restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
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 no belt is
frayed, worn, cracked or oily.
Engine oil level*: Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 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
“PRECAUTIONS WHEN STARTING AND DRIVING”
in the “5. Starting and driving” 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
“CLEANING EXTERIOR” in the “7. Appearance
and care” section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.

CAUTION
●Do not ground accessories directly to the
battery terminal. Doing so will bypass the
variable voltage control system and the ve-
hicle battery may not charge completely.
● Use electrical accessories with the engine
running to avoid discharging the vehicle
battery.
The variable voltage control system measures
the amount of electrical discharge from the
battery and controls voltage generated by the
generator.

change the oil before the first recommended
change interval. Oil and filter change intervals
depend upon how you use your vehicle. Opera-
tion under the following conditions may require
more frequent oil and filter changes.
●repeated short distance driving at cold out-
side temperatures,
● driving in dusty conditions,
● extensive idling,
● stop and go “rush hour” traffic,
Refer to the “INFINITI Service and Maintenance
Guide” for the maintenance schedule.
AIR CONDITIONING SYSTEM
REFRIGERANT AND LUBRICANT
RECOMMENDATIONS
The air conditioning system in your INFINITI ve-
hicle must be charged with the refrigerant HFC-
134a (R-134a) and the lubricant, NISSAN A/C sys-
tem oil Type S or the exact equivalents.
CAUTION
The use of any other refrigerant or lubricant will
cause severe damage to the air conditioning
system and will require the replacement of all
air conditioner system components. The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s ozone
layer. Although this refrigerant does not affect
the earth’s atmosphere, certain governmental
regulations require the recovery and recycling
of any refrigerant during automotive air condi-
tioning system service. Your INFINITI retailer
has the trained technicians and equipment
needed to recover and recycle your air condi-
tioning system refrigerant.
Contact an INFINITI retailer when servicing your
air conditioning system.

Additional information concerning motor
vehicle safety may be obtained from
Transport Canada’s Road Safety Infor-
mation Centre at 1-800-333-0371 or on-
line at www.tc.gc.ca/roadsafety (English
speakers) or
www.tc.gc.ca/securiteroutiere (French
speakers).
To notify INFINITI of any safety concerns
please contact our Consumer Informa-
tion Centre toll free at 1-800-361-4792.A vehicle equipped with Intelligent All-Wheel
Drive (AWD) should never be tested using a two
wheel dynamometer (such as the dynamom-
eters used by some states for emissions test-
ing), or similar equipment. Make sure you in-
form test facility personnel that your vehicle is
equipped with AWD before it is placed on a
dynamometer. Using the wrong test equipment
may result in transmission damage or unex-
pected vehicle movement which could result in
serious vehicle damage or personal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds, the I/Mtest condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
Contact an INFINITI retailer to set the “ready
condition” or to prepare the vehicle for testing.

This vehicle is equipped with an Event Data Re-
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa-
tions, such as an air bag deployment or hitting a
road obstacle, data that will assist in under-
standing how a vehicle’s systems performed.
The EDR is designed to record data related to
vehicle dynamics and safety systems for a short
period of time, typically 30 seconds or less. The
EDR in this vehicle is designed to record such
data as:
●How various systems in your vehicle were
operating;
● Whether or not the driver and passenger
safety belts were buckled/fastened;
● How far (if at all) the driver was depressing
the accelerator and/or brake pedal; and,
● How fast the vehicle was traveling.
● Sounds are not recorded.
These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur. NOTE: EDR data are recorded
by your vehicle only if a nontrivial crash situa-
tion occurs; no data are recorded by the EDR
under normal driving conditions and no personal
data (e.g. name, gender, age and crash location)
are recorded. However, other parties, such as
law enforcement, could combine the EDR data with the type of personally identifying data rou-
tinely acquired during a crash investigation.
To read data recorded by an EDR, special equip-
ment is required and access to the vehicle or the
EDR is needed. In addition to the vehicle manu-
facturer and INFINITI retailer, other parties, such
as law enforcement, that have the special equip-
ment, can read the information if they have ac-
cess to the vehicle or the EDR. EDR data will only
be accessed with the consent of the vehicle
owner or lessee or as otherwise required or per-
mitted by law.
A genuine INFINITI Service Manual is the best
source of service and repair information for your
vehicle. Filled with wiring diagrams, illustra-
tions and step-by-step diagnostic and adjust-
ment procedures, this manual is the same one
used by the factory trained technicians working
at an INFINITI retailer. Also available are genu-
ine INFINITI Owner’s Manuals, and genuine
INFINITI Service and Owner’s Manuals for older
INFINITI models.
