Checks
Once in Diagnostic Mode (and after identifying the last three alarm triggers in case a theft warning system is
equipped on the vehicle), the following inputs can be tested.
USER ACTION TCU Reaction COMPONENT TESTED
Driver's door opened from closed
(all other doors closed)Hazards flash once Driver's door open signal
Passenger or rear door opened from closed
(all other doors closed)Hazards flash once Door open signal for opened door
Driver's door locked from unlocked Hazards flash once Driver's door status signal
Passenger door locked from unlocked Hazards flash once Assist door status signal
Rear doors locked from unlocked
(with ultrasonic model)Hazards flash once Rear doors status signal
Ultrasonics cancel switch is pressed
(with ultrasonic model)Hazards flash once U/S cancel signal
Trunk or back door is opened from closed Hazards flash once Trunk open signal
Hood is opened from closed
(with ultrasonic model)Hazards flash once Hood open signal
Hazard switch is pressed from off Hazards flash once Hazard switch signal
Turn signal switch is moved to left from off Hazards flash once Left turn signal
Turn signal switch is moved to right from off Hazards flash once Right turn signal
Key turned to lock position in door Hazards flash once * Key cylinder lock switch signal
Lighting switch turned 1st position or 2nd
position from offHazards flash once Tail lamp signal
Key put in ignition cylinder from out Hazards flash once Key in detect signal
Central unlock switch is pressed Hazards flash once Central unlock/Trunk release signal
*) Hazards may flash a second time because of Driver's door status signal change. The min. delay time between flash actions is
100 ms.
In case the system does not operate as described above, check the concerned circuit for open or short.
After completion, the Diagnostic Mode can be switched off by pressing the rear defogger switch or by turning
the ignition to ªONº. The hazard lamp will flash at 3 Hz for 3 seconds to confirm that Diagnostic Mode has

General maintenance includes those items which should be checked during normal day-to-day operation of
the vehicle. They are essential if the vehicle is to continue functioning correctly. Owners can perform the
checks and inspections themselves, or they can be carried out by a NISSAN dealer.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be checked periodically, unless otherwise specified.
TiresCheck the pressure with a gauge weekly when at a service station, including the spare,
and adjust to the specified pressure if necessary. Check carefully for damage, cuts or excessive
wear.Ð
Windshield wiper bladesCheck for cracks or wear if not functioning correctly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
function correctly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch prevents the hood from opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication more
often.MA-45
Tire rotationTires should be rotated every 5,000 km (3,000 miles). MA-43
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating correctly and installed securely. Also check headlight aim.Ð
Warning lights and buzzers/chimesMake sure that all warning lights and buzzers/chimes are
functioning correctly.Ð
Steering wheelCheck that it has the specified play. Check for changes in the steering
operation, such as excessive free play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for
cuts, fraying, wear of damage.MA-46
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the
engine oil or refuel.
Windshield washer fluidCheck that there is adequate fluid in the tank.
Engine coolant levelCheck the coolant level when the engine is cold. MA-22
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off the
engine.MA-21
Brake and clutch fluid levelMake sure that the brake fluid level is between the ªMAXº and
ªMINº lines on the reservoir.MA-36/MA-40
BatteryCheck the fluid level in each cell. It should be between the ªMAXº and ªMINº lines. Ð

2. Before installing new oil filter, clan the oil filter mounting surface
on cylinder block and coat the rubber seal of the oil filter with
a little engine oil.
3. Install oil filter.
When installing oil filter, screw it in until a slight resistance is
felt, then tighten an additional 2/3 turn or more.
4. Add engine oil.
Refer to Changing Engine Oil.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never attempt to change
the coolant when the engine is hot.
1. Set heater ªTEMPº control lever all the way to ªHOTº position.
2. Remove radiator cap and engine under cover.
3. Disconnect lower radiator hose to drain coolant.
Remove reservoir tank, drain coolant, then clean reservoir tank.
Re-install tank temporarily.
4. Remove cylinder block drain plug located at left rear of cylin-
der block.
5. Drain coolant and then tighten drain plug securely.
IApply sealant to the thread of drain
:30-40N×m (3.1 - 4.1 kg-m, 22.1 - 29.5 ft-lb)
6. Connect lower radiator hose.
7. Fill radiator and reservoir tank with water. Re-install radiator
cap and warm up engine.
8. Stop engine and wait until cools down.
9. Drain water.
10. Repeat step 2 through step 9 two or three times, until clear
water begins to drain from radiator.
11. Fill radiator with coolant up to the specified level.
Follow instructions attached to anti-freeze container for mixing
ratio of anti-freeze to water.
Coolant capacity (with reservoir tank):
10.0(8-3/4 Imp qt)
Slowly pour coolant through coolant filler neck to allow air in
system to escape.

HOW TO CHANGE SELF-DIAGNOSIS MODE WITH CONSULT-II
From User Mode to Diagnosis Mode
After selecting ªAIR BAGº on the ªSELECT SYSTEMº screen, User mode automatically changes to Diagno-
sis mode.
From Diagnosis Mode to User Mode
To return to User mode from Diagnosis mode, touch ªBACKº key of CONSULT-II until ªSELECT SYSTEMº
appears, Diagnosis mode automatically changes to User mode.
HOW TO CHANGE SELF-DIAGNOSIS MODE WITHOUT CONSULT-II
From User Mode to Diagnosis Mode
When a malfunction is detected, activate the Diagnosis mode by turning the ignition switch as follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
3) Wait more than 3 seconds.
4) Repeat steps 1 to 3 three times.
5) Turn ignition switch ªONº.
SRS will not enter Diagnosis mode if no malfunction is detected.
From Diagnosis Mode to User Mode
After a malfunction is repaired, switch the ignition ªOFFº for at least one second, then back ªONº. Diagnosis
mode is returned to User mode.
When a malfunction is detected, switch from Diagnosis mode to User mode by turning the ignition switch as
follows:
1) Turn ignition switch ªONº.
2) After ªAIR BAGº warning lamp lights for 7 seconds, turn ignition switch ªOFFº within 1 second.
