than 36°F (2°C) . If in defrost mode for more
than one minute, the air conditioning system
will continue to operate until the fan control
dial is turned to OFF, the vehicle is shut off, or
the A/C button is used to turn off the com-
pressor even if the air flow control dial is
turned to a position other than the
po-
sition. This dehumidifies the air which helps
defog the windshield. The
mode auto-
matically turns off, allowing outside air to be

Operating tips
●Keep the windows closed while the air con-
ditioner is in operation.
● After parking in the sun, drive for 2 or 3
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
Heater, air conditioner, audio and phone systems4-13

●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. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

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 inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing 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 details see
“Tire chains” in the “Maintenance and 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 remove
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 snowdrifts.
● 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” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.
COLD WEATHER DRIVING
5-38Starting and driving

To start your engine with a booster battery, the
instructions and precautions below must be fol-
lowed.
WARNING
●If done incorrectly, jump starting can
lead to a battery explosion, resulting in
severe injury or death. It could also
damage your vehicle.
● Explosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
the battery.
● Do not allow battery fluid to come into
contact with eyes, skin, clothing or
painted surfaces. Battery fluid is a cor-
rosive sulfuric acid solution which can
cause severe burns. If the fluid should
come into contact with anything, imme-
diately flush the contacted area with
water.
● Keep battery out of the reach of
children.
● The booster battery must be rated at 12
volts. Use of an improperly rated battery
can damage your vehicle. ●
Whenever working on or near a battery,
always wear suitable eye protectors (for
example, goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other jewelry. Do not lean
over the battery when jump starting.
● Do not attempt to jump start a frozen
battery. It could explode and cause se-
rious injury.
● Your vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
JUMP STARTING
In case of emergency6-9

CAUTION
●Do not push start this vehicle. The
three-way catalyst may be damaged.
● Automatic transmission models cannot
be push-started or tow-started. At-
tempting to do so may cause transmis-
sion damage.
● For 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
● Do not continue to drive if your vehicle
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 radiator
cap is removed, pressurized hot water
will spurt out, possibly causing serious
injury.
● Do 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.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
●Park the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift selector to
P (Park) .
● Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
● If you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
● It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
● Always wear eye protection whenever
you work on your vehicle. ●
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come
on at any time without warning, even if
the ignition switch is in the OFF posi-
tion and the engine is not running. To
avoid injury, always disconnect the
negative battery cable before working
near the fan.
● If you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
● Never get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
● Keep smoking materials, flame and
sparks away from the fuel tank and
battery.
● On gasoline engine models, the fuel
filter or fuel lines should be serviced by
a NISSAN dealer because the fuel lines
are under high pressure even when the
engine is off.
CAUTION
● Do not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
● Avoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
● Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
● Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
This “Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
You should be aware that incomplete or improper
servicing may result in operating difficulties or
excessive emissions, and could affect warranty
coverage. If in doubt about any servicing,
have it done by a NISSAN dealer.
