Economical Driving Indicator
(ECONOMY)
The indicator shows the fuel con­
sum ption tendency during various
driving modes.
High fuel consum ption is indicated if
the pointer moves into the red area;
economical driving is indicated when
it is in the black area. The indications
should only be compared when driv­
ing w ithin the same gear.
Do not com pare fuel consum ption
readings between different gears. The
following rule applies: If you drive at
equal speeds, the fuel consum ption is
lower in the higher gear, although in
this gear the pointer is more fre ­
quently in the red area.

Winter Driving

Have your car winterized at your
authorized MERCEDES-BENZ dealer
before the onset of winter.
• Engine oil change: If " year-round"
multigrade engine oil is not used,
be sure to use an SAE grade
based on ambient tem perature.
For recom m ended engine oil vis­
cosities refer to " Fuels, Coolants,
Lubricants, e tc." and last page.
• Check engine coolant an tico rro ­
sion/antifreeze concentration.
• Additive fo r the w indshield washer
and headlamp cleaning system :
Add MB Concentrate " S " to the
prem ixed w indshield w asher sol-
vent/anti-freeze w hich is form u­
lated fo r below freezing tem pera­
tures (see page 45).
• Test battery: Battery capacity
drops w ith decreasing ambient
tem perature. A well charged bat­
tery ensures that the engine can
always be started, even at low
ambient tem peratures.

tires on all fo u r wheels fo r the w in­
ter season. Observe perm issible
maximum speed fo r M + S radial
