Activating DISTRONIC Plus
You can activate DISTRONIC Plus when:


you are driving slower than 20 mph
(30 km/h) and DISTRONIC Plus has
detected a vehicle ahead of you


you are driving above 20 mph
(30 km/h)
If DISTRONIC Plus has not been activated
after pressing the DISTRONIC Plus lever,
you will see the message: “DISTRONIC
PLUS - - - mph” (Canada: “DISTRONIC PLUS
- - - kmh”) in the multifunction display.
Warning!
G
When DISTRONIC Plus is braking, the brake
pedal is retracted (i.e. depressed automati-
cally). The pedals’ range of motion must not
be impeded by any obstacles:

Do not place any objects in the footwell.


Make sure that the floor mats and car-
pets are securely in place.


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 others.
Warning!
G
When DISTRONIC Plus is switched on, the
vehicle can be braked. You should therefore
switch off DISTRONIC Plus if the vehicle
must be towed.i
The maximum speed you can set is 120 mph
(Canada: 200 km/h).

450 Controls in detailDriving systemsIn the following cases you cannot activate
DISTRONIC Plus:

up to 2 minutes after starting the en-
gine


if the engine is switched off


if you step on the brake pedal while
driving


the vehicle is secured with the elec-
tronic parking brake


if the gear selector lever is in park
positionP, reverse gearR, or neutral
positionN


if ESP
® is switched off


if the hood is open


if the driver’s door is open and the driv-
er has not fastened his or her seat belt


if the radar sensors are switched off
(page 302).Switching on while driving

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 455).
DISTRONIC Plus is switched on.

Take your foot off the accelerator ped-
al.
Your vehicle adapts its speed to the ve-
hicle ahead, observing the set speed as
a maximum value.
i
Under 20 mph (30 km/h), you can only
switch on DISTRONIC Plus if the vehicle ahead of
you has been detected and is shown on the mul-
tifunction display. If you no longer see the vehi-
cle in front of you on the multifunction display
and if it is no longer detected because it has
changed lanes, for example, DISTRONIC Plus
switches off and you will hear a signal.
i
If you do not completely lift your foot off the
accelerator pedal, the message
“DISTRONIC PLUS Override” appears on the
multifunction display. The distance to a slow-
er-driving vehicle will not be set. You will drive at
the speed you dictate by pressing the accelera-
tor pedal.

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 455).
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 437).
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.
i
It is helpful to switch on the DISTRONIC Plus
display in the instrument cluster (
page 448)
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.
i
You 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 457).
i
If DISTRONIC Plus is switched off,
PRE-SAFE
® Brake* (
page 75) will warn of an
impending collision if this function has been
activated with the instrument cluster control
system (
page 298).
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.

452 Controls in detailDriving systemsStoppingWhen DISTRONIC Plus detects that the ve-
hicle in front of you is stopping, the vehicle
brakes until it also stops.
Once DISTRONIC Plus has stopped your
vehicle and it is at a standstill, it remains
stationary; the brake pedal does not need
to be depressed.Warning!
G
DISTRONIC Plus’s braking effect is canceled
and the vehicle can start to roll if

DISTRONIC Plus is switched off using
the DISTRONIC Plus lever


you accelerate


the system or the power supply is mal-
functioning, e.g. due to battery failure


the electrical components in the engine
compartment or the fuses have been
manipulated


the battery is disconnected
Warning!
G
Never get out of the vehicle while
DISTRONIC Plus is switched on!
DISTRONIC Plus must never be operated or
switched off by passengers or from outside
the vehicle.
DISTRONIC Plus is not a substitute for the
electronic parking brake and may not be
used for parking.
When you get out of the vehicle or switch off
the engine, deactivate DISTRONIC Plus and
secure the vehicle from rolling away by en-
gaging the electronic parking brake.
i
After a short while, your vehicle is secured in
place by the electronic parking brake so that the
operating brake can be relieved of load.
i
Depending on the following distance set us-
ing the distance setting switch on the DISTRON-
IC Plus lever, your vehicle will stop
approximately 13.1 ft away from the vehicle in
front of you.

Accelerate or decelerate to the desired
speed.

Briefly lift the DISTRONIC Plus lever in
the direction of arrow1 or depress in
the direction of arrow2.
DISTRONIC Plus is activated and the
current speed is set.

Remove your foot from the accelerator
pedal.Setting a higher speed
You can increase the set speed in two
ways.Adjustment in 1 mph (Canada: 1 km/h)
increments

Briefly lift the DISTRONIC Plus lever up
to the resistance point in direction of
arrow1 (
page 449).

Release the DISTRONIC Plus lever.
The vehicle speed increases in incre-
ments of 1 mph (Canada: 1 km/h).
i
If you do not take your foot off of the accel-
erator completely, the following message
“DISTRONIC PLUS Override” will appear in the
multifunction display.
The distance to a slower moving vehicle in front
of you will not be set. Your vehicle speed will
then be determined only by the accelerator ped-
al position.
Warning!
G
If you increase the set speed, keep in mind
that it may take a brief moment until the ve-
hicle has reached the set speed.
Increase the set speed to a value that the
prevailing road conditions and legal speed
limits permit. Otherwise, sudden and unex-
pected acceleration of the vehicle could
cause an accident and/or serious injury to
you and others.
i
The set speed value is increased in 1 mph
(Canada: 1 km/h) increments each time you lift
the DISTRONIC Plus lever up to the resistance
point.

The new speed is set and the vehicle will ac-
celerate. Keep in mind that it may take a brief
moment until the vehicle has reached the set
speed.
Warning!
G
If you decrease the set speed, keep in mind
that it may take a brief moment until the ve-
hicle has reached the set speed.
Decelerate the set speed to a value that the
prevailing road conditions and legal speed
limits permit. Otherwise, sudden and unex-
pected deceleration of the vehicle could
cause an accident and/or serious injury to
you and others.i
When you use the DISTRONIC Plus lever to
decelerate, the brake system will automatically
brake the vehicle if the engine’s braking power
does not brake the vehicle sufficiently.
