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.

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 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.

CVT Fluid Cooler Cleaning

ACS004MD

Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the CVT fluid cooler. This debris can con-
taminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid. In either case,
malfunction of the newly serviced CVT may result.
Debris, if present, may build up as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.

CVT FLUID COOLER CLEANING PROCEDURE

Position an oil pan under the transaxle's inlet and outlet cooler hoses.

Identify the inlet and outlet fluid cooler hoses.

Disconnect the fluid cooler inlet and outlet rubber hoses from the
steel cooler tubes or bypass valve.

NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.

Allow any CVT fluid that remains in the cooler hoses to drain into
the oil pan.
