tions on optimum use of the dual-zone or 3-zone
automatic climate control. R

Only use the "Windshield defrosting" function
briefly until the windshield is clear again. R
Only use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in
a tunnel. The windows could otherwise fog up,
since no fresh air is drawn into the vehicle in
air-recirculation mode. R

trol or PLUG-IN HYBRID: use the "residual
heat" function if you want to heat or ventilate
the vehicle interior when the ignition is
