If the risk of a collision with the vehicle in front
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking up
to the point of full brake application. Automatic
emergency braking is not performed until imme- diately prior to an imminent accident.
You can prevent the intervention of Active Brake Assist with cross-traffic function at any time by:
R depressing the accelerator pedal further
R activating kickdown
R releasing the brake pedal
The braking application of Active Brake Assist
with cross-traffic function is ended automati-
cally if:
R you manoeuvre to avoid the obstacle
R there is no longer a risk of collision
R there is no longer an obstacle detected in
front of your vehicle STEER CONTROL
General notes STEER CONTROL helps you by transmitting a
noticeable steering force to the steering wheel
in the direction required for vehicle stabilisation.
This steering support is provided in particular if:
R both right wheels or both left wheels are on a
wet or slippery road surface when you brake
R the vehicle starts to skid
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page 62).
No steering support is provided from STEER
CONTROL, if:
R ESP ®
is deactivated
R ESP ®
is malfunctioning
R the steering is faulty
If ESP ®
is malfunctioning, you will be assisted
further by the electrical power steering. Protection against theft

When unlocking, the turn signals flash once.
When locking, they flash three times.
You can also set an audible signal to confirm
that the vehicle has been locked. The audible
signal can be activated or deactivated using the
on-board computer (Y page 211).
When it is dark, the surround lighting also comes
on if it is activated in the on-board computer
(Y page 210). KEYLESS-GO
General notes Bear in mind that the engine can be started by
any of the vehicle occupants if there is a KEY-
LESS-GO key in the vehicle (Y page 134).
Locking and unlocking centrally You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you need to carry the
key with you. You can combine the KEYLESS-GO
functions with the functions of a conventional
key. Unlock the vehicle by using KEYLESS-GO,
for instance, and lock it using the &button
on the key.
The driver's door and the door at which the han- dle is used must both be closed. The key must beoutside the vehicle. When locking or unlocking
with KEYLESS-GO, the distance between the keyand the corresponding door handle must not be
greater than 1 m.
A check which periodically establishes a radio
connection between the vehicle and the key
determines whether a valid key is in the vehicle. This occurs, for example:
R when starting the engine
R whilst driving
R when using HANDS-FREE ACCESS
R when the external door handles are touched X
To unlock the vehicle: touch the inner sur-
face of the door handle.
X To lock the vehicle: touch sensor surface :
or ;.
Make sure that you do not touch the inner
surface of the door handle.
X Convenience closing feature: touch
recessed sensor surface ;for an extended
period.
For further information on the convenience
closing feature (Y page 91).
Deactivating and activating If you do not intend to use a key for an extended
period of time, you can deactivate the KEYLESS-
GO function of the key. The key will then use very
little power, thereby conserving battery power.
For the purposes of activation or deactivation,
the vehicle does not have to be nearby.
X To deactivate: press the&button on the
key twice in rapid succession.

key flashes twice briefly and lights up once,
then KEYLESS-GO is deactivated.

WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The boot lid swings upwards when opened.
Therefore, make sure that there is sufficient
clearance above the boot lid.
! Only close the boot once the roof is lowered
completely. Otherwise, you could damage the roof.
The opening dimensions of the boot lid can be
found in the "Vehicle data" section
(Y page 327).
When the roof is open, you can use the loading
aid to raise the folded roof in the boot to make
loading easier (Y page 264). The boot separator
opens automatically.
You can unlock the boot lid when the vehicle is
stationary and the roof is fully opened or closed.
Do not leave the key in the boot. You could oth- erwise lock yourself out.
The boot lid can be:
R opened and closed from outside
R opened and closed automatically from out-
side (vehicles with boot lid remote closing
feature)
R opened and closed automatically from inside
(vehicles with boot lid remote closing feature)
R opened, closed or stopped during operation
without the use of your hands (vehicles with
KEYLESS-GO and HANDS-FREE ACCESS)
R locked separately
R unlocked with the emergency key element
Stow luggage or loads preferably in the boot. Boot lid reversing function
The boot lid is equipped with an automatic
reversing function. It reacts if a solid object
obstructs or restricts the boot lid during the
closing procedure. The boot lid opens again
automatically. The automatic reversing function
is only an aid and is not a substitute for your
attentiveness to the boot lid while it is closing. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. fingers
R over the last 8 mm of the closing path
The reversing feature cannot prevent some-
one being trapped in these situations in par-
ticular. There is a risk of injury.
When closing make sure that no body parts
are in the closing area.
If someone is trapped:
R press the Fbutton on the key or
R press the remote operating switch on the
driver’s door, or
R press the closing or locking button on the
boot lid, or

Problems with the side windows
G
WARNING
If you close a side window again immediately after it has been blocked or reset, the side window
closes with increased or maximum force. The reversing function 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, releasethe switch or push the switch again to reopen the side window. Problem

guide. X
Remove the objects.
X Close the side window. A side window cannot be
closed and you cannot
see the cause. If a side window is obstructed during closing and reopens again
slightly:
X Immediately after the window blocks, pull the corresponding switch
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 reopens again slightly:

WARNING
If you do not fully open/close the soft top, the soft-top hydraulics depressurise after a short time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely. G
WARNING
Closing the roof manually is a complex, tech-
nically challenging procedure that requires
considerable effort during certain phases.
You or others could be trapped while perform- ing this task. 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 or
stow heavy objects there. You will otherwise
damage the roof and rear compartment trim
of the vehicle.
! Do not forget that the weather can change
abruptly. Make certain that the roof is closed when you leave the vehicle. The vehicle elec-tronics can be damaged if water enters the
vehicle interior.
! When opening and closing the roof, make
sure that:
R there is sufficient upward clearance, as the
roof swings upwards.
R there is sufficient clearance behind the
vehicle, as the boot lid swings backwards

When opening or closing the roof, body parts could be trapped by, for example, the roof
mechanism, boot lid or side windows. There is a risk of injury.
When raising or lowering the roof, make sure
that no body parts are in the vicinity of moving
components. If someone becomes trapped,
release the button.
For safety reasons, the roof can only be opened
or closed when the vehicle is stationary.
! Operating the roof while pulling away:
R Observe the following traffic carefully.
R Do not drive faster than 40 km/h.
R Avoid abrupt braking and swerving
manoeuvres.
Do not operate the roof when cornering, driv-
ing on uneven surfaces or during strong
winds. The vehicle could otherwise be dam-
aged.
