Precautions For High-Voltage System
PRECAUTION FOR HIGH-VOLTAGE CIRCUIT
NOTE: The hybrid system contains a 244.8 V high-voltage system with a strong alkali solution of potassium hydroxide. Be sure to follow the instructions in this manual to handle the system correctly. Failure to do so may result in serious injury or electrocution.
1. Engineer must undergo special training to be able to perform high-voltage system inspection and servicing.
2. High-voltage cables are colored orange. The HV battery and other high-voltage components have"high voltage" caution labels. Do not carelessly touch these wires and components.
3. Before inspecting or servicing the high-voltage system, be sure to follow safety measures, such as wearing insulated gloves and removing the service plug to prevent electrocution. Carry the removed service plug in your pocket to prevent other technicians from reinstalling it while your are servicing the vehicle.
NOTE:
- Before removing the service plug, confirm ignition switch off.
- Do not put the vehicle into the ON (READY) state after removing the service plug grip as the ECU may be damaged.
ON (READY): The condition which the ready indicator lamp illuminates and vehicle is ready to be driven.
- Turn the ignition switch off, wear insulated gloves, and disconnect the negative terminal of the auxiliary battery before touching any of the orange-colored wires of the high-voltage system.
- Turn the ignition switch off before performing any resistance checks.
- Turn the ignition switch off before disconnecting or reconnecting any connectors.
4. After removing the service plug, wait 10 minutes before touching any of the high-voltage connectors and terminals.
NOTE: 10 minutes are required to discharge the high-high-voltage voltage condenser inside the inverter.
5. Before wearing insulated gloves, make sure that they are not cracked, ruptured, torn, or damaged in any way. Do not wear wet insulated gloves.
6. When servicing the vehicle, do not carry metal objects like mechanical pencils or scales that can be dropped accidentally and cause a short circuit.
7. Before touching a bare high-voltage terminal, wear insulated gloves and use a tester to make sure that the terminal voltage is 0 V.
8. After disconnecting or exposing a high-voltage connector or terminal, insulate it immediately using insulation tape.
9. The screw of a high-voltage terminal should be tightened firmly to the specified torque. Both insufficient and excessive torque can cause failure.
10. Use the "CAUTION: high-voltage. DO NOT TOUCH DURING OPERATION" sign to notify other engineers that a high-voltage system is being inspected and/or repaired.high-voltage
11. After servicing the high-voltage system and before reinstalling the service plug, check again that you have not left a part or tool inside, that the high-voltage terminal screws are firmly tightened, and that the connectors are correctly connected.high-voltage
12. Do not place the battery upside down while removing and installing it.
PERSONAL PROTECTIVE EQUIPMENT
When engaged in operations such as removal and installation related to high-voltage equipment, use personal protective equipment to avoid death or serious personal injury from electric shock.
INSULATION RESISTANCE CHECK TOOL
When making an insulation resistance check, the tester which can measure the resistance with applying 1000 V is necessary.
PERSONAL PROTECTIVE EQUIPMENT CHECK
Inspect the personal protective equipment before use.
WARNING: Personal protective equipment must not have abnormalities such as scratches and tears which will influence the insulation performance.
INSULATION RESISTANCE CHECK OF INSULATION GLOVES
Check before starting work
Before wearing insulated gloves, check that gloves are not cracked, ruptured, torn, or damaged by inflating.
Inspect insulation resistance of insulation gloves regularly (at least every six months)
1. Put the insulation glove into a water tank filled with water.
2. Pour water into the insulation glove.
NOTE: Pour water into the glove so that water does not splash on the sleeve of the glove. If water splash on the sleeve of the glove, the insulation cannot be checked accurately because the continuity may exist through water for the insulation resistance check even if the glove has no problems.
3. Inspect the resistance between water in the water tank and water inside the glove by applying 1000 V using the insulation tester.
Resistance: Should be more than 1 Mohm.
WARNING:
- Use insulation gloves for insulation check.
- Dry the checked insulation gloves completely after the insulation resistance check.
