Important safety notes G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If you fail to adapt your driving style,
SPEEDTRONIC can neither reduce the risk of
accident nor override the laws of physics. SPEEDTRONIC cannot take account of road,
weather and traffic conditions.
SPEEDTRONIC 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
SPEEDTRONIC when the current road,
weather and traffic conditions permit it to be
done safely. Drive carefully and maintain a
suitable distance to the vehicle in front.
General notes
SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range
1,2or 3in 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
you need additional braking, depress the
brake pedal repeatedly rather than
continuously.

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 116) 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
1,2or 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.

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.

! 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 0or 1in 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
4MATIC 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. 124
