Transfer case
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
!Performancet ests may only be carried out
on a2 -axle dynamometer. The brake system
or transfer case could otherwise be damaged. Contact aqualified specialist workshop for a
performancet est.
!Since ESP®engages automatically, the igni-
tion must be switched off (the SmartKey or
Start/Stop button must be in position 0or 1)
if:
Rthe electric parking brake is being tested
on abrake dynamometer
Rthe vehicle is being towed with only one
axle raised (not permitted for vehicles with
4MATIC).
The brake system could otherwise be dam-
aged.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as doing so will damage the transmission.

Electric parking brake
General notes
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, alwayst ake the
SmartKey with you and lock the vehicle. Never

The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there isamalfunction in
the system, it may not be possible to apply the
released parking brake.
XIf this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away.
XShift the automatic transmission to position
P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is amalfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake performs afunction
test at regular intervals while the engine is
switched off. The sounds that can be heard while
this is occurringa re normal.
Applying or releasing manually
XTo apply:push handle :.
When the electric parking brake is applied,
the red F(USA only) or !(Canada
only) indicator lamp lights up in the instru-
ment cluster.
The electric parking brake can also be applied
when the SmartKey is removed.
XTo release: pull handle:.
The red F(USA only) or !(Canada
only) indicator lamp in the instrument cluster
goes out.
The electric parking brake can only be released:
Rwhen the SmartKey is in position 1or 2in the
ignition lock (Ypage 131) or
Rif the ignition was switched on using the
Start/Stop button
Applying automatically
The electric parking brake is automatically
applied when the transmission is in position P
and:
Rthe engine is switched off or
Rthe driver is not wearing aseat belt and the
driver's door is opened
To prevent the electric parking brake from being automatically applied, pull handle :.
The electric parking brake is also engaged auto-
matically if:
RDISTRONIC PLUS brings the vehicle to a
standstill or
Rthe HOLD function is keeping the vehicle sta- tionary
RActive Parking Assist is keeping the vehicle
stationary
In addition, at least one of the following condi-
tions must be fulfilled:
Rthe engine is switched off
Rthe driver is not wearing aseat belt and the
driver's door is opened
Rthere is asystem malfunction
Rthe power supply is insufficient
Rthe vehicle is stationary for alengthy period
The red F(USA only) or !(Canada only)
indicator lamp in the instrument cluster goes
out.
The electric parking brake is not automatically
engaged if the engine is switched off by the ECO
start/sto pfunction.
Releasing automatically
Your vehicle's electric parking brake is auto-
matically released if all of the following condi-
tions are met:
Rthe seat belt has been fastened.
Rthe engine is running.
Ryou accelerate and the transmission is in
position Dor R.
or
you shift the transmission position from Pto
position Dor R.Y ou will need to accelerate
more on steeper gradients.
If the transmission is in position R,the trunk lid
must be closed.
154Parking
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.

The steerin ginterventions are carried out with a
limited steerin gmoment.T he system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steerin gwheel for aprolonged
period of time, the system will first alert you with
av isual warning. Asteerin gwheel symbol

General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away,e specially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
