G
Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle with the key removed.
Never leave children unsupervised in the vehi-
cle. They could release the parking brake. This
could lead to a serious or fatal accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances come into contact
with easily ignitable material such as dry grass
or petrol. Otherwise, the flammable material
may ignite and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied
R on vehicles with manual transmission,
engage first gear or reverse gear
R on vehicles with automatic transmission*,
the transmission must be in position Pand
the key must be removed from the ignition
lock
R on steep uphill or downhill gradients, turn
the front wheels towards the kerb
Parking brake X
To apply: depress parking brake ;firmly.

cluster goes out. Switching off the engine
G
Risk of accident
If the engine is not running, there is no power
assistance for the steering and brakes. Steer-
ing and braking will then require significantly
greater effort.
As a result, you might lose control of the vehi-
cle, cause an accident and injure yourself and
others.
Therefore, do not switch off the engine while
you are driving.

or
X Briefly press the cruise control lever in the
direction of arrow A.

cator lamp ;in the cruise control lever
lights up.
Cruise control is automatically deactivated if:
R you depress the parking brake.
R you drive at less than 30 km/h
R ESP ®
intervenes or you deactivate ESP ®
R you change into neutral in a vehicle with
manual transmission while driving or if the
clutch is depressed for longer than 6 sec-
onds
R on vehicles with manual transmission, you
shift to a higher gear and as a result the
engine speed is too low
R you move the selector lever to Non vehi-
cles with automatic transmission* while
driving
If cruise control is deactivated, you will hear
a warning tone. You see the Cruise con‐
trol off message in the multi-function dis-
play for approximately five seconds.
i The last speed stored is cleared when you
switch off the engine. Distronic Plus*
i Distronic Plus is not available in all coun-
tries.
Distronic Plus regulates the speed and auto-
matically maintains the distance to the vehi-
cle in front. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range 1,2or 3in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
Risk of accident
Distronic Plus is only an aid designed to assist
driving. The driver is fully responsible for the
vehicle's distance from other vehicles, the
vehicle's speed and for braking in good time.
Distronic Plus does not react to:
R pedestrians
R stationary obstacles on the road, e.g. stop-
ped or parked vehicles
R oncoming and crossing traffic
Distronic Plus may not detect narrow vehicles
driving in front, e.g. motorcycles, or vehicles
driving on a different line. Therefore, always
pay attention to traffic conditions even when
Distronic Plus is activated. Otherwise, you
may fail to recognise dangers in time, cause
an accident and injure yourself and others.
If a slower-moving vehicle is detected in front,
Distronic Plus causes your vehicle to brake
and maintain a preset distance to the vehicle
in front. 140

G
Risk of accident
Distronic Plus cannot take account of road
and traffic conditions. If Distronic does not
recognise or no longer recognises the vehicle
in front, do not activate Distronic or, if it is
already active, deactivate it. This is especially
the case:
R before corners
R in filter lanes
R when changing to a lane with faster moving
traffic
R in complex driving situations or where the
lanes are diverted, e.g. at motorway/road-
way construction sites
Otherwise, Distronic Plus maintains the cur-
rent speed or accelerates up to the set speed.
Distronic Plus cannot take account of weather
conditions. Deactivate, or do not activate,
Distronic Plus:
R if the roads are slippery, snow-covered or
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
R if the sensors are dirty or there is poor vis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when Distronic Plus is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
The radar sensor system is automatically
deactivated near radio telescope facilities
(Y page 362).
If you want Distronic Plus to assist you, the
radar sensor system must be activated and
operational.
If no car is driving in front of you, Distronic
Plus works like cruise control in the speed
range between 30 km/h and 200 km/h. If a
vehicle is driving in front of you, Distronic Plus
works in the speed range between 0 km/h
and 200 km/h. Do not use Distronic Plus while driving on
roads with steep gradients. G
Risk of accident
Distronic Plus brakes your vehicle at a maxi-
mum of 4m/s2
depending on its speed. This
corresponds to approximately 40% of your
vehicle's maximum brake force. You must
also apply the brakes yourself if this braking
power is not sufficient.
If Distronic Plus detects a risk of collision with
a vehicle in front, an intermittent warning tone
sounds. In addition, the ·distance warn-
ing lamp in the instrument cluster lights up.
Brake to avoid a collision.

