X
Accelerate the vehicle to the desired speed.
X Briefly press the cruise control lever up :or
down ?.
X Remove your foot from the accelerator pedal.
Cruise control is activated. The vehicle auto-
matically maintains the 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 auto-
matically braking the vehicle.
i Vehicles with manual transmission:
R Always drive at adequate, but not exces-
sive, engine speeds.
R Change gear in good time.
R If possible, do not change down several
gears at a time.
Storing the current speed or calling up the
last stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards
you =.
X Remove your foot from the accelerator pedal.
The first time cruise control is activated, it
stores the current speed or regulates the
speed of the vehicle to the previously stored
speed.
Setting a speed Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
X To adjust the set speed in10 km/hincre-
ments:
briefly press cruise control lever :up beyond the pressure point for a higher speed,
or down ?for a lower speed.
or X Keep the cruise control lever pressed beyond
the pressure point until the desired speed is
set. Press cruise control lever up :for a
higher speed or down ?for a lower speed.
X To adjust the set speed in1 km/hincre-
ments:
briefly press cruise control lever up :
to the pressure point for a higher speed or
down ?for a lower speed.
or X Keep the cruise control lever pressed to the
pressure point until the desired speed is set.
Press cruise control lever up :for a higher
speed or down ?for a lower speed.
i Cruise control is not deactivated if you
depress the accelerator pedal. For example, if
you accelerate briefly to overtake, cruise con-
trol adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control There are several ways to deactivate cruise con-
trol:
X Briefly press the cruise control lever forwards
B.
or X Brake.
or X Briefly press the cruise control lever in the
direction of arrow A.
The variable limiter is selected. LIM indicator lamp ;in the cruise control lever lights up.
Cruise control is automatically deactivated if:
R the vehicle is secured with the electric park-
ing brake
R you are driving at less than 30 km/h
R ESP ®
engages or you deactivate ESP ®
R while driving a vehicle with manual transmis-
sion, you shift into neutral or depress the
clutch pedal for longer than six seconds
R on vehicles with manual transmission, you
shift to a gear that is too high, and as a result
the engine speed is too low
R on vehicles with automatic transmission, you
shift to position Nwhile driving 164

If cruise control is deactivated, you will hear a
warning tone. You will see the Cruise con‐
Cruise con‐
trol off
trol off message in the multifunction display
for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. Speed limiter
General notes The limiter restricts the speed of the vehicle. The
limiter brakes automatically in order to adjust
the vehicle's speed to the stored speed.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. On vehi-
cles with automatic transmission, you need to
have selected the manual drive program
M (Y page 150). By doing so, you will make use
of the braking effect of the engine. This relieves
the load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
You can set a variable or permanent limit speed:
R Variable for maximum permissible speeds,
e.g. in built-up areas
R Permanent for a technically permitted max-
imum vehicle speed, e.g. when driving with
winter tyres fitted (Y page 166)
i The speed indicated in the speedometer
may differ slightly from the stored maximum
permissible speed.
Important safety notes If you fail to adapt your driving style, the speed
limiter can neither reduce the risk of an accident
nor override the laws of physics. The limiter can-
not take into account road, weather or traffic
conditions. The limiter 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.
If a new driver takes over, advise the new driver of the speed stored. Variable speed limiter General notes

B Switches off the speed limiter
With the cruise control lever, you can operate
cruise control or Distance Pilot DISTRONIC and
the variable speed limiter.
The LIM indicator lamp on the cruise control
lever indicates which system you have selected:
R LIM indicator lamp off: cruise control or Dis-
tance Pilot DISTRONIC is selected.
R LIM indicator lamp on: variable speed lim-
iter is selected.
When the engine is running, you can use the
cruise control lever to limit the speed to any
speed between 30 km/h and the maximum
design speed of the vehicle. If the set value of
the permanent limiter is lower then this value
applies (Y page 166).
Selecting the variable speed limiter
X Check whether LIM indicator lamp ;is on.
If it is on, the variable speed limiter is already
selected.
If it is not, press the cruise control lever in the direction of arrow A.

