2007 NISSAN MURANO engine overheat

engine stalling and hard hot starting are experi-
enced after using oxygenate-blend fuels, imme-
diately 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 fuelE-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 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispensing
pumps to be identified by a small, square, or-
ange and black label with the common abbre-
viation or the appropriate percentage for that
region.Aftermarket fuel additivesNISSAN does not recommend the use of any
aftermarket fuel additives (for example, fuel in-
jector cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for gum,
varnish or deposit removal may contain active
solvent or similar ingredients that can be harmful
to the fuel system and engine.
Octane rating tipsUsing 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 your dealer correct the condi-
tion. Failure to correct the condition is
misuse of the vehicle, for which NISSAN is
not responsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer or other competent service fa-
cility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

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

Do 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.

For 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 ve-
hicle wear in at the heavier loads.
Your new vehicle was designed to be used
primarily to carry passengers and cargo. Re-
member that towing a trailer will place additional
loads on your vehicle’s engine, drive train, steer-
ing, braking and other systems.
A NISSAN Towing Guide (U.S. only) is available
on the website at www.nissanusa.com. This
guide includes information on trailer towing ca-
pability and the special equipment required for
proper towing.
MAXIMUM LOAD LIMITS
Maximum trailer loadsNever allow the total trailer load to exceed the
value specified in the Towing Load/Specification
Chart found later in this section. The total trailer
load equals trailer weight plus its cargo weight.
When towing a trailer load of 1,000 lbs. (454
kg) or more, trailers with a brake system
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 specified or using
improper towing equipment could adversely af-
fect 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
appropriate 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 also can affect towing.
For example, towing a heavy trailer in high
outside temperatures on graded roads can af-
fect engine performance and cause overheating.
The transmission high fluid temperature protec-
tion mode, which helps reduce the chance of
transmission damage, could activate and auto-
matically decrease engine power. Vehicle speed
may decrease to 40 to 50 MPH (65 to 80 km/h)
under high load. Plan your trip carefully to ac-

count for trailer and vehicle load, weather, and
road conditions.
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. Also,
when the high temperature mode oper-
ates, vehicle speed may be gradually
reduced. The reduced speed may be
lower than other traffic, which could
increase the chance of a collision. Be
especially careful when driving. If nec-
essary, pull to the side of the road at a
safe place and allow the engine to cool
or the transmission to return to normal
operation.
CAUTION
Vehicle damage resulting from im-
proper towing procedures is not cov-
ered by NISSAN warranties.
Tongue loadKeep the tongue load between 9 to 11 percent
of the total trailer load within the maximum
tongue load limits shown in the following Towing
Load/Specifications Chart. If the tongue load
becomes excessive, rearrange cargo to allow for
proper tongue load.
Maximum gross vehicle weight/
maximum gross axle weightThe gross vehicle weight of the towing vehicle
must not exceed the gross vehicle weight rating
(GVWR) shown on the F.M.V.S.S. certification
label. The gross vehicle weight equals the com-
bined weight of the unloaded vehicle, passen-
gers, luggage, hitch, trailer tongue load and any
other optional equipment. In addition, front or
rear gross axle weight must not exceed the
gross axle weight rating (GAWR) shown on the
F.M.V.S.S. certification label.

the proper equipment and to have it
installed.
Trailer lights should comply with federal and/or
local regulations. For assistance in hooking up
trailer lights, contact a NISSAN dealer or repu-
table trailer dealer.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Pre-towing tips
Be 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 con-
dition; check for improper tongue load, over-
load, worn suspension or other possible
causes of either condition.
Always secure items in the trailer to prevent
load shifts while driving.

Load the trailer so approximately 60% of the
trailer load is in the front half and 40% is in
the back half.

Check your hitch, trailer tire pressure, vehicle
tire pressure, trailer light operation, and trailer
wheel lug nuts every time you attach a trailer
to the vehicle.

Be 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 tipsIn 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 per-
formance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always 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.

When 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.

Always 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 parking
brake, and then move the selector lever into
the P (Park) position. If you move the selector
lever to the P (Park) position before blocking
the wheels and applying the parking brake,
transmission damage could occur.

When 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 overload-
ing and/or overheating.

If the engine coolant rises to an extremely
high temperature when the air conditioning
system is on, turn off the air conditioner.
Coolant heat can be additionally vented by
opening the windows, switching the fan con-
trol to high and setting the temperature con-
