Servicing the brakes
! The brake fluid level may be too low, if: R
if the red brake warning lamp lights up in
the instrument cluster and R
you hear a warning tone while the engine
is running
Observe additional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immedi-
ately. Consult a qualified specialist work-
shop to arrange this.
! A function or performance test should
only be carried out on a 2-axle dynamom-
eter. If you wish to operate the vehicle on
such a dynamometer, please consult a
qualified specialist workshop in advance.
You could otherwise damage the drive train
or the brake system.
! As the ESP ®
system operates automati-
cally, the engine and the ignition must be
switched off (the SmartKey must be in posi-
tion 0 or 1 in the ignition lock) if:R
the electric parking brake is tested on a
brake dynamometer (for a maximum of
ten seconds) R
the vehicle is towed with the front axle
raised.
Braking triggered automatically by ESP ®
may seriously damage the brake system.
All checks and maintenance work on the
brake system must be carried out at a quali-
fied specialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals.
You can find a description of Brake Assist
(BAS) on ( Y
page 66).
Mercedes-Benz recommends that you only
have brake pads/linings installed on your vehicle which have been approved for
Mercedes-Benz vehicles or which correspond
to an equivalent quality standard. Brake
pads/linings which have not been approved
for Mercedes-Benz vehicles or which are not
of an equivalent quality could affect your vehi-
cle's operating safety.
Mercedes-Benz recommends that you only
use brake fluid that has been specially
approved for your vehicle by Mercedes-Benz,
or which corresponds to an equivalent quality
standard. Brake fluid which has not been
approved for Mercedes-Benz vehicles or
which is not of an equivalent quality could
affect your vehicle's operating safety.
Checking brake lining thickness You can measure the break pad/lining thick-
ness using a test gage. Color-coding (green or
red) on the test gage allows you to determine
whether the brake pad/lining thickness is still
sufficient. The test gage is in the vehicle docu-
ment wallet in the glove box.

Driving tips
Driving and parking

Parking tips: R
On narrow roads, drive as close to the park-
ing space as possible. R
Parking spaces that are littered or over-
grown might be identified or measured
incorrectly. R
Parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly. R
Snowfall or heavy rain may lead to a parking
space being measured inaccurately. R
Pay attention to the PARKTRONIC
( Y
page 193) warning messages during the
parking procedure. R
You can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled. R
When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist. R
Never use Active Parking Assist when snow
chains are installed. R
Make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces: R
that are parallel or at right-angles to the
direction of travel R
that are on straight roads, not bends R
that are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. G WARNING
If there are objects above the detection range: R
Active Park Assist may steer too early R
the vehicle may not stop in front of these
objects
You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection
range ( Y
page 192).
Active Parking Assist does not assist you
parking in spaces at right angles to the direc-
tion of travel if: R
two parking spaces are located directly
next to one another R
the parking space is directly next to a low
obstacle such as a low curb R
you park forwards
Active Parking Assist does not assist you
parking in spaces that are parallel or at right
angles to the direction of travel if: R
the parking space is on a curb R
the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks R
the area is too small for the vehicle to
maneuver into R
the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer

General notes
Rear view camera C is an optical parking and
maneuvering aid. It uses guide lines to show
the area behind your vehicle in the Audio/
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text shown in the Audio/COMAND
display depends on the language setting.
The following are examples of rear view
camera messages in the Audio/COMAND
display.
Observe the notes on cleaning ( Y
page 306).
Important safety notes
The rear view camera is only an aid. It is not a
replacement for your attention to your imme-
diate surroundings. You are always responsi-
ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there
are no persons, animals or objects in the area
in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner: R
if the trunk lid is open R
in heavy rain, snow or fog R
at night or in very dark places R
if the camera is exposed to very bright light R
if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker) R

Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunc-
tion camera C which is attached behind the
top of the windshield. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A warning may be given if a front wheel
passes over a lane marking. It will warn you by
means of intermittent vibration in the steer-
ing wheel for up to 1.5 seconds. Important safety notes
G WARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may: R
give an unnecessary warning R
not give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
G WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane
Keeping Assist can neither reduce the risk of
an accident nor override the laws of physics.
Lane Keeping Assist cannot take into account
the road, traffic and weather conditions. Lane
Keeping Assist is merely an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
The Lane Keeping Assist does not keep the
vehicle in the lane.
The system may be impaired or may not func-
tion if: R
there is poor visibility, e.g. due to insuffi-
cient illumination of the road, or due to
snow, rain, fog or spray R
there is glare, e.g. from oncoming traffic,
the sun or reflection from other vehicles
(e.g. if the road surface is wet) R
the windshield is dirty, fogged up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera R
there are no, several or unclear lane mark-
ings for a lane, e.g. in areas with road con-
struction work Driving systems 207
