6-10In case of emergency
position, then screw the hose securely
onto the tire valve. Check the tire
pressure with the pressure gauge. The
temporary repair is completed if the tire
pressure does not drop.
Make sure the pressure is adjusted to the
pressure that is specified on the tire and
loading information label before driving.
10. If the tire pressure drops, repeat the
steps from 5 to 9. If the pressure drops
again or under 19 psi (130 kPa),the tire
cannot be repaired with this tire punc-
ture repair kit.It is recommended you
visit an INFINITI retailer for this servi-
cing.
The sealant bottle and hose cannot be
reused to repair another punctured tire.
It is recommended you visit an INFINITI
retailer to purchase replacements.
After repairing tire
It is recommended you visit an INFINITI
retailer for tire repair/replacement as soon
as possible.
WARNING
.After using Emergency Tire Sealant
to repair a minor tire puncture, do not
drive the vehicle at speeds fasterthan 50 MPH (80 km/h).
.Immediately after using Emergency
Tire Sealant to repair a minor tire
puncture, take your vehicle to in-
spect, and repair or replace the tire.
It is recommended you visit an
INFINITI retailer for this service. The
Emergency Tire Sealant cannot per-
manently seal a punctured tire. Con-
tinuing operation of the vehicle
without a permanent tire repair can
lead to a crash.
.INFINITI recommends using only
Genuine NISSAN Emergency Tire
Sealant provided with your vehicle.
Other tire sealants may damage the
valve stem seal which can cause the
tire to lose air pressure. It is recom-
mended you visit an INFINITI retailer
as soon as possible after using tire
repair sealant.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. Battery fluid is a
corrosive sulphuric acid solution
which can cause severe burns. If the
fluid should come into contact with
anything, immediately flush the con-
tacted area with water.
.Keep the battery out of the reach of
children.
.The booster battery must be rated at
12 volts. Use of an improperly rated
battery can damage your vehicle.

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 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 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 compo-
nent while the ignition switch is in the
ON position.
.Never leave the engine or automatic
transmission related component har-
nesses disconnected while the igni-
tion 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 movingparts.
.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 dis-
connect the negative battery cable
before working near the fan.
.Because the fuel lines are under high
pressure even when the engine is off,
it is recommended you visit an
INFINITI retailer for service of thefuel filter or fuel lines.
