Climate control113Air conditioning system
In addition to the heating and
ventilation system, the air
conditioning system has controls for:
n=cooling4=air recirculation
Cooling n
Operated with the n button and is
functional only when the engine and
fan are running.
The air conditioning system cools and dehumidifies (dries) as soon as the
outside temperature is above a
specific level. Therefore
condensation may form and drip from
under the vehicle.
If no cooling or drying is required,
switch off the cooling system for fuel
saving reasons. Activated cooling
might inhibit Autostops.
Air recirculation system 4
Operated with the 4 button.9Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.

cooling is not possible when the
outside temperature is too low.
Service
For optimal cooling performance, it is
recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
■ Functionality and pressure test■ Heating functionality
■ Leakage check
■ Check of drive belts
■ Cleaning of condenser and evaporator drainage
■ Performance check
