G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced 
vehicle control. Your vehicle’s ABS will not 
prevent this type of loss of control.iWhen you brake or stop, the transmis-
sion shifts down to a gear from which 
you can easily accelerate or take off.
!In the manual program modeM, the 
transmission will not upshift, even if 
the engine has reached its overrevving 
range. Shift up to the next gear before 
the engine has reached its overrevving 
range. Make absolutely certain that the 
engine speed does not reach the red 
marking on the tachometer 
(page 24). Otherwise the engine 
could be damaged which is not covered 
by the Mercedes-Benz Limited 
Warranty.

296 OperationDriving instructionsTelephones and two-way radios
Radio transmitters, such as a portable tele-
phone or a citizens band unit should only 
be used inside the vehicle if they are con-
nected to an antenna that is installed on 
the outside of the vehicle.
Refer to the radio transmitter operation in-
structions regarding use of an external an-
tenna.
Catalytic converter (Gasoline engine)
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.
Warning!
G
Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or 
personal injury.
!To prevent damage to the catalytic con-
verters, 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, which could po-
tentially 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.
