winter tires NISSAN 370Z ROADSTER 2016 Z34 Owners Manual

5-24Starting and driving
.Recirculating the cool air in the cabinwhen the A/C is on reduces cooling load.
4. Drive at economical speeds and distances.
.Observing the speed limit and not ex- ceeding 60 MPH (97 km/h) (where
legally allowed) can improve fuel effi-
ciency due to reduced aerodynamic
drag.
.Maintaining a safe following distancebehind other vehicles reduces unneces-
sary braking.
.Safely monitoring traffic to anticipatechanges in speed permits reduced brak-
ing and smooth acceleration changes.
.Select a gear range suitable to road conditions.
5. Use cruise control.
.Using cruise control during highway driving helps maintain a steady speed.
.Cruise control is particularly effective 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 cruising 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 more than 30seconds of idling at start-up to effectively
circulate the engine oil before driving.
.Your vehicle will reach its ideal operatingtemperature more quickly while driving
versus idling.
10. Keeping your vehicle cool.
.Park your vehicle in a covered parking area or in the shade whenever possible.
.When entering a hot vehicle, opening thewindows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system. .
Keep your engine tuned up.
. Follow the recommended scheduled main-
tenance.
. 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 engine oil.
(See “Engine oil and oil filter recommenda-
tion” (P.9-6) .)

operate properly and the VDC warn-
ing lightmay illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.

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 328F(08C) ,
check antifreeze to assure proper winter protec-
tion. For additional information, see “Engine
cooling system” (P.8-8).
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.8-15) .
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “Engine cooling system”
(P.8-8) .
TIRE EQUIPMENT
SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. 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.
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.8-36) 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 window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
.Wet ice (328F, 0 8C 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 down-
shifting 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 pave-
ment.
. Allow greater following distances
on slippery roads.
COLD WEATHER DRIVING

8-36Maintenance and do-it-yourself
All season tires
NISSAN specifies all season tires on some
models to provide good performance all year,
including snowy and icy road conditions. All
Season tires are identified by ALL SEASON
and/or M&S (Mud and Snow) on the tire
sidewall. Snow tires have better snow traction
than All Season tires and may be more appro-
priate in some areas.
Summer tires
NISSAN specifies summer tires on some
models to provide superior performance on dry
roads. Summer tire performance is substantially
reduced in snow and ice. Summer tires do not
have the tire traction rating M&S on the tire
sidewall.
If you plan to operate your vehicle in snowy or
icy conditions, NISSAN recommends the use of
SNOW tires or ALL SEASON tires on all four
wheels.
Snow tires
If snow tires are needed, it is necessary to select
tires equivalent in size and load rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires will have lower speed
ratings than factory equipped tires and may notmatch the potential maximum vehicle speed.
Never exceed the maximum speed rating of the
tire.
If you install snow tires, they must be the same
brand, construction and tread pattern on all four
wheels, and the same sizes as the original tires.
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 cap-
abilities of studded snow tires, on wet or dry
surfaces, may be poorer than that of non-
studded snow tires.
TIRE CHAINS
CAUTION
Tire chains/cables should not be in-
stalled on 19-inch size tires. Doing so
will cause damage to the vehicle. If you
plan to use tire chains/cables, you
should install 18-inch size tires on your
vehicle.
Use of tire chains may be prohibited according
to location. Check the local laws before instal-
ling tire chains. When installing tire chains, make sure they are the proper size for the tires on your
vehicle and are installed according to the chain
manufacturer’s suggestions.
Use only SAE
Class S chains. Class “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are
designed to meet the SAE standard minimum
clearances between the tire and the closest
vehicle suspension or body component required
to accommodate the use of a winter traction
device (tire chains or cables) . The minimum
clearances are determined using the factory
equipped tire size. Other types may damage
your vehicle. Use chain tensioners when re-
commended 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 possibility 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.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Never install tire chains on a TEMPORARY USE
ONLY spare tire.
Do not use tire chains on dry roads. Driving with
