5-126Starting and driving
.Keep your engine tuned up.
.Follow the recommended scheduled
maintenance.
.Keep the tires inflated to the correct
pressure. Low tire pressure increases tire
wear and lowers fuel economy.
.Keep the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
.Use the recommended viscosity engine
oil. (See “Engine oil and oil filter recom-
mendation” (P.10-8).)If any malfunction occurs in the Intelligent
All-Wheel Drive (AWD) system while the
engine is running, warning messages appear
in the vehicle information display.

If the “AWD Error” warningappears, there
may be a malfunction in the Intelligent AWD
system. Reduce vehicle speed and have the
system checked as soon as possible. It is
recommended you visit an INFINITI retailer
for this service.
The “AWD High Temp.” (high temperature)
warning
may appear while trying to free a
INCREASING FUEL ECONOMYINTELLIGENT ALL-WHEEL
DRIVE (AWD) (if so equipped)

stuck vehicle due to increased oil tempera-
ture. The driving mode may change to Two-
Wheel Drive (2WD). If this warning is
displayed, stop the vehicle with the engine
idling, as soon as it is safe to do so. Then if
the warning turns off, you can continue
driving.
The “Tire Size Incorrect” warning
may
appear if there is a large difference between
the diameters of front and rear wheels. Pull
off the road in a safe area, with the engine
idling. Check that all tire sizes are the same,
that the tire pressure is correct and that the
tires are not excessively worn.
If any warning message continues to be
displayed, have your vehicle checked as soon
as possible. It is recommended you visit an
INFINITI retailer for this service.
WARNING
.For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result
in serious vehicle damage or personal
injury..Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
AWD before it is placed on a dynam-
ometer. Using the wrong test equip-
ment may result in drivetrain damage
or unexpected vehicle movement
which could result in serious vehicle
damage or personal injury.
CAUTION
.Do not operate the engine on a free
roller when any of the wheels are
raised.
.If the “AWD Error” warning appears
while driving there may be a mal-
function in the AWD system. Reduce
the vehicle speed and have your
vehicle checked as soon as possible.
It is recommended you visit an
INFINITI retailer for this service.
.If the “AWD Error” warning remains
on after the above operation, haveyour vehicle checked as soon as
possible. It is recommended you visit
an INFINITI retailer for this service.
.The power train may be damaged if
you continue driving with the “AWD
Error” warning on.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the
vehicle from moving. Move the shift
lever to P (Park).
.Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
.Never connect or disconnect the
battery or any transistorized compo-
nent while the ignition switch is in the
ON position.
.Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion switch is in the ON position.
.If you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other movingparts.
.It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
.Always wear eye protection when-
ever you work on your vehicle.
.If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
.Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
.Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
.Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always dis-
connect the negative battery cable
before working near the fan.
.Because the fuel lines are under high
pressure even when the engine is off,
it is recommended you visit an
INFINITI retailer for service of thefuel filter or fuel lines.
CAUTION
.Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
.Avoid direct contact with used en-
gine oil and coolant. Improperly dis-
posed engine oil, coolant, and/or
other vehicle fluids can damage the
environment. Always conform to lo-
cal regulations for disposal of vehicle
fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items which
are relatively easy for an owner to perform.
A genuine INFINITI Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-25).)
