Important!
This vehicle is equipped with an air conditioning
system that uses R-134a (HFC: hydrofluorocarbon) as a
refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.

The system is always at operational readiness, except
when manually switched off.
The automatic climate control only operates with the
engine running.
The temperature selector should be left at the desired
temperature setting. The temperature selected is
reached as quickly as possible.
Th e system w il l not hea t or c ool a ny q uicker by setting a
higher or lower temperature.
The desired interior temperature and air distribution
can be selected separately for the left and right side of
the passenger compartment.
The automatic climate control removes considerable
moisture from the air during operation in the cooling
mode. It is normal for water to drip on the ground
through ducts in the underbody.
The air conditioning will not engage (no cooling) if the
economy modeS is selected, see page 173. Notes:
Do not obstruc t th e air f low by pl acing objec ts on th e a ir
flow-through exhaust slots below the rear window.
Also keep the air intake grill in front of the windshield
free of snow and debris.
The storage compartment between the front seats can be
ventilated. See page 175 for notes on ventilating the
storage space under the armrest in the center console.
The air conditioner switches itself off for its own
protection if refrigerant is lost. No cooling will then take

should this happen.
Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.

There are three basic settings for the automatic mode:
•Automatic air volume control
•Automatic air outlet control, left and right
•Automatic air outlet control, center, see page 165
We recommend these settings to be used all year round.Air volume and distribution are controlled
automatically.
Set the temperature switches on the left and right to
72°F (22°C). This provides for comfortable conditions in
the vehicle.
Automatic airf low regulation:
Press the A on the air volume switch. The display
shows “AUTO”.
Automatic air distribution:
Press on both Uknobs until they click in. Theh,
jand ksymbols will no longer be visible.
The economy mode and air recirculation functions will
be switched off. The automatic blower will be activated
at the same time.
