CAUTION
When engine speed approaches the
red zone, shif t to a higher gear or re-
duce engine speed. Operating the en-
gine in the red zone may cause serious
engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
NOTE:
The ignition switch must be placed in the
ON position for the gauge to give a
reading.
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range when the
reading is within the zone
OAshown in the
illustration. The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
CAUTION
If the gauge indicates a coolant tem-
perature near the hot (H) end of the
normal range, reduce vehicle speed to
decrease the temperature. If the gauge
is over the normal range, stop the ve-
hicle as soon as safely possible. If the
engine is overheated, continued opera-
tion of the vehicle may seriously dam-
age the engine. For additional informa-
tion, refer to “If your vehicle overheats”
in the “In case of emergency ” section
for immediate action required.

Cooling
This mode is used to cool and dehumidif y
the air.
1. Press the
button to the off position.
2. Press the
air flow control button.
3. Turn the
fan speed control dial to
the desired position.
4. Press the A/C button. The indicator light comes on.
5. Turn the temperature control dial to the desired position.
• For quick cooling when the outside tem- perature is high, press the
button to
the ON position. Be sure to return the
to the off position for normal cooling.
MAX A/C may be used for quick cooling.
Dehumidified heating
This mode is used to heat and dehumidif y
the air.
1. Press the
button to the off position.
2. Press the
air flow control button.
3. Turn the
fan speed control dial to
the desired position.
4. Press the A/C (air conditioner) button. The indicator light comes on. 5. Turn the temperature control dial to the
desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.
1. Press the
air flow control button.
2. Turn the
fan speed control dial to
the desired position.
• When the
orare selected, the
air conditioner automatically turns on if
the outside temperature is more than
36°F (2°C). This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further 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 prevent
damage to the system due to lack of lu-
brication.
• 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 temperature
over the normal range, turn the air condi-
tioner off. For additional information, refer
to “If your vehicle overheats” in the “In case
of emergency” section of this manual.
• When Remote Engine Start (if so equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.
4-36Monitor, 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 de-
froster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. 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 the previous climate setting was
turned off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, the air
flow outlet will return to previous settings,
and operation will continue normally. To
exit, press any climate control button.
• Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. • 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. 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, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
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 equip-
ment.

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, refer
to “Changing engine coolant” in the “Do-it-
yourself ” section of this manual.
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, refer to “Tire chains” in the
“Do-it-yourself ” section of this manual.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re-move ice and snow from the windows
and wiper blades.
• A sturdy, flat board to be placed under the jack to give it firm support.
• A shovel to dig the vehicle out of snow- drif ts.
• Extra washer fluid to refill the windshield- washer fluid reservoir.
DRIVING ON SNOW OR ICE
WARNING
• Wet ice (32°F, 0°C and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” un-
der these conditions. Try to avoid
driving on wet ice until the road is
salted or sanded.
• Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shif ting too fast, the drive wheels will
lose even more traction.
• Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry
pavement.
• Allow greater following distances on
slippery roads.
• Watch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while on
the ice, and avoid any sudden steer-
ing maneuvers.
5-126Starting and driving

•Do not use the cruise control (if so
equipped) on slippery roads.
• Snow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist
with cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F (-7°C)
or lower.
WARNING
• Do not use your engine block heater
with an ungrounded electrical sys-
tem or a 2-pronged adapter. You can
be seriously injured by an electrical
shock if you use an ungrounded
connection.
• Disconnect and properly store the
engine block heater cord before
starting the engine. Damage to the
cord could result in an electrical
shock and can cause serious injury. •
Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least 10 A.
Plug the extension cord into a
Ground Fault Interrupt (GFI) pro-
tected, grounded 110-VAC outlet.
Failure to use the proper extension
cord or a grounded outlet can result
in a fire or electrical shock and cause
serious personal injury.
To use the engine block heater:
1. Turn the engine off.
2. Open the hood and unwrap the engine block 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 least2-4hours, 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.
Starting and driving5-127

CAUTION
• Do not push start this vehicle. The
three-way catalyst may be
damaged.
• Continuously Variable Transmission
(CVT) models and Manual Transmis-
sion (M/T) cannot be push-started or
tow-started. Attempting to do so
may cause transmission damage.
• For Manual Transmission (M/T) mod-
els, never try to start the vehicle by
towing it. When the engine starts, the
forward surge could cause the ve-
hicle to collide with the tow vehicle. If your vehicle is overheating (indicated by
an extremely high temperature gauge
reading), or if you feel a lack of engine
power, detect abnormal noise, etc., take the
following steps.
WARNING
• Do not continue to drive if your ve-
hicle overheats. Doing so could cause
engine damage or a vehicle fire.
• To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
• Do not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, ap- ply the parking brake and move the shif t
lever to N (Neutral) (manual transmis-
sion) or to P (Park) (CVT).
Do not stop the engine.
2. Turn off the air conditioner (if so equipped). Open all the windows, move
the heater or air conditioner tempera-
ture control to maximum hot and fan
control to high speed. 3. Get out of the vehicle. Look and listen for
steam or coolant escaping from the ra-
diator before opening the hood. (If
steam or coolant is escaping, turn off
the engine.) Do not open the hood fur-
ther until no steam or coolant can be
seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
5. Visually check drive belts for damage or looseness. Also check if the cooling fan
is running. The radiator hoses and radia-
tor should not leak water. If coolant is
leaking, the water pump belt is missing
or loose, or the cooling fan does not run,
stop the engine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into con-
tact with, or get caught in, engine belts
or the engine cooling fan. The engine
cooling fan can start at any time.
