Operating tips
cKeep windows and sun roof closed while
the air conditioner is in operation.
cAfter parking in the sun, drive for two or
three minutes with the windows open to
vent hot air from the passenger compart-
ment. Then, close the windows. This
allows the air conditioner to cool the
interior more quickly.cThe air conditioning system should be
operated for about ten minutes at
least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
cIf 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 for additional in-
formation.
AIR FLOW CHARTS
The following charts show the button and
dial positions forMAXIMUM AND QUICK
heating, cooling or defrosting.The air recir-
culation switch should always be in the
OFF position for heating and defrosting.

Freeing a frozen door lock
To prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole.
If the lock becomes frozen, heat the key
before inserting it into the key hole.
Anti-freeze
In the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC),
check the anti-freeze (ethylene glycol base)
to assure proper winter protection. For de-
tails, see ``Engine cooling system'' in the
``Do-it-yourself operations'' section.
Battery
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For
details, see ``Battery'' in the ``Do-it-yourself
operations'' section.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by
opening the drain valves located under the
radiator and on the engine block. Refillbefore operating the vehicle. See ``Chang-
ing Engine Coolant'' in the ``Do-it-yourself
operations'' section.
Tire equipment
1. The SUMMER tires are of a tread design
to provide 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. Please consult your NIS-
SAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, stud-
ded tires may be used. However, some
provinces and states 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. Snow chains may be used if desired.
Make sure they are of proper size for the
tires on your vehicle and are installedaccording to the chain manufacturer's
suggestions.
Use of tire chains may be prohibited
according to location. Check the local
laws before installing tire chains. When
installing tire chains, make sure they are
of proper size for the tires on your vehicle
and are installed according to the chain
manufacturer's suggestions.Use only
SAE Class ªSº chains.Use chain ten-
sioners when recommended by the tire
chain manufacturer to ensure a tight fit.
Loose end links of the tire chain must be
secured or removed to prevent the pos-
sibility of whipping action damage to the
fenders or underbody. If possible, avoid
fully loading your vehicle when using tire
chains. In addition, drive at a reduced
speed, otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Never install tire chains on T-type and
small size spare tires. Do not use the
chains on dry roads.
Special winter equipment
It is recommended that the following items
be carried in the vehicle during winter:

Towing an automatic transmission
model with rear wheels raised (with
front wheels on the ground)
CAUTION
Never tow an automatic transmission
model with the rear wheels raised (with
the front wheels on the ground) as this
may cause serious and expensive dam-
age to the transmission. If it is neces-
sary to tow the vehicle with the rear
wheels raised, always use a towing
dolly under the front wheels.
If you have to tow an automatic
transmission model with four
wheels on ground
Observe the following restricted towing
speeds and distances.
cSpeed: Below 30 MPH (50 km/h)
cDistance: Less than 40 miles (65 km)
CAUTION
Never tow an automatic transmission
model from the rear (i.e., backward)
with four wheels on the ground as this
may cause serious and expensive dam-
age to the transmission.
VEHICLE RECOVERY (Freeing a
stuck vehicle)
cTow chains or cables must be attached
only to the main structual members of the
vehicle.
cPulling devices should be routed so they
do not touch any part of the suspension,
steering, brake or cooling systems.
cAlways pull the cable straight out from
the front or rear of the vehicle. Never pullon the vehicle at a sideways angle.
cPulling devices such as ropes or canvas
straps are not recommended for use in
vehicle towing or recovery.

When performing any inspection or mainte-
nance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
cPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the gearshift
control lever to Neutral (N).
cBe sure the ignition key is OFF when
performing any parts replacement or
repairs.
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cBe sure to turn the ignition key to the
OFF or LOCK position.
When the ignition key is in the ON or
ACC position, the cooling fan may
start to operate suddenly even when
the engine is not running.
cIf 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.cIt is advisable to remove ties and any
jewelry, such as rings, watches, etc.,
before working on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be
sure there is proper ventilation for
exhaust gases.
cNever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle, sup-
port it with safety stands.
cKeep smoking materials, flame and
sparks away from fuel and battery.
cNever connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition is
on.
cOn gasoline engine models with the
Multiport Fuel Injection (MFI) system,
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.
cFailure to follow these or other com-
mon sense guidelines may lead to
serious injury or vehicle damage.cImproperly disposed motor oil and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid. Avoid contact with used motor
oil.
This ``Do-it-yourself operations'' 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 your warranty coverage.If in
doubt about any servicing, have it done
by your NISSAN dealer.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze so-
lution contains rust and corrosion inhibitors,
therefore additional cooling system addi-
tives are not necessary.
CAUTION
When adding or replacing coolant, be
sure to use only an ethylene glycol
anti-freeze with the proper mixture ra-
tio. Examples are shown below:

The use of other types of coolant solu-
tions may damage your cooling system.
The radiator is equipped with a pressure
cap. Use a genuine NISSAN cap or its
equivalent when replacement is re-
quired.
Never remove the radiator cap when the
engine is hot. Serious burns could becaused by high pressure fluid escaping
from the radiator.
Wait until the engine and radiator cool
down. See precautions in ``If your ve-
hicle overheats'' found in the ``In Case Of
Emergency'' section.
CHECKING ENGINE COOLANT
LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level
is below MIN, add coolant up to the MAX
level. If the reservoir tank is empty, check
the coolant level in the radiatorwhen the
engine is cold.If there is insufficient cool-
ant in the radiator, fill the radiator with
coolant up to the filler opening and also add
it to the reservoir tank up to the MAX level.
