cates heading direction of vehicle
cIndicates outside air temperature
With the ignition switch in the ON position, press
the
button as described in the chart below
to activate various features of the automatic anti-
glare review mirror.

For information about the automatic anti-glare
feature, refer to “Automatic anti-glare rearview
mirror” in the “Pre-driving checks and adjust-
ments” section.
OUTSIDE TEMPERATURE DISPLAY
Push thebutton for about 1 second when
the ignition key is in the ON position to toggle the
outside temperature and compass direction dis-
play
s1on or off.
cTo change from °F to °C, push and hold
the
button for about 3 seconds until
the display begins to flash. Press the button
again to toggle between °F and °C. Once
you have selected °F or °C, the display will
continue to flash for about 5 seconds, then
the temperature will display.cWhen the outside temperature is between
140°F (60°C) and 194°F (90°C) , the display
will read 140°F (60°C) . When the tempera-
ture is above 194°F (90°C) , the display will
read “SC”.
cWhen the outside temperature is between
-40°F (-40°C) and -60°F (-51°C) , the dis-
play will read -40°F (-40°C) . When the tem-
perature is below -60°F (-51°C) , the display
will read “OC”.
cThe outside temperature sensor is located in
front of the radiator. The sensor may be
affected by road or engine heat, wind direc-
tion and other driving conditions. The display
may differ from the actual outside tempera-
ture or the temperature displayed on various
signs or billboards.
cTemperature display will not update unless
the vehicle is moving faster than 12 MPH
(20 km/h) , or the ignition switch has been
OFF for 4 hours.

CAUTION
cDo not push start this vehicle. The
three-way catalyst may be damaged.
cAutomatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
cFor manual transmission models, never
try to start the vehicle by towing it.
When the engine starts, the forward
surge could cause the vehicle to collide
with the tow vehicle.
WARNING
cDo not continue to drive if your vehicle
overheats. Doing so could cause engine
damage or a vehicle fire.
cTo avoid the danger of being scalded,
never remove the radiator cap while the
engine is still hot. When the radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
cDo not open the hood if steam is com-
ing out.
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.
1. Move the vehicle safely off the road, apply
the parking brake and move the shift selector
to N (Neutral) (manual transmission) or to P
(Park) (automatic transmission) .
Do not stop the engine.
2. Turn off the air conditioner (if so equipped) .
Open all the windows, move the heater or air
conditioner temperature 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 radiator
before opening the hood. (If steam or cool-
ant is escaping, turn off the engine.) Do not
open the hood further until no steam or
coolant can be seen.
4. Open the engine hood.
WARNING
If steam or water is coming from the en-
gine, 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 radiator
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 en-
gine.
WARNING
Be careful not to allow your hands, hair,
jewelry or clothing to come into contact
with, or get caught in, engine belts or the
engine cooling fan. The engine cooling
fan can start at any time.
PUSH STARTING IF YOUR VEHICLE OVERHEATS
In case of emergency6-11

Steering wheelCheck for changes in the steer-
ing system, such as excessive freeplay, hard
steering or strange noises.
Warning lights and chimesMake sure all
warning lights and chimes are operating properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and that
the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly and in
sufficient quantity when operating the heater or
air conditioner.
Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery*Check the fluid level in each cell. It
should be between the MAX and MIN lines. Ve-
hicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*Make sure that
the brake and clutch fluid level is between the
MIN and MAX lines on the reservoir.
Engine coolant level*Check the coolant level
when the engine is cold.Engine drive belts*Make sure the drive belts
are not frayed, worn, cracked or oily.
Engine oil level*Check the level after parking
the vehicle on a level surface with the engine off.
Wait more than 10 minutes for the oil to drain
back into the oil pan.
Exhaust systemMake sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. See the
carbon monoxide warning in the “Starting and
driving” section of this manual.
Fluid leaksCheck under the vehicle for fuel, oil,
water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected imme-
diately.
Power steering fluid level* and linesCheck
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.Radiator and hosesCheck the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
UnderbodyThe underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances from the
underbody, otherwise rust may form on the floor
pan, frame, fuel lines and exhaust system. At the
end of winter, the underbody should be thor-
oughly flushed with plain water, in those areas
where mud and dirt may have accumulated. See
the “Appearance and care” section of this
manual.
Windshield washer fluid*Check that there is
adequate fluid in the reservoir.

The engine cooling system is filled at the factory
with Genuine NISSAN Long Life
Antifreeze/Coolant to provide year-round anti-
freeze and coolant protection. The anti-freeze
solution contains rust and corrosion inhibitors.
Additional engine cooling system additives are
not necessary.
WARNING
cNever remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. See precautions in “If your
vehicle overheats” found in the “In case
of emergency” section of this manual.
cThe radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a genuine
NISSAN radiator cap.
CAUTION
When adding or replacing coolant, be sure
to use only a Genuine NISSAN Long Life
Antifreeze/Coolant or equivalent with the
proper mixture ratio of 50% anti-freeze
and 50% demineralized or distilled water.
The use of other types of coolant solu-
tions other than a Genuine NISSAN Long
Life Antifreeze/Coolant or equivalent may
damage the engine cooling system.

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold.If the coolant level is below
the MIN level, add coolant to the MAX level. If the
reservoir is empty, check the coolant level in the
radiatorwhen the engine is cold.If there is
insufficient coolant in the radiator, fill the radiator
with coolant up to the filler opening and also add
it to the reservoir up to the MAX level.
The engine coolant reservoir is a pressur-
ized tank. When installing the cap, tighten
it until a clicking sound is heard.
