PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS009A6
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 Man-
ual.
WA RN ING:

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.
PrecautionsEIS009A7

When removing or disassembling any part, be careful not to damage or deform it. Protect parts which may
get in the way with cloth.

When removing parts with a screwdriver or other tool, protect parts by wrapping them with vinyl or tape.

Keep removed parts protected with cloth.

If a clip is deformed or damaged, replace it.

If an unreusable part is removed, replace it with a new one.

Tighten bolts and nuts firmly to the specified torque.

After re-assembly has been completed, make sure each part functions correctly.

Remove stains in the following way.
–Water-soluble stains:
Dip a cloth in warm water, and squeeze tightly. After wiping the stain, wipe with a soft dry cloth.
–Oil stain:
Dissolve a synthetic detergent in warm water (density of 2 to 3% or less), dip the cloth, then clean off the
stain with the cloth. Next, dip the soft cloth in fresh water, and then squeeze it tightly. Then clean off the
detergent completely. Then wipe the area with a soft dry cloth.

Do not use any organic solvent, such as thinner or benzine.

When performing procedures that require removal of the cowl
top, cover the lower end of the windshield with a suitable protec-
tion material.

OIL PAN
2007 Versa
9. Insert a screwdriver shown by the arrow ( ) and open up a
crack between oil pan (upper) and cylinder block.
CAUTION:
A more adhesive liquid gasket is applied compared to previ-
ous types when shipped, so it should not be forced off the
position not specified.
10. After removing the bolts, separate the mating surface and
remove the sealant using Tool.

Slide (1) the Tool by tapping (2) its side with a hammer to
remove the lower oil pan from the upper oil pan.
CAUTION:
Be careful not to damage the mating surfaces.
11. Remove O-ring between cylinder block and oil pan (upper).
INSPECTION AFTER REMOVAL
Oil Filter
Clean oil strainer portion (part of the oil pump) if any object attached.

faces.

Remove the old liquid gasket from mating surface of cylinder
block.

Remove old liquid gasket from the bolt holes and threads.
