Precautions for NATS
NATS (Nissan Anti-Theft System)
NATS will immobilize the engine if someone tries to start it with-
out the registered key of NATS.
All of the originally supplied ignition key IDs have been NATS
registered.
The NATS security indicator is located on the instrument panel.
The indicator blinks when the ignition switch is in ``OFF'' or
``ACC'' position. Therefore, NATS warns outsiders that the
vehicle is equipped with the anti-theft system.
lGasoline engine:
When NATS detects trouble, the malfunction indicator lamp
(MIL) blinks.
This blinking indicates that the anti-theft is not functioning, so
prompt service is required.
lDiesel engine:
When NATS detects trouble while engine is running or igni-
tion switch in ``ON'' position, the NATS security indicator
comes on.
This indicates that the anti-theft is not functioning, so prompt
service is required.
lWhen servicing NATS (trouble diagnoses, system initialisa-
tion and additional registration of other NATS ignition key
IDs), CONSULT hardware and CONSULT NATS software is
necessary.
Regarding the procedures of NATS initialisation and NATS
ignition key ID registration, refer to CONSULT operation
manual, NATS.
Therefore, CONSULT NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
lWhen servicing NATS (trouble diagnoses, system initialisa-
tion and additional registration of other NATS ignition key
IDs), it may be necessary to re-register original key identifi-
cation. Therefore, be sure to receive all keys from vehicle
owner.
A maximum of four key IDs can be registered into NATS.
General Precautions
lDo not operate the engine for an extended period of time
without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflam-
mable materials. Special care should be taken when han-
dling any inflammable or poisonous materials, such as
gasoline, refrigerant gas, etc. When working in a pit or other
enclosed area, be sure to properly ventilate the area before
working with hazardous materials.
Do not smoke while working on the vehicle.
