The engine and adjacent components, the exhaust
system and the coolant become very hot when the
engine is running.
The coolant reservoir is pressurized. The hot coolant
may suddenly escape if the coolant reservoir is not
opened carefully.
e Take care when working near hot vehicle parts,
particularly the engine and exhaust system.
e Always turn off the engine and allow it to cool
down before working in the engine
compartment.
e Always carry out work in the engine compart-
ment with the greatest care.
e Only top up coolant when the engine is stopped
and the ignition is switched off.

If you continue to operate the vehicle when a warn-
ing appears, you risk damaging the engine.

WARNING
coolant
NOTICE
The coolant provides year-round protection against
corrosion and freezing at temperatures as low as –
35 °F / –37 °C.
The coolant level is regularly checked as part of
servicing.
e Only use Porsche-approved freeze protection
agents.
Porsche recommends Glysantin G40 (alternatively:
freeze protection in accordance with G12++/VW TL
774 G) or Glysantin G65 (alternatively: freeze pro-
tection in accordance with G12evo/VW TL 774 LJ).
These freeze protection agents can be mixed.
Points to note about E-Hybrid
vehicles
E-Hybrid vehicles have a second cooling system
with an inaccessible coolant reservoir. The coolant
level does not need to be checked. Faults are dis-
played on the instrument cluster.
If a fault occurs in this second cooling system:
e Never attempt to add coolant.
e Visit an authorized Porsche dealer. Porsche rec-
ommends an authorized Porsche dealer, as they
have trained technicians and the necessary parts
and tools.
