In addition to driving style, the consumption
is affected by many other factors, such as:
R
Load
R Tire pressure
R Cold start
R Choice of route
R the use of electrical consumers
These factors are not included in the ECO
display.
The evaluationofy our driving style takes the
following three categories into consideration:
Acceleration (evaluation of all
acceleration processes) The bar fills up: The bar empties:
Moderate
acceleration,
especially at higher
speeds Sporty acceleration
Constant (assessment of driving
behavior at all times) The bar fills up: The bar empties:
Constant speed and
avoidance of
unnecessary
acceleration and
deceleration Fluctuations in
speed
Coasting (assessment of all deceleration
processes)
The bar fills up: The bar empties:
Anticipatory driving,
keeping your
distance and early
release of the
accelerator: the
vehicle can coast
without use of the
brakes Frequent braking i
An economical driving style involves
driving with a moderate engine speed.
To achieve a higher value in the categories
"acceleration" and "smooth driving":
R observe the gearshift recommendation.
R drive the vehicle in drive program E
(vehicles with automatic transmission).
i On long journeys at a constant speed, e.g.
on the freeway, only the bar for "smooth
driving" will change.
i The ECO display summarizes 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 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.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine
braking on a slippery road surface.
Downhill gradients !
On long, steep gradients, you must
reduce the load on the brakes. In order to
use engine braking effect, restrict the shift
range in good time. This helps you to avoid
overheating the brakes and wearing them
out excessively.
When making use of the engine braking
effect, it is possible that a drive wheel may
not turn for some time, e.g. in the case of
suddenly changing or slippery road surface 160

stored speed on downhill gradients by
automatically applying the brakes.
i Vehicles with manual transmission:
R Always drive at adequate, but not
excessive, engine speeds.
R Change gear in good time.
R If possible, do not shift down several
gears at a time.

adjustments.
Increase or decrease the set vehicle speed to
a value that the prevailing road conditions and
legal speed limits permit. Otherwise, sudden
and unexpected acceleration or deceleration
of the vehicle could cause an accident and/
or serious injury to you and others.
X To adjust the set speed in 1 mph
increments (1 km/h increments): briefly
press the cruise control lever up 0003to the pressure point for a higher speed or
down
0023for a lower speed.
Every time the cruise control lever is
pressed up or down, the last speed stored
is increased or reduced.

R the engine must be started. It may take up
to two minutes after pulling away before
DISTRONIC PLUS is operational.
R your vehicle must not be secured by the
electric parking brake.

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 has been detected and
is shown in the multifunction display, you can
also activate DISTRONIC PLUS when driving
at speeds below 20 mph (30km/h). If the
vehicle in front is no longer detected and
displayed, for example because it has
changed lanes, DISTRONIC PLUS is
deactivated. You will hear awarning tone if
this is the case.
i If you do no tfully release the accelerator
pedal, the DISTRONIC PLUS Override message appears in the multifunction

Pulling away and driving G
WARNING
When you step on the brake pedal, you switch
off the DISTRONIC PLUS except when the
vehicle is at a standstill. The DISTRONIC PLUS
will no longer brake your vehicle. You are
always responsible for maintaining a distance
fro mo thervehicles, observing road speeds
and braking well in advance. X
If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever toward
you 0024.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
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 fron thas slowed down, it brakes your
vehicle. It maintains the preset distance to
the vehicle in front.
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.
Changing lanes G
WARNING
DISTRONI CPLUS and Active Blind Spot Assist
are only aids designed to assist driving.
They do not relieve you of the responsibility
of paying attention. The driver remains fully
responsible for the vehicle's distance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and yours urroundings.
Otherwise, you may fail to recognize dangers
in time, cause an acciden tand injure yourself
and others.
If you wish to change to the passing lane (in
countries where traffic drives on the right, the
passing lane is the left-hand lane),

WARNING
Make sure that no persons or animals are in
the maneuvering range. Otherwise, they
could be injured.
! Pay particula rattention to low objects or
objects with flat surfaces ,such as trailer
drawbars, posts, cross beams and curbs.
These types of objects canno tbe detected
by Parking Guidance and may damage the
vehicle.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As uitable parking space is indicated by the
parking symbol. You receive steering
instructions when parking .You may also use
PARKTRONIC (Y page 178).
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat curbs
Parking tips:
R on narrow roads, drive past the parking
space as close as possible.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 179) warning messages during the
parking procedure. R
when transporting a load which protrudes
from your vehicle, you must not use Parking
Guidance.
R never use Parking Guidance with snow
chains or an emergency spare wheel
mounted.
R make sure that the tire pressures are
always correct. This has adirec teffect on
the steering instructions.
R the way you rvehicle is positioned in the
parking space after parkin gis dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. In some cases, Parking

enough into a parking space. In some
cases, it may also lead you across or onto
the curb. If necessary, cancel the parking
