Operating safety
Important safety notes
GWARNING
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.
GWARNING
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.
GWARNING
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:
Rthe vehicle becomes stuck, e.g. on a high
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb or a hole in the road
Ra heavy object strikes the undercarriage
or parts of the chassis
In situations like this, the body, the under-
carriage, chassis parts, wheels or tires
could be damaged without the damage
being visible. Components damaged in this
way can unexpectedly fail or, in the case of
24Introduction

an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible 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 specialist workshop. If on 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,
consult a qualified specialist workshop.
Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
USA: "The wireless devices of this vehicle
comply with Part 15 of the FCC Rules. Oper-
ation is subject to the following two condi-
tions: 1) These devices may not cause harm-
ful interference, and 2) These devices must
accept any interference received, including
interference that may cause undesired oper-
ation. Changes or modifications not expressly
approved by the party responsible for com-
pliance 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
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference, includ-
ing interference 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.
GWARNING
If you connect equipment to the diagnostics
connection in the vehicle, itmay affect the
operation of the vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There isa risk of an accident.
Do not connect any equipment to a diagnos-
tics connection inthe vehicle.
GWARNING
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
je opardized. 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 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
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the nec-
essary specialist knowledge, tools and quali-
fications to correctly carry out the work
required on your vehicle. This is especially the
case for work relevant to safety.

Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify an air bag system to
accommodate a person with disabilities, con-
tact an authorized Mercedes-Benz Center for
details. USA only: for further information con-
tact our Customer Assistance Center at
1-800-FOR-MERCedes (1‑800‑367‑6372).
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 a
few 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:
Rdoes not light up after the ignition is
switched on
Rdoes not go out after a few seconds with
the engine running
Rlights up again while the engine is running
GWARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.
PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG OFF indicator lamp :
and PASSENGER AIR BAG ON indicator
lamp ;are part of the Occupant Classifica-
tion System (OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the
front-passenger front air bag is enabled. If,
in the event of an accident, all deployment
criteria are met, the front-passenger front
air bag is deployed.
RPASSENGER AIR BAG OFF lights up: the
front-passenger front air bag is deactiva-
ted. It will then not be deployed in the event of an accident.
