XAccelerate the vehicle to the desired speed.
XBriefly press the cruise control lever up:or
down ;.
XRemove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the stored speed.
iCruise control may be unable to maintain
the stored speed on uphill and downhill gra-
dients. The stored speed is resumed when the
gradient levels out. Cruise control maintains
the stored speed on downhill gradients by
automatically applying the brakes.
Calling up the stored speed
GWARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you ?.
XRemove your foot from the accelerator pedal.
Cruise control is activated and adjusts the
vehicle's speed to the last speed stored.
If no speed is stored, cruise control stores the
current speed and maintains it.
Setting a speed
Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
XPress the cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly press
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 in 5 mph incre-
ments (10 km/h increments): briefly pressthe 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.
iCruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate to overtake, cruise control adjusts the
vehicle's speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:
XBriefly press the cruise control lever forwards
=.
or
XBrake.
Cruise control is automatically deactivated if:
Ryou apply the parking brake
Ryou are driving at less than 20 mph (30 km/h)
RESP®intervenes or you deactivate ESP®
Ryou shift the automatic transmission to posi-
tion iwhile driving
Ryou engage a differential lock
If cruise control is deactivated, a warning tone
sounds. You will see the Cruise Control Off
message in the multifunction display for approx-
imately five seconds. The message on the mul-
tifunction display disappears and the segments
on the speedometer go out.
iWhen you switch off the engine, the last
speed stored is cleared.
DISTRONIC PLUS
General notes
DISTRONIC PLUS regulates the speed and auto-
matically helps you maintain the distance from
the vehicle detected in front. Vehicles are detec-
ted with the aid of the radar sensor system.
DISTRONIC PLUS brakes automatically so that
the set speed is not exceeded.
Change into a lower gear in good time on long
and steep downhill gradients.
This is especially important if the vehicle is
laden. By doing so, you will make use of the
braking effect of the engine. This relieves the
134Driving systems
Driving an d parking

Do not use DISTRONIC PLUS:
Rin road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line.
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
covering the sensors
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-
ple, in parking garages
If DISTRONIC PLUS no longer detects a vehicle
in front, DISTRONIC PLUS may unexpectedly
accelerate the vehicle to the stored speed.
This speed may:
Rbe too high if you are driving in a filter lane or an exit lane
Rbe so high in the right lane that you pass vehi-cles driving on the left (left-hand drive coun-
tries)
Rbe so high in the left lane that you pass vehi-
cles driving on the right (right-hand drive
countries)
If there is a change of drivers, advise the new
driver of the speed stored.

Activation conditions
In order to activate DISTRONIC PLUS, the fol-
lowing conditions must be fulfilled:
Rthe engine must be started. It may take up to
two minutes after pulling away before
DISTRONIC PLUS is operational.
Rthe parking brake must be released.
Rthe differential lock must be disengaged.
RESP®must be active, but not intervening.
Rthe automatic transmission is in position h.
Rthe driver's door must be closed or your seat
belt must be fastened when you shift the

Rthe front-passenger door and rear doors must
be closed.
Rthe vehicle must not slide.
Rthe transfer case must in the HIGH RANGE
on-road position.
Rthe vehicle must not be on an uphill or down-
hill gradient of more than 22‑25%.
Activating
XBriefly pull the cruise control lever towards
you ?, up :or down ;.
DISTRONIC PLUS is activated.
XRemove your foot from the accelerator pedal.
The vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
If you do not fully release the accelerator
pedal, the DISTRONIC PLUS Passive
mes-
sage appears in the multifunction display. The set distance to a slower-moving vehicle in
front will then not be maintained. You will be
driving at the speed you determine by the
position of the accelerator pedal.

You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is
20 mph (30 km/h).
XBriefly pull the cruise control lever towards
you?, up :or down ;.

Activating at the current speed/last
stored speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an acci-
dent.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you
do not know the stored speed, store the
desired speed again.
XBriefly pull the cruise control lever towards
you ?.
XRemove your foot from the accelerator pedal.
DISTRONIC PLUS is activated. The first time it
is activated, the current speed is stored. Oth-
erwise, it sets the vehicle speed to the previ-
ously stored value.
Driving with DISTRONIC PLUS
Pulling away and driving
XIf you want to pull away with DISTRONIC
PLUS: remove your foot from the brake pedal.
XBriefly pull the cruise control lever towards
you?.
or
XAccelerate briefly.
The vehicle pulls away and adapts its speed to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to
the stored speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ- ent line from another vehicle. The vehicle then
brakes automatically.
If DISTRONIC PLUS does not detect a vehicle in
front, the system operates like a cruise control.
If DISTRONIC PLUS detects that the vehicle in
front is driving slower, your vehicle brakes. In this way, the specified minimum distance you
have selected is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed to
the set speed.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
Selecting the drive program
DISTRONIC PLUS supports a sporty driving style
when you have selected the
Sdriving program
(
Ypage 116). Acceleration behind the vehicle in
front or to the set speed is then noticeably more dynamic. If you have selected drive program Eor
C (Mercedes-AMG vehicles), the vehicle accel-
erates more gently. This setting is recommen-
ded in stop-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
Ryou are driving faster than 40 mph (60 km/h)
RDISTRONIC PLUS is maintaining the distance
to a vehicle in front
Ryou switch on the appropriate turn signal
RDISTRONIC PLUS does not detect a danger of
collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
When changing lanes, DISTRONIC PLUS moni-
tors the left lane on left-hand drive vehicles and
the right lane on right-hand drive vehicles.
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.
Driving systems137

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 139).
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is
stationary.
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.
The automatic transmission shifts automatically
to transmission position jif DISTRONIC PLUS
is activated and:
Rthe driver's seat belt is not fastened and the
driver's door is open.
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
On steep uphill or downhill inclines, or if there is
a malfunction, the automatic transmission may
also automatically be shifted to pos
ition

Setting a speed
XPush the cruise control lever upwards :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments):briefly push
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 in 5 mph incre-
ments (10 km/h increments): briefly push
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. If you accelerate to overtake, DISTRONIC PLUS
adjusts the vehicle's speed back to the last
speed stored after you have finished overtaking.
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 167).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.
Adjust the distance to the vehicle in front if nec-
essary.
XTo increase: turn control;in direction =.
DISTRONIC PLUS then maintains a greater
distance between your vehicle and the vehicle
in front.
XTo decrease: turn control;in direction :.
