overheating NISSAN TITAN 2005 1.G Owners Manual

ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant tem-
perature 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:
cThe engine coolant temperature gauge will
move toward the H position.
cEngine power may be reduced.
cThe air conditioning cooling function may be
automatically turned OFF for a short time
(the blower will continue to operate) .
Engine power and, under some conditions, ve-
hicle speed will decrease. Vehicle speed can be
controlled with the accelerator 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 accelerator pedal, and air
conditioning cooling function will automatically
be turned back ON.If:
1. The engine coolant temperature is not re-
duced.
2. The air conditioning cooling function does
not turn back ON.
3. The engine oil pressure warning/engine
coolant temperature high indicator
il-
luminates, this may indicate a malfunction.
Move the vehicle off the road in a safe area
and allow the engine to cool. If after check-
ing the oil and coolant, the
remains
on, do not continue to drive and call a
NISSAN dealer.
The malfunction indicator lamp may also come
ON. Ifonlyit remains on, you do not need to have
your vehicle towed, but have it inspected soon by
a NISSAN dealer. See “Malfunction indicator
lamp” in the “Warning and indicator lights” sec-
tion of this manual.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
Pull to the side of the road to a safe area.
Allow the engine to cool and return to
normal operation. See “If your vehicle
overheats” in the “In case of emergency”
section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.

cHEADED DOWNHILL WITH CURB:sA
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
cHEADED UPHILL WITH CURB:
sB
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
cHEADED UPHILL OR DOWNHILL, NO
CURB:
sC
Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter of the road if it moves.
4. Turn the ignition key to the LOCK position
and remove the key.The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and at low speeds.
WARNING
If the engine is not running or is turned off
while driving, the power assist for the
steering will not work. Steering will be
much harder to operate.The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brakes and pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift 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.

If the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.
WARNING
cThe anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.
cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.cWhen installing a spare tire, make sure
it is the proper size and type as speci-
fied on the Tire and Loading Informa-
tion label. For tire placard location in-
formation, refer to “Tire and Loading
Information label” in the “Technical and
consumer information” section of this
manual.
cRefer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.cABLS is a form of traction control using
sensors from the Anti-lock Brake System
(ABS) to transfer power from a slipping drive
wheel to a wheel with more traction. The
ABLS system applies braking to the slipping
wheel, which helps redirect power to an-
other wheel.
cOn 4WD models the ABLS system operates
in both 4H and 4LO modes. On 2WD ve-
hicles, the ABLS system operates on the
drive axle only.
cThe ABLS system is always ON unless the
system detects brake pad overheating. If
high brake pad temperature is detected, it
will turn OFF, but normal brake function will
continue. ABLS will function even when the
VDC system (if so equipped) is turned OFF.
WARNING
The ABLS system provides increased trac-
tion, but will not prevent accidents due to
abrupt steering operation or by careless
driving or dangerous driving practices.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces, and always drive
carefully.

CAUTION
Automatic transmission models cannot
be push-started or tow-started. Attempt-
ing to do so may cause transmission
damage.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo 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 reser-
voir cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
cDo not open the hood if steam is com-
ing out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading and
the illumination of the engine oil pressure/engine
coolant temperature high indicator light) , 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, apply
the parking brake and move the shift lever to
P (Park) .
Do not stop the engine.
2. Turn off the air conditioner. Open all the
windows, move the heater or air conditioner
temperature control to maximum hot and fan
control to high speed.3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, stand clear to prevent getting
burned.
5. 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 coolant is leaking,
the water pump belt is missing or loose, or
the cooling fan does not run, stop the en-
gine.
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 when the coolant
temperature is high.

If the cooling system frequently requires
coolant, have it checked by a NISSAN
dealer.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheating.
WARNING
cTo avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
cNever remove the radiator or engine
coolant reservoir cap when the engine
is hot. Serious burns could be caused
by high pressure fluid escaping from
the radiator.
cAvoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner
as soon as possible.
cKeep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and apply
the parking brake.
2. Start the engine and let it idle until it reaches
operating temperature.
3. Turn off the engine.Wait more than 10
minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re-
insert it all the way.5. Remove the dipstick again and check the oil
level. It should be between the H (High) and
L (Low) markssB. This is the normal oper-
ating oil level range. If the oil level is below
the L (Low) mark
sA, remove the oil filler cap
and pour recommended oil through the
opening.Do not overfill
sC.
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 severity
of operating conditions.

