The raised level setting switches off at speeds exceeding
approximately 75 mph (120 km / h), or if vehicle speed
is operated between 50 mph (80 km / h) and 75 mph
(120 km / h) for approximately 5 minutes. The message

cluster displayPractical hints Car care Index Parking assist (Parktronic)
The Parktronic system assists the driver during parking
maneuvers. It visually and audibly indicates the relative
distance between the vehicle and an obstacle.
The front area of the vehicle is monitored when driving
forward. When reversing or with the gear selector lever
in position “N”, the front as well as the rear areas are
monitored.
With the electronic key in starter switch position 2,
Parktronic engages automatically at speeds up to
approximately 10 mph (15 km / h) and deactivates
during higher speeds.
Parktronic can be switched off by a control switch
located in the center console. It engages automatically
again when starting the engine.
See page 289 for Parktronic switch.
Wa r n i n g !
Parktronic is a supplemental system. It is not
intended to nor does it replace the need for extreme
care. The responsibility during parking and other
critical maneuvers rests always with the driver.Special attention must be paid to objects having
smooth surfaces or low silhouettes (e.g. trailer
couplings, painted posts, or street curbs). Such
objects may not be detected by the system and can
damage the vehicle.The operational function of the Parktronic can be
affected by dirty sensors, especially at times of
snow and ice. See page 378 for notes on cleaning
the parktronic system sensors.Interference caused by other ultrasonic signals
(e.g. working jackhammers or the air brakes of
trucks) can cause the system to send erratic
indications, and should be taken into
consideration.

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 378 for
instructions on cleaning the sensors in the bumpers.
After cleaning the sensors, turn electronic key in starter
switch to position 2. If the defect continues to be
displayed, have the system checked at your authorized
Mercedes-Benz Center.Parktronic switch

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.
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 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.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
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.
