Warning!G
Please note that objects which do not touch
the ground, such as the bumper of a vehicle
parked behind you, a trailer hitch, or the
back of a truck, may appear to be further
away than they actually are. In this case, you
should not use the guide lines to judge dis-
tance. The use of the guide lines to judge
distance increases the risk of impacting the
objects.
Warning!G
The Dynamic Rear View Monitor is a supple-
ment system. It is not intended to, nor does
it replace, the need for extreme care. The re-
sponsibility during parking and other driving
maneuvers always remains with the driver.
The Dynamic Rear View Monitor may show
obstacles with a distorted perspective, in-
correctly or not at all.
Special attention must be paid to objects
outside of the camera’s field of view such as
those located very close to or below the rear
bumper, or above the recessed grip of the
luggage compartment lid. Such objects may
not be detected by the system and can dam-
age the vehicle.
The Dynamic Rear View Monitor does not
warn you about impending collisions with
objects. The driver is always responsible for
safety and must continue to pay attention to
the immediate surroundings while parking
or maneuvering the vehicle. This applies not
only to the area behind the vehicle, but also
to the area in front of and to the sides of the
v e h i c l e . F a i l u r e t o d o s o c o u l d r e s u l t i n i n j u r y
to persons and/or damage to the vehicle or
other property. We also recommend that the
driver use the Parktronic system* or Park
Assist* when parking or maneuvering the
vehicle.Warning!G
Make sure no persons or animals are in the
area in which you are maneuvering. You
could otherwise injure them.
Warning!G
The Dynamic Rear View Monitor may not
function if:

the trunk lid is not completely closed

it is raining or snowing heavily, or if
there is thick fog

in a very dark area

the camera is exposed to very strong
white light (white stripes may appear on
the COMAND display)

the surrounding area is lit with fluores-
cent light (the COMAND display can
flicker)

outside temperatures are very high (lens
condensation)

System
Destination Download allows you access
to a database of over 10,000,000 points of
interest (POIs) that can be downloaded to
your vehicle’s navigation system. If you
know the destination the address can be
downloaded. Or if you are unsure of your
destination you can be provided with
points of interests near your location.
The Response Center can transmit desti-
nation data to the COMAND during the
connection with the Roadside Assistance
or Customer Assistance Center.
The transmitted data can contain address
details for a Mercedes-Benz Center or POIs
(points of interest).Route guidance
A prompt appears for confirmation if route
guidance to the address is to be started.
Slide rmq or rotate ymz to select
“Yes” menu item and confirm by
pressingn.

Assistance call or Information call are ac-
tive, an emergency call is still possible. In
this case, the emergency call will take pri-
ority and override all other active calls.
iThe components and operating principles of
COMAND can be found on (
page 81).
iIf you select “No”, you can save the address
in your address book (
page 214).
iThe destination download feature is avail-
able if the relevant mobile phone network is
available and data connection is possible.

Driving instructions
Brakes
To help prevent brake disk corrosion after
driving on wet road surfaces (particularly
salted roads), it is advisable to brake the
vehicle with considerable force prior to
parking. The heat generated serves to dry
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the
brakes by applying above-normal braking
pressure at higher speeds. This will also
enhance the grip of the brake pads.Refer to the description of the Brake Assist
System (BAS or BAS Plus*) (
page 66).
Brake pad wear or a leak in the system may
be the reason for low brake fluid level in
the reservoir.
The brake fluid level in the reservoir may
be too low if the red brake warning lamp in
the instrument cluster comes on while the
engine is running and an acoustic warning
sounds (
page 569). Observe additional
messages in the multifunction display that
may appear (
page 580).
Have the brake system inspected
immediately. Contact an authorized
Mercedes-Benz Center.
Warning!G
After driving in heavy rain for some time
without applying the brakes or through wa-
ter deep enough to wet brake components,
the first braking action may be somewhat
reduced and increased pedal pressure may
be necessary to obtain expected braking
effect. Maintain a safe distance from
vehicles in front.
Resting your foot on the brake pedal will
cause excessive and premature wear of the
brake pads.
It can also result in the brakes overheating,
thereby significantly reducing their effec-
tiveness. It may not be possible to stop the
vehicle in sufficient time to avoid an
accident.
!Because the ESP® operates automatically,
the engine and ignition must be shut off
(SmartKey in starter switch position0 or1 or
KEYLESS-GO start/stop button* in position0
or1) when

the electronic parking brake is being tested
on a brake test dynamometer

the vehicle is being towed with the
front/rear axle raised
Active braking action through the ESP
® may oth-
erwise seriously damage the brake system.
Warning!G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.

Warning!G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious per-
sonal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid in-
haling fumes and skin or clothing contact,
extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors are damaging to your
health.
iIn case that the central locking system does
not release the fuel filler flap, or the opening
mechanism is clamping, notify Roadside
Assistance or an authorized Mercedes-Benz
