R
pay attention to the PARKTRONIC
(Y page 157) 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 vehicle.
Use Active Parking Assist for parking spaces
that are:
R parallel 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 cal- culated, 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 156).
Active Parking Assist does not support you park-
ing in spaces that are parallel to the direction of
travel if:
R the parking space is on a kerb
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 obstacle
which is not clearly defined such as a tree or a
trailer Example: parking symbol
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assist is activated automatically
when driving forwards. The system is opera-
tional at speeds of up to approximately
35 km/ h.While in operation, the system inde-
pendently locates and measures parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
R parallel to the direction of travel
R that are at least 1.5 m wide
R that are at least 1.3 mlonger than your vehicle
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. Active Parking Assist only
displays 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 Active Parking Assist
by pressing the abutton on the multifunc-
tion steering wheel.
A parking space is displayed while you are driv- ing past it, and until you are approximately 15 maway from it.

WARNING
Active Parking Assist merely aids you by inter- vening actively in the steering. There is a risk
of accident if you do not apply the brakes
yourself. Driving systems

Important safety notes G
WARNING
When a load is transported on the roof, the
vehicle's centre of gravity rises and the han-
dling changes. If you exceed the maximum
roof load, the handling as well as steering and braking characteristics are severely affected.
There is a risk of an accident.
Always observe the maximum roof load and
adapt your driving style.
You will find information on the maximum roof
load in the "Technical data" section
(Y page 284).
An incorrectly secured roof carrier or roof load
may become detached from the vehicle. You
must therefore ensure that you observe the roof
carrier manufacturer's installation instructions.

Checking the coolant level G
WARNING
The cooling system is pressurised, particu-
larly when the engine is warm. If you open the cap, you could be scalded if hot coolant
sprays out. There is a risk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Open
the cap slowly to release the pressure.
! The coolant level must only be checked and
corrected when the engine has cooled down
(coolant temperature under 40 †). Checking
the coolant level when the coolant tempera-
ture is over 40 † can lead to damage to the
engine or engine cooling system. X
Park the vehicle on a level surface.
Only check the coolant level when the vehicle
is on a level surface and the drive system has
cooled down.
X Turn the key to position 2in the ignition lock
(Y page 126).
X Check the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
40 †.
X Turn the key to position 0in the ignition lock
(Y page 126).
X Slowly turn cap :anti-clockwise to allow
excess pressure to escape.
X Turn cap :further anti-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.240

must be positioned vertically, directly under
the jacking point of the vehicle.
! Position a suitable jack correctly on the
intended jacking points. If you fail to position the jack correctly, the vehicle may be dam-
aged.
The jacking points for the jack are recesses in
the lower door sill. They can only be seen from
underneath. There is one located behind each
of the front wheel arches and in front of the
rear wheel arches.
Position the jack in the jacking points so that
when viewed from the side, the jack is in the
vertical position.
! Position a suitable jack only on the jacking
points intended for this purpose.
Never position the jack on the high-voltage
battery. Do not jack up the vehicle on the
high-voltage battery. There is otherwise a risk of damaging the high-voltage battery.
Also observe the notes in the "Changing a
wheel" section.
Observe the following when raising the vehi- cle:
R to raise the vehicle, only use the vehicle-spe-
cific jack that has been tested and approved
by Mercedes-Benz. If the jack is used incor-
rectly, 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 per- form maintenance work under the vehicle.
R avoid changing the wheel on uphill and down-
hill 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 drive system 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. X
Using wheel wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts completely. Jacking points
The jacking points are located just behind the
front wheel arches and just in front of the rear
wheel arches (arrows). Changing a wheel
