ECU NISSAN MURANO 2007 1.G Service Manual

— Do not place the Intelligent Key near
an electric appliance such as a tele-
vision set or personal computer.
— Do not place the Intelligent Key in a
storage area (for example, a door
pocket or glove box). It could be dam-
aged or activated unexpectedly.

Do not allow the Intelligent Key to
come into contact with water or salt
water, and be careful not to let the
key be washed in a washing machine.
This could affect the system function.

If an Intelligent Key or the mechani-
cal key is lost or stolen, NISSAN
recommends erasing the ID code of
that Intelligent Key. This will prevent
the Intelligent Key from unauthorized
use to unlock the vehicle. For infor-
mation regarding the erasing proce-
dure, please contact a NISSAN
dealer.

WARNING

Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.

Properly secure all cargo to help pre-
vent it from sliding or shifting. Do not
place cargo higher than the seat-
backs. In a sudden stop or collision,
unsecured cargo could cause per-
sonal injury.EXHAUST GAS (Carbon monoxide)
WARNING
Do not breathe exhaust gases; they con-tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous.
It can cause unconsciousness or death.

If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.

Do not run the engine in closed
spaces such as a garage.

Do not park the vehicle with the en-
gine running for any extended length
of time.

Keep the lift gate closed while driv-
ing, otherwise exhaust gases could
be drawn into the passenger com-
partment. If you must drive with the
lift gate open, follow these precau-
tions:
1. Open all the windows.
2. Set the air recirculation switch
OFF and the fan control at 4 (high)
to circulate the air.

If electrical wiring or other cable con-nections must pass to a trailer
through the seal on the lift gate or
the body, follow the manufacturer’s
recommendation to prevent carbon
monoxide entry into the vehicle.

If a special body, camper or other
equipment is added for recreational
or other usage, follow the manufac-
turer’s recommendation to prevent
carbon monoxide entry into the ve-
hicle. (Some recreational vehicle ap-
pliances such as stoves, refrigera-
tors, heaters, etc. may also generate
carbon monoxide.)

The exhaust system and body should
be inspected by a qualified mechanic
whenever:
a. The vehicle is raised for service.
b. You suspect that exhaust fumes
are entering into the passenger
compartment.
c. You notice a change in the sound
of the exhaust system.PRECAUTIONS WHEN STARTING
AND DRIVING5-2
Starting and driving

straight down the slopes. Off-road
vehicles can tip over sideways much
more easily than they can forward or
backward.

Many hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you may
not be able to control your speed. If
you drive across them, you may roll
over.

Do not shift ranges while driving on
downhill grades as this could cause
loss of control of the vehicle.

Be sure to use the engine brake. The
foot brake performance may be re-
duced, resulting in a possible acci-
dent.

Stay alert when driving to the top of a
hill. At the top there could be a drop-
off or other hazard that could cause
an accident.

If your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Yourvehicle could tip or roll over. Always
back straight down in R (Reverse)
range. Never back down in N (Neu-
tral), using only the brake, as this
could cause loss of control.

Heavy braking going down a hill
could cause your brakes to overheat
and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low range to control your
speed.

Unsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.

To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as
possible. Do not equip the vehicle
with tires larger than specified in this
manual. This could cause your ve-hicle to roll over.

Do not grip the inside or spokes of
the steering wheel when driving off-
road. The steering wheel could move
suddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim.

Before operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.

Always drive with the floor mats in
place as the floor may become hot.

Lower your speed when encountering
strong crosswinds. With a higher
center of gravity, your NISSAN is
more affected by strong side winds.
Slower speeds ensure better vehicle
control.

Do not drive beyond the performance
capability of the tires, even with AWD
engaged.
Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
