2018 NISSAN NV PASSENGER VAN cooling

The air flow from the floor vents located
beneath the second and third row passen-
ger’s seats cannot be adjusted or closed.
These vents are only operational when the
rear fan speed control dial is at a setting
other than 0 and the rear temperature
control dial is at a setting other than cold.
For additional information, refer to “Rear
seat air conditioner” in this section.
WARNING
∙ The air conditioner cooling functionoperates only when the engine is
running.
∙ Do not leave children or adults who would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves or others through inadvertent
operation of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
∙ Do not use the recirculation mode for long periods as it may cause the inte-
rior air to become stale and the win-
dows to fog up. NOTE:
∙ Odors from inside and outside the ve- hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
∙ When parking, set the heater and air conditioner controls to turn off air recir-
culation to allow fresh air into the pas-
senger compartment. This should help
reduce odors inside the vehicle.

Operating tips
∙ Keep the windows closed while the airconditioner is in operation.
∙ Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to
vent hot air from the passenger com-
partment. Then, close the windows.
This allows the air conditioner to cool
the interior more quickly. ∙
The air conditioning system should
be operated for approximately
10 minutes at least once a month.
This helps prevent damage to the
system due to lack of lubrication.
∙ A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
∙ If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, refer to “If your vehicle
overheats” in the “In case of emer-
gency ” section of this manual.
