Once you have fitted the winter tyres:

Check the tyre pressures (Y page 186).
X Restart the tyre pressure loss warning sys-
tem (Y page 187). G
Risk of accident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving stability
will be impaired owing to unstable cornering
characteristics caused by the different tyres.
You should therefore adapty our driving style
and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use aMercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at aquali-
fied specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been speciallya pproved for your vehicle
by Mercedes-Benz,ora re ofacorresponding
standard of quality.
If you intend to fit snow chains, pleaseb ear
the following points in mind:
R you may not attach snow chains to all
wheel-tyre combinations; see the "Tyres
and wheels" section in the "Technical data"
chapter.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. a"Minispare"
emergency spare wheel.
R Fit snow chains only in pairs and only to the
rear wheels. Comply with the manufactur-
er's installation instructions.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling awayw ith snow chains fitted (Y
page 54). This way,y ou can allowthe
wheels to spin in acontrolled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine brak-
ing on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Vehicles with manual transmission: engage
neutral.
X Vehicles with automatic transmission*:
shift the selector lever to N.
X Try to bring the vehicle under control by
using corrective steering. Driving tips
Rolling with the engines
witchedoff G
Risk of accident
Never switch the engine off while the vehicle
is in motion.
There is no power assistance for the steering
and the service brake when the engine is not
running.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident. 190

Thi sw illu se the braking effect of the engine,
so less braking will be required to maintain
the speed .Thisr elieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. If yo uneed

Never depress the brake peda lcontinuously
whil ethe vehicl eisinmotion, e.g .neve rcause

In Germany, th emaximum permissible speed
for vehicle/trailer combinations depends on
th et ype of trailer and is either 80 km/h or
10 0k m/ h. In som ecountries ,higher maxi-
mum speeds are permissible for vehicle/
trailer combinations .Before beginnin gthe
journey, check th etrailer' sdocuments to see
what th emaximum permitted spee dis.
For certain Mercedes-Ben zvehicles, th emax-
imum permissible rear axle load is increased
when towing atrailer. Refer to th e"Technical
data" sectio ntofindo ut whether this applies
to your vehicle .Ifyou utilise any of th eadded
maximum rear axle load when towing atrailer,

When towing atrailer, your vehicle's handling

i This also applies if you have activated
cruise control, SPEEDTRONI CorDIS-
TRONIC PLUS*.
This will use th ebraking effect of th eengine,
so less braking will be required to maintain
