Adjusting the AIRSCARF vents
& WARNING Risk of burns caused by the
heating output from AIRSCARF being too
high
When AIRSCARF is switched on, very hot air
can flow from the outlet opening in the head
restraints.
This could result in burns in the immediate
vicinity of the outlet opening.
Turn the heating output down in good
#
time.
Maintain a suitable distance from the
#
outlet opening.
* NOTE Damage caused to AIRSCARF by
the use of protective covers
If a protective cover is placed over the front
seat head restraints, the flow of air from the
AIRSCARF vent is hindered.
This can cause AIRSCARF to overheat and be
damaged.
Do not use protective covers on head
#
restraints with AIRSCARF.
Make sure that there are no objects covering the
intake grille on the back of the head restraint.
You can adjust the blower output of AIR‐
#
SCARF vents 1 using the AIRSCARF button
( page 101).
/
You can adjust the height of AIRSCARF vents
#
1 and the current of air by adjusting the
height of the head restraint (
/
page 96).
