CHANGING INVERTER COOLANT
An INFINITI ratailer can change the inverter
coolant. 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
inverter 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
children and pets.
Inverter coolant must be disposed of prop-
erly. Check your local regulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply the parking brake.
2. Run the engine until it reaches operating temperature.
3. Turn off the engine. Wait more than 15
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way.
5. Remove the dipstick again and check the oil level. It should be within the range
.
If the oil level is below, remove the oil
filler cap and pour recommended oil
through the opening. Do not overfill
.6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the break-
in period, depending on the severity of
operating conditions.
CAUTION
Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not covered
by warranty.