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 se-
vere, 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, 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, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
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.
FLEXIBLE FUEL VEHICLE (FFV) FUEL
RECOMMENDATION (if so equipped)
Your vehicle is designed to use (E-85) Fuel Etha-
nol, “Regular” unleaded regular gasoline or any
percentage of the two fuels combined.
U.S. government regulations require Fuel
Ethanol dispensing pumps to have a small,
square, orange and black label with the
common abbreviation or the appropriate
percentage for that region.
CAUTION
Use of other fuels such as Fuel Methanol
may cause powertrain damage or a loss of
vehicle performance.
General information
This information is for Flexible Fuel vehicles (FFV)
only. FFV vehicles can be identified by the fuel filler
door label that states Ethanol (E-85) or Unleaded
Gasoline Only. This section only covers those sub-
jects that are unique to Flexible Fuel vehicles.
CAUTION
Only vehicles with the E-85 filler door label
can operate on E-85. Fuel system or other
damage can occur if E-85 is used in vehicles
that are not designed to run on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel etha-
nol and 15% unleaded gasoline.
WARNING
cEthanol vapors are extremely flam-
mable and could cause serious per-
sonal injury.
cNever have any smoking materials lit in
or near the vehicle when removing the
fuel filler cap or filling the tank.
cDo not use E-85 as a cleaning agent and
never use it near an open flame.
Fuel requirements
Your vehicle will operate on both unleaded regu-
lar gasoline with an octane rating of at least 87
AKI (Anti-Knock Index) number (Research oc-
tane number 91) , or E-85 fuel, or any mixture of
these two.
For the best starting and vehicle driveability re-
sults, do not continually switch between E-85
and unleaded regular gasoline. If you must switch
fuels, NISSAN recommends the following:
cdo not switch when the fuel gauge indicates
less than 1/4 full
cadd more than 5 gallons of fuel

WARNING
Overloading or improper loading of a
trailer and its cargo can adversely affect
vehicle handling, braking and perfor-
mance and may lead to accidents.
CAUTION
cDo not tow a trailer or haul a heavy load
for the first 500 miles (800 km) . Your
engine, axle or other parts could be
damaged.
cFor the first 500 miles (800 km) that you
tow a trailer, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other
parts of your vehicle wear in at the
heavier loads.
Your new vehicle was designed to be used pri-
marily to carry passengers and cargo. Remember
that towing a trailer places additional loads on
your vehicle’s engine, drive train, steering, brak-
ing and other systems.
ANissan Trailer Towing Guide (U.S. only)is
available from a NISSAN dealer. This guide in-
cludes information on trailer towing ability and the
special equipment required for proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loads
Never allow the total trailer load to exceed the
value specified in the following Towing
Load/Specification Chart found later in this sec-
tion. The total trailer load equals trailer weight
plus its cargo weight.
cWhen towing a trailer load of 1,000 lbs.
(454 kg) or more, trailers with a brake sys-
tem MUST be used.
The maximum GCWR (Gross Combined Weight
Rating) should not exceed the value specified in
the following Towing Load/ Specification Chart.
The GCWR equals the combined weight of the
towing vehicle (including passengers and cargo)
plus the total trailer load. Towing loads greater
than these or using improper towing equipment
could adversely affect vehicle handling, braking
and performance.
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 appro-
priate for level highway driving may have to be
reduced on very steep grades or in low traction
situations (for example, on slippery boat ramps) .
Temperature conditions can also affect towing.
For example, towing a heavy trailer in high outsidetemperatures 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 automati-
cally 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 engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
Pull to the side of the road to a safe area.
Allow the engine to cool and return to
normal operation. See “If your vehicle
overheats” in the “In case of emergency”
section of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures are not covered by
NISSAN warranties. A NISSAN Trailer
Towing Guide (U.S. only) containing infor-
mation on trailer towing ability and the
special equipment required may be ob-
tained from a NISSAN dealer.

4. Peel off the tape and connect the jumper
harness to the connector
s2.
5. Release the parking brake.
6. Install the aftermarket electric trailer brake
controller according to the manufacturer’s
instructions.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if it
has an abnormal nose-up or nose-down
condition; check for improper tongue load,
overload, worn suspension or other possible
causes of either condition.cAlways secure items in the trailer to prevent
load shift while driving.
cLoad the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.
cCheck your hitch, trailer tire pressure, ve-
hicle tire pressure, trailer light operation, and
trailer wheel lug nuts every time you attach a
trailer to the vehicle.
cBe certain your rearview mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability and braking perfor-
mance will be somewhat different than under
normal driving conditions.
cAlways secure items in the trailer to prevent
load shift while driving.
cAvoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.cWhen backing up, hold the bottom of the
steering wheel with one hand. Move your
hand in the direction in which you want the
trailer to go. Make small corrections and
back up slowly. If possible, have someone
guide you when you are backing up.
cAlways block the wheels on both vehicle and
trailer when parking. Parking on a slope is
not recommended; however, if you must do
so, first block the wheels and apply the park-
ing brake, and then move the transmission
shift selector lever into the P (Park) position.
If you move the shift selector lever to the P
(Park) position before blocking the wheels
and applying the parking brake, transmission
damage could occur.
cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When going up a long grade, downshift the
transmission to a lower gear and reduce
speed to reduce chances of engine over-
loading and/or overheating. However, for
long steep grades, do not stay in 1st gear
when driving above 35 MPH (56 km/h) or
2nd gear when driving above 58 MPH (93
km/h) .
