Vehicle level Important safety notes
Your vehicle regulates its height
automatically.

All-round level control ensures
the best possible suspension and constant
ground clearance, even with a laden vehicle.
When you drive fast, the vehicle is lowered
automatically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible:
R normal
R raised: the vehicle is raised by about
0.80 in (20 mm) when compared with the
normal level
R lowered: the vehicle is lowered by about
0.40 in (10 mm) when compared with the
normal level180

Suspension tuning General notes
The

electronically controlled damping system
works continuously. This improves driving
safety and ride comfort.
The damping is tuned individually to each
wheel and depends on:
R your driving style, e.g. sporty
R the road surface condition, e.g. bumps
R your individual selection, i.e. sports or
comfort
Your selection remains stored even if you
remove the SmartKey from the ignition lock.
Sports tuning The firmer suspension tuning in Sport mode
ensures even better contact with the road.
Select this mode when employing a sporty
driving style, e.g. on winding country roads. Driving systems

Clean the PARKTRONIC sensors ( Y page 307).
X Switch the ignition back on. The problem may be caused by an external source of radio or
ultrasound waves.
X
See if PARKTRONIC functions in a different location. Active Parking Assist
Important safety notes G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommend parking spaces that
are not suitable for parking. For example,
these might be spaces where parking is
prohibited, driveways, unsuitable surfaces,
etc.
Active Parking Assist measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when

the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you rely solely on Active Parking Assist, you could
cause an accident and injure yourself and
others.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
maneuvering.
G
WARNING
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. In some circumstances, Active
Parking Assist may therefore guide you into
the parking space too early. This may lead to
a collision. For this reason, you should avoid
using Active Parking Assist in such situations. 186

Cup holders
Important safety notes G
WARNING
In order to help prevent spilling liquids on
vehicle
occupants and/or vehicle equipment,
only use containers that fit into the cup
holder. Use lids on open containers and do
not fill containers to a height where the
contents, especially hot liquids, could spill
during braking, vehicle maneuvers, or in an
accident. Liquids spilled on vehicle occupants
may cause serious personal injury. Liquids
spilled on vehicle equipment may cause
damage not covered by the Mercedes-Benz
Limited Warranty.
When not in use, keep the cup holder closed.
An open cup holder may cause injury to you
or others when contacted during braking,
vehicle maneuvers, or in an accident. Keep in mind that objects placed in the cup
holder may come loose during braking,
vehicle maneuvers, or in an accident and be
thrown

around in the vehicle interior. Objects
thrown around in the vehicle interior may
cause an accident and/or serious personal
injury.

not to catch hands or fingers. Be careful that
you do not close the hood on anyone.
Make sure the hood is securely engaged
before driving off. Do not continue driving if
the hood can no longer engage after an

otherwise come loose while the vehicle is in
motion and injure you and/or others. X
Lower the hood and let it fall from a height
of approximately

8 inches (20cm).
X Check that the hood has engaged properly.
If the hood can be raised slightly, it is not

it with a little more force. Engine oil
General notes Depending on the driving style, the vehicle
consumes up to 0.9 US qt

(0.8 liters) of oil
over a distance of 600 miles (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 in 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 about 30 minutes
before carrying out the measurement.
