engine INFINITI G35 2006 Workshop Manual

WARNINGO Do not leave children, impaired adults, or
pets alone in your vehicle. They could ac-
cidentally injure themselves or others
through inadvertent operation of the ve-
hicle. Also, on hot, sunny days, tempera-
tures in a closed vehicle could quickly be-
come high enough to cause severe or pos-
sibly fatal injuries to people or animals.
O Closely supervise children when they are
around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously in-
jured. Keep the car locked, with the rear
seatback and trunk lid securely latched
when not in use, and prevent children's
access to car keys.
EXHAUST GAS (Carbon monoxide)
WARNINGDo not breathe exhaust gases; they contain
colorless and odorless carbon monoxide. Carbon monoxide is dangerous. It can cause
unconsciousness or death.
O If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle in-
spected immediately.
O Do not run the engine in closed spaces
such as a garage.
O Do not park the vehicle with the engine
running for any extended length of time.
O Keep the trunk lid closed while driving,
otherwise exhaust gases could be drawn
into the passenger compartment. If you
must drive with the trunk lid open, follow
these precautions:
Ð Open all the windows.
Ð Set the air recirculation switch OFF
and the fan control at high to circu-
late the air.
O If electrical wiring or other cable connec-
tions must pass to a trailer through the
seal on the trunk lid or the body, follow
the manufacturer's recommendation to prevent carbon monoxide entry into
the vehicle.
O If a special body, camper, or other equip-
ment is added for recreational or other
usage, follow the manufacturer's recom-
mendation to prevent carbon monoxide
entry into the vehicle. (Some recre-
ational vehicle appliances such as
stoves, refrigerators, heaters, etc. may
also generate carbon monoxide.)
O The exhaust system and body should be
inspected by a qualified mechanic when-
ever:
Ð Your vehicle is raised while being ser-
viced.
Ð You suspect that exhaust fumes are
entering into the passenger compart-
ment.
Ð You notice a change in the sound of
the exhaust system.
Ð You have had an accident involving
damage to the exhaust system, un-
derbody, or rear of the vehicle.PRECAUTIONS WHEN STARTING AND

THREE WAY CATALYST The three way catalyst is an emission con-
trol device installed in the exhaust
system. Exhaust gas in the converter is
burned at high temperatures to help re-
duce pollutants.
WARNINGO The exhaust gas and the exhaust system
are very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
O Do not stop or park the vehicle over flam-
mable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
CAUTIONO Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re- duce the three-way catalyst's ability to
help reduce exhaust pollutants.
O Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if no-
ticeable loss of performance or other un-
usual operating conditions are detected.
Have the vehicle inspected promptly by
an INFINITI dealer.
O Avoid driving with an extremely low fuel
level. Running out of fuel could cause the
engine to misfire, damaging the
three-way catalyst.
O Do not race the engine while warming it
up.
O Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS) Each tire, including the spare (if provided),
should be checked monthly when cold and inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi-
nates a low tire pressure telltale when
one or more of your tires is significantly
under-inflated. Accordingly, when the low
tire pressure telltale illuminates, you
should stop and check your tires as soon
as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-
inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's
handling and stopping ability.
Please note that the TPMS is not a substi-
tute for proper tire maintenance, and it is
the driver's responsibility to maintain cor-
rect tire pressure, even if under-inflation
has not reached the level to trigger illumi-
nation of the TPMS low tire pressure tell-
tale.

INFINITI VEHICLE IMMOBILIZER
SYSTEM The INFINITI Vehicle Immobilizer System
will not allow the engine to start without
the use of the registered key. If the engine fails to start using a regis-
tered key (for example, when interference
is caused by another registered key, an
automated toll road device or automated
payment device on the key ring), restart
the engine using the following proce-
dures:
1. Leave the ignition switch in the ON po-
sition for approximately 5 seconds.
2. Turn the ignition switch to the OFF or
LOCK position and wait approximately
10 seconds.
3. Repeat steps 1 and 2.

AUTOMATIC TRANSMISSION
5-speed automatic transmission The automatic transmission in your ve-
hicle is electronically controlled by a
transmission control module to produce
maximum efficiency and smooth opera-
tion.
Shown on the following pages are the rec-
ommended operating procedures for this
transmission. Follow these procedures for
maximum vehicle performance and
driving enjoyment.
Starting the vehicle After starting the engine, fully depress the
foot brake pedal and push the selector le-
ver button before shifting the selector
lever to the R (Reverse), N (Neutral), D
(Drive) or Manual shift mode position. Be
sure the vehicle is fully stopped before at-
tempting to shift the selector lever.
This automatic transmission model is de-
signed so that the foot brake pedal must
be depressed before shifting from P (Park)
to any drive position while the ignition
switch is the ON position.
The selector lever cannot be moved out of
the P (Park) position and into any of the other gear positions if the ignition switch
is turned to the LOCK, OFF or ACC position
or if the key is removed from the switch.
1. Keep the foot brake pedal depressed
and push the selector lever button to
shift into a driving gear.
2. Release the parking brake and foot
brake, then gradually start the vehicle
in motion.
WARNING O Do not depress the accelerator pedal
while shifting from P (Park) or N (Neutral)
to R (Reverse), D (Drive) or manual shift
mode. Always depress the brake pedal
until shifting is completed. Failure to do
so could cause you to lose control and
have an accident.
O Cold engine idle speed is high, so use
caution when shifting into a forward or
reverse gear before the engine has
warmed up.
O On slippery roads, do not downshift.
This may cause a loss of control. O Never shift to P (Park) or R (Reverse)
while vehicle is moving forward. Never
shift to P (Park) or D (Drive) while vehicle
is moving rearward. Failure to do so
could cause you to lose control and have
an accident.
CAUTION When stopping the vehicle on an uphill
grade, do not hold the vehicle by depressing
the accelerator pedal. The foot brake should
be used for this purpose.DRIVING THE VEHICLE

