Safety notes
G
Risk of accident and injury
Always have work on the vehicle carried out
by a qualified specialist workshop. In par-
ticular, work relevant to safety or on safety-
related systems as well as maintenance
work must be carried out at a qualified spe-
cialist workshop. The workshop must have
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. G
Risk of accident and injury
Some safety systems only function when
the engine is running. You should therefore
never switch off the engine when driving.
Otherwise the safety systems of your vehi-
cle may not function correctly and as a
result will no longer protect you and other
persons as intended. In addition, there is a
risk that you may lose control of your vehi-
cle and thus cause an accident. G
Risk of accident and injury
Work carried out incorrectly, or alterations
made to the vehicle, e.g. rerouting of cables
under coverings, could cause the safety
systems of your vehicle to stop working
properly. The safety systems would thus no
longer protect you and other persons as
intended. In addition, there is a risk that you
may lose control of your vehicle and thus
cause an accident.
All work and alterations to the vehicle, e.g.
installations or modifications, should there-
fore be carried out at a qualified specialist
workshop. G
Risk of accident
If you drive over obstacles at high speed or
if the vehicle bottoms out in rough terrain,
it could cause heavy impacts to the vehicle
underbody, tyres or wheels. This could
cause your vehicle to be damaged, which in
turn might lead to an accident. This also
applies to vehicles which are equipped with
underbody protection.
You should therefore drive over obstacles
slowly and prevent the vehicle from bot-
toming out when driving off-road. If neces-
sary, have your vehicle inspected at a
qualified specialist workshop. G
Risk of accident
If work on electronic equipment and its
software is carried out incorrectly, this
equipment could stop working. The elec-
tronic systems are networked via interfa-
ces. Tampering with these electronic sys-
tems could cause malfunctions in systems
which have not been modified. Malfunc-
tions such as these can seriously jeopard-
ise the vehicle's operating safety and
therefore your own safety.
You should therefore have all work and
modifications to electronic components
carried out at a qualified specialist work-
shop. Vehicle registration
Mercedes-Benz may ask its Service Centres
to carry out technical inspections on certain
vehicles to improve their quality or safety.
If you did not purchase your vehicle from an
authorised specialist dealer and your vehicle
has never been inspected at a Mercedes-
Benz Service Centre, it is possible that your
vehicle is not registered in your name with
Mercedes-Benz. Mercedes-Benz can only
inform you about vehicle checks if it has your
registration data. Introduction

Occupant safety
41carry out any modifications on the restraint
systems.
Never tamper with electronic components
and their software.
SRS (Supplemental Restraint System)
The SRS reduces the risk of occupants com-
ing into contact with the vehicle's interior in
the event of an accident. It can also reduce
the forces to which occupants are subjected
during an accident.
The SRS consists of:
R The 1 warning lamp
R belt tensioners
R belt force limiters
R airbags
The 1 1 warning lamp The SRS functions are checked regularly
when you turn on the ignition and when the
engine is running. Malfunctions can therefore
be detected in good time.
The
1 warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started. G
Risk of injury
If SRS is malfunctioning, individual systems
may be activated unintentionally or not be
deployed in the event of an accident with
heavy braking.
A malfunction has occurred if the 1
warning lamp:
R does not light up when you switch on the
ignition
R does not go out after the engine has been
running for a few seconds
R lights up again once the engine is running
In this case, have SRS checked immedi-
ately at a qualified specialist workshop.
Triggering of belt tensioners, belt force
limiters and airbags In the event of a collision, the sensor in the
airbag control unit evaluates important phys-
ical data such as duration, direction and force
of the vehicle deceleration or acceleration.
Based on the evaluation of this data and
depending on the vehicle's rate of longitudi-
nal deceleration in a collision, in the first
stage the airbag control unit pre-emptively
triggers the belt tensioners.i
The front belt tensioners can only be trig-
gered if the belt tongue is correctly
engaged in the seat belt buckle.
The front airbags are only deployed if there is
an even higher rate of vehicle deceleration in
a longitudinal direction.
Your vehicle has adaptive, dual stage front
airbags. When the first activation threshold is
reached, the front airbag is filled with enough
propellant gas to reduce the risk of injuries.
The front airbag is only fully inflated if a sec-
ond threshold is reached within a few milli-
seconds, due to the control unit having
detected further deceleration.
Criteria for triggering belt tensioners and
airbags
In the first stage of a collision, the airbag con-
trol unit evaluates the duration and direction
of vehicle acceleration or deceleration in
order to determine whether it is necessary to
trigger the belt tensioner and/or airbag.
The belt tensioner and airbag triggering
thresholds are variable and are adapted to the
rate of deceleration of the vehicle. This proc-
ess is pre-emptive in nature as the airbag
must be deployed during – and not at the end
of – the collision. Safety

