Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
AKS00D4N
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.

COMBINATION METERS
Revision: 2005 August

COMBINATION METERS
PFP:24814
System Description
AKS00D4P
UNIFIED METER CONTROL UNIT
●
Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.
●
Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.
●
Digital meter is adopted for odo/trip meter.*
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
●
Odo/trip meter and CVT indicator segments can be checked in diagnosis mode.
●
Meters/gauges can be checked in diagnosis mode.
Illumination Control
The unified meter control unit outputs the odo/trip meter and CVT
indicator lighting when the ignition switch is turned on. When the
lighting switch is turned on, light on for the combination meter dial,
odo/trip meter and illumination control switch and external lighting
are output. In addition, when the lighting switch is turned on, the illu-
mination control switch on the left side of the combination meter can
be used to adjust the brightness of each light. The brightness can be
adjusted to sixteen different levels: From 0 (no lights) to 15 (maxi-
mum). Pressing the illumination control switch will brighten or darken
the lights. When the key switch is in the START position, the combi-
nation meter dial lighting and illumination control switch lighting are
turned off.
