9-6Technical and consumer information
knock even when using gasoline of the
stated octane rating, or if you hear steady
spark knock while holding a steady speed
on level roads, have an INFINITI retailer
correct the condition. Failure to correct the
condition is misuse of the vehicle, for
which INFINITI is not responsible.
Incorrect ignition timing will result in
knocking, after-run or overheating. This in
turn may cause excessive fuel consumption
or damage to the engine. If any of the
above symptoms are encountered, have
your vehicle checked at an INFINITI retailer
or other competent service facility.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

CAUTION
The use of any other refrigerant or lubricant
will cause severe damage to the air con-
ditioning system and will require the repla-
cement of all air conditioner system
components.
The refrigerant HFC-134a (R-134a) in your
INFINITI vehicle will not harm the earth’s
ozone layer. Although this refrigerant does
not affect the earth’s atmosphere, certain
governmental regulations require the re-
covery and recycling of any refrigerant
during automotive air conditioning system
service. Your INFINITI retailer has the
trained technicians and equipment needed
to recover and recycle your air conditioning
system refrigerant.
Contact an INFINITI retailer when servicing
your air conditioning system.
