GUID-AC78F4C5-074B-4FD0-8070-61F7D0EF17ACWhen 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.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely
and block the wheels to prevent
the vehicle from moving. For man-
ual transmission models, move the
shift lever to N (Neutral) . For auto-
matic transmission models, move
the selector lever to P (Park) .
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized com-
ponent while the ignition switch is
in the ON position.
. Never leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position. .
If you must work with the engine
running, 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
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work on your vehicle.
. 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 warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always disconnect the negative battery
cable before working near the fan.
. The fuel filter or fuel lines should be
serviced by a NISSAN dealer be-
cause the fuel lines are under high
pressure even when the engine is
off.
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 en-
gine oil and coolant. Improperly
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. Maintenance and do-it-yourself” section
gives instructions 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 Man-
ual order information” (P.9-25).)

the engine is running and after it reaches
normal operating temperature. If the coolant
level is below the MIN level
*2, add coolant up
to the MAX level
*1. If the reservoir is empty,
check the coolant level in the radiator when
the engine is cold. If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the radiator filler cap above the
radiator upper hose opening and also add it to
the reservoir up to the MAX level
*1. Put on the
filler cap above the radiator upper hose and with
the reservoir cap open, start the engine. Run the
engine until it reaches normal operating tem- perature. Add coolant up to the MAX level
*1.

All season tiresGUID-B2669784-76C5-43E8-8E16-E7F77F372F57NISSAN 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 tiresGUID-F3ED94EB-3952-42A0-831A-DC9822960777NISSAN 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 tiresGUID-4ABDD5F0-221F-4250-B31A-457D3FD59024If 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 CHAINSGUID-B7455203-4D74-496B-95E8-37BFF7A69A2B
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

LOADING TIPSGUID-C67193DE-BB8D-4966-AC31-739C2C3B1647.The GVW must not exceed GVWR or
GAWR as specified on the F.M.V.S.S./
C.M.V.S.S. certification label.
. Do not load the front and rear axle to
the GAWR. Doing so will exceed the
GVWR.
WARNING
.Properly secure all cargo to help
prevent it from sliding or shift-
ing. Do not place cargo higher
than the seatbacks. In a sudden
stop or collision, unsecured car-
go could cause personal injury.
. Do not load your vehicle any
heavier than the GVWR or the
maximum front and rear
GAWRs. If you do, parts of your
vehicle can break, tire damage
could occur, or it can change the
way your vehicle handles. This
could result in loss of control
and cause personal injury. .
Overloading could not only
shorten the life of your vehicle
and the tires, but also could lead
to hazardous vehicle handling
and long braking distance. This
may cause a premature tire
malfunction, which could result
in a serious accident and perso-
nal injury. Failures caused by
overloading are not covered by
the vehicle’s warranty.
MEASUREMENT OF WEIGHTSGUID-007BF927-7086-4838-9400-2E058EBA6F29Secure loose items to prevent weight shifts
that could affect the balance of your
vehicle. When the vehicle is loaded, drive
to a scale and weigh the front and the rear
wheels separately to determine axle loads.
Individual axle loads should not exceed
either of the gross axle weight ratings
(GAWR). The total of the axle loads should
not exceed the gross vehicle weight rating
(GVWR) . These ratings are given on the
vehicle certification label. If weight ratings
are exceeded, move or remove items to
bring all weights below the ratings.
