With the electronic key removed and the driver’s door
open, a warning sounds and the message “SWITCH OFF
LIGHTS” in the multifunction indicator appears if the
vehicle’s exterior lamps (except standing lamps) are not
switched off.
Fog lamps will operate with the parking lamps and / or
the low beam headlamps on. Fog lamps should only be
used in conjunction with low beam headlamps. Consult
your State or Province Motor Vehicle Regulations
regarding allowable lamp operation.
Fog lamps are automatically switched off when the
exterior lamp switch is turned to position D.Daytime running lamps (Canada only)
When the engine is running and the selector lever is in
a driving position, the low beam headlamps (includes
parking lamps, side marker lamps, taillamps and
license plate lamps) are automatically switched on.
When shifting from a driving position to position “N”
or “P”, the low beam switches off (2 seconds delay).
For nighttime driving the exterior lamp switch should
be turned to position B to permit activation of the
high beam headlamps.
Night security illumination
When exiting the vehicle after driving with the exterior
lamps on, they switch on again for added illumination
for approximately 30 seconds after closing the last door.
The lamp-on time period can be changed at your
Mercedes-Benz Center.

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 (e.g.
malfunction of the fuel management system or running out of fuel), 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 230 for
fuel cap placement warning.
An on-board diagnostic connector is located in the
passenger compartment near to the parking brake
pedal, allowing the accurate identification of system
malfunctions through the readout of diagnostic trouble
codes.

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 219 if the warning lamp lights up or f lashes
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 215 for
notes on the brake assist (BAS) and page 219 for notes
on the electronic stability program (ESP).ABS malfunction indicator lamp
The ABS malfunction indicator lamp in the
instrument cluster comes on with the
e l e c tr o n ic key i n ste e ri n g l oc k p os i ti o n 2 a n d
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 of f. Wh en t he voltage is a bove th is value a gain,
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.
