ignition system INFINITI G35 2006 Repair Manual

PASSENGER COMPARTMENT
CAUTIONNever use a fuse of a higher or lower am-
perage 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 oper-
ate, check for an open fuse. 1. Be sure the ignition switch and the
headlight switch are in the OFF posi-
tion.
2. Open the fuse box lid
q 1
.
3. Remove the fuse with the fuse puller
q 2
.
4. If the fuse is open
q A
, replace it with a
new fuse
q B
. Spare fuses
q 3
are
stored in the fuse box.
5. If a new fuse also opens, have the
electrical system checked and re-
paired by an INFINITI dealer. SDI1962 SDI1754

performance problems and/or fuel system
damage.
O The fuel must be unleaded and have an
octane rating no lower than that recom-
mended for unleaded gasoline.
O If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 10% oxygenate.
(MTBE may, however, be added up to
15%.)
O 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 avail-
able to ensure that all methanol blends
are suitable for use in INFINITI vehicles.
If any driveability problems such as en-
gine stalling and hard hot starting are ex-
perienced after using oxygenate-blend fu-
els, immediately change to a non-
oxygenate fuel or a fuel with a low blend
of MTBE. Take care not to spill gasoline during refu-
eling. Gasoline containing oxygenates can
cause paint damage.
E-85 fuel E-85 fuel is a mixture of approximately
85% fuel ethanol and 15% unleaded gaso-
line. 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 abbre-
viation or the appropriate percentage for
that region.
Aftermarket fuel additives INFINITI does not recommend the use of
any aftermarket fuel additives (i.e. fuel in-
jector cleaner, octane booster, intake
valve deposit removers, etc.) which are
sold commercially. Many of these addi-
tives intended for gum, varnish or deposit
removal may contain active solvent or
similar ingredients that can be harmful to
the fuel system and engine.
Octane rating tips Using unleaded gasoline with an octane
rating lower than recommended can cause persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If
you detect a persistent heavy spark knock
even when using gasoline of the stated oc-
tane rating, or if you hear steady spark
knock while holding a steady speed on
level roads, have your dealer 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 consump-
tion or damage to the engine. If any of the
above symptoms are encountered, have
your vehicle checked at an INFINITI dealer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while ac-
celerating 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
engine load.

A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dyna-
mometers used by some states for emis-
sions testing), or similar equipment. Make
sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Us-
ing the wrong test equipment may result
in transmission damage or unexpected
vehicle movement which could result in
serious vehicle damage or personal in-
jury.
Due to legal requirements in some states/
areas, your vehicle may be required to be
in what is called the ªready conditionº for
an Inspection/Maintenance (I/M) test of
the emission control system.
The vehicle is set to the ªready conditionº
when it is driven through certain driving
patterns. Usually, the ªready conditionº
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is re-
paired or the battery is disconnected, the
vehicle may be reset to a not ªready con-
ditionº. Before taking the I/M test, check
the vehicle's inspection/maintenance test
readiness condition. Turn the ignition switch ON without starting the engine. If
the Malfunction Indicator Lamp (MIL)
comes on steady for 20 seconds and then
blinks for 10 seconds, the I/M test condi-
tion is ªnot readyº. If the MIL does not
blink after 20 seconds, the I/M test condi-
tion is ªreadyº. If the MIL indicates the
vehicle is in a ªnot readyº condition, drive
the vehicle through the following pattern
to set the vehicle to the ready condition.
If you cannot or do not want to perform
the driving pattern, an INFINITI dealer can
conduct it for you.
WARNING Always drive the vehicle in a safe and pru-
dent manner according to traffic conditions
and obey all traffic laws.
1. Start the engine. Allow the engine to
idle until the engine coolant tempera-
ture gauge needle points between the
C and H (normal operating tempera-
ture).
2. Accelerate the vehicle to 55 MPH (88
km/h), then quickly release the accel-
erator pedal completely and keep it re-
leased for at least 10 seconds. 3. Quickly depress the accelerator pedal
for a moment, then drive the vehicle at
a speed of 53 to 60 MPH (86 to 96
km/h) for at least 9 minutes.
4. Stop the vehicle. Leave the engine
running.
5. Accelerate the vehicle to 35 MPH (55
km/h) and maintain the speed for 20
seconds.
6. Repeat steps 4 and 5 at least 10 times.
7. Accelerate the vehicle to 55 MPH (88
km/h) and maintain the speed for at
least 3 minutes.
8. Stop the vehicle. Place the automatic
transmission selector lever in the ªPº
or ªNº position or the manual trans-
mission shift lever in the ªNº position.
9. Turn the engine off.
10. Repeat steps 1 through 8 at least one
more time.
If step 1 through 7 is interrupted, repeat
the preceding step. Any safe driving mode
is acceptable between steps. Do not stop
the engine until step 7 is completed.READINESS FOR INSPECTION/
