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

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).

Do not use Distance Pilot DISTRONIC:
R in road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic or on winding roads.
R on smooth or slippery roads. Braking or accel-
erating can cause the drive wheels to lose
traction and the vehicle could then skid.
R in poor visibility, e.g. due to fog, heavy rain or
snow.
Distance Pilot DISTRONIC may not detect nar-
row vehicles driving in front, e.g. motorcycles, or
vehicles driving on a different line.
In particular, the detection of obstacles can be
impaired in the following situations:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, e.g. in multi-storey
car parks
If Distance Pilot DISTRONIC no longer detects a vehicle in front, Distance Pilot DISTRONIC may
unexpectedly accelerate to the speed stored.
This speed can:
R be too high for a filter lane or a slip road
R be so high on the right lane that you pass
vehicles driving in the left lane
R be so high in the left lane that you pass vehi-
cles driving in the right lane
If a new driver takes over, advise the new driver
of the speed stored.

R
You switch on the respective turn signal
R Distance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
Stopping If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
i After a short period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake.
i Depending on the specified minimum dis-
tance, your vehicle will come to a standstill at
a sufficient distance behind the vehicle in
front. The specified minimum distance is set
using the control on the cruise control lever.
When Distance Pilot DISTRONIC is activated,
the transmission is shifted automatically to
position Pif:
R the driver's seat belt is not fastened and the
driver's door is open
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function
The electric parking brake is applied automati-
cally if Distance Pilot DISTRONIC is active when
the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a fault occurs, the transmission may also shift
to position Pautomatically.
Setting a speed Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.

The last stored speed increases or decreases
in 10 km/h increments.
i Distance Pilot DISTRONIC is not deactivated
if you depress the accelerator pedal. If you
accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the last speed stored after you have finished over- taking.
Setting the specified minimum distance You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function, you can set the minimum distance that Distance Pilot DISTRONIC maintains to the vehi-
cle in front, dependent on the vehicle speed. You can see this distance in the multifunction dis-
play (Y page 171).
The specified minimum distance can be
changed while Distance Pilot DISTRONIC is
switched on or off.
i Make sure that you maintain the minimum
distance to the vehicle in front as required by
law. Adjust the distance to the vehicle in front
if necessary. 170

AMG vehicles)
Important safety notes G
WARNING
If you use start-off assist, individual wheels
may start to spin and the vehicle may skid. If
ESP ®
is deactivated, there is a greater danger
of skidding and having an accident. Make sure that no persons or obstacles are in the area
around the vehicle. Start-off assist enables optimum acceleration
from a standstill. For this, a suitably high-grip
road surface is required; the tyres and vehicle
must also be in good condition.
Do not activate start-off assist on public roads.
Observe the safety notes on driving safety sys-
tems (Y page 66).
Be sure to read the safety notes and information
on ESP ®
(Y page 69).

Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC shows you
the distance between your vehicle and an obsta- cle visually and audibly.
Parking Assist PARKTRONIC is only an aid. It is
not a substitute for your attention to the imme-
diate surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that there are no persons, animals or
objects in range while manoeuvring and parking.
! When parking, pay particular attention to
objects above or below the sensors, such as flower pots or trailer drawbars. Parking Assist
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of the
vehicle. You could damage the vehicle or the
objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of a lorry or a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
! Fold in the ball coupling if the trailer tow
hitch is not required. Parking Assist
PARKTRONIC measures the minimum detec-
tion range to an obstacle from the bumper,
not the ball coupling.
Parking Assist PARKTRONIC is activated auto-
matically when you: R switch on the ignition
R shift the transmission to position D,Ror Non
vehicles with automatic transmission
R release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 18 km/h. It is reactivated at lower
speeds.
Vehicles with a trailer tow hitch: Parking
Assist PARKTRONIC is deactivated for the rear
area when you establish the electrical connec-
tion between your vehicle and a trailer.
Range of the sensors General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
R below the detection range, e.g. persons, ani-
mals or objects
R above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
