Global positioning system (GPS)
By means of the appropriate receivers,
satellite signals supply information on the
geographical position of the vehicle. These
signals are compared with a digital map and
used both to determine the position of the
vehicle and for its route guidance.
Handling control
The handling control switch affects the
Proactive Chassis Control II system.
Hill hold control
Hill hold control prevents roll-back on hill
starts. The brake system automatically
applies the brakes until the accelerator is
pressed.
Ignition cut
Ignition cut operates during manual upshifts
in powertrain mode.
When calling for an upshift under hard
acceleration, ignition is interrupted (cut) in a
defined number of engine cylinders. This
rapidly decrease the engine torque and
engine speed, allowing faster upshifts to be
achieved.
Inertia push
When Non-Active is selected or within Track
powertrain mode when calling for an upshift
at high engine speeds under hard
acceleration, inertia push delivers greater
acceleration. Under normal driving
conditions, outside of inertia push when
maximum performance is not called for, the
engine and transmission speeds are aligned
for a smooth seamless upshift. However,
with inertia push, the clutch holding the
next gear is engaged with greater force and
the engine speed is not allowed to decrease
fully, therefore utilising the inertia of its
internal rotating masses. This in turn
provides a torque impulse as the gear is
engaged aiding acceleration and maximising
performance.
Keyless entry
Keyless entry allows the driver to unlock the
vehicle and disarm the alarm by simply
opening the door when the key fob is within
1.2 m (3 ft 11 in) of the door sensors.
Launch control
Launch control is designed to give the
maximum acceleration performance from a
standing start.
Motorway function lighting
The motorway function lighting improves
the headlamp illumination range when the
vehicle speed exceeds a predetermined
threshold.
Parking sensors
The parking sensor system comprises four
ultrasonic sensors in the front bumper, four
ultrasonic sensors in the rear bumper and
two sounders. When the parking sensors
detect an obstructions while manoeuvring,
the sounders provide an audible warning.
Performance shift cue (PSC)
PSC is an audible shift indicator, which will
sound to indicate that an upshift is required
to maintain optimum performance.
Rear view camera (RVC)
The RVC is mounted in the centre of the rear
bumper. The live video feed is displayed on
either the Driver Display or the Central
Display when the function is active.
Seamless shift gearbox
The seamless shift gearbox is a 7 speed, dual
clutch gearbox. Gear changes can be fully
automatic or driver controlled. The gear
changes are almost instantaneous. It is this
