ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the key
with you and lock the vehicle. Never leave
children unattended in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or the system is malfunc-
tioning, it may not be possible to apply the
released parking brake.
X If this is the case, park the vehicle only on
level ground and secure it to prevent it from
rolling away.
X Shift 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 if there is a malfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake carries out a function
check at regular intervals when the engine is
switched off. Noises that occur are normal. Applying or releasing manually X

sage appears
R the red !indicator lamp on the instrument
cluster flashes
When the vehicle has been braked to a stand-
still, the electric parking brake is applied. Parking up the vehicle
General notes If you leave the vehicle parked up for longer than
four weeks, the battery may be damaged by
exhaustive discharging.
If you leave the vehicle parked up for longer than
six weeks, it may suffer from lack of use.
X Contact a qualified specialist workshop and
seek advice.
i You can obtain information about trickle
chargers from a qualified specialist work-
shop.
Charge retention of the on-board elec-
trical system battery The battery may drain if the vehicle is left sta-
tionary for long periods. In this case, Mercedes- Benz recommends attaching the trickle charger
to the 12 V socket in the luggage compartment. A trickle charger can be obtained from a
Mercedes-Benz Service Centre, for example.
X Switch the ignition off.
X Open the tailgate. 122

Wet road surfaces
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after a car wash or
after driving through deep water.
You will have to depress the brake pedal more
firmly. Maintain a greater distance to the vehicle in front.
After driving on a wet 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 salt-treated roads, a layer of salt
may form on the brake discs and pads. This can
increase the braking distance considerably.
Observe the following rules when driving on salt- treated roads:
R in order to prevent any salt build-up, apply the
brakes occasionally while paying attention to
the traffic conditions.
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey.
R maintain a much greater distance to the vehi-
cle in front.
New brake discs and brake pads/
linings Brake pads/linings and discs that are either new
or have been replaced only achieve optimum
braking effect after several hundred kilometres
of driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal.
For safety reasons, Mercedes-Benz recom-
mends only fitting the following brake discs and
brake pads/linings:
R brake discs that have been approved by
Mercedes-Benz
R brake pads/linings that have been approved
by Mercedes-Benz or that are of an equivalent
standard of quality
Other brake discs or brake pads/linings can
compromise the safety of your vehicle. Always replace all brake discs and brake pads/
linings on an axle at the same time. Always fit
new brake pads/linings when replacing brake
discs.
The vehicle is equipped with lightweight brake
discs to which the wheel assembly with rim and threaded connection is matched.
The use of brake discs other than those
approved by Mercedes-Benz may alter track
width and is subject to approval, if applicable.
Shock-type loads when handling the brake
discs, such as when changing wheels, can lead
to a reduction in comfort when driving with light-
weight brake discs. Avoid shock-type loads on
the lightweight brake discs, particularly on the
brake plate.
AMG high-performance and ceramic
brakes The AMG brake systems are designed for heavy
loads. This may lead to noise when braking. This
is dependent on:
R speed
R braking force
R environmental conditions, such as tempera-
ture and humidity
The wear of individual brake system compo-
nents such as the brake pads/linings or brake
discs depends on individual driving style and
operating conditions.
For this reason, it is impossible to state a mile-
age (service life) that will be valid under all cir-
cumstances. An aggressive driving style will
lead to high wear. You can obtain more infor-
mation on this from a qualified specialist work-
shop.
Brake pads/linings and discs that are either new or have been replaced only achieve optimum
braking effect after several hundred kilometres
of driving. Compensate for the reduced braking
effect by applying greater force to the brake
pedal. Always be aware of this and adapt your
driving and braking accordingly during the run-
ning-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake wear
warning lamp in the instrument cluster and note
any brake status messages in the multifunction
display. If you regularly drive at high speeds, it is particularly important to have the brake system
checked and maintained regularly. 124

R drive at less than the stored speed without
kickdown
R set a new speed or
R call up the last speed stored again

SPEEDTRONIC passive message in the
multifunction display disappears.
Deactivating variable SPEEDTRONIC
It is not possible to deactivate variable SPEED-
TRONIC by braking. There are several ways to deactivate variable
SPEEDTRONIC:
X Briefly press the cruise control lever forwards
=.
or
X Briefly press the cruise control lever in the
direction of arrow ;.
LIM indicator lamp :in the cruise control
lever goes out. Variable SPEEDTRONIC is
deactivated.
Cruise control or DISTRONIC PLUS is selec-
ted.
i The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC You can use the on-board computer to perma-
nently limit the speed to a value between
160 km/h(e.g. for driving on winter tyres) and
the maximum speed (Y page 166).
Shortly before the stored speed is reached, it
appears in the multifunction display.
Permanent SPEEDTRONIC remains active even
if variable SPEEDTRONIC is deactivated. You cannot exceed the stored limit speed, even
if you depress the accelerator pedal beyond the
pressure point (kickdown). DISTRONIC PLUS
General notes DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance to the vehicle detected in front. Vehicles are detected
with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Shift to a lower gear in good time on long and
steep downhill gradients. Take particular note of
this when driving a laden vehicle. By doing so,
you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
If DISTRONIC PLUS detects a risk of collision
with the vehicle in front, you will be warned vis-
ually and acoustically. Without your interven-
tion, DISTRONIC PLUS cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately to increase the distance to the vehicle in front,
or take evasive action, provided it is safe to do
so.
DISTRONIC PLUS operates in the range
between 0 km/h and 200 km/h.
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
Important safety notes G
WARNING
DISTRONIC PLUS does not react to:
R people or animals
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
As a result, DISTRONIC PLUS may neither give
warnings nor intervene in such situations.
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. 130

puter (Y page 163).
The following information is displayed:
R the length of the journey since the last break
R the attention level determined by ATTENTION
ASSIST ( Attention level
Attention level), displayed as a
bar display with five levels from high to low
R if ATTENTION ASSIST is unable to calculate
the attention level and cannot issue a warn-
ing, the System suspended System suspended message
appears. The bar display then changes what is shown, e.g. if you are driving at a speed below
60 km/h or above 200 km/h
Activating ATTENTION ASSIST X
Activate ATTENTION ASSIST using the on-
board computer (Y page 165).
The system determines the attention level of
the driver depending on the setting selected:
If Standard
Standard is selected: the sensitivity with
which the system determines the attention level
is set to normal.
If Sensitive
Sensitive is selected: the sensitivity is set
higher. The attention level detected by ATTEN-
TION ASSIST is adapted accordingly and the
driver is warned earlier.
When ATTENTION ASSIST is deactivated, the
é symbol appears on the multifunction dis-
play on the assistant display when the engine is running.
When ATTENTION ASSIST has been deactivated, it is automatically reactivated after the engine
has been switched off. The sensitivity selected corresponds to the last selection activated
(standard/sensitive).
Warning on the multifunction display If fatigue or increasing lapses in concentration
are detected, a warning appears on the multi-
function display:

In addition to the message shown on the multi-
function display, you will then hear a warning
tone.
X If necessary, take a break.
X Confirm the message by pressing the a
button on the steering wheel.
On long journeys, take regular breaks in good
time to allow yourself to rest. If you do not take a break and ATTENTION ASSIST still detects
increasing lapses in concentration, you will be
warned again after 15 minutes at the earliest.
This will happen only if ATTENTION ASSIST still
detects typical indicators of fatigue or increas-
ing lapses in concentration.
If a warning is output in the multifunction dis-
play, a service station search is performed in
COMAND Online. You can select a service sta-
tion and you will then be navigated to this ser-
vice station. This function can be activated and
deactivated in COMAND Online. Traffic Sign Assist
