CVT (AT) Malfunction Service now
This warning appears when there is a prob-
lem with the CVT system. If this warning
comes on, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
CVT (AT) hot Power reduced
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with heavy
loads), engine power and, under some condi-
tions, vehicle speed will be decreased auto-
matically to reduce the chance of transmis-
sion damage. Vehicle speed can be controlled
with the accelerator pedal, but the engine
and vehicle speed may be reduced.
WARNING
When the high fluid temperature protec-
tion mode operation occurs, vehicle speed
may be gradually reduced. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
necessary, pull to the side of the road at a
safe place and allow the transmission to
return to normal operation; or have it re-
paired if necessary.
Engine hot Power reduced
This engine has a high fluid temperature pro-
tection mode. If the fluid temperature be-
comes too high (for example, climbing steep
grades in high temperatures with heavy
loads), engine power and, under some condi-
tions, vehicle speed will be decreased auto-
matically to reduce the chance of engine
damage. Vehicle speed can be controlled
with the accelerator pedal, but the engine
and vehicle speed may be reduced.

–– If the surface temperature of thesteering-wheel is above the temperature
within which the system is designed to
operate, the system will not heat the
steering-wheel. This is not a malfunction. The air conditioner system in your INFINITI
vehicle is charged with a refrigerant designed
with the environment in mind.
This refrigerant does not harm the earth's
ozone layer.
Special charging equipment and lubricant is
required when servicing your INFINITI air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to your
air conditioner system. For additional infor-
mation, see “Air conditioner system refriger-
ant and oil recommendations” (P. 10-7).
It is recommended that you visit an INFINITI
retailer for servicing your “environmentally
friendly” air conditioning system.
WARNING
The air conditioner system contains refrig-
erant under high pressure. To avoid per-
sonal injury, any air conditioner service
should be done only by an experienced
technician with proper equipment. The vehicle is equipped with a shark fin an-
tenna and an antenna pattern is printed in-
side the rear window.
CAUTION
• Do not place metalized film near the rear
window glass or attach any metal parts
to it. This may cause poor reception or

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:
1. Leave the ignition switch in the ON posi-tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately 5
seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the interfer-
ence) separate from the registered key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. • Make sure the area around the vehicle is
clear.
• Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
• Check that all windows and lights are clean.
• Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
• Check that all doors are closed.
• Position seat and adjust head restraints/headrests.
• Adjust inside and outside mirrors.
• Fasten seat belts and ask all passengers to do likewise.
• Check the operation of warning lights when the ignition switch is placed in the ON
position. For additional information, see
“Warning lights, indicator lights and audible
reminders” (P. 2-9) 1. Apply the parking brake.
2. Press the Park button to place the vehicle

• Wax your vehicle only after a thoroughwashing. Follow the instructions supplied
with the wax.
• Do not use a wax containing any abrasives, cutting compounds or cleaners that may
damage the vehicle finish.
Machine compounding or aggressive polish-
ing on a base coat/clear coat paint finish may
dull the finish or leave swirl marks.
REMOVING SPOTS
Remove tar and oil spots, industrial dust, in-
sects, and tree sap as quickly as possible from
the surface of the paint to avoid lasting dam-
age or staining. Special cleaning products are
available at an INFINITI retailer or any auto-
motive accessory store. It is recommended
that you visit an INFINITI retailer for these
products.
UNDERBODY
In areas where road salt is used in winter, it is
necessary to clean the underbody regularly in
order to prevent dirt and salt from building up
and causing the acceleration of corrosion on
the underbody and suspension. Before the
winter period and again in the spring, the
underseal must be checked and, if necessary,
re-treated.
GLASS
Use glass cleaner to remove smoke and dust
film from the glass surfaces. It is normal for
glass to become coated with a film after the
vehicle is parked in the hot sun. Glass cleaner
and a soft cloth will easily remove this film.
CAUTION
When cleaning the inside of the windows,
do not use sharp-edged tools, abrasive
cleaners or chlorine-based disinfectant
cleaners. They could damage the electrical
conductors, radio antenna elements or rear
window defroster elements.
ALUMINUM ALLOY WHEELS
Wash the wheels regularly with a sponge
dampened in a mild soap solution, especially
during winter months in areas where road
salt is used. If not removed, road salt can
discolor the wheels.
CAUTION
Follow the directions below to avoid stain-
ing or discoloring the wheels:
• Do not use a cleaner that uses strong acid
or alkali contents to clean the wheels.
• Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as am-
bient temperature.
• Rinse the wheel to completely remove
the cleaner within 15 minutes after the
cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.
CAUTION
Follow the directions below to avoid stain-
ing or discoloring the chrome parts:
• Do not use a cleaner that uses strong acid
or alkali contents to clean the chrome
parts.
Appearance and care7-3

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self 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 mov-
ing. Push the park button to engage the
P (Park) position.
• Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
• If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
• It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before work-
ing on your vehicle.
• Always wear eye protection whenever
you work on your vehicle.
• Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the ignition switch is in the OFF position and
the engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
• 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 the fuel tank and battery.
• Because the fuel lines on gasoline engine
models are under high pressure even
when the engine is off, it is recommended
that you visit an INFINITI retailer for ser-
vice of the fuel 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 contact with used engine oil and
coolant. Improperly disposed engine oil,
engine coolant and/or other vehicle fluids
can damage the environment. Always con-
form to local regulations for disposal of
vehicle fluid.
• Never leave the engine or Continuously
Variable Transmission (CVT) related
component harnesses disconnected
while the ignition switch is in the ON
position.
• Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
NOTE:
If the battery is completely drained the
transmission will not manually shift to other
positions.
This “Do-it-yourself” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine INFINITI service manual is also
available. For additional information, see
“Owner’s Manual/Service Manual order in-
formation” (P. 10-26).
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect warranty coverage. If in doubt about any
servicing, it is recommended that you have it
done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface andapply the parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than 10
minutes for the oil to drain back into the
oil pan.
4. Remove the dipstick and wipe it clean. Reinsert it all the way. 5. Remove the dipstick again and check the
oil level. It should be between the H (High)
and L (Low) marksOB. This is the normal
operating oil level range. If the oil level is
below the L (Low) mark
OA, remove the oil
filler cap and pour recommended oil
through the opening. Do not fill oil level
above H (High) mark
OC.
6. Recheck the oil level with the dipstick.
It is normal to add some oil between oil main-
tenance intervals or during the break-in pe-
riod, depending on the severity of operating
conditions.
CAUTION
Oil level should be checked regularly. Oper-
ating the engine with an insufficient
amount of oil can damage the engine, and
such damage is not covered by warranty.
