2021 NISSAN ARMADA cooling

WARNING
.The air conditioner cooling func-
tion operates only when the en-
gine is running.
. Do not leave children or adults
who would normally require the
support of others alone in your
vehicle. Pets should not be left
alone either. On hot, sunny days,
temperatures in a closed vehicle
could quickly become high en-
ough 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 interior air to become stale
and the windows to fog up.
. Do not adjust the heating and air
conditioning controls while driv-
ing so that full attention may be
given to vehicle operation.
Start the engine and operate the heater
and air conditioner system.
NOTE:
. Odors from inside and outside the
vehicle can build up in the air condi-
tioner unit. Odor can enter the pas-
senger compartment through the vents.
. When parking, set the heater and air
conditioner controls to turn off air
recirculation to allow fresh air into
the passenger compartment. This
should help reduce odors inside the
vehicle.

5. To stop the engine, shift the shift lever to the P (Park) position and push the
ignition switch to the OFF position.
In preparation for the next engine start,
the engine may have a slightly delayed
shutoff after placing the ignition switch in
the OFF position, depending on the driv-
ing conditions.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start condi-
tions such as:
1. Installation or extended use of elec-
tronic accessories that consume
battery power when the engine is
not running (Phone chargers, GPS,
DVD players, etc.)
2. Vehicle is not driven regularly and/
or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the remote engine
start function require the ignition switch
to be placed in the ON position before the
shift lever can be moved from the P (Park)
position. To place the ignition switch in the ON position, perform the following
steps:
1. Make sure that the Intelligent Key is
on you.
2. Firmly depress the brake pedal.
3. Push the ignition switch once to the ON position.
For additional information about the
remote engine start function, see “Re-
mote engine start” (P.3-19).
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 posi-
tion.
. 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 condi-
tions, vehicle speed will decrease. Vehicle
speed can be controlled with the accel-
erator pedal, but the vehicle may not
accelerate at the desired speed. The
transmission will downshift or upshift as
it reaches prescribed shift points. You can
also shift 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.

DRIVING THE VEHICLE

5-18Starting and driving
If:
1. The engine coolant temperature is notreduced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning light
illuminates or engine coolant
temperature gauge does not return
to the normal range from the H
position, this may indicate a malfunc-
tion. Move the vehicle off the road to a
safe area and allow the engine to cool.
If after checking the oil and coolant,
the
remains on or engine coolant
temperature does not return to the
normal range, do not continue to
drive. It is recommended you contact
a NISSAN dealer.
The Malfunction Indicator Light (MIL)
may also come ON. You do not need to
have your vehicle towed, unless it re-
mains on, but have it inspected soon. It is
recommended you contact a NISSAN
dealer for this service. See “Warning lights,
indicator lights and audible reminders”
(P.2-10).
WARNING
Overheating can result in reduced
engine power and vehicle speed.
The reduced speed may be lower
than other traffic, which could in-
crease the chance of a collision. Be
especially careful when driving. If the
vehicle cannot maintain a safe driv-
ing speed, pull to the side of the road
in a safe area. Allow the engine to
cool and return to normal operation.
See “If your vehicle overheats” (P.6-
14).
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 covered by warranty. Turn off the
engine as soon as it is safe to do so.
AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehi-
cle is electronically controlled by a trans-
mission control module to produce
maximum efficiency and smooth opera-
tion.
Shown on the following pages are the
recommended operating procedures for
this transmission. Follow these proce-
dures for maximum vehicle performance
and driving enjoyment.
Starting the vehicle
After starting the engine, fully depress the
foot brake pedal and push the shift lever
button before shifting the shift lever to
the R (Reverse), N (Neutral), D (Drive) or
Manual shift mode position. Be sure the
vehicle is fully stopped before attempting
to shift the shift lever.
This automatic transmission model is
designed so that the foot brake pedal
must be depressed before shifting from
P (Park) to any drive position while the
ignition switch position is ON.
The shift lever cannot be moved out of
the P (Park) position and into any of the
other gear positions if the ignition
switch is pushed to the LOCK, OFF or
ACC position.

