Important safety notes
G WARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legal requirements for
the country in which you are currently driving
when operating the on-board computer.
G WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages
or warnings from certain systems in the mul-
tifunction display. You should therefore make sure your vehicle is operating safely at all
times.
If the operating safety of your vehicle is
impaired, pull over as soon as it is safe to do
so. Contact a qualified specialist workshop.
For an overview, see the instrument panel
illustration ( Y
page 31).
Displays and operation
Instrument cluster lighting The light sensor in the instrument cluster
automatically controls the brightness of the
multifunction display. In daylight, the displays
in the instrument cluster are not illuminated.
The lighting in the instrument cluster, in the
displays and the controls in the vehicle inte-
rior can be adjusted using the brightness con-
trol knob.
The brightness control knob is located on the
bottom left of the instrument cluster
( Y
page 31). X
Turn the brightness control knob clockwise
or counter-clockwise.
If the light switch is set to the X , ` or
X position, the brightness is dependent
upon the brightness of the ambient light.

Loading guidelines
G WARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Exhaust
gases can enter the vehicle interior if the
trunk lid is open when the engine is running,
especially if the vehicle is in motion. There is a
risk of poisoning.
Always switch off the engine before opening
the trunk lid. Never drive with the trunk lid
open.
G WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury. Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load: R
Never exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants).
The values are specified on the vehicle
identification plate on the B-pillar of the
driver's door. R
The trunk is the preferred place to carry
objects. R
Position heavy loads as far forwards as pos-
sible and as low down in the trunk as pos-
sible. R
The load must not protrude above the
upper edge of the seat backrests. R
Always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place. R
Always place the load behind unoccupied
seats if possible. R
Use the cargo tie-down rings and the parcel
nets to transport loads and luggage. R
Use cargo tie-down rings and fastening
materials appropriate for the weight and
size of the load. R
Secure the load with sufficiently strong and
wear-resistant tie-downs. Pad sharp edges
for protection.272

and rinse off the treated areas afterwards. X
Soak bird droppings with water and rinse
off the treated areas afterwards. X
Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid. X
Use tar remover to remove tar stains. X
Use silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products recom-
mended and approved by Mercedes-Benz.
This is the case approximately every three to
five months, depending on the climate con-
ditions and the care product used.
If dirt has penetrated the paint surface or if
the paint has become dull, the paint cleaner
recommended and approved by Mercedes-
Benz should be used.

properties)
General notes With MOExtended tires (tires with run flat
characteristics), you can continue to drive
your vehicle even if there is a total loss of
pressure in one or more tires. The affected
tire must not show any clearly visible damage.
You can recognize MOExtended tires by the
MOExtended marking which appears on the
sidewall of the tire. You will find this marking
next to the tire size designation, the load-
bearing capacity and the speed index
( Y
page 345).
MOExtended tires may only be used in con-
junction with an active tire pressure loss
warning system or with an active tire pressure
monitor.
If a pressure loss warning message
appears in the multifunction display: R
observe the instructions in the display mes-
sages ( Y
page 250). R
check the tire for damage. R
if driving on, observe the following notes.
The driving distance possible in run-flat mode
is approximately 50 miles (80 km) when the
vehicle is partially laden. When the vehicle is
fully laden it is approximately 19 miles
(30 km).
In addition to the vehicle load, the driving dis-
tance possible depends upon: R
vehicle speed R
road condition R
outside temperature
The driving distance possible in run-flat mode
may be reduced by extreme driving condi-
tions or maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat mode
is counted from the moment the tire pressure
loss warning appears in the multifunction dis-
play. Flat tire 311
Breakdown assistance

You must not exceed a maximum speed of
50 mph (80 km/h).
When replacing one or all tires, please
observe the following specifications for your
vehicle's tires: R
size R
type and R
the "MOExtended" mark
If a tire has gone flat and cannot be replaced
with a MOExtended tire, a standard tire may
be used as a temporary measure. Make sure
that you use the proper size and type (sum-
mer or winter tire).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if
you mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit may
be obtained from a qualified specialist work-
shop.
Important safety notes
G WARNING

Operation
Information on driving
Check the tire pressure when the vehicle is
heavily laden and adjust prior to a trip.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that
the wheels or tires are damaged. If you sus-
pect that a tire is defective, reduce your
speed immediately. Stop the vehicle as soon
as possible to check the wheels and tires for
damage. Hidden tire damage could also be
causing the unusual handling characteristics.
If you find no signs of damage, have the tires
and wheels checked at a qualified specialist
workshop.328
Operation
Wheels and tires

Only use tires, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, tire dimen-
sion variations could cause the tires to
come into contact with the bodywork and
axle components. This could result in dam-
age to the tires or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those tes-
ted and approved.
Information on tires, wheels and approved
combinations can be obtained from any
qualified specialist workshop.
! Retreaded tires are neither tested nor rec-
ommended by Mercedes-Benz, since pre-
vious damage cannot always be detected
on retreaded tires. As a result, Mercedes-
Benz cannot guarantee vehicle safety if
retreaded tires are mounted. Do not mount
used tires if you have no information about
their previous usage.
Overview of abbreviations used in the follow-
ing tire tables: R
BA: both axles R
FA: front axle R
RA: rear axle
The recommended pressures for various
operating conditions can be found: R
on the Tire and Loading Information placard
on the B-pillar on the driver's side R
in the tire pressure table in the fuel filler flap
Observe the notes on recommended tire
pressures under various operating conditions
( Y
page 332).
Check tire pressures regularly, and only when
the tires are cold. Comply with the mainte-
nance recommendations of the tire manufac-
turer in the vehicle document wallet. Notes on the vehicle equipment – always
equip the vehicle with: R
with tires of the same size on a given axle
(left and right) R
the same type of tires at a given time (sum-
mer tires, winter tires, MOExtended tires)
Exception: it is permissible to install a dif-
ferent type or make in the event of a flat
tire. Observe the "MOExtended tires (tires
with run-flat characteristics" section
( Y
page 311).
Vehicles equipped with MOExtended tires are
not equipped with a TIREFIT kit at the factory.
It is therefore recommended that you addi-
tionally equip your vehicle with a TIREFIT kit if
you mount tires that do not feature run-flat
properties, e.g. winter tires. A TIREFIT kit may
be obtained from a qual ified specialist work-
shop.

available at the factory for all countries.
i The following pages contain information
on approved wheel rims and tire sizes for
equipping your vehicle with winter tires.
Winter tires are not available at the factory
as standard equipment or optional extras.
If you want to equip your vehicle with
approved winter tires, it may be necessary
to obtain wheel rims in the corresponding
size. The size of the approved winter tires
may differ from the standard tires. This is
dependent on the model and the equip-
ment installed at the factory.
