2018 NISSAN FRONTIER Brake fluid

DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
anti-freeze, drain the cooling system, in-
cluding the engine block. Refill before oper-
ating the vehicle. For additional informa-
tion, 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.

When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions 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 ve-
hicle from moving. For manual trans-
mission models, move the shif t lever
to N (Neutral). For Automatic Trans-
mission (A/T) move the shif t lever to P
(Park)
∙ Be sure the ignition key 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 jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle. ∙ Always wear eye protection whenever
you work on your vehicle.
∙ 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, sup-
port 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
because the fuel lines are under high
pressure even when the engine is off.
It is recommended that you visit a
NISSAN dealer for this service.
CAUTION
∙ Do not work under the hood while theengine 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 the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
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, it is recommended
that you have it done by a NISSAN dealer.
