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 electrical sys-
tems 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 retailer.
● 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 recommended
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 pres-
sure 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 all 4 tires as soon as
possible, and inflate them to the proper pres-
sure. 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 combined with the low
tire pressure telltale. When the system detects
a malfunction, the telltale will flash for approxi-
mately one minute and then remain continu-
ously illuminated. 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.
Starting and driving5-3

Additional information
●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 not detect a sudden
drop in tire pressure (for example a flat tire
while driving).
● The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h) to
activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
● The CHECK TIRE PRESSURE warning appears
in the dot matrix liquid crystal display when
the low tire pressure warning light is illumi-
nated and low tire pressure is detected. The
CHECK TIRE PRESSURE warning turns off
when the low tire pressure warning light
turns off.
The CHECK TIRE PRESSURE warning does not
appear if the low tire pressure warning light
illuminates to indicate a TPMS malfunction. ●
Tire pressure rises and falls depending on
the heat caused by the vehicle’s operation
and the outside temperature. Low outside
temperature can lower the temperature of
the air inside the tire which can cause a
lower tire inflation pressure. This may cause
the low tire pressure warning light to illumi-
nate. If the warning light illuminates in low
ambient temperature, check the tire pres-
sure for all four tires.
● You can also check the pressure of all tires
(except the spare tire) on the display screen.
The order of the tire pressure figures dis-
played on the screen does not correspond
with the actual order of the tire position. See
“TIRE PRESSURE information” in the “4.
Monitor, climate, audio, phone and voice
recognition systems” section.
For additional information, see “Low tire pres-
sure warning light” in the “2. Instruments and
controls” section and “TIRE PRESSURE MONI-
TORING SYSTEM (TPMS)” in the “6. In case of
emergency” section.
WARNING
●If the low tire pressure warning light illumi-
nates or LOW PRESSURE information is dis-
played on the monitor screen while driving,
avoid sudden steering maneuvers or abrupt
braking, reduce vehicle speed, pull off the
road to a safe location and stop the vehicle as
soon as possible. Driving with under-inflated
tires may permanently damage the tires and
increase the likelihood of tire failure. Serious
vehicle damage could occur and may lead to
an accident and could result in serious per-
sonal injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the rec-
ommended COLD tire pressure shown on the
Tire and Loading Information label to turn the
low tire pressure warning light OFF. If the light
still illuminates while driving after adjusting
the tire pressure, a tire may be flat. If you have
a flat tire, replace it with a spare tire as soon as
possible. (See “FLAT TIRE” in the “6. In case of
emergency” section for changing a flat tire.)
● When a spare tire is mounted or a wheel is
replaced, the TPMS will not function and the
low tire pressure warning light will flash for
approximately 1 minute. The light will re-
main on after 1 minute. Contact your INFINITI
retailer as soon as possible for tire replace-
ment and/or system resetting.
5-4Starting and driving

●Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
● Do not inject any tire liquid or aerosol tire
sealant into the tires, as this may cause a
malfunction of the tire pressure 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 reception of the signals from
the tire pressure sensors, and the TPMS will
not function properly.
Some devices and transmitters may temporarily
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.

TPMS with Tire Inflation Indicator
When tire pressure is low, the low tire pressure
warning light illuminates.
This vehicle provides visual and audible signals
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 selector lever in the P (Park) position.
3. Place the ignition switch in the ON posi- tion. Do not start the engine.
Operation:
1. Add air to the tire.
2. In a few seconds, the hazard indicators 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 approxi-
mately 4 psi (30 kPa), the horn beeps and
the hazard indicators flash 3 times. To cor-
rect the pressure, push the core of the valve
stem on the tire briefly to release pressure.
Starting and driving5-5

When the pressure reaches the designated
pressure, the horn beeps once.
● If the hazard indicator does not flash in
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 is not sufficient to inflate the tire
– There is a malfunction in the TPMS sys- tem
– There is a malfunction in the horn or hazard indicators
● If the Tire Inflation Indicator does not oper-
ate 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 ma-
neuvers, 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 side-
ways. Be attentive at all times, and avoid
driving when tired. Never drive when under the
influence of alcohol or drugs (including pre-
scription or over-the-counter drugs which may
cause drowsiness). Always wear your seat belt
as outlined in the “SEAT BELTS” in the “1. Safety
— Seats, seat belts and supplemental restraint
system” section of this manual, and also in-
struct 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 signifi- cantly 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 roll-
over rate than other types of vehicles.
They have higher ground clearance than pas-
senger cars to make them capable of perform-
ing 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. How-
ever, they are not designed for cornering at the
same speeds as conventional passenger cars
any more than low-slung sports cars are de-
signed to perform satisfactorily under off-road
conditions. 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 PRECAU-
TIONS” later in this section.

