When the air bags are deployed, a small
amount of powder is released. The powder
generally does not constitute a health hazardand does not indicate that there is a fire in the
vehicle. In order to prevent potential breath-
ing difficulties, you should leave the vehicle as soon as it is safe to do so. If you have any
breathing difficulty but cannot get out of the
vehicle after the air bag inflates, then get fresh
air by opening a window or door.
GWARNING
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a col- lision, you must always be in the normal seat
position with your back against the backrest.
Fasten your seat belt and make sure that it is
correctly positioned on your body.
As the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be seriously injured or killed by an air bag, as it
inflates with great force instantaneously:
R sit with the seat belt fastened correctly and
in a position that is as upright as possible
with your back against the backrest.
R move the driver's seat as far back as pos-
sible, still permitting proper operation of
vehicle controls. The distance from the cen-
ter of the driver's chest to the center of the
air bag cover on the steering wheel must be
at least 10 inches (25 cm). You should be
able to accomplish this by adjusting the
seat and steering wheel. If you have any
difficulties, please contact an authorized
Mercedes-Benz Center.
R do not lean your head or chest close to the
steering wheel or dashboard.
R only hold the steering wheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severity of
hand/arm injury if the driver front air bag
inflates.
R adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R occupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates. This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt prop-
erly and use an appropriately sized infant
restraint, toddler restraint or booster seat
recommended for the size and weight of the child.
Failure to follow these instructions can result in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety informa-
tion. Be sure to give the buyer this Operator's
Manual.
If the air bags are deployed, you will hear a
bang, and a small amount of powder may also be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard and does not indicate that thereis a fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple with asthma or other breathing trouble. To
avoid this, you may wish to get out of the
vehicle or open the windows as soon as it is
safe to do so. The 6 SRS warning lamp
lights up.
The air bags are deployed if the air bag control
unit detects the need for deployment. Only in the event of such a situation will the air bags
provide their supplemental protection.
If the driver and front passenger do not wear their seat belts, it is not possible for the air
bags to provide their supplemental protec-
tion.

Crash-responsive EASY-EXIT feature
If the crash-responsive EASY-EXIT feature is
triggered in an accident, the steering columnwill move upwards when the driver's door is
opened. This occurs irrespective of the posi-
tion of the SmartKey in the ignition lock. This
makes it easier to exit the vehicle and rescue
the occupants.
The crash-responsive EASY-EXIT feature is
only operational if the EASY-EXIT/ENTRY fea- ture is activated in the on-board computer.

GWARNING
You could lose control of your vehicle if you do the following while driving:
R adjust the driver's seat, head restraint,
steering wheel or mirrors
R fasten the seat belt
There is a risk of an accident.
Adjust the driver's seat, head restraint, steer-
ing wheel and mirror and fasten your seat belt before starting the engine.
GWARNING
The exterior mirror on the front-passenger
side reduces the size of the image. Visible
objects are actually closer than they appear.
This means that you could misjudge the dis-
tance from road users traveling behind, e.g.
when changing lane. There is a risk of an acci-
dent.
For this reason, always make sure of the
actual distance from the road users traveling
behind by glancing over your shoulder.
The convex exterior mirrors provide a larger
field of vision.
The exterior mirrors are automatically heated
after starting the vehicle if the rear window
defroster is switched on and the outside tem- perature is low. Heating takes a maximum of
10 minutes.
iYou can also heat up the exterior mirrors
manually by switching on the rear window
defroster.
X Make sure that the SmartKey is in position
1 or 2 in the ignition lock ( Y page 149).

Useful information
iThis Operator's Manual describes all
models and all standard and optional equip- ment of your vehicle available at the time of
publication of the Operator's Manual.
Country-specific differences are possible.
Please note that your vehicle may not be
equipped with all features described. This
also applies to safety-related systems and

ist workshops ( Y page 27).
Loading guidelines
GWARNING
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.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open.
GWARNING
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 gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occu-
pants and luggage/cargo.
The gross load limit and the gross vehicle
weight rating (GVWR) for your vehicle must
never be exceeded. The gross load limit and
the GVWR are specified on the vehicle iden-
tification plate on the B-pillar of the driver's
door ( Y page 343).
The load must also be distributed so that the
weight on each axle never exceeds the gross axle weight rating (GAWR) for the front and
rear axles. The specifications for GVWR and
GAWR are on the vehicle identification plate
on the B-pillar of the driver's door
( Y page 343).
Further information can be found in the
"Loading the vehicle" section ( Y page 343).
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 The cargo compartment is the preferred
place to carry objects.
R Position heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible.
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.

Make sure that they are not endangered as
they do so.
X Make sure that no one is near the danger
area while a wheel is being changed. Any-
one who is not directly assisting in the
wheel change should, for example, stand
behind the barrier.
X Get out of the vehicle. Pay attention to traf-
fic conditions when doing so.
X Close the driver's door.
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally 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 quali-
fied specialist workshop.
MOExtended tires (tires with run-flat
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 349). MOExtended tires may only be used in con-
junction 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 255).
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 and approximately
18 miles (30 km) when the vehicle is fully
laden.
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/maneuvers, or it can be increased
through a moderate style of driving.
The driving distance possible in run-flat modeis counted from the moment the tire pressure
loss warning appears in the multifunction dis-
play.
You must not exceed a maximum speed of
50 mph (80 km/h).
iWhen 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 stand-
ard tire may be used as a temporary meas- ure. Make sure that you use the proper size
and type (summer or winter tire).
iVehicles equipped with MOExtended tires
are not equipped with a TIREFIT kit at the
factory. It is therefore recommended that
you additionally equip your vehicle with a
