202 as of 1.8.96,

208 up to 31.7.99,

210 as of 1.6.96 up to 30.6.99

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.)

Low windshield washer fluid level warning lamp (A1e13) except

models 163 and 168

3.99
See

document: Displaying coolant level, function

Coolant level and temperature warning lamp (A1e11) model 168

as of 9.99
See

document: Displaying coolant level, function

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).

ADS warning lamp, suspension (A1e27) The signal comes from the ADS control module, suspension
(N51).

SRS airbag malfunction indicator lamp (A1e15)
The signal comes from the emergency tensioning retractor

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