Driving and parking

When you take advantage of engine braking, a
drive 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-Benz war-
ranty.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stoppin gdistanc eand 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.
!Depressin gthe 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. Drive
on for ashort 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 reac-
tion 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.
Limited braking performance on salt-
treated roads
If you drive on salted roads, alayer of salt resi-
due may form on the brake discs and brake
pads. This can result in asignificantly longer
braking distance.
RIn order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
RCarefully depress the brake pedal and the
beginnin gand end of ajourney.
RMaintain agreater distanc etothe vehicle
ahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up in
the instrument cluster and
Ryou hear awarning ton ewhile the engine is
running
Observe additional 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. Consult aqualified specialist workshop to
arrange this.
!Vehicles with 4MATIC: function or per-
formance test smay only be carried out on a2-
axle dynamometer. If you wish to operate the
vehicle on such adynamometer, please con-
sult aqualified specialist workshop in
advance. You could otherwise damage the
drive train or the brake system.
!Vehicles with 4MATIC: the ESP®system
operates automatically. The engine and the
ignition must therefore be switched off (the
SmartKey must be in position 0or 1in the
ignition lock or the Start/Stop button must be
in position 0or 1)ift he electric parking brake
is tested on abrake dynamometer.
Brakin gtriggered automatically by ESP
®may
cause severe damage to the brake system.
All checksa nd maintenance work on the brake
system must be carried out at aqualified spe-
cialist workshop.
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 functional-
ity of your brakes at regular intervals.

158Driving tips
Driving and parking

For safety reasons, Mercedes-Benz recom-
mends only installing the following brake disks
and brake pads/linings:
Rbrake disks that havebeena pproved by
Mercedes-Benz
Rbrake pads/lining sthat hav ebeena pproved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake disks or brake pads/lining scan
compromise the safety of your vehicle.
Alway sreplace al lbrake disks and brake pads/
linings on an axl eatthe sam etime. Always
install new brake pads/lining swhenr eplacing
brake disks.
The vehicle is equipped with lightweight brake
disks to which the wheel assembly with rim and
threaded connectio nismatched.
The use of brake disks other than those
approved by Mercedes-Benz can chang ethe
track width and is subject to approval ,ifappli-
cable.
Shock-typ eloads whe nhandling the brake
discs, such as whe nchanging wheels ,can lead
to areduction in comfortw hend riving with light-
weigh tbrake discs. Avoid shock-type loads on
the lightweight brake disks, particularly on the
brake plate.
Mercedes-Benz recommends that yo uonly use
brake fluid that has bee nspeciall yapproved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard .Brake
fluid which has not bee napproved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
High-performance and ceramic brakes
(Mercedes AMG vehicles)
The AMG brake systems are designe dfor heavy
loads. Thism ay leadtonoisew henb raking. This
will depend on:
RSpeed
RBraking force
REnvironmental conditions, such as tempera-
ture and humidity
The wear of individua lcomponents of the brake
system, such as the brake pads/lining sorbrake
discs, depends on the individua ldriving style
and operating conditions.
For this reason, it is impossible to state amile-
ag ethat will be valid under al lcircumstances. An aggressive driving styl
ewilll ea dtoh ighw ear.
You can obtain more information on this from a
qualified specialist workshop.
New and replaced brake pads and discs only
reach thei roptimum braking effect afte rseveral
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
Kee pthis in mind ,and adap tyou rd riving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingl yhighb rake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake statu smessages in the multifunction
display. Especiall yfor hig hperformance driving,
it is important to maintain and hav ethe brake
system checked regularly.

Hydroplaning
If water has accumulated to acertain depth on
the roads urface,there is adanger of hydro-
planing occurring, even if:
Ryo ud rive at low speeds.
Rthe tires hav eadequate treadd epth.
For this reason, in the event of heavy rai norin
conditions in which hydroplaning may occur,
yo um ustd rive in the following manner:
Rlower your speed.
Ravoid ruts.
Ravoid sudden steering movements.
Rbrake carefully.

!Bearinm ind that vehicles traveling in front
or in the opposite directio ncreate waves. This
may cause the maximum permissibl ewater

Failure to observe these notes may result in
