6. Before servicing the vehicle, protect fenders, upholstery andcarpeting with appropriate covers.
Take caution that keys, buckles or buttons on your person do
not scratch the paint.
7. Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
8. Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
9. Replace inner and outer races of tapered roller bearings and needle bearings as a set.
10. Arrange the disassembled parts in accordance with their assembled locations and sequence.
11. Do not touch the terminals of electrical components which use microcomputers (such as electronic control units).
Static electricity may damage internal electronic components.
12. After disconnecting vacuum or air hoses, attach a tag to indi- cate the proper connection.
13. Use only the lubricants specified in MA section.
14. Use approved bonding agent, sealants or their equivalents when required.
15. Use tools and recommended special tools where specified for safe and efficient service repairs.
16. When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
17. Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.
Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
(Dual Air Bag System)
The Supplemental Restraint System ªAir Bagº and ªSeat Belt Pre-
tensionerº, used along with a seat belt, help to reduce the risk or
severity of injury to the driver and front passenger in a frontal col-
lision. The Supplemental Restraint System consists of air bag mod-
ules (located in the center of the steering wheel and on the instru-
ment panel on the passenger side), seat belt pre-tensioners, a
diagnosis sensor unit, warning lamp, wiring harness and spiral
cable.
WARNING:
ITo 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
dealer.
I Improper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury caused
by unintentional activation of the system.
I Do not use electrical test equipment on any circuit related
to the SRS unless instructed to do so in this Service
Manual. SRS wiring harnesses are covered with yellow
