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 207 )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
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 objects are located above the detection
range, Active Parking Assist may start to steer into the parking space too soon. As a result,
you could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop the vehicle and switch Active
Parking Assist off.
For further information on the detection
range (Y page 207).
Active Parking Assist does not support 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 stone
R you forward park
Active Parking Assist does not support 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 stone
R the parking space appears to be blocked,
for example by foliage or grass paving
blocks
R the range of movement is too small
R the parking space is bordered by an obsta-
cle which is not clearly defined such as a
tree or a trailer Driving systems

This can impair the vehicle's handling char-
acteristics. Adapt your driving style accord-
ingly. Maintain a safe distance. Drive care-
fully.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis- sible speed for your vehicle/trailer combina-
tion.
General notes X
When towing a trailer, set the tyre pressure
on the rear axle of the towing vehicle for a
maximum load; see the tyre pressure table in the fuel filler flap (Y page 356).
Please note that when towing a trailer, PARK-
TRONIC (Y page 206) and Blind Spot Assist
(Y page 222) availability is limited or not avail-
able at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use a trailer with a height-adjustable draw- bar.
You will find fitting dimensions and loads
under "Technical data" (Y page 393).
Driving tips i
Observe the notes on ESP ®
trailer stabi-
lisation (Y page 80).
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. Refer to 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 172).
i This also applies if you have activated
cruise control, SPEEDTRONIC or DIS-
TRONIC 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.
i 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. 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 following compo-
nents. 318

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.
R do not open or close a door or the tailgate
while the vehicle is raised.
R make sure that no persons are present in
the vehicle when the vehicle is raised. Steel wheel with wheel trim

the coolant during operation will be approx-
imately 130 †.
The antifreeze/corrosion inhibitor concentra- tion in the engine cooling system should:
R be at least 50 %. This will protect the engine
cooling system against freezing down to
approximately -37 †.
R not exceed 55 % (antifreeze protection
down to -45 †). Heat will otherwise no t be
dissipated as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor concentrate in accord-
ance with MB Specifications for Service Prod-
ucts 310.1.
i When the vehicle is first delivered, it is fil-
led with a coolant mixture that ensures
adequate antifreeze and corrosion protec-
tion.
i The coolant is checked at every mainte-
nance interval at a qualified specialist
workshop. Windscreen washer system and head-
