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

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

ENGINE MAINTENANCE
ENGINE COOLANT : Draining Engine Coolant
INFOID:0000000012432253
WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a th ick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
1. Remove front under cover. Refer to EXT-39, "
FRONT UNDER COVER : Removal and Installation".
2. Connect a suitable hose to the radiator drain plug. • Use a suitable hose with the dimensions as shown.
3. Open radiator drain plug (A) at the bottom of radiator, and then remove radiator cap.
(B): Suitable hose
: Front
CAUTION:
• Perform this step when engine is cold.
• Do not spill engine coolant on the drive belt.
4. It is necessary to drain the cylinder block when drai ning all of engine coolant in the system. To drain the
cylinder block, open the water drain plugs on cylinder block. Refer to EM-93, "
Exploded View".
5. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing. Refer to CO-13, "
Exploded View".
6. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated, flush the engine cooling system. Refer to MA-18, "
ENGINE COOLANT : Flushing Cooling System".
ENGINE COOLANT : RefillingINFOID:0000000012432254
1. Install the radiator drain plug. Install the reservoir tank and cylinder block drain plug, if removed for a total
system drain or for engine removal or repair.
• The radiator must be completely empty of engine coolant and water.
• Apply sealant to the threads of the cylinder block drain plug. Use Genuine High Performance
Thread Sealant or equivalent. Refer to MA-11, "
Fluids and Lubricants".
2. If disconnected, reattach the upper radiator hose at the engine side.
3. Set the vehicle heater controls to the full HOT and heat er ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode. Diameter (A) : 0.8 mm (0.31 in)
Length (B) : 300 mm (11.81 in)
