6. Repeat steps above as necessary to check the other seat belts.
SEAT BELT RETRACTOR ON-VEHICLE CHECK
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop)
the retractor will lock and prevent the webbing from extending any further. All 3-point type seat belt retractors
except the driver's seat belt also have an Automatic Locking Retractors (ALR) mode. The ALR mode (also
called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt
is fully extended. When the webbing is then retracted partially, the ALR mode automatically locks the seat belt
in a specific position so the webbing cannot be extended any further. To cancel the ALR mode, allow the seat
belt to fully wind back into the retractor.
Check the seat belt retractors using the following test(s) to determine if a retractor assembly is operating prop-
erly.
ELR Function Stationary Check
Grasp the shoulder webbing and pull it forward quickly. The retractor should lock and prevent the belt from
extending further.
ALR Function Stationary Check
1. Pull out entire length of seat belt from retractor until a click is heard.
2. Retract the webbing partially. A clicking noise should be heard as the webbing retracts, indicating that the
retractor is in the Automatic Locking Retractors (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If
NG, replace the retractor assembly.
4. Allow the entire length of the webbing to retract to cancel the automatic locking mode.
ELR Function Moving Check
WARNING:
Perform the following test in a safe, open area clear of other vehicles and obstructions (for example, a
large, empty parking lot). Road surface must be paved and dry. DO NOT perform the following test on
wet or gravel roads or on public streets and highways. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event the
retractor does not lock.
1. Fasten driver's seat belt. Buckle a passenger into the seat for the belt that is to be tested.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop
and the driver and passenger must be prepared to brace themselves in the event the retractor does not
lock, apply brakes firmly and make a very hard stop.
During the stop, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock,
perform the retractor off-vehicle check.
SEAT BELT RETRACTOR OFF-VEHICLE CHECK
1. Remove the seat belt retractor. Refer to SB-6, "Removal and Installation of Front Seat Belt".

 Intelligent Key has 2 IDs (for Intelligent Key and for NATS). It can perform the door lock/unlock operation and
the engine start operation when the registered Intelligent Key is carried.
 When the Intelligent Key battery is discharged, it can be used as emergency back-up by inserting the
mechanical key set in the Intelligent Key to the ignition key cylinder. At that time, perform the NATS ID verifi-
cation. If it is used when the Intelligent Key is carried, perform the Intelligent Key ID verification.
 If the ID is successfully verified, and when the ignition knob switch is pressed, steering lock will be released
and initiating the engine will be possible.
 The door lock/unlock operation can be performed when the Intelligent Key battery is discharged, by operat-
ing the driver door key cylinder using the mechanical key set in the Intelligent Key.
 Up to 4 Intelligent Keys can be registered (including the standard Intelligent Key) on request from the owner.
NOTE:
 Refer to XX-XX, "*****"
for any functions other than engine start function of Intelligent Key system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
In the Intelligent Key system, the transponder [the chip for NATS ID verification] is integrated into the
Intelligent Key. (For non-Intelligent Key systems, it is integrated into the mechanical key.) Therefore,
the mechanical key cannot perform the ID verification, and thus it cannot start the engine. Instead,
the NATS ID verification can be performed by inserting the mechanical key into the key cylinder, and
then it can start the engine.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the ignition knob switch and brake switch are ON, and Intelligent Key unit is transmitting the request
signal to the Intelligent Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the Intelligent
Key unit.
3. The Intelligent Key unit receives the Intelligent Key ID signal and verifies it with the registered ID.
4. Intelligent Key unit transmits the steering lock unlock signal to steering lock unit and turn on the key warn-
ing lamp (green) if the verification results are OK. (The detail of key warning lamp operation, refer to XX-
XX, "*****")
5. Release of the steering lock.
6. BCM transmits the starter request signal via CAN communication to IPDM E/R and turns the starter relay
in IPDM E/R ON if BCM judges that the engine start condition is satisfied.
7. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
8. When shift position is in P or N position, battery power is supplied through the starter relay and operate
the starter motor and to start the cranking.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning lamp in the combina-
tion meter illuminates. At that time, the engine cannot be started.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine might not start
when Intelligent Key is on instrument panel or in glove box.
OPERATION WHEN MECHANICAL KEY IS USED
When the Intelligent Key battery is discharged, performs the NATS ID verification between the integrated tran-
sponder and BCM by inserting the mechanical key into the key cylinder, and then the engine can be started.
For details relating to starting the engine using mechanical key, refer to SEC-12, "
System Description".
STEERING LOCK OPERATION
Steering is locked by steering lock unit when ignition switch is in the OFF position (the ignition knob is
released) and key switch is OFF (key is removed from ignition key cylinder).
KEY INTERLOCK OPERATION (ONLY FOR M/T MODELS)
In case of a M/T vehicle is in motion and ignition is turned into LOCK position, steering lock unit causes a risk
by activating the steering lock actuator. The key interlock operation is designed to override the steering lock
system and prevent the situation mentioned above from occuring.
LOCK condition
When the following conditions are fulfilled, key interlock solenoid will be locked. (Steering lock inactive)
 1 second passes after ignition switch is in ON position and engine revolution speed goes above 500 rpm.
