Downhil lgradients On long and stee

yo um usts hift to alower gearing oodtime or,
on vehicles with automatic transmission*,
select shift range 1,2or 3.
i Thisalsoa pplies if youhavea ctivated
cruis econtrol, SPEEDTRONIC or DIS-
TRONIC PLUS*.
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
additional braking ,depress the brake pedal
repeatedly rather tha ncontinuously.
Heavy and light loads If the brakes have been subjected to
aheavy
load ,don ot stop the vehicl eimmediately, but
drive on for ashort while. Thi sallow sthe air-
flo wtoc oolthe brakes more quickly. G
Ris
kofa ccident
Never depress the brake peda lcontinuously
whil ethe vehicl eisinmotion, e.g .neve rcause
the brakes to ru bbyapplyingconstant slight
peda lpressure. Thi scauses the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
If the brakes have been used onl ymoderately,

Wet roads If driving in heavy rain for

After driving on awetroa dorh aving the vehi-

brake discs will become warm, drying more
quickly, which will protect them against cor-

The laye rofsaltont he brake discs and the
brake pads/lining smaycause adelay in the

accident.
To avoid thi sdanger ,you should:

trailer stabi-
lisation (Y page 55).
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,
th ev ehicle/trailer combinatio nmay not
excee damaximum spee dof100km/h for
reason sconcernin gthe operatin gpermit. This also applies in countries in whic
hthe
permissible maximum spee dfor vehicle/
trailer combinations is abov e100 km/h. G

Always observ ethe maximum spee dpermit-
te dinG ermany for vehicle/traile rcombina-

are permitted. This lower sthe riskofana cci-
dent.
When towing atrailer, your vehicle's handling
characteristic swill be different in comparison
to when driving without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleratio nand gradi-
ent-climbin gcapability
R has an increased braking distance
R is affected mor ebystron gc rosswinds
R demands mor esensitive steering
R consumes mor efuel
On lon gand steep downhill gradients ,you
must selec talower gear in good time, or on
vehicle switha utomatic transmission*, select
shif trange 1,2or 3.
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
th es peed. This relieves th eload on th ebrake
system and prevents th ebrakes from over-
heating and wearin gtoo quickly. If you need
additional braking ,depress th ebrak epedal
repeatedly rather than continuously. G

Never depress th ebrak epedal continuously
while th evehicle is in motion ,e.g.n ever cause
th eb rakes to rub by applyin gconstant slight
