TACHOMETER
The tachometer indicates engine speed in
revolutions per minute (rpm). Do not rev
the engine into the red zone
1.
CAUTION
When engine speed approaches the red
zone, reduce engine speed. Operating
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
1when
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 tempera-
ture 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 over-
heated, continued operation of the ve-
hicle may seriously damage the engine.
For additional information, refer to “If
your vehicle overheats” in the “In case
of emergency ” section of this manual
for immediate action required.

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 com-
partment. Then, close the windows.
This allows the air conditioner to cool
the interior 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 in-
formation, refer to “If your vehicle over-
heats” 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.
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. The
air
recirculation button should always be in
the off position for heating and defrost-
ing.
Monitor, climate, audio, phone and voice recognition systems4-33

∙ When the climate system is in auto-matic operation and the engine coolant
temperature and outside air tempera-
ture are low, the air flow outlet may de-
fault to defroster 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 out-
let will return to foot mode and opera-
tion will continue normally.
∙ When the outside and interior cabin temperatures are moderate to high, the
intake 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 oc-
cur 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 con-
trol 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 out-
lets 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 conditioner 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.

∙ Make sure the area around the vehicle isclear.
∙ Check fluid levels such as engine oil, coolant, brake fluid, and windshield-
washer fluid as frequently as possible,
or at least whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appear- ance and condition. Also check tires for
proper inflation.
∙ Lock all doors.
∙ Position seat and adjust headrests/head restraints.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passen- gers to do likewise.
∙ Check the operation of warning lights when the ignition switch is pushed to
the ON position. For additional informa-
tion, refer to “Warning lights, indicator
lights and audible reminders” in the “In-
struments and controls” section of this
manual. 1. Apply the parking brake.
2. Move the shif t lever to P (Park) or N
(Neutral). P (Park) is recommended.
The starter is designed not to oper-
ate if the shif t lever is in any of the
driving positions.
3. Push the ignition switch to the ON po- sition. Depress the brake pedal and
push the ignition switch to start the
engine.
To start the engine immediately, push
and release the ignition switch while
depressing the brake pedal with the
ignition switch in any position.
∙ If the engine is very hard to start in extremely cold weather or when re-
starting, depress the accelerator
pedal a little (approximately 1/3 to the
floor) and while holding, crank the en-
gine. Release the accelerator pedal
when the engine starts.
∙ If the engine is very hard to start be- cause it is flooded, depress the accel-
erator pedal all the way to the floor
and hold it. Push the ignition switch
to the ON position to start cranking
the engine. Af ter 5 or 6 seconds, stop
cranking by pushing the ignition switch to the LOCK position. Af ter
cranking the engine, release the ac-
celerator pedal. Crank the engine
with your foot off the accelerator
pedal by depressing the brake pedal
and pushing the ignition switch to
start the engine. If the engine starts,
but fails to run, repeat the above pro-
cedure.
CAUTION
Do not operate the starter for more
than 15 seconds at a time. If the engine
does not start, push the ignition switch
to the OFF position and wait 10 seconds
before cranking again, otherwise the
starter could be damaged.
4. Warm-up:
Allow the engine to idle for at least
30 seconds af ter starting. Do not race
the engine while warming it up. Drive at
a moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of 2 to 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.

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 re-
duced in snowy and icy conditions. If
you operate 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 driv-
ing 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 steering
maneuvers.
