Adaptive cruise control.
Optional on all Cayenne models,
adaptive cruise control regulates
the speed of your vehicle in line
with that of the vehicle in front. To
do that, the system uses a radar
sensor in the central air intake
to monitor the road up to 200 m
ahead. If you approach another vehicle
that is travelling slower than
your selected cruising speed,
the system slows the engine or
gently applies the brakes (up to
3.5 m/s
2). This continues until the
distance that you have preset is
maintained. If heavier braking is
required, the driver has to actively
intervene. Your vehicle will now follow the one in front at a
reduced speed.
If the other vehicle decelerates
further, adaptive cruise control
will continue to reduce your speed
– even down to a halt. When the
road ahead is free once more,
the car automatically returns
to your selected cruising speed bet ween 30 and 210 km/ h
(19 and 130 mph). To pull away
after an automatic stop, simply
use the control lever or depress
the accelerator pedal.
For added safet y, the system also
readies the brakes whenever a
decreasing distance to the vehicle
in front is detected. Adaptive
cruise control and PSM (p. 66)
interact to prefill the brakes.
The system visually and audibly
alerts the driver in the event
of a critical
decrease in distance
and briefly tugs on the brakes.
Optional for all new Cayenne
models.
Lane Change Assist (LCA).
The optional Lane Change Assist
(LCA) system monitors the area
behind the vehicle and the blind
spot using radar sensors. At speeds of 30 km/ h (19 mph) or
more, the system alerts the driver
of a vehicle in the blind spot or
approaching quickly from behind
via a visual signal from the
exter
ior mirrors. This enhances
comfort and safet y, particularly
when driving on the motorway.
However, LCA does not actively
intervene in the
controlling of
the vehicle and can be deactivated
at any time.
Optional for all new Cayenne
models.
