exiting a parking space. You may also use
PARKTRONIC (
Y page 183). When
PARKTRONIC is switched off, Active Parking
Assist is also unavailable.
Parking tips:
R pay attention to the PARKTRONIC
(Y page
185) 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 canceled.
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 or an emergency spare wheel are
mounted.
R make sure that the tire pressures are
always correct. This has a direct influence
on the parking characteristics of the
vehicle.
Parking Detecting a parking space
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. 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. Example: detected parking space
Active Parking Assist is switched on
automatically when driving forwards. The
system is operational at speeds of up to
approximately
22 mph (35 km/h

). While in
operation, the system independently locates
and measures parking spaces on both sides
of the vehicle. At a speed below 19 mph
(30 km/h), you will see parking symbol ; as
the status indicator in the instrument cluster.
If a parking space has been detected, an
arrow pointing to the right = or left : is also
displayed.
By default, Active Parking Assist only displays
parking spaces on the front-passenger side.
Parking spaces on the driver's side are
displayed as soon as the turn signal on the
driver's side is activated. If you wish to park
in a space on the driver's side, the indicator
on the driver's side must remain on. The turn
signal must remain switched on until you
acknowledge the use of Active Parking Assist Driving systems
187Driving and parking Z

by pressing the
a button on the
multifunction steering wheel.
Active Parking
Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 59 in (1.5 m) wide
R that are at least 40 in (1.0 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Backing up into the parking space G
WARNING
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation. In some cases the vehicle
will also take you onto sections of the
oncoming lane

during the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please
note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Read the information on qualified
specialist workshops: ( Y page 31).Important safety notes
G
WARNING
The driver's concentration must always be
directed primarily at road traffic.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when

traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers
a distance of 44 feet (approximately 14 m) per
second. G
WARNING
No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
R speed
R outside temperature
R warning/indicator lamps
R malfunction/warning messages
R failure of any systems
Driving characteristics may be impaired. If
you must continue to drive, do so with added
caution. Contact an authorized Mercedes-
Benz Center as soon as possible. G
WARNING
Malfunction and warning messages are only
displayed for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance services and safety checks
performed on

the vehicle. Bring the vehicle to
an authorized Mercedes-Benz Center to
address the malfunction and warning
messages. G
WARNING
All
categories of messages contain important
information which should be taken note of
and, where a malfunction is indicated,
addressed as soon as possible at an
authorized Mercedes-Benz Center.
Failure to repair the condition noted may
cause damage

not covered by the Mercedes-
Benz Limited Warranty, or result in property
damage or personal injury.

WARNING
Driving when your engine is overheated can
cause some

fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.

! Do not drive in the overrevving range, as
this could damage the engine.

G
WARNING
The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point

do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.
The outside temperature display is in the
multifunction display ( Y page 208).