: Push the button while depressing
the brake pedal,
: Push the button,
: Just move the selector lever.
Shifting After starting the engine, fully depress the
brake pedal and shift the selector lever
from the P (Park) to R (Reverse), N (Neu-
tral), D (Drive), or Manual shift mode posi-
tion.
Push the button to shift into the P (Park)
or R (Reverse) position. All other positions can be selected without pushing the
button.
WARNING Apply the parking brake if the selector lever
is in any position while the engine is not run-
ning. Failure to do so could cause the vehicle
to move unexpectedly or roll away and result
in serious personal injury or property
damage.
If the key is turned to the OFF or ACC po-
sition for any reason while the vehicle is
in the R (Reverse), N (Neutral), or any D
(Drive) position, the key cannot be turned
to the LOCK position and be removed
from the ignition switch. Move the se-
lector lever to the P (Park) position, then
the key can be turned to the LOCK posi-
tion.
P (Park):
Use this selector position when the vehicle
is parked or when starting the engine.
Make sure the vehicle is completely
stopped. The brake pedal must be de-
pressed and the selector lever button
pushed in to move the selector lever from the N (Neutral) position or any drive position
to the P (Park) position. Apply the parking
brake. When parking on a hill, first depress
the foot brake pedal, apply the parking
brake, then move the lever to the P (Park)
position.
CAUTION Use this position only when the vehicle is
completely stopped.
R (Reverse):
Use this position to back up. Always be
sure the vehicle is completely stopped be-
fore selecting the R (Reverse) position.
The brake pedal must be depressed and
the selector lever button pushed in to
move the selector lever from the P (Park), N
(Neutral) or any drive position to the R (Re-
verse) position.
N (Neutral):
Neither forward nor reverse gear is en-
gaged. The engine can be started in this
position. You may shift to the N (Neutral)
position and restart a stalled engine while
the vehicle is moving.SSD0413

D (Drive):
Use this position for all normal forward
driving.
Manual shift mode When the selector lever is shifted from
the D position to the manual shift gate
with the vehicle stopped or while driving,
the transmission enters the manual shift
mode. Shift range can be selected manu-
ally.
In the manual shift mode, the shift range
is displayed on the position indicator in
the meter.
Shift ranges up or down one by one as
follows: 1 M
!
à 2 M
!
à 3 M
!
à 4 M
!
à 5 M
5 M
(5th):
Use this position for all normal forward
driving.
4 M
(4th):
For driving up or down long slopes where
engine braking would be advantageous. 3 M
(3rd) and 2 M
(2nd):
Use for hill climbing or engine braking on
downhill grades.
1 M
(1st):
Use this position when climbing steep
hills slowly or driving slowly through
deep snow, sand or mud, or for maximum
engine braking on steep downhill grades.
O Remember not to drive at high speeds
for extended periods of time in lower
than 4 M
range. This reduces gas mile-
age.
O When shifting up, move the selector
lever to the + (up) side. (Shifts to
higher range.)
O When shifting down, move the se-
lector lever to the þ (down) side.
(Shifts to lower range.)
O Moving the selector lever rapidly to
the same side twice will shift the
ranges in succession.
O When canceling the manual shift
mode, return the selector lever to the
D position. The transmission returns
to the normal driving mode. O In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving perfor-
mance and reduces the chance of ve-
hicle damage or loss of control.
In the manual shift mode, the transmission
automatically shifts down to 1st gear be-
fore the vehicle comes to a stop. When ac-
celerating again, it is necessary to shift up
to the desired range.
Accelerator downshift
Ð In D position Ð For passing or hill climbing, fully depress
the accelerator pedal to the floor. This
shifts the transmission down into the
lower gear, depending on the vehicle
speed.
Fail-safe When the fail-safe operation occurs, the
automatic transmission will be locked in
the 4th gear.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition

quence according to the vehicle speed.
To back up, depress the shift lever and
then move it to the R (Reverse) position
after stopping the vehicle completely.
If it is difficult to move the shift lever into
the R (Reverse) or 1 position (Low gear),
shift to the N (Neutral) position, and then
release the clutch pedal once. Fully de-
press the clutch pedal again and shift
into the R or 1 position.
WARNING O Do not downshift abruptly on slippery
roads. This may cause a loss of control.
O Do not over-rev the engine when shifting
to a lower gear. This may cause a loss of
control or engine damage. CAUTION O Do not rest your foot on the clutch pedal
while driving. This may damage the
clutch.
O Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
