Parking brake lever (arrows)
Parking brake force is mechanically trans-
ferred to the rear wheels by means of cables.
Use the parking brake only after the vehic-
le has come to a full stop.
To set the parking brake
Press in the release button (arrow) at the end
of the lever as you pull the lever up. The park-
ing brake engages as soon as you release the
button in the raised lever.
To release the parking brake
Pull the lever slightly up as you depress the
release button. Keep the button depressed
as you lower the lever.
WARNING
• Release the parking brake fully. A par-
tially engaged brake will overheat the
rear brakes, reduce their effectiveness
and cause excessive wear.
• Always set the parking brake when park-
ing your car. Move the selector lever to
"P" (Automatic transmission) or move
the gearshift lever to reverse or first gear
(Manual transmission). On hills also turn
the wheels toward the curb.
The central warning light and the parking brake
light will go out after the engine is started and
the parking brake is fully released (see "Cen-
tral warning light system").
Brakes
Functioning of brake system
Your Porsche is equipped with a power as-
sisted hydraulic dual circuit brake system with
disc brakes at the front and at the rear. Both
circuits function independently.
In the unlikely event of hydraulic failure of
one circuit, push the brake pedal down
firmly and hold it in that position. A me-
chanical linkage activates the second cir-
cuit, and you will be able to bring the
vehicle to a stop.
WARNING
Failure of one brake circuit will impair the
braking capability resulting in an increas-
ed stopping distance.
If one brake circuit has failed, the other will
still operate. However, you will notice an in-
creased pedal travel when you step on the
brake. Should you encounter such experience,
bring your vehicle safely to a full stop.
Avoid driving the vehicle and instead have
it towed to the nearest authorized Porsche
dealer.
