Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
Precautions for Supplemental Restraint System
(SRS) “AIR BAG” and “SEAT BELT
PRE-TENSIONER”
The Supplemental Restraint System such as “AIR BAG” used along with a seat belt, helps to reduce the risk
or severity of injury to the driver and front passenger for certain types of collision. The SRS system composition which is available to INFINITI QX4 is as follows:
쐌For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the steering wheel), front passenger air bag module (located on the instrument panel on passenger side), seat belt
pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
쐌For a side collision
The Supplemental Restraint System consists of side air bag module (located in the outer side of front seat),
satellite sensor, diagnosis sensor unit (one ofcomponents of air bags for a frontal collision),wiring harness,
warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in the RS section of this Service Manual.
WARNING:
쐌To 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 INFINITI dealer.
쐌Improper 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 RS section.
쐌Do 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 harness connector (and by yellow harness protector or yellow insulation tape before the harness connectors).

GENERAL MAINTENANCE
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform
checks and inspections themselves or they can have their INFINITI dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.

GI
TiresCheck the pressure with a gauge, including the spare, at least once a month
and always prior to a long distance trips. Adjust to the specified pressure if
necessary. Check carefully for damage, cuts or excessive wear.
Wheel nutsWhen checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.
Tire rotationTires should be rotated every 12,000 km (7,500 miles).MA-25

If the vehicle pulls to either side while driving on a straight and level road, or
if you detect uneven or abnormal tire wear, there may be a need for wheel
alignment. If the steering wheel or seat vibrates at normal highway speeds,
wheel balancing may be needed.
Check for cracks or wear if they do not wipe properly.—
Check that all doors and the engine hood operate smoothly as well as the
trunk lid and back hatch. Also make sure that all latches lock securely. Lubricate if necessary. Make sure that the secondary latch keeps the hood from
opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check
lubrication frequently.

Anti-freeze Coolant Mixture Ratio
The engine cooling system is filled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only a Genuine Nissan anti-freeze coolant or equivalent with the proper
mixture ratio of 50% anti-freeze and 50% demineralized water/
distilled water. Other types of coolant solutions may damage
your engine cooling system.

WARNING:
To avoid the danger of being scalded, never change the coolant when the engine is hot.
—DRAINING ENGINE COOLANT—
1.Set air conditioning system as follows to prevent coolant from
remaining in the system.
a.Turn ignition switch “ON” and set temperature controller to
maximum hot position.
b.Wait 10 seconds before turning ignition switch “OFF”.
2.Open radiator drain plug at the bottom of radiator.
3.Remove radiator filler cap.
쐌Be careful not to allow coolant to contact drive belts.
When draining all the coolant in the system, also perform the following two steps.
1)Open drain plugs on right side of cylinder block and water
pump side, then open air relief plugs to drain coolant.
2)Check drained coolant for contaminants such as rust, corrosion or discoloration. If contaminated flush engine cooling

1.Install reservoir tank if removed, and radiator drain plug.
2.Close and tighten cylinder block drain plugs securely if
removed.
쐌Apply sealant to the thread of cylinder block drain plugs.
Use Genuine Thread Sealant or equivalent. Refer to GI-53.
3.Fill radiator slowly with coolant.
If air relief plug was removed, fill until coolant spills from the
air relief plug, then install air relief plug.
4.Fill reservoir tank if removed with coolant up to the MAX level
and install radiator cap.
Use Genuine Nissan antifreeze coolant or equivalent mixed
with demineralized water/distilled water.
For coolant mixture ratio, refer to “RECOMMENDED FLUIDS AND
LUBRICANTS”, MA-13.
Coolant capacity (Without reservoir tank):
8.6 (9-1/8 US qt, 7-5/8 Imp qt)
Reservoir tank capacity (for MAX level):
0.6 (5/8 US qt, 1/2 Imp qt)
Pour coolant through coolant filler neck slowly to allow air in
system to escape.
5.Warm up engine to normal operating temperature with radiator cap installed.
6.Run engine at 2,500 rpm for 10 seconds and return to idle
speed.
쐌Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
7.Stop engine and cool it down.
쐌Cool down using a fan to reduce the time.
8.Refill reservoir tank to Max line with coolant.
9.Repeat steps 5 through step 8 two or more times until coolant
level no longer drops.
10. Check cooling system for leaks with engine running.
11. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater temperature control set at several positions between COOL and HOT.
쐌Sound may be noticeable at heater water cock.
12. If sound is heard, bleed air from cooling system by repeating
steps 5 through 8 until coolant level no longer drops.

1.Warm up engine.
2.Check for fluid leakage.
3.Before driving, fluid level can be checked at fluid temperatures
of 30 to 50°C (86 to 122°F) using “COLD” range on dipstick.
a.Park vehicle on level surface and set parking brake.
b.Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c.Check fluid level with engine idling.
d.Remove dipstick and note reading. If level is at low side of
either range, and fluid to the charging pipe.
e.Re-insert dipstick into charging pipe as far as it will go.
f.Remove dipstick and note reading. If reading is at low side of
range, add fluid to the charging pipe.
Do not overfill.
4.Drive vehicle for approximately 5 minutes in urban areas.
5.Re-check fluid level at fluid temperatures of 50 to 80°C (122
to 176°F) using “HOT” range on dipstick.
CAUTION:
Securely install A/T fluid level gauge.
6.Check fluid condition.
쐌If fluid is very dark or smells burned, refer to AT section for
checking operation of A/T. Flush cooling system after repair of
A/T.
쐌If A/T fluid contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T.Refer to LC-21, “Radiator”.
