Fuse EKS00BNG
If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.
Use fuse of specified rating. Never use fuse of more than speci-
fied rating.
Do not partially install fuse; always insert it into fuse holder prop-
erly.
Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible Link EKS00BNH
A melted fusible link can be detected either by visual inspection or by feeling with finger tip. If its condition is
questionable, use circuit tester or test lamp.
CAUTION:
If fusible link should melt, it is possible that critical circuit (power supply or large current carrying
circuit) is shorted. In such a case, carefully check and eliminate cause of incident.
Never wrap outside of fusible link with vinyl tape.
Never let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00BNI
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:
Power seat
Power windows
Power door locks
Remote keyless entry system
Power sunroof
Rear window wiper

1. Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2. Visually inspect the battery, battery terminals and cable ends
with ignition switch in “OFF” position.
NOTE:
The contact surface between the battery terminals, cable ends
and tester leads must be clean for a valid test. A poor connec-
tion will prevent testing and a “CHECK CONNECTION” mes-
sage will appear during the test procedures. If this occurs, clean
the battery post and terminals, reconnect them and restart the
test.
3. Connect the red tester lead clamp to the positive battery termi-
nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys,
select “IN-VEHICLE” on the tester and then press the “ENTER”
key.
5. Locate the battery type and rating stamped or written on the top
case of the battery to be tested.
NOTE:
The battery rating will be either of the following:
CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.)
JIS: Japanese Industrial Standard.
When using the Battery Tester use the CCA rating only.
The tester requires the CCA rating for the battery be entered
exactly as it is written or stamped on the battery.
(U.S. market) Refer to the latest "Battery Testing" Technical
Service Bulletin (TSB) for a chart which contains these ratings
listed by vehicle.
You must not use the JIS rating.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE:
The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Only use CCA or JIS.
7. Press “ENTER” to begin the test. Diagnosis results are dis-
played on the tester. Refer to SC-8, "
DIAGNOSTIC RESULT
ITEM CHART" .

AUTOMATIC DRIVE POSITIONER
Revision: October 20052005 QX56
Manual OperationEIS004XC
The driving position [seat position, steering wheel, pedal position (accelerator, brake) and door mirror position]
can be adjusted with the power seat switch LH, pedal adjusting switch, door mirror remote control switch or
ADP steering switch.
NOTE:
The door mirrors can be manually operated with the ignition switch turned to ACC or ON.
Adjustable pedals can only operate when A/T shift lever is in P position (except when ignition switch
turned to OFF).
If A/T device (detent switch) error is detected, manual adjustable pedal operation cannot be performed
when ignition switch turns ON.
Automatic OperationEIS004XD
NOTE:
Disconnecting the battery erases the stored memory.
After connecting the battery, insert the key into the ignition cylinder and turn the front door switch LH ON (open)→OFF (close)→ON
(open), the Entry/ Exiting function becomes possible.
After Exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON→START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
System DescriptionEIS004XE
The system automatically moves the driver seat and steering wheel to facilitate entry/exit to/from the vehi-
cle. The driver seat control unit can also store the optimum driving positions (driver seat, steering wheel,
pedal position and door mirror position) for 2 people. One-touch operation allows changing between driv-
ing positions.

Function Description
Memory operation The seat, steering wheel, pedals (accelerator, brake) and door mirrors move to the
stored driving position by pushing seat memory switch (1 or 2).
Entry/Exit-
ing functionExiting operation At exit, the seat moves backward and the steering wheel raises. (Exiting position)
Entry operationAt entry, the seat and steering wheel return from Exiting position to the previous driv-
ing position before the Exiting operation.
Keyfob interlock operationPerform memory operation, turnout operation and return operation by pressing key-
fob unlock button.
Auto operation temporary stop
conditions.When ignition switch is turned to START during seat memory switch operation and return
operation, seat memory switch operation and return operation is stopped.
Auto operation stop conditions.
When the vehicle speed becomes 7 km/h (4 MPH) or higher (memory switch operation
and entry operation).
When the setting switch, seat memory switch 1, or 2 are pressed.
When A/T shift lever is in any position other than P.
When the door mirror remote control switch is operated (when ignition switch turned to
ON).
When power seat switch turned ON.
When pedal adjusting switch turned ON.
When front seat sliding Entry/Exiting setting is OFF (entry/exiting operation).

MEMORY STORING AND KEYFOB INTERLOCK STORING
Store the 2 driving positions and shifts to the stored driving position with the memory switch.
Keyfob interlock function is set simultaneously with setting driving position memory. It can set driving posi-
tion to memory position.
NOTE:
If another keyfob interlock function setting is performed by same key, the newly registered setting is valid.
If a new memory string is performed to memory switch that already set keyfob interlock function, keyfob
interlock function setting is reset.
If the keyfob has not been previously programmed to the vehicle, keyfob interlock function cannot set.

KEYFOB INTERLOCK OPERATION
The system performs memory operation, exiting operation and return operation by pressing keyfob unlock
button.
NOTE:
If Entry/Exiting operation is cancelled, the system performs memory operation only.
If ignition switch turns ON in the middle of memory operation, the system does not perform exiting opera-
tion after memory operation.
If ignition switch turns ON in the middle of exiting operation, entry operation starts at that time.
