Indicator and warning signals

Indicator lamps for left turn signal (A1e1) and right turn signal

(A1e2)
The signal in models 129, 140, 170, 202 comes from the

combination relay (turn signals with trailer coupling, rear

window defroster, wiper motor, anti-theft alarm system)

(N10/2), and in model 210 from the multifunction control

module (N10-1) or the driver's side signal acquisition and

actuation module (SAM) (N10/1).

In model 168 the entire turn signal control is located in the

instrument cluster (A1).

Brake fluid / parking brake warning lamp (A1e7)

The signal for the brake fluid comes direct from the brake fluid level switch (S11) (except model 163).

(The signal for the parking brake comes over CAN.)

Fuel reserve warning lamp (A1e4)
When the reserve fuel level is reached, this lamp lights up and

goes out again only after refueling is detected. If the vehicle is

refueled with the ignition ON, refueling is detected only if at

least 7 liters of fuel are added.

-----------------------------------------------------------------------------------------

AIRBAG OFF indicator lamp (A1e56), only model 163 except

I

The signal comes from the emergency tensioning retractor

(ETR) control module with airbag (AB, N2/2)

Generator charge indicator/warning lamp (A1e5)

See document: Terminal 61 and terminal 61e, charge indicator

lamp, exterior lamp failure, function

Seatbelt/backrest lock warning lamp (A1e9)

The seat belt warning lamp is only used in a few national

versions, and is actuated direct by a seat belt buckle switch
(normally closed contact). After engine start, the lamp flashes

for a short time (approx. 6 seconds).

In model 129 if this lamp fails to go out after flashing briefly, but

continues to shine constantly, then the seat backrest is not

locked.
Exterior lamp failure indicator lamp (A1e14)

The signal comes from the lamp failure monitor

See document: Terminal 61 and terminal 61e, charge indicator

lamp, exterior lamp failure, function
Hydraulic fluid level warning lamp (A1e37)
The signal comes direct from the ADS level control oil level

switch (S44).

GENERAL INFORMATION
GENERAL NOTES ON WORKING ON VEHICLES WITH LEVEL CONTROL/ADS - AH32.00-P-0002-01A
All models with code 216b, 216c, 217a, 480
Fig. 1: Identifying Box Wrench (116 589 00 17 00)

The following instructions should be followed when disconnecting and connecting pressure lines:
Clean contaminated line connections before disconnecting them. Seal disconnected lines and hoses and
connections to components immediately with blind plugs.
Only use open box wrench and special tool when loosening and tightening pressure lines to avoid damage to the
line connections.
Check the component concerned and line connections for leaks after assembly work on the suspension
system.
NOTES ON CHECKING OIL LEVEL ON VEHICLES WITH LEVEL CONTROL/ADS - AH32.00-P-0003-01A
All models with SA Code 217a/ 480
Observe the following prerequisites when checking the oil level in the oil reservoir:
1. The vehicle must be standing on its wheels.
2. Check the oil level when the vehicle is ready to drive:
Vehicle ready for use with oil and coolant reservoirs filled.
Full fuel tank - compensate for any missing fuel by placing additional weight in trunk.
Spare wheel and vehicle tool kit in vehicle.
Unladen vehicle. Remove any luggage, fuel canisters etc. from the vehicle.
On vehicles with level control /ADS, the oil level in the oil reservoir may fall below the "min." mark
on the oil dipstick when the vehicle is loaded.

Fig. 3: Identifying Tensioning Plates (163 589 00 63 00)
1. Pre-equip tensioning device.
Insert tensioning plates (01a) into tensioner (01) until they engage. Press pins (arrows) to remove the
clamping plates.
2. Pre-adjust tensioning device to approx. 130 mm (a). This makes it easier to insert the rear spring
Fig. 4: Identifying Tensioning Plates And Pins

3. Clamp tensioning device (01) horizontal in vise.
4. Insert rear spring (73) in the clamping plates so that the end of the winding of the rear spring is roughly
parallel with the upper edge of the clamping plates (arrows a).
Insert rear spring from the 5th to the 11th rear spring winding (counted from the side with the larger
winding diameter in the clamping plates (6 to 7 windings must be clamped).

5. Rotate rear spring by approx. a quarter of a revolution (counterclockwise) so that the end of the rear
spring winding is located approximately in the center of the clamping plate (arrow b).
6. Check whether the lugs of the clamping plates are above the rear spring windings (arrow c), if necessary
correct the position of the rear spring.
7. Compress rear spring.