CAUTION
During the first 1,200 miles (2,000
km), follow these recommendations
to obtain maximum engine perfor-
mance and ensure the future relia-
bility and economy of your new
vehicle.
Failure to follow these recommenda-
tions may result in shortened engine
life and reduced engine perfor-
mance.
. Avoid driving for long periods at con-
stant speed, either fast or slow. Do not
run the engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possi-
ble.
. Do not tow a trailer for the first 500
miles (805 km). Follow these easy-to-use Fuel Efficient
Driving Tips to help you achieve the most
fuel economy from your vehicle.
1. Use smooth accelerator and brake
pedal application.
.Avoid rapid starts and stops..Use smooth, gentle accelerator andbrake application whenever possi-
ble.
.Maintain constant speed whilecommuting and coast whenever
possible.
2. Maintain constant speed.
.Look ahead to try and anticipate and minimize stops.
.Synchronizing your speed with traf-fic lights allows you to reduce your
number of stops.
.Maintaining a steady speed canminimize red light stops and im-
prove fuel efficiency.
3. Use air conditioning (A/C) at higher vehicle speeds.
.Below 40 MPH (64 km/h), it is moreefficient 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 aerody-
namic drag.
.Recirculating the cool air in thecabin when the A/C is on reduces
cooling load.
4. Drive at economical speeds and dis- tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h)
(where legally allowed) can improve
fuel efficiency due to reduced aero-
dynamic drag.
.Maintaining a safe following dis-tance behind other vehicles re-
duces unnecessary braking.
.Safely monitoring traffic to antici- pate changes in speed permits
reduced braking and smooth accel-
eration changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady
speed.
.Cruise control is particularly effec-tive 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.

VEHICLE DYNAMIC CONTROL (VDC)
OFF SWITCH
The vehicle should be driven with the
Vehicle Dynamic Control (VDC) system ON
for most driving conditions.
When the vehicle is stuck in mud or snow,
the VDC system reduces the engine out-
put to reduce wheel spin. The engine
speed will be reduced even if the accel-
erator is depressed to the floor. If max-
imum engine power is needed to free a
stuck vehicle, turn the VDC system off.
To turn off the Vehicle Dynamic Control
(VDC) system, push the VDC OFF switch.
The VDC off indicator light
will
illuminate. Push the VDC OFF switch again or restart
the engine to turn ON the system.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing,
apply deicer through the key hole. If the
lock becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check antifreeze to assure
proper winter protection. For additional
information, see “Engine cooling system”
(P.8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P.8-11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).
COLD WEATHER DRIVING

6-12In case of emergency
To start your engine with a booster
battery, the instructions and precautions
below must be followed.
WARNING
.If done incorrectly, jump starting
can lead to a battery explosion,
resulting in severe injury or
death. It could also damage your
vehicle.
. Explosive hydrogen gas is always
present in the vicinity of the
battery. Keep all sparks and
flames away from the battery.
. Do not allow battery fluid to come
into contact with eyes, skin,
clothing or painted surfaces. Bat-
tery fluid is a corrosive sulphuric
acid solution which can cause
severe burns. If the fluid should
come into contact with anything,
immediately flush the contacted
area with water.
. Keep the battery out of the reach
of children.
. The booster battery must be
rated at 12 volts. Use of an im-
properly rated battery can da-
mage your vehicle. .
Whenever working on or near a
battery, always wear suitable eye
protectors (for example, goggles
or industrial safety spectacles)
and remove rings, metal bands,
or any other jewelry. Do not lean
over the battery when jump start-
ing.
. Do not attempt to jump start a
frozen battery. It could explode
and cause serious injury.
. Your vehicle has an automatic
engine cooling fan. It could come
on at any time. Keep hands and
other objects away from it.
