374 Practical hintsWhat to do if …Lamps in instrument clusterGeneral information:
If any of the following lamps in the instru-
ment cluster fails to come on during thebulb self-check when switching on the igni-
tion, have the respective bulb checked and
replaced if necessary.Problem
Possible cause/consequence
Suggested solution
-
The yellow ABS indicator lamp
comes on while driving.
The ABS has detected a malfunction and has
switched off. The BAS and the ESP
® are also
switched off (see messages in the multifunc-
tion display).
The electrohydraulic brake system is still
functioning normally but without the ABS
available.
If the ABS control unit is malfunctioning, oth-
er systems such as the Parktronic system*,
Distronic*, or the automatic transmission
may also be malfunctioning.
Continue driving with added caution.
Wheels may lock during hard braking,
reducing steering capability.
Read and observe messages in the
multifunction display (
page 386).
Have the system checked at an autho-
rized Mercedes-Benz Center as soon
as possible.
Failure to follow these instructions in-
creases the risk of an accident.
The charging voltage has fallen below
10 volts. The ABS has switched off.
The battery may not be sufficiently charged.
Switch off electrical consumers that
are currently not needed, e.g. seat
heating.
If necessary, have the generator and
battery checked.
When the voltage is above this value
again, the ABS is operational again.
386 Practical hintsWhat to do if …Vehicle status messages in the multi-function display
Warning and malfunction messages ap-
pear in the multifunction display located in
the instrument cluster.
Certain warning and malfunction messag-
es are accompanied by an audible signal.
Address these messages accordingly and
follow the additional instructions given in
this Operator’s Manual.
Selecting the vehicle status message
memory menu in the control system
(page 153) displays both cleared and
uncleared messages.
High-priority messages appear in the mul-
tifunction display in red color.Certain messages of high priority cannot
be cleared from the multifunction display
using the reset button (
page 150) or
buttonj, k, ÿ or è on the
multifunction steering wheel.
Other messages of high priority and mes-
sages of less immediate priority can be
cleared from the multifunction display us-
ing the reset button (
page 150) or
buttonj, k, ÿ or è on the
multifunction steering wheel. They are
then stored in the vehicle status message
memory (
page 162). Remember that
clearing a message will only make the mes-
sage disappear. Clearing a message will
not correct the condition that caused the
message to appear.
Warning!
G
All categories of messages contain impor-
tant information which should be taken note
of and, where a malfunction is indicated, ad-
dressed as soon as possible at an autho-
rized Mercedes-Benz Center.
Failure to repair condition noted may cause
damage not covered by the Mercedes-Benz
Limited Warranty, or result in property dam-
age or personal injury.Warning!
G
No messages will be displayed if either the
instrument cluster or the multifunction dis-
play is inoperative.
Contact the nearest authorized
Mercedes-Benz Center.

With the seat unoccupied and the ignition turned on,
the 75 indicator lamp on the center console should illuminate and re-
main illuminated, indicating that the OCS (

pied. Wait at last 60 seconds for the system to complete the necessary check
cycles and to make sure neither message appears in the multifunction display.
If above conditions are met, you can occupy the front passenger seat again. De-
pending on the front passenger classification sensed by the OCS (
page 81), the
75 indicator lamp will remain illuminated or go out.
If above conditions are not met, the system is not working properly. Have the sys-
tem checked as soon as possible by an authorized Mercedes-Benz Center.
Warning!

If the
75
indicator lamp remains
out even after performing the above correc-
tive steps, do not have any children 12 years
old and under and other small individuals
use the front passenger seat until the sys-
tem has been repaired.

Bleeding the fuel system (Diesel engine only)
Bleeding the fuel system (Diesel engine only)
Allowing the vehicle to be driven until the
fuel tank is empty is not recommended. If
this occurs, air may be pulled into the fuel
system. If this happens, theú malfunc-
tion indicator lamp (USA only) or the
±malfunction indicator lamp (Canada
only) comes and it may be possible that
the engine will not start immediately after
you refuel the vehicle.
After refueling:
Turn the SmartKey in the starter switch
to position2 for at least 30 seconds.
Return the SmartKey in the starter
switch to position0.
Turn the SmartKey in the starter switch
to position3 and hold it there for up to
60 seconds, i.e. until the engine is run-
ning surge-free.If the engine does not start:
Try to start the engine again without in-
terruption for a maximum of 60 sec-
onds until it is running smoothly.
If the engine still does not start even after
this attempt, do not make any further at-
tempts to start the engine. Contact an
authorized Mercedes-Benz Center.
iWhere theú malfunction indicator
lamp (USA only) or the± malfunc-
tion indicator lamp (Canada only) in the
instrument cluster has been illuminat-
ed for the above condition, it will re-
main illuminated until the engine was
cycled on and off four times in a row.
456 Practical hintsJump starting
Start engine of the vehicle with the
charged battery and run at idle speed.
Connect negative terminals4 and2
of the batteries with the jumper cable.
Clamp cable to charged battery4
first.
Start the engine of the disabled vehi-
cle.Now you can again turn on the electrical
consumers. Do not turn on the lights under
any circumstances.
Remove the jumper cables first from
negative terminals2 and4 and then
from positive terminals1 and3.
Now you can turn on the lights.
Have the battery checked at the near-
est authorized Mercedes-Benz Center.
iThe message
Malfunction - electric
consumers switched off
may appear
in the instrument cluster. It will disap-
pear as soon as the battery is suffi-
ciently charged.
!Do not tow-start the vehicle.
