engine overheat NISSAN TITAN 2020 Owner´s Manual

The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance
and could result in loss of vehicle control.
WARNING
• While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshif ting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an
accident.
• If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake
pedal to heat up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if
you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.

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.
8. Af ter starting the engine, carefully dis- connect the negative cable and then
the positive cable. 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
transmission 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 ve-
hicle overheats. Doing so could cause
engine 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
coming 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 maximum
hot and fan control to high speed.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
6-12In case of emergency

3. If engine overheating is caused byclimbing a long hill on a hot day, run the
engine at a fast idle (approximately 1,500
rpm) until the temperature gauge indi-
cation returns to normal.
4. Get out of the vehicle. Look and listen for steam or coolant escaping from the ra-
diator before opening the hood. If steam
or coolant is escaping, turn off the en-
gine. 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 getting
burned.
6. Visually check drive belts for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing
or loose, 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 con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time.
7. Af ter the engine cools down, check the coolant level in the engine coolant reser-
voir tank with the engine running. Add
coolant to the engine coolant reservoir
tank if necessary. It is recommended
that you visit a NISSAN dealer for this
service. When towing your vehicle, all jurisdictional
and local regulations for towing must be
followed. Incorrect towing equipment
could damage your vehicle. Towing in-
structions are available from a NISSAN
dealer. Local service operators are gener-
ally familiar with the applicable laws and
procedures for towing. To assure proper
towing and to prevent accidental damage
to your vehicle, NISSAN recommends hav-
ing a service operator tow your vehicle. It is
advisable to have the service operator
carefully read the following precautions:
WARNING
• Never ride in a vehicle that is being
towed.
• Never get under your vehicle af ter it
has been lif ted by a tow truck.
• If your vehicle has front recovery
hooks as original factory equipment,
do not remove or modif y them. If it
was not equipped with front recov-
ery hooks, do not install them. Either
action could affect proper operation
of the front air bag system resulting
in injury or death.
TOWING YOUR VEHICLE
In case of emergency6-13

The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round antifreeze and coolant protec-
tion. The antifreeze solution contains rust
and corrosion inhibitors. Additional engine
cooling system additives are not neces-
sary.
WARNING
• Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator
cool down. Serious burns could be
caused by high pressure fluid escap-
ing from the radiator. For additional
information on precautions, refer to
“If your vehicle overheats” found in
the “In case of emergency ” section of
this manual.
• The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, it is recommended
that you use only a Genuine NISSAN
radiator cap.
CAUTION
• Never use any cooling system addi-
tives such as radiator sealer. Addi-
tives may clog the cooling system
and cause damage to the engine,
transmission and/or cooling system.
• When adding or replacing coolant, it
is recommended that you use only
Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equiva-
lent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-
diluted to provide antifreeze protec-
tion to -34° F (-37° C). If additional
freeze protection is needed due to
weather where you operate your ve-
hicle, add Genuine NISSAN Long Life
Antifreeze/Coolant (blue) concen-
trate following the directions on the
container. If an equivalent coolant
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s in-
structions to maintain minimum an-
tifreeze protection to -34° F (-37° C).
The use of other types of coolant so-
lutions other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
or equivalent may damage the en-
gine cooling system. •
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km)
or 7 years. Mixing any other type of
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue)
(or equivalent coolant), including
Genuine NISSAN Long Life
Antifreeze/Coolant (green), or the
use of non-distilled water may re-
duce the life expectancy of the
factory-fill coolant. For additional in-
formation, refer to the "Maintenance
and schedules" section of this
manual.

E–15 fuel
E-15 fuel is a mixture of approximately 15%
fuel ethanol and 85% unleaded gasoline.
E-15 can only be used in vehicles designed
to run on E-15 fuel. Do not use E-15 in your
vehicle. U.S. government regulations re-
quire fuel ethanol dispensing pumps to be
identified with small, square, orange and
black label with the common abbreviation
or the appropriate percentage for that re-
gion.
E–85 fuel
E-85 fuel is a mixture of approximately 85%
fuel ethanol and 15% unleaded gasoline.
E-85 can only be used in a Flexible Fuel
Vehicle (FFV). Do not use E-85 in your ve-
hicle. U.S. government regulations require
fuel ethanol dispensing pumps to be iden-
tified by a small, square, orange and black
label with the common abbreviation or the
appropriate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting ad-
ditive. NISSAN does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Notethat while some fuel pumps label MMT
content, not all do, so you may have to
consult your gasoline retailer for more de-
tails.
Af termarket fuel additives
NISSAN does not recommend the use of
any af termarket fuel additives (for ex-
ample, fuel injector cleaner, octane
booster, intake valve deposit removers,
etc.) which are sold commercially. Many of
these additives intended for gum, varnish
or deposit removal may contain active sol-
vents or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended can
cause persistent, heavy “spark knock.”
(“Spark knock” is a metallic rapping
noise.) If severe, this can lead to engine
damage. If you detect a persistent heavy
spark knock even when using gasoline
of the stated octane rating, or if you hear
steady spark knock while holding a
steady speed on level roads, it is recom-
mended that you have a NISSAN dealer
correct the condition. Failure to correct
the condition is misuse of the vehicle, for
which NISSAN is not responsible.
Incorrect ignition timing may result in
spark knock, af ter-run and/or overheating,
which may cause excessive fuel consump-
tion or engine damage. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not
a cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
10-6Technical and consumer information

