Driving safetysystems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lockBrakingSystem)
(Ypage 61)
RBAS (BrakeAssistSystem) (Ypage 62)
RCOLLISION PREVENTION ASSIST (distance
warning function and adaptive Brake
Assist) (Ypage 62)
RESP®(ElectronicStabilityProgram)
(Ypage 65)
REBD (ElectronicBrake forceDistribution)
(Ypage 69)
RADAPTIVE BRAKE (Ypage 69)
RSTEER CONTROL (Ypage 69)
Important safety notes
If you fail to adapt yourdriving style or
become distracted, the driving safety
systems can neither reduce the risk of
accident nor override the laws of physics.
Driving safety systems are merely aids
designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in
good time. Always adapt yourdriving style to
suitthe prevailing road, weather and traffic
conditions and maintainasafe distance from
the vehicle in front. Drive carefully.
iThe driving safety systems described only
work as effectively as possible when there
is adequate contact between the tires and
the road surface. Pay particular attention
to the informationregarding tires,
recommended minimum tire tread depths
etc.inthe "Wheels and tires" section
(Ypage 312).
In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.
ABS (Anti-lockBraking System)
General information
ABS regulates brake pressure in such a way
thatthe wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
TheABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
Important safety notes
iObserve the "Important safety notes"
section for driving safety systems
(Ypage 61).

68Driving safety systems
Safety

If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
XShift the transmission to positionN.
Drive particularly carefully on slippery road
surfaces.Avoid sudden acceleration, steering
and braking maneuvers. Do not use the cruise
control or DISTRONIC PLUS.
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Changes in the outside temperature are
displayed after a short delay.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges. You
should pay special attention to road
conditions when temperatures are around
freezing point.
iFor more information on driving with
snow chains, see (Ypage 315).
Driving systems
Cruise control
General notes
Cruise control maintains a constant road
speed for you.Itbrakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select a low gearin
good time. For this, you will need to have
selected manual drive program
M(Ypage 148). By doing so, you will make
use of the braking effect of the engine, This
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an
accident nor override the laws of physics.
Cruise control cannot take into account the
road, traffic and weather conditions. Cruise
control 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.
Do not use cruise control:
Rin road and traffic conditions which do not
allow you to maintain a constant speed e.g.
in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.

multifunction display.
iIf RACE START is used repeatedly within
a short period of time, it is only available
again after the vehicle has been driven a
certain distance.
4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are
permanently driven. Together with ESP®, it
improves the traction of your vehicle
whenever a drive wheel spins due to
insufficientgrip.
If you fail to adapt yourdriving 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:
ROnly depress the accelerator pedal as far
as necessary when pulling away.
RAccelerate 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 vehicle with all wheels in full
contact with the ground.
iIn 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.

Driving and parking

Parking tips:
ROn narrow roads, drive as close to the
parking space as possible.
RParking spaces that are littered or
overgrown might be identified or measured
incorrectly.
RParking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
RSnowfall or heavy rain may lead to a parking
space being measured inaccurately.
RPay attention to the PARKTRONIC
(Ypage 176) warning messages during the
parking procedure.
RYou can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
RWhen transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
RNever use Active Parking Assist when snow
chains are installed.
RMake sure that the tire pressures are
always correct. This hasadirectinfluence
on the parking characteristics of the
vehicle.
Use Active Parking Assist for parking spaces:
Rthatare parallel or at right-angles to the
direction of travel
Rthat are on straight roads, not bends
Rthat 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.
GWARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist.
For further information on the detection
range (Ypage 175).
Active Parking Assist does not support you
with parking spaces at right-angles to the
direction of travel if:
Rtwo parking spaces are located directly
next to one another
Rthe parking space is directly next to a low
obstacle such as a low curb
Ryou park forwards
Active Parking Assist does not support you
with parking spaces that are parallel or at
right-angles to the direction of travel if:
Rthe parking space is onacurb
Rthe parking space is apparently blocked,
for example by foliage or grass paving
