At speeds of up to approximately 70 km/h, BAS
PLUS can react to:
R stationary objects in the path of your vehicle,
e.g. stopped or parked vehicles
R pedestrians in the path of your vehicle
R obstacles crossing your path, which move in
the detection range of the sensors and are
recognised by them
i If BAS PLUS demands particularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
) are activated simulta-
neously (Y page 51).
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
BAS PLUS is deactivated and the brakes func-
tion as usual again if:
R you release the brake pedal
R there is no longer a risk of collision
R no obstacle is detected in front of your vehicle
R you depress the accelerator pedal
R you activate kickdown COLLISION PREVENTION ASSIST
PLUS
General notes i
Observe the "Important safety notes" sec-
tion (Y page 64).
COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an autono-
mous braking function and Adaptive Brake
Assist.
COLLISION PREVENTION ASSIST PLUS can help
you to minimise the risk of a collision with the
vehicle in front or reduce the effects of such a
collision.
If COLLISION PREVENTION ASSIST PLUS
detects that there is a risk of a collision, you will
be warned visually and acoustically. If you do not react to the visual and audible collision warning,autonomous braking can be initiated in critical
situations. If you apply the brake yourself in a
critical situation, the COLLISION PREVENTION
ASSIST PLUS Adaptive Brake Assist assists you. Important safety notes In particular, the detection of obstacles can be
impaired in the case of:
R dirt on the sensors or obscured sensors
R snow or heavy rain
R interference by other radar sources
R strong radar reflections, for example, in multi-
storey car parks
R a narrow vehicle travelling in front, e.g. a
motorcycle
R a vehicle travelling in front on a different line
R new vehicles or after a service on the COLLI-
SION PREVENTION ASSIST PLUS system
Please observe the information in the section on running-in the vehicle (Y page 145).
Following damage to the front end of the vehicle, have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow speeds where there is no visible damage to thefront of the vehicle.
Activating/deactivating The COLLISION PREVENTION ASSIST PLUS is
automatically active after switching on the igni-
tion.
You can activate or deactivate COLLISION PRE-
VENTION ASSIST PLUS in the on-board com-
puter (Y page 244). When deactivated, the dis-
tance warning function and the autonomous
braking function are also deactivated.
If COLLISION PREVENTION ASSIST PLUS is
deactivated, the æsymbol appears in the
assistance graphics display.
Distance warning function General notes
The distance warning function can help you to
minimise the risk of a collision with the vehicle in
front or reduce the effects of such a collision. If the distance warning function detects that there
is a risk of a collision, you will be warned visually
and acoustically.

Useful information
i This Owner's Manual describes all models,
series and optional equipment for your vehi-
cle that were available at the time of going to
press. National variations are possible. Note
that your vehicle may not be equipped with all
of the functions described. This is also the
case for systems and functions relevant to
safety.
i Read the information on qualified specialist
workshops: (Y page 25). Overview of climate control systems
General notes
Observe the settings recommended on the fol-
lowing pages. The windows could otherwise
mist up.
To prevent the windows from misting up:
R switch off climate control only briefly
R activate air-recirculation mode only briefly
R switch on "Cooling with air dehumidification"
R activate the windscreen demisting function
briefly, if required
Climate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances out of the air.
The "Residual heat" function can only be activa-
ted or deactivated with the ignition switched off (Y page 137).
i Ventilate the vehicle for a brief period during
warm weather, e.g. using the "Convenience
opening" feature (Y page 93).
This will speed up the cooling process and the
desired interior temperature will be reached
more quickly.
i The integrated filter filters out most parti-
cles of dust and soot and completely filters
out pollen. It also reduces gaseous pollutants and odours. A clogged filter reduces the
amount of air supplied to the vehicle interior.
For this reason, you should always observe
the interval for replacing the filter, which is
specified in the Service Booklet. As this
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet. i
Vehicles with AIR-BALANCE package:
in
addition to ionisation, the vehicle has an air
filter with anti-allergenic properties that con-
tribute to improved air filtration.
i Under certain environmental conditions, the
residual heat function may be activated auto-
matically an hour after the key has been
removed in order to dry the automatic climate control. The vehicle is then ventilated for 30
minutes. 126

