The three-way catalyst is an emission
control device installed in the exhaust
system. Exhaust gases in the three-way
catalyst are burned at high temperatures to
help reduce pollutants.
WARNING. The exhaust gas and the exhaust system
are very hot. Keep people, animals or
flammable materials away from the
exhaust system components.
. Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
CAUTION. Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst ’ s ability to help
reduce exhaust pollutants.
. Keep your engine tuned up. Malfunctions
in the ignition, fuel injection, or elec-
trical 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 noticeable loss of
performance or other unusual operating
conditions are detected. Have the vehicle
inspected promptly by an INFINITI retai-
ler.
. Avoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
. Do not race the engine while warming it
up.
. Do not push or tow your vehicle to start
the engine.
TIRE PRESSURE MONITORING SYS-
TEM (TPMS) GUID-01A54468-A798-4FEE-AB71-4E7737FDCB1C
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
label. (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 illuminates
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 overheat 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
substitute for proper tire maintenance,
and it is the driver ’ s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one

INTELLIGENT KEY BATTERY DIS-
CHARGE GUID-9671F916-0B52-40C4-A8B6-C2EBEE799C79
If the battery of the Intelligent Key is
almost discharged, the guide light
* B
of
the Intelligent Key port
* A
blinks and the
indicator appears on the dot matrix liquid
crystal display. (See “ Dot matrix liquid
crystal display ” (P.2-20).)
In this case, inserting the Intelligent Key
into the port

Use these positions for hill climbing or
engine braking on downhill grades. M
1 (1st): GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
Use this position when climbing steep hills
slowly or driving slowly through deep
snow, or for maximum engine braking on
steep downhill grades.
. Remember not to drive at high speeds
for extended periods of time in lower
than 7th gear. This reduces fuel econ-
omy.
. Moving the selector lever rapidly to the
same side twice will shift the ranges in
succession.
. 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
vehicle damage or loss of control.
When this situation occurs, the Auto-
matic Transmission (AT) position indi-
cator light (on the dot matrix liquid
crystal display) will blink and the
chime will sound.
. In the manual shift mode, the transmis-
sion automatically shifts down to 1st
gear before the vehicle comes to a stop. When accelerating again, it is
necessary to shift up to the desired
range.
Accelerator downshift — In D (Drive)
position — GUID-E91E596E-66F0-4B37-B592-BD241B7B4C14
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 GUID-852B8196-DDA1-4E5B-AA0C-3EDBD2A757EE
When the fail-safe operation occurs, note
that the transmission will be locked in any
of the forward gears according to the
condition.
If the vehicle is driven under extreme
conditions, such as excessive wheel spin-
ning 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, push
the ignition switch to the OFF position and
wait for 3 seconds. Then push the ignition
switch back to the ON position. The vehicle
should return to its normal operating
condition. If it does not return to its
normal operating condition, have an
INFINITI retailer check the transmission
and repair if necessary. SSD0598

Adaptive shift control (ASC) GUID-F11A26ED-2920-48C5-B33E-4D8F7EBFD667
The adaptive shift control system automa-
tically operates when the transmission is
in the "D" (drive) and "DS" (Drive Sport)
position and selects an appropriate gear
depending on the road conditions such as
uphill, downhill or curving roads.
Control on uphill and curving roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
A low gear is maintained that suits the
degree of the slope or curve to allow
smooth driving with a small number of
shifts.
Control on downhill roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
The adaptive shift control system shifts to
a low gear that suits the degree of the slope, and uses the engine braking to
reduce the number of times that the brake
must be used.
Control on winding roads: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel-
erator pedal is depressed.
NOTE:
. Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift
to a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by
the accelerator pedal when the vehicle
is in the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes
maintains a lower gear for a longer
period of time than when adaptive shift
control is not operating. Engine speed will be higher for a specific vehicle
speed while ASC system is operating
than when ASC is not operating.
MANUAL TRANSMISSION GUID-55540C91-1BB1-4931-BE6A-9E10E00B9B1A
WARNING . Do not downshift abruptly on slippery
roads. This may cause a loss of control.
. Do not over-rev the engine when shifting
to a lower gear. This may cause a loss of
control or engine damage.
CAUTION . Do not rest your foot on the clutch pedal
while driving. This may damage the
clutch.
. Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
. Stop your vehicle completely before
shifting into R (Reverse).
. When the vehicle is stopped for a period
of time, for example at a stop light, shift
to N (Neutral) and release the clutch
