cooling NISSAN NV PASSENGER VAN 2018 Owners Manual

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.

ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the
coolant temperature becomes too high
(for example, when climbing steep grades
in high temperature with heavy loads, such
as when towing a trailer). When the engine
temperature reaches a certain level:∙ The engine coolant temperature gauge will move toward the H position.
∙ Engine power may be reduced.
∙ The air conditioning cooling function may be automatically turned off for a
short time (the blower will continue to
operate).
Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator
pedal, but the vehicle may not accelerate at
the desired speed. The transmission will
downshif t or upshif t as it reaches pre-
scribed shif t points. You can also shif t
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel- erator pedal, and air conditioning cooling
function will automatically be turned back
on.
A malfunction may have occurred if:
∙ The engine coolant temperature is not reduced,
∙ The air conditioning cooling function does not turn back on, or
∙ The engine oil pressure warning light illuminates or the engine coolant tem-
perature gauge indicates an overheat-
ing condition.
If a malfunction occurs move the vehicle
off the road in a safe area and allow the
engine to cool. If the condition is still pres-
ent af ter checking the oil and coolant, do
not continue to drive. It is recommended
that you contact a NISSAN dealer.
The Malfunction Indicator Light (MIL) may
also come on. If onlyit remains on, you do
not need to have your vehicle towed, but
have it inspected soon. It is recommended
that you visit a NISSAN dealer for this ser-
vice. For additional information, refer to
“Malfunction Indicator Light (MIL)” in the “In-
struments and controls” section of this
manual.
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful when
driving. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. Allow the engine to
cool and return to normal operation. For
additional information, refer to “If your
vehicle overheats” in the “In case of
emergency ” section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
DRIVING THE VEHICLE
5-12Starting and driving

3.Use Air Conditioning (A/C) at Higher
Vehicle Speeds
∙ Below 40 mph (64 km/h), it is more efficient to open windows to cool the
vehicle due to reduced engine load.
∙ Above 40 mph (64 km/h), it is more efficient to use A/C to cool the vehicle
due to increased aerodynamic drag.
∙ Recirculating the cool air in the cabin when the A/C is on reduces cooling
load.
4. Drive at Economical Speeds and
Distances
∙ Observing the speed limit and not exceeding 60 mph (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
∙ Maintaining a safe following distance behind other vehicles reduces un-
necessary braking.
∙ Safely monitoring traffic to anticipate changes in speed permits reduced
braking and smooth acceleration
changes.
∙ Select a gear range suitable to road conditions. 5.
Use Cruise Control
∙ Using cruise control during highway driving helps maintain a steady
speed.
∙ Cruise control is particularly effective in providing fuel savings when driving
on flat terrains.
6. Plan for the Shortest Route
∙ Utilize a map or navigation system to determine the best route to save
time.
7. Avoid Idling
∙ Shutting off your engine when safe for stops exceeding 30–60 seconds
saves fuel and reduces emissions.
8.
Buy an Automated Pass for Toll Roads
∙ Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and avoid
stopping and starting. 9.
Winter Warm Up
∙ Limit idling time to minimize impact to fuel economy.
∙ Vehicles typically need no more than 30 seconds of idling at start-up to
effectively circulate the engine oil be-
fore driving.
∙ Your vehicle will reach its ideal oper- ating temperature more quickly
while driving versus idling.
10. Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem.
