Distronic displays in the speedometer
When the Distronic is activated, set
speed ; and distance warning lamp :
appear in the speedometer.
The vehicle speed displayed on the
speedometer can briefly vary from the speed
setting on the Distronic system.
When the Distronic detects a vehicle directly
ahead, the Distronic indicator lamp Ò in
the speedometer dial comes on white.
If the Distronic calculates that there is a
danger of collision, the distance warning lamp
Ò in the speedometer comes on red and
an intermittent warning sounds.
XImmediately apply the brakes to avoid a
collision.
Under no circumstances should the driver
await the intermittent warning sound
before braking.
The intermittent warning sound ceases and
the red distance warning lamp Ò goes
out when the necessary distance to the
vehicle ahead is established again.
GWarning!
An intermittent warning sounds and the
distance warning lamp (red) Ò in the
speedometer dial is illuminated if the
Distronic system calculates that the distance
to the vehicle ahead and your vehicle’s
current speed indicate that the Distronic will
not be capable of slowing the vehicle
sufficiently to maintain the preset following
distance, which creates a danger of a
collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your own
braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact being
avoided.
Tailgating increases the risk of an accident.
GWarning!
The Distronic brakes your vehicle with a
maximum deceleration of 6.5 ft/s2 (2 m/s2).
This corresponds to approximately 20% of the
maximum deceleration of your vehicle.
The Distronic brakes the vehicle in an effort
to restore the preset distance or to maintain
the set speed.
Distronic menu in the control system
The information shown in the multifunction
display depends on whether the Distronic
system and/or the distance warning function
are activated or deactivated.
iTo activate or deactivate the Distronic
system, see (Y page 136) or see
(Y page 138).

iIf you do not take your foot off of the
accelerator pedal and continue to
accelerate past the set speed, the following
message will appear in the multifunction
display:
DTR Override
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 pedal position.
Changing the set speedGWarning!
Keep in mind that it may take a brief moment
until the vehicle has made the necessary
adjustments.
Increase or decrease the set vehicle speed to
a value that the prevailing road conditions and
legal speed limits permit. Otherwise, sudden
and unexpected acceleration or deceleration
of the vehicle could cause an accident and/
or serious injury to you and others.
You can increase the set speed in 5 mph
(Canada: 10 km/h) increments or with fine
adjustment in 1 mph (Canada: 1 km/h)
increments. Decreasing the set speed is
possible in 5 mph (Canada: 10 km/h)
increments.
When you use the cruise control lever to
decelerate, the brake system will brake the
vehicle automatically if the engine’s braking
power does not brake the vehicle sufficiently.

Observe additional messages in the
multifunction display that may appear.
GWarning!
Distronic switches off and releases the brakes
when the vehicle decelerates below the
minimum speed of 20 mph (30 km/h) by
operation of the system. At that time the
driver must apply the brakes in order to
reduce vehicle speed further or bring it to a
stop.
Depressing the accelerator pedal does not
deactivate the Distronic. After a brief
acceleration (e.g. for passing), the Distronic
will resume the last set speed.
Setting the following distance in
Distronic
You can set the specified following distance
for Distronic by varying the time setting
between 1.0 and 2.0 seconds. Using this time
setting and the current speed of your vehicle,
Distronic calculates and sets the required
following distance to the preceding vehicle.
The set distance will be shown in the right
multifunction display.
GWarning!
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving
recommendations for safe following distance.

The thumbwheel for adjusting the following
distance is located on the right side of the
center console.
XIncreasing distance: Turn
thumbwheel : towards ª.
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the preceding vehicle.
XDecreasing distance: Turn
thumbwheel : towards ¥.
Decreasing the distance setting tells
Distronic to maintain a shorter following
distance to the preceding vehicle.
Driving with Distronic
This section describes a number of driving
situations where special precaution is
required on the part of the driver. Be prepared
to brake in such situations. Braking will
deactivate the Distronic system.
GWarning!
The Distronic works to maintain the speed
selected by the driver unless a moving
obstacle proceeding directly ahead of it in the
same travel direction is detected (e.g.
following another vehicle ahead of you at your
set distance).
This means that:
RYour vehicle can pass another vehicle after
you have changed lanes.
RWhile in a sharp turn or if the preceding
vehicle is in a sharp turn, the Distronic
could lose sight of the preceding vehicle.
Your vehicle could then accelerate to the
previously selected speed.
The Distronic regulates only the distance
between your vehicle and those directly
ahead of it, but does not register stationary
objects in the road, e.g.:
Ra stopped vehicle in a traffic jam
Ra disabled vehicle
Ran oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means of
steering or braking the vehicle.
GWarning!
The Distronic should not be used in snowy or
icy road conditions.
The most likely cause for a malfunctioning
system is a dirty Distronic system sensor
cover (located in the hood grille), especially
at times of snow and ice or heavy rain.
In such a case, the Distronic will switch off,
and the message DISTRONIC Currently
Unavailable – See Oper. Manual
appears in the multifunction display.
For cleaning and care of the Distronic system
sensor cover, see (Y page 218).
iIf the message DISTRONIC Currently
Unavailable – See Oper. Manual
disappears during driving, the dirt (e.g.
slush) has dissolved; the Distronic is
available again if you reactivate it

Hill-start assist system (SL 63 AMG)
On uphill grades, the hill-start assist system
maintains the pressure in the brake system
for approximately 1 second after you have
released the brake pedal. Therefore, you can

function as a parking brake. It does not
prevent the vehicle from moving when parked
on an incline.
