2003-2008 BRAKES Anti-Lock Brake System (ABS) 45 IN INFORMATION ON PSM - AS OF MY 2003 (CAYENNE TIP, CAYENNE S TIP, CAYENNE TURBO, CAYENNE TURBO S) INFORMATION ON PSM PSM is an active control system to stabilize the vehicle at the limit of driving dynamics. Sensors continuously determine:  Vehicle speed  Direction of travel (steering angle)  Transverse acceleration  Longitudinal acceleration  Rate of turn Off-road PSM When the Low Range/Off-road programmer is switched on, an off-road PSM specially adapted for off-road terrain to improve traction is automatically activated. At speeds below 35 km/h, the off-road PSM reacts later in the case of under or oversteering and improves the steering control. Switching off PSM Press the PSM switch. The PSM switches off after a short delay. When the PSM is off, the PSM OFF warning light in the instrument panel and the indicator light in the switch are lit.  When braking, the vehicle is also stabilized when the PSM is switched off!  One-sided wheel spin is also prevented when the PSM is switched off!  On Tiptronic vehicles, the slip upshift function is switched off when PSM is switched off . Refer to Characteristic features of Tiptronic vehicles (slip upshift) . The PSM should always be switched on for normal driving. In the following exceptional cases, it can be advantageous to switch off the PSM temporarily: - On a loose surface and in deep snow NOTE:  The PSM (Porsche Stability Management) is automatically ready/switched on after each engine start. 2006 Porsche Cayenne Turbo 2003-2008 BRAKES Anti-Lock Brake System (ABS)

- When rocking the vehicle free - When using snow chains - On extremely difficult terrain (if one or more wheels have little or no road grip - engine performance is reduced) Switching PSM back on Press the PSM switch. The PSM switches on after a short delay. Characteristic features of Tiptronic vehicles (slip upshift)  When a maximum permissible speed difference between front and rear axle is exceeded, the integrated slip monitoring shifts into the next highest gear. This increases the driving stability on slippery roads.  When PSM is switched off, the slip monitoring (slip upshift function) is also switched off. In this way, the Tiptronic enables an active sporty driving style even when the friction coefficient is low as is the case with manual transmission vehicles. 45 IN INFORMATION ON PSM - AS OF MY 2003 (CAYENNE MAN, CAYENNE S MAN) INFORMATION ON PSM PSM is an active control system to stabilize the vehicle at the limit of driving dynamics.

REMOVING HYDRAULIC UNIT  Any damp connector must be wiped dry before being disconnected from the connector on the hydraulic unit. If necessary, provide the connector with a suitable protector.  Brake fluid on electrical contacts (even thinned brake fluid) leads to corrosion and may cause faults in the system.  The brake lines must not be bent in the area of the hydraulic unit.  Clean the interfacing points of the brake lines, but not with cleaning agents.  Rinse off any brake fluid emerging thoroughly with water. NOTE:  When fitting the hydraulic connections, the electric plug connections on the control units must remain connected as long as possible. This prevents the plug connections on the hydraulic unit or in the connectors inside from being splashed with brake fluid or water. 2006 Porsche Cayenne Turbo 2003-2008 BRAKES Anti-Lock Brake System (ABS)
