A- Front carrier, long
B -Rear carrier, short
C -Cover trims
D - Torque wrench
E - Roof channel protectors
F -KeyFitting the roof transport systemWhen fitting the roof transport system for the first
time, the front and rear carrier must be adjusted
according to the width of the vehicle.
Roof channel protectors can also be secured to
the vehicle when fitting the roof transport system
for the first time. These protectors make it easier
to fit the roof transport system and protect the
fastening recesses in the roof rails from damage. 1. Open the cover flap on the roof rails.
2. Unscrew plastic screws from the retaining
threads.
f Make sure not to lose the plastic screws.
Note
When you have removed the roof transport
system, the plastic screws can be screwed back
into the retaining threads to prevent dirt from
getting into the threads. 3. Position the long carrier
A at the front and
the short carrier B at the rear loosely on the
fastening recesses.
f Fastening screws on the carriers must not
protrude underneath as this would damage
the vehicle.
f Make sure that the carriers are aligned in
accordance with the specifications on the
stickers on the underside of the carriers.

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.

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.

Changing a wheel
Danger!
Failure to follow these instructions may result
in serious personal inju ry or death to you or
to bystanders.
Before changing the wheel
f If you have a flat tire, move a safe distance off
the road. Turn the emergency flasher on and
use other warning devices to alert other
motorists.
f Do not park your vehicl e where it may contact
dry grass, brush or other flammable materials.
The hot parts of the exhaust system could set
such materials on fire, thereby causing both
property damage and severe or fatal physical
injury.
f Passengers must not be in the vehicle when it
is jacked up.
f Before you change a wheel, be sure the ground
is level and firm. If necessary, use a board
under the jack to ensure that the jack does not
sink into the ground.
f Set the electric parking brake and block the
wheels opposite the flat tire on the other side
of the vehicle.
While operating the jack
f The jack is only to be used for changing a
wheel. Do not use it as a support to work under
the car. f
The car must be jacked up only at the
illustrated jacking points. Lifting at any other
place may damage the vehicle or may result in
personal injury. Never jack the car up by the
body or the bumpers.
f For safety reasons do not use tire inflating
bottles. Do not use co mmercially available
sealant bottles. Use only the tire inflating bottle
located in the luggage compartment.
Note
The tools required for changing a wheel (e.g. jack,
wheel bolt wrench, assembly aids) are not
supplied as standard with the vehicle. Your
authorized Porsche dealer will be pleased to
advise you.
