If you believe that your vehicle has ad efect
which could cause ac rash or could cause injury
or death, you should immediately inform the
National Highway Traffic Safety Administration
(NHTSA )ina ddition to notifying Mercedes-Benz
USA ,L LC.
If NHTSA receives similar complaints ,itm ay
open an investigation, and if it finds that as afety
defect exists in ag roup of vehicles, it may order
ar ecall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or Mercedes-Benz
USA ,L LC.
To contact NHTSA ,y ou may call the Vehicle

! Follow the instructions in this manual about
the proper operation of your vehicle as well as
about possible vehicle damage. Damage to
your vehicle that arises from culpable contra-
ventions against these instructions is not cov-

QR codes for the rescue card
The QR codes are secured in the fuel filler flap
and on the opposite side on the B-pillar. In the
event of an accident ,r escue services can use
the QR code to quickly find the appropriate res-
cue card for your vehicle. The current rescue
card contains the most important information
about your vehicle in ac ompact form, e.g. the
routing of the electric cables.
You can find more information under
www.mercedes-benz.de/qr-code. Data stored in the vehicle
Data storage Aw ide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about: R
the vehicle's operating state R
incidents R
malfunctions
In general, this technical information docu-
ment st he state of ac omponent, am odule, a
system or the surroundings.
These include, for example: R
operating conditions of system components,
e.g. fluid levels R
the vehicle's status messages and those of its
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-
ment ,l ateral acceleration, accelerator pedal
position R
malfunction sa nd defects in important system
components, e.g. lights, brakes R
vehicle reaction sa nd operating conditions in
special driving situations, e.g. air bag deploy-
ment ,i ntervention of stability control sys-
tems R
ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to: R
assist in recognizing and rectifying malfunc-
tions and defects R
analyze vehicle functions, e.g. after an acci-
dent R
optimize vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory
and malfunction data memory.
Services include, for example: R
repair services R
service processes R
warranties R
quality assurance

Safety 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: R
open the panorama roof with power tilt/
sliding panel fully R
open the trunk lid fully
You will find information on the maximum roof
load in the "Technical data" section
( Y
page 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
X
Open and fold the covers C upwards care-
fully in the direction of the arrow. X
Only secure the roof carrier to the anchorage
points under covers C .X
Observe the manufacturer's installation
instructions.

Cup holder
Important safety notes
G WARNING
The cup holder cannot hold ac ontainer secure
whilst traveling. If you use ac up 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. Alway sc lose the con-
tainer, particularl yift he liquid is hot.
G WARNING
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 ar isk
of injury, particularl yint he event of sudden
braking or as udden change in direction. R
Alway ss tow objects so that they cannot be
thrown around in such situations. R
Alway sm ake sure that objects do not pro-
trude from stowage spaces, parcel nets or
stowage nets. R
Close the lockable stowage spaces before
starting aj ourney. R
Alway ss 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.
Observe the loading guidelines ( Y

Brake fluid
G WARNING
The brake flui dc onstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,v apo rp ockets may form in the
brake system when the brakes are applied
hard. This would impair braking efficiency.
There is ar isk of an accident.
You should have the brake flui dr enewe da t
the specified intervals.
When handling brake fluid, observe the impor-
tant safety notes on service products
( Y
pag e3 15).
The brake flui dc hange interval sc an be found in

Only use brake flui da pproved by Mercedes-
Benz in accordance with MB-Freigabe or MB-
Approva l3 31.0.
Information about approved brake flui dc an be
obtained at any qualified specialist workshop or
on the Internet at
http://bevo.mercedes-benz.com. i Have the brake flui dr egularl yr eplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Coolant
Important safety notes
G WARNING
If antifreeze comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is ar isk of fire and injury.
Let the engine cool down before you add anti-
freeze. Make sure that antifreeze is not spilled
next to the filler neck. Thoroughly clea nt he
antifreeze from components before starting
the engine.
! Only add coolant that has been premixed
with the desired antifreeze protection. You
coul do therwise damage the engine.
Further information on coolants can be found
in the Mercedes-Benz Specifications for Ser-
vice Products, MB BeVo 310.1, e.g. on the
Internet at http://bevo.mercedes-benz.com.
Or contact aq ualified specialist workshop.
! Always use as uitable coolant mixture, even
in countries where high temperatures prevail.
Otherwise, the engine cooling system is not
sufficiently protected from corrosio na nd
overheating.
i Have the coolant regularl yr eplaced at a
qualified specialist workshop and the replace-
ment confirmed in the Maintenance Booklet.
Comply with the important safety precautions
for service products when handling coolant
( Y

The coolant is am ixture of water and corrosion
inhibitor/antifreeze concentrate. It performs
the following tasks: R
Anti-corrosion protection R
Antifreeze protection R
Raising the boiling point