; To deactivate/activate PARKTRONIC
If indicator lamp :lights up, PARKTRONIC is
deactivated. Parking Guidance is also deacti-
vated.
i PARKTRONIC is automatically activated
when you turn the key to position 2in the
ignition lock.
Trailer towing* PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer.
!
Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC meas-
ures the minimum detection range to an
obstacle from the bumper, not the ball cou-
pling. Parking Guidance*
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitable parking space is indicated by the
parking symbol. You receive steering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 157). G
Risk of accident
Parking Guidance is merely an aid and may
recommend parking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited, drive-
ways, unsuitable surfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring. G
Risk of accident
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. These are not
taken into account when the parking proce-
dure is calculated, e.g. overhanging loads, tail
sections or loading ramps of goods vehicles.
In some circumstances, Parking Guidance
might therefore issue steering instructions
too soon. This may lead to a collision. For this
reason, you should avoid using Parking Guid-
ance in such situations. Driving systems

Information and warning display
:
Yellow indicator lamp/red warning lamp
When you turn the key to position 2in the
ignition lock, warning lamps :in the exterior
mirrors light up red.
If Blind Spot Assist is switched on and the
engine is running, indicator lamps :in the
exterior mirrors light up yellow up to a speed
of 30 km/h. At speeds above 30 km/h, the
indicator lamp goes out and Blind Spot Assist
is operational.
If a vehicle is detected within the monitoring
range of Blind Spot Assist at speeds above
30 km/h, warning lamp :on the corre-
sponding side lights up red. This warning is
always issued when a vehicle enters the blind
spot monitoring range from behind or from
the side. When you overtake a vehicle, the
warning only occurs if the difference in speed
is less than 12 km/h.
The yellow indicator lamp goes out after
reverse gear is engaged. In this event, Blind
Spot Assist is no longer active.
The brightness of the indicator/warning
lamps is adjusted automatically according to
the ambient light. G
Risk of accident
Blind Spot Assist is not active at speeds below
30 km/h, and the indicator lamps in the exte-
rior mirrors are yellow. Vehicles in the moni-
toring range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to recognise dangers in time, cause an accident
and injure yourself and others.
Collision warning
If a vehicle is detected in the monitoring range
of Blind Spot Assist and you switch on the turn
signal, a double warning tone sounds. Red
warning lamp :flashes. If the turn signal
remains on, detected vehicles are indicated
by the flashing of red warning lamp :. There
are no further warning tones.
Switching on Blind Spot Assist
X Make sure that the radar sensor system
(Y page 134) and Blind Spot Assist
(Y page 130) are activated in the on-board
computer.
X Turn the key to position 2in the ignition
lock.
Red warning lamps :in the exterior mir-
rors are lit.
X Start the engine.
Warning lamps :in the exterior mirrors
now light up yellow.
Trailer towing*
Blind Spot Assist is deactivated when you
connect the trailer to your vehicle electrically.
The Blind Spot Assist currently
unavailable See Owner's Manual mes-
sage appears in the multi-function display.
Lane Keeping Assist If you select
kmon the on-board computer in
the Speed-/odometer: function
(Y page 131), Lane Keeping Assist is activa-
ted starting at a speed of 60 km/h. If the
miles display unit is selected, the assistance
range begins at between 35 and 40 mph.
Lane Keeping Assist is designed to detect
lane markings on the road and warn you
before you leave your lane unintentionally.
Usually the warning is given when a front
wheel passes over a lane marking. It will warn
you by means of intermittent vibration in the
steering wheel for up to 1.5 seconds. Driving systems
