SPEEDOMETER AND ODOMETER
This vehicle is equipped with a speedom-
eter and odometer. The speedometer is
located on the right side of the meter clus-
ter. The odometer is located in the vehicle
information display to the lef t of the speed-
ometer and can be accessed with the ve-
hicle in the ON position.

TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev
the engine into the red zone
O1.
CAUTION
When engine speed approaches the
red zone, reduce engine speed. Operat-
ing the engine in the red zone may
cause serious engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range
O1when
the gauge needle points within the zone
shown in the illustration.
The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
CAUTION
If the gauge indicates coolant tem-
perature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease temperature. If the gauge is
over the normal range, stop the vehicle
as soon as safely possible. If the engine
is overheated, continued operation of
the vehicle may seriously damage the
engine. For additional information, see
“If your vehicle overheats” (P. 6-12) for
immediate action required.

When theorpositions are se-
lected, the air conditioner automatically
turns on if the outside temperature is more
than 36°F (2°C). The air conditioning system
will continue to operate until the
fan
speed control dial is turned to OFF, the air
conditioner is turned OFF, or the vehicle is
shut off. If a position other than the
front defrost air flow button is selected, the
A/C compressor will not turn off even if the
user had selected A/C off prior to entering
defrost. In
front defrost orfoot
defrost the indicator light on the A/C but-
ton will not turn on if the user had selected
A/C off. Turning off the air conditioning via
the A/C button is not allowed in this mode.
If the A/C button indicator was on when
entering this mode, and the A/C button is
selected in this mode, the A/C button indi-
cator will turn off, but the A/C compressor
will still be automatically enabled. This de-
humidifies the air which helps defog the
windshield. The
mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment to fur-
ther improve the defogging performance.
3. Turn the temperature control dial to the desired position.
Operating tips
• Keep the windows closed while the airconditioner is in operation.
• Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to vent
hot air from the passenger compart-
ment. Then, close the windows. This al-
lows the air conditioner to cool the inte-
rior more quickly.
• The air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
• A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
• If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, see “If your vehicle over-
heats” (P. 6-12).
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. For addi-
tional information on heating and cooling,
see “Heater and air conditioner (manual)”
(P. 4-29). The air recirculation (
) but-
ton should always be in the OFF position
for heating and defrosting.

mirror (if so equipped) defroster
switch
For additional information, see “Rear win-
dow and/or outside mirror (if so equipped)
defroster switch” (P. 2-42).
OPERATING TIPS
The sunload sensor (if so equipped)O1, lo-
cated on the top center of the instrument
panel, helps the system maintain a con-
stant temperature. Do not put anything on
or around this sensor.
•
When the climate system is in automatic
operation and the engine coolant tem-
perature and outside air temperature are
low, the air flow outlet may default to de-
froster mode for a maximum of 2 minutes
30 seconds. This is not a malfunction. Af ter
the engine coolant temperature warms up,
the air flow outlet will return to foot mode
and operation will continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when previous climate setting was sys-
tem off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, air flow
outlet will return to previous settings, and
operation will continue normally. To exit,
press any climate control button.
• Keep the windows closed while the air conditioner is in operation.

ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the
coolant temperature becomes too high
(for example, when climbing steep grades
in high temperatures with heavy loads,
such as when towing a trailer). When the
engine temperature reaches a certain
level:
• The engine coolant temperature gaugewill 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,
vehicle 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
downshif t or upshif t as it reaches pre-
scribed shif t points. You can also shif t
manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accel-
erator pedal, and the air conditioning cool-
ing function will automatically be turned
back on. The Malfunction Indicator Light (MIL) may
also come on if the engine coolant tem-
perature is not reduced or the air condi-
tioning cooling function does not turn back
on. If
only it remains on, you do not need to
have your vehicle towed, but have it in-
spected soon. It is recommended that you
visit a NISSAN dealer for this service. For
additional information, see “Malfunction In-
dicator Light (MIL)” (P. 2-20).
WARNING
Overheating can result in reduced en-
gine power and vehicle speed. The re-
duced speed may be lower than other
traffic, which could increase the chance
of a collision. Be especially careful
when driving. If the vehicle cannot
maintain a safe driving speed, pull to
the side of the road in a safe area. Allow
the engine to cool and return to normal
operation. For additional information,
see “If your vehicle overheats” (P. 6-12).
CAUTION
Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.
AUTOMATIC TRANSMISSION (A/T)
WARNING
• Do not depress the accelerator pedal
while shif ting from P (Park) or N (Neu-
tral) to R (Reverse) or D (Drive). Always
depress the brake pedal until shif ting
is completed. Failure to do so could
cause you to lose control and have an
accident.
• Cold engine idle speed is high, so use
caution when shif ting into a forward
or reverse gear before the engine has
warmed up.
• Never shif t to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
reversing. This could cause an acci-
dent or damage the transmission.
DRIVING THE VEHICLE
5-18Starting and driving

Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you consult a NISSAN dealer if the area
around the sonar sensors is damaged due
to a collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry key fob.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-6).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P. 8-16).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, see
“Changing engine coolant” (P. 8-6).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used. For additional information, see “Tire chains” (P. 8-35).
COLD WEATHER DRIVING
Starting and driving5-127

To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engineblock heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension
cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded
110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2–4 hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.NOTE:
When using the engine block heater
(if so equipped) on an Applied Vehicle
(engine block heater is plugged in):
• Vehicle should be parked on a levelsurface.
Or
• If a level surface is not available, thevehicle should be parked with the front
of the truck lower than the rear (nose
down).
CAUTION
Use of the engine block heater when
parked with the front of the vehicle
higher than the rear (5 degrees or
more) may cause the engine block
heater to become damaged and/or
inoperative.
