ried out, this could result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as necessary repairs car-
ried out at a qualified specialist workshop. G
WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop. G
WARNING
Modifications to electronic components, their software as well as wiring could affect their
function and/or the operation of other net-
worked components. This could in particular
also be the case for systems relevant to
safety. They might not function properly any-
more and/or jeopardise the operational
safety of the vehicle. There is an increased
risk of an accident and injury.
Do not attempt to modify the wiring as well as
electronic components or their software.
Always have work on electrical and electronic components carried out at a qualified special-
ist workshop.
If you make any changes to the vehicle elec-
tronics, the general operating permit is ren-
dered invalid.
! There is a risk of damage to the vehicle if:
R the vehicle becomes stuck, e.g. on a high
kerb or an unpaved road
R you drive too fast over an obstacle, e.g. a
kerb or a pothole in the road
R a heavy object strikes the underbody or
parts of the chassis In situations like this, the body, the under-
body, chassis parts, wheels or tyres could
be damaged without the damage being visi-
ble. Components damaged in this way can
unexpectedly fail or, in the case of an acci-
dent, no longer withstand the strain they
are designed for.
If the underbody panelling is damaged,
combustible materials such as leaves,
grass or twigs can gather between the
underbody and the underbody panelling. If
these materials come in contact with hot
parts of the exhaust system, they can catch fire.
In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If, upon con-
tinuing your journey, you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
visit a qualified specialist workshop.
Hybrid vehicles have a combustion engine
and an electric motor. The voltage supply for
operating the vehicle electrically is provided
by the vehicle's high-voltage electrical sys-
tem. G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
The components of the vehicle's high-voltage
electrical system are marked with yellow 26
Introduction

warning stickers. The cables of the vehicle's
high-voltage electrical system are orange.
Vehicles with an electric motor generate sig-
nificantly less noise than vehicles with inter-
nal combustion engines. As a result, in certain situations your vehicle may not be heard by
other road users. This can happen, for exam-
ple, when you are parking and your vehicle is not seen by other road users. This requires
you to adopt a particularly anticipatory driving
style, as it is necessary to allow for the pos-
sibility that other road users may behave
unpredictably. Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the information
systems and communication devices integra-
ted into the vehicle which receive and/or
transmit radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant
with the basic requirements and all other rel- evant conditions of Directive 1999/5/E C.
You can obtain further information from any
Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi-
cle components has been checked and certi-fied according to the currently valid version of
Regulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at a qualified specialist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may affect the operating safety of the vehicle.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle.
G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats on top of one another.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring information being reset, for example. This
may lead to the vehicle failing to meet the
requirements of the next emissions test dur-
ing the main inspection. Qualified specialist workshop
A qualified specialist workshop has the nec-
essary special skills, tools and qualifications
to correctly carry out any necessary work on
your vehicle. This particularly applies to work
relevant to safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at a qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R modifications, installations and conver-
sions Introduction

Useful information
i This Owner's Manual describes all mod-
els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.
i Read the information on qualified special-
ist workshops: (Y page 27). Hybrid vehicles
General notes
Hybrid technology combines a fuel-efficient
internal combustion engine with a powerful
electric motor. Important safety notes
Danger of electric shock G
DANGER
The vehicle's high voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Do not touch any high-voltage components
after an accident and never modify the vehi-
cle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system
checked by a qualified specialist workshop. When towing a vehicle after an accident, be
sure to observe the following sections:
R Transporting the vehicle (Y page 427)
R Towing the vehicle with the rear axle raised
(Y page 426)
R Towing the vehicle with both axles on the
ground (Y page 427)
Read the safety instructions on towing and
tow-starting (Y page 424). All components of the hybrid system are
marked with yellow warning stickers that
warn you of the danger of high voltage. The
cables of the vehicle's high-voltage electrical
system are orange in colour.
The ignition must be switched off when car-
rying out general tasks, such as changing
bulbs or checking the coolant level.
Automatic deactivation of the hybrid
system G
DANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. In addition, the vehicle's high-voltage electri-
cal system may not be deactivated as inten-
ded in the event of an accident. Touching
damaged components of the vehicle's high-
voltage electrical system could result in an
electric shock. There is an increased risk of
injury, possibly even fatal. 42
Hybrid vehiclesSafety

The restraint system includes:
R seat belt system
R airbags
R child restraint system
R child seat securing systems
The components of the restraint system are
complementary. They can offer maximum
protection only when all vehicle occupants:
R secure their seat belts correctly
(Y page 48)
R adjust the seat and head restraints prop-
erly (Y page 119)
As the driver, you must also make sure that
the steering wheel is adjusted correctly.
Observe the information on the correct driv-
er's seat position (Y page 118).
Additionally, you must make sure that the air- bag can inflate without restriction if deployed
(Y page 51).
An airbag is supplementary to a correctly fas-
tened seatbelt. An airbag, as an additional
safety device, provides greater protection for vehicle occupants in an accident situation. If
the seat belts offer sufficient protection in the
event of an accident, for example, the airbags
will not be deployed. Also, only the airbags
which are deemed to offer protection in the
corresponding accident situation are
deployed. However, seat belts and airbags
generally do not protect against objects pen-
etrating the vehicle from the outside.
Information on how the restraint system
operates can be found in "Deployment of the seat belt tensioner and airbags"
(Y page 60).
See "Children in the vehicle" (Y page 63) for
further information on infants and children
travelling in the vehicle as well as on child
restraint systems. Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an airbag system
for a person with physical disabilities, contact a Mercedes-Benz Service Centre for details. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The 6 restraint system warning lamp in
the instrument cluster lights up when the igni- tion is switched on. It goes out no later than afew seconds after the vehicle is started. The
components of the restraint system are in
operational readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R does not light up after the ignition is
switched on
R does not go out after a few seconds with
the engine running
R lights up again while the engine is running
All vehicles, except hybrid vehicles: G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. Occupant safety

Important safety notes
If you fail to adapt your driving style or if you
are inattentive, the driving safety systems can
neither 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 the distance
to the vehicle in front, for vehicle speed and
for braking in good time. Always adapt your
driving style to suit the prevailing road,
weather and traffic 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
adequate 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 432).
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
effectively 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 allows you to continue steering the vehi- cle when braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched on. It goes out when the engine is running.
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 76). G
WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac- tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
If ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information on the ABS warning lamp (Y page 357) and
display messages which may be shown in the
instrument cluster (Y page 317).
ABS works from a speed of about
8 km/hupwards, regardless of road-surface
conditions. ABS works on slippery surfaces,
even when you only brake gently.
Braking X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force.
If ABS intervenes when braking, you will feel a pulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as a reminder to take extra care while
driving. BAS (Brake Assist)
General notes BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
