2003 INFINITI G35 warning

WARNINGO Do not continue to drive if your ve-
hicle overheats. Doing so could
cause a vehicle fire.
O To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the radia-
tor cap is removed, pressurized hot
water will spurt out, possibly causing
serious injury.
O Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading), or
if you feel a lack of engine power, detect
abnormal noise, etc., take the following steps:
1. Move the vehicle safely off the road, apply
the parking brake and move the shift lever
to the N (Neutral) position (automatic trans-
mission to the P (Park) position).
Do not stop the engine.
2. Turn off the air conditioner switch. Open all
the windows, move the heater or air condi- tioner 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 (approximately 1,500 rpm) until the
temperature 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. Wait until no
steam or coolant can be seen before pro-
ceeding.
5. Open the engine hood.
WARNING If steam or water is coming from the
engine, stand clear to prevent getting
burned.
6. Visually check if the cooling fan is running.
The radiator hoses and radiator should not
leak water.
If coolant is leaking or the cooling fan does
not run, stop the engine. WARNING O Be careful not to allow your hands,
hair, jewelry or clothing to come into
contact with, or to get caught in the
cooling fan, or drive belt.
O The engine cooling fan can start at
any time when the coolant tempera-
ture is high.
7. After the engine cools down, check the
coolant level in the reservoir tank with the
engine running. Add coolant to the reservoir
tank if necessary. Have your vehicle re-
paired at the nearest INFINITI retailer.

FLOOR MATS The use of Genuine INFINITI floor mats can
extend the life of your vehicle carpet and make
it easier to clean the interior. No matter what
mats are used, be sure they are fitted for
your vehicle and are properly positioned in
the footwell to prevent interference with
pedal operation. Mats should be maintained
with regular cleaning and replaced if they
become excessively worn.
Floor mat positioning aid
(Driver side only) This model includes a front floor mat bracket to
act as a floor mat positioning aid. INFINITI
floor mats have been specially designed for
your vehicle model. The driver's side floor mat
has a grommet hole incorporated in it. Simply
position the mat by placing the floor mat
bracket through the floor mat grommet hole
while centering the mat in the floorpan contour.
Periodically check to make certain that the
mats are properly positioned. SEAT BELTS The seat belts can be cleaned by wiping them
with a sponge dampened in a mild soap solu-
tion. Allow the belts to dry completely before
using them.
WARNING Do not allow wet belts to roll up in the
retractor. NEVER use bleach, dye, or
chemical solvents since these may se-
verely weaken the seat belt webbing. SAI0012

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.
WARNINGO Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an automatic
transmission, move the selector lever
to P (Park) position.
O Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
O 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.
O It is advised to secure or remove any loose clothing and any jewelry, such
as rings, watches, etc. before work-
ing on your vehicle.
O Always wear eye protection when-
ever you work on your vehicle.
O 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.
O Never get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
O Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.
O On gasoline engine models with the
Multiport Fuel Injection (MFI) System,
the fuel filter or fuel lines should be
serviced by an INFINITI retailer be-
cause the fuel lines are under high
pressure even when the engine is off. CAUTION O Do not work under the hood while the
engine is hot. Turn off the engine and
wait until it cools down.
O Never connect or disconnect either
the battery or any transistorized com-
ponent connector while the ignition
key is on.
O Never leave any engine or automatic
transmission related component har-
ness connector disconnected while
the ignition key is on.
O Avoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.

The engine cooling system is filled at the
factory with a high-quality, year-round, anti-
freeze coolant solution. The anti-freeze solu-
tion contains rust and corrosion inhibitors,
therefore additional cooling system additives
are not necessary.

sure to use only a genuine NISSAN anti-
freeze coolant or equivalent with the
proper mixture ratio of 50% anti-freeze
and 50% demineralized water/distilled
water. The use of other types of coolant
solutions may damage your engine
cooling system. Outside temperature
