Information
This description refers to the left headlight, and for a better representation, the illustrations of removal are in sectional view.
Information
- When working, carrying out tests or adjusting headlights on the Cayenne or when it is in the workshop, a battery charging unit with a rated current of at least 40 A must be connected.
- As soon as the vehicle is unlocked, e.g. the vehicle is in the workshop or salesroom, it must be trickle-charged with a battery charging device.

Adjusting main headlights
The vehicle must be on a horizontal surface.
Make the adjustment with the regulator switch set to 0 (headlight beam adjustment).
Make the adjustment with the vehicle ready for driving (fuel tank full, driver's seat occupied by a person or 75 kg; the tyre pressure must correspond to the specified values) using a headlight adjustment unit.
Bi-Xenon main headlight
Information
- Read out and erase the HBA fault memory before each adjustment of the headlights. To do this in the Porsche System Tester, select the Special functions menu, then select the HBA left menu or the HBA right menu, read out the fault memory, and erase it.
Information
- If a new Bi-Xenon main headlight has been installed, the control unit must also be calibrated for level control before any adjustments are made.
Under menu item "Calibration", the headlight beam adjustment (HBA) control unit is adapted to the current conditions relating to vehicle position. During calibration the existing vehicle position is stored as zero position.
Following calibration, the main headlight setting must be checked and adjusted if necessary.
Calibration must be performed if changes were made that can change the position of the angle sensors:
- Complete main headlight
- HBA (Bi-Xenon) control unit
- HBA angle sensor (front and rear compression)
- Running gear components
- Accident damage
Information
- Whenever the coding is changed in the menu item "Change coding", the ignition must always be switched off afterwards and the key removed.
- After the ignition is switched on again, the new coding of the control unit is updated and the stored faults can be erased.
Information
- If the coding does not match the vehicle equipment, faults may be displayed that are not really present.
1. Turn on the ignition, turn on dipped beam and high beam headlights.
2. Check setting and adjust if necessary.
3. Adjust main headlights.
3.1. Set headlight adjustment unit to 10 cm/10 m (1 %).
Information
- The distance between the headlights and the adjustment unit should be as small as possible.
- It should not exceed 30 cm, because at greater distances it is no longer possible to define the formation of the light/dark limit in the adjustment unit clearly.
- The description refers to the left headlight.
3.2. With this alignment, preference must be given to the central zone around the salient point of the light/dark limit.
3.3. First, adjust the vertical/side setting of the dipped beam/high beam using an Allen key (6 mm) -arrows-.
Vertical/side dipped beam setting
3.4. To do this, line up the light/dark limit line running upwards at an angle on the right-hand side with the dotted 15° line on the adjustment unit.
Right, vertical section of the light/dark limit
3.5. Next, adjust the horizontal setting of the dipped beam using an Allen key (6 mm) -arrows-.
Horizontal dipped beam setting
Information
- The illustration refers to the halogen headlight.
3.6. To do this, line up the left, horizontal section of the light/dark limit (when driving on the right) with the dotted horizontal line on the adjustment unit.
Left, horizontal section of the light/dark limit
4. For Bi-Xenon main headlights, the ignition must be switched off and on again after the adjustment has been made with the lights switched on.
5. After this, the adjustment must be checked again.