The GCWR equals the combined weight of
the towing vehicle (including passengers
and cargo) plus the total trailer load. Tow-
ing loads greater than these or using im-
proper towing equipment could adversely
affect vehicle handling, braking and perfor-
mance.
The ability of your vehicle to tow a trailer is
not only related to the maximum trailer
loads, but also the places you plan to tow.
Tow weights appropriate for level highway
driving may have to be reduced for low
traction situations (for example, on slippery
boat ramps).Temperature conditions can also affect
towing. For example, towing a heavy trailer
in high outside temperatures on graded
roads can affect engine performance and
cause overheating. The engine protection
mode, which helps reduce the chance of
engine damage, could activate and auto-
matically decrease engine power. Vehicle
speed may decrease under high load. Plan
your trip carefully to account for trailer and
vehicle load, weather and road conditions.
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
Vehicle damage resulting from im-
proper towing procedures is not cov-
ered by NISSAN warranties.

10-34Technical and consumer information

• 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 overheat-
ing. Shif ting to a lower gear instead pro-
vides “engine braking” and reduces the
need to brake as frequently.
• If the engine coolant temperature rises to a high temperature, refer to “If your ve-
hicle overheats” in the “In case of emer-
gency” 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 additional
information, refer to “Maintenance
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 compensate 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 be-
ing passed by larger vehicles, be pre-
pared for possible changes in crosswinds
that could affect vehicle handling.
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 conditions
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 apply 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, re-
fer to “Pre-towing tips” in this section.
NOTE:
Trailer Sway Assist cannot reduce trailer
sway in all situations.
Technical and consumer information10-53

• Be careful when passing other vehicles.Passing while towing a trailer requires
considerably more distance than normal
passing. Remember, the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
• Use the Tow Mode or downshif t the transmission to a lower gear for engine
braking when driving down steep or long
hills. This will help slow the vehicle without
applying the brakes.
• Avoid holding the brake pedal down too long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
• Increase your following distance to allow for greater stopping distances while tow-
ing a trailer. Anticipate stops and brake
gradually.
• NISSAN recommends that the cruise control (if so equipped) not be used while
towing a trailer.
• While towing a trailer, do not use the fol- lowing systems (if so equipped):–– the Lane Departure Warning (LDW) sys- tem
–– the Blind Spot Warning (BSW) system
– – the Intelligent Cruise Control (ICC) sys-
tem –
– the Automatic Emergency Braking
(AEB) system
– – the Intelligent Forward Collision Warn-
ing (I-FCW) system
– – the Rear Automatic Braking (RAB) sys-
tem
– – the Moving Object Detection (MOD)
system
– – the Cross Traffic Alert system
–– the Rear Sonar system
• Some states or provinces have specific regulations and speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
• Check your hitch, trailer wiring harness connections, and trailer wheel lug nuts
af ter 50 miles (80 km) of travel and at
every break.
• When launching a boat, don't allow the water level to go over the exhaust tail
pipe or rear bumper.
• Make sure you disconnect the trailer lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, final drive gear oil
should be replaced and transmission oil/
fluid should be changed more fre-
quently. For additional information, refer
to the “Do-it-yourself ” section in this
manual.Tow mode
Using tow mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Press the TOW MODE switch to acti-
vate tow mode. The indicator light on the
TOW MODE switch illuminates when tow
mode is selected. Press the TOW MODE
switch again to turn tow mode off. Tow
mode is automatically canceled when the
ignition switch is turned off.
Tow mode includes the following features:
• Grade logic — Adjusts transmission shif ts when pulling a trailer or hauling a load up
a grade.
• Downhill Speed Control (DSC) — auto- matically downshif ts when driving down
a grade with a trailer or heavy load to help
control vehicle speed.
Driving the vehicle in the tow mode with no
trailer/load or light trailer/light load will not
cause any damage. However, fuel
economy may be reduced and the
transmission/engine driving characteris-
tics may feel unusual.
When towing a trailer, final drive gear oil
should be replaced and transmission oil/
fluid should be changed more frequently.
For additional information, refer to the
“Do-it-yourself ” section of this manual.
