Gauge for Economical Driving
(ECONOMY)
The gauge for economical driving indi­
cates the fuel consumption tendency
during the various driving modes.
If, while driving, the pointer travels to
the right into the red field, this indicates
an increase in the mom entary fuel con­
sumption.
In order to drive economically you
should try to keep the pointer of the
gauge away from the red field as much
as possible in all gears.
Always select the highest possible
gear, e.g. 4th gear on level ground at
approximately 60 km/h/36 mph (selec­
tor lever position “ D ” on autom atic
transmission). Using 3rd or 2nd gears
(selector lever positions “ 3 ” or “ 2 ” on
automatic transmissions) can involve
an increased consumption of between
2 5 -8 0 % at this speed.
Engine Oil Consumption
Engine oil consumption can only be
determined after a certain mileage has
been covered. During the break-in pe­
riod, higher oil consumption may be
noticed and is normal.
Brake Pad Wear indicator Lamp
The brake pad wear indicator lamp in
the instrument cluster comes on when
the key in the steering lock is turned to
driving position 2 and it must go out
when the engine is running. If the indi­
cator lamp lights up during braking, this
shows that the front wheel brake pads
are worn down.
Have brake system checked in a
M ERCEDES-BENZ service station as
soon as possible.
Brake Fluid
Brake fluid should be changed once a
year, preferably in spring.
Only use brake fluid recommended
by us. For further information, refer to
“ Fuels, Coolants, Lubricants etc.” .
When the minimum mark on the
reservoir is reached, have the system
checked (brake lining thickness,
leaks).
Charge Indicator Lamp
Should the charge indicator lamp fail to
come on prior to starting when the igni­
tion key is in position 2 or should it fail
to go out after starting or during opera­
tion, this indicates a fault which must
be repaired at a MERCEDES-BENZ
service station as soon as possible.
When the charging indicator lamp
glows while the engine is running, the
V-belt may have been torn off which
makes the water pump also inopera­
tive. This may cause overheating and
damage to the engine. In this case
the V-belt must be renewed before
driving on.
Fuel Reserve W arning Lamp
The fuel reserve warning lamp will
come on when the ignition key is
turned to position 2, and will go out
after the engine is running.
If the warning lamp stays on after the
engine starts, or comes on while driv­
ing, it indicates that the fuel level is
down to the reserve quantity.
