300 OperationDriving instructionsCatalytic 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.

Vehicle care
Cleaning the Parktronic system*
sensors
1Parktronic system* sensors
Clean the sensors1 on the bumpers
using a mild car wash detergent, such
as Mercedes-Benz approved Car Sham-
poo, with plenty of water and a soft,
non-scratchy cloth.
When using a steam cleaner or power
washer, aim nozzle only briefly from a min-
imum distance of 12 in (30 cm) at
sensors1.Do not apply strong pressure to the sensor
cover, applying strong pressure may dam-
age the sensor cover.
To prevent scratches, never apply strong
force and only use a soft, non-scratchy
cloth when cleaning the sensor. Do not at-
tempt to wipe dirty sensors with a dry cloth
or sponge.Wiper blades

Fold wiper arm forward until it snapes
into place.

Clean the wiper blade inserts with a
clean cloth and detergent solution.Warning!
G
For safety reasons, switch off wipers and
remove SmartKey from starter switch
(vehicles with KEYLESS-GO*: make sure the
vehicle's on-board electronics have status 0) before cleaning the wiper blades.
Otherwise, the wiper motor could suddenly
turn on and cause injury. !Fold the windshield wiper arms back
onto the windshield before turning the
SmartKey in the starter switch.
Hold onto the wiper when folding the
wiper arm back. If released, the force
of the impact from the tensioning
spring could crack the windshield.
