Environmental note
Daimler's declared policy is one of
comprehensive 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
environmentally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected
by these factors:
R operating condition sofyour vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel
consumption.
R always make sure that the tire pressures
are correct.
R do not carry any unnecessary weight.
R remove roof racks once you no longer need
them.
R ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
startingt he engine.
R do not warm up the engine when the vehicle
is stationary.
R drive carefully and maintain asafe distance
from the vehicle in front.
R avoid frequent, sudden acceleration and
braking. R
change gear in good time and use each gear
only up to 001Bof its maximum engine speed.
R switch off the engine in stationary traffic.
R keep an eye on the vehicle's fuel
consumption. Environmental concerns and
recommendations
Wherever the operating instructions require
you to dispose of materials, first try to
regenerate or re-use them. Observe the
relevant environmental rules and regulations
when disposing of materials. In this way you
will help to protect the environment. Genuine Mercedes-Benz parts

for example, the power steering and the brake
boosting effect.Y ou will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If you operate mobile communication
equipment while driving, you will be
distracted from traffic conditions. You could
also lose control of the vehicle. There is arisk
of an accident.
Only operate this equipment when the vehicle

(approximately 50 km/h) ,the vehicle covers
ad istance of 44 ft (approximately 14 m) per
second.
Drive sensibly –save fuel Observe the following tips to save fuel:
R The tires should always be inflated to the
recommended tire pressure.
R Remove unnecessary loads.
R Remove roof racks whe nthey are not
needed.
R Warm up the engine at low engine speeds.
R Avoid frequent acceleration or braking.
R Have all maintenancew ork carried out as
indicated by the service intervals in the
MaintenanceB ooklet or by the service
interval display.
Fuel consumption also increases when

fcarrier
Important safety notes G
WARNING
Whe nyou load the roof, the center of gravity
of the vehicle rises and the driving
characteristics change. If you exceed the
maximum roof load, the driving
characteristics, as well as steering and
braking, will be greatly impaired. There is a
risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
! 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.
Ensure that, depending on the vehicle's
equipment, you can raise the panorama
roof with power tilt/sliding panel fully and
open the tailgate fully when the roof carrier
is installed.
The maximum roof load is 165 lbs((75 kg).
An incorrectly secured roof carrier or roof
load may become detached from the vehicle.
You must therefor eensure that you observe
the roof carrier manufacturer' sinstallation
instructions.
Attaching the roof carrier X
Open covers 001Acarefully in the direction of
the arrow.
X Fold covers 001Aupwards.
X Only secure the roof carrier to the
anchorage points under covers 001A.

Treadwear indicator s(TWI) are required by
law. Six indicator sare positioned on the tire
tread. The yare visible once the trea ddepth
is approximately 0003in (1.6 mm). If this is the
case ,the tire is so worn that it mus tbe
replaced. Selecting, mounting and replacing
tires
R Only mount tires and wheels of the same
type and make.
Exception: it is permissible to install a
different type or make in the event of aflat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
(Y page2 95).
R Only mount tires of the correct size onto
the wheels.
R After mounting new tires, brea kthem in at
moderate speeds for the first 60 miles
(100 km), as they only reach their full
performance after this distance.
R Do not drive with tires which have too little
tread depth, as this significantly reduces
the traction on wet roads (hydroplaning).
R Replace the tires after six years at the
latest, regardless of wear. MOExtended tires (tires with run-flat
properties)
With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is atotal loss of
pressure in one or more tires.
MOExtended tires may only be used in
conjunction with an active tire pressure loss
warning system and only on wheels
specifically tested by Mercedes-Benz.
Notes on driving with MOExtended tires with
af lat tire (Y page 295). i
Vehicles equipped with MOExtended tires
are not equipped with aTIREFIT kit at the
factory. It is therefore recommended that
you additionallye quip your vehicle with a
TIREFIT kit if you mount tires that do not
feature run-flat properties, e.g. winter tires.
AT IREFIT kit can be obtained from a
qualified specialist workshop. Winter operation
General notes
Have your vehicle winterproofed at aqualified
specialist workshop at the onset of winter.
Observe the notes in the "Changing awheel"
section (Y page 336). Driving with summer tires
At temperatures below 45 ‡(+7 †), summer
tires lose elasticity and therefore traction and
braking power. Change the tires on your
vehicle to M+S tires. Using summe rtires at
very cold temperatures coul dcause cracks to
form, thereb ydamaging the tires
permanently. Mercedes-Benz cannot accept
responsibility for this type of damage. M+S tires
G
WARNING
M+S tires with atire tread depth of less than
0015 in (4 mm) are not suitabl efor use in winter
and do not provide sufficient traction. There
is ar isk of an accident.
M+S tires with atread depth of less than 0015
in (4 mm) must be replaced immediately.
At temperatures below 45 ‡(+7 †), use
winter tires or all-season tires. Both type sof
tire are identified by the M+S marking.
Only winter tires bearing the 000Esnowflake
symbol in addition to the M+S marking
provide the best possibl egrip in wintry road
conditions. Only these tires will allow driving 314
