CAUTION
• Do not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce 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 over rich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if noticeable
loss of performance or other unusual op-
erating conditions are detected. Have
the vehicle inspected promptly. It is rec-
ommended that you visit an INFINITI re-
tailer 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 Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check all 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 driv-
er’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 approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illumi-
nated, the system may not be able to detect
or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea-
sons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels al-
low the TPMS to continue to function
properly.
Starting and driving5-5

Additional information:
• When replacing a wheel without the TPMSsuch as the spare tire, the TPMS does not
monitor the tire pressure of the spare tire.
• The TPMS will activate only when the ve- hicle 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 in-
flated 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 “Tire Pressure Low — Add Air” warning appears in the vehicle information display
when the low tire pressure warning light is
illuminated and low tire pressure is de-
tected. The “Tire Pressure Low - Add Air”
warning turns off when the low tire pres-
sure warning light turns off.
• The “Tire Pressure Low — Add Air” warning appears each time the ignition switch is in
the ON position as long as the low tire
pressure warning light remains illuminated. • The “Tire Pressure Low — Add Air” 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. Do not re-
duce the tire pressure after driving because
the tire pressure rises after driving. Low
outside temperature can lower the tem-
perature of the air inside the tire which can
cause a lower tire inflation pressure. This
may cause the low tire pressure warning
light to illuminate. If the warning light illu-
minates, check the tire pressure for all four
tires.
• The Tire and Loading Information label is located in the driver's door opening.
• You can also check the pressure of all tires (except the spare tire) on the vehicle infor-
mation display screen. The order of the tire
pressure figures displayed on the screen
corresponds with the actual order of the
tire position.
For additional information, see “Low tire
pressure warning light” (P. 2-13) and “Tire
Pressure Low — Add Air” (P. 2-24).WARNING
• Radio waves could adversely affect elec-
tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
• If the low tire pressure warning light illu-
minates 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 personal injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
off. If you have a flat tire, replace it with
a replacement tire as soon as possible.
(For additional information, see “Flat
tire” (P. 6-3) for changing a flat tire.)
5-6Starting and driving

•When replacing a wheel without the
TPMS such as the spare tire, when a
spare tire is mounted or a wheel is re-
placed, tire pressure will not be indi-
cated, the TPMS will not function and
the low tire pressure warning light will
flash for approximately 1 minute. The
light will remain on after 1 minute. Have
your tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
• 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 sig-
nals from the tire pressure sensors, and
the TPMS will not function properly. Some devices and transmitters may tempo-
rarily interfere with the operation of the
TPMS and cause the low tire pressure warn-
ing 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.
The low tire pressure warning light may illu-
minate 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.

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 recom-
mended 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 posi- tion. Do not start the engine.
Starting and driving5-7

Operation:
1. Add air to the tire.
2. After a few seconds, the hazard indicatorswill start flashing.
3. When the designated pressure is reached, the horn beeps once and the hazard indi-
cators stop flashing.
4. Perform the above steps for each tire. • If the tire is over-inflated more than ap-proximately 4 psi (30 kPa), the horn
beeps and the hazard indicators flash
three 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 pres-
sure, 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 TPMS with Tire Inflation Indi-
cator is not operating.
• The TPMS will not activate the TPMS with Tire Inflation Indicator under the
following conditions:– If there is interference from an exter- nal device or transmitter.
– The air pressure from the inflation de- vice is not sufficient to inflate the tire. – There is a malfunction in the TPMS.
– There is a malfunction in the horn or
hazard indicators.
– The identification code of the tire pressure sensor is not registered to
the system.
– The battery of the tire pressure sensor is low.
• If the TPMS with Tire Inflation Indicator does not operate due to TPMS interfer-
ence, move the vehicle about 3 ft (1 m)
backward or forward and try again.
If the TPMS with Tire Inflation Indicator is
not working, use a tire pressure gauge.
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 pas-
senger cars to make them capable of per-
forming in a variety of on-pavement and off-
road applications. This gives them a higher
center of gravity than ordinary vehicles. An
advantage of higher ground clearance is a
better view of the road, allowing you to an-
ticipate problems. However, they are not de-
signed for cornering at the same speeds as
conventional 2-Wheel Drive vehicles any
more than low-slung sports cars are de- signed to perform satisfactorily under off-
road conditions. If at all possible, avoid sharp
turns at high speeds. As with other vehicles of
this type, failure to operate this vehicle cor-
rectly may result in loss of control or vehicle
rollover. In a rollover crash, an unbelted per-
son is significantly more likely to die than a
person wearing a seat belt.
For additional information, see “Driving
safety precautions” (P. 5-10).
AVOIDING COLLISION AND
ROLLOVER
WARNING
Failure to operate this vehicle in a safe and
prudent manner may result in loss of con-
trol or an accident.
Be alert and drive defensively at all times.
Obey all traffic regulations. Avoid excessive
speed, high speed cornering, or sudden steer-
ing maneuvers, because these driving prac-
tices could cause you to lose control of your
vehicle.
As with any vehicle, loss of control could re-
sult in a collision with other vehicles or ob-
jects or cause the vehicle to roll over, par-
ticularly if the loss of control causes the
vehicle to slide sideways.
5-8Starting and driving

