How to speak numbers:
INFINITI Voice Recognition requires a cer-
tain way to speak numbers when giving
voice commands. Refer to the following
examples.
General rule
Only single digits 0 (zero) to 9 can be used.
(For example, if you would like to say 500,
“five zero zero” can be used, but “five
hundred” cannot. Phone numbers
Speak phone numbers according to the
following examples:
.
1-800-662-6200
—“ Dial one eight zero zero six six two
six two zero zero.”
Note 1: For the best voice recognition
phone dialing results, say phone numbers
as single digits.
Note 2: You cannot say 555-6000 as “five
five five six thousands” .
Note 3: When speaking a house number,
speak the number “0”as“zero”. If the
letter “o (Oh)” is included in the house
number, it will not be recognized as the
number “0 (zero)” even if you speak “oh”
instead of “zero”. Please speak “zero”for
the number “0 (zero)”,“oh”for the letter
“o (oh)”.
Send digits using dial tone: . Press the TALK
switch during a
phone call.
. The menu will be launched and you will
be provided with the following gui-
dance: "Please say the digits to dial".
. After guidance, say the digits of the
number you want to send. After this, the digits that have been recognized
will be read out.
. If you press the ENTER button on the
steering wheel or on the INFINITI con-
troller, the selected digits will be sent.

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 illuminated 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
appears each time the ignition switch
is placed in the ON position as long as the low tire pressure warning light
remains illuminated.
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 illuminate. If
the warning light illuminates in low
ambient temperature, check the tire
pressure 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 displayed 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
pressure warning light” in the“2. Instru-
ments and controls” section and“Tire Pressure Monitoring System (TPMS)
”in
the “6. In case of emergency” section.
WARNING
.If the low tire pressure warning light
illuminates or LOW PRESSURE informa-
tion is displayed 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 fail-
ure. 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 recommended
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
Starting and driving5-5

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
— 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 ROLL-
OVER
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 exces-
sive 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 drowsi-
ness). Always wear your seat belt as
outlined in the “Seat belts”in the“1.
Safety —seats, seat belts and supple-
mental restraint system” section 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 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
perform satisfactorily under off-road con-
ditions. 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 condi-
tions 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 accelerator pedal to gradually slow the
vehicle.
5. If there is nothing in the way, steer the vehicle to follow the road while the
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 vehi-
cle 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 highway speeds.
Help prevent rapid air pressure loss by
maintaining 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 condi-

tions 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 accelerator pedal to gradually slow the
vehicle.
4. Gradually steer the vehicle to a safe location off the road and away from
traffic if possible. 5. Lightly apply the brake pedal to gradu-
ally stop the vehicle.
6. Turn on the hazard warning flashers and either contact a roadside emer-
gency service to change the tire or see
“Changing a flat tire” in the“6. In case
of emergency” section of this Owner’s
Manual.
DRINKING ALCOHOL/DRUGS AND
DRIVING
WARNING
Never drive under the influence of alcohol or
drugs. Alcohol in the bloodstream reduces
coordination, delays reaction time and im-
pairs judgement. Driving after drinking
alcohol increases the likelihood of being
involved in an accident injuring yourself and
others. Additionally, if you are injured in an
accident, alcohol can increase the severity
of the injury.
INFINITI is committed to safe driving.
However, 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 differently 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 Two-Wheel Drive (2WD)
models are less capable than Four-Wheel
Drive (4WD) models for rough road driving
and extrication when stuck in deep snow,
mud, or the like.
Please observe the following precautions:
Starting and driving5-9

5-10Starting and driving
WARNING
.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 ranges while driving on
downhill grades as this could cause loss
of control of the vehicle.
. 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) range. Never back down in N
(Neutral), using only the brake, as this
could cause loss of control.
. Heavy braking going down a hill could
cause your brakes to overheat and fade,
resulting in loss of control and an
accident. Apply brakes lightly and use
a low range 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.
. To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so equipped)
and evenly distribute the load. 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 became hot.
. Lower your speed when encountering
strong crosswinds. With a higher center
of gravity, your INFINITI is more affected
by strong side winds. Slower speeds
ensure better vehicle control.
. Do not drive beyond the performance
capability of the tires, even with 4WD
engaged.
. For 4WD equipped vehicles, do not
attempt 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 a 4WD 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 4WD 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 (4WD
models).
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
. Accelerating quickly, sharp steering
maneuvers or sudden braking may cause
loss of control.
. If at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your vehicle has a higher center of
gravity than a conventional passenger
car. The vehicle is not designed for
cornering at the same speeds as con-
ventional passenger cars. Failure to
operate this vehicle correctly could
result in loss of control and/or a rollover
accident.
. 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.
. Be sure to check the brakes immediately
after driving in mud or water. See “Brake
system” later in this section for wet
brakes.
. Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or sideways,
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
information in the “INFINITI Service and
Maintenance Guide”.
. Spinning the rear wheels on slippery
surfaces may cause the 4WD warning
light to flash. The 4WD system may also
automatically switch from the 4WD
mode to the 2WD mode. This could
reduce traction. Be especially 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.

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 responsibility 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 high-
ways. It may not detect the lane markers
in certain roads, weather or driving
conditions.
. Using the LDP system under some
conditions of road, lane marker or
weather, or when you change lanes
without using the lane change signal
could lead to an unexpected system
operation. In such conditions, you need
to correct the vehicle’s direction with
your steering operation to avoid acci-
dents. .
When the LDP system is operating, avoid
excessive or sudden steering maneu-
vers. 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 toroad repairs.
—When driving in a makeshift lane.
—When driving on roads where thelane width is too narrow.
—When driving without normal tireconditions (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 suspen-
sion parts.
—When towing a trailer or othervehicle.
. 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 location 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
warning 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 con-
ditions:

5-28Starting and driving
the vehicle to the center of the traveling
lane.
The warning and assist functions will stop
when the vehicle returns to a position
inside of the lane marker.
