Risk of accident
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintain a constant speed (e.g.
heavy traffic or winding roads). You could
otherwise cause an accident.
R on slippery roads. Braking or accelerating
could cause the drive wheels to lose trac-
tion and the vehicle could then skid.
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
Cruise control lever You can operate cruise control and variable
Speedtronic with the cruise control lever.

You could otherwise cause an accident and
injure yourself and others.
Storing and maintaining the current
speed You can store the current speed if you are
driving faster than 30 km/h and ESP ®
is acti-
vated (Y page 51).
X Accelerate the vehicle to the desired
speed.
X Briefly press the cruise control lever
up : or down ?to the pressure point.
X Remove your foot from the accelerator
pedal.
Cruise control is activated. The vehicle
automatically maintains the stored speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes. 118

will make use of the braking effect of the
engine, which relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly. G
Risk of accident
The brake pedal is retracted when Distronic
brakes. Do not restrict the movement of the
pedal in any way.
R Do not put any objects in the footwell.
R Ensure that floor mats and carpets are fixed
securely.
R Do not place your foot under the brake
pedal as it could become trapped.
You could otherwise cause an accident and
injure yourself and others. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Distronic is only an aid designed to assist
driving. The driver is fully responsible for the
vehicle's distance from other vehicles, the
vehicle's speed and for braking in good time.
Distronic does not react to:
R pedestrians
R stationary obstacles on the road, e.g. sta-
tionary or parked vehicles
R oncoming and crossing traffic
Distronic may not detect narrow vehicles driv-
ing in front, e.g. motorcycles, or vehicles driv-
ing on a different line. Therefore, always pay
attention to traffic conditions even when Dis-
tronic is activated. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourself and others.
If a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and maintain the preset distance to the vehicle in
front that you have set. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not acti-
vate, Distronic if it does not detect the vehicle
in front, or if it no longer detects it. This is
especially the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at motorway/road-
way construction sites
Otherwise, Distronic maintains the current
speed or accelerates to the set speed.
Distronic cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
If no car is driving in front of you, Distronic
works like cruise control in the speed range
between 30 km/h and 200 km/h. If a vehicle
is driving in front of you, Distronic Plus works
in the speed range between 0 km/h and
200 km/h.
Do not use Distronic while driving on roads
with steep gradients. 120

you ?or press it up :or down Ato the
pressure point.
Distronic is activated.
X Keep the cruise control lever pressed
up : or down Auntil 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 stored
speed.
i You can use the cruise control lever to set
the stored speed and the thumbwheel on
the cruise control lever to set the specified
minimum distance (Y page 123).
i If you do not fully release the accelerator
pedal, the DISTRONIC Override message
appears in the multi-function display. The
distance to a slower-moving vehicle in front
will then not be governed. You will be driv-
ing at the speed you determine by the posi-
tion of the accelerator pedal.
Driving
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control.
If a slower-moving vehicle is detected in front,
Distronic causes your vehicle to brake and
maintain the preset distance to the vehicle in
front.
If Distronic detects a faster-moving vehicle in
front, it increases the driving speed, but only
as far as the stored speed. G
Risk of accident
If you depress the brake pedal, Distronic is
deactivated. Distronic will then no longer
brake your vehicle. The driver is fully respon-
sible for the vehicle's distance from other
vehicles, its speed and for braking in good
time. Stopping G
Risk of accident
The Distronic braking effect is cancelled and
the vehicle can start moving if:
R Distronic is deactivated using the cruise
control lever.
R you accelerate.
R the system or the power supply is disrup-
ted, e.g. due to battery failure.
R the electrical system in the engine com-
partment or the fuses have been tampered
with.
R the battery is disconnected. G
Risk of accident
Distronic must never be operated or deacti-
vated by a passenger or from outside the vehi-
cle.
If you wish to leave the vehicle or park it,
deactivate Distronic and secure the vehicle
against rolling away.
If Distronic detects that the vehicle in front is
stopping, it brakes your vehicle until it is sta-
tionary.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill
about four metres behind the vehicle in
front. The specified minimum distance is
set using the thumbwheel on the cruise-
control lever.
Distronic is deactivated automatically when
stopping:
R on flat stretches of road or on downhill gra-
dients when the vehicle is stationary.
R while the vehicle is still moving on uphill
gradients, to prevent the vehicle from unex-
pectedly rolling back when Distronic is
deactivated.
If Distronic is deactivated, you will hear a
warning tone.
X Secure the vehicle against rolling away. 122

