217 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 rec-
ommended maintenance instructions as
outlined in your Maintenance Booklet.
Emission control
Certain engine systems serve to keep the
toxic components of the exhaust gases
within permissible legal limits.
These systems, of course, will function
properly only when maintained strictly ac-
cording to factory specifications. Any ad-
justments on the engine should, therefore,
be carried out only by qualified
Mercedes-Benz Light Truck Center autho-
rized technicians. Engine adjustments
should not be altered in any way. More-
over, the specified service jobs must be
carried out regularly according to Mercedes-Benz servicing requirements.
For details refer to the Maintenance Book-
let.
!To prevent damage to the catalytic con-
verters, 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 and 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.
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness 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 win-
dow fully open at all times.

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

Fold wiper arms forward.

Clean the wiper blades inserts with a
clean cloth and detergent solution.Window cleaning

G
For safety reasons, switch off wipers and re-
move key from steering lock before cleaning
the wiper blades, otherwise the wiper motor
might suddenly turn on and cause injury.
!Fold the windshield wiper arms back
onto the windshield before turning the
key in the steering lock.
Hold on to the wiper when folding the
wiper arm back. If released, the force
of the impact from the tensioning
spring could crack the windshield.Warning!
