2021 NISSAN ROGUE engine coolant

air conditioner automatically turns on if
the outside temperature is more than
slightly above freezing. This dehumidifies
the air which helps defog the windshield.
The air recirculation mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment to
further improve the defogging perfor-
mance.
The air conditioner is always turned on in
the
ormode, regardless of
whether the indicator light is on or off.
NOTE:
. The air conditioner system should
be operated for approximately 10
minutes at least once a month. This
helps prevent damage to the air
conditioner system due to the lack
of lubrication.
. A visible mist may be seen coming
from the ventilators in hot, humid
conditions as the air is cooled ra-
pidly. This does not indicate a mal-
function.
. If the engine coolant temperature
becomes too high, the air recircula-
tion mode will be activated and the
indicator light will turn on automa-
tically.
. If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn the air conditioner off. (See “If your
vehicle overheats” (P.6-13).)

OPERATING TIPS (for automatic air
conditioner)
When the engine coolant temperature
and outside air temperature are low, the
air flow from the foot outlets may be
limited when in the automatic mode.
However, this is not a malfunction. After
the coolant temperature warms up, air
flow from the foot outlets will operate
normally.
For rear temperature control (if so
equipped):
.The purpose of the rear temperature
control is to vary the temperature of
the rear airflow.
. The amount of airflow to the rear
ventilators is primarily controlled by
the front passenger’s blower and
mode settings.
. The amount of airflow to the rear
ventilators is also affected by the rear
temperature setting. Higher rear tem-
perature settings have lower airflow
amounts than cooler temperature
settings. This condition ensures better
comfort to the head and face area,
while primary heating for the rear
passenger seats is provided through
the foot outlets.

SERVICING AIR CONDITIONER
WARNING
The air conditioner system contains
refrigerant under high pressure. To
avoid personal injury, any air condi-
tioner service should be done only by
an experienced technician with the
proper equipment.
The air conditioner system in your vehicle
is charged with a refrigerant designed
with the environment in mind.
This refrigerant will not harm the
earth’s ozone layer. However, it may
contribute in a small part to global
warming.
Special charging equipment and lubricant
are required when servicing your vehicle’s
air conditioner. Using improper refriger-
ants or lubricants will cause severe da-
mage to the air conditioner system. (See
“Air conditioning system refrigerant and
lubricant recommendations” (P.10-7).)

engine will start.
After step 3 is performed, when the
ignition switch is pushed without depres-
sing the brake pedal, the ignition switch
position will change to ON.
NOTE:
. When the ignition switch is pushed
to the ON position or the engine is
started by the above procedures, the
“Key Battery Low” warning appears
(on the vehicle information display)
even if the Intelligent Key is inside
the vehicle. This is not a malfunction.
To turn off the warning, touch the
ignition switch with the Intelligent
Key again.
. If the “Key Battery Low” warning
appears, replace the battery as soon
as possible. (See “Intelligent Key
battery replacement” (P.8-20).) .
Make sure the area around the vehicle
is clear.
. Check fluid levels such as engine oil,
coolant, brake fluid, and window
washer fluid as frequently as possible,
or at least whenever you refuel.
. Check that all windows and lights are
clean.
. Visually inspect tires for their appear-
ance and condition. Also check tires
for proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints/headrests.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is placed in
the ON position. (See “Warning lights,
indicator lights and audible remin-
ders” (P.2-13).) 1. Apply the parking brake.
2. Confirm that the vehicle is in the P
(Park) position.

