socket it is still possible in a warm climate to
achieve brief cooling of the passenger com-
partment by direct starting preconditioning.
NOTE
The vehicle doors and windows should be
closed during preconditioning of the passen-
ger compartment.

The climate in the passenger compartment can
be maintained when the vehicle is parked, e.g. if
the engine is turned off but the driver or passen-
gers remain in the vehicle. This function can only be direct-started.
The function utilizes several of the vehicle's sys-
tems:
• Residual heat from the engine is used to
help heat the passenger compartment to a
comfortable temperature.
• In warm weather, the ventilation system cools
the passenger compartment by blowing air in
from outside.
NOTE Climate comfort maintenance will be deacti-
vated if the vehicle is locked from the outside
in order to avoid using residual engine heat
unnecessarily. This function is intended to be
used to maintain climate comfort when the
driver or a passenger remains in the vehicle
after the engine is turned off.
