WARNING
∙ Operating the engine with the air

could be burned. Do not drive with the
air cleaner removed, and be careful
when working on the engine with the
air cleaner removed.
∙ Never pour fuel into the air intake sys- 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 aircleaner 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 re-
sult in engine damage.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information on change
intervals, refer to “Gasoline standard main-
tenance" or "Diesel standard mainte-
nance" in the "Maintenance and sched-
ules" section of the Titan Owner’s Manual.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.
