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.

METERS AND GAUGES
2-4Instruments and controls

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. 6-13) for
immediate action required.

Maintenance
The maintenance menu allows the user to set reminders for various vehicle maintenance items.
Some menu items shown below may not be equipped on your vehicle.
WARNING
The tire replacement indicator is not a substitute for regular tire checks, including tire pressure checks. For additional informa-
tion, see “Changing wheels and tires” (P. 8-41). Many factors including tire inflation, alignment, driving habits and road conditions
affect tire wear and when tires should be replaced. Setting the tire replacement indicator for a certain driving distance does not
mean your tires will last that long. Use the tire replacement indicator as a guide only and always perform regular tire checks.
Failure to perform regular tire checks, including tire pressure checks could result in tire failure. Serious vehicle damage could
occur and may lead to a collision, which could result in serious personal injury or death.
Menu item Explanation
Maintenance Allows user to cycle through various maintenance items and set reminders to perform maintenance at
specific intervals.
Oil and Filter Allows user to set an oil and filter reminder at a specific interval or reset the current one.
Air Filter Allows user to set an air filter reminder at a specific interval or reset the current one.
Tire Allows user to set a tire reminder at a specific interval or reset the current one.
Brake Pad Allows user to set a brake pad reminder at a specific interval or reset the current one.
Brake Fluid Allows user to set a brake fluid reminder at a specific interval or reset the current one.

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. 6-13).
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.
4-34Monitor, climate, audio, phone and voice recognition systems

• When the climate system is in automaticoperation and the engine coolant tem-
perature and outside air temperature
are low, the air flow outlet may default to
defroster mode for approximately 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant tempera-
ture 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. • If you feel that the air flow mode you have
selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction.
• When the ignition is placed in the ON po- sition, in some fogging or high cabin
temp conditions, air may flow automati-
cally to the foot outlets for 3 to 7 seconds
to purge the hot air in the system. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth's ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, see “Air conditioner system
refrigerant and oil recommendations”
(P. 10-8).
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly” air conditioning system.
WARNING
The
air conditioner system contains re-
frigerant under high pressure. To avoid
personal injury, any air conditioner ser-
vice should be done only by an experi-
enced technician with proper equipment.

In preparation for the next engine start, the
engine may have a slightly delayed shutoff
af ter placing the ignition switch in the
OFF position, depending on the driving
conditions.
NOTE:
The engine would NOT start within 3 sec-
onds of turning the engine off.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-tronic accessories that consume bat-
tery power when the engine is not
running (phone chargers, GPS, DVD
players, etc.).
2. The vehicle is not driven regularly and/or only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the Remote Engine
Start require the ignition switch to be
placed in the ON position before the shif t
lever can be moved from the P (Park) posi-
tion. To place the ignition switch in the ON
position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Push the ignition switch once to the ON position.
For additional information, see “NISSAN In-
telligent Key®” (P. 3-2).
ENGINE PROTECTION MODE
The engine has an engine protection mode
to reduce the chance of damage if the cool-
ant temperature becomes too high (for ex-
ample, when climbing steep grades in high
temperatures with heavy loads, such as
when towing a trailer). When the engine tem-
perature 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,
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 down-
shif t or upshif t as it reaches prescribed 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.
