PRECAUTIONS

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
Precautions for Supplemental Restraint System (SRS) AIR BAGand 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:
For 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.
For 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:
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 INFINITI dealer.
Improper 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.
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 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.
Item Reference page
GI
Tires Check 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 nuts When checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.
Tire rotation Tires should be rotated every 12,000 km (7,500 miles). MA-25 Wheel alignment and
balance
Windshield wiper blades
Doors and engine hood
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.

GASOLINE ENGINE OIL

SAE 5W-30 viscosity oil is preferred for all ambient temperatures. SAE 10W-30, 10W-40 viscosity oil may be used if the ambient temperature is above −18°C (0°F).

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.

1. Set air conditioning system as follows to prevent coolant from remaining in the system.
a. Turn ignition switch ONand 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.
Be 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 system, Refer to FLUSHING COOLING SYSTEM, MA-16.

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.
Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the engine.
7. Stop engine and cool it down.
Cool 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.
Sound 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.
Clean excess coolant from engine.

3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
