In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or there is a malfunction in
the system, it may not be possible to apply the
released parking brake.
XIf this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away.
XShift the automatic transmission to position
j.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
there is a malfunction in the system. Contact a
qualified specialist workshop.
The electric parking brake performs a function
test at regular intervals while the engine is
switched off. The sounds that can be heard while
this is occurring are normal.

Important safety notes
GWAR NING
If you switch off the ignition while driving,
safety-relevant functions are only available
wit hlimit ations, or not at all.This could affect,
for example, the power steering and the brake
boosting effect. You willrequire cons iderably
more effort to steer and brake. There isa risk
of an acc ident.
Do not switch off the ignition while driving.
GWARNING
If you operate mob ilecommunication equip-
ment when driving, you may be distracted
from the traff icsituation. You could also lose
control of the veh icle. There isa risk of an
acc iden t.
Only operate th is equipment when the veh icle
is stationary.
Observe the legal requirements for the country
in whic h you are driving. Some jur isdictions pro-
hibit thedriver from using a mob ilephone while
driv ing a veh icle. If
you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traff icsituation permits. Ifyou are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear inmind that at a speed of only 30 mph
(approximately 50 km/h), the vehicle covers a
dist ance of 44 ft (approximately 14 m)per sec-
ond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Emission control
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

pressure point for a higher speed, or down=
for a lower speed.
Every time the cruise control lever is pressed
up or down, the last speed stored is increased
or reduced.
XRemove your foot from the accelerator pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
iIf you do not fully release the accelerator
pedal, the DistancePilotSuspendedmes-
sage appears in the multifunction display. The set distance to a slower-moving vehicle in
front will then not be maintained. You will be
driving at the speed you determine by the
position of the accelerator pedal.
You can also activate Distance Pilot DISTRONIC
when stationary. The lowest speed that can be
set is 20 mph (30 km/ h).
XBriefly pull the cruise control lever towards
you ;or press it up :or down =.
Distance Pilot DISTRONIC is activated.
Activating at the current speed/last
stored speed
GWARNING
If you call up the stored speed and it differs
from the current speed, the vehicle acceler-
ates or decelerates. If you do not know the
stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an acci-
dent.
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.
XBriefly pull the cruise control lever towards
you :.
XRemove your foot from the accelerator pedal.
The first time Distance Pilot DISTRONIC is
activated, it stores the current speed or reg-
ulates the speed of the vehicle to the previ-
ously stored speed.
Driving with Distance Pilot DISTRONIC
Pulling away and driving
XIf you want to pull away with Distance
Pilot DISTRONIC: remove your foot from the
brake pedal.
XBriefly pull cruise control ?lever towards
you.
or
XAccelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to the set speed.
iThe vehicle can also pull away when it is
facing an unidentified obstacle or is driving on
a different line from another vehicle. The vehi-
cle then brakes automatically. There is a risk
of an accident. Be ready to brake at all times.
If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise
control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style when you have selected the Sor S+
drive program. Acceleration behind the vehicle
in front or to the set speed is then noticeably
more dynamic. When you select the Cdrive pro-
gram, the vehicle accelerates more gently. This
setting is recommended in stop-and-start traf-
fic.
Additional information on se
lecting the drive
program (Ypage 111).

Changing lanes
If you change to the overtaking lane, Distance
Pilot DISTRONIC supports you if:
Ryou are driving at a speed greater than
45 mph (70 km/h)
Ryou switch on the appropriate turn signal
RDistance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
iWhen you change lanes, Distance Pilot
DISTRONIC monitors the left lane.
Stopping
GWARNING
If you leave the vehicle when it is only being
braked by Distance Pilot DISTRONIC, it could
roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDistance Pilot DISTRONIC is switched off
using the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle
Rthe electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with.
Rthe battery is disconnected
Rthe vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always deactivate
Distance Pilot DISTRONIC and secure the
vehicle against rolling away.
Further information on deactivating Distance
Pilot DISTRONIC (
Ypage 136).
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
to a stop.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
iAfter a time, the electric parking brake
secures the vehicle and relieves the service
brake.
iDepending 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.
The elect
ric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated when the vehicle is stationary and:
Rthe driver's seat belt is not fastened and the
driver's door is open
Rthe engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function
Ra system malfunction occurs
Rthe power supply is insufficient
If a malfunction occurs, the transmission may
also shift to position jautomatically.
Setting a speed
XPress the cruise control lever up :for a
higher speed or down ;for a lower speed.
XTo adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly press
the cruise control lever up :or down ;to

Distance Pilot DISTRONIC may mistakenly
detect vehicles that are crossing your lane. Acti-
vating Distance Pilot DISTRONIC at, for exam-
ple, a traffic light with crossing traffic, could
cause your vehicle to pull away at the wrong
time.
HOLD
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