(BlueTEC vehicles only)
General notes To function properly, BlueTEC exhaust gas after-
treatment must be operated with the reducing
agent AdBlue ®
. Topping up AdBlue ®
is part of
the maintenance work. Under normal operating conditions, a full tank of AdBlue
®
should last
until the next service due date.
When the supply of AdBlue ®
is down to approx-
imately 3.8 l, the Refill AdBlue See Own‐ Refill AdBlue See Own‐

X Switch on the ignition for at least 60 seconds.
X Start the engine.
i You can also have the AdBlue ®
tank refilled
at a qualified specialist workshop.
Before driving your vehicle outside Europe, have
the AdBlue ®
supply checked at a qualified spe-
cialist workshop.
Further information about BlueTEC exhaust gas
aftertreatment and about AdBlue ®
can
be obtained from any Mercedes-Benz Service
Centre.
Important safety notes AdBlue
®
is a water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts of
ammonia vapour may be released.
Ammonia vapours have a pungent odour and are
particularly irritating to the skin, to mucous
membranes and to the eyes. You may experi-
ence a burning sensation in your eyes, nose and throat. You may also experience coughing and
watery eyes.
Do not inhale any ammonia vapours that may be
released. Only fill the AdBlue ®
tank in well-ven-
tilated areas.
Do not swallow AdBlue ®
or let it come into con-
tact with skin, eyes or clothing. Keep AdBlue ®
away from children.
If you or others come into contact with AdBlue ®
,
observe the following:
R immediately rinse AdBlue ®
off your skin with
soap and water.
R if AdBlue ®
comes into contact with your eyes,
immediately rinse them thoroughly with clean water. Seek medical attention immediately.
R if AdBlue ®
is swallowed, immediately rinse
your mouth out thoroughly. Drink plenty of
water. Seek medical attention immediately.
R change immediately out of clothing that has
come into contact with AdBlue ®
.
! Only use AdBlue ®
in accordance with
ISO 22241. Do not mix any additives with AdBlue
®
, and do not dilute AdBlue ®
with
water. This may destroy the BlueTEC exhaust
gas aftertreatment system.
! In order to fill the AdBlue ®
tank, the vehicle
must be parked on a level surface. The
AdBlue ®
tank can only be filled as intended
with the vehicle parked on a level surface.
Fluctuations in capacity will thus be avoided.
Filling a vehicle standing on an uneven sur-
face is not permitted. There is a danger of
overfilling, which can cause damage to Blue-
TEC exhaust gas aftertreatment components.
! Surfaces which have come into contact with
AdBlue ®
while refilling should be rinsed
immediately with water, or remove AdBlue ®
with a moist cloth and cold water. If AdBlue ®
has already crystallised, use a sponge and
cold water to clean the area. AdBlue ®
residue
crystallises after a certain amount of time and soils the affected surfaces.
! AdBlue ®
is not a fuel additive and must not
be added to the fuel tank. If AdBlue ®
is added
to the fuel tank, this can lead to engine dam-
age.
Have the AdBlue ®
tank refilled at a qualified
specialist workshop. However, you can also top
up the AdBlue ®
tank:
R at a filling station with an AdBlue ®
filling pump
R with AdBlue ®
refill bottles
R with an AdBlue ®
refill canister
When the pump nozzle switches off automati-
cally during filling at a filling pump, the AdBlue ®
tank has been completely filled. Do not fill the
AdBlue ®
tank any further. AdBlue ®
may leak
out.
To avoid transporting already opened refill con-
tainers in the vehicle, completely empty refill
bottles or canisters when filling the AdBlue ®
tank, if possible.