reduced.
Storing the current speed or call up the
last stored speed G
Risk of accident
Only select a stored speed if you know what
that speed is and whether it is suitable for the
current situation. Otherwise, sudden acceler-
ation or braking could endanger you or others.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator
pedal.
Distronic is activated and accepts the cur-
rent speed if it is activated for the first time,
or adjusts the vehicle's speed to the last
speed stored. Setting the specified minimum dis-
tance for Distronic You can set the specified minimum distance
for Distronic by varying the time span
between one and two seconds. This time span
determines the distance that Distronic should
maintain from the vehicle in front, depending
on the road speed. You can see this distance
in the multi-function display (Y
page 124). X
To increase: turn thumbwheel ;towards
=.
Distronic then maintains a greater distance
between your vehicle and the vehicle in
front.
X To decrease: turn thumbwheel ;
towards :.
Distronic then maintains a shorter distance
between your vehicle and the vehicle in
front.
i Make sure that you maintain the mini-
mum distance to the vehicle in front
required by law. Adjust the distance to the
vehicle in front if necessary. Driving systems

of its narrow width. The distance to the vehi-
cle in front will be too short.
Obstructions and stationary vehicles Distronic does not brake for obstructions or
stationary vehicles. If, for example, the detec-
ted vehicle turns a corner and there is an
obstacle or stationary vehicle ahead of it, Dis-
tronic will not brake for these.
Crossing vehicles Distronic may detect vehicles that are cross-
ing 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. Speedtronic
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 continu-
ously. G
Risk of accident
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You can set a variable or permanent limit
speed:
R variable for speed limits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. for driving on winter tyres
(Y page 128) G
Risk of accident
Speedtronic is only an aid designed to assist
driving. You are responsible for the vehicle's
speed and for braking in good time.
i The speed indicated in the speedometer
may differ slightly from the limit speed
stored.
Variable Speedtronic With the cruise control lever, you can operate
cruise control, Distronic* and variable Speed-
tronic.

ADS adapts the damping characteristics to
the current operating and driving situation.
How this is adjusted 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. You can choose between the following ADS
settings:
R
AUTO for normal driving situations; indica-
tor lamps ;and =are off.
R SPORT for sporty driving; indicator
lamp ;is on. In comparison to AUTOor
COMF, the vehicle is 15 mm lower.
R COMF for a more comfortable ride; indica-
tor lamp =is on.
X Start the engine.
X Press button :repeatedly until the
desired setting is selected. Level control
The level control adapts the vehicle level
automatically to the current operating and
driving situation. This results in reduced fuel
consumption and improved handling.
When you are driving in ADS COMForAUTO
ADS (Ypage 129), the vehicle is lowered to
the high-speed level as the speed increases.
As the vehicle decelerates, the vehicle is
raised back up to highway level.
In ADS SPORT (Ypage 129), 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 pos-
sible.
The vehicle level may change visibly when you
park the vehicle and the outside temperature
changes. When the temperature drops, the
vehicle level is lower; with an increase in tem-
perature, the vehicle level rises.
When you unlock the vehicle or open a door,
the vehicle begins to balance the load dis-
crepancies while still parked. However, for
significant level changes, e.g. after the vehi-
cle 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 continues when the door has
been closed. G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you begin
a level change. You could otherwise trap your-
self or others. G
Risk of accident
Always select as low a vehicle level as possi-
ble. If the vehicle level is high, the vehicle
centre of gravity shifts upwards. This increa-
ses the risk of the vehicle tipping over. Driving systems

G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles. It is not a substitute for
attentive driving.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
PARKTRONIC is an electronic parking aid
using ultrasound. 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 release the parking brake
R shift the automatic transmission to D,Ror
N
PARKTRONIC is deactivated at speeds above
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. :
Example: sensors in the front bumper,