Be attentive at all times, and avoid driving
when tired. Never drive when under the influ-
ence of alcohol or drugs (including prescrip-
tion or over-the-counter drugs which may
cause drowsiness). Always wear your seat
belt as outlined in the “Safety – Seats, seat
belts and supplemental restraint system” sec-
tion of this manual, 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 person is significantly more likely
to die than a person wearing a seat belt.
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 wheel with both hands and try to hold a straight
course. 4. When appropriate, slowly release the ac-
celerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while vehicle
speed is reduced. Do not attempt to drive
the vehicle back onto the road surface
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,
gradually 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 han-
dling and stability of the vehicle, especially at
highway speeds. Help prevent rapid air pressure loss by main-
taining the correct air pressure and visually
inspecting the tires for wear and damage. For
additional information, see “Wheels and tires”
(P. 8-27). 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 gen-
eral guide. The vehicle must be driven as ap-
propriate based on the conditions of the ve-
hicle, 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.
Starting and driving5-9

3. When appropriate, slowly release the ac-celerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe loca- tion off the road and away from traffic if
possible.
5. Lightly apply the brake pedal to gradually stop the vehicle.
6. Turn on the hazard warning flashers and contact a roadside emergency service to
change the tire. For additional informa-
tion, see “Flat tire” (P. 6-3).
DRINKING ALCOHOL/DRUGS
AND DRIVING
WARNING
Never drive under the influence of alcohol
or drugs. Alcohol in the bloodstream re-
duces coordination, delays reaction time
and impairs judgement. Driving after
drinking alcohol increases the likelihood of
being involved in an accident injuring your-
self and others. Additionally, if you are in-
jured in an accident, alcohol can increase
the severity of the injury. INFINITI is committed to safe driving. How-
ever, you must choose not to drive under the
influence of alcohol. Every year thousands of
people are injured or killed in alcohol-related
accidents. Although the local laws vary on
what is considered to be legally intoxicated,
the fact is that alcohol affects all people dif-
ferently and most people underestimate the
effects of alcohol.
Remember, drinking and driving don't mix!
And that is true for drugs, too (over-the-
counter, prescription, and illegal drugs). Don't
drive if your ability to operate your vehicle is
impaired by alcohol, drugs, or some other
physical condition.
DRIVING SAFETY PRECAUTIONS
Your INFINITI is designed for both normal
and off-road use. However, avoid driving in
deep water or mud as your INFINITI is mainly
designed for leisure use, unlike a conventional
off-road vehicle.
Remember that 2-Wheel Drive (2WD) mod-
els are less capable than All-Wheel Drive
(AWD) models for rough road driving and
extrication when stuck in deep snow or mud,
or the like.
Please observe the following precautions:
WARNING
• Spinning the front wheels on slippery
surfaces may cause the AWD warning
message to display and the AWD system
to automatically switch from the AWD
to the 2WD mode. This could reduce the
traction. Be especially careful when tow-
ing a trailer (AWD models).
• Drive carefully when off the road and
avoid dangerous areas. Every person
who drives or rides in this vehicle should
be seated with their seat belt fastened.
This will keep you and your passengers in
position when driving over rough terrain.
• Do not drive across steep slopes. Instead
drive either straight up or straight down
the slopes. Off-road vehicles can tip over
sideways much more easily than they can
forward or backward.
• Many hills are too steep for any vehicle.
If you drive up them, you may stall. If you
drive down them, you may not be able to
control your speed. If you drive across
them, you may roll over.
• Do not shift gears while driving on
downhill grades as this could cause loss
of control of the vehicle.
5-10Starting and driving

•Stay alert when driving to the top of a
hill. At the top there could be a drop-off
or other hazard that could cause an
accident.
• If your engine stalls or you cannot make
it to the top of a steep hill, never attempt
to turn around. Your vehicle could tip or
roll over. Always back straight down in R
(Reverse) gear and apply brakes to con-
trol your speed.
• Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an acci-
dent. Apply brakes lightly and use a low
gear to control your speed.
• Unsecured cargo can be thrown around
when driving over rough terrain. Prop-
erly secure all cargo so it will not be
thrown forward and cause injury to you
or your passengers.
• Secure heavy loads in the cargo area as
far forward and as low as possible. Do
not equip the vehicle with tires larger
than specified in this manual. This could
cause your vehicle to roll over. •
Do not grip the inside or spokes of the
steering wheel when driving off-road.
The steering wheel could move suddenly
and injure your hands. Instead drive with
your fingers and thumbs on the outside
of the rim.
• Before operating the vehicle, ensure that
the driver and all passengers have their
seat belts fastened.
• Always drive with the floor mats in place
as the floor may become hot.
• Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your INFINITI is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
• Do not drive beyond the performance ca-
pability of the tires, even with AWD
engaged.
• For AWD equipped vehicles, do not at-
tempt to raise two wheels off the ground
and shift the transmission to any drive or
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 dyna-
mometer (such as the dynamometers
used by some states for emissions test-
ing) or similar equipment even if the
other two wheels are raised off the
ground. Make sure you inform test facil-
ity personnel that your vehicle is
equipped with AWD before it is placed
on a dynamometer. Using the wrong test
equipment may result in drivetrain dam-
age or unexpected vehicle movement
which could result in serious vehicle dam-
age or personal injury.
• When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
• Accelerating quickly, sharp steering ma-
neuvers or sudden braking may cause
loss of control.
• If at all possible, avoid sharp turning ma-
neuvers, particularly at high speeds.
Your INFINITI vehicle has a higher center
of gravity than a passenger car. The ve-
hicle is not designed for cornering at the
same speeds as passenger cars. Failure
to operate this vehicle correctly could re-
sult in loss of control and/or a rollover
accident.
