Protecting the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in a manner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected by these factors:
Roperating conditions of your vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel con-
sumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Ra regularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal when
starting the engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain a safe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up to Ôof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel consump-
tion.
Environmental concerns and recom-
mendations
Wherever the Operator's Manual requires you to
dispose of materials, first try to regenerate or re-
use them. Observe the relevant environmental
rules and regulations when disposing of materi-
als. In this way you will help to protect the envi-
ronment.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also supplies reconditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new
parts.
!Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
Rdoors
Rdoor pillars
Rdoor sills
Rseats
Rcockpit
Rinstrument cluster
Rcenter 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 aftermarket accessories installed at a
qualified specialist workshop.
You could jeopardize the operating safety of
your vehicle if you use parts, tires and wheels as
well as accessories relevant to safety which
have not been approved by Mercedes-Benz. This
could lead to malfunctions in safety-relevant

Introduction

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, a speed bump or a pothole in the road
Ra 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 loads 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.

(40 km/h) and switch on the turn signal or
turn the steering wheel
Rif you are driving at speeds between 25 mph
(40 km/h) and 45 mph (70 km/h) and turn
the steering wheel
The cornering lamp may remain lit for a short
time, but is automatically switched off after no
more than three minutes.
Adaptive Highbeam Assist
General notes
You can use this function to set the headlamps
to change between low beam and high beam
automatically. The system recognizes vehicles
with their lights on, either approaching from the
opposite direction or traveling in front of your
vehicle, and consequently switches the head-
lamps from high beam to low beam.
The system automatically adapts the low-beam
headlamp range depending on the distance to
the other vehicle. Once the system no longer
detects any other vehicles, it reactivates the
high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control panel.
