2015 MERCEDES-BENZ E-CLASS COUPE parking brake

ECO display assists you in achieving the most
economical driving style for the selected set-
tings and prevailing conditions. Consumption
can be significantly influenced by your driving
style.
The ECO display consists of three bars:
R Acceleration Acceleration
R Constant
Constant
R Coasting
Coasting
The percentage count is the mean value of the
three bar values. The three bars and the mean
value begin at the value of 50%. A higher per-
centage count indicates a more economical
driving style.
The ECO display does not indicate the actual fuel
consumption. A fixed percentage count in the
ECO display does not indicate a fixed consump- tion.
In addition to driving style, the consumption is
affected by many other factors, such as:
R load
R tyre pressure
R cold start
R choice of route
R the use of electrical consumers
These factors are not included in the ECO dis-
play.
The evaluation of your driving style takes the
following three categories into consideration:
R Acceleration
Acceleration (evaluation of all acceleration
processes):
- the bar fills up: moderate acceleration,
especially at higher speeds
- the bar empties: sporty acceleration
R Constant
Constant (assessment of driving behaviour
at all times):
- the bar fills up: constant speed and avoid-
ance of unnecessary acceleration and
deceleration
- the bar empties: fluctuations in speed
R Coasting Coasting (assessment of all deceleration
processes):
- the bar fills up: anticipatory driving, keep-
ing your distance and early release of the
accelerator. The vehicle can coast without
use of the brakes.
- the bar empties: frequent braking
i An economical driving style involves driving
at a moderate engine speed. To achieve a higher value in the categories
Acceleration Acceleration andConstant
Constant:
R observe the gearshift recommendation
R drive the vehicle in drive program E(vehi-
cles with automatic transmission)
i On long journeys at a constant speed, e.g.
on the motorway, only the bar for Constant
Constant
will change.
i The ECO display summarises the driving
characteristics from the start of the journey to
its completion. Therefore, there are dynamic
changes in the bars at the start of a journey.
During a prolonged driving time, these
changes are smaller. For more dynamic
changes, perform a manual reset.

Important safety notes G
WARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
This increases the risk of skidding and having
an accident.
Do not shift down for additional engine brak-
ing on a slippery road surface.
Downhill gradients Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by constantly applying light
pressure to the pedal. This results in excessive
and premature wear to the brake pads.
Change into a lower gear in good time on long
and steep downhill gradients.
Take particular note of this when driving a laden vehicle and when towing a trailer.
i This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine, so
less braking will be required to maintain vehicle
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. Driving

Heavy and light loads
G
WARNING
The braking system can 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
a risk of an accident.
Never use the brake pedal as a footrest. Do
not simultaneously depress both the brake
pedal and the accelerator pedal while driving.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the airflow
to cool the brakes more quickly.
If the brakes have been used only moderately,
you should occasionally test their effectiveness.
To do this, brake more firmly from a higher
speed while paying attention to the traffic con-
ditions. This improves the grip of the brakes.
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. 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 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 that you only have brake pads/linings
fitted to your vehicle which have been approved
for Mercedes-Benz vehicles or which corre-
spond 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. Driving on wet roads
Aquaplaning If water has accumulated to a certain depth on
the road surface, there is a danger of aquaplan-
ing occurring, even if:
R you are driving at low speeds
R the tyres have adequate tread depth
For this reason, drive in the following manner in the event of heavy rain or in conditions in which
aquaplaning can occur:
R lower your speed
R avoid tyre ruts
R avoid sudden steering movements
R brake carefully
Driving on flooded roads !
Bear in mind that vehicles travelling in front
or in the opposite direction create waves. This may cause the maximum permissible water
depth to be exceeded. 154
Driving tipsDriving and parking

Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. You must select a low
gear in good time on long and steep downhill
gradients, especially if the vehicle is laden or
towing a trailer. By doing so, you will make use of
the braking effect of the engine. This relieves the load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady speed for a prolonged period. You can store any
road speed above 30 km/h.
Important safety notes If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account road, weather or traffic
conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time
and for staying in lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored. Cruise control lever :

R you are driving faster than 30 km/h.
R ESP ®
must be switched on, but not interven-
ing.
R the transmission must be in position D.

driving faster than 30 km/h.
X Accelerate the vehicle to the desired speed.
X Briefly press the cruise control lever up :or
down ;.
X Remove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by auto-
matically braking the vehicle. i
Vehicles with manual transmission:
R always drive at adequate, but not exces-
sive, engine speeds
R change gear in good time.
R if possible, do not change down several
gears at a time
Storing the current speed or calling up
the last stored speed G
WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you do not know the stored speed, store the
desired speed again. X
Briefly pull the cruise control lever towards
you :.
X Remove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously stored
speed. Driving systems

The last stored speed increases or decreases in 10 km/h increments.
i Cruise control is not deactivated if you
depress the accelerator pedal. For example, if
you accelerate briefly to overtake, cruise con-
trol adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control There are several ways to deactivate cruise con-
trol:
X Briefly press the cruise control lever for-
wards :.
or X Brake.
or X Briefly press the cruise control lever in the
direction of arrow =.

