PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001094854
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 SRC 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 SRC 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.

LEVEL
• Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
• Adjust the engine coolant level as necessary.
• Check that the reservoir tank cap is tightened.
WARNING:
Never remove reservoir tank cap when engine is hot. Serious
burns could occur from high-pressure engine coolant escaping
from reservoir tank.
LEAKAGE
• To check for leakage, fit the adapter to the reservoir tank, and then
connect it to the reservoir tank cap tester [SST: — (M.S.554-07)]
(A) as shown.
WARNING:
Never remove reservoir tank cap when engine is hot. Serious
burns could occur from high-pressure engine coolant escap-
ing from reservoir tank.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
• If anything is found, repair or replace damaged parts.
Draining
INFOID:0000000000905144
WARNING:
• Never remove reservoir tank cap when engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from reservoir tank.
• Wrap a thick cloth around the reservoir tank cap. Slowly turn it a quarter of a turn to release built-up
pressure. Then turn it all the way.
1.
Disconnect radiator hose (lower) and reservoir tank cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to
.
CAUTION:
• Perform this step when engine is cold.
• Never spill engine coolant on drive belt.
2.
Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
• Remove of engine mounting insulator (RH) is necessary. Refer to
(CVT models).
3.
Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to
CO-33, "RADIATOR : Inspection"
.
Refilling
INFOID:0000000000905145
1.
Install reservoir tank if removed.
2.
Connect radiator hose (lower).
If water drain plugs on cylinder block are removed, close and tighten them. Refer to
.
