+Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+If skin disorders develop, obtain medical advice without delay.
+Where practicable, degrease components prior to handling.
+Where there is a risk of eye contact, eye protection should be
worn, for example, chemical goggles or face shields; in addi-
tion an eye wash facility should be provided.
Environmental Protection PrecautionsNJGI0001S0702Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt, check with the
appropriate local authority and/or manufacturer of the approved
appliance.
Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal sites, or to the
waste oil reclamation trade. If in doubt, contact the local authority
for advice on disposal facilities.
It is illegal to pour used oil on to the ground, down sewers or drains,
or into water courses.
The regulations concerning the pollution vary between
regions.
PRECAUTIONS FOR FUELNJGI0001S08Gasoline EngineNJGI0001S0803Europe
Models with three way catalyst
Unleaded premium gasoline of at least 95 octane (RON)
If premium gasoline is not available, unleaded regular gaso-
line with an octane rating of 91 (RON) may be temporarily
used, but only under the following precautions:
+Have the fuel tank filled only partially with unleaded regu-
lar gasoline, and fill up with premium unleaded gasoline
as soon as possible.
+Avoid full throttle driving and abrupt acceleration.
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Except For Europe
Models without three way catalyst
Leaded gasoline of at least 91 octane (RON)
Models with three way catalyst
Unleaded gasoline of above 91 octane (RON)
For improved vehicle performance, Nissan recommends the use of
premium unleaded gasoline above 95 octane (RON).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will dam-
age the three way catalyst.
Diesel Engine*:NJGI0001S0804Diesel fuel of at least 50 cetane
* If two types of diesel fuel are available, use summer or winter
fuel properly according to the following temperature conditions.
+Above þ7ÉC (20ÉF) ... Summer type diesel fuel.
+Below þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
+Do not use home heating oil, gasoline, or other alternate