R on vehicles with manual transmission, you
shift into neutral while driving or depress the
clutch pedal for longer than six seconds
R on vehicles with manual transmission, you
shift to a gear that is too high, and as a result
the engine speed is too low
R on vehicles with automatic transmission, you
shift to position Nwhile driving
If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise con‐ Cruise con‐
trol off
trol off message in the multifunction display
for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
Important safety notes SPEEDTRONIC brakes automatically so that you
do not exceed the set speed. Change into a
lower gear in good time on long and steep down-
hill 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 system and
prevents the brakes from overheating and wear- ing too quickly. If you need additional braking,
depress the brake pedal repeatedly rather than continuously.
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an acci-
dent nor override the laws of physics. SPEED-
TRONIC cannot take into account road, weather 158
Driving systemsDriving and parking

i
The last speed stored is cleared when you
switch off the engine.
Permanent SPEEDTRONIC You can use the on-board computer to limit the
speed permanently to a value between
160 km/h( e.g. for driving on winter tyres) and
the maximum speed (Y page 218).
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.
Change into 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 system and prevents the brakes from overheat- ing and wearing too quickly.
If DISTRONIC PLUS detects that there is a risk of
a collision, you will be warned visually and
acoustically. Without your intervention,
DISTRONIC PLUS cannot prevent a collision. 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 driving in
front, or take evasive action, provided it is safe
to do so.
For DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
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. G
WARNING
DISTRONIC PLUS cannot always clearly rec-
ognise other road users and complex traffic
conditions.
In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be prepared to
brake, particularly if DISTRONIC PLUS warns
you. G
WARNING
DISTRONIC PLUS brakes your vehicle with up to 50% of the maximum possible deceleration.
If this deceleration is not sufficient,
DISTRONIC PLUS alerts you with a visual and
acoustic warning. There is a risk of an acci-
dent.
Apply the brakes yourself in these situations
and try to take evasive action.
! When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat- ically in certain situations. Driving systems

Activating DISTRONIC PLUS Activation conditions
To activate DISTRONIC PLUS, the following con-
ditions must be fulfilled:
R the engine must be running. It may take up to
two minutes of driving before DISTRONIC
PLUS is ready for use.
R the parking brake must be released.
R ESP ®
must be switched on, but not interven-
ing.
R Active Parking Assist must not be activated.
R the transmission must be in position D.
R the driver's door must be closed when you
shift from Pto Dor your seat belt must be
fastened.
R the front-passenger door must be closed.
R the vehicle must not be skidding.
R the DISTRONIC PLUS function must be selec-
ted with the cruise control lever (Y page 162).

you ;, or press it up :or down =.
DISTRONIC PLUS is activated.
X Press the cruise control lever repeatedly
up : or down =until the desired speed is
set.
X Remove your foot from the accelerator pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed. If the vehicle in front of you is stationary, you can
only activate DISTRONIC PLUS once your vehi-
cle is stationary as well.
i If you do not fully release the accelerator
pedal, the DISTRONIC
DISTRONIC PLUS PLUSsuspended
suspended mes-
sage appears in the multifunction display. The
set distance to a slower-moving vehicle in
front will then not be maintained. You will be
driving at the speed you determine by the
position of the accelerator pedal.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is
30 km/h.
X Briefly pull the cruise control lever towards
you ;, up :or down =.
DISTRONIC PLUS is activated.
Activating at the current speed/last
stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again. X
Briefly pull the cruise control lever towards
you :.
X Remove your foot from the accelerator pedal.
DISTRONIC PLUS is activated. The first time it
is activated, the current speed is stored. Oth-
erwise, it sets the vehicle cruise speed to the
previously stored value. Driving systems

Driving with DISTRONIC PLUS
Pulling away and driving
X
If you want to pull away with DISTRONIC
PLUS:
remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you :.
or X Accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front.
If no vehicle is detected in front, your vehicle accelerates to the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ- ent line from another vehicle. The vehicle then
brakes automatically.
If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style when you select the Sor Mdrive program
(Y page 143). Acceleration behind the vehicle in
front or to the set speed is then noticeably more dynamic. If you have selected the Edrive pro-
gram, the vehicle accelerates more gently. This
setting is recommended in stop-start traffic. Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving faster than 70 km/h
R DISTRONIC PLUS is maintaining the distance
to a vehicle in front
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle is accel- erated. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
i Vehicles with COMAND Online:
when you
change lanes, DISTRONIC PLUS monitors the right lane in the case of left-side traffic or the
left lane in the case of right-side traffic.
Vehicles with Audio 20: when you change
lanes, DISTRONIC PLUS monitors the left lane
on left-hand-drive vehicles or the right lane on right-hand-drive vehicles.
Vehicles with COMAND Online Example: roundabout
i
The following function is not operational in
all countries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt to certain traffic situations. This is the case if,
while following a vehicle, DISTRONIC PLUS is
active and you:
R approach or drive around a roundabout
R approach a T-junction
R turn off at a motorway exit
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporarily maintains
the current driving speed and does not acceler- 164
