cooling NISSAN 370Z ROADSTER 2018 Owners Manual

WARNING
.The air conditioner cooling func-
tion operates only when the en-
gine is running.
. Do not leave children or adults
who would normally require the
support of others alone in your
vehicle. Pets should not be left
alone either. On hot, sunny days,
temperatures in a closed vehicle
could quickly become high en-
ough to cause severe or possibly
fatal injuries to people or animals.
. Do not use the recirculation mode
for long periods as it may cause
the interior air to become stale
and the windows to fog up.
Start the engine and operate the heater
and air conditioner system.
NOTE:
. Odors from inside and outside the
vehicle can build up in the air condi-
tioner unit. Odor can enter the pas-
senger compartment through the
vents.
. When parking, set the heater and air
conditioner controls to turn off air
recirculation to allow fresh air into the passenger compartment. This
should help reduce odors inside the
vehicle.

.Recirculating the cool air in thecabin when the A/C is on reduces
cooling load.
4. Drive at economical speeds and dis- tances.
.Observing the speed limit and notexceeding 60 MPH (97 km/h)
(where legally allowed) can improve
fuel efficiency due to reduced aero-
dynamic drag.
.Maintaining a safe following dis-tance behind other vehicles re-
duces unnecessary braking.
.Safely monitoring traffic to antici- pate changes in speed permits
reduced braking and smooth accel-
eration changes.
.Select a gear range suitable to roadconditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady
speed.
.Cruise control is particularly effec-tive in providing fuel savings when
driving on flat terrains.
6. Plan for the shortest route.
.Utilize a map or navigation system to determine the best route to save
time. 7. Avoid idling.
.Shutting off your engine when safe
for stops exceeding 30-60 seconds
saves fuel and reduces emissions.
8. Buy an automated pass for toll roads.
.Automated passes permit drivers to use special lanes to maintain cruis-
ing speed through the toll and
avoid stopping and starting.
9. Winter warm up.
.Limit idling time to minimize impact to fuel economy.
.Vehicles typically need no morethan 30 seconds of idling at start-
up to effectively circulate the en-
gine oil before driving.
.Your vehicle will reach its ideal
operating temperature more
quickly while driving versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade when-
ever possible.
.When entering a hot vehicle, open- ing the windows will help to reduce
the inside temperature faster, re-
sulting in reduced demand on your
A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire
wear and lowers fuel economy.
. Use the recommended viscosity en-
gine oil. (See “Engine oil and oil filter
recommendation” (P.10-7).)

INCREASING FUEL ECONOMY

FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing,
apply deicer through the key hole. If the
lock becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check antifreeze to assure
proper winter protection. For additional
information, see “Engine cooling system”
(P.8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery”
(P.8-11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced 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 you consult a
NISSAN dealer for the tire type, size, speed
rating and availability information.
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.
Tire chains may be used. For details, see
“Tire chains” (P.8-33) 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 win-
dows 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 window washer fluid to refill the
reservoir tank.
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.
. Whatever the condition, drive
with caution. Accelerate and slow
down with care. If accelerating or
downshifting too fast, the drive
wheels will lose even more trac-
Starting and driving5-33
COLD WEATHER DRIVING

To start your engine with a booster
battery, the instructions and precautions
below must be followed.
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. Bat-
tery fluid is a corrosive sulphuric
acid solution which can cause
severe burns. If the fluid should
come into contact with anything,
immediately flush the contacted
area with water.
. Keep the battery out of the reach
of children.
. The booster battery must be
rated at 12 volts. Use of an im-
properly rated battery can da-
mage 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 start-
ing.
. Do not attempt to jump start a
frozen battery. It could explode
and cause serious injury.
. Your vehicle has an automatic
engine cooling fan. It could come
on at any time. Keep hands and
other objects away from it.

2. Turn off the air conditioner. Open allthe windows, move the heater or air
conditioner temperature control to
maximum hot and fan control to high
speed.
3. If engine overheating is caused by climbing a long hill on a hot day, run
the engine at a fast idle (approxi-
mately 1,500 rpm) until the tempera-
ture 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.
(If steam or coolant is escaping, turn
off the engine.) Do not open the hood
further until no steam or coolant can
be seen.
5. Open the engine hood.
WARNING
If steam or water is coming from the
engine, stand clear to prevent get-
ting burned.
6. Visually check if the cooling fan is running. The radiator hoses and ra-
diator should not leak water. If coolant
is leaking or the cooling fan does not
run, stop the engine.
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.
7. After the engine cools down, check the coolant level in the reservoir with
the engine running. Add coolant to
the reservoir if necessary. Have your
vehicle repaired. It is recommended
you visit a NISSAN dealer for this
service.

