Problems with the seat heating / seat ventilation
ProblemPossible causes/consequences and MSolutions
The seat heating or seat
ventilation has switched
off prematurely or can-
not be switched on.The on-board voltage is too low because too many electrical consum-
ers are switched on.
XSwitch off electrical consumers that you do not need, such as the
rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating or seat
ventilation can be switched back on manually.

Driving tips
General driving tips
Important safety notes
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
GWARNING
If you operate mobile communication equip-
ment when driving, you may be distracted
from the traffic situation. You could also lose
control of the vehicle. There is a risk of an
accident.
Only operate this equipment when the vehicle
is stationary.
Observe the legal requirements for the country
in which you are driving. Some jurisdictions pro-
hibit the driver from using a mobile phone while driving a vehicle.
If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
154Driving tips
Driving and parking

RParking Pilot must not be activated.
Rthe transmission must be in positionh.
Rthe driver's door must be closed when you
shift the transmission from positionjtoh
or your seat belt must be fastened.
Rthe front-passenger door and rear doors must
be closed.
Rthe vehicle must not slide.
Activating
XBriefly pull the cruise control lever towards
you ?or push it up :or down ;.
Distance Pilot DISTRONIC is activated.
XRemove your foot from the accelerator pedal.
The vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
If you do not fully release the accelerator
pedal, the Distance
PilotSuspendedmes-
sage appears on 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 push 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
XTo pull away with Distance Pilot
DISTRONIC:
remove your foot from the brake
pedal.
XBriefly pull the cruise control lever towards
you ?.
or
XAccelerate briefly.
The 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 stored speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ- ent line from another vehicle. The vehicle then
brakes automatically.
If Distance Pilot DISTRONIC does not detect a
vehicle in front, the system operates like cruise
control.
If Distance Pilot DISTRONIC detects that the
vehicle in front has slowed down, it brakes the
vehicle. In this way, the specified minimum dis-
tance you have selected is maintained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed to the set speed.
Selecting the drive program
Distance Pilot DISTRONIC supports a sporty
driving style when you have selected the Sor S+
drive program (
Ypage 144). Acceleration
behind the vehicle in front or to the set speed is
then noticeably more dynamic. If you have
selected the Cor Edriving program, the vehicle
accelerates more gently. This setting is recom-
mended in stop-and-start traffic.
Changing lanes
If you change to the overtaking lane, Distance
Pilot DISTRONIC supports you if:
Ryou are driving faster than 45 mph (70 km/ h)
Ryou switch on theappropriat etur nsignal
RDistanc ePilo tDISTRONI Cdoes no tcurrentl y
detec t adanger of collision
If these condition sare fulfilled ,your vehicl eis
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.
When you change lanes, Distance Pilot
DISTRONIC monitors the left lane (on left-hand-
drive vehicles) or the right lane (on right-hand-
drive vehicles).
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 166).
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.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient 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 shifts automatically to position
j
if:
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.
The electric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated when the vehicle is stationary and:
Ra system malfunction occurs.
Rthe power supply is insufficient.
If a malfunction occurs, the transmission may
also be shifted to position jautomatically.
Setting a speed
XPush 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 push
the cruise control lever up :or down ;to
the pressure point.
Every time the cruise control lever is pressed
up : or down ;the last speed stored is
increased or reduced.
XTo adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly push
the cruise control lever up :or down ;
beyond the pressure point.
Every time the cruise control lever is pressed
up : or down ;, the last speed stored is
increased or reduced.
iIf you accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
last speed stored after you have finished over-
taking.
Setting a 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, depending on vehicle speed. You
can see this distance in the multifunction dis-
play (
Ypage 165).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.
