The tires should always be inflated to the rec-
ommended tire pressure. R
Remove unnecessary loads. R
Remove roof rack sw hen they are not needed.R
Warm up the engin eatl ow engin es peeds.R
Avoid frequen ta cceleration or braking.R
Have all maintenanc ew ork carried out as
indicated by the servic ei ntervals in the Main- tenance Booklet or by the servic ei nterval dis-
play.

take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefor en ever leave
the engin er unning in enclosed spaces with-
out sufficien tv entilation.
Certain engin es ystems are designed to keep
the level of poisonous component sine xhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .A lways have
work on the engin ec arried out at aq ualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
Ben zC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aq ualified specialist
workshop.

If ap ressure loss warning message appears
in the multifunction display: R
observe the instructions in the displa ym es-
sages ( Y
page 211).R
check the tire for damage R
if driving on, observe the following notes
The driving distance possible in run-flat mode is
approximately 50 miles (80 km) when the vehi-
cle is partiall yl aden. When the vehicle is fully
laden it is approximately 19 miles (30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon: R
vehicle speed R
road condition R
outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving conditions
or maneuvers, or it can be increased through a
moderate style of driving.
The driving distance possible in run-flat mode is
counted from the moment the tire pressure loss
warning appears in the multifunction display.
You must not exceed am aximum speed of
50 mph (80 km/h).
When replacing one or all tires, please observe
the following specifications for your vehicle's
tires: R
size R
type and R
the "MOExtended" marking
If at ire has gone flat and cannot be replaced
with aM OExtended tire, as tandard tire may be
used as at emporary measure. Make sure that
you use the proper size and type (summer or
winter tire).
Vehicles equipped with MOExtended tires are
not equipped with aT IREFIT kit at the factory. It
is therefore recommended that you additionally
equip your vehicle with aT IREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. AT IREFIT kit may be obtained from
aq ualified specialist workshop.
