Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
Our objectives are to use the natural resour-
ces which form the basis of our existence on
this planet sparingly and in a manner which
takes the requirements of both nature and
humanity into consideration.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Energy consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating conditions of your vehicle
R your personal driving style
You can influence both factors. Therefore,
please bear the following in mind:
Operating conditions:
R observe the correct tyre pressure.
R do not carry any unnecessary weight in the
vehicle
R remove the roof rack once you no longer
need it.
R a regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R all maintenance work should be carried out
at a qualified specialist workshop.
Personal driving style:
R drive carefully and maintain a safe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking.
R monitor the vehicle's energy consumption. H
Environmental note
Have defective high-voltage batteries dis-
posed of in an environmentally responsible
manner. Consult a qualified specialist work- shop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benz recommends that
you use a Mercedes-Benz Service Centre for
this purpose.
Returning an end-of-life vehicle
EU countries only:
Mercedes-Benz will take back your old vehicle to dispose of it in an environmentally-responsible
manner in accordance with the European Union
(EU) End of Life Vehicles Directive.
There is a network of return points and disas-
sembly plants available. You can return your
vehicle to these plants free of charge. This
makes a valuable contribution to the recycling
process and the conservation of resources.
For further information on recycling old vehi-
cles, recovery and the terms of the policy, visit
the Mercedes-Benz homepage. Genuine Mercedes-Benz parts
H
Environmental note
Daimler AG also supplies reconditioned
assemblies and parts which are of the same
quality as new parts. For these, the same war-
ranty applies as for new parts.
! Airbags and seat belt tensioners, as well as
control units and sensors for these restraint
systems, may be installed in the following
areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R dashboard
R instrument cluster
R centre console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out repairs
or welding. You could impair the operating
efficiency of the restraint systems.
Have accessories retrofitted at a qualified
specialist workshop. Introduction

possible using the switches in the driver's
door. If indicator lamp ;is off, operation is

partment. Pets in the vehicle
G
WARNING
If you leave animals unsupervised or unse-
cured in the vehicle, they may push a button
or a switch, for example.
They could:
R activate vehicle equipment and become
trapped, for example
R switch vehicle systems on or off, thus
endangering other road users
In the event of an accident, sudden braking or
abrupt changes of direction, unsecured ani-
mals could be flung around the vehicle, injur-
ing the vehicle occupants. There is a risk of an accident and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals correctly during a
journey, e.g. in an animal transport box. Driving safety systems
Driving safety systems overview
In this section, you will find information about
the following driving safety systems:
R ABS (A nti-lock Braking System)
(Y page 61)
R BAS (Brake AssistSystem) (Y page 62)
R COLLISION PREVENTION ASSIST PLUS
(Y page 62)
R Adaptive brake lights (Y page 65)
R ESP ®
(Electronic StabilityProgram)
(Y page 65)
R EBD (e lectronic brake force distribution)
(Y page 66)
R ADAPTIVE BRAKE (Y page 67)
R STEER CONTROL (Y page 67) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override
the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance
from the vehicle in front. Drive carefully.
The driving safety systems described only work as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Please pay special attention to the
notes on tyres, recommended minimum tyre
tread depths etc. (Y page 266).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. ABS (Anti-lock Braking System)
General notes ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This Driving safety systems
61Safety Z

Observe the information on warning lamps
(Y page 218) and display messages which may
be shown in the instrument cluster
(Y page 190).
Only use wheels with the recommended tyre
sizes. Only then will ESP ®
function properly.
Characteristics of ESP ®Characteristics of ESP
®
If the ÷ ESP warning lamp goes out before
beginning the journey, ESP ®
is automatically
active.
If ESP ®
intervenes, the ÷ESP®
warning lamp
flashes in the instrument cluster.
If ESP ®
intervenes:
X Do not deactivate ESP ®
under any circum-
stances.
X When pulling away, only depress the acceler-
ator pedal as far as is necessary.
X Adapt your driving style to suit the prevailing
road and weather conditions.
Deactivating/activating ESP ®Important safety notes
You can select between the following statuses
of ESP ®
:
R ESP ®
is activated
R ESP ®
is deactivated G
WARNING
If you deactivate ESP ®
, ESP ®
no longer sta-
bilises the vehicle. There is an increased risk
of skidding and an accident.
Only deactivate ESP ®
in the situations descri-
bed in the following.
It may be best to deactivate ESP ®
in the follow-
ing situations:
R when using snow chains
R in deep snow
R on sand or gravel
i Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®
will
otherwise not be able to stabilise the vehicle
if the vehicle starts to skid or a wheel starts to
spin. Deactivating/activating ESP
®
You can deactivate or activate ESP ®
via the on-
board computer (Y page 182).
ESP ®
deactivated:
The å ESP®
OFF warning lamp in the instru-
ment cluster lights up.
ESP ®
activated:
The å ESP®
OFF warning lamp in the instru-
ment cluster goes out.
Characteristics when ESP ®
is deactivated
If ESP ®
is deactivated and one or more wheels
start to spin, the ÷ESP®
warning lamp in the
instrument cluster flashes. In such situations,
ESP ®
will not stabilise the vehicle.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability
R Engine torque is no longer limited and the
drive wheels are able to spin
The spinning of the wheels results in a cutting
action for better traction on loose surfaces.
R Traction control is still activated
R COLLISION PREVENTION ASSIST is no longer
available; nor is it activated if you brake firmly
with assistance from ESP ®
R PRE-SAFE ®
is no longer available; it is also not
activated if you brake firmly with assistance
from ESP ®
R ESP ®
still provides support when you brake
firmly EBD (electronic brake force distribu-
tion)
General notes EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 61). G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the risk of skidding and an accident. 66
Driving safety systemsSafety

If, after the charging process, the charging cable
is:
R left connected to the power socket, the cur-
rently selected values will be used for the next
charging process.
R removed from the power socket, the values
will be reset to the minimum setting for the
next charging process. You may then need to reset the values of the maximum charge cur-
rent.
If the charge current values that have been set
on the charging cable and the on-board com-
puter are different, the high-voltage battery is
charged using the lower value.
If the vehicle requires more time than usual to
charge the high-voltage battery, check:
R the settings of the maximum charge current
on the controls of the charging cable
R the settings of the maximum charge current in
the menu of the on-board computer
