PRECAUTIONS < SERVICE INFORMATION >
SERVICE INFORMATION PRECAUTIONS Description
INFOID:0000000005282865
Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER"
INFOID:0000000005570705
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 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 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 harness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service.
Precaution Necessary for Steering Wheel Rotation After Battery Disconnect INFOID:0000000005282867
NOTE: • This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYSTEM). • Remove and install all control units after disconnecting both battery cables with the ignition knob in the ″LOCK″ position. • Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results. For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mechanism is adopted on the key cylinder. For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering wheel rotation will become impossible. If steering wheel rotation is required when battery power is interrupted, follow the procedure below before starting the repair operation.
OPERATION PROCEDURE 1.
Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged.
Revision: January 2010
GI-2
2010 Sentra
PRECAUTIONS < SERVICE INFORMATION > 2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the steering lock will be released. GI 3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated. 4. Perform the necessary repair operation. B 5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting the battery cables. (At this time, the steering lock mechanism will engage.) C 6. Perform a self-diagnosis check of all control units using CONSULT-III.
General Precaution
INFOID:0000000005282868
D
• 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 flammable materials. Special care should be taken when handling any flammable 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.

F
SGI285
• 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.

SGI231
• Before starting repairs which do not require battery power: Turn off ignition switch. Disconnect the negative battery terminal. • If the battery terminals are disconnected, recorded memory of radio and each control unit is erased. • Battery posts, terminals and related accessories contain lead and lead compounds. Wash hands after handling.

N SEF289H
• To prevent serious burns: Avoid contact with hot metal parts. Do not remove the radiator cap when the engine is hot. • Dispose of or recycle 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.

Precaution for Three Way Catalyst
INFOID:0000000005282869
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.
Precaution for Fuel (Unleaded Regular Gasoline Recommended) MR20DE and QR25DE Except SE-R Spec-V
INFOID:0000000005282870
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (research octane number 91). E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) may only be used in vehicles specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models). CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel other than that specified could adversely affect the emission control devices and systems, and could Revision: January 2010

Precaution for Engine Oils
INFOID:0000000005282874
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.
