The original purchase contract documentation
for your vehicle contains a list of all the systems
in your vehicle.
Should you have any questions concerning
equipment and operation, please consult an
authorized Mercedes-Benz Center.

Introduction

Sports Utility Vehicle
G WARNING
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road
conditions. There is a risk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the
prevailing road and weather conditions.
Utility vehicles have a significantly higher roll-
over rate than other types of vehicles.
Failure to operate this vehicle safely may result
in an accident, rollover of the vehicle, and severe
or fatal injury.
In a rollover crash, an unbelted person is signif-
icantly more likely to die than a person wearing
a seat belt.
You and all vehicle occupants should always
wear your seat belts.
Operating safety
Important safety notes
G WARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried 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 can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
! There is a risk of damage to the vehicle if: R
the vehicle becomes stuck, e.g. on a high
curb or an unpaved road R
you drive too fast over an obstacle, e.g. a
curb, speed bumps 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 tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. 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 spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
Declarations of conformity
USA: "The wireless devices of this vehicle com-
ply with Part 15 of the FCC Rules. Operation is
subject to the two following two conditions: 1)28
Introduction

These devices may not cause harmful interfer-
ence, and 2) These devices must accept any
interference received, including interference
that may cause undesired operation. Changes
or modifications not expressly approved by the
party responsible for compliance could void the
user’s authority to operate the equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the fol-
lowing two conditions: (1) These devices may
not cause interference, and (2) These devices
must accept any interference, including inter-
ference that may cause undesired operation of
the device."
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 may affect the
operation of vehicle systems. As a result, the
operating safety of the vehicle could be affec-
ted. There is a risk of an accident.
Only connect equipment to a diagnostics con-
nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz.
G WARNING
Objects in the driver's footwell can restrict the
pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor- mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of
the next emissions test during the main inspec-
tion.
Qualified specialist workshop An authorized Mercedes-Benz Center is a quali-
fied specialist workshop. It has the necessary
specialist knowledge, tools and qualifications to
correctly carry out the work required on your
vehicle. This is especially the case for work rel-
evant to safety.
Observe the notes in the Maintenance Booklet.
Always have the following work carried out at an
authorized Mercedes-Benz Center: R
work relevant to safety R
service and maintenance work R
repair work R
alterations, installation work and modifica-
tions R
work on electronic components
Correct use If you remove any warning stickers, you or oth-
ers could fail to recognize certain dangers.
Leave warning stickers in position.
Observe the following information when driving
your vehicle: R
the safety notes in this manual R
the vehicle technical data R
traffic rules and regulations R
laws and safety standards pertaining to motor
vehicles
Problems with your vehicle If you should experience a problem with your
vehicle, particularly one that you believe may
affect its safe operation, we urge you to contact
an authorized Mercedes-Benz Center immedi-
ately to have the problem diagnosed and recti-
fied. If the problem is not resolved to your sat-
isfaction, please discuss the problem again with
the Mercedes-Benz Center or, if necessary, con-
tact us at one of the following addresses.
