CAUTION
cDo not use the seat heater for extended
periods or when no one is using the
seat.
cDo not put anything on the seat which
insulates heat, such as a blanket, cush-
ion, seat cover, etc. Otherwise, the seat
may become overheated.
cDo not place anything hard or heavy on
the seat or pierce it with a pin or similar
object. This may result in damage to the
heater.
cAny liquid spilled on the heated seat
should be removed immediately with a
dry cloth.
cWhen cleaning the seat, never use
gasoline, benzine, thinner, or any simi-
lar materials.
cIf any abnormalities are found or the
heated seat does not operate, turn the
switch off and have the system checked
by your NISSAN dealer.
cThe battery could run down if the seat
heater is operated while the engine is
not running.The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system on for most driv-
ing conditions.
If the vehicle is stuck in mud or snow, the VDC
system reduces the engine output to reduce
wheel spin. The engine speed will be reduced
even if the accelerator is depressed to the floor. If
maximum engine power is needed to free a stuck
vehicle, turn the VDC system off.
To turn off the VDC system, push the VDC OFF
switch. The
indicator will come on.
Push the VDC OFF switch again or restart the engine
to turn on the system. See “Vehicle dynamic control
(VDC) system” in the “Starting and driving” section.
The Electronic Locking Rear Differential (E-Lock)
system can help provide added traction if the
vehicle is stuck or becoming stuck.
To activate the E-Lock system:
cthe 4WD switch must be in the 4LO position
(4-wheel drive vehicles) ,
cthe vehicle must be stopped or moving at 4
mph (7 km/h) or less, and
cthe E-Lock system switch must be turned
ON.
When the E-Lock switch is turned ON, the indi-
cator light will flash until the system engages.

are not met or the system becomes disengaged,
the indicator light will continue to flash.
The Anti-Lock Brake (ABS) system is disabled
and the ABS light illuminates when the E-Lock
system is ON. Also, the Vehicle Dynamic Control
(VDC) system is disabled and the VDC light
illuminates when the E-Lock system is ON.
See “Electronic locking rear differential (E-Lock)
system” in the “Starting and Driving” section for
further explanation and system limitations.
WARNING
cNever leave the E-Lock system ON
when driving on paved or hard-surfaced
roads. Turning the vehicle may result in
the rear wheels slipping and result in an
accident and personal injury. After us-
ing the E-Lock system to free the ve-
hicle, turn the system OFF.cUse the E-Lock system only when free-
ing a stuck vehicle. Try the 4LO position
before using the E-Lock system. Never
use the E-Lock system on a slippery
road surface such as snow or ice sur-
face. Using the E-Lock system when
driving in these road conditions may
cause unexpected movement of the ve-
hicle during engine braking, accelerat-
ing or turning, which may result in an
accident and serious personal injury.
CAUTION
cAfter using the E-Lock system, turn the
switch OFF to prevent possible damage
to driveline components from extended
use.
cDo not drive over 12 MPH (20 km/h)
when the system is engaged. Doing so
could result in possible damage to the
driveline.
cDo not turn on the E-lock system while
the tires are spinning. Doing so could
damage drivetrain components.
WARNING
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 rear sonar system is active when the ignition
is in the ON position and the shift selector lever is
in R (Reverse) .
When sensors detect obstacles within 6 ft (1.8
m) of the rear bumper, a beeping tone is emitted.
The rear sonar system can be disabled by push-
ing the OFF switch. When the system is disabled,

WARNING
cGasoline 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.
cDo 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.
cUse 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 to come on.
cNever pour fuel into the throttle body to
attempt to start your vehicle.cDo not fill a portable fuel container on a
truck bed liner, rubber truck bed mat, or
other insulating material. Static elec-
tricity can cause an explosion of flam-
mable 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
cOnly 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.
cIf fuel is spilled on the vehicle body,
flush it away with water to avoid paint
damage.cTighten until the fuel-filler cap clicks.
Failure to tighten the fuel-filler cap
properly may cause the
mal-
function indicator light (MIL) to illumi-
nate. If the
light illuminates be-
cause the fuel-filler cap is loose or
missing, tighten or install the cap and
continue to drive the vehicle.
The
light should turn off after a
few driving trips. If the
light
does not turn off after a few driving
trips, have the vehicle inspected by a
NISSAN dealer.

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:
cThe engine coolant temperature gauge will
move toward the H position.
cEngine power may be reduced.
cThe 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 malfunction indicator lamp may also come
ON. Ifonlyit remains on, you do not need to have
your vehicle towed, but have it inspected soon by
a NISSAN dealer. See “Malfunction indicator
lamp” in the “Warning and indicator lights” sec-
tion of this manual.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,
which could increase the chance of a col-
lision. Be especially careful when driving.
Pull to the side of the road to a safe area.
Allow the engine to cool and return to
normal operation. See “If your vehicle
overheats” in the “In case of emergency”
section of this manual.
CAUTION
Running the engine with the engine oil
pressure warning light on could cause se-
rious damage to the engine almost imme-
diately. Such damage is not covered by
warranty. Turn off the engine as soon as it
is safe to do so.

cWhen cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
c
Use 4H or 4L position only when
necessary. Four-wheel drive operation low-
ers fuel economy.
WARNING
cFor 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.
cDo 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.
CAUTION
cDo not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift
switch to 2WD.
– in the 4LO position, stop the vehicle,
