WARNING
DISTRONIC PLUS is deactivated and releases
the brakes if the vehicle is slowed down to a
speed
below 20 mph (30km/h) by the system,
provided that DISTRONIC PLUS does not
detect a vehicle directly in front. At this point,
the driver must apply the brakes in order to
slow down further and bring the vehicle to a
standstill. There are several ways to deactivate
DISTRONIC PLUS:
X
Briefly press the cruise control lever
forwards :.
or
X Brake, unless the vehicle is stationary.

Tips for driving with DISTRONIC PLUS Important safety notes
G
WARNING
The DISTRONIC PLUS works to maintain the
speed
selected by the driver unless a moving
obstacle proceeding directly ahead of it in the
same travel direction is detected (e.g.
following another vehicle ahead of you at your
set distance).
This means that:
R Your vehicle can pass another vehicle after
you have changed lanes.
R While in a sharp turn or if the preceding
vehicle is in a sharp turn, the DISTRONIC
PLUS could lose sight of the preceding vehicle. Your vehicle could then accelerate
to the previously selected speed.
The DISTRONIC PLUS regulates only the
distance between your vehicle and those
directly ahead of it. It may not register
stationary objects in the road, e.g.:
R a stopped vehicle in a traffic jam
R a disabled vehicle
R an oncoming vehicle
The driver must always be alert, observe all
traffic
and intercede as required by means of
steering or braking the vehicle. G
WARNING
The DISTRONIC PLUS should not be used in
snowy or icy road conditions.
The
following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. DISTRONIC PLUS is then
deactivated.
Cornering, going into and coming out of a
bend The ability of DISTRONIC PLUS to detect
vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late. Driving systems

HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R
when pulling away, especially on steep
slopes
R when maneuvering on steep slopes
R when 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.
Activation conditions You can activate the HOLD function if:
R
the vehicle is stationary.
R the engine is running or if it has been
automatically switched off by the ECO
start/stop function.
R the
driver's door is closed or your seat belt
is fastened.
R the parking brake is released.
R the hood is closed.

Activating the HOLD function G
WARNING
The vehicle's brakes are applied when the
HOLD function is activated. For this reason,
deactivate
the HOLD function if the vehicle is
to be set in motion by other means (e.g. in a
car wash or by towing). X
Make sure that the activation conditions
are met.
X Depress the brake pedal.
X Quickly depress the brake pedal further
until ë appears in the multifunction
display.
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 G
WARNING
Never get out of the vehicle when the HOLD
function is activated.
The HOLD function must never be operated
or
deactivated by a passenger or from outside
the vehicle.
The HOLD function does not replace the
parking brake and must not be used for
parking.
The braking effect of the HOLD function is
canceled and the vehicle could roll away if:
R the HOLD function is deactivated by
depressing the accelerator pedal or the
brake pedal.
R there is a malfunction in the system or an
interruption in the power supply, e.g.
battery failure.
R the electrical system in the engine
compartment, the battery or the fuses are
tampered with.
R the battery is disconnected.
If you leave the vehicle or park it, deactivate
the HOLD function and secure the vehicle
against rolling away.
The HOLD function is deactivated

sports mode
General notes The most important part of the dynamic
handling package with sports mode is the
adjustable damping system. This
automatically controls and adapts the
suspension to the respective driving
situation.
The calibration of the suspension depends
on:
R
your driving style
R the road surface conditions
R your individual selection; see the following
description
The dynamic handling package with sports
mode also includes steering wheel paddle
shifters (Y page 160) with a manual drive
program ( Y page 162).
Sports tuning Example: position of dynamic handling package
with sports mode button
The
firmer setting of the suspension tuning in
sports mode ensures even better contact
with the road. Select this mode when
employing a sporty driving style, e.g. on
winding country roads.

Range of the sensors
General notes
!
When
parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC 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. :
Example: sensors in the front bumper,
left-hand side
The sensors must be free of dirt, ice and
slush. Otherwise, they may not function
correctly.
Clean the sensors regularly, taking
care not to scratch or damage them
(Y page 304). Example: side view

the rear seats.
The warning display for each side of the

Important safety notes G
WARNING
Parking Guidance is merely an aid and may
display parking spaces that are not suitable
for parking, for example:
R no-parking areas
R parking spaces with unsuitable surfaces
(road surface)
R driveways
R entrances and exits
Parking Guidance detects and measures
potential parking spaces while driving past.
Changes
to the parking space after this point
are not taken into account, for example if the
vehicle in front of or behind the parking space changes position or objects in the parking
space are moved.
Even when using Parking Guidance, you are
still responsible for driving carefully. If you
rely on Parking Guidance alone, you could
cause an accident and injure yourself and
others.
Safety
always remains your responsibility and
you must continue paying careful attention to
your immediate surroundings when parking
and maneuvering. G
WARNING
Objects located above the height range of
Parking Guidance will not be detected when
the
parking space is measured. These objects
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods 194
Driving systems
Driving and parking
When a parking space has been detected, an
arrow
towards the right = or the left : also
appears. Parking Guidance only displays
parking spaces on the front-passenger side
as standard. Parking spaces on the driver's
side are displayed as soon as the turn signal
on the driver's side is activated. To park on
the driver's side, you must leave the driver's
side turn signal switched on until you have
engaged reverse gear.
Parking Guidance will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 5 ft (1.5 m) wide
R that are at least 4.3 ft (1.3 m) longer than
your vehicle
A parking space is displayed while you are
driving past it, and until you are
approximately 50 ft (15 m) away from it.

G
WARNING
The Parking Guidance is only an aid and may
not detect all obstacles. The Parking
Guidance does not relieve you of the

to pay attention. You are always
responsible for safety and must continue to
pay attention to your immediate surroundings
when parking and maneuvering. Otherwise,
you could endanger yourself and others.
