PRECAUTIONSPFP:00001
DescriptionEAS001GG
Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EAS001GH
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for NATS (NISSAN ANTI-THEFT SYSTEM)EAS001GI
NATS will immobilize the engine if someone tries to start it without the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS registered.
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NATS warns outsiders that the vehicle is equipped with the anti-theft system.
lWhen 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.
lWhen 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 con-
fidential to maintain the integrity of the anti-theft function.
lWhen 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 four or five key IDs can be registered into NATS.
lWhen failing to start the engine first time using the key of NATS, start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.
Precautions Necessary for Steering Wheel Rotation After Battery DisconnectEAS001HY
NOTE:
lThis Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).
lRemove and install all control units after disconnecting both battery cables with the ignition knob in the
²LOCK²position.
lAlways use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.

lCONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.

WARNING:
lNever get under the vehicle while it is supported only by the jack. Always use safety stands to
support the frame when you have to get under the vehicle.
lPlace wheel chocks at both front and back of the wheels on the ground.
CAUTION:
lAll applicable local laws regarding the towing operation must be obeyed.
lIt is necessary to use proper towing equipment to avoid possible damage during towing opera-
tion. Towing is in accordance with Towing Procedure Manual at dealer.
lAlways attach safety chains before towing.
lWhen towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.
lNever tow an automatic transmission model from the rear
(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.
4X2 MODEL
NISSAN does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
lWhen towing with the front wheels on the ground: Turn the
ignition key to the OFF position and move the transmission
selector lever to N (neutral) position, turn the ignition key to
OFF position and secure the steering wheel in a straight
ahead position with a rope or similar device. Never place
the ignition key in the LOCK position. This will result in
damage to the steering lock mechanism.
Observe the following restricted towing speeds and distances.

4X4 MODEL
NISSAN does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.
CAUTION:
lWhen towing with the front wheels on the ground or rear
wheels on the ground (If you do not use towing dollies):
Set the free-running hubs to the free position and move the
transfer case shift lever into the “2H” position.
lWhen towing with the front on the ground: Turn the ignition
key to the OFF position and secure the steering wheel in a
straight ahead position with a rope or similar device. Never
place the ignition key in the LOCK position. This will result
in damage to the steering lock mechanism.
Observe the following restricted towing speeds and distances.
TOWING POINT
CAUTION:
Never tow the vehicle using only the towing points. To avoid
damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a Stuck Vehicle)EAS001DJ
lTow chains or cables must be attached only to the main structural members of the vehicle.
lPulling devices should be routed so they do not touch any part of the suspension, steering, brake
or cooling systems
lAlways pull the cable straight out from the front or rear of the vehicle. Never pull the vehicle at a
sideways angle.
lPulling devices such as ropes or canvas straps are not recommended for use for vehicle towing or
recovery.Speed : Below 50 km/h (30 MPH)
Distance : Less than 65 km (40 miles)
