CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle. Fail-
ure to follow these recommendations may re-
sult in shortened engine life and reduced
engine performance.
c Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
c Do not accelerate at full throttle in any gear.
c Avoid quick starts.
c Avoid hard braking as much as possible. c
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
c Drive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
c Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
c Select a gear range suitable to road condi-
tions.
c Avoid unnecessary engine idling.
c Keep your engine tuned up.
c Follow the recommended periodic mainte-
nance schedule.
c Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
c Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
c Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
c When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag. c
Use the recommended viscosity engine oil.

WARNING
cFor AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
c Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
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
dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
Your vehicle is equipped with full-time All-
Wheel Drive (AWD).
Switching the driving mode is not necessary. The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started.If any malfunction occurs in the AWD system
while the engine is running, the warning light
will come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high powertrain oil temperature. The
driving mode may change to two-wheel drive. If
the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light turns
off after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning
light blink slowly (about once per two seconds).
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the same,
tire pressure is correct and tires are not worn.
CAUTION
c
If the warning light remains on after the
above operation, have your vehicle checked
by an INFINITI retailer as soon as possible.
c If the warning light comes on while driving
there may be a malfunction in the AWD sys-
tem. Reduce the vehicle speed and have your
vehicle checked by an INFINITI retailer as
soon as possible.

Steering wheel:Check for changes in the steer-
ing conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that all
warning lights and chimes are operating prop-
erly.
Windshield defroster: Check that the air comes
out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Windshield wiper and washer*: Check that the
wipers and washer operate properly and that
the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or un-
der severe condition require frequent checks of
the battery fluid level.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines on
the reservoir.
Engine coolant level*: Check the coolant level
when the engine is cold. Engine drive belts*:
Make sure that the drive
belts are not frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level surface and turning off the
engine. Wait more than 10 or 15 minutes for the
oil to drain back into the oil pan.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by an INFINITI retailer. (See
ªPRECAUTIONS WHEN STARTING AND DRIVINGº
in the ª5. Starting and drivingº section for
exhaust gas (carbon monoxide).)
Fluid leaks: Check under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from
the air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes are
evident, check for the cause and have it cor-
rected immediately.
Power steering fluid level* and lines: Check the
level when the fluid is cold, with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves, etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody:
The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, being careful
to clean those areas where mud and dirt may
accumulate. For additional information, see
ªCLEANING EXTERIORº in the ª7. Appearance
and careº section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.

When performing any inspection or mainte-
nance work on your vehicle, always take care to
prevent serious accidental injury to yourself or
damage to the vehicle. The following are gen-
eral precautions which should be closely ob-
served.
WARNING
cPark the vehicle on a level surface, apply the
parking brake securely and block the wheels
to prevent the vehicle from moving. Move
the selector lever to P (Park).
c Be sure the ignition switch is in the LOCK
position when performing any parts replace-
ment or repairs.
c If you must work with the engine running,
keep your hands, clothing, hair and tools
away from moving fans, belts and any other
moving parts.
c It is advisable to secure or remove any loose
clothing and remove any jewelry, such as
rings, watches, etc. before working on your
vehicle.
c Always wear eye protection whenever you
work on your vehicle. c
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.
c Never get under the vehicle while it is sup-
ported only by a jack. If it is necessary to
work under the vehicle, support it with
safety stands.
c Keep smoking materials, flame and sparks
away from fuel tank and the battery.
c Your vehicle is equipped with an automatic
engine cooling fan. It may come on at any
time without warning, even if the ignition
key is in the OFF position and the engine is
not running. To avoid injury, always discon-
nect the negative battery cable before work-
ing near the fan.
c The fuel filter or fuel lines should be serviced
by an INFINITI retailer because the fuel lines
are under high pressure even when the en-
gine is off.
CAUTION
cDo not work under the hood while the engine
is hot. Turn the engine off and wait until it
cools down. c
Avoid direct contact with used engine oil and
coolant. Improperly disposed engine oil, en-
gine coolant and/or other vehicle fluids can
damage the environment. Always conform to
local regulations for disposal of vehicle
fluid.
c Never connect or disconnect the battery or
any transistorized component while the ig-
nition switch is in the ON position.
c Never leave the engine or automatic trans-
mission related component harnesses dis-
connected while the ignition switch is in the
ON position.
This ª8. Maintenance and do-it-yourselfº sec-
tion gives instructions regarding only those
items which are relatively easy for an owner to
perform.
A genuine INFINITI Service Manual is also avail-
able. (See ªOWNER'S MANUAL/SERVICE
MANUAL ORDER INFORMATIONº in the ª9. Tech-
nical and consumer informationº section.)
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could affect
warranty coverage. If in doubt about any servic-
ing, we recommend that it be done by an INFINITI
retailer.
