Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The use of the cruise control is recommended
for driving at a constant speed for extended
periods of time.
The currently set speed or last set speed
(“Resume” function) appears in the
multifunction display for approximately
5 seconds. The set speed is shown by a
triangle in the speedometer and the
corresponding speedometer segments from
the selected speed to the vehicle maximum
speed in the multifunction display are
illuminated. G
Warning!
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
Warning!
When the cruise control is braking, the brake
pedal is retracted (i.e. depressed
automatically). The pedals’ range of motion
must not be impeded by any obstacles:
R Do not place any objects in the footwell.
R Make sure that the floormats and carpets
are securely in place.
R Do not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others. :

Safety notes When activated, the DISTRONIC PLUS
adaptive
cruise
control system increases the
driving convenience afforded by the cruise
control while traveling on expressways and
other major roadways.
R If the DISTRONIC PLUS distance sensor
detects a slower moving vehicle directly
ahead, your vehicle speed will be reduced
so that you follow that vehicle at your
preset following distance.
R If there is no vehicle directly ahead of you,
the DISTRONIC PLUS will function in the
same way as standard cruise control
(Y page 302). G
Warning!
The DISTRONIC PLUS requires familiarity with
its operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system. 304

switched on. Otherwise, you may not be able
to recognize dangerous situations until it is
too
late.
This could cause an accident in which
you and/or others could be injured. G
Warning!
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
Warning!
Close attention to road and traffic conditions
is imperative at all times, regardless of
whether or not the DISTRONIC PLUS is
activated.
Use of the DISTRONIC PLUS can be
dangerous on
winding roads or in heavy traffic
because conditions do not allow safe driving
at a constant speed.
The DISTRONIC PLUS will not react to
stationary objects in the roadway (e.g. a
stopped vehicle in a traffic jam or a disabled
vehicle). The DISTRONIC PLUS will also not
respond to oncoming vehicles.
Switch off the DISTRONIC PLUS:
R when changing from the left to the right
lane if vehicles are moving more slowly in
the left lane
R when entering a turn lane or highway off
ramp
R in complex driving situations, such as in
highway construction zones
In these situations, the DISTRONIC PLUS will
continue to maintain the set speed unless
deactivated.
The DISTRONIC PLUS is designed and
intended only to maintain a set speed and
keep a set distance from moving objects in
front of it.
The DISTRONIC PLUS functions in a speed
range of 0 to 120 mph
(Canada: 0 to 200 km/h) if a preceding
vehicle is detected. If no preceding vehicle is
detected the DISTRONIC PLUS functions in a speed range of 20 to 120 mph
(Canada: 30 to 200 km/h).
Always obey applicable speed limits.
Do not use the DISTRONIC PLUS if you are
driving
on
a road with steep uphill or downhill
slopes.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 216). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada. When you switch off the radar sensor
system, the following functions are
deactivated:
R DISTRONIC PLUS
R BAS PLUS (Y page 57)
R PRE-SAFE ®
Brake (Y page 62)
R Park Assist ( Y page 324)

i Due to its radar-emitting nature
DISTRONIC PLUS may have an appearance
similar to a radar detector to law
enforcement officials. You may want to
refer to this section of your Operator’s
Manual when asked.

DISTRONIC PLUS displays in
multifunction display :
Speed of the vehicle ahead
; Marker

If the DISTRONIC PLUS is activated,
marker ; indicates the set speed.
The vehicle speed displayed on the
speedometer can briefly vary from the speed
setting on the DISTRONIC PLUS system.
If the DISTRONIC PLUS detects a vehicle
directly ahead, the ring on the speedometer
dial comes on between the speed of the
vehicle ahead : and the set speed. If the DISTRONIC PLUS calculates that there
is a danger of collision, the distance warning
lamp
· in the instrument cluster comes
on and an intermittent warning sounds.
X Immediately apply the brake to avoid a
collision.
Under no circumstances should the driver
await the intermittent warning sound
before braking. See the following warning
note.
The intermittent warning sound ceases and
the distance warning lamp · goes out
when the necessary distance to the vehicle
ahead is again established. G
Warning!
An intermittent warning sounds and the
distance warning lamp · in the instrument
cluster is illuminated if the DISTRONIC PLUS
system calculates that the distance to the
vehicle ahead and your vehicle’s current
speed indicate that the DISTRONIC PLUS will
not be capable of slowing the vehicle
sufficiently to maintain the preset following
distance, which creates a danger of a
collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your own
braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact being
avoided.
Tailgating increases the risk of an accident. G
Warning!
The DISTRONIC PLUS brakes your vehicle
with a maximum deceleration of 13 ft/s 2
(4 m/s 2
). This corresponds to approximately
40% of the maximum deceleration of your
vehicle. Driving systems

You must also apply the brakes yourself to
avoid a collision. The DISTRONIC PLUS brakes
the vehicle in an effort to restore the preset
distance or to maintain the set speed. The
brake pedal is automatically applied as this
happens which results in the brake pedal
moving
Keep driver’s foot area clear at all times,
including the area under the brake pedal.
Objects stored in this area may impair pedal
movement which could interfere with the
braking ability of the DISTRONIC PLUS
system.
Do not place your foot under the brake pedal
– your foot could become caught.
G
Warning!
If you do not receive visual or acoustic
warning signals during a critical traffic
situation, DISTRONIC PLUS has either not
recognized the collision risk, has been
deactivated or is malfunctioning.
Remember, whether or not DISTRONIC PLUS
is operating, it is ultimately always the drivers
responsibility to apply the brakes in order to
control the vehicle and avoid a collision.
