but it is not a substitute for proper
driving.
● The rear sonar system is a convenience
but it is not a substitute for proper back-
ing. Always turn and check that it is safe
to do so before backing up. Always
back up slowly. The front sonar system:
● is active when the ignition is in the ON
position and the shift selector is in a forward
gear position.
● a beeping tone is emitted when the sensors
detect obstacles within 3 ft (1.0 m) of the
front bumper.
The rear sonar system: ● is active when the ignition is in the ON
position and the shift selector is in R (Re-
verse) .
● a beeping tone is emitted when the sensors
detect obstacles within 5.9 ft (1.8 m) of the
rear bumper.

1Pull the hood lock release handle located
below the driver side instrument panel. The
hood will spring up slightly.
2Push the lever at the front of the hood to the
side as illustrated with your fingertips and
raise the hood.
When closing the hood, lower it slowly and make
sure it locks into place.
WARNING
● Make sure the hood is completely
closed and latched before driving. Fail-
ure to do so could cause the hood to fly
open and result in an accident.
● If you see steam or smoke coming from
the engine compartment, to avoid injury
do not open the hood.
WARNING
● Always be sure the lift gate has been
closed securely to prevent it from open-
ing while driving.
● Do not drive with the lift gate open. This
could allow dangerous exhaust gases
to be drawn into the vehicle. See “Ex-
haust gas” in the “Starting and driving”
section of this manual.
● Do not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
● Always be sure that hands and feet are
clear of the door frame to avoid injury
while closing the lift gate.

WARNING
Do not drive with the glass hatch open.
This could allow dangerous exhaust gases
to be drawn into the vehicle. See “Exhaust
gas” in the “Starting and driving” section
of this manual.
FUEL-FILLER CAP
WARNING
●Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
● Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off
automatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
● Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury. It could also cause
the
Malfunction Indicator Light
(MIL) to come on.
● Never pour fuel into the throttle body to
attempt to start your vehicle. ●
Do not fill a portable fuel container in
the vehicle or trailer. Static electricity
can cause an explosion of flammable
liquid, vapor or gas in any vehicle or
trailer. To reduce the risk of serious
injury or death when filling portable fuel
containers:
– Always place the container on the ground when filling.
– Do not use electronic devices when filling.
– Keep the pump nozzle in contact with the container while you are fill-
ing it.
– Use only approved portable fuel con- tainers for flammable liquid.
CAUTION
●Only vehicles with the E-85 filler door
label can operate on E-85. Fuel system
or other damage can occur if E-85 is
used in vehicles that are not designed
to run on E-85.

3-28Pre-driving checks and adjustments

●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.
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
them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to over-
heat 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,

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.
● Check that all doors are closed.
● Position seat and adjust head restraint and
headrests (if so equipped) .
● 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 placed in the ON posi-
tion. See “Warning/indicator lights and au-
dible reminders” in the “Instruments and
controls” section of this manual. 1. Apply the parking brake.
2. Move the shift selector to P (Park) or N
(Neutral) . P (Park) is recommended.
The shift selector cannot be moved out
of P (Park) and into any of the other
gear positions if the ignition switch is
turned to 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.
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.
● If the engine is very hard to start in ex-
tremely cold weather or when restarting,
depress the accelerator pedal a little (ap-
proximately 1/3 to the floor) and hold it
and then crank the engine. Release the
key and the accelerator pedal when the
engine starts.
BEFORE STARTING THE ENGINE STARTING THE ENGINE
Starting and driving5-13

●If the engine is very hard to start because
it is flooded, depress the accelerator
pedal all the way to the floor and hold it.
Crank the engine for 5 to 6 seconds. After
cranking the engine, release the accel-
erator pedal. Crank the engine with your
foot off the accelerator pedal by turn-
ing the ignition key to START. Release the
key when the engine starts. If the engine
starts, but fails to run, repeat the above
procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, turn the key off and wait 10
seconds before cranking again, otherwise
the starter could be damaged.
4. Allow the engine to idle for at least 30 sec- onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather.
In cold weather, keep the engine running for
a minimum of 2–3 minutes before shutting it
off. Starting and stopping the engine over a
short period of time may make the vehicle
more difficult to start.
ENGINE PROTECTION MODE
The engine has an engine protection mode to
reduce the chance of damage if the coolant tem-
perature becomes too high (for example, when
climbing steep grades in high temperature with
heavy loads, such as when towing a trailer) .
When the engine temperature reaches a certain
level: ● The engine coolant temperature gauge will
move toward the H position.
● Engine power may be reduced.
● The air conditioning cooling function may be
automatically turned OFF for a short time
(the blower will continue to operate) .
Engine power and, under some conditions, ve-
hicle speed will decrease. Vehicle speed can be
controlled with the accelerator pedal, but the
vehicle may not accelerate at the desired speed.
The transmission will downshift or upshift as it
reaches prescribed shift points. You can also
shift manually.
As driving conditions change and engine coolant
temperature is reduced, vehicle speed can be
increased using the accelerator pedal, and air
conditioning cooling function will automatically
be turned back ON. If:
1. The engine coolant temperature is not re- duced.
2. The air conditioning cooling function does not turn back ON.
3. The engine oil pressure warning/engine coolant temperature high indicator
il-
luminates, this may indicate a malfunction.
Move the vehicle off the road in a safe area
and allow the engine to cool. If after check-
ing the oil and coolant, the
remains
on, do not continue to drive and call a
NISSAN dealer.
The check engine light may also come ON. If
only it remains on, you do not need to have your
vehicle towed, but have it inspected soon by a
NISSAN dealer. See “Check engine light” in the
“Instruments and controls ” section of this
manual.
DRIVING THE VEHICLE

Shift lock release
If the battery is discharged, the shift selector may
not be moved from the P (Park) position even with
the brake pedal depressed.
To move the shift selector, release the shift lock.
The shift selector can be moved to N (Neutral) .
However, the steering wheel will be locked un-
less the ignition switch is placed in the ON posi-
tion (for models with a steering lock mechanism) .
This allows the vehicle to be moved if the battery
is discharged.To push the shift lock release, complete the fol-
lowing procedure:
1. Place the ignition switch in the LOCK posi- tion and remove the key.
2. Apply the parking brake.
3.
Remove the shift lock release cover as shown.
4. Use a protective cloth on the tip of a small screwdriver before inserting it in the shift
lock release slot and pushing down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
6. Place the ignition switch in the ON position to unlock the steering wheel (for models with
a steering lock mechanism) .
7. Now the vehicle may be moved to the de- sired location.
If the shift selector cannot be moved out of P
(Park) , have a NISSAN dealer check the auto-
matic transmission system as soon as possible.
WARNING
If the shift selector cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Fail-safe
When the fail-safe operation occurs, please note
that the transmission will be locked in any of the
forward gears according to the condition.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition
switch OFF and wait for 3 seconds. Then
turn the ignition switch back to the ON
position. The vehicle should return to its
normal operating condition. If it does not
