Air vents

G Warning!

When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold (depending on the set temperature).
This may cause burns or frostbite to
unprotected skin in the immediate area of
the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in
the vehicle interior that are not in the
immediate area of unprotected skin.

For best possible performance of the climate
control:

X

Keep the air intake grille in front of the
windshield free of snow, leaves, sticks, and
any other debris.

X

Always keep all air vents and grilles in the
passenger compartment free from
obstruction.
