SIC4474
TOW mode should be used when pulling a
heavy trailer or hauling a heavy load. Driving
the vehicle in TOW mode with no trailer/
load or light trailer/light load will not cause
any damage. However, fuel economy may be
reduced, and the transmission/engine driv-
ing characteristics may feel unusual.
Push the TOW mode switch to activate
TOW mode. The indicator light in the vehicle
information display illuminates when TOW
mode is selected. Push the TOW mode
switch again to turn TOW mode off.
TOW mode is automatically canceled when
the ignition switch is placed in the OFF
position.
SIC4455
The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most
driving conditions.
If the vehicle is stuck in mud or snow, the
VDC system reduces the engine output to
reduce wheel spin. The engine speed will be
reduced even if the accelerator is depressed
to the floor. If maximum engine power is
needed to free a stuck vehicle, turn the VDC
system off.
To turn off the VDC system, push the VDC
OFF switch. The
indicator will illumi-
nate.
Push the VDC OFF switch again or restart
the engine to turn on the system. (See
“Vehicle Dynamic Control (VDC) system” (P.5-124).)

WARNING
.Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
. The Intelligent Key transmits radio
waves when the buttons are pushed.
The FAA advises that the radio
waves may affect aircraft navigation
and communication systems. Do not
operate the Intelligent Key while on
an airplane. Make sure the buttons
are not operated unintentionally
when the unit is stored during a
flight.
The Intelligent Key system can operate all
the door locks using the remote controller
function or pushing the request switch on
the vehicle without taking the key out from a
pocket or purse. The operating environment
and/or conditions may affect the Intelligent
Key system operation.
Be sure to read the following before using
the Intelligent Key system.
CAUTION
. Be sure to carry the Intelligent Key
with you when operating the vehicle.
. Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
interfere with the operation of the Intelligent
Key system under the following operating
conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
. When in possession of wireless equip-
ment, such as a cellular telephone,
transceiver, and CB radio.
. When the Intelligent Key is in contact
with or covered by metallic materials.
. When any type of radio wave remote
control is used nearby.
. When the Intelligent Key is placed near
an electric appliance such as a personal
computer. .
When the vehicle is parked near a parking
meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions, the
battery’s life is approximately 2 years. If the
battery is discharged, replace it with a new
one.
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replace-
ment” (P.8-21).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, contact an

telligent Key system” (P.3-7) for additional
information.
REMOTE ENGINE START OPER-
ATING RANGE
The remote engine start function can only be
used when the Intelligent Key is within the
specified operating range from the vehicle.
When the Intelligent Key battery is dis-
charged or other strong radio wave sources
are present near the operating location, the
Intelligent Key operating range becomes
narrower, and the Intelligent Key may not
function properly.
The remote engine start operating range is
approximately 197 ft (60 m) from the
vehicle.
REMOTE STARTING THE ENGINE
To use the remote engine start function to
start the engine, perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Push the “LOCK”
button to lock all
doors.
3. Within 5 seconds push and hold the remote engine start
button until
the turn signal lights flash and the tail lights illuminate. If the vehicle is not
within view, push and hold the remote
engine start
button for at least 2
seconds.
The following events will occur when the
engine starts:
. The front parking lights will turn on and
remain on as long as the engine is
running.
. The doors will be locked and the air
conditioner system may turn on.
. The engine will continue to run for about
10 minutes. Repeat the steps to extend
the time for an additional 10 minutes.
See “Extending engine run time” (P.3-
19).
Depress and hold the brake pedal, then place
the ignition switch in the ON position before

listed in “Remote starting the engine” (P.3-
19). Run time will be calculated as follows:
. The first 10 minute run time will start
when the remote engine start function is
performed.
. The second 10 minutes will start imme-
diately when the remote engine start function is performed. For example, if
the engine has been running for 5
minutes, and 10 minutes are added, the
engine will run for a total of 15 minutes.
. Extending engine run time will count
towards the two remote engine start
limit.
A maximum of two remote engine starts, or
a single start with an extension, are allowed
between ignition cycles.
The ignition switch must be cycled to the ON

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. 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
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly. It is recommended
you visit an INFINITI retailer for this
service.
. 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
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
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 Mon-
itoring 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 sub-
stitute 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
minute and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Additional information
.
Since the spare tire is not equipped with
the TPMS, the TPMS does not monitor
the tire pressure of the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16
MPH (25 km/h). Also, this system may

it rolls forward, backward or side-
ways, you could be injured.
. Whenever you drive off-road
through sand, mud or water as deep
as the wheel hub, more frequent
maintenance may be required. See
the maintenance schedules shown in
the "9. Maintenance and schedules"
section.
. Spinning the rear wheels on slippery
surfaces may cause the 4WD warn-
ing light to flash. The 4WD system
may also automatically switch from
the 4WD mode to the 2WD mode.
This could reduce traction. Be espe-
cially careful when towing a trailer
(4WD models).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.
