Important safet y notesIf you fail to adapt your drivin g style or if you are
inattentive , th e drivin g safet y systems can nei-
ther reduce th e ris k of an acciden t no r override
th e laws of physics. Driving safet y systems are
merely aids designed to assist driving. You are
responsible fo r maintainin g th e distanc e to th e
vehicle in front, fo r vehicle speed, fo r braking in
goo d time, and fo r stayin g in lane. Always adapt
your drivin g style to suit th e prevailin g road and
weather condition s and maintain a saf e distanc e
from th e vehicle in front. Drive carefully.
The drivin g safet y systems described only wor k
as effectively as possible when there is ade-
quat e contact between th e tires and th e road
surface. Pay particular attention to th e informa-
tion regardin g tires , recommended minimum
tire tread depths etc. in th e "Wheels and tires "
section ( Y
page 292).
In wintr y drivin g conditions, always use winte r
tires (M+ S tires )a nd if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible. ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such a way that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The % ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 64).
G WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally, further driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at a qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp ( Y
page 229) and dis-
play messages which may be shown in the
instrument cluster ( Y
page 204).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over. X
To make a full brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extra care while driving.64

Safety

Drivin g on wet road s
Hydroplaning If water has accumulated to a certain dept h on
th e road surface, there is a danger of hydro-
planin g occurring, eve n if:R
you drive at low speeds .R
th e tires hav e adequat e tread depth.
Fo r this reason , in th e event of heav y rain or in
condition s in whic h hydroplaning may occur ,
you mus t drive in th e followin g manner:R
lowe r your speed.R
avoid ruts. R
avoid sudden steerin g movements .R
brake carefully.
Drivin g on flooded road s
! Do no t drive through floode d areas. Chec k
th e dept h of any water befor e drivin g through
it . Drive slowly through standin g water. Oth-
erwise , water may ente r th e vehicle interio r or
th e engin e compartment. Thi s can damage
th e electronic component s in th e engin e or
th e automatic transmission. Water can also
be drawn in by th e engine's air suction nozzles
and this can cause engin e damage.
Winte r drivin g
G WARNING
If you shift down on a slipper y road surfac e in
an attempt to increase th e engine's braking
effect , th e drive wheels could los e their grip.
There is an increase d danger of skidding and
accidents .
Do no t shift down fo r additional engin e brak-
in g on a slipper y road surface.
G DANGER
If th e exhaus t pipe is blocke d or adequat e
ventilation is no t possible, poisonous gases
suc h as carbon monoxide (CO) may ente r th e
vehicle. Thi s is th e case, e.g. if th e vehicle
becomes trappe d in snow. There is a ris k of
fatal injury. If you leav e th e engin e or th e auxiliar y heatin g
running , mak e sur e th e exhaus t pipe and are a
around th e vehicle are clear of snow. To
ensur e an adequat e supply of fresh air, ope n a
window on th e sid e of th e vehicle that is no t
facin g into th e wind.
Hav e your vehicle winter-proofed at a qualified
specialis t workshop at th e onset of winter.
Drive particularly carefully on slipper y road sur -
faces. Avoid sudden acceleration , steerin g and
braking maneuvers . Do no t use th e cruise con-
trol or DISTRONIC PLUS.
If th e vehicle threatens to skid or canno t be
stopped when movin g at low speed:X
Shift th e transmissio n to position N .
The outsid e temperature indicator is no t
designed to serve as an ice-warnin g devic e and
is therefore unsuitable fo r that purpose.
Changes in th e outsid e temperature are dis -
playe d after a short delay.
Indicated temperature s just abov e th e freezin g
poin t do no t guarantee that th e road surfac e is
free of ice. The road may still be icy, especially in
wooded areas or on bridges. The vehicle could
skid if you fail to adapt your drivin g style. Always
adapt your drivin g style and drive at a speed to
suit th e prevailin g w eather conditions.
You should pay special attention to road condi-
tion s when temperature s are around freezin g
point.

