Automatic Range Adjustment – Poor Road Surface/Off-road
Detection
The automatic range adjustment system includes a function for
detecting poor road surfaces/off-road conditions, which counteracts the
continual adjustment behavior by using a filter system that significantly
reduces actuation of the stepping motors or shutting them down
completely. Interfering signals which are superimposed over the sensor
signals as a result of the road surface (bumps and pot holes) are filtered
out while driving.
Automatic Range Adjustment – Chassis Variants
Two chassis variants are used in the Cayenne (steel spring and air
suspension). Two automatic range adjustment variants (coding) are
available due to the mechanical and electronic differences between the
chassis variants. These are adapted specifically to suit the relevant
chassis. The required parameters are assigned for all Cayenne models
using the vehicle's required components list.
Coding
The following components must be coded during a service upon delivery
of a new headlight.
Chassis:
• Steel springs
• Air suspension
Lights:
• Static cornering light
Country version:
• Left-hand drive
• Right-hand drive
• USA/Canada
Parameter Settings
The following parameters are set:
• Automatic range adjustment parameters (depending on the chassis
installed).
