Important safety notes
GWARNING
Fuel is highly flammable. If you handle fuel
incorrectly, there is a risk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refuelling.
GWARNING
Fuels are poisonous and hazardous to health.
There is a danger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren.
If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately.GWARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is a risk of
fire and explosion.
Always touch the vehicle body before opening
the fuel filler flap or touching the fuel pump
nozzle. This discharges any electrostatic
charge that may have built up.
GWARNING
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of
pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Do not switch

XBriefly pull the cruise control lever
( Y page 174) towards you ?.XRemove your foot from the accelerator
pedal.
DISTRONIC PLUS is activated. The first
time it is activated, the current speed is
stored. Otherwise, it sets the vehicle cruise
speed to the previously stored value.
Driving with DISTRONIC PLUS
Pulling away and driving
i The vehicle can also pull away when it is
facing an unidentified obstacle or is driving
on a different line from another vehicle. The
vehicle then brakes automatically. There is
a risk of an accident. Be ready to brake at
all times.
If you depress the brake, DISTRONIC PLUS is
deactivated unless your vehicle is stationary.
XIf you want to pull away with DIS-
TRONIC PLUS: remove your foot from the
brake pedal.XBriefly pull the cruise control lever
( Y page 174) 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 vehi-
cle accelerates to the set speed.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control.
If DISTRONIC PLUS detects that the vehicle
in front has slowed down, it brakes your vehi-
cle. In this way, the distance you have selec-
ted is maintained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
The vehicle is only accelerated up to the
speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving
style when you have selected the S or M driv-
ing program ( Y page 155). Acceleration
behind the vehicle in front or to the set speed
is then noticeably more dynamic. If you have
selected the E driving program, the vehicle
accelerates more gently. This setting is rec-
ommended in stop-and-start traffic.
Changing lanes
If you change to the overtaking lane, DIS-
TRONIC PLUS supports you if:
R you are driving faster than 70 km/h
R DISTRONIC PLUS is maintaining the dis-
tance to a vehicle in front.
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect a danger
of collision
If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changing lanes takes too long or if the dis-
tance between your vehicle and the vehicle in
front becomes too small.
i When you change lanes, DISTRONIC
PLUS monitors the left lane for left-hand-
drive vehicles and the right lane for right-
hand-drive vehicles.
StoppingGWARNING
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.
176Driving systemsDriving and parking

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.
For further information on deactivating DIS-
TRONIC PLUS ( Y page 178).
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.
i After a time, the electric parking brake
secures the vehicle and relieves the service
brake.
i 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.
The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
and:
R the seat belt is unfastened 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
R a system fault occurs
R the power supply is not sufficient
If a fault occurs, then the transmission may
also be shifted into position P automatically.

PARKTRONIC
Important safety notes
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
182Driving systemsDriving and parking

Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately.
R pay attention to the PARKTRONIC
( Y page 184) warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be cancelled.
R when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains are fitted.
R make sure that the tyre pressures are
always correct. This has a direct influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces:
R that are parallel or at right-angles to the
direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Detecting parking spaces
Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles.
GWARNING
If objects are located above the detection
range, Active Parking Assist may start to steer
into the parking space too soon. As a result,
you could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop the vehicle and switch Active
Parking Assist off.
For further information on the detection
range ( Y page 183).
Active Parking Assist does not support you
parking in spaces at right angles to the direc-
tion of travel if:
R two parking spaces are located directly
next to one another
R the parking space is directly next to a low
obstacle such as a low kerb stone
R you forward park
Active Parking Assist does not support you
parking in spaces that are parallel or at right
angles to the direction of travel if:
R the parking space is on a kerb stone
R the parking space appears to be blocked,
for example by foliage or grass paving
blocks
R the range of movement is too small
R the parking space is bordered by an obsta-
cle which is not clearly defined such as a
tree or a trailer
Example: detected parking space for a vehicle with
automatic transmission
:Detected parking space on the left;Parking symbol=Detected parking space on the rightDriving systems187Driving and parkingZ

Active Parking Assist is switched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
R that are parallel or at right angles to the
direction of travel
R that are parallel to the direction of travel
and are at least 1.5 m wide
R that are parallel to the direction of travel
and at least 1.0 m longer than your vehicle
R that are at right angles to the direction of
travel and at least 1.0 m wider than your
vehicle
i In the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
When driving at speeds below 30 km/h, you
will see parking symbol ; as a status indi-
cator in the instrument cluster. When a park-
ing space has been detected, an arrow
towards the right or the left also appears.
Active Parking Assist only displays parking
spaces on the front-passenger side as stand-
ard. Parking spaces on the driver's side are
displayed as soon as the turn signal on the
driver's side is activated. When parking on the
driver's side, this must remain switched on
until you acknowledge the use of Active Park-
ing Assist by pressing the a button on the
multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it.ParkingGWARNING
Active Parking Assist merely aids you by inter-
vening actively in the steering. There is a risk
of accident if you do not apply the brakes
yourself.

Parking tips:
R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the kerb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist.
R You can also preselect the forward gear.
The vehicle redirects and does not drive as
far into the parking space. Should a gear be
changed too early, the parking procedure
will be cancelled. A sensible parking posi-
tion can no longer be achieved from this
position.
Exiting a parking space
In order that Active Parking Assist can sup-
port you when you exit the parking space:
R the border of the parking space must be
high enough. A kerb stone is too small, for
example.
R the border of the parking space must not
be too wide, as the position of the vehicle
must not exceed an angle of 45° to the
starting position as it is manoeuvred into
the parking space.
R a manoeuvring distance of at least 1.0 m
must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
XStart the engine.XSwitch on the turn signal in the direction
