*1: For further details, see “SAE Viscosity Number”.
*2: Never use API CG-4.
*3: Use Genuine Nissan Anti-freeze Coolant (L250) or equivalent in its quality, in order to avoid possible aluminum corrosion w ithin the
engine cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may not be
covered by the warranty even if such incidents occurred during the warranty period.

Changing Engine OilELS000CH
WARNING:

Be careful not to burn yourself, as the engine oil is hot.

Prolonged and repeated contact with used engine oil may cause skin cancer: try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine oil leakage from engine components.
2. Stop engine and wait for 10 minutes.
3. Loosen oil filter cap and then remove drain plug.
4. Drain engine oil.
5. Install drain plug with new washer. Refer to EM-147, "

REMOVAL
1. Open oil filter installation/ removal cover on RH engine undercover.
2. Using the oil filter wrench, remove the oil filter.
CAUTION:

Be careful not to get burned when the engine and engine oil are hot.

When removing, prepare a shop cloth to absorb any engine oil leakage or spillage.

Do not allow engine oil to adhere to the drive belts.

Completely wipe off any engine oil that adhere to the engine and the vehicle.Oil pan drain plug:

Changing M/T OilELS000BD
1. Drain oil from drain plug and refill with new gear oil.
2. Check oil level.
CAUTION:
Do not reuse gasket.
Checking A/T FluidELS000BV
1. Warm up engine.
2. Check for fluid leakage.
3. Before driving, fluid level can be checked at fluid temperatures of 30 to 50°C (86 to 122°F) using “COLD”
range on dipstick.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear position. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove dipstick and wipe clean lint-free paper.
CAUTION:
When wiping away the dipstick, always use lint-free paper, not cloth one.
e. Re-insert dipstick into charging pipe as far as it will go.
CAUTION:
To check fluid level, insert the dipstick until the cap contacts the end of the A/T fluid charging pipe,
with the dipstick reversed from the normal attachment conditions.
f. Remove dipstick and note reading. If reading is at low side of range, add fluid to the A/T fluid charging
pipe.
CAUTION:
Do not overfill.
4. Drive vehicle for approximately 5 minutes in urban areas.
5. Re-check fluid level at fluid temperatures of 50 to 80°C (122 to 176°F) using “HOT” range on dipstick.
CAUTION:

When wiping away the dipstick, always use lint-free paper, not cloth one.

To check fluid level, insert the dipstick until the cap contacts the end of the A/T fluid charging
pipe, with the dipstick reversed from the normal attachment conditions.Oil grade:
