Your vehicle is filled with R-134a or
R-1234yf according to the regulation in
your country at the time of producing.
You can find out which air conditioning
refrigerant is applied your vehicle at
the label inside of engine room. Refer
to Refrigerant label on page 9-27
for more detail location of air condition‐
ing refrigerant label.
CAUTION
• The refrigerant system should on‐
ly be serviced by trained and certi‐
fied technicians to insure proper
and safe operation.
• The refrigerant system should be
serviced in a well-ventilated place.
• The air conditioning evaporator
(cooling coil) shall never be re‐
paired or replaced with one re‐
moved from a used or salvaged
vehicle and new replacement MAC
evaporators shall be certified (and
labeled) as meeting SAE Standard
J2842.
NOTICE
• When using the air conditioning
system, monitor the temperature
gauge closely while driving up hills
or in heavy traffic when outside
temperatures are high. Air condi‐
tioning system operation may
cause engine overheating. Contin‐
ue to use the blower fan but turn
the air conditioning system off if
the temperature gauge indicates
engine overheating.
• When opening the windows in hu‐
mid weather air conditioning may
create water droplets inside the
vehicle. Since excessive water
droplets may cause damage to
electrical equipment, air condition‐
ing should only be used with the
windows closed.
Air conditioning system operation
tips
• If the vehicle has been parked in di‐
rect sunlight during hot weather,
open the windows for a short time to
let the hot air inside the vehicle es‐
cape.
• Use air conditioning to reduce humidi‐
ty and moisture inside the vehicle on
rainy or humid days.
• During air conditioning system opera‐
tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
• Use the air conditioning system every
month only for a few minutes to en‐
sure maximum system performance.
• When using the air conditioning sys‐
tem, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side of
the vehicle. This is a normal system
operation characteristic.
• Operating the air conditioning system
in the recirculated air position pro‐
vides maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to be‐
come stale.
• During cooling operation, you may oc‐
casionally notice a misty air flow be‐
cause of rapid cooling and humid air
intake. This is a normal system oper‐
ation characteristic.
