parking 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
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.
X If this is the case, only park the vehicle on
level ground and secure it to prevent it rolling
away.
X Shift the automatic transmission to position
005D.
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.
i The electric parking brake performs a func-
tion test at regular intervals while the engine
is switched off. The sounds that can be heard while this is occurring are normal. Parking

oil level must be sufficiently high to ensure a
correct oil supply in the vehicle.
X DEF tank (BlueTEC vehicles): check the
level and add if necessary (Y page 153).
X Tire-changing tool kit: check that the jack is
working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
X Wheels and tires: check the tread depth and
pressure of the tires.
X Check for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tires.
X Replace any missing valve caps.
X Replace dented or damaged wheels.
X Rims: dented or bent rims can result in a loss
of tire pressure and damage the tire bead. 166
Driving tipsDriving and parking

Driving with Active Distance Assist
DISTRONIC Pulling away and driving
X If you want to pull away with Active Dis-
tance Assist DISTRONIC: remove your foot
from the brake pedal.
X Briefly pull the cruise control lever towards
you 0085.
or
X Accelerate 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.
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 there is no vehicle in front, Active Distance
Assist DISTRONIC operates in the same way as cruise control.
If Active Distance Assist DISTRONIC detects a
slower-moving vehicle in front, it brakes your
vehicle. In this way, the distance you have selec-
ted is maintained.
If Active Distance Assist 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 programActive Distance Assist DISTRONIC supports a
sporty driving style if you have selected the
Sport orSport Plus drive program
(Y page 146). Acceleration behind the vehicle in
front or to the set speed is then noticeably more
dynamic. If you have selected the Comfortdrive
program, the vehicle accelerates more gently.
This setting is recommended in stop-and-start
traffic.
Changing lanes If you change to the overtaking lane, Active Dis-
tance Assist DISTRONIC helps you if:
R you are driving faster than 45 mph (70 km/h)
R you switch on the appropriate turn signal
R Active Distance Assist 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.
i When you change lanes, Active Distance
Assist DISTRONIC monitors the right lane (in
left-side traffic) or the left lane (in right-side
traffic).
Stopping G
WARNING
If you leave the driver's seat when the vehicle is only being braked by Active Distance Assist
DISTRONIC, it could roll away:
R if there is a malfunction in the system or in
the voltage supply
R if Active Distance Assist DISTRONIC is
deactivated using the cruise control lever,
for example by a vehicle occupant or from
outside the vehicle
R if the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R if the battery is disconnected
R if the vehicle is accelerated, e.g. by a vehi-
cle occupant
There is a risk of an accident.
Always deactivate Active Distance Assist
DISTRONIC and secure the vehicle against
rolling away before you leave it.
If Active Distance Assist 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.
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. 174
Driving systemsDriving and pa
rking

When Active Distance Assist DISTRONIC is acti-
vated and the vehicle is at a standstill, the trans-
mission will be shifted automatically to position
005D if:
R the driver's door is open and the driver's seat
belt is unfastened.
R the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
When Active Distance Assist DISTRONIC is acti-
vated and the vehicle is at a standstill, the elec-
tric parking brake will secure the vehicle auto-
matically if:
R a system malfunction occurs
R the power supply is not sufficient
On steep uphill or downhill inclines or if there is a malfunction, the transmission may also be
automatically shifted into position 005D.
Setting a speed Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set.
X Press the cruise control lever up 0043for a
higher speed or down 0083for a lower speed
X To adjust the set speed in 1 mph incre-
ments (1 km/h increments):
briefly press
the cruise control lever up 0043or down 0044to
the pressure point.
Every time the cruise control lever is pressed
up 0043 or down 0044the last speed stored is
increased or reduced.
X To adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly press
the cruise control lever up 0043or down 0044
beyond the pressure point.
Every time the cruise control lever is pressed
up 0043 or down 0044, the last speed stored is
increased or reduced.
i If you accelerate to overtake, Active Dis-
tance Assist DISTRONIC adjusts the vehicle's
speed to the last speed stored after you have
finished overtaking. Setting a specified minimum distance You can set the specified minimum distance for
Active Distance Assist DISTRONIC by varying
the time span between one and two seconds.
This determines the distance that Active Dis-
tance Assist DISTRONIC is to maintain from the
vehicle in front, depending on the road speed.
You can see this distance in the multifunction
display (Y page 176).
X To increase: turn control0044in direction 0087.
Active Distance Assist DISTRONIC then main-
tains a greater distance between your vehicle and the vehicle in front.
X To decrease: turn control0044in direction 0043.
Active Distance Assist DISTRONIC then main-
tains a shorter distance between your vehicle
and the vehicle in front.
i Make sure that you maintain a sufficiently
safe distance from the vehicle in front. Adjust
the distance to the vehicle in front if neces-
sary.

Important safety notes
G
WARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle under "Technical
data" (Y page 394). G
WARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
Please observe the manufacturer's operating
instructions for the trailer coupling if a detach-
able trailer coupling is used.
Couple and uncouple the trailer carefully. If you do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
Make sure that the following values are not
exceeded:
R the permissible trailer drawbar noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
The applicable permissible values, which must
not be exceeded, can be found:
R in the vehicle documents
R on the identification plates for the trailer tow
hitch and the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance 220
Towing a trailerDriving and parking

R
Maintain a greater distance from the vehicle
in front than when driving without a trailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine and, conse-
quently, the vehicle's gradient-climbing capa- bility, decreases with increasing altitude. Installing the ball coupling
