WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with hot parts of the exhaust system or exhaust
gas flow. There is a risk of fire.
Park the vehicle so that no flammable mate-
rial can come into contact with hot vehicle
components. In particular, do not park on dry grassland or harvested grain fields. G
WARNING
If you leave children unattended in the vehi-
cle, they may be able to set the vehicle in
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
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 key
with you and lock the vehicle. Never leave

The function of the electric parking brake is
dependent on the on-board voltage. If the on-
board voltage is low or if there is a malfunc-
tion in the system, it may not be possible to
apply the released parking brake.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it from
rolling away.
X Shift the automatic transmission to posi-
tion P.
It may not be possible to release an applied
parking brake if the on-board voltage is low or
if there is a malfunction in the system. Con-
tact a qualified specialist workshop. The electric parking brake carries out a func-
tion check at regular intervals when the
engine is switched off. Noises that occur are
normal.

Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked tothe set speed.
X Press the cruise control lever up :for a
higher speed or down ;for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored.
X To adjust the set speed in 1 km/h incre-
ments: briefly press the cruise control
lever up :or down ;to the pressure
point.
The last stored speed increases or decrea- ses in 1 km/h increments.
X To adjust the set speed in 10 km/h
increments: briefly press the cruise con-
trol lever up :or down ;beyond the
pressure point.
The last stored speed increases or decrea- ses in 10 km/h increments.
i Cruise control is not deactivated if you
depress the accelerator pedal. If you accel- erate to overtake, cruise control adjusts
the vehicle's speed to the last speed stored
after you have finished overtaking. Deactivating cruise control There are several ways to deactivate cruise
control:
X Briefly press the cruise control lever for-
wards =.
or X Brake.
or
X Briefly move the cruise control lever in the
direction of arrow ;.
Variable SPEEDTRONIC is selected. LIM
indicator lamp :in the cruise control lever
is lit.
Cruise control is automatically deactivated if:
R you apply the electric parking brake
R you are driving at less than 30 km/h
R ESP ®
intervenes or you deactivate ESP ®
R you shift the transmission to position N
while driving
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 dis-
play for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. SPEEDTRONIC
General notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. Change into
a lower gear in good time on long and steep Driving systems
191Driving and parking Z

Afterwards, the vehicle accelerates back to
the speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorways or high-speed major roads at
speeds above 80 km/h. The driving speed is
adjusted to the speed of the queue of vehicles
in the adjacent lane to the left.
i Prevention of overtaking on the right
applies to countries where traffic drives on
the right. In countries where traffic drives
on the left, overtaking on the left is preven-
ted accordingly.
Stopping G
WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
R there is a malfunction in the system or in
the voltage supply.
R DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
Further information on deactivating
DISTRONIC PLUS (Y page 201).
If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains
stationary and you do not need to depress the
brake.
After a short period, the vehicle is secured by
the electric parking brake, thus relieving the
service brake. 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 DISTRONIC PLUS is activated, the
transmission is shifted automatically to posi-
tion 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 secures the vehicle automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a malfunction in the electric parking brake
occurs, then the transmission may also be
shifted into position Pautomatically.
Setting a speed X
Press the cruise control lever up :for a
higher speed or down ;for a lower speed.
X Keep the cruise control lever pressed until
the desired speed is reached.
X Release the cruise control lever.
The new speed is stored. DISTRONIC PLUS
is activated and adjusts the vehicle's speed to the new speed stored.
X To adjust the set speed in 1 km/h incre-
ments: briefly press the cruise control Driving systems

Tips for driving with DISTRONIC PLUS General notes
Pay particular attention in the following traffic
situations:
R Cornering, entering and exiting a bend
R Vehicles which are not driving in the middle
of their lane
R Other vehicles changing lane
R Narrow vehicles
R Obstructions and stationary vehicles
R Crossing vehicles
In such situations, brake if necessary.
DISTRONIC PLUS is then deactivated. Cornering, entering and exiting a bend The ability of DISTRONIC PLUS to detect vehi-
cles when cornering is limited. Your vehicle
may brake unexpectedly or late.
Vehicles which are not driving in the mid- dle of their lane DISTRONIC PLUS may not detect vehicles
which are not driving in the middle of their
lane. The distance to the vehicle in front will
be too short.
