center member and rear engine mounting. Refer to SU-12, "Removal and Installation". Remove steering gear assembly. GI MA EM LC EC FE CL SST858C MT ¼ ¼ Install pipe connector. Observe specified tightening torque when tightening high-pressure and low-pressure pipe connectors. Excessive tightening will damage threads of connector or O-ring. Connector tightening torque: 1 Low-pressure side 27 - 39 N·m (2. 8 - 4. 0 kg-m, 20 - 29 ft-lb) 2 High-pressure side 15 - 25 N·m (1. 5 - 2. 5 kg-m, 11 - 18 ft-lb) The O-ring in low-pressure pipe connector is larger than that in high-pressure connector. Take care to install the proper O-ring. AT AX SU BR SST859C ¼ RS BT HA ¼ Initially, tighten nut on tie-rod outer socket and knuckle arm to 29 to 39 N·m (3 to 4 kg-m, 22 to 29 ft-lb). Then tighten further to align nut groove with first pin hole so that cotter pin can be installed. CAUTION: Tightening torque must not exceed 49 N·m (5 kg-m, 36 ft-lb). SC EL IDX SST824A ST-17 POWER STEERING GEAR AND LINKAGE Removal and Installation (Cont'd) ¼ ¼ Before removing lower joint from gear, set gear in neutral (wheels in straight-ahead position). After removing lower joint, put matching mark on pinion shaft and pinion housing to record neutral position. To install, set left and right dust boots to equal deflection.
