• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside timing chain tensioner dr ops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

NOTE:
• Maintenance items with “ ” shoul d be performed more frequently according to “Maintenance Under Severe Driving Condi-
tions”.
• (1) Use only Genuine NISSAN CVT fluid. If towing a trailer, using a camper or a car-top carrier or driving on rough or muddy r oads,
inspect CVT fluid deteriorat ion at NISSAN dealer every 60,000 miles (96,000 km), then change CVT fluid if necessary. And if the
inspection is not performed, change (not just inspect) CVT fluid every 60,000 miles (96,000 km). Using transmission fluid other than
Genuine NISSAN CVT Fluid will damage the CVT, which is not covered by the NISSAN new vehicle limited warranty.
• (2) Refer to “Tire rotation” under the “GENERAL MAINTENANCE” heading earlier in this section.
MAINTENANCE UNDER SEVERE DRIVING CONDITIONS
The maintenance intervals shown on the preceding pages are for normal operating conditions. If the vehicle is
mainly operated under severe driving conditions as shown below, more frequent maintenance must be per-
formed on the following items as shown in the table.
Severe driving conditions
• Repeated short trips of less than 5 miles (8 km).
• Repeated short trips of less than 10 miles (16 km) wi th outside temperatures remaining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances , such as police, taxi or door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy, or salt spread roads.

*1: For additional information, see “Engine Oil Recommendation”.
*2: As an alternative to this recommended oil, SAE 5W-30 conventional petroleum based oil may be used and meet all specificatio ns
and requirements necessary to maintain the New Vehicle Limited Warranty.
*3: NISSAN recommen ds Genuine NISSAN Ester Oil av ailable at a NISSAN dealer.
*4: Use only Genuine NISSAN CVT Fluid NS -3, using automatic transmission fluid other than Genuine NISSAN CVT Fluid NS-3
will damage the CVT, which is not covered by the NISSAN new vehicle limited warranty.
*5: Use of a power steering fluid other than Genuine NISSAN E-PSF will prevent the power steering system from operating properly.
*6: Available in mainland U. S.A. through a NISSAN dealer.
*7: For additional information, see "Air conditioner specification label".
FOR USA AND CANADA : En gine Oil RecommendationINFOID:0000000009464537
NISSAN recommends the use of an energy conserving o il in order to improve fuel economy. Select only
engine oils that meet the American Petroleum Institut e (API) certification and International Lubricant Standard-
ization and Approval Committee (ILSAC) certificati on and SAE viscosity standard. These oils have the API
certification mark on the front of the container. Oils which do not have the specified quality label should not be
used as they could cause engine damage.

1. Install the radiator drain plug. Install the reservoir tank and cylin-
der block drain plug, if removed for a total system drain or for
engine removal or repair.
• The radiator must be completely empty of coolant and
water.
• Apply sealant to the threads of the cylinder block drain
plug. Use Genuine High Pe rformance Thread Sealant or
equivalent. Refer to GI-21, "Recommended Chemical
Products and Sealants".
: Front
CAUTION:
Do not reuse copper sealing washers.
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.
4. Install the Tool by installing the radiator cap adapter onto the radiator neck opening. Then attach the gauge body assembly
with the refill tube and the venturi assembly to the radiator cap
adapter.
5. Insert the refill hose into the coolant mixture container that is
placed at floor level. Make sure the ball valve is in the closed
position.
• Use recommended coolant or equivalent.
Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubri-
cants".
CAUTION:
Do not use any cooling system additives such as radiator
sealer. Additives may clog th e cooling system and cause
damage to the engine, transmission and/or cooling system.
6. Install an air hose to the venturi assembly, the air pressure must be within specification.
CAUTION:
The compressed air supply must be equipped with an air dryer.
7. The vacuum gauge will begin to rise and there will be an audible hissing noise. During this process open the ball valve on the refill hose slightly. Coolant will be vi sible rising in the refill hose. Once the refill hose is
full of coolant, close the ball valve. Th is will purge any air trapped in the refill hose.

CVT FLUID : AdjustmentINFOID:0000000009464569
CAUTION:
• During adjustment of the CVT fluid level, check CO NSULT so that the oil temperature may be main-
tained from 35 to 45 °C (95 to 113 °F).
• During adjustment of the CVT fluid level, check that the engine speed is maintaining 500 rpm.
• Use caution when looking into the drain hole as th ere is a risk of dripping fluid entering the eye.
1. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
2. Start the engine.
3. Adjust the CVT fluid temperature to be approximately 40 °C (104 °F).
NOTE:
The CVT fluid is largely affected by temperature. Therefore be sure to use CONSULT and check the
“FLUID TEMP” under “TRANSMISSION” in “Data Monitor” while adjusting.
4. While depressing the brake pedal, shift the selector lever to the entire position from “P” to “DS”, and shift it to the “P” position.
NOTE:
Hold the lever at each position for 5 seconds.
5. Lift up the vehicle.
6. Check that there is no CVT fluid leakage.
7. Remove the overflow plug from converter housing.
8. Install the charging pipe set (KV311039S0) (A) into the overflow plug hole.
CAUTION:
Tighten the charging pipe by hand.
9. Install the ATF changer hose (B) to the charging pipe. CAUTION:
Press the ATF changer hose all the way onto the charging
pipe until it stops.
10. Fill approximately 0.5 liter (1/2 US qt, 1/2 lmp qt) of the CVT
fluid.
11. Remove the ATF changer hose from the charging pipe, and check that the CVT fluid drains out from the charging pipe. If it
does not drain out, perform charging again.
CAUTION:
Perform this work with the vehicle idling.
12. When the flow of CVT fluid slows to a drip, re move the charging pipe from the converter housing.
13. Tighten the overflow plug to the specified torque. Refer to TM-186, "Exploded View"
.

• If anything is found, repair or replace damaged parts and adjust
CVT fluid level. Refer to TM-286, "Adjustment"
.
CVT FLUID : ReplacementINFOID:0000000009464572
CAUTION:
• Always use shop paper. Do not use shop cloth.
• Replace a drain plug gasket with new ones at the fi nal stage of the operation when installing.
• Use caution when looking into the drain hole as there is a risk of dripping fluid entering the eye.
• After replacement, always pe rform CVT fluid leakage check.
1. Select “Data Monitor” in “TRANSMISSION” using CONSULT.
2. Select “FLUID TEMP” and confirm t hat the CVT fluid temperature is 40°C (104 °F) or less.
3. Check that the selector lever is in the “P ” position, then completely engage the parking brake.
4. Lift up the vehicle.
5. Remove the drain plug and drain the CVT fluid from the oil pan. Refer to TM-387, "Exploded View"
