Make sure that the activation conditions
are met.
X Depress the brake pedal.
X Quickly depress the brake pedal further
until 00D9 appears in the multifunction dis-
play.
The HOLD function is activated. You can
release the brake pedal.
i If depressing the brake pedal the first
time does not activate the HOLD function,
wait briefly and then try again.
Deactivating the HOLD function The HOLD function is deactivated automati-
cally if:
R you accelerate and the transmission is in
position Dor R.
R the transmission is in position P.
R you depress the brake pedal again with a
certain amount of pressure until 00D9dis-
appears from the multifunction display.
R you activate DISTRONIC PLUS.
When the HOLD function is activated in vehi-
cles with an automatic transmission, the
transmission is shifted automatically to posi- tion P if:
R the driver's door is open and the driver's
seat belt is unfastened.
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/
stop function.
R the hood is opened.
R a system malfunction occurs.
R the power supply is not sufficient.
The horn will also sound at regular intervals if
the HOLD function is activated and you:
R switch the engine off, open the driver's
door and remove your seat belt.
R open the hood.
The sounding of the horn alerts you to the fact that the vehicle has been parked while the HOLD function is still activated. If you attempt
to lock the vehicle, the tone becomes louder.
The vehicle is not locked until the HOLD func- tion is deactivated.
i If the engine has been switched off, it
cannot be started again until the HOLD
function has been deactivated.
If there is a malfunction in the system or
power supply while the HOLD function is acti- vated, the Brake Immediately
Brake Immediately message is
shown in the multifunction display. Immedi-
ately depress the brake firmly until the warn-
ing message in the multifunction display goes
out.
You can also shift the transmission to position
P. This deactivates the HOLD function. 4MATIC (permanent four-wheel drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
and
ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to insuffi-
cient grip.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic con- ditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in your lane.
If a drive wheel spins due to insufficient grip:
R Only depress the accelerator pedal as far as
necessary when pulling away.
R Accelerate less when driving.
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground or be fully raised. Observe the instructions for
towing the vehicle with all wheels in full
contact with the ground. Driving systems
185Driving and parking Z
i
In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer. When doing this, turn the SmartKey to posi-
tion 0or 1in the ignition. Failure to do this
can cause damage to the drive train or the brake system.
! A function or performance test should
only be carried out on a two-axle dyna-
mometer. Before you operate the vehicle
on such a dynamometer, please consult a
qualified workshop. You could otherwise
damage the drive train or the brake system. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and four sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park-
ing space. When maneuvering, parking or
pulling out of a parking space, make sure that there are no persons, animals or objects in
the area in which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars. PARK-
TRONIC does not detect such objects when
they are in the immediate vicinity of the
vehicle. You could damage the vehicle or
the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves. Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on uneven terrain.
PARKTRONIC is activated automatically when you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds. 0043
Sensors in the front bumper, left-hand
side (example)
Range of the sensors General notes
PARKTRONIC does not take objects into con-
sideration that are:
R below the detection range, e.g. people, ani-
mals or objects
R above the detection range, e.g. overhang-
ing loads, truck overhangs or loading ramps
The sensors must be free from dirt, ice or
slush. They can otherwise not function cor-
rectly. Clean the sensors regularly, taking
care not to scratch or damage them

When a parking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv-
er's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of Active Parking Assist by pressing the 0076

Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the curb. If necessary, you should can- cel the parking procedure with Active Park-
ing Assist.
R You can also select preselect transmission
position D. The vehicle redirects and does
not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A sen-
sible parking position can no longer be ach- ieved from this position.
Exiting a parking space In order that Active Parking Assist can sup-
port you when you exit the parking space:
R the border of the parking space must be
high enough at the front and the rear. A
curb is too small, for example.
R the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvering into the park-
ing space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
X Start the engine.
X Release the parking brake.
X Switch on the turn signal on the side facing

General notes The Active Driving Assistance package con-
sists of DISTRONIC PLUS (Y page 176), Active
Blind Spot Assist (Y page 207) and Active
Lane Keeping Assist (Y page 210).
Active Blind Spot Assist General notes
Active Blind Spot Assist uses a radar sensor
system to monitor the side areas of your vehi-
cle which are behind the driver. A warning
display in the exterior mirrors draws your
attention to vehicles detected in the moni-
tored area. If you then switch on the corre-
sponding turn signal to change lane, you will
also receive an optical and audible warning. If
a risk of lateral collision is detected, correc-
tive braking may help you avoid a collision. To support the course-correcting brake applica-
tion, Active Blind Spot Assist uses the
forward-facing radar sensor system. The free space is then evaluated in the direction of
travel and to the side before a course-cor-
recting brake application is initiated.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h). For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be operational.
Important safety notes
Active Blind Spot Assist is only an aid. It does
not detect all traffic situations and road users
and is no substitute for attentive driving.
Always ensure that there is sufficient dis-
tance to the side for other road users and
obstacles. G
WARNING
Active Blind Spot Assist does not react to:
R vehicles overtaken too closely on the side,
placing them in the blind spot area
R vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.

(30 km/h). At speeds above 20 mph
(30 km/h), the indicator lamp goes out and
Active Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp 0043on the corre-
sponding side lights up red. This warning is
always emitted when a vehicle enters the
blind spot monitoring range from behind or
from the side. When you overtake a vehicle,
the warning only occurs if the difference in
speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if reverse gear is engaged. In this event, Active Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light.
Visual and acoustic collision warning
When you switch on the turn signals to
change lanes and a vehicle is detected in the
side monitoring range, you receive a visual
and acoustic collision warning. You then hear a double warning tone and red warning
lamp 0043flashes. If the turn signal remains on,
detected vehicles are indicated by the flash-
ing of red warning lamp 0043. There are no fur-
ther warning tones.
Course-correcting brake application G
WARNING
A course-correcting brake application cannot always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the sides.
In very rare cases, the system may make an
inappropriate brake application. An inappro-
priate brake application may be interrupted at any time if you steer slightly in the opposite
direction or accelerate. If Active Blind Spot Assist detects a risk of a
lateral collision in the monitoring range, a
course-correcting brake application is carried
out. This is meant to assist you in avoiding a
collision.
The course-correcting brake application is
available in the speed range between 20 mph (30 km/h) and 120 mph (200 km/h).
If a course-correcting brake application
occurs, red warning lamp 0043flashes in the
exterior mirror and the following is shown in
the multifunction display, for example: Either a very slight course-correcting brake
application, or none at all, may occur if:
R there are vehicles or obstacles, e.g. crash
barriers, located on both sides of your vehi-
cle.
R a vehicle approaches you too closely at the
side.
R you have adopted a sporty driving style with
high cornering speeds.
R you clearly brake or accelerate.
R a driving safety system intervenes, e.g.
