6. Close the air relief plug and run the engine at 2,000 rpm until the upper hose becomes hot and radiator
fan operates. Leave the engine running approximately 5 minutes at idle speed and check for sound of
coolant flow while running engine from idle up to 3,000 rpm.
 Sound may be noticeable at heater water cock.
7. If sound is heard, bleed air from cooling system by repeating steps 4 to 6 until coolant level no longer
drops.
 Check the radiator lower hose for any signs of leakage.
8. Turn off the engine and let it cool down.
 Cool down using a fan to reduce the time.
9. After cooling period, loosen the air relief plug and check if coolant spills from the air relief hole. if not,
remove the air relief plug until the coolant spills, and then close the relief air plug. Bleed air from cooling
system by repeating steps 6 to 10 until the coolant spills immediately.
10. Check the engine coolant level when engine is cool and refill to MAX level line if the level is lower.
 Clean excess coolant from engine.
11. Check that the reservoir tank cap is tightened.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001724583
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
WARNING:
• To 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 performed by
an authorized NISSAN/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
 Do 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 har-
ness connectors.
Precaution for Rear SuspensionINFOID:0000000001724584
 When installing the rubber bushings, the final tightening must be done under unladen condition and with the
tires on level ground. Oil will shorten the life of the rubber bushings, so wipe off any spilled oil immediately.
 Unladen condition means the fuel tank, engine coolant and lubricants are at the full specification. The spare
tire, jack, hand tools, and mats are in their designated positions.
 After installing suspension components, check the wheel alignment.
 Caulking nuts are not reusable. Always use new caulking nuts for installation. New caulking nuts are pre-
oiled, do not apply any additional lubrication.

Make sure the mounting conditions (looseness, backlash) of each component and component conditions
(wear, damage) are within specifications.
SHOCK ABSORBER INSPECTION
Check shock absorber for oil leakage, damage and replace it if necessary.
Wheel AlignmentINFOID:0000000001724576
DESCRIPTION
Measure wheel alignment under unladen conditions.
NOTE:
“Unladen conditions” means that fuel, engine coolant, and lubricant are full. Spare tire, jack, hand tools and
mats are in designated positions.
PRELIMINARY
Check the following:
1. Tires for improper air pressure and wear.
2. Road wheels for runout. Refer to WT-5, "
Inspection" .
3. Wheel bearing axial end play. Refer to RAX-5, "
On-Vehicle Inspection and Service" .
4. Shock absorber operation.
5. Each mounting part of suspension for looseness and deformation.
6. Rear suspension beam for cracks, deformation, and other damage.
7. Vehicle height (posture).
GENERAL INFORMATION AND RECOMMENDATIONS
1. A Four-Wheel Thrust Alignment should be performed.
 This type of alignment is recommended for any NISSAN vehicle.
 The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel
is centered.
 The alignment machine itself should be capable of accepting any NISSAN vehicle.
 The alignment machine should be checked to ensure that it is level.
2. Make sure the alignment machine is properly calibrated.
 Your alignment machine should be regularly calibrated in order to give correct information.
 Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to RSU-5, "Wheel
Alignment" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.
 The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.
 This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.
 Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.
 See Instructions in the alignment machine you are using for more information.
