cause a malfunction of the tire pres-
sure sensors.
CAUTION
.The TPMS may not function properly
when the wheels are equipped with
tire chains or the wheels are buried in
snow.
. Do not place metalized film or any
metal parts (antenna, etc.) on the
windows. This may cause poor recep-
tion of the signals from the tire
pressure sensors, and the TPMS will
not function properly.
Some devices and transmitters may tem-
porarily interfere with the operation of the
TPMS and cause the low tire pressure
warning light to illuminate. Some examples
are:
. Facilities or electric devices using similar
radio frequencies are near the vehicle.
. If a transmitter set to similar frequencies
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.
Low tire pressure warning light may illumi- nate in the following cases.
.
If the vehicle is equipped with a wheel
and tire without TPMS.
. If the TPMS has been replaced and the ID
has not been registered.
. If the wheel is not originally specified by
INFINITI.
FCC Notice:
For USA:
This device complies with Part 15 of the
FCC Rules. Operation is subject to the
following two conditions: (1) This device
may not cause harmful interference, and (2)
this device must accept any interference
received, including interference that may
cause undesired operation.
Note: Changes or modifications not ex-
pressly approved by the party responsible
for compliance could void the user’s author-
ity to operate the equipment.
For Canada:
This device complies with Industry Canada
licence-exempt RSS standard(s). Operation
is subject to the following two conditions:
(1) this device may not cause interference,
and (2) this device must accept any inter-
ference, including interference that may
cause undesired operation of the device.
TPMS with Tire Inflation Indicator
When adding air to an under-inflated tire,
the TPMS with Tire Inflation Indicator
provides visual and audible signals outside
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.
Starting and driving5-7

5-8Starting and driving
.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 ex- ternal device or transmitter
— The air pressure from the inflation device such as those using a power
socket is not sufficient to inflate the
tire
— If an electrical equipment is being used in or near the vehicle
— There is a malfunction in the TPMS system
— There is a malfunction in the horn or hazard indicators
. If the Tire Inflation Indicator does not
operate due to TPMS interference, move
the vehicle about 3 ft (1m) backward or
forward and try again.
If the Tire Inflation Indicator is not working,
use a tire pressure gauge.AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe
and prudent manner may result in loss of
control or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden
steering maneuvers, because these driving
practices could cause you to lose control of
your vehicle. As with any vehicle, a loss of
control could result in a collision with other
vehicles or objects, or cause the vehicle to
rollover, particularly if the loss of control
causes the vehicle to slide sideways. Be
attentive at all times, and avoid driving when
tired. Never drive when under the influence
of alcohol or drugs (including prescription or
over-the-counter drugs which may cause
drowsiness). Always wear your seat belt as
outlined in the “Seat belts” (P.1-18), and also
instruct your passengers to do so.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash,
an unbelted or improperly belted person is
significantly more likely to be injured or killed than a person properly wearing a seat
belt.
ON-PAVEMENT AND OFF-ROAD
DRIVING PRECAUTIONS
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
They have higher ground clearance than
passenger cars to make them capable of
performing in a variety of on-pavement and
off-road applications. This gives them a
higher center of gravity than ordinary cars.
An advantage of higher ground clearance is
a better view of the road, allowing you to
anticipate problems. However, they are not
designed for cornering at the same speeds as
conventional passenger cars any more than
low-slung sports cars are designed to per-
form satisfactorily under off-road condi-
tions. If at all possible, avoid sharp turns or
abrupt maneuvers, particularly at high
speeds. As with other vehicles of this type,
failure to operate this vehicle correctly may
result in loss of control or vehicle rollover.
Seat belts help reduce the risk of injury in
collisions and rollovers. In a rollover crash, an
unbelted or improperly belted person is
significantly more likely to be injured or killed
than a person properly wearing a seat belt.
Be sure to read “Driving safety precautions”
(P.5-10).
