Diagnostics connection
The diagnostics connection is used for con-necting diagnostic equipment at a qualifiedspecialist workshop.
GWARNING
If you connect equipment to a diagnostics
connection in the vehicle, it may affect the
operation of vehicle systems. As a result,
the operating safety of the vehicle could be
affected. There is a risk of an accident.
Only connect equipment to a diagnostics
connection in the vehicle, which is approved
for your vehicle by Mercedes-Benz.
GWARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardizes the oper-
ating and road safety of the vehicle. There is
a risk of an accident.
Stow all objects securely in the vehicle so
that they do not get into the driver's foot-
well. When using floormats or carpets, make
sure that they are properly secured so that
they do not slip or obstruct the pedals. Do
not place several floormats or carpets on
top of one another.
!If the engine is switched off and equip-ment on the diagnostics connection is used,the starter battery may discharge.
Connecting equipment to the diagnostics con-nection can lead to emissions monitoringinformation being reset, for example. This maylead to the vehicle failing to meet the require-ments of the next emissions test during themain inspection.

28Operating safety
Introduction

Up to a speed of approximately 44 mph(70 km/h), Active Brake Assist with cross-traf-fic function may react to:
Rstationary objects in the path of your vehi-cle, e.g. stopped or parked vehicles
Rpedestrians in the path of your vehicle
iIf there is an increased risk of a collision,preventive passenger protection measures
(PRE-SAFE®) are triggered (Ypage 55).
If the risk of collision with the vehicle in frontremains and you do not brake, take evasiveaction or accelerate significantly, the vehiclemay perform automatic emergency braking, upto the point of full brake application. Auto-matic emergency braking is not performeduntil immediately prior to an imminent acci-dent.
You can prevent the intervention of ActiveBrake Assist with cross-traffic function at anytime by:
Rdepressing the accelerator pedal further
Ractivating kickdown
Rreleasing the brake pedal
The braking application of Active Brake Assistwith cross-traffic function is ended automati-cally if:
Ryou maneuver to avoid the obstacle
Rthere is no longer a risk of collision
Ran obstacle is no longer detected in front ofyour vehicle
STEER CONTROL
General information
STEER CONTROL helps you by transmitting anoticeable steering force to the steering wheelin the direction required for vehicle stabiliza-tion.
This steering assistance is provided in particu-lar if:
Rboth right wheels or both left wheels are ona wet or slippery road surface when youbrake
Rthe vehicle starts to skid
Important safety notes
iObserve the "Important safety notes" sec-tion (Ypage 60).
No steering support is provided from STEERCONTROL, if:
RESP®is deactivated
RESP®is malfunctioning
Rthe steering is faulty
If ESP®is malfunctioning, you will be assistedfurther by the electrical power steering.

Side windows
Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side
window and the door frame as the side win-
dow moves. There is a risk of injury.
Make sure that nobody touches the side
window during the opening procedure. If
somebody becomes trapped, release the
switch or pull the switch to close the side
window again.
GWARNING
While closing the side windows, body parts
in the closing area could become trapped.
There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody
becomes trapped, release the switch or
press the switch to open the side window
again.
GWARNING
If children operate the side windows they
could become trapped, particularly if they
are left unsupervised. There is a risk of
injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle.
Never leave children unsupervised in the
vehicle.
Side window reversing feature
The front side windows are equipped with anautomatic reversing feature. If a solid objectblocks or restricts the upward movement ofone of the front side windows during the clos-ing process, the side window opens againautomatically. During the manual closing proc-ess, the side window only opens again auto-matically after the corresponding switch isreleased. However, the automatic reversingfeature is only an aid and does not relieve youof the responsibility of paying attention whenclosing a side window.
GWARNING
The reversing feature does not respond:
Rto soft, light and thin objects, e.g. fingers
Rover the last 1/6 in (4 mm) of the closing
movement
Rwhile adjusting
Rwhen closing the side window again man-
ually immediately after automatic revers-
ing
This means that the reversing feature can-
not prevent someone being trapped in these
situations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the
switch to open the side window again.

Problems with the side windows
GWARNING
If you close a side window again immediately after it has been blocked or reset, the side win-
dow closes with increased or maximum force. The reversing feature is then not active. Parts of
the body could be trapped in the closing area in the process. This poses an increased risk of
injury or even fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process,
release the switch or push the switch again to reopen the side window.
ProblemPossible causes/consequences andPPSolutions
A side window cannotbe closed because it isblocked by objects, e.g.leaves in the windowguide.
XRemove the objects.
XClose the side window.
A side window cannotbe closed and you can-not see the cause.
If a side window is obstructed during closing and reopens againslightly:
XImmediately after the window blocks, pull the correspondingswitch again until the side window has closed.The side window is closed with increased force.
If a side window is obstructed again during closing and reopensagain slightly:
XImmediately after the window blocks, pull the correspondingswitch again until the side window has closed.The side window is closed without the automatic reversing fea-ture.
The side windows can-not be opened or closedusing the convenienceopening/closing fea-ture.

XCheck the SmartKey battery (Ypage 77) and replace it if neces-sary (Ypage 77).
Roof
Important safety notes
GWARNING
If you do not fully open/close the soft top,
the soft-top hydraulics depressurize after a
short time. This causes the soft top to lower
unexpectedly and may cause you or others
to be trapped. There is a risk of injury.
Always open or close the soft top com-
pletely.
GWARNING
Closing the roof manually is a complicated
and technically demanding procedure, which
requires a lot of strength. You or others can
become trapped. There is a risk of injury.
Only have the soft top closed manually at a
qualified specialist workshop.
!Never sit on the rear compartment trim orstow heavy objects there. You will otherwisedamage the roof and rear compartment trimof the vehicle.

Switching the seat heating on/off
Switching on/off
GWARNING
Repeatedly switching on the seat heating
can cause the seat cushion and backrest
pads to become very hot. The health of per-
sons with limited temperature sensitivity or
a limited ability to react to high tempera-
tures may be affected or they may even suf-
fer burn-like injuries. There is a risk of injury.
Therefore, do not switch the seat heating on
repeatedly.
!When the seat heating is switched on, theseat surface can be damaged as a result ofobjects being placed on the seats, for exam-ple, seat cushions, child seats and protec-tive covers not approved by Mercedes-Benz.
Ensure that there are no objects on the seatsurface when the seat heating is switchedon.

Problems with the seat heating
ProblemPossible causes/consequences andPPSolutions
The seat heating hasswitched off prema-turely or cannot beswitched on. The vehi-cle's electrical systemvoltage is too lowbecause too many elec-trical consumers areswitched on.
Switch off electrical consumers that you do not need, such as therear window defroster or interior lighting.
Once the battery is sufficiently charged, switch on the seat heatingagain.
