Cruise control is not deactivated if you
depress the accelerator pedal. For exam-
ple, if you accelerate briefly to overtake,
cruise control adjusts the vehicle's speed
to the last speed stored after you have fin-
ished overtaking.
i Deceleration of the vehicle by means of
the cruise control lever is assisted by auto-
matic application of the brakes.
Vehicles with automatic transmission*:
On long downhill gradients, the automatic
transmission shifts down as a further meas-
ure.

X Briefly press the cruise control lever in the
direction of arrow 5.
Variable Speedtronic is selected. LIM indi-
cator lamp 2in the cruise control lever
lights up.
Cruise control is automatically deactivated if,
for example:
R you depress the parking brake
R you are driving at less than 30 km/h
R ESP ®
is intervening or you deactivate
ESP ®
R you move the selector lever to Nin vehicles
with automatic transmission* while driving
If cruise control is deactivated, you will hear
a warning tone. You will see the Cruise con-
trol off message in the multi-function dis-
play for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. Distronic*
Distronic regulates the speed and automati-
cally maintains the distance to the vehicle in
front. It brakes automatically in order to avoid
exceeding 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 3. 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. 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 remains fully responsible
for the vehicle's distance from other vehi-
cles, the vehicle's speed and braking in
good time. Controls

Driving sys
tems 146 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
driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions
even when Distronic is activated. Other-
wise, you may fail to recognise dangers in
time, could 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 a preset distance to the vehicle in
front. G
Risk of accident
Distronic cannot take account of road and
traffic conditions. Deactivate, or do not
activate, 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 on filter lanes R
when changing to a lane with faster mov-
ing traffic
R in complex driving situations or where
the lanes are diverted, e.g. at motorway/
roadway 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
under braking or acceleration. The vehi-
cle could start to skid.
R if the sensors are dirty or there is poor
visibility, e.g. due to snow, rain or fog.
Distance control may be impaired.
Always pay attention to traffic conditions
even when Distronic is activated. Other-
wise, you may fail to recognise dangers in
time, could cause an accident and injure
yourself and others.
If there is no vehicle in front, Distronic oper-
ates in the same way as cruise control. Dis-
tronic functions in the 30 km/h to
180 km/h range. G
Risk of accident
Distronic brakes your vehicle at a maximum
of 2 m/s 2
, depending on its speed. This
corresponds to approximately 20% of your
vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If Distronic detects a risk of collision with a
vehicle in front, an intermittent warning
tone sounds. In addition, the ldistance
warning lamp in the instrument cluster
lights up. Brake to avoid a collision.

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.
Distance warning function Even if Distronic is deactivated, this function
warns you at speeds above 30 km/h if:
R
the distance to the vehicle in front is too
short for the speed you are driving at for
several seconds. The ldistance warn-
ing lamp in the instrument cluster then
lights up.
R you are approaching a vehicle in front at too
great a speed. You then hear an intermit-
tent warning tone, and the ldistance
warning lamp in the instrument cluster
lights up.
You must apply the brakes yourself in order
to maintain the correct distance to the vehicle
and to avoid a collision. G
Risk of accident
Be especially observant of traffic condi-
tions when the ldistance warning lamp
in the instrument cluster lights up or an
intermittent warning tone sounds. Brake or take evasive action as necessary.
i Distronic does not always clearly recog-
nise complex road and traffic conditions.
You may then receive a false distance warn-
ing tone or none at all.
X To activate/deactivate: press button1.
When the function is activated, indicator
lamp 2in the button lights up and a loud-
speaker symbol appears in the display.
When the function is deactivated, indicator
lamp 2in the button goes out and the
loudspeaker symbol disappears from the
multi-function display.

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 deacti-
vated. Cornering, going into and coming out of a
bend The ability of Distronic to detect vehicles
when cornering is limited. Your vehicle may
brake unexpectedly or belatedly.
Vehicles travelling on a different line Distronic may not detect vehicles travelling
on a different line. The distance to the vehicle
in front will be too short.
Other vehicles changing lane
Distronic has not yet detected the vehicle
cutting in. The distance to this vehicle will be

Narrow vehicles
Distronic has not yet detected the vehicle in
front on the edge of the carriageway, because
of its relatively narrow width. The distance to
the vehicle in front will be too short. 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
shift to a lower gear in good time or select
shift range 1,2or 3in vehicles with automatic
transmission*. 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. G
Risk of accident
Never depress the brake pedal continu-
ously 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 154) 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
Speedtronic.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
R LIM indicator lamp off:
cruise control or Distronic* is selected

the speed to any speed above 30 km/ hwhile
the engine is running. Controls

R when manoeuvring on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is cancelled and HOLD
deactivated when you depress the accelera-
tor pedal to pull away.
Activation conditions You can activate HOLD if:
R
the vehicle is stationary
R the engine is running
R the driver's door is closed
R the parking brake is not applied R
the bonnet is closed
R on vehicles with automatic transmission*,
the selector lever is in position D,Ror N
Activating HOLD X
Make sure that the activation conditions
are met.
X Depress the brake.
X Depress the brake again quickly until
HOLD appears in the display.
HOLD is activated. You can release the
brake pedal.
i If depressing the brake pedal the first
time does not activate HOLD, wait briefly
and then try again. G
Risk of accident
The vehicle's brakes are applied when
HOLD is activated. For this reason, deacti-
vate HOLD if the vehicle is to be set in
motion by other means (e.g. in a car wash
or by towing). Deactivating HOLD HOLD is deactivated if:
R
you accelerate. On vehicles with automatic
transmission*, only if the selector lever is
in position Dor R.
R the selector lever is moved to Pon vehicles
with automatic transmission*
R you release the brakes completely and
apply them again with a certain amount of
pressure until the HOLDmessage in the
multi-function display goes out G
Risk of accident
Never get out of the vehicle when HOLD is
activated.
HOLD must never be operated or deactiva-
ted by a passenger or from outside the
vehicle.
HOLD does not replace the parking brake
and must not be used for parking.

Multi-function display
A message appears in the multi-function dis-
play for approximately five seconds once you
have selected a damping program, for exam-
ple: 4MATIC* (permanent four-wheel
drive)
4MATIC ensures that all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip. G
Risk of accident
4MATIC cannot reduce the risk of an acci-
dent if you drive too fast.
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.
R Adapt your driving style to suit road and
traffic conditions.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tyres (M+S tyres), with snow
chains if necessary. Parktronic*
G
Risk of accident
Parktronic is only an aid and may not detect
all obstacles. It is not a substitute for atten-
tive driving.
You are always responsible for safety and
must continue to pay attention to your
immediate surroundings when parking and
manoeuvring. You could otherwise endan-
ger 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. It indi-
cates visually and audibly the distance
between your vehicle and an object.
Parktronic is automatically activated when
you switch on the ignition and release the
parking brake.
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. Controls
