Notes:
The indicator lamp in the Information button¡
remains illuminated in red for approx. 10 seconds
during the system self-check after turning electronic
key in starter switch to position 2 (together with the
“SOS” button and the Roadside Assistance button).
See system self-check on page 192 when the indicator
lamp does not light up in red or stays on longer than
approximately 10 seconds.
If the indicator lamp in the Information button¡ is
illuminated continuously and there was no voice
connection to the Response Center established, then the
Tele Aid system could not initiate an Information call
(e.g. the relevant cellular phone network is not
available). The message “info – CALL FAILED” appears
in the multifunction display.
Information calls can be terminated using the
ìbutton on the multifunction steering wheel.Important!
If the indicator lamps do not start flashing after
pressing one of the buttons or remain illuminated (in
red) at any time, the Tele Aid system has detected a fault
or the service is not currently active, and may not
initiate a call. Visit your Mercedes-Benz Light Truck
Center and have the system checked or contact the
Response Center at 1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon as possible.
Upgrade Signals
Tele Aid system processes calls using the following
priority.
•Automatic emergency – First priority
•Manual emergency – Second priority
•Roadside assistance – Third priority
•Information – Fourth priority
Should a higher priority call be initiated while you are
connected, an upgrade (alternating) tone will be heard,
and the appropriate indicator lamp will flash. If certain
information such as vehicle identification number or
customer information is not available, the operator may
need to retransmit.

place the call. The navigation system (if engaged) will
continue to run. The display in the instrument cluster is
available for use and spoken commands are only
available by pressing the RPT button on the COMAND

Te ch n i c a l

Catalytic converter
Your Mercedes-Benz is equipped with monolithic type
catalytic converters, an important element in
conjunction with the oxygen sensors to achieve
substantial control of the pollutants in the exhaust
emissions. Keep your vehicle in proper operating
condition by following our recommended maintenance
instructions as outlined in your Service Booklet.Caution!
To prevent damage to the catalytic converters, use only
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should
be repaired promptly. Otherwise, excessive unburned
fuel may reach the catalytic converter causing it to
overheat, which could start a fire.
Wa r n i n g !
As with any vehicle, do not idle, park or operate
this vehicle in areas where combustible materials
such as grass, hay or leaves can come into contact
with the hot exhaust system, as these materials
could be ignited and cause a vehicle fire.

203 Emission control
Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Emission control
Certain systems of the engine serve to keep the toxic
components of the exhaust gases within permissible
limits required by law.
These systems, of course, will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the engine should,
therefore, be carried out only by authorized Mercedes-
Benz Light Truck Center qualified technicians. Engine
adjustments should not be altered in any way. Moreover,
the specified service jobs must be carried out regularly
according to Mercedes-Benz servicing requirements.
For details refer to the Service Booklet.
Wa r n i n g !
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon monoxide,
and inhaling it can cause unconsciousness and
lead to death.Do not run the engine in confined areas (such as a
garage) which are not properly ventilated. If you
think that exhaust gas fumes are entering the
vehicle while driving, have the cause determined
and corrected immediately. If you must drive under
these conditions, drive only with at least one
window fully open.

0The electronic key can be withdrawn in this position
only. The steering is locked when the electronic key
is removed from the starter switch. If necessary,
move steering wheel slightly to allow the locking
mechanism to engage.
In vehicles with automatic transmission, the
electronic key can be removed only with the selector
lever in position “P”. After removing the electronic key or with the electronic key in starter switch
position 0 or 1 the selector lever is locked in
position “P”.
1Most electrical devices can be operated. For detailed
information see respective subjects.

Te ch n i c a l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Important!
If the electronic key is left in the starter switch
position 0 for a extended period of time, it can no longer
be turned in the lock. In this case, remove electronic key
from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
starter switch. Do not leave the electronic key in starter
switch position 0.Notes:
A warning sounds when the driver’s door is opened
with the electronic key is in starter switch position 1
or 0.
If the electronic key cannot be turned in the starter
switch, the vehicle battery may not be sufficiently
charged. See battery on page 319 or jump starting on
page 321.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traf fic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power-
consuming devices, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.
