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.

It is imperative that the wheel mounting bolts be 
fastened to a tightening torque of 80 ft.lb. (110 Nm) 
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”.
Rotating wheels
The wheels can be rotated according to the degree of 
tire wear while retaining the same direction of travel.
Rotating, however, should be carried out as 
recommended by the tire manufacturer, before the 
characteristic tire wear pattern (shoulder wear on front 
wheels and tread center wear on rear wheels) becomes 
visible, as otherwise the driving properties deteriorate.
Notes:
Thoroughly clean the inner side of the wheels any time 
you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread 
tires may adversely affect the handling characteristics 
and safety of the vehicle.
Dented or bent rims can cause tire pressure loss and 
damage to the tire beads. For this reason, check rims for 
damage at regular intervals. The rim flanges must be 
checked for wear before a tire is mounted. Remove 
burrs, if any.
Check and ensure proper tire inflation pressure after 
rotating the wheels. For tire inflation pressure see 
inside of fuel filler flap and also page 278.
Wa r n i n g !
Worn, old tires can cause accidents. If the tire tread 
is badly worn, or if the tires have sustained 
damage, replace them.When replacing rims, use only genuine 
Mercedes-Benz wheel bolts specified for the 
particular rim type. Failure to do so can result in 
the bolts loosening and possibly an accident.
