DISTRONIC Plus*
When activated, the DISTRONIC Plus adap-
tive cruise control system increases the
driving convenience afforded by the cruise
control while traveling on expressways and
other major roadways.

If the DISTRONIC Plus distance sensor
detects a slower moving vehicle direct-
ly ahead, your vehicle speed will be re-
duced so that you follow that vehicle at
your preset following distance.

If there is no vehicle directly ahead of
you, DISTRONIC Plus will function in
the same way as standard cruise con-
trol (
page 405).
DISTRONIC Plus functions within a speed
range of 0 to 120 mph
(Canada: 0 to 200 km/h).When travelling in Canada in a vehicle not
registered in Canada, you must switch off
the radar sensor system* (
page 272).
Canadian law does not permit the use of
the radar sensor system* (
page 272) for
vehicles from outside of Canada. When you
switch off the radar sensor system*, the
following functions are deactivated:

BAS Plus* (page 67)

DISTRONIC Plus

Park Assist* (page 435)

PRE-SAFE® Brake* (page 73)
Warning!G
DISTRONIC Plus is a convenience system.
Its speed adjustment reduction capability is
intended to make the cruise control more ef-
fective and usable when traffic speeds vary.
It is not however, intended to, nor does it, re-
place the need for extreme care. The re-
sponsibility for the vehicle speed and the
distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
DISTRONIC Plus cannot take street and traf-
fic conditions into account.
Complex driving situations are not always
fully recognized by DISTRONIC Plus. This
could result in wrong or missing distance
warnings.

412 Controls in detail
Driving systems
Warning!G
DISTRONIC Plus adaptive cruise control is
no substitute for active driving involvement.
It does not react to pedestrians or stationary
objects, nor does it recognize or predict the
curvature and lane layout or the movement
of vehicles ahead. DISTRONIC Plus can only
apply a maximum of 40% of the vehicle’s
braking power.
DISTRONIC Plus may not detect narrow ve-
hicles possibly driving in front of you, such
as motorcycles and vehicles driving in an
offset formation.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic con-
ditions and to provide the steering, braking
and other driving inputs necessary to retain
control of the vehicle.
High-frequency sources such as toll sta-
tions, speed measuring systems etc. can
cause the DISTRONIC Plus system to tem-
porarily cease functioning.
Warning!G
DISTRONIC Plus requires familiarity with its
operational characteristics. We strongly rec-
ommend that you review the following infor-
mation carefully before operating the
system.
Warning!G
DISTRONIC Plus cannot take street and traf-
fic conditions into account. Only use
DISTRONIC Plus if the road, weather and
traffic conditions make it advisable to travel
at a steady speed.
Warning!G
Use of DISTRONIC Plus can be dangerous
on slippery roads. Rapid changes in tire trac-
tion can result in wheel spin and loss of con-
trol.
DISTRONIC Plus does not act upon adverse
sight distance conditions. Do not use
DISTRONIC Plus during conditions of fog
and heavy rain, snow or sleet.
Warning!G
DISTRONIC Plus cannot take weather condi-
tions into account. Switch off
DISTRONIC Plus or do not turn it on if:

roads are slippery or covered with snow
or ice. The wheels could lose traction
while braking or accelerating, and the
vehicle could skid.

the sensor is dirty or visibility is
diminished due to snow, rain or fog. The
distance control could be impaired.
Always pay attention to traffic conditions
even while DISTRONIC Plus is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident resulting in person-
al or fatal injury to you or others.

Switching on when approaching a
stationary vehicle
If the vehicle in front of you is stationary,
you can only switch on DISTRONIC Plus if
your vehicle is also at a standstill.
Tap DISTRONIC Plus lever up1 or
down2 until desired speed is set.
DISTRONIC Plus is switched on.
or
Pull DISTRONIC Plus lever briefly in di-
rection of arrow4 to call up speed
last set (
page 423).
DISTRONIC Plus is switched on.Starting off
When the vehicle in front of you starts off:
Remove your foot from the brake
pedal.
Pull DISTRONIC Plus lever briefly in di-
rection of arrow4.
or
Briefly step on the accelerator pedal.
Your vehicle starts off and adapts its speed
to the vehicle in front of you.Driving
If no vehicle is driving ahead of you,
DISTRONIC Plus functions like the cruise
control (
page 405).
When DISTRONIC Plus detects that the ve-
hicle in front of you is driving more slowly,
it brakes the vehicle in order to keep the
distance specified by you.
When DISTRONIC Plus detects that the ve-
hicle in front of you is driving faster, the ve-
hicle accelerates up to the set speed.
iIt is helpful to switch on the DISTRONIC Plus
display in the instrument cluster (
page 416)
since you can only switch on DISTRONIC Plus un-
d e r a s p e e d o f 2 0 m p h ( 3 0 k m / h ) w h e n a v e h i c l e
has been detected in front of you.
iYou can adjust the set speed using the
DISTRONIC Plus lever and the target distance
using the distance setting switch on the
DISTRONIC Plus lever (
page 425).
iIf DISTRONIC Plus is switched off,
PRE-SAFE® Brake* (page 73) will warn of an
impending collision if this function has been
activated with the instrument cluster control
system (
page 268).
Warning!G
When you step on the brake pedal, you
switch off DISTRONIC Plus except when the
vehicle is at a standstill. DISTRONIC Plus will
no longer brake your vehicle. You are always
responsible for maintaining a distance from
other vehicles, observing road speeds and
braking well in advance.

504 Operation
Driving instructions
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.
An electronic speed limiter prevents your
vehicle from exceeding a speed of
130 mph (210 km/h).The factory equipped tires on your vehicle
may have a tire speed rating above the
maximum speed permitted by the elec-
tronic speed limiter.
Make sure your tires have the required tire
speed rating as specified for your vehicle in
the “Technical data” section (
page 678),
for example when purchasing new tires.
For information on how to identify the tire
speed rating on a tire’s sidewall, see “Tire
size designation, load and speed rating”
(
page 536).
If you are uncertain about the correct read-
ing of the information given on a tire’s side-
wall, any authorized Mercedes-Benz
Center will be glad to assist you.
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
or DISTRONIC Plus* system under such
conditions.
When the vehicle is in danger of skidding,
move gear selector lever to position N. Try
to keep the vehicle under control by cor-
rective steering action.
Warning!G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or serious
personal injury and possible death, for you
and for others.
iFor information on speed ratings for winter
tires, see (
page 539) and (page 549).
iFor information on driving with snow chains,
see “Snow chains” (
page 550).
Warning!G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.
