Side windows
Important safety notes
GWARNING
While opening the side windows, body parts
could become trapped between the side win-
dow and the door frame as the side window
moves. There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or
pull the switch to close the side window again.
GWARNING
While closing the side windows, body parts in
the closing area could become trapped. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody
becomes trapped, release the switch or press
the switch to open the side window again.
GWARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
Activate the override feature for the rear side
windows. When leaving the vehicle, always
take the SmartKey with you and lock the vehi-
cle. Never leave children unsupervised in the
vehicle.
Side window reversing feature
The side windows are equipped with an auto-
matic reversing feature. If a solid object
blocks or restricts a side window during the
closing process, the side window opens again
automatically. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing a side window.
GWARNING
The reversing feature does not react:
Rto soft, light and thin objects, e.g. small fin-
gers
Rover the last 1/6 in(4 mm) of the closing
movement
Rduring resetting
Rwhen closing the side window again man-
ually immediately after automatic reversing
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.

Important notes on topping up
DEFisa water-soluble fluid for the exhaust
gas aftertreatment of diesel engines. Itis:
Rnot pois onous
Rcolorless and odorless
Rnot flammable
When you open the DEF container, small
amounts of ammonia vapor may be released. Ammon iavapors have a pungent odor and are
particularly irr itating to the skin, to mucous
membranes and to the eyes. You may expe-
rience a burning sensation in your eyes, nose and throat. Coughing and watering of the
eyes are possible.
Do not inhale ammonia vapors. Fill the DEF
tank only in well- ventilated areas.
DEF must not come into contact with your
skin, eyes or clothing and must not beswal-
lowed. Keep DEF away from children.
If you or other persons come into contact with
DEF, observe the fol lowing:
RRinse DEF from your skin immediatelywith
soap and water.
RIf DEF comes into contact with your eyes,
immediately rinse them thoroughly with
clean water. Seek medical assistance with-
out delay.
RIf DEF has been swallowed,rinse your
mouth out immediately. Drink plenty of
water. Seek medical assistance without
delay.
RChange out of clothing contaminated with
DEF immediately.
!Only use DEF in accordance with
IS O 22241. Do not mix any additives with
DEF, and donot dilute DEF with water. This
may destroy th e B
lueTEC exhaust gas after-
treatment system.
!Rins e surfaces that have come into con-
tact with DEF immediately with water or
remove DEF using a damp cloth and co ld
water. Ifthe DEF has already crystallized,
use a sponge and co ldwater to clean it. DEF residues crystallize after time and contam-
inate the affected surfaces.
!DEF
isnot a fuel additive and must not be
added to the fuel tank. IfDEF isadded to
the fuel tank, th iscan lead to engine dam-
age.
!Only screw on the DEF ref illbottle hand-
tight. Itcould otherwise bedamaged.

Parking
Important safety notes
GWARNING
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-
rials come into contact with parts of the vehi-
cle which are hot. Take particular care not to
park on dry grassland or harvested grain
fields.
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
