Suspension Control Module

Read Before Installation
Warning:
This Lowering Module should be installed by an individual with
extensive knowledge in electronics, including: wire identification,
extracting and inserting pins from connector housing.
We are not responsible for any damage to the Lowering Module
or related devices due to improper installation.
Ride Height:
To retain proper ride comfort and to avoid damage to suspension
components please follow these minimum recommended height
adjustments:
All non-AMG Mercedes models should use a setting of 3 or
higher.
AMG cars are lower than their Mercedes counterparts. With this
in mind it is recommended that AMG cars use a ride height
setting of 5 or higher.
Lower settings can be used for show purposes but are not recommended for everyday driving.
In some models the door must be closed in order for the
Airmatic or ABC system to operate. This is a safety function and
is normal on those vehicles.
Technical Support:
For further information, please contact

NOTES:
Ride Height Adjustment
Function Switch (see installation instructions):
0 = Suspension Module Off (LEDs 1, 2, 3, 4 stay On)
1 = Suspension Module On (LED 4 is ON, LEDs 1, 2, 3 blink)
2 = Suspension Module On (LED 4 is ON, LEDs 1, 2, 3 blink)
3 = Suspension Module On (LEDs 1, 2, 3, 4 blink)
4, 5, 6, 7 = Suspension Module Off (LEDs 1, 2, 3, 4 stay On)
- If a Remote Control is being used, refer to the operating instructions in its user manual.
- It is quite common that even before the installation individual wheels are not at the same
level. This is more noticeable when the vehicle is lowered. Small differences can be manually adjusted by rotating the individual Wheel Switches. Larger differences should be corrected at the dealer using proper equipment and procedure. Before going to the dealer,
remember to turn off the Air Suspension Control Module by rotating the Function Switch
(black button) to position 0. Once back from the dealer, rotate the Function Switch back
to original position 1 or 2, as described in the Step-by-Step Installation.
- The proceeding lowering values are an approximation and will vary from wheel to wheel
and vehicle to vehicle:
Wheel Height Adjustment Switch positions
7: lower by
3/8“
[10 mm]
6: lower by
3/4“
[20 mm]
5: lower by
1“
[25 mm]
4: lower by
1 1/8“
[30 mm]
3: lower by
1 3/8“
[35 mm]
2: lower by
1 1/2“
[40 mm]
1: lower by
1 3/4“
[45 mm]
0: lower by
2“
[50 mm]
