2019 NISSAN TITAN heater

2. Turn thefan speed control dial to
the desired position.
When the
orpositions are se-
lected, the air conditioner automatically
turns on if the outside temperature is more
than 36°F (2°C). The air conditioning system
will continue to operate until the
fan
speed control dial is turned to OFF, the air
conditioner is turned OFF, or the vehicle is
shut off. If a position other than the
front defrost air flow button is selected, the
A/C compressor will not turn off even if the
user had selected A/C off prior to entering
defrost. In
front defrost orfoot
defrost the indicator light on the A/C but-
ton will not turn on if the user had selected
A/C off. Turning off the air conditioning via
the A/C button is not allowed in this mode.
If the A/C button indicator was on when
entering this mode, and the A/C button is
selected in this mode, the A/C button indi-
cator will turn off, but the A/C compressor
will still be automatically enabled. This de-
humidifies the air which helps defog the
windshield. The
mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment to fur-
ther improve the defogging performance. 3. Turn the temperature control dial to
the desired position.
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.

WARNING
∙ The air conditioner cooling function operates 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 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 re-
circulation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.

∙ The temperature of the passenger compartment will be maintained auto-
matically. Air flow distribution, fan speed
and A/C on/off are also controlled auto-
matically. The A/C button indicator will
remain in the last user setting. Under
this condition, the indicator light on the
A/C button indicator will not turn on if
the user had not selected the A/C but-
ton off. Turning off the air conditioning
via the A/C button is not allowed in this
mode. If the A/C button indicator was
on when entering this mode, and the
A/C button is selected in this mode, the
A/C button indicator will turn off, but the

of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steering
maneuvers.
∙ Do not use the cruise control (if so equipped) on slippery roads.
∙ Snow can trap dangerous exhaust gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
∙ Engine block heaters should be used when the outside temperature is 0°F
(-17°C) or lower.
∙ Engine block heaters run continuously while plugged into the correct voltage
electrical outlet.
WARNING
∙Do not use your engine block heater
with an ungrounded electrical system
or a 2-pronged adapter. You can be se-
riously injured by an electrical shock if
you use an ungrounded connection.
∙ Disconnect and properly store the en-gine block heater cord before starting
the engine. Damage to the cord could
result in an electrical shock and can
cause serious injury.
∙ Use a heavy-duty 3-wire, 3-pronged extension cord rated for at least 10 A.
Plug the extension cord into a Ground
Fault Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure to
use the proper extension cord or a
grounded outlet can result in a fire or
electrical shock and cause serious
personal injury. To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged exten-
sion cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2–4 hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.

CAUTION
Use of the engine block heater when
parked with the front of the vehicle
higher than the rear (5 degrees or more)
may cause the engine block heater to
become damaged and/or inoperative.
Starting and driving5-71

WARNING
Always follow the instructions below.
Failure to do so could result in damage
to the charging system and cause per-
sonal injury.1. If the booster battery is in another ve- hicle, position the two vehicles to bring
their batteries near each other.
Do not allow the two vehicles to
touch. 2. Apply the parking brake. Move the shif t
lever to P (Park). Switch off all unneces-
sary electrical systems (lights, heater,
air conditioner, etc.).
3. Place the ignition switch in the LOCK position.
4. Ensure the vent caps are level and tight.
5. Connect the jumper cables in the se- quence illustrated (
A,B,C,D).
CAUTION
∙ Always connect positive () to posi-tive ( ) and negative () to body
ground (for example, strut mounting
bolt, engine lif t bracket, etc.) — not to
the battery.
∙ Make sure the jumper cables do not touch moving parts in the engine
compartment and that the cable
clamps do not contact any other
metal.
6. Start the engine of the booster vehicle and let it run for a few minutes.
7. Keep the engine speed of the booster vehicle at about 2,000 rpm and start the
engine of the vehicle being jump
started.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, place the ig-
nition switch in the OFF position and
wait 3 to 4 seconds before trying again.

LCE2223
In case of emergency6-15

Do not attempt to start the engine by
pushing.
CAUTION
∙ Automatic transmission models can-not be push-started or tow-started.
Attempting to do so may cause trans-
mission damage.
∙ Three way catalyst equipped models should not be started by pushing
since the three way catalyst may be
damaged.
∙ Never try to start the vehicle by tow- ing it; when the engine starts, the for-
ward surge could cause the vehicle to
collide with the tow vehicle.
WARNING
∙ Do not continue to drive if your vehicleoverheats. Doing so could cause en-
gine damage or a vehicle fire.
∙ To avoid the danger of being scalded, never remove the radiator or coolant
reservoir cap while the engine is still
hot. When the radiator or coolant res-
ervoir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
∙ Do not open the hood if steam is com- ing out.
If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc. take the
following steps: 1. Move the vehicle safely off the road, ap- ply the parking brake and move the
shif t lever to P (Park).
Do not stop the engine.
2. Turn off the air conditioner. Open all the windows, move the heater or air condi-
tioner temperature control to maxi-
mum hot and fan control to high
speed. 3. If engine overheating is caused by
climbing a long hill on a hot day, run the
engine at a fast idle (approximately
1,500 rpm) until the temperature gauge
indication returns to normal.
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 fur-
ther 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 getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling
fan is running. The radiator hoses and
radiator should not leak water. If cool-
ant is leaking, the water pump belt is
missing or loose, or the cooling fan
does not run, stop the engine.
