Tips for driving with DISTRONIC PLUS General notes
Pay particular attention in the following traffic
situations:
R Cornering, going into and coming out of a
bend
R Vehicles traveling on a different line
R Other vehicles changing lanes
R Narrow vehicles
R Obstructions and stationary vehicles
R Crossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated. 208
Driving systemsDriving and parking
Crossing vehicles
DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally.
DISTRONIC PLUS with Steering Assist General notes
DISTRONIC PLUS Steering Assist helps you
to drive in the middle of the lane by means of
moderate steering interventions at speeds of
0 - 125 mph (0 - 200 km/h).
DISTRONIC PLUS Steering Assist monitors
the area in front of your vehicle by means of
camera system 0043at the top of the
windshield.
At speeds of more than 37 mph (60 km/h),
DISTRONIC PLUS Steering Assist focuses on
lane markings that are present.
At speeds of 0 - 37 mph (0 - 60 km/h),
DISTRONIC PLUS Steering Assist focuses on
the vehicle in front, taking into account lane markings, e.g. when following vehicles in a
traffic jam.
DISTRONIC PLUS must be active in order for
the function to be available.
Important safety notes
If you fail to adapt your driving style,
DISTRONIC PLUS Steering Assist can neither
reduce the risk of an accident nor override the
laws of physics. DISTRONIC PLUS Steering
Assist cannot take into account road,
weather or traffic conditions. DISTRONIC
PLUS Steering Assist 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.
DISTRONIC PLUS Steering Assist does not
detect road and traffic conditions. If you are
following a vehicle which is driving towards
the edge of the road, your vehicle could come
into contact with the curb or other road
boundaries. In the case of deviations in road
markings, beware of other road users, e.g.
cyclists, that are in the direct vicinity of your
vehicle.
Obstacles such as building site huts on the
lane or projecting out into the lane are not
detected.
An inappropriate steering intervention, e.g.
after intentionally driving over a lane marking,
can be corrected at any time if you steer
slightly in the opposite direction.
DISTRONIC PLUS Steering Assist cannot
continuously keep your vehicle in lane. In
some cases, the steering intervention is not
sufficient to bring the vehicle back to the lane.
In such cases, you must steer the vehicle
yourself to ensure that it does not leave the
lane. 210
Driving systemsDriving and parking
The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when 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
markings for a lane, e.g. in areas with road
construction work
R the lane markings are worn away, dark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or
merge
R the road is narrow and winding
R there are strong shadows cast on the lane
Pay attention also to the important safety
notes for DISTRONIC PLUS (Y page 202).
The steering interventions are carried out
with a limited steering moment. The system
requires the driver to keep his hands on the
steering wheel and to steer himself.
If you do not steer yourself or if take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you
with a visual warning. A steering wheel
symbol appears in the multifunction display.
If you have still not started to steer and have
not taken hold of the steering wheel after five
seconds, a warning tone also sounds to
remind you to take control of the vehicle.
DISTRONIC PLUS Steering Assist is then
switched to passive. DISTRONIC PLUS
remains active. The system is switched to passive and no
longer assists you by performing steering
interventions if:
R
you actively change lane
R you use a turn signal
R take your hands off the steering wheel or
do not steer for a prolonged period of time
i After you have finished changing lanes,
DISTRONIC PLUS Steering Assist is
automatically active once more.
DISTRONIC PLUS Steering Assist does not
provide assistance:
R on very sharp corners
R if no roadside markings or no clear roadside
markings have been detected
R if the vehicle in front is not detected at
speeds below 37 mph (60 km/h)
R in tire run-flat mode

When leaving the vehicle, it can still roll away
despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply.
R the HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
R the electrical system in the engine
compartment, the battery or the fuses have
been tampered with.
R the battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
the HOLD function and secure the vehicle
against rolling away.
Further information on deactivating the HOLD
function ( Ypage 213).
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
R when towing the vehicle
R in the car wash
Activation conditions You can activate the HOLD function if all of
the following conditions are fulfilled:
R the vehicle is stationary.
R the engine is running or if it has been
automatically switched off by the ECO
start/stop function.
R the driver's door is closed or your seat belt
is fastened.
R the electric parking brake is released.
R the transmission is in position D,Ror N.

Crosswind driving assistance The crosswind stabilization operates by
changing wheel loads through adjusting the

Active Body Control (ABC) Vehicle level
All vehicles except AMG vehicles:
depending on the vehicle level that has been
set, the vehicle automatically adjusts its
height dependent on the current speed. The
vehicle is lowered by up to 0.6 in (15 mm) as
the speed increases. As the speed is reduced,
the vehicle is raised up to the set vehicle
height.
AMG vehicles: depending on the vehicle
level that has been selected, the vehicle
automatically adjusts its height dependent on
the current speed. The vehicle is lowered by
up to 0.4 in (10 mm) below the normal level
as the speed increases. As the speed is
reduced, the vehicle is raised up to the set

General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking and when
exiting a parking space. You may also use
PARKTRONIC (Y page 218).
Important safety notes Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking 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
Parking Assist parking procedure.
! If unavoidable, you should drive over
obstacles 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
parking, for example:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces Driving systems
