3. Install side flange with the following procedure.
a. Attach the protector to side oil seal.
b. After the side flange is inserted and the serrated part of side
gear has engaged the serrated part of flange, remove the pro-
tector.
c. Put a suitable drift on the center of side flange, then drive it until
sound changes.
NOTE:
When installation is completed, driving sound of the side flange
turns into a sound which seems to affect the whole final drive.
d. Confirm that the dimension of the side flange installation (Mea-
surement A) in the figure comes into the following.
4. Install drive shaft. Refer to RAX-8, "
REAR DRIVE SHAFT" .
5. Install rear wheel sensor. Refer to BRC-57, "

.
6. Install center muffler. Refer to EX-3, "

AUTOMATIC DRIVE POSITIONER
Revision: 2006 January2006 M35/M45
System DescriptionNIS0025R
The system automatically moves the driver seat, steering and door mirror position by the driver seat con-
trol unit and the automatic drive positioner control unit. The driver seat control unit corresponds with the
automatic drive positioner control unit via UART communication. The driver seat control unit can store the
optimum driving positions (driver seat, steering and door mirror position) for 2 people. If the driver
changes, one-touch operation allows changing to the other driving position.
The driver seat, steering and door mirror position are adjusted automatically to the proper positions for the
driver in different ways: MEMORY OPERATION, EXITING OPERATION, ENTRY OPERATION and
INTELLIGENT KEY INTERLOCK OPERATION.
MANUAL OPERATION
The driving position (seat, steering and door mirror position) can be adjusted with the power seat switch, ADP
steering switch and door mirror control switch.
NOTE:
The door mirrors can be manually operated with the ignition switch in either ACC or ON.
MEMORY OPERATION
The driver seat control unit can store the optimum driving positions (seat, steering and door mirror position) for
2 people. If the front seat position is changed, one-touch (pressing desired memory switch for more than 0.5
second) operation allows changing to the other driving position.
Operation procedure
1. Turn ignition switch ON.
2. Press desired memory switch for 0.5 second. (Indicator LED illuminates.)
3. Driver seat, steering and door mirror will move to the memorized position.
(Indicator LED blinks during adjustment, then illuminates for 5 seconds.)
Operation Condition
If the following conditions are not satisfied, memory switch operation is not performed.
Ignition switch is in ON position.
Driver side power seat switch, ADP steering switch and door mirror control switch are not operated.
Seat memory switch and set switch are not operated.
Output malfunction is not detected.
CAN and UART communications are normal.
A/T selector lever position is in P position.
Detention switch malfunction is not detected.
[Detention switch malfunction is sensed when detention switch remains OFF, vehicle speed is higher than
7 km/H. (4 MPH).]
Input voltage from tilt sensor and telescopic sensor are normal.
NOTE:
The memory operation operates following order.
Function Description
Manual operationThe driving position (seat, steering and door mirror position) can be adjusted with
the power seat switch ADP steering switch or door mirror control switch.
Auto-
matic
operationMemory operation The seat, steering and door mirror move to the stored driving position by pushing
seat memory switch (1 or 2).
Entry/
Exiting
functionExiting operation At exit, the seat moves backward and the steering wheel moves upward.
Entry operationAt entry, the seat and steering wheel returns from exiting position to the previous
driving position before the exiting operation.
Intelligent Key interlock operationPerform memory operation, exiting operation and entry operation by pressing Intel-
ligent Key unlock button.

SETTING CHANGE FUNCTION
The settings of the automatic driving positioner system can be changed, using CONSULT-II and the display
unit in the center of the instrument panel.
: Applicable –: Not applicable
It is possible to set sliding driver seat for entry/exit of vehicle by pressing set switch.
CAN Communication System DescriptionNIS0025S
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitNIS0025T

AWD SYSTEM
Revision: 2006 January2006 M35/M45
AWD SYSTEMPFP:41650
Power Transfer DiagramNDS000DB
System DescriptionNDS000DC
DESCRIPTION
Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close
to rear-wheel drive.
Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
NOTE:
When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too high and AWD warning lamp flashes rapidly.
(When AWD warning lamp flashes, vehicle changes to rear-wheel drive conditions.) Also, optional distri-
bution of torque sometimes becomes rigid before lamp flashes rapidly, but it is not malfunction.
If AWD warning lamp is flashing rapidly, stop vehicle and allow it to idle for some time. Flashing will stop
and AWD system will be restored.
When driving, AWD warning lamp may flash slowly if there is a significant difference in diameter of the
tires. At this time, vehicle performance is not fully available and cautious driving is required. (Continues
until engine is turned OFF.)
If the warning lamp flashes slowly during driving but remains OFF after engine is restarted, the system is
normal. If it again flashes slowly after driving for some time, vehicle must be inspected.
When the difference of revolution speed between the front and rear wheel the shift occasionally changes
to direct 4-wheel driving conditions automatically. This is not malfunction.