Supplemental Restraint System (SRS)"AIR BAG" and"SEAT BELT PRE-TENSIONER"
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 Airbag system and Seat Belt system.
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 Airbag system.
- Do not use electrical test equipment on any circuit related to the SRS unless instructed. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.

General Precautions
- Do not operate the engine for an extended period of time without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable materials. Special care should be taken when handling any inflammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials. Do not smoke while working on the vehicle.
- Before jacking up the vehicle, apply wheel chocks or other tire blocks to the wheels to prevent the vehicle from moving. After jacking up the vehicle, support the vehicle weight with safety stands at the points designated for proper lifting before working on the vehicle. These operations should be done on a level surface.
- When removing a heavy component such as the engine or transaxle/transmission, be careful not to lose your balance and drop them. Also, do not allow them to strike adjacent parts, especially the brake tubes and master cylinder.
- Before starting repairs which do not require 12-volt battery power:
Turn off ignition switch.
Disconnect the negative 12-volt battery terminal.
- If the 12-volt battery terminals are disconnected, recorded memory of radio and each control unit is erased.
- To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
- Dispose of drained oil or the solvent used for cleaning parts in an appropriate manner.
- Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.
- Clean all disassembled parts in the designated liquid or solvent prior to inspection or assembly.
- Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new ones.
- Replace inner and outer races of tapered roller bearings and needle bearings as a set.
- Arrange the disassembled parts in accordance with their assembled locations and sequence.
- Do not touch the terminals of electrical components which use microcomputers (such as ECM). Static electricity may damage internal electronic components.
- After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
- Use only the fluids and lubricants specified in this manual.
- Use approved bonding agent, sealants or their equivalents when required.
- Use hand tools, power tools (disassembly only) and recommended special tools where specified for safe and efficient service repairs.
- When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
- Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate covers. Take caution that keys, buckles or buttons do not scratch paint.
WARNING: To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness connectors which are related to the engine control system and TCM (transmission control module) system. The connectors should be disconnected only when working according to the WORK FLOW of TROUBLE DIAGNOSIS.
Three Way Catalyst
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To prevent this, follow the instructions.
- Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
- When checking for ignition spark or measuring engine compression, make tests quickly and only when necessary.
- Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three way catalyst.
Fuel (Regular Unleaded Gasoline Recommended) QR25DE
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91).
CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect the emission control devices and systems, and could also affect the warranty coverage validity.
Multiport Fuel Injection System or Engine Control System
- Before connecting or disconnecting any harness connector for the multiport fuel injection system or ECM:
Turn ignition switch to "OFF" position.
Disconnect negative 12-volt battery terminal.
Otherwise, there may be damage to ECM.
- Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure.
- Be careful not to jar components such as ECM and mass air flow sensor.
Hoses
HOSE REMOVAL AND INSTALLATION
- To prevent damage to rubber hose, do not pry off rubber hose with tapered tool or screwdriver.
- To reinstall the rubber hose securely, make sure that hose insertion length and orientation is correct. (If tube is equipped with hose stopper, insert rubber hose into tube until it butts up against hose stopper.)
HOSE CLAMPING
- If old rubber hose is re-used, install hose clamp in its original position (at the indentation where the old clamp was). If there is a trace of tube bulging left on the old rubber hose, align rubber hose at that position.
- Discard old clamps; replace with new ones.
- After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.
Engine Oils
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.
HEALTH PROTECTION PRECAUTIONS
- Avoid prolonged and repeated contact with oils, particularly used engine oils.
- Wear protective clothing, including impervious gloves where practicable.
- Do not put oily rags in pockets.
- Avoid contaminating clothes, particularly underpants, with oil.
- Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regularly.
- First aid treatment should be obtained immediately for open cuts and wounds.
- Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
- Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed.
- Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
- If skin disorders develop, obtain medical advice without delay.
- Where practical, degrease components prior to handling.
- Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face shields; in addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste disposal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.
The regulations concerning pollution vary between regions.
Air Conditioning
Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to "HFC-134a (R-134a) Service Procedure".
