been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected
immediately.
Power steering fluid level* and lines:Check
the level when the fluid is cold, with the engine
off. Check the lines for proper attachment, leaks,
cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections.
Underbody: The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the end
of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. (
“UNDERBODY” page 7-3)
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.
When 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. Move the
shift lever to the
&Pposition.
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. 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.

If the low tire pressure and the run-flat tire
warning appears on the vehicle information
display:
.Do not exceed 50 MPH (80 km/h) .
. Increase your following distance to allow for
increased stopping distances.
. Avoid sudden maneuvers, hard cornering
and hard braking.
WARNING
.Although you can continue driving
with a punctured run-flat tire, re-
member that vehicle handling sta-
bility is reduced, which could lead to
an accident and personal injury.
Also, driving a long distance at high
speeds may damage the tire.
. Do not drive at speeds above 50
MPH (80 km/h) and do not drive
more than 50 miles (80 km) with a
punctured run-flat tire. The actual
distance the vehicle can be driven
on a flat tire depends on outside
temperature, vehicle load, road con-
ditions and other factors.
. Drive safely at reduced speeds. Avoid hard cornering or braking,
which may cause you to lose control
of the vehicle.
NOTICE
.
Never install tire chains on a punc-
tured run-flat tire, as this could
damage your vehicle.
. Avoid driving over any projection or
pothole, as the clearance between
the vehicle and the ground is smal-
ler than normal.
. Do not enter an automated car wash
with a punctured run-flat tire.
. Have the punctured tire replaced by
a GT-R certified NISSAN dealer as
soon as possible, as the tire’s
performance capability is reduced.Tires for All-Wheel Drive (AWD)If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the specified size, brand, construction and
tread pattern. The tire pressure and wheel
alignment should also be checked and cor-
rected as necessary. Contact a GT-R certified
NISSAN dealer.
TIRE CHAINSUse 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 of proper size for the tires on your
vehicle and are installed according to the chain
manufacturer instructions. 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 recommended 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 undercarriage.
If possible, avoid fully loading your vehicle when
using tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be da-
maged and/or vehicle handling and performance
may be adversely affected.NOTE:Tire chains must be installed only on the
rear wheels and not on the front wheels.

.Do not use abrasive cleaners when washing
the wheels.
. Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
. NISSAN recommends that the side walls of
road wheels be waxed to protect against
road salt in areas where it is used during
winter.JACKING VEHICLE AND REMOVING
WHEELS
WARNING
.Make sure the parking brake is
securely applied and the transmis-
sion is shifted into the

Do not use oil or grease on the
wheel studs or nuts. This could
cause the nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) .
WARNING
If the road wheels are hot, allow them
to cool sufficiently before tightening
the wheel nuts. Otherwise, the wheel
nuts cannot be tightened to specifica-
tion.NOTE:.As soon as possible, tighten the wheel
nuts to the specified torque with a

amount of cargo and luggage load
capacity. For example, if the XXX
amount equals 1400 lbs. and there will
be five 150 lb. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs.
(1400750 (5 x 150) = 650 lbs) or
640 340 (5 x 70) = 300 kg.)
5.
Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
6.
If your vehicle will be towing a trailer,
load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail-
able cargo and luggage load capacity
of your vehicle.
Before driving a loaded vehicle, confirm
that you do not exceed the Gross Vehicle
Weight Rating (GVWR) or the Gross Axle
Weight Rating (GAWR) for your vehicle.
(“MEASUREMENT OF WEIGHTS” page
9-13)
Also check tires for proper inflation pres-
sures. See the Tire and Loading Information label.
LOADING TIPS.
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 vehicleand 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. Repairs due to over-
loading the vehicle are not
covered by the vehicle’s war-
ranty. (See the 2009 NISSAN
GT-R Warranty Information
Booklet.)
MEASUREMENT OF WEIGHTSSecure 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.Technical and consumer information
