Rdirt on the camera or if the camera is covered
Rglare on the camera system, e.g. from the sun being low in the sky
Rdarkness

Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensors checked at a qualified specialist
workshop. This also applies to collisions at slow
speeds where there is no visible damage to the
front of the vehicle.
Following damage to the windshield, have the

Function
XTo activate/deactivate: activate or deacti-
vate PRE-SAFE®Brake in the on-board com-
puter (Ypage 196).
If the PRE-SAFE®Brake is not activated, the
æ symbol appears in the multifunction dis-
play.
At or above a speed of approximately 4 mph
(7 km/ h),this function warns you if you rapidly
approach a vehicle in front. An intermittent
warning tone will then sound and the ·dis-
tance warning lamp will light up in the instru-
ment cluster.
XBrake immediately to defuse the situation.
or
XTake evasive action provided it is safe to do
so. PRE-SAFE
®Brake can also brake the vehicle
automatically under the following conditions:
Rthe driver and front passenger have their seat
belts fastened
Rthe vehicle speed is between approximately
4 mph (7 km/h) and 124 mph (200 km/h)
Up to a speed of approximately 44 mph
(70 km/h), PRE-SAFE
®Brake can also detect:
Rstationary objects in the path of your vehicle,
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 56).
If the risk of collision with the vehicle in front
re
mains 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 the PRE-
SAFE
®Brake at any time by:
Rdepressing the accelerator pedal further.
Ractivating kickdown.
Rreleasing the brake pedal.
The braking action of PRE-SAFE®Brake is ended
automatically if:
Ryou maneuver to avoid the obstacle.
Rthere is no longer a risk of collision.
Rthere is no longer an obstacle detected in
front of your vehicle.
Protection against theft
Immobilizer
The immobilizer prevents your vehicle from
being started without the correct SmartKey.
XTo activate with the SmartKey: remove the
SmartKey from the ignition lock.
XTo activate with KEYLESS-GO: switch the
ignition off and open the driver's door.
XTo deactivate: switch on the ignition.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Anyone
can start the engine if a valid SmartKey has been
left inside the vehicle.

iWhen you change lanes, DISTRONIC PLUS
monitors the left lane on left-hand-drive vehi-
cles or the right lane on right-hand-drive vehi-
cles.
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
For further information on deactivating
DISTRONIC PLUS (
Ypage 155).
If DISTRONIC PLUS detects that the vehicle in
front has stopped, it will cause your vehicle to
brake and come to a halt.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever.
When DISTRONIC PLUS is activated, the trans-
mission is shifted automatically to position Pif:
Rthe driver's door is open and the driver's seat
belt is unfastened.
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
Ra system malfunction occurs.
Rthe power supply is not sufficient.
Setting a speed
XPress the cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in1 mphincre-
ments (1 km/hincrements): briefly move
the cruise control lever up :or down ;to
the pressure point.
Every time the cruise control lever is pressed
up : or down ;, the last speed stored is
increased or reduced.
XTo adjust the set speed in5 mphincre-
ments (10 km/hincrements): briefly move
the cruise control lever up :or down ;
beyond the pressure point.
Every time the cruise control lever is pressed
up : or down ;, the last speed stored is
increased or reduced.
iIf you accelerate to overtake, DISTRONIC
PLUS adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Setting a specified minimum distance
You can set the specified minimum distance for
DISTRONIC PLUS by varying the time span
between one and two seconds. With this func-
tion, you can set the minimum distance that
DISTRONIC PLUS keeps to the vehicle in front,
dependent on vehicle speed. You can see this
distance in the multifunction display
(
Ypage 154).
iMake sure that you maintain a sufficient
distance to the vehicle in front and comply
with the minimum distance as required by
law. Adjust the distance to the vehicle in front
if necessary.

HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
Important safety notes
GWARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
!When DISTRONIC PLUS or the HOLD func-
tion is activated, the vehicle brakes automat-
ically in certain situations.
To avoid damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or similar situations:

Rthe area is too small for the vehicle to maneu-
ver into

e.g. a tree, a post or a trailer
Example: detected parking space
:
Detected parking space on the left
;Parking symbol
=Detected parking space on the right
Active Parking Assist is switched on automati-
cally when driving forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the sys-
tem independently locates and measures park-
ing spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparallel or at right angles to the direction of
travel
Rthat are parallel to the direction of travel and
at least 59 in (1.5 m) wide
Rthat are parallel to the direction of travel and
at least 39.5 in (1.0 m)longer than your vehi-
cle
Rthat are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider than
your vehicle
iNote that Active Parking Assist cannot
measure the size of a parking space if it is at
right angles to the direction of travel. You will
need to judge whether your vehicle will fit into the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. By
default, Active Parking Assist only displays park-
ing spaces on the front-passenger side. Parking
spaces on the driver's side are displayed as
soon as t
he turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain switched on until you acknowl-
edge the use of Active Parking Assist by press- ing the
abutton on the multifunction steer-
ing wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft (15 m) away from it.

GWARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
Rthere is a malfunction in the system or in
