will decrease gradually with each de-
pression as the hydraulic pressure
decreases.
If the brakes do not operate properly, have
the brakes checked by an INFINITI retailer.

CAUTION
Never use a fuse of a higher or lower
amperage rating than that specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not
operate, check for an open fuse.
1. Be sure the ignition switch is pushed to the OFF or LOCK position and the
headlight switch is turned to OFF.
2. Open the engine hood and remove the cover on the battery.
3. Remove the fuse/fusible link holder cover
*1,*2or*3.
4. Remove the fuse with the fuse puller.

FUSES

fuel is not covered by the INFINITI new
vehicle limited warranty.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It
should also contain a suitable amount
of appropriate cosolvents and corro-
sion inhibitors. If not properly formu-
lated with appropriate cosolvents and
corrosion inhibitors, such methanol
blends may cause fuel system damage
and/or vehicle performance problems.
At this time, sufficient data is not
available to ensure that all methanol
blends are suitable for use in INFINITI
vehicles.
If any undesirable driveability problems
such as engine stalling or hard hot starting
are experienced after using oxygenate-
blend fuels, immediately change to a
non-oxygenate fuel or a fuel with a low
blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.
E-15 fuel
E-15 fuel is a mixture of approximately
15% fuel ethanol and 85% unleaded gasoline. E-15 can only be used in vehicles
designed to run on E-15 fuel. Do not use E-
15 in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified with small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
E-85 fuel
E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded
gasoline. E-85 can only be used in a
Flexible Fuel Vehicle (FFV). Do not use E-
85 fuel in your vehicle. U.S. government
regulations require fuel ethanol dispensing
pumps to be identified by a small, square,
orange and black label with the common
abbreviation or the appropriate percentage
for that region.
Aftermarket fuel additives
INFINITI does not recommend the use of
any aftermarket fuel additives (Example:
fuel injector cleaner, octane booster, intake
valve deposit removers, etc.) which are
sold commercially. Many of these additives
intended for gum, varnish or deposit
removal may contain active solvent or
similar ingredients that can be harmful tothe fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock.
(Spark knock is a metallic rapping noise.)
If severe, this can lead to engine damage.
If you detect a persistent 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, 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 will result in
knocking, after-run or overheating. This in
turn may cause excessive fuel consumption
or damage to the engine. If any of the
above symptoms are encountered, have
your vehicle checked at an INFINITI retailer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy

emergency”section.
. Trailer towing requires more fuel than
normal circumstances.
. Avoid towing a trailer for your vehicle’s
first 500 miles (800 km).
. Have your vehicle serviced more often
than at intervals specified in the
recommended maintenance schedule
in the INFINITI Service and Maintenance
Guide.
. When making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.
. Crosswinds and rough roads will ad-
versely affect vehicle/trailer handling,
possibly causing vehicle sway. When
being passed by larger vehicles, be
prepared for possible changes in cross-
winds that could affect vehicle hand-
ling.
Do the following if the trailer begins to
sway:
1. Take your foot off the accelerator pedal to allow the vehicle to coast and steer
as straight ahead as the road condi-
tions allow. This combination will help
stabilize the vehicle..Do not correct trailer sway by steer-ing or applying the brakes.
2. When the trailer sway stops, gently apply the brakes and pull to the side of
the road in a safe area.
3. Try to rearrange the trailer load so it is balanced as described earlier in this
section.
. Be careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than nor-
mal passing. Remember the length of
the trailer must also pass the other
vehicle before you can safely change
lanes.
. Use the Tow mode or downshift the
transmission to a lower gear for engine
braking when driving down steep or
long hills. This will help slow the
vehicle without applying the brakes.
. Avoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in
reduced braking efficiency.
. Increase your following distance to
allow for greater stopping distances
while towing a trailer. Anticipate stops
and brake gradually. .
INFINITI recommends that the cruise
control not be used while towing a
trailer.
. While towing a trailer, do not use the
following systems (if so equipped):
— the Lane Departure Prevention (LDP)
system
— the Blind Spot Warning (BSW) sys-
tem
— the Blind Spot Intervention system
— the Back-up Collision Intervention
(BCI) system (if so equipped)
— the Intelligent Cruise Control (ICC)
system
— the Distance Control Assist (DCA)
system
— the Intelligent Brake Assist (IBA)
system
. Some states or provinces have specific
regulations and speed limits for vehi-
cles that are towing trailers. Obey the
local speed limits.
. Check your hitch, trailer wiring harness
connections, and trailer wheel lug nuts
after 50 miles (80 km) of travel and at
every break.
. When launching a boat, do not allow
the water level to go over the exhaust

the vehicle may be reset to a“not ready
condition” . Before taking the I/M test,
check the vehicle’ s inspection/mainte-
nance test readiness condition. 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”.
Contact an INFINITI retailer to set “ready
condition” or to prepare 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 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 passen-
ger 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
understanding of the circumstances in
which crashes and injuries occur.
NOTE: EDR data are recorded by your
vehicle only if a nontrivial crash situation
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 routinely
acquired during a crash investigation.
To read data recorded by an EDR, special
equipment is required and access to the
vehicle or the EDR is needed. In addition to
the vehicle manufacturer and INFINITI
retailer, other parties, such as law enforce-
ment, that have the special equipment, can
read the information if they have access 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
permitted by law.
