186 Driving and Driving Safety
Information Center differential lock
When the center differential lock C is fully
engaged, there is no longer any speed difference
between the front and rear axles. This makes it
easier for the vehicle to keep moving if, for
example, both wheels on the front axle lose
traction on a soft surface.
Information Rear differential lock
When the rear differential lock D is fully engaged,
there is no longer any speed difference between
the two rear wheels. This makes it easier for the
vehicle to keep moving if, for example, one drive
wheel on the rear axle loses traction on an icy road
or soft surface.
Information
– The selected off-road driving program remains
engaged even if the driving conditions change,
e.g. if the vehicle is then driven on the road.
The corresponding light-emitting diodes next
to the rocker switch stay on but the
transmission and chassis control systems
adapt to suit the changed driving conditions.
– A warning message appears on the instrument
panel if there is a fault in the gearshift system.
f Please see the chapter “OVERVIEW OF
WARNING MESSAGES” on page 139.
Recommended settings Sport mode
Function
The sports exhaust system is switched on and
a sportier car set-up is obtained when Sport mode
is switched on.
Interventions by the Porsche control systems are
intentionally shifted towards greater agility and
driving performance.
– PASM (Porsche Active Suspension
Management) is automatically changed to
Sport mode, resulting in a stiffer suspension
setup.
– PDCC (Porsche Dynamic Chassis Control) is
automatically set to Sport mode and this
further reduces the roll tendency of the
vehicle.
– The air suspension automatically changes to
the low level setting.
– The Tiptronic S transmission changes to
a sportier shift strategy.
The gear-changing points are shifted to higher
speed ranges. Upward shifts are initiated later
and deceleration shifts are performed earlier.
– The electronic accelerator pedal reacts sooner
and the engine is more responsive to throttle
inputs.
– Sporty engine tuning is activated.