G WARNIN G
When th e vehicl e is bein g lowered, people
could become trapped if their limb s are
between th e vehicl e body and th e wheels or
underneat h th e vehicle. There is a ris k of
injury.
Mak e sur e no on e is underneat h th e vehicl e or
in th e immediat e vicinity of th e whee l arches
when th e vehicl e is bein g lowered.
Your vehicl e regulates it s height automatically.
All-roun d level control ensures th e best possibl e
suspension and constan t ground clearance ,
eve n wit h a laden vehicle. When you drive fast,
th e vehicl e is lowered automatically to improve
drivin g safet y and to reduce fuel consumption .
The followin g vehicl e levels are possible:R
Normal R
Raised : th e vehicl e is raised by approximately
0.80 in (20 mm ) when compared with the nor-
mal level R
Lowered: the vehicle is raised by approx-
imately 0.40 in (10 mm ) when compared with
the normal level
i These changes in level are so slight that you
are hardly aware of them.
The "Normal" and "Raised" vehicle levels can be
set manually.
The "Lowered” vehicle level is set automatically: R
at speeds above 70 mph (113 km/h) R
if you have selected "Sports tuning"
( Y

Setting the vehicle level
Select the "Normal" setting for normal road sur-
faces and "Raised" for driving with snow chains
or on particularly poor road surfaces. YourDriving systems 159
Driving and parking Z

4MATIC (permanent four-wheel drive) If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of accident nor override
the laws of physics. 4MATIC cannot take
account of road, weather and traffic conditions.
4MATIC is only 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.
If a drive wheel spins due to insufficient grip: R
Only depress the accelerator pedal as far as
necessary when pulling away. R
Accelerate less when driving.
! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz Limited Warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tires (M+S tires), with snow chains
if necessary.
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP ®
, it improves
the traction of your vehicle whenever a drive
wheel spins due to insufficient grip.
PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area around
your vehicle using six sensors in the front
bumper and six sensors in the rear bumper.
PARKTRONIC indicates visually and audibly the
distance between your vehicle and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. When maneuvering, parking or pulling
out of a parking space, make sure that there are
no persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such as flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in
the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on a truck
or a pneumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you: R
switch on the ignition R
shift the transmission to position D , R or NR
release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
Range of the sensors
General notes PARKTRONIC does not take objects into con-
sideration that are: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, e.g. overhanging
loads, truck overhangs or loading ramps.
C
Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them ( Y
page 274).Driving systems 163
Driving and parking Z

for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist is also unavailable.
G WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park-
ing Assist parking procedure.
! If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for park-
ing, for example: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
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 164) 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 tires are inflated to the
specified tire pressure. This has a direct influ- ence on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces: R
parallel or at right angles to the direction of
tra vel R
on the same level as the road, e.g. not on the
pavement R
on straight roads, not bends
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 cal-
culated, e.g. overhanging loads, truck over-
hangs or loading ramps.
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 163).
Active Parking Assist does not assist you park-
ing in spaces at right angles to the direction 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 park-
ing 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 pav-
ing blocks166

To avoid hazardous situations: R
never install snow chains to the front
wheels R
always install snow chains in pairs to the
rear wheels.
! On vehicles with AIRMATIC, you must drive
at raised vehicle level if snow chains have
been mounted. The vehicle may otherwise be
damaged.
! On some tire sizes there is not enough space
for snow chains. To avoid damage to the vehi-
cle or tires, observe the "Wheel and tire com-
binations" section under "Tires and wheels".
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains that have
been specially approved for your vehicle by
Mercedes-Benz, or are of a corresponding
standard of quality. For more information, con-
tact a qualified specialist workshop.
If you intend to mount snow chains, please bear
the following points in mind: R
Snow chains may not be mounted on all
wheel/tire combinations. Permissible wheel-
tire combinations ( Y
page 317).R
Only use snow chains when driving on roads
completely covered by snow. Remove the
snow chains as soon as possible when you
come to a road that is not snow-covered. R
Local regulations may restrict the use of snow
chains. Observe the appropriate regulations if
