Active Parking Assist may also display spaces
not suitable for parking, e.g.:
R parking or stopping prohibitions
R in front of driveways or entrances and exits
R unsuitable surfaces
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space
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 210 )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 cancelled
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 fitted
R make sure that the tyre pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel.
R on straight roads, not bends
R on the same level as the road, e.g. not on
the pavement
For vehicles with the trailer tow hitch folded
out, the minimum length for parking spaces is slightly longer.
If you have attached a trailer to your vehicle,
you should not use Active Parking Assist.
Once the electrical connection is established between your vehicle and the trailer, Active
Parking Assist is no longer available.
PARKTRONIC is deactivated for the rear area.
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
This could cause a collision. 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 209).
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 kerb
R you forward park
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 kerb
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
manoeuvre into
R the parking space is bordered by an obsta-
cle, e.g. a tree, a post or a trailer Driving systems

Notes on towing a trailer
General notes Trailer towing is not permissible on the fol-
lowing models:
R
A 250 Sport
R A 250 Sport 4MATIC
R Mercedes‑AMG A 45 4MATIC
R A 180 d BlueEFFICIENCY Edition
R Vehicles with AMG Line
When towing a trailer, set the tyre pressure on the rear axle of the towing vehicle for the
maximum load. Further information on the
tyre pressure table in the fuel filler flap
(Y page 362).
Please note that when towing a trailer, the
following driving systems have limited avail-
ability or are not available at all.
R PARKTRONIC (Y page 209)
R Blind Spot Assist (Y page 226)
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 405).
Driving tips Observe the notes on ESP
®
trailer stabilisa-
tion (Y page 76).
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 max-imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Benz vehicles, the max-
imum 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 in comparison
to when driving without a trailer and it will
consume more fuel.
Change into a lower gear in good time on long
and steep downhill gradients. For vehicles
with automatic transmission, you need to
have selected manual drive program M
(Y page 177).
This also applies if you have activated cruise
control, SPEEDTRONIC or DISTRONIC PLUS.
This will use the braking effect of the engine,
so less braking will be required to maintain
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
program Mis temporarily activated (vehicles
with automatic transmission): the automatic
transmission may switch back to the last
active automatic drive program Eor S. The
automatic transmission may shift to a higher
gear. This can reduce the engine's braking
effect.
Driving tips If the trailer swings from side to side:
X Do not accelerate.
X Do not countersteer.
X Brake if necessary.
R Maintain a greater distance to the vehicle in
front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from a standstill refer to sea
level. When driving in mountainous areas, Towing a trailer

General notes Depending on your driving style, the vehicle
consumes up to 0.8 litres of oil per 1,000 km.
The oil consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds.
Depending on the engine, the oil dipstick may be installed at a different location. When checking the oil level:
R park the vehicle on a level surface
R the engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
R if the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly, wait approximately
30 minutes before carrying out the meas-
urement

stick G
WARNING
Certain components in the engine compart-
ment could be very hot, e.g. the engine, the
radiator and parts of the exhaust system.
There is a risk of injury when accessing the
engine compartment.
As far as possible, allow the engine to cool
down and only touch the components descri- bed in the following. 324
Engine compartmentMaintenance and care

Securing the vehicle against rolling
away
If your vehicle is equipped with a wheel chock,
it can be found in the tyre-change tool kit
(Y page 339).
The folding wheel chock is an additional
securing measure to safeguard the vehicle
from rolling away, for example when changing
a wheel.
X Fold both plates upwards :.
X Fold out lower plate ;.
X Guide the lugs on the lower plate fully into
the openings in base plate =.X
Place chocks or other suitable items under
the front and rear of the wheel that is diag-
onally opposite the wheel you wish to
change.
Raising the vehicle G
WARNING
If you do not position the jack correctly at the appropriate jacking point of the vehicle, the jack could tip over with the vehicle raised.
There is a risk of injury.
Only position the jack at the appropriate jack-
ing point of the vehicle. The base of the jack
must be positioned vertically, directly under
the jacking point of the vehicle.
Observe the following when raising the
vehicle:
R to raise the vehicle, only use the vehicle-
specific jack that has been tested and
approved by Mercedes-Benz. If the jack is
used incorrectly, it could tip over while the vehicle is raised.
R the jack is designed only to raise and hold
the vehicle for a short time while a wheel
is being changed. It is not permissible to
use it to perform maintenance work under
the vehicle.
R avoid changing the wheel on uphill and
downhill slopes.
R before raising the vehicle, safeguard it from
rolling away by applying the parking brake
and positioning wheel chocks. Do not
release the parking brake while the vehicle
is raised.
R the jack must be placed on a firm, flat and
non-slip surface. On a loose surface, a
large, flat load-bearing underlay must be
used. On a slippery surface, a non-slip
underlay must be used, e.g. rubber mats.
R do not use wooden blocks or similar
objects as a jack underlay. Otherwise, the
jack will not be able to achieve its load-
bearing capacity due to the restricted
height.
R make sure that the distance between the
underside of the tyres and the ground does
not exceed 3 cm.
R never place your hands or feet under the
raised vehicle.
R do not lie under the vehicle.
R do not start the engine when the vehicle is
raised. Changing a wheel
