effect, the driv
ewheels coul dlose their grip.
This inc reases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface.
Downhill gradients Do not depress the brake pedal continuously
while the vehicle is in motion ,e.g. causing the
brakes to rub by constantly applying light
pressure to the pedal. This results in exces-
sive and premature wear to the brake pads.
On long and steep downhil lgradients, you
mus tselect shift range 1,2or 3in good time.
Take particular not eofthis when drivin ga
laden vehicle.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC PLUS.
This will use the brakin geffect of the engine,
so les sbraking wil lberequired to prevent the
vehicle from gainin gspeed. This relieves the
load on the brak esystem and prevents the
brakes from overheating and wearing too
quickly.
Heavy and light loads G
WARNING
The braking syste mcan overheat if you leave
your foot on the brake pedal while driving.
This increases the braking distance and could
even cause the braking system to fail. There
is ar isk of an accident.
Never use the brake pedal as afootrest .Do
not simultaneousl ydepress both th ebrake
peda land the accelerato rpedal while driving.
! Depressing the brak epedal constantly
result sinexcessive and premature wear to
the brake pads.
If the brakes have bee nsubjected to aheavy
load, do not stop the vehicle immediately.
Driv eonfor as hort while. This allow sthe air-
flo wtoc ool the brakes mor equickly. If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet road surfaces
If you have driven for
along tim einheavy rain
without braking ,there ma ybeadelayed reac-
tion from the brakes when braking for the first
time. This may also occu rafter acar wash or
after driving through deep water.
You then have to depress the brake pedal
more firmly. Maintain agreater distance from
th ev ehicle in front.
Af terd riving on awet road or havin gthe vehi-
cle washed, brake firml ywhile paying atten-
tion to the traf ficc onditions. This will warm
up the brake discs, thereby dryin gthem more
quickly and protecting them against corro-
sion.
Limited braking performanc eonsalt-
treated roads If you drive on salte
droads, alaye rofs alt
residue may form on the brake discs and
brake pads. This can result in asignificantly
longer brakin gdistance.
R Brake occasionally to remov eany possible
salt residue. Make sure that you do not
endanger other road users whe ndoing so.
R Carefully depress the brake pedal and the
beginning and end of ajourney.
R Maintain agreater distance to th evehicle
ahead.
New brak epads/linings New and replace
dbrake pads and discs only
reach thei roptimum braking effect after sev-
eral hundred kilometres of driving. Compen-
sate for this by applying greater force to the
brak epedal.

mends that you only have brak epads/linings

drive at aconstan tspeed (e.g. heavy tra ffic
or winding roads). You may otherwise
cause an accident.

General notes Cruis

speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhil lgradients, especiall yifthe
vehicle is laden or towing atrailer, yo umust
select shift range 1,2or 3in good time. By doing so, you will make use of the braking
effec
tofthe engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
Use cruise con trolonly if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan

Important safety notes G
WARNING
Never depress the brake peda lcontinuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the brakin gdistance
and can lead to the brakes failing completely. G
WARNING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G

If there is achange of drivers, advise the new
driver of the limit speed stored.
Only use variable SPE EDTRONI Cifyou will not
have to accelerate suddenl ytoaspeed above
that stored as the limit speed. You could oth-
erwise cause an accident.
You can only exceed the limit speed stored if
you deactivate variable SPE EDTRONIC:

General notes SPE
EDTRONIC brakes automatically so that
you do not exceed the set speed. On long and
steep downhil lgradients ,especially if the
vehicle is laden or towing atrailer, yo umust
select shift range 1,2or 3in good time. By
doing so, you will make use of the braking

sthe brakes
from overheating and wearing too quickly .If
you need additional braking, depres sthe
brake pedal repeatedly rather than con tinu-
ously.
You can set avariable or permanent limit
speed:
R variable for speedlimits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when drivin gwith winter tyres
