Install transaxle assembly to engine assembly with a hoist.

When installing fluid cooler tube to transaxle assembly, assem-
ble the part with the tube aligned with the rib.

When installing transaxle to the engine, attach the fixing bolts in
accordance with the following standard.

Align the positions of tightening nuts for drive plate with those of
the torque converter, and temporarily tighten the nuts. Then,
tighten the nuts with the specified torque.
CAUTION:

When turning crankshaft, turn it clockwise as viewed
from the front of the engine.

When tightening the tightening nuts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley
mounting bolts. Refer to EM-181, "
INSTALLATION" .

After converter is installed to drive plate, rotate crankshaft several turns and check to be sure
that transaxle rotates freely without binding.

Install crankshaft position sensor (POS). Refer to EM-145, "Removal and Installation" .

After completing installation, check for fluid leakage, fluid level, and the positions of CVT. Refer to CVT-13,
"Checking CVT Fluid" , CVT-178, "Adjustment of CVT Position" , CVT-179, "Checking of CVT Position" .

When replacing the CVT assembly, erase EEP ROM in TCM. Refer to CVT-9, "Precautions for TCM and
CVT Assembly Replacement" .

PRECAUTION PFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS001RV
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
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

COMBINATION METERSPFP:24814
System DescriptionBKS001RX
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter. Unified meter control unit receives signals 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 shift indicator segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination control

Unified meter control unit produces an illumination output of the
combination meter when the ignition switch is “ON”.

Light levels can be adjusted by pressing illumination control
switch of the combination meter when lighting switch is “ON”.

Illumination control switch has five light level settings.
NOTE:
When it is light outside, light level cannot be adjusted by turning
on the lighting switch.
UNIFIED METER AND A/C AMP.
Refer to DI-27, "System Description" in “UNIFIED METER AND A/C AMP”.
