TIONS” on Page 213.
Warning!
When opening or closing the convertible top,
serious personal injury may occur if a per-
son’s body parts are near or in the way of the
convertible top mechanism’s moving parts.
f Make absolutely sure that nobody can be
injured by the convertible-top mechanism or the convertible-top compartment lid.
Do not operate convertible top:
– At temperatures below 32 °F/0 °C.
– When one side of the ca r is on a curb, a hoist
or a jack.
– When items of luggage or other objects hinder the convertible top movement.
f Drive only with the convertible top fully open or
closed (end positions). f
Items of luggage or objects on the luggage
tray above the engine compartment lid must
be put in the storage box or be secured to
prevent their sliding out. These items must not
be in abrasive contact with the convertible top
or rear window. Keep s hutters of the storage
box closed while driving.

convertible top (e.g. in the garage).
f To prevent damp stains and abrasions, only
open the convertible top in a dry, clean state.

Engine Oil It is important to perform oil changes regularly in
accordance with the intervals specified in the
“Maintenance” booklet.
Engine oil consumption
It is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil
level at all, even after 600 miles (1,000 km) or
more. This is because the oil is gradually becom-
ing diluted with fuel or mo isture, making it appear
that the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater. If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to
lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level checked at every fuel filling.
– The oil pressure warning light is not an oil level indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if en-
gine rpm is above idle speed.
Engine Oil Level f Please see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 196.
f Regularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 157.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.3 quarts (1.25 liters).
Each segment of the display corresponds to ap-
prox. 0.42 quart (0.4 liter).

Topping off engine oil
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
f Keep engine oil out of children’s reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
f Always protect your skin by washing thorough-ly with soap and water. Caution!
Risk of damage from overflowing engine oil.
f Take care while checking and topping up
engine oil not to soil the luggage compartment or items of luggage.
Note
The Check Engine warning light may light up if the
cap of the oil filler open ing is opened while the
engine is running.
The oil inlet opening is lo cated in the rear luggage
compartment under the service flap.
1. Measure the oil level and read off the required top-up quantity on the on-board computer.
2. Switch off the engine. 3. Open the service flap by pulling the handhold.
4. Unscrew the oil filler cap.
5. Add at most 0.5 quar ts (0.5 liter) of engine oil
at a time.
Never add more engine oil than required
to reach the max. mark.
6. Close oil filler cap until you feel it reach its end
position.
7. Measure oil level again with the on-board computer. Switch off the engine.
8. If necessary, repeat the process and add more engine oil as required.
Engine Oil RecommendationPorsche recommends .
The right oil for your vehicle.
1) Generally, you can find details of the
manufacturer approvals on the oil containers or as
a notice displayed by the retailer.
The current approval status is also available from
your Porsche partner.
2) SAE viscosity class - Example: SAE 0W - 40
Specification 0W = Viscosity specification for
low temperatures (winter).
Specification 40 = Viscosity specification for
high temperatures.
3) For all temperature ranges.
4) For the temperature range over --13 °F (--
25 °C).Complies with

Brake Fluid LevelfPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 196.
f Use only new (unused) Original Porsche
brake fluid.
Warning!
Brake fluid is hazardous to your health, and
may be fatal if swallowed.
Brake fluid also attacks paintwork.
f Keep brake fluid out of children’s reach.
f Take care while topping off brake fluid not to
soil the luggage compartment or items of lug-gage.
Checking the brake fluid levelThe reservoir for the hydraulic braking and clutch
systems is located in the luggage compartment.
1. Open and remove cover flap A.
2. Regularly check the brake-fluid level on the transparent expansion tank through the
window B.
The fluid level should always lie between the
minimum and maximum marks. A slight decrease in the fluid level due to wear and
automatic readjustment of
the disc brakes is
normal.
If, however, the fluid level falls markedly or below
the minimum mark, the br aking system may have
developed a leak.
f Have the brake system checked without delay
at an authorized Porsche dealer.

Changing the brake fluid Brake fluid absorbs moisture from the air over
time. This accumulation of water lowers the boil-
ing point and, under certain operating conditions,
can affect the braking performance.
Therefore have the brake fluid changed in accord-
ance with the change intervals stated in the
brochure “Maintenance”. – The warning lights on the instrument panel and
on the on-board computer indicate an insuffi-
cient brake fluid level.
– If the warning light lights up on the instrument
panel and the warning message appears on
the on-board computer in combination with a
larger pedal travel, a brake circuit may have
failed.
If the warning lights should light up when
driving:
f Stop immediately in a suitable place.
f Do not continue driving.
Consult an authorized Porsche dealer.
