Adjust vehicle to normal level:
Stop vehicle and apply brake.
Close vehicle doors.
Tap the right-hand rocker switch on the center console in the appropriate direction until vehicle has reached the low level. Then adjust to the vehicle's
normal level. The middle indicator light next to the rocker switch is permanently on. If a further indicator light should come on, a different level is set.
To avoid level adjustment of the air suspension during alignment, switch off level adjustment and switch it back on again when the work is complete.
Information about wheel-alignment corrections for rear axle
Warning:
Risk due to malfunction in PSM control range if steering angle sensor is uncalibrated or incorrectly calibrated.
-
Injury and material damage possible.
-
Calibrate steering angle sensor with wheels in straight-ahead position using the Porsche System Tester.
-
The steering angle sensor actual value must be checked after a suspension alignment where no changes have been made to the wheel alignment
values.
The kinematic toe-in and caster cannot be adjusted!!
Camber and toe can be adjusted vis eccentric adjuster!
Information about wheel-alignment corrections for front axle
Warning:
Risk due to malfunction in PSM control range if steering angle sensor is uncalibrated or incorrectly calibrated.
-
Injury and material damage possible.
-
Calibrate steering angle sensor with wheels in straight-ahead position using the Porsche System Tester.
-
The steering angle sensor actual value must be checked after a suspension alignment where no changes have been made to the wheel alignment
values.
The steering-angle sensor must be calibrated if the previous wheel alignment values (on rear and/or front axle) were changed.

General procedure for suspension alignment
Information
-
Carry out suspension alignment with an optical or electronic wheel alignment tester!
-
The measurement procedures should betaken from the operating instructions for the wheel alignment tester used!
To exclude erroneous measurements, the following preconditions must be met before alignment and the following points should be given special
attention:
Curb weight of vehicle, i.e. vehicle in running condition, fully tanked with tire repair kit or spare wheel and tools.
Ball-joint and wheel-bearing play in order (wheel-bearing play cannot be adjusted).
Tire pressure in accordance with specifications, fairly uniform tire tread.
Quick-clamping holder for Cayenne (for the measured-value pickups) correctly fastened to the wheels.
Receiving surfaces for the quick-clamping holder on the wheels must be clean and flat. In particular, always accurately check the levelling surface on
the wheels before fitting the quick-clamping holders.
Strictly comply with maintenance intervals for measuring equipment and measuring platform. If the levelling of the measuring platform or of the
measuring area is done in-house, levelling equipment is required. A hose level is inadequate!
Skilled handling of measuring equipment and measuring platform.
