Driving instructions
Driving abroad
Abroad, there is an extensive 
Mercedes-Benz service network at your 
disposal. If you plan to drive into areas 
which are not listed in the index of a 
Mercedes-Benz Light Truck Center directo-
ry, you should request pertinent informa-
tion from an authorized Mercedes-Benz 
Light Truck Center.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.!
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 potentially 
start a fire.
