R you apply the electric parking brake or if the
vehicle is automatically secured with the elec-
tric parking brake
R ESP ®
intervenes or you deactivate ESP ®
R the transmission is in the P,Ror Nposition
R you pull the cruise control lever towards you
in order to pull away and the front-passenger
door is open
R the vehicle has skidded If Distance Pilot DISTRONIC is automatically
deactivated, you will hear a warning tone. The

Tips for driving with Distance Pilot
DISTRONIC General notes
The following contains descriptions of certain
road and traffic conditions in which you must be particularly attentive. In such situations, brake if
necessary. Distance Pilot DISTRONIC will then
be deactivated.
Cornering, entering and exiting a bend The ability of Distance Pilot DISTRONIC to
detect vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late.
Vehicles which are not driving in the mid-
dle of their lane Distance Pilot DISTRONIC may not detect vehi-
cles which are not driving in the middle of their
lane. The distance to the vehicle in front will be
too short. Driving syste

When the Distance Pilot is deactivated or not
available, Steering Pilot and Stop&Go Pilot are
deactivated automatically. Speed limiter
General notes The limiter brakes automatically so that you do
not exceed the set speed. On long and steep
downhill gradients, especially if the vehicle is
laden, you must select a lower gear in good time.
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 long-term speed restrictions,
e.g. when driving with winter tyres fitted
(Y page 172)
i The speed indicated in the speedometer
may differ slightly from the speed stored.
Important safety notes If you fail to adapt your driving style, the limiter
can neither reduce the risk of an accident nor
override the laws of physics. The limiter cannot take into account road, weather or traffic con-
ditions. The limiter is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in good
time.
If there is a change of drivers, advise the new
driver of the speed stored.

selected.
You can use the cruise control lever to limit the
speed to any speed above 30 km/h while the
engine is running.
Selecting the variable speed limiter
X Check whether LIM indicator lamp ;is on.
If it is on, the variable limiter is already selec-
ted.
If it is not, press the cruise control lever in the
direction of arrow A.

The current speed is stored. You will see the
stored speed for five seconds in the multi-
function display.
Vehicles with cruise control: the stored speed
is permanently displayed in the status indica-
tor.
Vehicles with Distance Pilot DISTRONIC: the
segments from the start of the scale up to the
stored speed light up in the speedometer.
You can use the cruise control lever to limit the
speed to any speed above 30 km/h while the
engine is running.
Storing the current speed or calling up the
last stored speed G
WARNING
If you call up the stored speed and it is lower
than the current speed, the vehicle deceler-
ates. If you do not know the stored speed, the vehicle could decelerate unexpectedly. There
is a risk of an accident.
Pay attention to the road and traffic condi-
tions before calling up the stored speed. If you do not know the stored speed, store the
desired speed again. X
Briefly pull the cruise control lever towards
you =.
Setting a speed
X To adjust the set speed in 10 km/h incre-
ments: briefly press the cruise control lever
up : past 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 the cruise control lever up :for a
higher speed or down ?for a lower speed.
X To adjust the set speed in 1 km/h incre-
ments:
briefly press the 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

Switching the speed limiter to passive
If you depress the accelerator pedal beyond the pressure point (kickdown), the limiter is
switched to passive mode. The following mes-
sage appears in the multifunction display: Lim‐
Lim‐
iter passive iter passive.
You can then exceed the stored speed. The lim-
iter is activated again if you:
R drive slower than the stored speed without
kickdown
R set a new speed or
R call up the last speed stored again

Switching off the speed limiter
Cruise control lever
There are several ways to deactivate the varia-
ble limiter:
X Briefly press the cruise control lever forwards
=.
or
X Briefly press the cruise control lever in the
direction of arrow ;.
LIM indicator lamp :in the cruise control
lever goes out. The variable limiter is deacti-
vated.
Cruise control or Distance Pilot DISTRONIC is

It is not possible to deactivate the variable lim-
iter by braking.
i The last speed stored is cleared when you
switch off the engine.
Permanent limiter If you wish to restrict the maximum speed of the
vehicle for an extended period (e.g. when driving
with winter tyres), the desired maximum speed
can be set with the permanent limiter.
You can use the on-board computer to limit the speed to a value between 160 km/h and
240 km/h(Y page 211).
Shortly before the stored speed is reached, it
appears in the multifunction display. When you
confirm the message with aor%, display
messages no longer appear when switching off
the engine. The speed will only be displayed
again once the engine has been restarted.
The permanent limiter remains active even if the variable limiter is deactivated. The driven speed
will remain below the stored speed even in the
event of kickdown. 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
The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is cancelled and the HOLD
function is deactivated when you depress the
accelerator pedal to pull away.
Important safety notes G
WARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply
R the HOLD function is deactivated by the
accelerator pedal being depressed, e.g. by
a vehicle occupant
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R the battery is disconnected
There is a risk of an accident.
Before leaving the vehicle, always deactivate
the HOLD function and secure the vehicle
from rolling away.
! 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

WARNING
Operating the integrated information systems and communications equipment in the vehicle
while driving will distract you from traffic con-
ditions. You could then lose control of the
vehicle. There is a risk of an accident.
Only operate these devices if road traffic con-
ditions permit. If you are unsure about the
surrounding conditions, pull over to a safe
location and make entries only while the vehi-
cle is stationary.
You must observe the legal requirements for the country in which you are currently driving whenoperating the on-board computer. G
WARNING
If the instrument cluster has failed or mal-
functioned, you may not recognise function
restrictions relevant to safety. The operating
safety of your vehicle may be impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer only shows messages or warnings from certain systems in the multifunc-tion display. You should therefore make sure
your vehicle is operating safely at all times.
If the operating safety of your vehicle is
impaired, park the vehicle safely as soon as pos- sible. Contact a qualified specialist workshop.
