CHECKING INVERTER COOLANT LE-
VEL
Check the coolant level in the reservoir
when the engine and inverter are cold. If
the coolant level is below the MIN level
*B,
add coolant to the MAX level
*A.
If the inverter cooling system frequently
requires coolant, have it checked by an
INFINITI retailer.
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
properly. Check your local regulations.

9-6Technical and consumer information
above symptoms are encountered, have
your vehicle checked at an INFINITI retailer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

ENGINE OIL AND OIL FILTER RE-
COMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see“Capacities and recommended fuel/
lubricants” (P.9-2). INFINITI recommends
the use of an energy conserving oil in
order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certifi-
cation or International Lubricant Standar-
dization and Approval Committee (ILSAC)
certification 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.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.

361-4792.WARNING
A vehicle equipped with Intelligent All-
Wheel Drive (AWD) should never be tested
using a two wheel dynamometer (such as
the dynamometers used by some states for
emissions testing), or similar equipment.
Make sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Using
the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be
in what is called the“ready condition”for
an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is
repaired or the 12-volt battery is discon-
nected, the vehicle may be reset to a “notready condition”. Before taking the I/M
test, check the vehicle’s inspection/main-
tenance test readiness condition. Place the
ignition switch in the ON position without
starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for
20 seconds and then blinks for 10
seconds, the I/M test condition is
“not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”.
Contact an INFINITI retailer to set the
“ready condition” or to prepare the vehicle
for testing.
