The TSR system provides the driver with in-
formation about the most recently detected
speed limit. The system captures the road
sign information with the multi-sensing front
camera unit
O1located on the windshield in
front of the inside rearview mirror and dis-
plays the detected signs in the vehicle infor-
mation display. For vehicles equipped with a
navigation system, the speed limit displayed
is based on a combination of navigation sys-
tem data and live camera recognition. TSR
information is always displayed at the top of
the vehicle information display, and option-
ally in the main central area of the display
screen.
WARNING
The TSR system is only intended to be a
support device to help provide the driver
with information. It is not a replacement
for the driver’s attention to traffic condi-
tions or responsibility to drive safely. It
cannot prevent accidents due to careless-
ness. It is the driver’s responsibility to stay
alert and drive safely at all times.

5-32Starting and driving

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 flu-
ids can damage the environment. Always
conform 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.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

If you should notice any leaks or if fuel fumes
are evident, check for the cause and have it
corrected immediately.
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, oth-
erwise rust may form on the floor pan, frame,
fuel lines and around the exhaust system. At
the end of winter, the underbody should be
thoroughly flushed with plain water, being
careful to clean those areas where mud and
dirt may accumulate. For additional informa-
tion, see “Cleaning exterior” (P. 7-2).
Windshield-washer fluid*: Check that there
is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the sched-
uled maintenance items that should be regu-
larly checked or replaced. The maintenance
schedule indicates at which mileage/time in-
tervals each item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. For ad-
ditional information, see “General mainte-
nance” (P. 9-2).
Items marked with
“*”are recommended by
INFINITI for reliable vehicle operation. You
are not required to perform maintenance on
these items in order to maintain the warran-
ties which come with your INFINITI. Other
maintenance items and intervals are required.
When applicable, additional information can
be found in the “Do-it-yourself” section of
this manual.NOTE:
INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been vali-
dated by INFINITI.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, see “Recommended
fluids/lubricants and capacities” (P. 10-2).
EMISSION CONTROL SYSTEM
MAINTENANCE:
Engine Drive belt*: Check engine drive belt
for wear, fraying or cracking and for proper
tension. Replace any damaged drive belt.
Engine air filter: Replace at specified inter-
vals. When driving for prolonged periods in
dusty conditions, check/replace the filter
more frequently.
Engine coolant*: Replace coolant at the
specified interval. When adding or replacing
coolant, be sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue) or

equivalent with the proper mixture. (For ad-
ditional information on the proper mixture for
your area, see “Engine cooling system”
(P. 8-4).)
NOTE: Mixing any other type of coolant or
the use of non-distilled water may reduce
the recommended service interval of the
coolant.
Engine oil and oil filter:Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity, see
“Recommended fluids/lubricants and capaci-
ties” (P. 10-2).

necessary.
Fuel lines/connections*: Check the fuel
hoses, piping and connections for leaks,
looseness, or deterioration. Tighten connec-
tions or replace parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing, cracks,
deterioration, and signs of leaking. Replace
any deteriorated or damaged parts
immediately.
Brake pads and rotors: Check for wear, de-
terioration and fluid leaks. Replace any dete-
riorated or damaged parts immediately.
Exhaust system: Visually inspect the exhaust
pipes, muffler and hangers for leaks, cracks,
deterioration, and damage. Tighten connec-
tions or replace parts as necessary.

RECOMMENDED FLUIDS/
LUBRICANTS AND CAPACITIES
10-2Technical and consumer information

Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that you visit an INFINITI
retailer.
However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is not a cause for
concern, because you get the greatest fuel
benefit when there is light spark knock for a
short time under heavy engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATIONS
Selecting the correct oil
It is essential to choose the correct grade, qual-
ity and viscosity engine oil to ensure satisfac-
tory engine life and performance. For addi-
tional information, see "Recommended fluids/
lubricants and capacities" (P. 10-2). INFINITI
recommends the use of an energy conserving
oil in order to improve fuel economy.
Select only engine oils that meet the Ameri-
can Petroleum Institute (API) certification or
International Lubricant Standardization andApproval Committee (ILSAC) certification
and SAE viscosity standard. These oils have
the API certification mark on the front of the
container. Oils which do not have the speci-
fied quality label should not be used as they
could cause engine damage.
Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
