= % Unlocks the vehicle
X To unlock centrally: press the%button.
If you do not open the vehicle within approx-
imately 40 seconds of unlocking:
R the vehicle locks again
R protection against theft is reactivated
X To lock centrally: press the&button.
The key centrally locks and unlocks the follow-
ing components: R the doors
R the tailgate
R the fuel filler flap
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 247).
Only when all the components have been
locked, does the optical or acoustic locking con- firmation sound.
If activated in COMAND Online or Audio 20, the
locator lighting also lights up in the dark (see
separate operating instructions).
X To open the tailgate automatically from
outside the vehicle:
press and hold theF
button until the tailgate opens.
Vehicles with KEYLESS-GO or KEYLESS-GO start
function and EASY-PACK tailgate:
X To close the tailgate automatically from
outside the vehicle: if the key is located in the immediate vicinity of the vehicle, press
the
F button on the key.
When the tailgate closes you can then release the button. 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 148).
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 be
outside the vehicle. When locking or unlocking
with KEYLESS-GO, the distance between the key and the corresponding door handle must not be greater than 1 m.
KEYLESS-GO checks whether a valid key is in
the vehicle by periodically establishing a radio
connection between the vehicle and the key.
This happens:
R when starting the engine
R whilst driving
R when the external door handles are touched
R during convenience closing Key

cally if:
R an airbag is deployed or
R the vehicle decelerates rapidly from a speed
of above 70 km/h and comes to a standstill

cally if the vehicle reaches a speed of above
10 km/h again after a full brake application.
i The hazard warning lamps continue to oper-
ate even if the ignition is switched off. Intelligent Light System
General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit the
prevailing driving and weather conditions. It Exterior lighting
117Lights and windscreen wipers Z
offers advanced functions for improved illumi-
nation of the road surface, e.g. depending on the vehicle speed or weather conditions. The sys-
tem includes the active light function, corneringlight function, motorway mode and extended
range foglamps. The system is only active when
it is dark.
You can activate or deactivate the "Intelligent
Light System" function using the on-board com-
puter (Y page 246).
Active light function The active light function is a system that moves
the headlamps according to the steering move- ments of the front wheels. In this way, relevant
areas remain illuminated while you are driving.
This allows you to recognise pedestrians,
cyclists and animals.
Active: when the lights are switched on.
Vehicles with Lane Keeping Assist: the active
light function evaluates the course of the lane in which you are driving and adjusts the light in
advance.
Vehicles with drive program S+(Sport Plus): the
active light function swings the headlamps
inwards and outwards once the drive program is activated. This shows that the sporty light set-
ting is activated. The dynamism of the active
light function is increased. Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the
direction you are turning, enabling better visi-
bility in tight bends, for example. It can only be
activated when the dipped-beam headlamps are
switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the steer- ing wheel.
R if you are driving at speeds between 40 km/h
and 70 km/h and turn the steering wheel.
The cornering light function may remain lit for a
short time, but is automatically switched off
after no more than three minutes.
Cornering light function with roundabout
function:
The cornering light function is activated on both sides before entering a roundabout through an
evaluation of the current GPS position of the
vehicle. It remains active until after the vehicle
has left the roundabout. In this way, pedestrians crossing the road, for example, are illuminated
by your vehicle in good time.
Motorway mode 118
Exterior lightingLights and windscreen wipers
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator pedal.
DISTRONIC PLUS is on and, when activated
for the first time, accepts the current speed or
it adjusts the vehicle's speed to the speed
stored.
Driving with DISTRONIC PLUS Pulling away and driving
X If you want to pull away with DISTRONIC
PLUS: remove your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or X Accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main- tained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program DISTRONIC PLUS supports a sporty driving style
if you have selected the SportorSport Plus
drive program (Y page 158). Acceleration
behind the vehicle in front or to the set speed is then noticeably more dynamic. If you have selected the
Comfortdrive program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-start traffic.
Changing lanes If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving faster than 70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger of
collision
If these conditions are met, your vehicle is accel- erated. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
i Vehicles with COMAND Online:
when you
change lanes, DISTRONIC PLUS monitors the right lane in the case of left-side traffic or the
left lane in the case of right-side traffic.
Vehicles with Audio 20: when you change
lanes, DISTRONIC PLUS monitors the left lane on left-hand-drive vehicles or the right lane onright-hand-drive vehicles.
Vehicles with COMAND Online i
The following function is only available in
vehicles with the Driving Assistance Plus
package.
The function is not operational in all coun-
tries.
DISTRONIC PLUS uses additional information
from your navigation system so that it can adapt to certain traffic situations. This is the case if,
while following a vehicle, DISTRONIC PLUS is
active and you:
R approach or drive around a roundabout
R approach a T-junction Driving systems
