2018 NISSAN TITAN coolant temperature

∙ Do not use the cruise control (if soequipped) 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 0ºF
(-17ºC) or lower.
∙ Engine block heaters run continuously while plugged into the correct voltage
electrical outlet.
WARNING
∙ Do not use your engine block heaterwith an ungrounded electrical system
or a 2-pronged adapter. You can be
seriously 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.
NOTE:
When using the engine block heater (if so
equipped) on an Applied Vehicle (engine
block heater is plugged in): ∙ Vehicle should be parked on a level
surface.
Or
∙ If a level surface is not available, the
vehicle should be parked with the
front of the truck lower than the rear
(nose down).
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

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.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
In case of emergency6-15

Engine coolant must be disposed of prop-
erly. Check your local regulations.
For additional information on changing the
Cummins 5.0L engine coolant, refer to the
“Titan Diesel Owner’s Manual”.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
15 minutes for the oil to drain back
into the oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check
the oil level. It should be between the H
(High) and L (Low) marksB. This is the
normal operating oil level range. If the
oil level is below the L (Low) mark
A,
remove the oil filler cap and pour rec-
ommended oil through the opening.
Do not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the sever-
ity of operating conditions.

∙ While going downhill, the weight of thetrailer pushing on the tow vehicle may
decrease overall stability. Therefore, to
maintain adequate control, reduce your
speed and shif t to a lower gear. Avoid
long or repeated use of the brakes
when descending a hill, as this reduces
their effectiveness and could cause
overheating. Shif ting to a lower gear in-
stead provides “engine braking” and re-
duces the need to brake as frequently.
∙ If the engine coolant temperature rises to a high temperature, refer to “If your
vehicle overheats” in the “In case of
emergency” section of this owner’s
manual.
∙ Trailer towing requires more fuel than normal circumstances.
∙ Avoid towing a trailer for your vehicle’s first 500 miles (805 km).
∙ For the first 500 miles (805 km) that you do tow, do not drive over 50 mph
(80 km/h).
∙ Have your vehicle serviced more of ten than at intervals specified. For addi-
tional information, refer to “Mainte-
nance schedules” in the “Maintenance
and schedule” section of this manual. ∙ When making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
∙ Crosswinds and rough roads will ad- versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be pre-
pared for possible changes in cross-
winds that could affect vehicle han-
dling.
Trailer Sway Assist :
To minimize trailer sway, your vehicle may
apply braking to individual wheels based
on input from your vehicle sensors and ve-
hicle speed. Trailer sway control is a func-
tion of the Vehicle Dynamic Control (VDC)
system and is active when the VDC func-
tion is enabled.
CAUTION
If the VDC-OFF switch is on (meaning
VDC system OFF), the Trailer Sway As-
sist is also disabled When Trailer Sway Assist is in operation, the
VDC warning light blinks. When vehicle con-
trol is regained, VDC warning light will turn
OFF.
For additional information about the VDC
system, refer to “Vehicle Dynamic Control
(VDC) OFF switch” in the “Instruments and
controls” section and “Vehicle Dynamic
Control (VDC) system” in the “Starting and
driving” section of this manual.
If Trailer Sway Assist activates, do the fol-
lowing:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer
as straight ahead as the road condi-
tions allow. This combination will help
stabilize the vehicle
CAUTION
Do not try to correct trailer sway by
steering or applying the brakes.
2. When the trailer sway stops, gently ap- ply the brakes and pull to the side of the
road in a safe area.
3. Try to rearrange the trailer load so it is balanced. For additional information,
refer to “Pre-towing tips” in this section.
