Setting temperatureTo suit personal comfort, the interior temperature
for each of the four air-conditioned areas can be
adjusted between 61°F and 85°F (16°C and
29.5°C).
Recommendation: 72°F (22°C)
fPush temperature button up or down.
Button H:
Left air-conditioned area at the front or rear.
Button R:
Right air-conditioned area at the front or rear.
The selected temperature is shown on the
display above the button.
If “LO” or “HI” appears on the display, the system
is operating at maximum cooling or heating pow-
er.
If the preselected temperature is changed, the air
quantity blowing out can adjust automatically in au-
tomatic mode.
The desired temperature is reached more quickly
this way.

Information on air-conditioning
compressorThe air-conditioning compressor:
– Can switch off briefly if engine is under an ex-
treme load to ensure sufficient engine cooling.
– Switches off automatically at temperatures be-
low approx. 37.4°F (3°C) and cannot be
switched on, even manually.
– Operates most effectively with windows
closed.
If the car has been in the sun for a long time,
however, it is a good idea to ventilate the inte-
rior briefly with the windows open.
Notes on operation
Depending on the outside temperature and humid-
ity, condensation can drip from the evaporator
and form a pool under the car.
This is normal and not a sign of leakage.
If uncooled air flows out when the lowest temper-
ature has been set (“LO”), switch off the air-condi-
tioning compressor and have the fault remedied at
an authorized Porsche dealer.

Maintenance, Car Care Checking the coolant level when a warning
messages is shown on the multi-purpose
display of the instrument panel
Warning!
Danger of serious personal injury from scald-
ing. Coolant is hazardous to your health, and
may be fatal if swallowed.
fDo not open the cap of the expansion tank
while the engine is hot.
fAllow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
fKeep coolant out of children's reach.
fAlso, keep coolant away from your pets.They
can be attracted to it should there be a spill, or
to used coolant left in an open container. Cool-ant can be deadly to pets if consumed.1. Remove cover.
2. If the engine is hot, cover the the expansion
tank cap with a cloth.
Open cap carefully and allow any overpressure
to escape.
Then unscrew cap completely.
3. Read the coolant level.
Top up with coolant if necessary.
Only add a mixture of anti-freeze and water in
equal parts.
Antifreeze in coolant:
50% provides anti-freeze protection down to
-31°F (-35°C).
Do not exceed the max-mark.
Note on operation
fIf the coolant level exceeds the max-mark
when the engine is hot, check the coolant level
again when the engine is cold.
4. Screw the cap closed firmly and put on the
cover.
5. Have the cooling system checked by an author-
ized Porsche dealer.Maintenance note
If in an emergency pure water has been added, the
mixture ratio must be corrected at an authorized
Porsche dealer.
Marked loss of coolant indicates leakage in the
cooling system.
The cause should be remedied at an authoized
Porsche dealer immediately.
