NOTICE:
Only use ND-OIL11 for the electric inverter compressor of the air conditioning system. Using other compressor
oils may be dangerous, as they may conduct electricity.
Electrical insulation performance may decrease significantly if even a small amount of oil other than ND-OIL11 is
used (or enters) in the refrigeration cycle, causing a DTC to be output.
If other oil is accidentally used and a DTC is output, collect the compressor oil in the compressor and replace it
with ND-OIL11 to increase the ND-OIL11 ratio amount.
Replace the main components (evaporator, condenser, and compressor) if a large amount of oil other than ND-
OIL11 enters the system. Failing to do so may cause electrical insulation performance to remain low, causing a
DTC to be output.
14. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(a) This vehicle is equipped with an Supplemental Restraint System (SRS) such as the driver, front passenger,
side and curtain shield airbags. Failure to carry out service operations in the correct sequence could cause the
SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing
(including removal or installation of parts, inspection or replacement), be sure to read the precautionary notices
.
15. PRECAUTIONS WHEN WORKING (w/ Remote Air Conditioning System and Solar Ventilation System)
(a) Vehicles with the remote air conditioning system have the following risks that it is necessary to be aware of
when performing repairs. Therefore, make sure to take care of the key (electrical transmitter) carefully so that
the remote air conditioning system is not operated unexpectedly.
Risks
The electrical fan and other items in the engine compartment may operate resulting in various hazards.
The wipers may operate if the wiper switch is in the on position when the remote air conditioning system is
activated. If this occurs, there is the potential for damage to the glass, wipers or injury.
When the light control switch is in the tail, head or AUTO position, the headlights may turn on.
Short circuits may occur if electrical inspections are being performed when the remote air conditioning system
is turned on, because the IG circuit is powered at this time.
CAUTION:
Failure to take proper care with the key (electrical transmitter) may cause the system to be accidentally
operated. This can lead to an accident and damage to parts or a serious injury.
HINT:
Make sure to store the key (electrical transmitter) in a box with the switch side facing up, and place the box
where it can be monitored so that no one cannot operate the remote A/C switch.
(b) When performing repairs on vehicles with the solar ventilation system, turn the solar ventilation switch off.
