2015 MERCEDES-BENZ E-CLASS CABRIOLET tyre pressure

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. 160
Driving
tipsDriving an d 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 225).
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. 168

DISTRONIC PLUS Steering Assist does not pro-
vide assistance:
R on very sharp corners
R if a loss of tyre pressure or a defective tyre has
been detected and displayed
Pay attention also to the important safety notes
for DISTRONIC PLUS (Y page 168).
The steering interventions are carried out with a limited steering moment. The 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 steering wheel for a prolonged
period of time, the system will first alert you with a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold
of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you to take control of the vehicle. Steering Assist
and Stop&Go Pilot switch to passive mode.
DISTRONIC PLUS remains active.

General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep slopes
R when manoeuvring on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is cancelled and the HOLD
function is deactivated when you depress the
accelerator pedal to pull away.
Important safety notes G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply
R the HOLD function is deactivated by the
accelerator pedal being depressed, e.g. by
a vehicle occupant
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R the battery is disconnected
There is a risk of an accident.
Before leaving the vehicle, always deactivate
the HOLD function and secure the vehicle
from rolling away. Driving systems

R
snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 181) warning messages during the
parking procedure.
R you can intervene in the steering procedure to
correct it at any time. Active Parking Assist
will then be cancelled.
R when transporting a load which protrudes
from your vehicle, you should not use Active
Parking Assist.
R never use Active Parking Assist when snow
chains are fitted.
R make sure that the tyre pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends.
R on the same level as the road, e.g. not on the
pavement.
Detecting parking spaces Objects located above the height range of Active
Parking Assist will not be detected when the
parking space is measured. These are not taken into account when the parking procedure is cal-culated, e.g. overhanging loads, tail sections or
loading ramps of goods vehicles. G
WARNING
If there are objects above the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in front of these
objects
This could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection range
(Y page 180). Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction of
travel if:
R two parking spaces are located directly next
to one another
R the parking space is directly next to a low
obstacle such as a low kerb
R you forward park
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
to the direction of travel if:
R the parking space is on a kerb
R the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer Example: detected parking space

Active Parking Assist is activated automatically
when driving forwards. The system is opera-
tional at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel and
are at least 1.5 m wide
R that are parallel to the direction of travel and
at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your vehi-
cle

The yellow indicator lamp goes out if reverse
gear is engaged. Active Blind Spot Assist is not
operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Visual and acoustic collision warning
If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision
warning. You then hear a double warning tone
and red warning lamp :flashes. If the turn sig-
nal remains on, detected vehicles are indicated
by the flashing of red warning lamp :. There are
no further warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a side
impact in the monitoring range, a course-cor-
recting brake application is carried out. This is
designed to help you avoid a collision. G
WARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the sides. If a course-correcting brake application occurs,
red warning lamp :flashes in the exterior mir-
ror and a dual warning tone sounds. In addition, display ;underlining the danger of a side col-
lision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time if you steer slightly in the opposite
direction or accelerate. The course-correcting brake application is avail-
able in the speed range between 30 km/h and
200 km/h.
Either a course-correcting brake application
appropriate to the driving situation, or none at
all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, on both sides of your vehicle
R a vehicle approaches too closely on the side
R you have adopted a sporty driving style with
high cornering speeds
R you clearly brake or accelerate
R a driving safety system intervenes, such as
ESP ®
or PRE-SAFE ®

Lane-correcting brake application
G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation. G
WARNING
Active Lane Keeping Assist only detects traf-
fic conditions or road users to a limited
extent. In very rare cases, the system may
make an inappropriate brake application, e.g. after intentionally driving over a solid lane
marking. There is a risk of an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance to the side for
other traffic or obstacles. If you leave your lane under certain circumstan-
ces, the vehicle will brake briefly on one side.
This is intended to help you return the vehicle to
the original lane.
If a lane-correcting brake application occurs,
display :appears in the multifunction display.
A lane-correcting brake application can be made
after driving over a lane marking detected as
being solid or broken. Before this, a warning
must have been issued by means of intermittent
vibration through the steering wheel. In addi-
tion, a lane with lane markings on both sides
must be detected.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can have an influence on brake application: oncom- ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.
i A further lane-correcting brake application
can only occur after your vehicle has returned
to the original lane.
No lane-correcting brake application occurs if: R you clearly and actively steer, brake or accel-
erate
R you cut the corner on a sharp bend
R you have adopted a sporty driving style with
high cornering speeds or high rates of accel-
eration
R you have switched on the turn signal
R a driving safety system intervenes, such as
ESP ®
, PRE-SAFE ®
Brake or Active Blind Spot

R the transmission is not in position D
R on vehicles with a trailer tow hitch, the elec-
trical connection to the trailer has been cor-
rectly established
R an obstacle has been detected in the lane in
which you are driving
R a loss of tyre pressure or a defective tyre has
been detected and displayed
There is a possibility that the Active Lane Keep-
ing Assist could misjudge the given traffic sit-
uation. An inappropriate brake application may
be interrupted at any time if:
R you steer slightly in the opposite direction
R you switch on the turn signal
R you clearly brake or accelerate

You will find the applicable permissible values,
which must not be exceeded, in the vehicle
documents.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle under "Technical
data" (Y page 344).
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain a safe distance. Drive carefully.
When towing a trailer, always adjust your speed to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes The E 500 model cannot be used to tow a trailer.
i When towing a trailer, set the tyre pressure
on the rear axle of the towing vehicle for a
maximum load; see the tyre pressure table in
the fuel filler flap (Y page 324).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all.

i The height of the ball coupling changes with
the load of the vehicle. If necessary, use a
trailer with a height-adjustable drawbar.
You will find fitting dimensions and loads under "Technical data" (Y page 343). Driving tips i
Observe the notes on ESP ®
trailer stabilisa-
tion (Y page 68).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 344). If you utilise any of the
added maximum rear axle load when towing a
trailer, the vehicle/trailer combination may not
exceed a maximum speed of 100 km/h for rea-
sons concerning the operating permit. This also applies in countries in which the permissible
maximum speed for vehicle/trailer combina-
tions is above 100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to
when driving without a trailer and it will con-
sume more fuel.
Change into a lower gear in good time on long
and steep downhill gradients.
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. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
