374 Practical advice
Flat tyrei
The maxim umdistance can beincreased
co nsiderably by using TIREFIT before starting
ru n-flat mode. Ifthe type of damag eis suc h that
TIREFIT cannot seal the tyre, you can still drive
the maxim um possible distance in run-flat mode. i
Ifyo u are replacing oneor more tyres, make
sure you usetyres with the "MOExtended” mark
and which are the specified size for the vehicle.
If you are replac ing one ormo re rims, make
sure you use rims approved for use with
"MOExtended” tyres and which are the specified
size for the vehicle. G
Risk of accident The handling characteristics of your vehicle
ar e adversely affected in run-flat mode, for
example:
! when cornering
! when braking
! when accelerating suddenly
You should therefor eadapt your driving
style accordingly and avoid making sudden
st eering movem ents, accelerating suddenly
and driving over obstacles (kerbs, pot holes,
off-road). The applies especially ifthe vehi-
cle is heavily laden.
The distance that can be tra velled in run-flat
mode depends la rgely on the loads placed
on the vehicle. Speed, load, sudd enacceler-
ation, road-surf aceco nditions, outside tem-
peratures, etc. can considerably reduce this
distance, whereas a conservative dr iving
st yle may inc reaseit. Run-fla
tmodemust bestopped in the event
of:
! bangi ng noises
! the vehicle shaking
! smoke development accomp anied by
the smell of rubber
! ESP continuously intervening
! tears in the tyre sid ewalls
After driving in run-flat mode, you must have
the rim checked to see if it can still be use d.
For this purpose, visit a qua lified specialist
workshop which has th e necessary special-
ist knowledge and tools to carry out the
work required. The flat tyre must be re-
placed inany case.
Mercedes -Benz recommends that you use a
Mercedes -Benz Service Centre for this pur-
pose. Inparticular, work relevant to safety
or on safety-relate dsystems must be car-
ried out at a qualified specialist workshop. 209en_d2.boo Seite

416 Technical data
Service products and capacities
The antifreeze and corrosion inhibitor con-
centration in the cooling system should:
! be at least 50%. This will pro tect the
cool ing sy stem against freezing down
to approximately –37 °C.
! not exceed 55% (antifreeze protection
down to –45 °C), since the heat is then
not dissipated as effectively.
If the vehicle has lost coolant, top it up with
equal parts of water and an antifreeze and
corrosion inhibitor. Mercedes-Benz recom-
mends that you use an antifreeze and cor-
rosion inhibitor which has been approved
for Mercedes-Benz.
! The co oling system has a permanent supply
which must be renewed after 15 years or
250,000 km at the most.
Merc edes-Be nzrecommends that you use an an-
tifreeze and cor rosion inhibitor which has been
appr oved for Mercedes-Benz. Over a period of time, the brake fluid ab-
sorbs moisture from the air; this reduces
its boiling point.
i
There is usually a notice in the engine com-
partment to remind you when the next brakeflu-
id change is due. The windscreen washer reservoir holds
approximately
3litres on all models with
aw indscreen washe rsystem. On models
with a heated windscreen washer fluid res-
ervoir ora headlamp cleaning system*, the
re servoir holds 6litres.
The head lamp cleaning system* and the
windscreen washer system have a com-
mon supply from the windscreen washer
fl uid reservoir.
6 Fill the windscreen washer fluid reser-
voirwith a solution of water and wind-
screen washer concentrate. Adapt the
mix ing ratio to sui tthe outsi detemper-
atures.
The windscreen wipers leave no marks.
The headlamp cleaning system and the
windscreen washer system do not
freeze. Brake fluid
G
Riskofaccident If the boiling
point of the brake fluid is too
low, vapour pockets may fo rmin the brake
system when the brak esare applied hard
(e.g. when driving dow nhill). This would im-
pair braki ngefficiency.
