Oh Dave I feel so used. After we have warned about this so many times, you a frequent poster and reader went and did it (Porsche even warns you in the manual on page 236 of the '06 manual)...but I'll give you credit for confessing. Also consider this from the manual "After the battery is connected or after an completely discharged battery is charged, the
multifunctional
PSM light lights up on the instrument panel and a message appears on the onboard computer to indicate a fault. This fault can be remedied with a few simple
steps:
1. Start the engine.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the multifunctional
PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest qualified
specialist workshop.
Have the fault remedied.
4. After the warnings disappear, stop the vehicle
in a suitable place, and perform adaptation of
the power windows.
To do this, close windows once with the rocker
switch.
Press front half of rocker switch upwards again
to store the final position of the windows in the
control unit."
Rapid charging can shorten battery life but I'd guess you will be o.k. if you take care of the battery from now on.

PSM - Porsche Stability Management
|
 |
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility. |
