a wireless connection to your phone.
SPEAKER ADAPTATION (SA) MODE
Speaker Adaptation allows up to two out-of-
dialect users to train the system to improve rec-
ognition accuracy. By repeating a number of
commands, the users can create a voice model of
their own voice that is stored in the system. The
system is capable of storing a different speaker
adaptation model for each connected phone.
Training procedure
The procedure for training a voice is as follows.1. Position the vehicle in a reasonably quiet outdoor location.
2. Sit in the driver’s seat with the engine run- ning, the parking brake on, and the transmis-
sion in P (Park) . 3. Press and hold the
button for more

4. The system announces: “Press the PHONE/SEND (
) button for the
hands-free phone system to enter the
speaker adaptation mode or press the
PHONE/END (
) button to select a dif-
ferent language.”
5. Press the
button.
For information on selecting a different lan-
guage, see “Choosing a language” in this
section.
6. Voice memory A or memory B is selected automatically. If both memory locations are
already in use, the system will prompt you to
overwrite one. Follow the instructions pro-
vided by the system.
7. When preparation is complete and you are ready to begin, press the
button.
8. The SA mode will be explained. Follow the instructions provided by the system.
9. When training is finished, the system will tell you an adequate number of phrases have

WARNING
●Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or col-
lision, unsecured cargo could cause
personal injury.
EXHAUST GAS (carbon monoxide)
WARNING
●Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is danger-
ous. It can cause unconsciousness or
death. ●
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle
inspected immediately.
● Do not run the engine in closed spaces
such as a garage.
● Do not park the vehicle with the engine
running for any extended length of time.
● Keep the lift gate and rear windows
closed while driving, otherwise exhaust
gases could be drawn into the passen-
ger compartment. If you must drive with
the lift gate or rear windows open, fol-
low these precautions:
1. Open all the windows.
2. Set the
air recirculation but-
ton to off and the fan control dial to
high to circulate the air.
● If electrical wiring or other cable con-
nections must pass to a trailer through
the seal on the lift gate or the body,
follow the manufacturer’s recommen-
dation to prevent carbon monoxide en-
try into the vehicle.
● The exhaust system and body should be
inspected by a qualified mechanic
whenever: a. The vehicle is raised for service.
b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the three-way catalyst are burned at
high temperatures to help reduce pollutants.
WARNING
●The exhaust gas and the exhaust sys-
tem are very hot. Keep people, animals
or flammable materials away from the
exhaust system components.
● Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-2Starting and driving

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 overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
● 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.
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 passen-
ger 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 two-wheel drive vehicles any more
than low-slung sports cars are designed to per-
form 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 correctly may result in loss of control
or vehicle rollover. In a rollover crash, an unbelted
person is significantly more likely to die than a
person wearing a seat belt.
Be sure to read the driving safety precautions
later in this section.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided) ,
should be checked monthly when cold and in-
flated 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 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
all 4 tires 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.

NISSAN 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. Al-
though 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, pre-
scription, and illegal drugs) . Don’t drive if your
ability to operate your vehicle is impaired by alco-
hol, drugs, or some other physical condition.
DRIVING SAFETY PRECAUTIONS
Your NISSAN is designed for both normal and
off-road use. However, avoid driving in deep wa-
ter or mud as your NISSAN is mainly designed for
leisure use, unlike a conventional off-road ve-
hicle.
Remember that two-wheel drive models are less
capable than four-wheel drive models for rough
road driving and extrication when stuck in deep
snow or mud, or the like.Please observe the following precautions:
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. In-
stead 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.
● 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 at-
tempt to turn around. Your vehicle
could tip or roll over. Always back
straight down in R (Reverse) gear. Never
back down in N (Neutral) or with the
clutch depressed (manual transmission
vehicles) , 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 acci-
dent. Apply brakes lightly and use a low
gear to control your speed. Use the hill
descent control feature (if so
equipped) .
● 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.
5-8Starting and driving

●To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack/gear bin (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as pos-
sible. 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 sud-
denly 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 NISSAN is more af-
fected 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 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 ve-
hicle 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 unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
● 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 NISSAN four-wheel drive vehicle
has a higher center of gravity than a
passenger car. The vehicle is not de-
signed for cornering at the same speeds
as 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 immedi-
ately 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 “Periodic mainte-
nance” in the “NISSAN Service and
Maintenance Guide.”
Starting and driving5-9

There is an OFF position between the
LOCK and ON positions. The OFF position
is indicated by a “1” on the ignition switch.
When the ignition is in the OFF position,
the steering wheel is not locked (for mod-
els with a steering lock mechanism) .
In order for the steering wheel to be locked, it
must be turned about 1/8 of a turn clockwise
from the straight up position.
To lock the steering wheel, turn the key to
the LOCK position. Remove the key. To
unlock the steering wheel, insert the key
and turn it gently while rotating the steer-
ing wheel slightly right and left.
If the key will not turn from the LOCK posi-
tion, turn the steering wheel to the left or
right while turning the key to unlock the
key cylinder.
MANUAL TRANSMISSION (if so
equipped)
The ignition switch includes a device that helps
prevent accidental removal of the key while driv-
ing.
The key can only be removed when the ignition
switch is in the LOCK position.
On manual transmission models, to turn the igni-
tion switch to the LOCK position from the ACC or
ON position, place the ignition switch in the OFF
position, push the key in, then place the ignition
switch in LOCK position.
KEY POSITIONS
LOCK: Normal parking position (0)
OFF: (Not used) (1)
ACC: (Accessories) (2)
This position activates electrical accessories
such as the radio when the engine is not running.
ON: Normal operating position (3)
This position turns on the ignition system and the
electrical accessories.
START: (4)
This position starts the engine. As soon as the
engine has started, release the key. It automati-
cally returns to the ON position.

NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer system will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedure:1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately 10
seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, NISSAN rec-
ommends placing the registered key on a sepa-
rate key ring to avoid interference from other
devices. ●
Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid, and windshield-washer fluid
as frequently as possible, or at least when-
ever you refuel.
● Check that all windows and lights are clean.
● Visually inspect tires for their appearance
and condition. Also check tires for proper
inflation.
● Lock all doors.
● Position seat and adjust head restraints.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.
● Check the operation of warning lights when
the ignition switch is turned to the ON (3)
position. See “Warning/indicator lights and
audible reminders” in the “Instruments and
controls” section of this manual. 1. Apply the parking brake.
2.
Automatic transmission:
Move the shift selector to P (Park) or N
(Neutral) . P (Park) is recommended.
The shift selector cannot be moved out
of the P (Park) position and into any of
the other gear positions if the ignition
switch is placed in the OFF position or
if the key is removed from the ignition
switch.
The starter is designed not to operate if
the shift selector is in any of the driving
positions.
Manual transmission:
Move the shift selector to N (Neutral) . De-
press the clutch pedal to the floor while
cranking the engine.
The starter is designed not to operate
unless the clutch pedal is fully de-
pressed.
3. Crank the engine with your foot off the
accelerator pedal by placing the ignition
switch in the START position. Release the
key when the engine starts. If the engine
starts, but fails to run, repeat the above
procedure.