SYSTEM MAINTENANCE
The sonar sensorsare located on the
rear bumper.
. Always keep the area near the sonar
sensors clean.
. If the sonar sensors are dirty, wipe
them off with a soft cloth while being
careful to not damage them.
. The sonar sensors may be blocked by
temporary ambient conditions such
as splashing water, mist or fog. The
blocked condition may also be caused
by objects such as ice, frost or dirt
obstructing the sonar sensors. Check
for and remove objects obstructing
the area around the sonar sensors. .
Do not subject the area around the
sonar sensors to strong impact. Also,
do not remove or disassemble the
sonar sensors. If the sonar sensors
and peripheral areas are deformed in
an accident, etc., have the sonar
sensors checked. It is recommended
that you visit a NISSAN dealer for this
service.
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint on
the sonar sensors and their surround-
ing areas. This may cause a malfunc-
tion or improper operation.
. When washing the vehicle using a
high-pressure washer, do not apply
direct washer pressure on the sonar
sensors. This may cause a malfunction
of the sonar sensors.
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.
ANTI-FREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check the anti-freeze 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
anti-freeze, drain the cooling system,
including the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).
COLD WEATHER DRIVING

CAUTION
Do not keep the starter motor en-
gaged for more than 10 seconds. If
the engine does not start right away,
place the ignition switch in the OFF
position and wait 10 seconds before
trying again.
8. After starting your engine, carefully disconnect the negative cable and
then the positive cable (
???). Do not attempt to start the engine by
pushing.
CAUTION
.
Continuously Variable Transmis-
sion (CVT) models cannot be
push-started or tow-started. At-
tempting to do so may cause
transmission damage.
. Three-way catalyst equipped
models should not be started by
pushing since the three way cat-
alyst may be damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause
the vehicle to collide with the
tow vehicle.
WARNING
.Never continue driving if your
vehicle overheats. Doing so could
cause a vehicle fire.
. Never open the hood if steam is
coming out.
. Never remove the radiator or
coolant reservoir cap while the
engine is hot. If the radiator or
coolant reservoir cap is removed
when the engine is hot, pressur-
ized hot water will spurt out and
possibly cause burning, scalding
or serious injury.
. If steam or coolant is coming
from the engine, stand clear of
the vehicle to prevent getting
burned.
. The engine cooling fan will start
at anytime when the coolant
temperature exceeds preset de-
grees.
. Be careful not to allow your
hands, hair, jewelry or clothing
to come into contact with, or to
get caught in the cooling fan or
drive belts.

4. Get out of the vehicle. Look and listen for steam or coolant escaping from
the radiator before opening the hood.
(If steam or coolant is escaping, turn
off the engine.) Do not open the hood
further until no steam or coolant can
be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent get-
ting burned.
6. Visually check the drive belt for da- mage or looseness. Also check if the
cooling fan is running. The radiator
hoses and radiator should not leak
water. If coolant is leaking or the
cooling fan does not run, stop the
engine.
WARNING
Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or get caught in, engine
belts or the engine cooling fan. The
engine cooling fan can start at any
time. 7. After the engine cools down, check
the coolant level in the reservoir with
the engine running. Add coolant to
the reservoir if necessary. Have your
vehicle repaired. It is recommended
you visit a NISSAN dealer for this

When performing any inspection or main-
tenance work on your vehicle, always
take care to prevent serious accidental
injury to yourself or damage to the
vehicle. The following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
Push the park button to shift to
the P (Park) position.
. Be sure the ignition switch is in
the OFF position when perform-
ing any parts replacement or
repairs.
. If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle. .
Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed space such as a garage,
be sure there is proper ventilation
for exhaust gases to escape.
. Never get under the vehicle while
it is supported only by a jack. If it
is necessary to work under the
vehicle, support it with safety
stands.
. Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
. Keep smoking materials, flame
and sparks away from fuel and
the battery.
. On gasoline engine models with
the Multiport Fuel Injection (MFI)
system, the fuel filter and fuel
lines should be serviced because
the fuel lines are under high
pressure even when the engine
is turned off. It is recommended
that you visit a NISSAN dealer for
this service. .
Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition
switch is in the OFF position and
the engine is not running. To
avoid injury, always disconnect
the negative battery cable before
working near the fan.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, and
engine coolant and/or other ve-
hicle fluids can damage the en-
vironment. Always conform to
local regulations for disposal of
vehicle fluid.
. Never leave the engine or the CVT
related component harnesses
disconnected while the ignition
switch is in the ON position.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