Distance Pilot DISTRONIC
General notes Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. The sys-
tem detects vehicles using the radar sensor sys-
tem. Distance Pilot DISTRONIC brakes automat- ically to avoid exceeding the set speed or to
maintain the designated distance from the vehi- cle in front.
If Distance Pilot DISTRONIC detects that there is
a risk of a collision, you will be warned visually
and acoustically. Without your intervention, Dis- tance Pilot DISTRONIC cannot prevent a colli-
sion. An intermittent warning tone will then
sound and the distance warning lamp will light
up in the instrument cluster. Brake immediately
to increase the distance to the vehicle in front,
or take evasive action, provided it is safe to do
so.
Distance Pilot DISTRONIC operates in the range between 0 km/h and 200 km/h.
Shift into a lower gear in good time on long andsteep downhill gradients. Take particular note of
this when driving a laden vehicle. By doing so,
you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Do not use Distance Pilot DISTRONIC on roads
with steep gradients.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Important safety notes G
WARNING
Distance Pilot DISTRONIC does not recognise
R people or animals
R stationary objects on the road, e.g. stopped
or parked vehicles
R oncoming vehicles or crossing traffic
As a result, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you. G
WARNING
Distance Pilot DISTRONIC brakes your vehicle with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you
with a visual and acoustic warning. There is a
risk of an accident.
Apply the brakes yourself in these situations
and try to take evasive action.
! When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations.
To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or similar situations:
R when towing away
R in a car wash
If you fail to adapt your driving style, Distance
Pilot DISTRONIC can neither reduce the risk of
an accident nor override the laws of physics.
Distance Pilot DISTRONIC cannot take into
account road, weather or traffic conditions. Dis-
tance Pilot DISTRONIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time

DISTRONIC General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend: the
ability of Distance Pilot DISTRONIC to detect
vehicles when cornering is limited. Your vehi-
cle may brake unexpectedly or late.
R Driving on a different line: Distance Pilot
DISTRONIC may not detect vehicles driving in
a different lane. The distance to the vehicle in
front will be too short.
R Other vehicles changing lane: Distance Pilot
DISTRONIC has not detected the vehicle cut-
ting in yet. The distance to this vehicle will be
too short.
R Narrow vehicles: Distance Pilot DISTRONIC
does not detect the vehicle in front on the
edge of the carriageway because of its narrow
width. The distance to the vehicle in front will
be too short.
R Obstacles and stationary vehicles: Distance
Pilot DISTRONIC does not brake for obstacles
or stationary vehicles. If, for example, the
detected vehicle turns a corner and an obsta-
cle or stationary vehicle is revealed, Distance Pilot DISTRONIC will not brake for them.
R Distance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. If
you activate Distance Pilot DISTRONIC under
the following conditions, the vehicle could
pull away unintentionally:
- at traffic lights with crossing traffic, for
example
- if there is a vehicle in front after a crossing
with the HOLD function activated
In such situations, brake if necessary. Distance Pilot DISTRONIC is then switched off. HOLD function
General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep slopes
R when manoeuvring on steep slopes
R when waiting in traffic 172

sound waves.
X Check to see if Parking Assist PARKTRONIC functions in a different
location. Parking Pilot
General notes Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting a parking space. Park- ing Assist PARKTRONIC is also available
(Y page 177).
i The active braking application is only avail-
able on vehicles with automatic transmission.
Important safety notes Parking Pilot is only an aid. It is not a substitute
for your attention to the immediate surround-
ings. The responsibility for safe manoeuvring
and parking remains with you. Make sure that no
persons, animals or objects are in the manoeu-
vring range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot parking procedure.
! If unavoidable, you should drive over obsta-
cles such as kerbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tyres.
Parking Pilot may also display spaces not suita- ble for parking, e.g.:
R in a zone where parking or stopping is pro-
hibited
R in front of driveways or entrances and exits
R on unsuitable surfaces 180
