Checking Coolant Level and
Adding CoolantThe coolant provides year-round protection
from corrosion and freezing down to –31 °F
(–35 °C) (–40 °F (–40 °C) in Nordic countries).
Observe the following points:
fUse only antifreeze authorised by Porsche.
f Check the coolant level regularly.Coolant levelWhen the engine is cold and the vehicle is level,
the red display must be under the arrow between
the minus and plus markings.
f Add coolant if necessary.
The maximum fill level is reached when the red
display is under the plus marking.
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 152.
f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on page 252. Checking when engine is cold
1. Open cap on the reservoir carefully and
allow any overpressure to escape.
Then unscrew cap completely.
2. Read off the engine coolant level.
3. Top up with coolant if necessary. Do not top up over the plus marking.
Only add a mixture of antifreeze and water
in equal parts.
Antifreeze in coolant:
50 % provides antifreeze protection
down to –31 °F (–35 °C).
4. Screw the cap on the reservoir closed until it locks securely. Checking the coolant level when a warning
message appears on the multi-function
display in the instrument panel
Warning!
Danger of serious personal injury or death
from scalding. Coolant is hazardous to your
health, and may be fatal if swallowed.
f Do not open the cap of the expansion tank
while the engine is hot.
f Allow the engine to cool down before opening
the cap and protect your hands, arms and face
from any possible escape of hot coolant.
f Keep coolant out of children's reach.
f Also, 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. Coolant can be deadly to pets if consumed.

Maintenance and Car Care
1. If the engine is hot, cover the reservoir cap
with a cloth.
Open cap carefully and allow any overpressure
to escape.
Then unscrew cap completely.
2. Read off the engine coolant level. Top up with coolant if necessary.
Only add a mixture of antifreeze and water
in equal parts.
Antifreeze in coolant:
50 % provides antifreeze protection
down to –31 °F (–35 °C).
Do not top up over the plus marking.
3. Screw the cap on the reservoir closed until it locks securely.
4. Have the cooling system checked. Please contact a qualif ied specialist workshop.
We recommend that you have an authorized
Porsche dealer to do this work as they have
trained workshop personnel and the necessary
parts and tools. Maintenance notes
If pure water is added in an emergency, the mixing
ratio will have to be corrected.
A significant loss of coolan
t indicates a leak in the
cooling system.
f The cause must be eliminated without delay.
Please contact a qualified specialist workshop.

Radiator fansThe radiators and radiator fans are in the front
of the vehicle.
Warning!
Risk of injury.
The fans can start running when a certain
temperature is reached, even with the
engine switched off.
f Exercise extreme care when working close to
the radiator fans and make sure the engine is switched off.
Brake FluidRegular checking of the brake fluid is part of
servicing.
The fluid level should always be between the
MIN and MAX markings.
A slight decrease in the fluid level due to wear
and automatic readjustment of the disc brakes
is normal.
However, if the fluid level falls significantly or
goes below the MIN marking, the brake system
may have developed a leak.
fHave the brake system checked immediately.
Please contact a qualified specialist workshop.
