road, weather and traffic conditions.
DISTRONIC PLUS is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane. Only engage
DISTRONIC PLUS when the current road,
weather
and traffic conditions permit it to be
done safely, and adapt your driving style
accordingly. Drive carefully and maintain a
suitable distance to the vehicle in front.
If DISTRONIC PLUS detects a risk of collision
but cannot sufficiently decelerate the vehicle
in order to maintain the set distance, you will
be warned visually and acoustically.
DISTRONIC PLUS cannot prevent a collision
without your intervention. An intermittent
warning tone will then sound and the distance
warning lamp will light up in the instrument
cluster. Brake immediately in order to
increase the distance from the vehicle in
front, or take evasive action, provided it is
safe to do so.
DISTRONIC PLUS may not detect narrow
vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line. Therefore,
always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognize dangers
in time, cause an accident and injure yourself
and others.
In particular, the detection of obstacles can
be impaired if there is:
R the sensor is dirty or covered
R snow or heavy rain
R interference by other radar sources
R there is the possibility of strong radar
reflections, for example, in parking
garages.
If DISTRONIC PLUS is activated, the vehicle
brakes automatically in certain situations.
This can happen unexpectedly, especially
when towing or in a car wash. There is a risk
of an accident. In these or similar situations,
deactivate DISTRONIC PLUS.
If you want DISTRONIC PLUS to assist you,
the following activation conditions must be fulfilled (
Y page 179) and the radar sensor
system must be operational.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
DISTRONIC PLUS brakes automatically so
that the set speed is not exceeded.
On long and steep downhill gradients,
especially if the vehicle is laden or towing a
trailer, you must select shift range
1, 2 or 3
in good time. By doing so, you will make use
of the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle
in front, your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and120 mph (Canada:
200 km/h). If a vehicle is driving in front of
you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

Activating while driving
When driving at speeds below 20 mph
(30
km/h) you can activate DISTRONIC PLUS
if the vehicle in front has been detected and
is shown in the multifunction display. If the
vehicle in front is no longer detected and
displayed, DISTRONIC PLUS switches off and
a tone sounds.
X Briefly pull the cruise control lever towards
you ?, or press it up : or down A.
DISTRONIC PLUS is selected.
X Press the cruise control lever up : or
down A
repeatedly until the desired speed
is set.
X Remove your foot from the accelerator
pedal.
Your
vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
i If
you do not fully release the accelerator
pedal, the DISTRONIC PLUS Passive
message 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. Switching on while stationary
This function may be useful if you want to
keep up with the traffic flow, e.g. at the end
of a tailback.
You can only activate DISTRONIC PLUS if:
R
the vehicle in front and
R your vehicle are stationary
X Briefly pull the cruise control lever towards
you ?, or press it up : or down A.
DISTRONIC PLUS is selected.
i DISTRONIC PLUS can be activated at a
standstill at under 20 mph (30 km/h
) only
if a vehicle in front has been detected.
Therefore, the DISTRONIC PLUS distance
display in the instrument cluster should be
activated (Y page 218).
X Keep the cruise control lever pressed
up : or down A until the desired speed
is set.
i You
can use the cruise control lever to set
the stored speed and the control on the
cruise control lever to set the specified
minimum distance (Y page 183).
Activating at the current speed/last
stored speed G
WARNING
If you call up the stored speed and it differs
from the current speed, the vehicle
accelerates
or decelerates. If you do not know
the stored speed, the vehicle could accelerate
or brake unexpectedly. There is a risk of an
accident.
Pay attention to the road and traffic
conditions before calling up the stored speed.
If you do not know the stored speed, store the
desired speed again.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator
pedal.
DISTRONIC PLUS is activated. The first
time it is activated, the current speed is180

stored. Otherwise, it sets the vehicle cruise
speed to the previously stored value.
Driving with DISTRONIC PLUS Pulling away and driving
X
If the vehicle in front pulls away: remove
your foot from the brake pedal.
X Briefly pull the cruise control lever towards
you ?, or press it up : or down A.
or
X Accelerate briefly.
Your vehicle pulls away and adapts its
speed to that of the vehicle in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle
in front has slowed down, it brakes your
vehicle. In this way, the distance you have
selected is maintained.
If DISTRONIC PLUS detects that the vehicle
in front is driving faster, it accelerates your
vehicle, but only up to the speed you have
stored.
If
you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary. Changing lanes
If
you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 40 mph
(60 km/h).
R DISTRONIC PLUS is maintaining the
distance to a vehicle in front.
R you switch on the appropriate turn signal.
R DISTRONIC 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.
i When changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.
Stopping G
WARNING
When leaving the vehicle, even if it is braked
only
by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a
vehicle occupant or from outside the
vehicle.
R the electrical system in the engine
compartment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.

! Never tow the vehicle with one axle
raised.
This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
! When testing the parking brake, operate
the vehicle only briefly (for a maximum of
ten seconds) on a brake test dynamometer.
When doing this, turn the SmartKey to
position 0 or 1 in the ignition. Failure to do
this can cause damage to the drive train or
the brake system.
! A function or performance test should
only be carried out on a two-axle
dynamometer. Before you operate the
vehicle on such a dynamometer, please
consult a qualified workshop. You could
otherwise damage the drive train or the
brake system.
4MATIC ensures that all four wheels are
permanently driven. Together with ESP ®
and
4ETS, it improves the traction of your vehicle
whenever a drive wheel spins due to
insufficient grip.
If a drive wheel spins due to insufficient grip:
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Accelerate less when driving.
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane. Only engage
