1997 NISSAN PATHFINDER cooling

brake system will then behave normally, but
without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your
vehicle to your NISSAN dealer for repair at
your earliest convenience.
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. Stopping distances may also be
longer on rough, gravel or snow covered
roads, or if you are using tire chains.
Always maintain a safe distance from
the vehicle in front of you. Ultimately,
the responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition may also affect
braking effectiveness.IWhen replacing tires, install the
specified size of tires on all 4 wheels.
Refer to ªWheels and tiresº in the
ªDo-it-yourself operationsº section.
IWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. For tire
placard location information, refer to
ªTire placardº in the Owner's Manual
index.
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
anti-freeze (ethylene glycol base) to assure
proper winter protection. For details, see ªEn-
gine Cooling Systemº in the ªDo-it-yourself
operationsº section.
Battery
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
ªBatteryº in the ªDo-it-yourself operationsº sec-
tion.
Draining of coolant water
If the vehicle is to be left outside without
anti-freeze, drain the cooling system by open-
ing the drain valves located under the radiator
and on the engine block. Refill before operat-
ing the vehicle. For details, see ªChanging

5. Securely store the spare tire and jacking
equipment in the vehicle.
Always make sure that the spare tire and
jacking equipment are properly secured
after use. Such items can become dan-
gerous projectiles in an accident or sud-
den stop.
If you try to start your engine with a booster
battery, follow the instructions and precautions
below:
IIf done incorrectly, jump starting can
lead to a battery explosion, resulting
in severe injury or death. It could also
damage your vehicle.
IExplosive hydrogen gas is always
present in the vicinity of the battery.
Keep all sparks and flames away from
it.
IDo not allow battery fluid to come
into contact with eyes, skin, cloth or
painted surfaces. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
IKeep battery out of the reach of chil-
dren.
IThe booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.IWhenever working on or near a bat-
tery, always wear suitable eye protec-
tors (e.g., goggles or industrial safety
spectacles) and remove rings, metal
bands, or any other metal jewelry. Do
not lean over battery when jump-
starting.
IDo not attempt to jump start a frozen
battery. It could explode and cause
serious injury.
IYour vehicle has an automatic engine
cooling fan. It could come on at any
time. Keep hands and other objects
away from it.
JUMP STARTING

IAutomatic transmission models can-
not be started by pushing. This may
cause transmission damage.
IThree-way catalyst equipped models
should not be started by pushing
since the three-way catalyst may be
damaged.
INever try to start the vehicle by tow-
ing 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:
IDo not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
ITo avoid the danger of being burned,
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.
IDo not open the hood if steam is
coming out.
1. Move the vehicle safely off the road, apply
the parking brake and move the gearshift
lever to the neutral position (automatic
transmission to ªPº).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi-
tioner temperature control to ªmaximumhotº and fan control to ªhigh speedº.
3. If engine overheating is caused by climbing
a long hill on a hot day, run the engine at a
fast idle (approximately 1,500 rpm) until the
temperature gauge indication returns to
normal.
4. Get out of the vehicle. Look and listen for
steam or coolant escaping from the radiator
before opening the hood. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. 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 cooling fan belt is missing or loose or
the cooling fan does not run, stop the
engine.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.
When adding or replacing the coolant,
be sure to use an ethylene glycol anti-
freeze with the proper mixture ratio of
50% anti freeze and 50% distilled water.
The use of other types of coolant solu-
tions may damage your engine cooling
system.

IThe radiator is equipped with a pres-
sure cap. Use a NISSAN genuine cap
or its equivalent when replacement is
required.
CHECKING COOLANT LEVEL
With coolant reservoir
Check the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the ªMINº level, add coolant to the
ªMAXº level. If the reservoir tank 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 tank up to the ªMAXº level.
