compartment air may decrease
since the amount of outside
air entering the vehicle is reduced.
When the recirculation mode is
used without air conditioning, the
air humidity increases, and the
windows may fog. Avoid using the
recirculation mode during high
periods of humidity or cool outside
temperatures since this may result in
increased window fogging. If window
fogging is experienced, select the
defrost mode.

Notice:Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.