Risk of accident
If the v warning lamp in the instrument
cluster flashes, proceed as follows:
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Accelerate less when driving.
R Adapt your driving style to suit prevailing
road and weather conditions.
The vehicle could otherwise go into a skid.
If you drive too fast, 4-ETS cannot reduce
the risk of an accident. 4-ETS cannot over-
ride the laws of physics.
! Only operate the vehicle briefly (for a max-
imum of ten seconds) on a brake dyna-
mometer. Turn the key in the ignition lock
to position 0or 1. You could otherwise
damage the drive train or the brake system.
! A function or performance test should
only be carried out on a twin-axle dyna-
mometer. If you wish to operate the vehicle
on such a dynamometer, please consult a
Mercedes-Benz Service Centre in advance.
You could otherwise damage the drive train
or the brake system. i
If heavy demands are made on the brakes,
4-ETS switches off automatically for a brief
period so that the brakes do not heat up
further. If, for this reason, 4-ETS does not
engage, the vwarning lamp in the
instrument cluster lights up. The message
ABS, ESP unavailable see Owner's
Manual also appears in the multi-function
display.
! The engine may be switched on when the
vehicle is towed with its axle raised or when
the parking brake is checked on the brake
dynamometer. Application of the brakes
via 4-ETS may otherwise destroy the brake
system.
Off-road 4-ETS A 4-ETS system specifically suited to off-road
terrain is activated automatically if the off-
road drive program is activated
(Y page 140) or the LOW RANGE* off-road
gear is selected (Y page 141). Distance warning system (only for
vehicles with Distronic*)
This function will issue a warning at speeds of
around 30 km/h or more if:
R for a period of several seconds, the dis-
tance to the vehicle in front is too short for
the speed at which you are travelling. The
distance warning lamp lin the instru-
ment cluster will then light up.
R you are approaching the vehicle in front too
rapidly. An intermittent warning tone will
then sound and the distance warning lamp
l will light up in the instrument cluster.
In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
crash, you must apply the brakes yourself. G
Risk of accident
Pay particular attention to the traffic con-
ditions if the distance warning lamp l
in the instrument cluster lights up or an
intermittent warning tone sounds.
If necessary, brake or swerve to avoid an
obstacle. Safety

Restoring the factory settings X
Press the kandj buttons simulta-
neously for approximately six seconds until
the battery check lamp flashes twice. KEYLESS GO*
The optional equipment supplied with your
vehicle includes two KEYLESS GO keys. You
can start, lock or unlock the vehicle using the
KEYLESS GO key. To do this, you need only
carry the KEYLESS GO key on your person.
When you touch the surface of the sensors on
the vehicle's door handles, KEYLESS GO
establishes a radio connection between the
vehicle and the key. The distance between
the KEYLESS GO key and the vehicle's door
handle from which you wish to lock or unlock
the vehicle, must not be greater than 1 m.
When you pull the door handle, the following
unlock centrally if the factory settings have
not been changed:
R the doors
R the tailgate
R the fuel filler flap
If you pull on the handle of the tailgate, only
the tailgate of your vehicle is unlocked.
When starting the engine and whilst driving,
KEYLESS GO also checks whether a valid
KEYLESS GO key is in the vehicle by periodi-
cally establishing radio contact. G
Risk of accident
If children are left unsupervised in the vehi-
cle, they could open a door from the inside,
even if it has been locked. Or they could
start the vehicle if a valid KEYLESS GO key
is in the vehicle and they press the KEY-
LESS GO button on the ignition lock. They
could endanger themselves and others.
Never leave children unsupervised in the
vehicle. Switch off the engine and take the
KEYLESS GO key with you, even if you are
only leaving the vehicle for a short time. 1

Risk of accident
Only adjust the steering wheel when the
vehicle is stationary and do not pull away
until the steering wheel adjustment mech-
anism is locked in position. You might oth-
erwise drive without the steering wheel
adjustment mechanism being locked in
position. As a result you could be distracted
from road and traffic conditions by an unex-
pected movement of the steering wheel
and thereby cause an accident.
The steerability of the vehicle is however
not affected.
X Check whether seat 3and the head
restraint are adjusted properly
(Y page 76).
Make sure that:
R you are as far away from the driver's front
airbag as possible
R you are sitting in a normal upright posi-
tion
R you can fasten the seat belt properly
R you have moved the backrest to an
almost vertical position R
you have set the seat angle so that your
thighs are gently supported
R you can depress the pedals properly
R you have adjusted the head restraint so
that the back of your head is supported

For safety reasons, Mercedes-Benz recom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, daytime operation of headlamps varies
due to legal and voluntary requirements. In
these countries, the dipped-beam headlamps
are automatically switched on when the
engine is started.
i If you drive in countries in which traffic
drives on the opposite side of the road to
the country where the vehicle is registered,
oncoming traffic may be dazzled by the
asymmetrical dipped-beam headlamps.
Have the headlamps changed to symmet-
rical dipped beam when driving in these
countries. You can obtain information
about this from any Mercedes-Benz Service
Centre. Controls
