shaded sensor field, and no longer be indicated when
approaching it any closer (warning indicators go out).
Parktronic malfunction
All red segments of the warning indicators light up, and
a warning sounds for 3 seconds, if Parktronic does not
function properly.
A dirty sensor could be the reason. (See page 311 for
instructions on cleaning the sensors in the bumpers.)
After cleaning the sensors, turn electronic key in
steering lock to position 2. If the defect continues to be
displayed, have the system checked at your authorized

Malfunction and indicator lamps
in the instrument cluster
General information:
If a bulb in the instrument cluster fails to light up
during the bulb self-check when turning the electronic
key in steering lock to position 2, have it checked and
replaced if necessary.
On-board diagnostic system
Check engine malfunction indicator lamp
Engine malfunction indicator lamp. If the
“CHECK ENGINE” malfunction indicator
lamp comes on when the engine is running,
it indicates a malfunction of the fuel management
system, emission control system, systems which impact
emissions, or the fuel cap is not closed tight (check the
fuel cap). If the “CHECK ENGINE” lamp is illuminated
continuously and the vehicle is driving normally, you
may still drive the vehicle, however, in all cases, we
recommend that you have the system checked at your
authorized Mercedes-Benz Center as soon as possible. If the “CHECK ENGINE” lamp comes on continuously
and / or the vehicle is not driving normally, serious
damage can occur to the emission system. Please
contact your authorized Mercedes-Benz Center
immediately.
The Sequential Multiport Fuel Injection (SFI) control
module monitors emission control components that
either provide input signals to or receive output signals
from the control module. Malfunctions resulting from
interruptions or failure of any of these components are
indicated by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster and are
simultaneously stored in the SFI control module.
If the “CHECK ENGINE” malfunction indicator lamp
comes on, have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
With some exceptions, the control module switches off
the “CHECK ENGINE” malfunction indicator lamp if the
condition, causing the lamp to come on, no longer exists
during three consecutive cycles. See also page 244 for
fuel cap placement warning.

cluster displayPractical hints Car care Index Electronic stability program (ESP) — warning lamp
The yellow ESP warning lamp in the
speedometer dial comes on with the
electronic key in steering lock position 2. It
should go out with engine running.
See page 227 and 228 if the warning lamp lights up or
flashes when the vehicle is moving.
BAS / ESP malfunction indicator lamp
The malfunction indicator lamp for the ESP
is combined with that of the BAS.
The yellow BAS / ESP malfunction indicator
lamp in the instrument cluster comes on with the
electronic key in steering lock position 2. It should go
out with the engine running.
If the BAS / ESP malfunction indicator lamp remains
illuminated with the engine running, see page 223 for
notes on brake assist system (BAS) and page 228 for
notes on electronic stability program (ESP).ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in steering lock position 2 and
should go out with the engine running.
When the ABS malfunction indicator lamp symbol and
warning in the instrument cluster remains illuminated
while the engine is running, it indicates that the ABS
has detected a malfunction and has switched off. In this
case, the brake system functions in the usual manner,
but without antilock assistance.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps come on
with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.
Have the system checked at your authorized
Mercedes-Benz Center as soon as possible.
See page 225 for notes on antilock brake system (ABS).

cluster displayPractical hints Car care Index LIGHTING SYSTEMWhen the message appears after starting the engine, or
if it come on while driving, this indicates a failure in the
parking lamp, taillamp, stop lamp, or low beam
headlamp. See page 291 for instructions on replacing
bulbs.
If an exterior lamp fails, the message will appear only
when that lamp is switched on.
If a brake lamp fails, the message will appear when
applying the brake and stays on until the engine is
turned off.
Note:
If additional lighting is installed (e.g. auxiliary
headlamps etc.) be certain to connect into the fuse
before the failure indicator monitoring unit order to
avoid damaging the system.
