tem or attempt to start the engine with
the air cleaner removed. Doing so could
result in serious injury.
● Do not use starting fluids with this en-
gine. The use of starting fluid could
cause an explosion, fire, personal in-
jury, system or engine damage.
CAUTION
● Operating the engine with the air
cleaner removed can cause damage to
the turbocharger and major engine
damage.
● Never pour fuel into the intake or at-
tempt to start the engine with the air
cleaner removed. Doing so could result
in engine damage.
IN-CABIN MICROFILTER

borne dust and pollen particles and reduces
some objectionable outside odors. The filter is
located behind the glove box. For additional in-
formation on change intervals, refer to “Gasoline

ules section of this manual.
If replacement is required, it is recommended that
you visit a NISSAN dealer for this service.
