reactivatedAfter driving a few minutes the system
verifies that the current tire inflation
pressures are within the system’s
specified range. Afterwards the current
tire inflation pressures are accepted as
reference pressures and then moni-
tored.
If you wish to cancel activation:
Press the çbutton.
iReactivate the TPMS after adjusting
the tire inflation pressure to the infla-
tion pressure recommended for the
vehicle operating condition. Tire pres-
sure should only be adjusted on cold
tires. Observe the recommended tire
inflation pressure on the placard on the
driver’s door B-pillar (
page 328).
Some vehicles may have supplemental
tire pressure information for driving at
high speeds (
page 334) or for vehicle
loads less than the maximum loaded
vehicle condition. If such information is
provided, it can be found on the inside
of the fuel filler flap.

358 OperationMaintenanceWe strongly recommend that you have
your vehicle serviced by an authorized
Mercedes-Benz Center, in accordance with
the Maintenance Booklet at the times
called for by the maintenance service indi-
cator display.
Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in ve-
hicle damage not covered by the
Mercedes-Benz Limited Warranty.Maintenance service indicator
message
The maintenance service indicator will no-
tify you when your next maintenance ser-
vice is due.
Starting approximately 1 month before
maintenance service is due, one of the fol-
lowing messages will appear in the multi-
function display while you are driving or
when you switch on the ignition (example
service A):Service A in XXXX Miles (Km)
Service A in XXX Days
Service A in X Day
Service A due now
The maintenance services will be indicated
by showing a service type A through type H
in the multifunction display. Types A
through H are classified based on estimat-
ed time needed to perform the mainte-
nance service, ranging:
from
Service A(approximately 1 hour)
toService H(approximately 8 hours)
Refer to Maintenance Booklet for a listing
of maintenance services and intervals they
need to be performed at.

Clearing the maintenance service
indicator message
The maintenance service indicator mes-
sage is automatically cleared
after approximately 10 seconds when
you switch on the ignition or when
reaching the service threshold while
driving
after approximately 30 seconds, once
the suggested maintenance service
term has passedYou can also clear it yourself:
Press the reset button 1 on the left
side of the instrument cluster.
The maintenance service indicator
message is cleared and the standard
display appears in the multifunction
display (
page 155).
iVehicles equipped with FSS PLUS
(Flexible S
ervice S
ystem PLUS) only
(Canada vehicles): The interval be-
tween maintenance services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

360 OperationMaintenanceMaintenance service term exceeded
If you have exceeded the suggested main-
tenance service term, you will see the fol-
lowing message in the multifunction
display:Service A exceeded by XXXXX Miles (Km)
Service A exceeded by XXX Days
Service A exceeded by X Day In addition, a signal sounds when the mes-
sage appears.
Any authorized Mercedes-Benz Center will
reset the maintenance service indicator
following a completed maintenance
service.Calling up the maintenance service
indicator display
You can call up the maintenance service
indicator display at any time to check
when the next maintenance service is due.
Switch on the ignition (
page 36).
Press button è or ÿ on the mul-
tifunction steering repeatedly until the
standard display appears in the multi-
function display (
page 155).
Press button k or j until the
maintenance service indicator display
with the service symbol 9 and the
service deadline appears in the multi-
function display.
iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the maintenance
service indicator. To arrive at the true
maintenance service deadline, you will
need to subtract these days from the
days shown in the maintenance service
indicator message or maintenance ser-
vice indicator display.
Do not confuse the maintenance ser-
vice indicator with the engine oil level
indicator :.

372 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 multifunction
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 Distronic*, or the auto-
matic 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 383).
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.

The red brake warning lamp
comes on while driving and
you hear a warning sound.
You are driving with the park-
ing brake set.
Release the parking brake.
Observe the additional message in
the multifunction display.
The red brake warning lamp
comes on while driving.
There is a malfunction in
the electrohydraulic brake
system.
There is insufficient brake
fluid in the reservoir.
Risk of accident! Do not drive any fur-
ther. Consult a Mercedes-Benz
Service Center. Under no circum-
stances should you top up the brake
fluid. This will not solve the problem.
Warning!
G
Driving with the brake warning lamp illumi-
nated can result in an accident. Have your
brake system checked immediately if the
brake warning lamp stays on. Do not add
brake fluid before checking the brake
system.
Overfilling the brake fluid reservoir can re-
sult in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You
can be seriously burned.
!If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the
brake system checked for brake pad
thickness and leaks.

H
Combination low tire pres-
sure/TPMS malfunction telltale

The TPMS* detects a loss of pressure in at
least one tire.
Carefully bring the vehicle to a halt,
avoiding abrupt steering and braking
maneuvers. Observe the traffic situation
around you.
Read and observe messages in the mul-
tifunction display.
If the tire inflation pressure in the respec-
tive tire(s) has (have) been corrected, the
combination low tire pressure/TPMS mal-
function telltale goes out after few minutes
driving.

There is a malfunction in the TPMS*.
Read and observe messages in the mul-
tifunction display.
Have the TPMS* checked by an
authorized Mercedes-Benz Center.
After the malfunction has been remedied
the combination low tire pressure/TPMS
malfunction telltale goes out after few
minutes driving.
