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 amanner
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 conditionsofy our 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.
Rar egularly 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
startin gthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain asafe 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.

Drive sensibly –save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to the rec-
ommended tire pressure.
RRemove unnecessary loads.
RRemove roof racksw hen they are not needed.
RWarm up the engineatlow engin espeeds.
RAvoid frequenta cceleration or braking.
RHave all maintenanc ework carried out as
indicated by the servicei ntervals in the Main- tenance Booklet or by the servicei
nterval dis-
play.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinkin gand driving and/or takin gdrugs and
driving are very dangerous combinations.
Even asmall amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of aserious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Thereforen ever leave
the engin erunning in enclosed spaces with-
out sufficientv entilation.
Certain engin esystems are designed to keep
the level of poisonous component sinexhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications .Always have
work on the engin ecarried out at aqualified
specialist workshop. Mercedes-Benz recom-
mends that you use an authorized Mercedes-
BenzC enter for this purpose. In particular, work
relevant to safety or on safety-related systems
must be carried out at aqualified specialist
workshop.
The engin esettings must not be changed under
any circumstances. Furthermore, all specific
servicew ork must be carried out at regular
intervals and in accordance with the Mercedes-
Benzs ervicer equirements. Details can be found
in the Maintenance Booklet.

Securing loads
Observe the following notes on securing loads:
RObserve the loading guidelines (Ypage 237).
RSecure the load using the cargo tie-down
rings.
RDistribute the load on the cargo tie-down
rings evenly.
RDo not use elastic straps or nets to secure a
load, as these are only intended as an anti-slip
protection for light loads.
RDo not route tie-downs across sharp edges or
corners.
RPad sharp edges for protection.
:Cargo tie-down rings
Stowage well under the trunk floor
Under the trunk floor you can findabracket for
TIREFIT and the vehicle tool kit, etc.
XTo open: pull handle :up.
XHook handle :into rain trough ;.
To enlarge the trunk you can remove the trunk
floor.
XTo remove: lift the trunk floor almost to rain
trough ;and pull it out.
XTo insert: place the trunk floor at the bottom

XHold sides of trunk floor =and press in the
direction of the arrow until it engages in
hooks ?.
Roof carrier
Important safety notes
GWARNING
When you load the roof, the center of gravity
of the vehicle rises and the driving character-
istics change. If you exceed the maximum roof
load, the driving characteristics, as well as
steering and braking, will be greatly impaired.
There is arisk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
Stowage areas241
Stowage and features
Z

!Mercedes-Benz recommends that you only
use roof carriers that have been tested and
approved for Mercedes-Benz vehicles. This
helps to prevent damage to the vehicle.
Position the load on the roof rack in such a
way that the vehicle will not sustain damage
even when it is in motion.
Depending on the vehicle equipment, ensure
that when the roof carrier is installed you can:
Ropen the panorama roof with power tilt/
sliding panel fully
Ropen the trunk lid fully
You will find information on the maximum roof
load in the "Technical data" section
(
Ypage 320).
An incorrectly secured roof carrier or roof load
may become detached from the vehicle. You
must therefore ensure that you observe the roof
carrier manufacturer's installation instructions.
Attaching the roof carrier
XOpen and fold the covers :upwards care-
fully in the direction of the arrow.
XOnly secure the roof carrier to the anchorage
points under covers :.
XObserve the manufacturer's installation
instructions.

GWARNING
The cup holder cannot hold acontainer secure
whilst traveling. If you use acup holder whilst
traveling, the container may be flung around
and liquid may be spilled. The vehicle occu-
pants may come into contact with the liquid
and if it is hot, they may be scalded. You may
be distracted from the traffic conditions and
you could lose control of the vehicle. There is
ar isk of an accident and injury.
Only use the cup holder when the vehicle is
stationary. Only use the cup holder for con-
tainers of the right size. Alwaysc lose the con-
tainer, particularlyift he liquid is hot.
GWARNING
If objects in the passenger compartment are
stowed incorrectly, they can slide or be
thrown around and hit vehicle occupants. In
addition, cupholders, open stowage spaces
and mobile phone brackets cannot always
retain all objects they contain. There is arisk
of injury, particularlyint he event of sudden
braking or asudden change in direction.
RAlwayss tow objects so that they cannot be
thrown around in such situations.
RAlwaysm ake sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets.
RClose the lockable stowage spaces before
starting ajourney.
RAlwayss tow and secure heavy, hard, poin-
ted, sharp-edged, fragile or bulky objects in
the trunk.
!Only use the cup holders for containers of
the right size and which have lids. The drinks
could otherwise spill.

MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat char-
acteristics) ,you can continue to drivey our vehi-
cle even if there is atotal loss of pressure in one
or moret ires.
MOExtended tires may only be used in conjunc-
tio nw ith an activated tir epressure loss warning
system (Canada only) or tir epressure monitor
(USAo nly) and only on wheels specifically tes-
ted by Mercedes-Benz.
Notes on driving with MOExtended tires with a
flat tir e(
Ypage 271).
Vehicles equipped with MOExtended tires are
not equipped with aTIREFIT kit at th efactory. It
is therefore recommended that you additionally
equip your vehicle with aTIREFIT kit if you mount
tires that do not feature run-flat properties, e.g.
winter tires. ATIREFI Tkit may be obtained from
aq ualified specialist workshop.
Winter operation
General notes
Have your vehicle winter-proofed at aqualified
specialist workshop at th eonset of winter.

PSI (pounds per squareinch)
Astandard unit of measure for tire pressure.
Aspect ratio
Relationship between tire height and tire width
in percent.
Tire pressure
This is pressure inside the tire applying an out-
ward force to each square inch of the tire's sur-
face. The tire pressure is specified in pounds per
square inch (psi), in kilopascal (kPa) or in bar.
The tire pressure should only be corrected when
the tires are cold.
Cold tire pressure
The tires are cold:
Rif the vehicle has been parked with the tires
out of direct sunlight for at least three hours
and
Rif the vehicle has not been driven further than
1m ile (1.6 km)
Tread
The part of the tire that comes into contact with
the road.
Bead
The tire bead ensures that the tire sits securely
on the wheel. There are several steel wires in the
bead to prevent the tire from coming loose from
the wheel rim.
Sidewall
The part of the tire between the tread and the
bead.
Weight of optional extras
The combined weight of those optional extras
that weigh more than the replaced standard
parts and more than 2.3 kg (5 lbs). These
optional extras, such as high-performance
brakes, level control, aroof rack or ahigh-per-
formanceb attery, are not included in the curb
weight and the weight of the accessories.
TIN (Tire Identification Number)
This is aunique identifier which can be used by
at ire manufacturer to identify tires, for example
for aproduct recall, and thus identify the pur-
chasers. The TIN is made up of the manufactur-
er's identity code, tire size, tire type code and
the manufacturing date.
Load bearing index
The load bearing index (also load index) is acode
that contains the maximum load bearing capa-
city of atire.
Traction
Traction is the result of friction between the tires
and the road surface.
Treadwear indicators
Narrow bars (tread wear bars) that are distrib-
uted over the tire tread. If the tire tread is level
with the bars, the wear limit of áin (1.6 mm)
has been reached.
Occupant distribution
The distribution of occupants in avehicle at their
designated seating positions.
Total load limit
Nominal load and luggage load plus 68 kg
(15 0lbs)m ultiplied by the number of seats in
the vehicle.