OFF-ROAD RECOVERY
While driving, the right side or left side wheels
may unintentionally leave the road surface. If
this occurs, maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
1. Remain calm and do not overreact.
2. Do not apply the brakes.
3. Maintain a firm grip on the steering wheelwith both hands and try to hold a straight
course.
4. When appropriate, slowly release the ac- celerator pedal to gradually slow the ve-
hicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the ve-
hicle speed is reduced. Do not attempt to
drive the vehicle back onto the road sur-
face until vehicle speed is reduced. 6. When it is safe to do so, gradually turn
the steering wheel until both tires return
to the road surface. When all tires are on
the road surface, steer the vehicle to stay
in the appropriate driving lane.
●If you decide that it is not safe to return
the vehicle to the road surface based on
vehicle, road or traffic conditions, gradu-
ally slow the vehicle to a stop in a safe
place off the road.
RAPID AIR PRESSURE LOSS
Rapid air pressure loss or a “blow-out” can
occur if the tire is punctured or is damaged due
to hitting a curb or pothole. Rapid air pressure
loss can also be caused by driving on under-
inflated tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially at high-
way speeds.
Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspect the tires for wear and damage. See
“WHEELS AND TIRES” in the “8. Maintenance
and do-it-yourself” section of this manual. If a tire rapidly loses air pressure or “blows-out”
while driving maintain control of the vehicle by
following the procedure below. Please note that
this procedure is only a general guide. The
vehicle must be driven as appropriate based on
the conditions of the vehicle, road and traffic.
WARNING
The following actions can increase the chance
of losing control of the vehicle if there is a
sudden loss of tire air pressure. Losing control
of the vehicle may cause a collision and result
in personal injury.
●
The vehicle generally moves or pulls in the
direction of the flat tire.
● Do not rapidly apply the brakes.
● Do not rapidly release the accelerator pedal.
● Do not rapidly turn the steering wheel.
1. Remain calm and do not overreact.
2. Maintain a firm grip on the steering wheel
with both hands and try to hold a straight
course.
3. When appropriate, slowly release the ac- celerator pedal to gradually slow the ve-
hicle.

LANE DEPARTURE PREVENTION (LDP)
SYSTEM
Precautions on LDP system
WARNING
●The LDP system will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely, keep
the vehicle in the traveling lane, and be in
control of vehicle at all times.
● The LDP system is primarily intended for use
on well-developed freeways or highways. It
may not detect the lane markers in certain
roads, weather or driving conditions.
● Using the LDP system under some condi-
tions of road, lane marker or weather, or
when you change lanes without using the
lane change signal could lead to an unex-
pected system operation. In such condi-
tions, you need to correct the vehicle’s direc-
tion with your steering operation to avoid
accidents.
● When the LDP system is operating, avoid
excessive or sudden steering maneuvers.
Otherwise, you could lose control of the
vehicle. ●
The LDP system will not operate at speeds
below approximately 45 MPH (70 km/h) or if
it cannot detect lane markers.
● The LDP system may not function properly
under the following conditions, and do not
use the LDP system:
– During bad weather (rain, fog, snow, wind, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving off-road such as on sand or rock, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire condi- tions (for example, tire wear, low tire
pressure, installation of spare tire, tire
chains, non-standard wheels).
– When the vehicle is equipped with non- original brake parts or suspension parts.
– When towing a trailer or other vehicle. ●
If the LDP system malfunctions, it will cancel
automatically. The lane departure warning
light (orange) on the instrument panel will
illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the warning light
(orange) continues to illuminate, have the
LDP system checked by an INFINITI retailer.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The functions of the LDP system (warning and
brake control assist) may or may not operate
properly under the following conditions:
● On roads where there are multiple parallel
lane markers; lane markers that are faded or
not painted clearly; yellow painted lane
markers; non-standard lane markers; or lane
markers covered with water, dirt, snow, etc.
● On roads where discontinued lane markers
are still detectable.
