The security indicator is located on the combi meter. 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.
When NATS detects trouble, the security indicator lamp lights
up while ignition switch is in “ON” position.
This lighting up indicates that the anti-theft is not functioning,
so prompt service is required.
When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs),
CONSULT-II hardware and CONSULT-II NATS software is
necessary.
Regarding the procedures of NATS initialization and NATS
ignition key ID registration, refer to CONSULT-II operation
manual, NATS.
Therefore, CONSULT-II NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs), it
may be necessary to re-register original key identification.
Therefore, be sure to receive all keys from vehicle owner. A
maximum of five key IDs can be registered into NATS.
When failing to start the engine first time using the key of
NATS, start as follows.
a) Leave the ignition key in “ON” position for approximately 5
seconds.
b) Turn ignition key to “OFF” or “LOCK” position and wait approxi-
mately 5 seconds.
c) Repeat step 1 and 2 again.
d) Restart the engine while keeping the key separate from any
others on key-chain.
SGI285
GENERAL PRECAUTIONSNJGI0001S03Do not operate the engine for an extended period of time
without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refrig-
erant gas, etc. When working in a pit or other enclosed area,
be sure to properly ventilate the area before working with haz-
ardous materials.
Do not smoke while working on the vehicle.
SGI231
Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before work-
ing on the vehicle.
These operations should be done on a level surface.
When removing a heavy component such as the engine or
transaxle, be careful not to lose your balance and drop them.
Also, do not allow them to strike adjacent parts, especially the
brake tubes and master cylinder.
