Vehicles with windshield heating also have a strip of
metal foil in the windshield and heating wires on the
contact surfaces of the windshield wipers. The
windshield can therefore be heated to prevent it
from frosting over and fogging up. Frozen windshield
wipers are thawed as quickly as possible.

b b High-voltage battery is sufficiently charged
(minimum 10 %).
b b Low fuel not yet reached.
The precooling/heating system regulates air flow, air
distribution and temperature. It can be set individu-
ally. The vehicle also regulates precooling/heating
intelligently according to the outside temperatures
to ensure the greatest possible comfort. This is the
case regardless of whether precooling/heating was
activated using a Pre-cool/heat timer, the vehicle
key or using the PCM function START PRE-COOL/
HEAT.
The precooling/heating system can be used to pre-
cool/heat the following (depending on equipment):
– the vehicle interior,
– the seats,
– the steering wheel,
– the door mirrors,
– the rear window,
– and the windshield,
without the combustion engine running. This is also
the case regardless of whether or not the vehicle
plug is connected.
