Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC shows you
the distance between your vehicle and an obsta- cle visually and audibly.
Parking Assist PARKTRONIC is only an aid. It is
not a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in range while manoeuvring and parking.
! When parking, pay particular attention to
objects above or below the sensors, such as flower pots or trailer drawbars. Parking Assist
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 of a lorry or a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
! Fold in the ball coupling if the trailer tow
hitch is not required. Parking Assist
PARKTRONIC measures the minimum detec-
tion range to an obstacle from the bumper,
not the ball coupling.
Parking Assist PARKTRONIC is activated auto-
matically when you: R switch on the ignition
R shift the transmission to position D,Ror Non
vehicles with automatic transmission
R release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 18 km/h. It is reactivated at lower
speeds.
Vehicles with a trailer tow hitch: Parking
Assist PARKTRONIC is deactivated for the rear
area when you establish the electrical connec-
tion between your vehicle and a trailer.
Range of the sensors General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
R below the detection range, e.g. persons, ani-
mals or objects
R above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods

sound waves.
X Check to see if Parking Assist PARKTRONIC functions in a different
location. Parking Pilot
General notes Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting a parking space. Park- ing Assist PARKTRONIC is also available
(Y page 177).
i The active braking application is only avail-
able on vehicles with automatic transmission.
Important safety notes Parking Pilot is only an aid. It is not a substitute
for your attention to the immediate surround-
ings. The responsibility for safe manoeuvring
and parking remains with you. Make sure that no
persons, animals or objects are in the manoeu-
vring range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot 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
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tyres.
Parking Pilot may also display spaces not suita- ble for parking, e.g.:
R in a zone where parking or stopping is pro-
hibited
R in front of driveways or entrances and exits
R on unsuitable surfaces 180
Driving systemsDriving and parking

Parking Pilot will detect only parking spaces
which are:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel and
are at least 1.5 m wide
R that are parallel to the direction of travel and
at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 mwider than your vehi-
cle
i Note that Parking Pilot cannot measure the
length of a parking space if it is at right angles to the direction of travel. You will need to
judge whether your vehicle will fit in the park-
ing space.
When driving at speeds below 30 km/h, you will
see parking symbol ;as a status indicator in
the instrument cluster. When a parking space
has been detected, an arrow towards the right or the left also appears. Parking Pilot displays only
parking spaces on the front-passenger side as
standard. Parking spaces on the driver's side
are displayed as soon as the turn signal on the
driver's side is activated. When parking on the
driver's side, this must remain activated until
you confirm the use of Parking Pilot by pressing the a button on the multifunction steering
wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 15 m
away from it.

WARNING
If you leave the vehicle when it is only being
braked by Parking Pilot, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
R the battery is disconnected
R the vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident. Before leaving the vehicle, always secure it
against rolling away.

Parking Pilot is ended, you must steer and brake again yourself. Parking Assist PARKTRONIC is
still available.
Parking tips:
R The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front of and behind it and the conditions of the location. It
may be the case that Parking Pilot guides you
too far into a parking space, or not far enough
into it. In some cases, it may also lead you
across or onto the kerb. If necessary, you
should abort the parking procedure with Park-
ing Pilot.
R You can also preselect transmission position
D. The vehicle redirects and does not drive as
far into the parking space. Should the trans-
mission change take place too early, the park-
ing procedure will be cancelled. A sensible
parking position can no longer be achieved
from this position.
Exiting a parking space In order that Parking Pilot can support you when
exiting the parking space:
R you need to have parked using Parking Pilot
R the border of the parking space must be high
enough at the front and the rear. A kerb stoneis too small, for example.
R the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is manoeuvred into the parking
space.
R a manoeuvring distance of at least 1.0 mmust
be available.
Parking Pilot can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel using the Park-
ing Pilot

WARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is a risk of an accident.
Always steer, apply the brakes or accelerate
the vehicle yourself, especially if Lane Keep-
ing Assist alerts you.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of an acci-
dent nor override the laws of physics. Lane
Keeping Assist cannot take into account road,
weather or traffic conditions. Lane Keeping
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
lane.
Lane Keeping Assist does not keep your vehicle
in its lane.
The system may be impaired or may not function in the following situations:
R Poor visibility, e.g. due to insufficient illumi-
nation of the road, or due to snow, rain, fog or
spray
R Glare, e.g. from oncoming traffic, the sun or
reflection from other vehicles (e.g. if the road surface is wet)
R The windscreen is dirty, misted up, damaged
or covered, for instance by a sticker, in the
vicinity of the camera
R No or several, unclear lane markings are pres-
ent for one lane, e.g. in a construction area
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 so small
that the lane markings 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 highly variable shade conditions on
the roadway
Activating Lane Keeping Assist
X Activate Lane Keeping Assist using the on-
board computer; to do so, select Standard
Standard or
Adaptive
Adaptive (Ypage 209).
If you drive at speeds above 60 km/h and lane markings are detected, the lane markings in
the assistance graphics display (Y page 208)
are shown in green. If
Standard
Standard is selected, no warning vibration
occurs if:
R You have switched on the turn signal. In this
event, the warnings are suppressed for a cer-
tain period of time.
R A driving safety system such as ABS, BAS or
ESP ®
engages.
When Adaptive
Adaptive is selected, no warning vibra-
tion occurs if:
R You have switched on the turn signal. In this
case, the warnings are suppressed for a cer-
tain period of time
R A driving safety system such as ABS, BAS or
ESP ®
engages
R You accelerate hard, e.g. kickdown
R You brake hard
R You steer actively, e.g. swerve to avoid an
obstacle or change lane quickly
R You cut the corner on a sharp bend
To ensure that you are warned only when nec-
essary and in good time if you cross the lane
marking, the system detects certain conditions
and warns you accordingly.
The warning vibration occurs earlier in the fol-
lowing situations:
R You approach the outer lane marking on a
bend
R The road has very wide lanes, e.g. a motorway
R The system detects solid lane markings
The warning vibration occurs later in the follow- ing situations:
R The road has narrow lanes
R You cut the corner on a bend Towing a trailer
Important safety notes
G
WARNING
You could lose control of the vehicle/trailer
combination if it begins to swerve. The vehi-
cle/trailer combination could even overturn.
There is a risk of an accident.
On no account should you attempt to
straighten out the vehicle/trailer combina-
tion by increasing speed. Decrease your
speed and do not countersteer. Brake if nec-
essary. 194
Towing a trailerDriving and parking

not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on towing a trailer
General notes Trailer towing is not possible on the following
models:
R CLA 180 d BlueEFFICIENCY Edition
R CLA 250 Sport
R CLA 250 Sport 4MATIC
R Mercedes‑AMG CLA 45 4MATIC
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for the max-
imum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 313).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all.
R Parking Assist PARKTRONIC (Y page 177)
R Blind Spot Assist (Y page 192)
The height of the ball coupling changes with the
load of the vehicle. If necessary, use a trailer
with a height-adjustable drawbar.
You will find fitting dimensions and loads under "Technical data" (Y page 334).
Driving tips Observe the notes on ESP
®
trailer stabilisation
(Y page 72).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the legally prescri-
bed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See the "Technical data"
section to find out whether this applies to your
vehicle. If you utilise any of the added maximum rear axle load when towing a trailer, the vehicle/
trailer combination may not exceed a maximum speed of 100 km/h for reasons concerning the
operating permit. This also applies in countries
in which the permissible maximum speed for
vehicle/trailer combinations is above
100 km/h. When towing a trailer, your vehicle's handling
characteristics will be different to when driving
without a trailer and the vehicle will consume
more fuel.
Shift into a lower gear in good time on long and steep downhill gradients. For vehicles with auto-
matic transmission, you need to have selected
manual drive program M(Y page 150).
This also applies if you have activated cruise
control, SPEEDTRONIC or Distance Pilot
DISTRONIC.
This will use the braking effect of the engine, so
less braking will be required to maintain the
vehicle speed. This relieves the load on the
brake system and prevents the brakes from
overheating and wearing too quickly. If you need additional braking, depress the brake pedal
repeatedly rather than continuously.
Briefly depressing the accelerator pedal on
downhill gradients while the manual drive pro-
gram Mis temporarily activated (vehicles with
automatic transmission): the automatic trans-
mission may switch back to the last active auto-
matic drive program Eor S. The automatic trans-
mission may shift to a higher gear. This can
reduce the engine's braking effect.
Driving tips R
Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from a standstill, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances
X Do not countersteer
X Brake, if necessary 196
