Parktronic system malfunction
If only the red distance segments illumi-
nate and a acoustic warning sounds,
there is a malfunction in the Parktronic
system. The Parktronic system will auto-
matically switch off after 20 seconds and
the indicator lamp in the Parktronic switch
comes on.

Have the Parktronic system checked
by an authorized Mercedes-Benz
Center as soon as possible.If only the red distance segments illumi-
nate and no acoustic warning sounds, the
Parktronic system sensors are dirty or
there is an interference from other radio or
ultrasonic signals. The Parktronic system
will automatically switch off after 20 sec-
onds and the indicator lamp in the Park-
tronic switch comes on.

Switch off the ignition (

or

Check the Parktronic system operation
at another location to rule out interfer-

303 Operation
Driving instructions
Catalytic converter
Your Mercedes-Benz is equipped with
monolithic-type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper
operating condition by following our
recommended maintenance instructions
as outlined in your Maintenance Booklet.
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 ac-
cording to factory specifications. Any ad-
justments to the engine should therefore
be carried out only by qualified
Mercedes-Benz Center authorized techni-
cians.
Engine adjustments should not be altered
in any way. Moreover, the specified service
jobs must be carried out regularly accord-
ing to Mercedes-Benz servicing require-
ments. For details refer to the
Maintenance Booklet.
!To prevent damage to the catalytic
converters, only use 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 and potentially
start a fire.
Warning!
G
As with any vehicle, do not idle, park or op-
erate this vehicle in areas where combusti-
ble 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.

354 OperationVehicle careAutomatic car wash
You can have your car washed in an auto-
matic car wash from the start. Automatic
car washes without brushes are prefera-
ble.
If the vehicle is very dirty, prewash it be-
fore running it through the automatic car
wash.Ornamental moldings
For regular cleaning and care of ornamen-
tal moldings, use a damp cloth.
!Do not clean your vehicle in an auto-
matic touchless car wash which uses
caustic spray. Otherwise the caustic
spray will damage the paint or orna-
mental moldings.
!Due to the width of the vehicle, fold in
exterior rear view mirrors prior to run-
ning the vehicle through an automatic
car wash to prevent damage to the
mirrors.
Make sure that the combination switch
is set to0 (
page 53). Otherwise, the
rain sensor could activate and cause
the wipers to move unintentionally.
This may lead to vehicle damage.
iAfter running the vehicle through an au-
tomatic car wash, wipe any wax off of
the windshield (
page 356). This will
prevent smears and reduce wiping
noise which can be caused by residual
wax on the windshield.
When leaving the car wash, make sure
that the mirrors are folded out. Other-
wise they may vibrate.
!Do not use chrome cleaner on orna-
mental moldings. Although ornamental
moldings may have chrome appear-
ance, they could be made of anodized
aluminum that will be damaged when
cleaned with chrome cleaner. Instead,
use a damp cloth to clean those orna-
mental moldings.
For very dirty ornamental moldings of
which you are sure are chrome-plated,
use a chrome cleaner. If in doubt
whether an ornamental molding is
chrome-plated, contact an authorized
Mercedes-Benz Center.

Vehicle care
Headlamps, tail lamps, side markers,
turn signal lenses
Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water.Cleaning the Parktronic system*
(Canada only) sensors
1Parktronic system* sensors in front
bumper

Use a mild car wash detergent, such as
Mercedes-Benz approved Car Sham-
poo, with plenty of water and a soft,
non-scratching cloth to clean
sensors1 on the bumpers.
!Only use window cleaning solutions
that are suitable for plastic lamp lens-
es. Window cleaning solutions which
are not suitable may damage the plas-
tic lamp lenses of the headlamps.
Therefore, do not use abrasives, sol-
vents or cleaners that contain solvents.
Never apply strong force and only use a
soft, non-scratching cloth when clean-
ing the lenses. Do not attempt to wipe
dirty lenses with a dry cloth or sponge.
Otherwise you may scratch or damage
the lens surface.
!Do not apply strong pressure to the
sensor covers. Applying strong pres-
sure may damage the sensor covers.
Follow the instructions provided by the
power washer manufacturer on main-
taining a distance between the vehicle
and the nozzle of the power washer.!To prevent scratches, never apply
strong force and only use a soft,
non-scratching cloth when cleaning the
sensors. Do not attempt to wipe dirty
sensors with a dry cloth or sponge.
