MEMORY STORAGE
Two positions for the driver’s seat, steering
column and outside mirrors can be stored
in the automatic drive positioner memory.
Follow these procedures to use the mem-
ory system.
1. Adjust the driver’s seat, steering col-umn and outside mirrors to the desired
positions by manually operating each
adjusting switch. For additional infor-
mation, see “Seats”(P.1-2),“Tilt/tele-
scopic steering” (P.3-24) and“Outside
mirrors” (P.3-27).
2. Push the SET switch and, within 5 seconds, push the memory switch (1
or 2) fully for at least 1 second.
The indicator light for the pushed
memory switch will stay on for approxi-
mately 5 seconds after pushing the
switch.
When the memory is stored in the
memory switch (1 or 2), a buzzer will
sound.
If memory is stored in the same
memory switch, the previous memory
will be deleted.
Confirming memory storage
.
Push the ignition switch to the ON
position and push the SET switch. If
the main memory has not been stored,
the indicator light will come on for
approximately 0.5 seconds. When the
memory has stored in position, the
indicator light will stay on for approxi-
mately 5 seconds.
. If the battery cable is disconnected, or if
the fuse opens, the memory will be
canceled. In this case, reset the desired
position using the previous procedure.

Selecting the memorized position
1. Move the shift lever to the P (Park)position.
2. Push the memory switch (1 or 2) fully for at least 1 second.
The driver’s seat, steering column and
outside mirrors will move to the mem-
orized position with the indicator light
flashing, and then the light will stay on
for approximately 5 seconds.
Linking log-in function to a stored
memory position
The log-in function can be linked to a
stored memory position with the following
procedure.
1. Place the ignition switch in the ONposition while carrying an Intelligent
Key that was registered to the vehicle
with the log-in function. For more
details, see “Log-in function” (P.3-14).
2. Adjust the position of the driver’s seat, steering column and outside mirrors
manually. See “Seats”(P.1-2),“Tilt/
telescopic steering” (P.3-24) and“Out-
side mirrors” (P.3-27).
3. Place the ignition switch in the OFF position. The next time you log in (selecting the user
on the display) after placing the ignition
switch in the ON position while carrying
the Intelligent Key, the system will auto-
matically adjust to the memorized driving
position.
SYSTEM OPERATION
The automatic drive positioner system will
not work or will stop operating under the
following conditions:
.
When the vehicle is moving.
. When the adjusting switch for the
driver’s seat and steering column is
turned on while the automatic drive
positioner is operating.
. When the memory switch 1 or 2 is
pushed for less than 1 second.
. When the seat, steering column and
outside mirrors have already been
moved to the memorized position.
. When no position is stored in the
memory switch.
. When the shift lever is moved from the
P (Park) position to any other position.
(However, it will not be canceled if the
switch is pushed while the seat and
steering column are returning to the
previous positions (entry/exit func- tion).)

THREE-WAY CATALYST
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)
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.
If the vehicle is being driven with one or
more flat tires, the low tire pressure
warning light will illuminate continuously
and a chime will sound for 10 seconds. The
flat tire warning will also appear in the
vehicle information display. The chime will
only sound at the first indication of a flat
tire, and the warning light will illuminate
continuously. When the flat tire warning is
activated, have the system reset and the
tire checked and replaced if necessary by
an INFINITI retailer. Even if the tire is
inflated to the specified COLD tire pres-
sure, the warning light will continue to

TPMS and cause the low tire pressure
warning light to illuminate. Some exam-
ples are:
.Facilities or electric devices using simi-
lar radio frequencies are near the
vehicle.
. If a transmitter set to similar frequen-
cies is being used in or near the
vehicle.
. If a computer (or similar equipment) or
a DC/AC converter is being used in or
near the vehicle.

TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire,
the TPMS with Tire Inflation Indicator
provides visual and audible signals out-
side the vehicle to help you inflate the tires
to the recommended COLD tire pressure.
Vehicle set-up:
1. Park the vehicle in a safe and level
place.
2. Apply the parking brake and place the shift lever in the P (Park) position.
3. Place the ignition switch in the ON position. Do not start the engine.
Operation:
1. Add air to the tire. 2. After a few seconds, the hazard indica-
tors will start flashing.
3. When the designated pressure is reached, the horn beeps once and the
hazard indicators stop flashing.
4. Perform the above steps for each tire.
. If the tire is over-inflated more than
approximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash 3
times. To correct the pressure, push the
core of the valve stem on the tire briefly
to release pressure. When the pressure
reaches the designated pressure, the
horn beeps once.
. If the hazard indicator does not flash
within approximately 15 seconds after
starting to inflate the tire, it indicates
that the Tire Inflation Indicator is not
operating.
. The TPMS will not activate the Tire
Inflation Indicator under the following
conditions:
— If there is interference from an
external device or transmitter
— The air pressure from the inflation
device such as those using a power
socket is not sufficient to inflate the
tire

INTELLIGENT ALL-WHEEL DRIVE
(AWD) DRIVING SAFETY PRECAU-
TIONS (AWD models)
WARNING
.Do not drive beyond the performance
capability of the tires, even with Intelli-
gent AWD engaged. Accelerating quickly,
sharp steering maneuvers or sudden
braking may cause loss of control.
. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
. This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to any D (Drive) or R (Reverse) position with
the engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result in
serious vehicle damage or personal
injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing), or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (The engine will stop when the
ignition switch is pushed 3 consecutive
times or the ignition switch is pushed and
held for more than 2 seconds.) If the engine
stops while the vehicle is being driven, this
could lead to a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the shift lever to
the P (Park) position.
