CHECKING INVERTER COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine and inverter are cold. The coolant
level should be between the MIN level
B, add
coolant to the MAX level
A.
If the inverter cooling system frequently
requires coolant, have it checked by a
INFINITI retailer.
CHANGING INVERTER COOLANT
Major cooling system repairs should be done by a
INFINITI retailer. The service procedure can be
found in the INFINITI Service Manual.
Improper servicing can result in inverter
overheating.
WARNING
● To avoid the danger of being scalded,
never change the coolant when the in-
verter is hot.
● Never remove the cap when the inverter
is hot. Serious burns could be caused by
high pressure fluid escaping from the
inverter coolant reservoir.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way.
