Important safety notes G
WARNING
If you shift down on aslippery road surface in
an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on aslippery road surface.
Downhill gradients !
On long and steep gradients, you must
reduce the load on the brakes by shifting to
al ower gear in good time. This allows you
to take advantage of the engine's braking
effect. For this, you need to have selected
manual drive program M.This helps you to
avoid overheating the brakes and wearing
them out excessively.
When you take advantage of the engine's
braking effect,ad rive wheel may not turn
for some time, e.g. on aslippery road
surface. This could cause damage to the
drive train. This type of damage is not
covered by the Mercedes-Ben zwarranty.
i Briefl ydepressing th eaccelerato rpedal
on downhill gradient swhile the manual
drive program Mis temporarily activated:
the automatic transmission may switch to the last activ
eautomatic drive program E
or S.T he automatic transmission may shift
to ah igher gear. This can reduce the
engine's braking effect.
Heavy and light loads G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as afootrest .Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to aheavy
load, do not stop the vehicle immediately.
Driv eonf oras hort while. This allows the
airflow to cool the brakes more quickly.
Wet roads If you have driven for
along time in heavy rain
without braking ,there may be adelayed
reaction from the brakes when braking for the
first time. This may also occur after the
vehicle has been washed or driven through
deep water.
You have to depress the brake pedal more
firmly. Maintain agreater distanc efrom the
vehicle in front.
After driving on awet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions .This will
warm up the brake discs, thereby drying them
more quickly and protecting them against
corrosion.

treated roads If you drive on salted roads,

R Brak eoccasionally to remov eany possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R Carefully depress the brake pedal and the
beginning and end of ajourney.
R Maintain agreater distance to the vehicle
ahead.
Servicing the brakes !
If the red brake warning lamp lights up in
the instrument cluster and you hear a
warning ton ewhile the engin eisrunning,
the brake fluid level may be too low.
Observ eadditional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at aqualified specialist workshop.
! Afunction or performanc etest should
only be carried out on a2-axle
dynamometer. If yo uareplanning to have

contact an authorize dMercedes-Benz
Center to obtai nfurthe rinformatio nfirst.
Otherwise, yo ucould damage the drive

! As the ESP ®
system operates
automatically, the engine and the ignition
must be switched off (the SmartKe ymust
be in position 0or 1in the ignition lock) if:
R the electri cparking brak eistested on a
brake dynamometer (for amaximum of
ten seconds)
R the vehicle is towed with the front axle

Braking triggered automaticallybyE SP®
may seriouslyd amage the brake system.
All checks and maintenance work on the
brake system must be carried out at a qualified specialist workshop. Consult a
qualified specialist workshop to arrange this.
Have brake pads installed and brake fluid
replaced at
aqualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the
functionality of your brakes at regular
intervals.
You can find adescription of Brake Assist
(BAS) on (Y page 64).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your
vehicle which have been approved for
Mercedes-Benz vehicles or which correspond
to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality could affect your
vehicle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Checking brake liningt hickness You can measure the break pad/lining
thickness using
atest gauge.C olor-coding
(green or red) on the test gauge allows you to
determin ewhether the brake pad/lining
thickness is still sufficient .The test gauge is
