Precautions for NATS
NATS (Nissan Anti-Theft System)
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 NATS security indicator is located on the instrument panel. The
indicator blinks when the ignition switch is in ªOFFº or ªACCº posi-
tion. Therefore, NATS warns outsiders that the vehicle is equipped
with the anti-theft system.
IWhen NATS detects trouble, the malfunction indicator lamp
(MIL) blinks.
This blinking indicates that the anti-theft is not functioning, so
prompt service is required.
I If the malfunction indicator lamp comes on while the engine is
running, return the vehicle to the workshop before turning the
ignition switch ªOFFº.
Once the ignition switch is turned ªOFFº, the engine can not be
started.
I When servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs) CON-
SULT-II hardware and CONSULT-II NATS software is neces-
sary.
Regarding the procedures of NATS initialization and NATS igni-
tion 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.
I 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.
I When failing to start the engine first-time using the key of
NATS, starts as follows:
(1) Turn ignition key to ªOFFº.
(2) Wait approx. 5 seconds.
(3) Turn ignition key to ªSTARTº again while keeping the key
apart from any others on key-chain.

Nickel Metal Hydride Battery Replacement
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with genuine CONSULT-II battery only. Use of another battery
may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if mis-
treated. Do not recharge, disassemble of dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.

4-pole Lift
WARNING:
Do not use a 2-pole lift.
Due to weight balance of the vehicle and shape of underbody,
lift arms can not be attached in a safe way. Therefore it is rec-
ommended to use a 4-pole lift only.
Tow Truck Towing
CAUTION:
IAll applicable local laws regarding the towing operation
must be obeyed.
I It is necessary to use proper towing equipment to avoid
possible damage to the vehicle during a towing operation.
I Attach safety chains for all towing.
I When towing, make sure that the transmission, steering
system and power train are in good order. If any unit is
damaged, a dolly must be used.
I When towing with the front wheels on the ground:
Move both the gearshift and transfer levers to neutral (ªNº
position).
Turn the ignition key to the ªOFFº position and secure the
steering wheel in a straightahead position with a rope or
similar device. Never place the ignition key in the ªLOCKº
position. This will result in damage to the steering lock
mechanism.
I When towing with the rear wheels on the ground, release
the parking brake and move both the gearshift and trans-
fer levers to neutral (ªNº position).
I Never tow vehicle from the rear (i.e., backward) with four
wheels on the ground as this may cause serious and
expensive damage to the transmission.

NISSAN recommends that a dolly be used as illustrated when tow-
ing 4-wheel drive models.
Towing with four wheels on ground or towing with front
(rear wheels on ground) or rear wheels (front wheels
on ground) raised
Observe the following restricted towing speeds and distances.Speed:Below 50 km/h (30 MPH)
Distance: Less than 65 km (40 miles)
If the speed or distance must necessarily be greater, remove the
front and rear propeller shafts beforehand to prevent damage to the
transmission.
TOWING POINT
I Always pull the cable straight out from the vehicle. Never
pull on the hook at a sideways angle.
I Use proper towing equipment when towing. Otherwise, the
vehicle body will be damaged.
Front
I Only R.H. hook may be used for towing purposes. Use L.H.
hook only for securing the vehicle during transportation.
Rear
I Either hook can be used for towing purposes.
A platform should be used.

Removal
WATER PUMP, ALTERNATOR AND AIR CONDITIONER
BELT
1. Remove radiator shroud.
2. Contract and hold the auto tensioner using the following proce-dure.
a. Securely hold the 19 mm (0.75 in) hexagonal portion A of auto tensioner with a closed wrench.
I Preferably use a tool with a handhold of 500 mm (19.69 in) or
more in length.
I No bolts or nuts are required to be loosened during the opera-
tion.
b. Turn the hexagonal portion A in the direction shown by the arrow to contract the damper unit of the auto tensioner.
CAUTION:
I Because the tensioner has a high tension, it shall be
securely held and turned with a closed wrench.
I Because the hexagonal portion A of the tensioner is made
of aluminum and may be damaged by sudden input, turn
it slowly according to the contraction of the damper unit.
3. Remove the belt from the alternator pulley first, and then remove it from the other pulleys.
I If the tensioner is not held firmly, your finger may get caught
between the belt and the pulleys. Confirm the holding of the
tensioner, and then hold the belt side in the place away from
the pulleys to attach or remove the belt, paying attention to
prevent your finger from being caught.
CAUTION:
I When handling the belt, pay attention to prevent the oil or
coolant from adhering to the belt.
I Do not distort or bend the belt intensively.
Installation
IInstall the belt in the reverse order of removal.
I After installation of the belt, confirm that the belt engages the
pulleys securely.
I Depending on the engagement between the belt and the idler
pulley, noise (belt noise) may be heard when the engine is
started just after installation. This noise will stop with time.
Changing Engine Oil
WARNING:
IBe careful not to burn yourself, as engine oil is hot.
I Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com- ponents.
2. Remove drain plug and oil filler cap.

2. Set theGmark of the filter body to the top position and dis-
charge the oil.
I Receive the oil discharged from the drain hose in a tray.
I About 500 cc (17.6 Imp fl oz) of oil will be discharged in about
3 minutes.
I The oil is discharged from the oil catcher to under the vehicle
through the drain hose.
3. Remove the filter body, and then remove the oil filter element.
CAUTION:
I If the engine oil gets on the engine or vehicle, thoroughly
wipe it off.
I Thoroughly wipe off the oil remaining in the oil catcher.
(This is to prevent misidentifying oil leaking from the oil
catcher as oil leaking from the engine.)
4. Remove the O-ring from the filter body.
I Press the O-ring in any direction with your finger, and pull on
the portion of the O-ring separated from the filter body to
remove it.
CAUTION:
Because wire and screwdrivers may cause damage to the fil-
ter body, do not use such tools.
INSTALLATION
1. Thoroughly remove foreign matter adhering to the inside of fil- ter body and O-ring mounting areas (of the body and oil cooler).
2. Install the oil filter element and O-ring to the filter body.
I Securely press the oil filter element into the filter body.
3. Install the filter body.
:20-24N ×m (2.0 - 2.5 kg-m, 15 - 18 ft-lb)
4. After warming up the engine, check that no engine oil leaks.

WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
ÐDRAINING ENGINE COOLANTÐ
1. Move heater TEMP control knob all the way to HOT.
2. Remove undercover and disconnect lower radiator hose to drain coolant.
3. Remove radiator filler cap.
