fuel consumption MERCEDES-BENZ B-CLASS HATCHBACK 2015 Owners Manual

Drive sensibly – save energy
Observe the following tips to save energy:
R The tyres should always be inflated to the rec-
ommended tyre pressure.
R Remove unnecessary loads.
R Remove roof racks when they are not needed.
R Avoid frequent acceleration or braking.
Energy consumption also increases when driv-
ing in low or high outside temperatures, in stop-
start traffic, on short journeys and in hilly ter-
rain. ECO display
The ECO display provides feedback on how eco-
nomical your driving characteristics are. The
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
To achieve a higher value in the categories
Acceleration Acceleration andConstant
Constant, drive the vehicle
in drive program E+orE.
On long journeys at a constant speed, e.g. on the motorway, only the bar for Constant
Constant will
change.
The ECO display summarises the driving char-
acteristics 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, per-
form a manual reset.

Important safety notes G
WARNING
If you increase the recuperation level on slip- pery road surfaces, the drive wheels may lose
their traction. This increases the risk of skid-
ding and having an accident.
Do not increase the recuperation level on slip-
pery road surfaces. 148
Driving tipsDriving and pa
rking

Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
X Place the ratchet ring spanner onto the hex-
agon nut of the jack so that the letters ABare
visible.
X Turn the ratchet ring spanner until the vehicle
is once again standing firmly on the ground.
X Place the jack to one side. X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated (: toA).
The specified tightening torque is 130 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the vehicle tools
in the vehicle again.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 269).
If you are driving with the emergency spare
wheel fitted, the tyre pressure monitor cannot
function reliably. Only restart the tyre pressure
monitor when the defective wheel has been
replaced with a new wheel. All fitted wheels
must be equipped with functioning sensors.
Vehicles with a tyre pressure monitor: all fit-
ted wheels must be equipped with functioning
sensors. Wheel and tyre combinations
General notes
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO = Mercedes-Benz Original
R MOE = Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from
any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected on
retreaded tyres. As a result, Mercedes-Benz
cannot guarantee vehicle safety if retreaded
tyres are fitted. Do not fit used tyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and therisk of damage to the wheels and tyres as a
result of driving over obstacles increases.
Overview of abbreviations used in the following tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
The recommended tyre pressures for various
operating conditions can be found in the tyre
pressure table on the charge socket flap. For
