6. If a new fuse also opens, have the electri- cal system checked and repaired. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
Fusible links
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace with only Genuine NISSAN
parts.

WARNING
Never use a fuse of higher or lower amper-
age rating than that specified on the fuse
box cover. This could damage the electrical
system or electronic control units or cause
a fire.
If any electrical equipment does not operate,
check for an open fuse.
NOTE:
The fuse box is located on the driver's side of
the instrument panel. 1. Be sure the ignition switch and the head-
light switch are OFF.

Octane rating tips
Using unleaded gasoline with an octane rat-
ing lower than recommended can cause per-
sistent, heavy “spark knock.” (“Spark knock”
is a metallic rapping noise.) If severe, this can
lead to engine damage. If you detect a per-
sistent heavy spark knock even when using
gasoline of the stated octane rating, or if you
hear steady spark knock while holding a
steady speed on level roads, it is recom-
mended that you have an INFINITI retailer
correct the condition. Failure to correct the
condition is misuse of the vehicle, for which
INFINITI is not responsible.
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.

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.

A weight-distributing hitch system (Class IV)
is recommended if you plan to tow trailers
with a maximum weight over 5,000 lbs.
(2,268 kg). Check with the trailer and towing
equipment manufacturers to determine if
they recommend the use of a weight-
distributing hitch system.
NOTE:
A weight-distributing hitch system may af-
fect the operation of trailer surge brakes. If
you are considering use of a weight-
distributing hitch system with a surge
brake-equipped trailer, check with the surge
brake, hitch or trailer manufacturer to de-
termine if and how this can be done.
Follow the instructions provided by the
manufacturer for installing and using the
weight-distributing hitch system.
General set-up instructions are as follows:
1. Park unloaded vehicle on a level surface.With the ignition switch in the ON position
and the doors closed, allow the vehicle to
stand for several minutes so that it can
level.
2. Measure the height of a reference point on the front and rear bumpers at the cen-
ter of the vehicle. 3. Attach the trailer to the vehicle and adjust
the hitch equalizers so that the front bum-
per height is within0-.5inches (0 – 13
mm) of the reference height measured in
step 2. The rear bumper should be no
higher than the reference height mea-
sured in step 2.
WARNING
Properly adjust the weight distributing
hitch so the rear of the bumper is no higher
than the measured reference height when
the trailer is attached. If the rear bumper is
higher than the measured reference height
when loaded, the vehicle may handle un-
predictably which could cause a loss of ve-
hicle control and cause serious personal in-
jury or property damage.
Sway control device
Sudden maneuvers, wind gusts, and buffet-
ing caused by other vehicles can affect trailer
handling. Sway control devices may be used
to help control these affects. If you choose to
use one, contact a reputable trailer hitch sup-
plier to make sure the sway control device will
work with the vehicle, hitch, trailer and the
trailer's brake system. Follow the instructions
provided by the manufacturer for installing
and using the sway control device.
Class I hitch
Class I trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 2,000 lbs.
(907 kg).
Class II hitch
Class II trailer hitch equipment (receiver, ball
mount and hitch ball) can be used to tow
trailers of a maximum weight of 3,500 lbs.
(1,587 kg).
Tire pressures
• When towing a trailer, inflate the vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information label.
• Trailer tire condition, size, load rating and proper inflation pressure should
be in accordance with the trailer and
tire manufacturer's specifications.
Safety chains
Always use suitable safety chains between
your vehicle and the trailer. The safety chains
should be crossed and should be attached to
the hitch, not to the vehicle bumper or axle.
Technical and consumer information10-25

If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a “not ready” condition. Be-
fore taking the I/M test, check the vehicle's
inspection/maintenance test readiness con-
dition. 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/M test condition is “not
ready”. If the MIL does not blink after 20
seconds, the I/M test condition is “ready”. It is
recommended that you visit an INFINITI re-
tailer to set the “ready condition” or to pre-
pare the vehicle for testing.This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an EDR
is to record, in certain crash or near crash-like
situations, such as an air bag deployment or
hitting a road obstacle, data that will assist in
understanding how a vehicle's systems per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems 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 non-
trivial crash situation occurs; no data are re-
corded by the EDR under normal driving con-
ditions and no personal data (e.g., name,
gender, age, and crash location) are recorded.
However, other parties, such as law enforce-
ment, could combine the EDR data with the
type of personally identifying data routinely
acquired during a crash investigation. To read data recorded by an EDR, special
equipment is required, and access to the ve-
hicle or the EDR is needed. In addition to the
vehicle manufacturer and INFINITI retailer,
other parties, such as law enforcement, that
have the special equipment, can read the in-
formation if they have access to the vehicle or
the EDR.
EDR data will only be accessed with the con-
sent of the vehicle owner or lessee or as
otherwise required or permitted by law.
ADDITIONAL DATA RECORDING
(on vehicles equipped with optional
ProPILOT Assist)
If your vehicle is equipped with the optional
ProPILOT Assist, it will also be equipped with
a supplemental vehicle data recording
function.
The data recording function is designed to
record such data as:
• Driver operational status of accelerator,
brakes, steering, etc.
• Detection status of a vehicle ahead and lane markers
• Vehicle information including distance to vehicle ahead and lateral position
