After approximately five seconds, current
saved speed ; is displayed in the status
indicator in the multifunction display:
R USA only: DTR XXX Miles
R Canada only: DTR XXX km/h
Deactivating DISTRONIC
There are a number of ways to deactivate
DISTRONIC:
XBriefly press the cruise control lever
forwards :.
or
XBrake.
i
The last speed stored remains stored until
you switch off the engine.
i DISTRONIC is not deactivated if you
depress the accelerator pedal. If you
accelerate to overtake, DISTRONIC adjusts
the vehicle's speed to the last speed stored
after you have finished overtaking.
DISTRONIC is automatically deactivated if:
R you apply the parking brake.
R you are driving slower than 20 mph
(25 km/h) and there is no vehicle in front,
or if the vehicle in front is no longer
detected.
R ESP ®
intervenes or if you deactivate ESP ®
.
R you shift the transmission to P, R or N.
If DISTRONIC is deactivated, you will hear a
warning tone. You will see the DISTRONIC
Off message in the multifunction display for
approximately five seconds.
Tips for driving with DISTRONIC
The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. DISTRONIC is then
deactivated.
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:
R Your vehicle can pass another vehicle after
you have changed lanes.
R While 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.:
R a stopped vehicle in a traffic jam
R a disabled vehicle
R an 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.

Crossing vehicles
DISTRONIC may detect vehicles that are
crossing your lane by mistake. Activating
DISTRONIC at, for example, a traffic light with
crossing traffic, could cause your vehicle to
pull away at the wrong time.
Level control
Important safety guidelines
Level control automatically adapts the vehicle
level to the current operating and driving
situation. This results in reduced fuel
consumption and improved handling.
Vehicles with ADS: when you are driving in
ADS COMF or ADS AUTO(Y page 194), the
vehicle is automatically lowered to high-
speed level as the speed increases. As the
vehicle speed decreases, the vehicle is raised
back up to highway level. In ADS
SPORT(Y page 194), the vehicle skips
highway level and is lowered directly to high-
speed level.
Make changes to the vehicle level while the
vehicle is in motion. This enables the vehicle
to adjust to the new level as quickly as
possible.
The vehicle level may change visibly if you
park the vehicle and the outside temperature
changes. If the temperature drops, the
vehicle level is lower; with an increase in
temperature, the vehicle level rises.
When you unlock the vehicle or open a door,
the vehicle begins to balance the load
discrepancies while still parked. However, for
significant level changes, e.g. after the
vehicle has been stationary for a long period,
the engine must be on. For safety reasons,
the vehicle is only lowered when the doors are
closed. Lowering is interrupted if a door is
opened, and it continues once the door has
been closed.
GWarning!
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when changing
the vehicle level. You could otherwise trap
yourself or others.
GWarning!
Always select as low a vehicle level as
possible. If the vehicle level is high, the vehicle
center of gravity shifts upwards. This
increases the risk of the vehicle tipping over.
Adapt your driving style to suit the vehicle
level. ESP® cannot reduce the risk of an
accident if you drive too fast. ESP® cannot
override the laws of physics.
! When driving on extremely rough terrain,
select a high vehicle level in good time.
Make sure that there is always sufficient
ground clearance to prevent damage to the
vehicle.
! Remove the key from the ignition before
raising one or more wheels with the
appropriate equipment.
Information on "Off-road driving"; see
(Y page 173).

the vehicle is lowered to high-speed level at
speeds higher than this.

R Off-road level 2 for driving on normal off-
road terrain
R Off-road level 1 for driving on easily

R –0.6 in (–15 mm) in high-speed level
Off-road levelsGWarning!
Vehicle off-road level 3 is not intended for use
on paved roads. This vehicle level is intended
for clearing impracticable situations at low
speed exclusively. The vehicle has a very high
center of gravity in off-road level 3. This
increases the overturning hazard.
R Select off-road level 3 exclusively for
clearing impracticable situations at low
speed.
R Adapt your driving style to the modified
conditions.
R Do not exceed a speed of 12 mph
(20 km/h).
R Avoid extreme, quick steering movements.
R Keep in mind the vehicle’s driving
characteristics are modified.
You should therefore drive in off-road level 3
with particular caution as it could otherwise
lead to an accident and/or serious injury to
you or others.
If you are driving too fast in off-road level 3,
the Reduce speed to under 12 mph
( 20 Km/h ) message appears in the
multifunction display. You also hear a
warning. The vehicle is lowered.
i You cannot clear these messages.
Only select an off-road level when this is
appropriate for road conditions. Otherwise,
fuel consumption increases and handling may
be affected.

ADS (Adaptive Damping System)
General notes
ADS is continuously electronically controlled.
It adapts the damping characteristics to the
current operating and driving situation.
Damping is controlled separately for each
wheel. This increases driving safety and tire
comfort.
This depends on:
R your driving style
R the road surface conditions
R the ADS setting
R the vehicle level setting
Your selection remains stored even if you
remove the key from the ignition lock.

PARKTRONIC
Important safety notes
GWarning!
The PARKTRONIC is a supplemental system.
It is not intended to, nor does it replace, the
need for extreme care. The responsibility
during parking and other critical maneuvers
always remains with the driver.GWarning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition.
R shift the transmission to position D, R or
N .
R release the parking brake.
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.
:Sensors in the front bumper, left-hand
side (example)
Range of the sensors
The sensors must be free of dirt, ice and
slush; otherwise they may not function
correctly. Clean the sensors regularly, taking
care not to scratch or damage them
( Y page 303).

! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
Ultrasonic sources such as an automatic
car wash, a truck's compressed-air brakes
or a pneumatic drill could cause
PARKTRONIC to malfunction.

If there is an obstacle within this range, all
warning displays light up and a warning tone
sounds. If the distance falls below the
minimum, the distance may no longer be
shown.
Warning displays
The warning displays show the distance
between the sensors and the obstacle. The
warning display for the front area is located
on the dashboard above the center air vents.
The warning display for the rear area is in the
roof lamp in the rear compartment.

The warning display for each side of the
vehicle is divided into five yellow and two red
segments. PARKTRONIC is operational if
yellow segments showing operational
