2006 NISSAN SENTRA engine overheat

If any driveability problems such as engine stall-
ing and difficult hot-starting are experienced after
using oxygenate-blend fuels, immediately
change to a non-oxygenate fuel or a fuel with a
low blend of MTBE.
Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
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 vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square, orange
and black label with the common abbreviation or
the appropriate percentage for that region.
Aftermarket fuel additives
NISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel injec-
tor 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 solvents 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 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.
CAUTION
cYour vehicle is not designed to run on
E-85 fuel. Using E-85 fuel in a vehicle
not specifically designed for E-85 fuel
can damage fuel system components
and is not covered by the NISSAN new
vehicle limited warranty.
cE-85 is a mixture of approximately 85%
fuel ethanol and 15% unleaded
gasoline.
cU.S. government regulations require
ethanol dispensing pumps to be identi-
fied by a small, square, orange and
black label with the common abbrevia-
tion or the appropriate percentage for
that region.

WARNING
Never connect a trailer brake system di-
rectly to the vehicle brake system.
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. Some states or provinces have spe-
cific speed limits for vehicles that are towing
trailers. Obey the local speed limits.
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, and if your vehicle is equipped with an
automatic transmission, first block the
wheels and apply the parking brake, andthen move the transmission shift selector
lever into the P (Park) position. If you move
the shift selector lever to the P (Park) posi-
tion 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.
cIf the engine coolant rises to an extremely
high temperature when the air conditioner
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan
control to high and setting the temperature
control to the HOT position.
cTrailer towing requires more fuel than normal
circumstances.
cAvoid towing a trailer for your vehicle’s first
500 miles (805 km) .
cFor the first 500 miles that you do tow, do
not drive over 50 MPH (80 km/h) .

cHave your vehicle serviced more often than
at intervals specified in the recommended
Maintenance Schedule in the “NISSAN Ser-
vice and Maintenance Guide”.
cWhen 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.
cCrosswinds and rough roads will adversely
affect vehicle/trailer handling, possibly caus-
ing vehicle sway. When being passed by
larger vehicles, be prepared for possible
changes in crosswinds that could affect ve-
hicle handling. If swaying does occur, firmly
grip the steering wheel, steer straight ahead,
and immediately (but gradually) reduce ve-
hicle speed. This combination will help sta-
bilize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires con-
siderably more distance than normal pass-
ing. Remember, the length of the trailer must
also pass the other vehicle before you can
safely change lanes.
cTo maintain engine braking efficiency and
electrical charging performance, do not use
5th gear (manual transmission) or overdrive
(automatic transmission) .cAvoid holding the brake pedal down too long
or too frequently. This could cause the
brakes to overheat, resulting in reduced
braking efficiency.
cIncrease your following distance to allow for
greater stopping distances while towing a
trailer. Anticipate stops and brake gradually.
cDo not use cruise control while towing a
trailer.
cCheck your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
cWhen stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
When towing a trailer, transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
cFailure to follow these guidelines can
result in severe transmission damage.
cWhenever flat towing your vehicle, al-
ways tow forward, never backward.
cDO NOT tow any automatic transmis-
sion vehicle with all four wheels on the
ground (flat towing) . Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
cFor emergency towing procedures refer
to “Towing recommended by NISSAN”
in the “In case of emergency” section of
this manual.
Automatic Transmission
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
Manual Transmission
cAlways tow with the manual transmission in
Neutral.
