INFOID:0000000012431986
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precautions For Refrigerant System ServiceINFOID:0000000012431987
WORKING WITH HFC-134a (R-134a)
CAUTION:
• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. Compressor mal-
function is likely to occur if the refrigerants are mixed, refe r to “CONTAMINATED REFRIGERANT”
below. To determine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use Refriger-
ant recovery/recycling recharging equi pment and Refrigerant Identifier.
• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
Compressor malfunction is likely to occur if oil other than that specified is used.
• The specified HFC-134a (R-134a) oi l rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
- Cap (seal) the component immediately to minimize the entry of moisture from the atmosphere when removing refrigerant components from a vehicle.
- Do not remove the caps (unseal) unti l just before connecting the components when installing refrig-
erant components to a vehicle. Connect all refr igerant loop components as quickly as possible to
minimize the entry of moisture into system.
- Use only the specified oil from a sealed container. Reseal containers of oil immediately. Oil becomes
moisture saturated and should no t be used without proper sealing.
- Do not allow oil to come in contact with styrene foam parts. Damage may result.
GENERAL REFRIGERANT PRECAUTION
WARNING:
• Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Remove HFC-134a (R-134a) from the A/C system, usin g certified service equipment meeting require-
ments of SAE J-2210 [HFC-134a (R-134a) recycling equipment] or J-2209 [HFC-134a (R-134a) recov-
ery equipment]. Ventilate work area before resumi ng service if accidental system discharge occurs.
Additional health and safety in formation may be obtained from refrigerant and oil manufacturers.
• Do not release refrigerant into the air. Use ap proved recovery/recycling recharging equipment to
capture the refrigerant each time an air conditioning system is discharged.
• Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
• Do not store or heat refrigerant containers above 52 °C (126° F).
• Do not heat a refrigerant containe r with an open flame; Place the bottom of the container in a warm
pail of water if container warming is required.
• Do not intentionally drop, puncture or incinerate refrigerant containers.
• Do not refrigerant away from op en flames; poisonous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen; therefore be certain to work in well ventilated areas to prevent suffo- cation.
• Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition-
ing systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a) have
been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or
property damage. Additional heal th and safety information may be obtained from refrigerant manu-
facturers.
REFRIGERANT CONNECTION
A new type of refrigerant connection has been introduced to al l refrigerant lines except the following locations:

PERIODIC MAINTENANCE
GENERAL MAINTENANCE
Explanation of Gene
ral MaintenanceINFOID:0000000012432243
General maintenance includes those items which shoul d be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operati ng properly. The owners can perform the
checks and inspections themselves or they can have their NISSAN dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle,
etc.
Item Reference page
Tires Check the pressure with a gauge often and always prior to long distance trips.
Adjust the pressure in all tires, including the spare, to the specified pressure.
Check carefully for damage, cuts or excessive wear. WT-54
Wheel nuts
When checking the tires, make sure no nuts are missing, and check for any loose
nuts. Tighten if necessary. WT-48
Tire rotation
Tires should be rotated every 5,000 miles (8,000 km). WT-45
Tire Pressure Monitor-
ing System (TPMS)
transmitter compo-
nentsReplace the TPMS transmitter grommet seal, valve core and cap when the tires
are replaced due to wear or age.
WT-53
Wheel alignment and
balanceIf the vehicle should pull 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. For additional information regarding tires, refer
to "Important Tire Safety Information" (US) or "Tire Safety Information" (Canada)
in the NISSAN Warranty
Information Booklet. WT-44
WT-45
Windshield
Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary. GW-12
Windshield wiper
bladesCheck for cracks or wear if they do not wipe properly.
—
Doors and engine
hood Check that all doors and the engine hood operate smoothly as well as the back
door, trunk lid and back hatch. Also make sure that all latches lock securely. Lu-
bricate 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 lubrica-
tion frequently. MA-40
MA-41

Lamps
Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and oth-
er lamps are all operating properly and installed securely. Also check headlamp
aim. Clean the headlamps on a regular basis. EXL-98