8-2Do-it-yourself
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 following are general precau-
tions which should be closely observed.
WARNING
.Park the vehicle on a level sur-
face, apply the parking brake
securely and block the wheels to
prevent the vehicle from moving.
For manual transmission models,
move the shift lever to N (Neutral).
For automatic transmission mod-
els, move the shift lever to P
(Park).
. Be sure the ignition switch is in
the OFF or LOCK position when
performing any parts replace-
ment or repairs.
. Never connect or disconnect the
battery or any transistorized
component while the ignition
switch is in the ON position.
. Never leave the engine or auto-
matic transmission related com-
ponent harnesses disconnected
while the ignition switch is in the
ON position. .
If you must work with the engine
running, keep your hands, cloth-
ing, hair and tools away from
moving fans, belts and any other
moving parts.
. It is advisable to secure or re-
move any loose clothing and
remove any jewelry, such as
rings, watches, etc. before work-
ing on your vehicle.
. Always wear eye protection
whenever you work on your ve-
hicle.
. If you must run the engine in an
enclosed 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 necessary to work under the
vehicle, support it with safety
stands.
. Keep smoking materials, flame
and sparks away from fuel tank
and the battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It
may come on at any time without
warning, even if the ignition key is
in the OFF position and the en-
gine is not running. To avoid injury, always disconnect the ne-
gative battery cable before work-
ing near the fan.
. Because the fuel lines are under
high pressure even when the
engine is off, it is recommended
you visit a NISSAN dealer for
service of the fuel filter or fuel
lines.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used
engine oil and coolant. Impro-
perly disposed engine oil, coolant,
and/or other vehicle fluids can
damage the environment. Always
conform to local regulations for
disposal of vehicle fluid.
This “8. Do-it-yourself” section gives in-
structions regarding only those items
which are relatively easy for an owner to
perform.
A genuine NISSAN Service Manual is also
available. (See “Owner’s Manual/Service
Manual order information” (P.10-26).)
MAINTENANCE PRECAUTIONS

8-4Do-it-yourself
The engine cooling system is filled at the
factory with a pre-diluted mixture of 50%
Genuine NISSAN Long Life Antifreeze/
Coolant (blue) and 50% water to provide
year-round anti-freeze and coolant pro-
tection. The antifreeze solution contains
rust and corrosion inhibitors. Additional
engine cooling system additives are not
necessary.
WARNING
.Never remove the radiator or
coolant reservoir cap when the
engine is hot. Wait until the en-
gine and radiator cool down.
Serious burns could be caused
by high pressure fluid escaping
from the radiator. See precau-
tions in “If your vehicle overheats”
(P.6-17) of this manual.
. The radiator is equipped with a
pressure type radiator cap. To
prevent engine damage, use only
a genuine NISSAN radiator cap.
CAUTION
.Never use any cooling system
additives such as radiator sealer.
Additives may clog the cooling
system and cause damage to
the engine, transmission and/or
cooling system.
. When adding or replacing cool-
ant, be sure to use only Genuine
NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent. Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) is pre-diluted to
provide antifreeze protection to
−34°F (−37°C). If additional freeze
protection is needed due to
weather where you operate your
vehicle, add Genuine NISSAN Long
Life Antifreeze/Coolant (blue)
concentrate following the direc-
tions on the container. If an
equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain mini-
mum antifreeze protection to
−34°F (−37°C). The use of other
types of coolant solutions other
than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent may damage the en-
gine cooling system.
. The life expectancy of the fac-
tory-fill coolant is 105,000 miles
(168,000 km) or 7 years. Mixing
any other type of coolant other
than Genuine NISSAN Long Life
Antifreeze/Coolant (blue), includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green), or
the use of non-distilled water will
reduce the life expectancy of the
factory-fill coolant. Refer to the
“9. Maintenance and schedules”
section of this manual for more
details.
