WARNING Risk of accident and inju ry
due toleaving children unat tended in the
ve hicle
If ch ildren are left unat tended in theve hicle,
th ey could, in part icular:
R open doors, thereby endangering other
persons or road users.
R get out and be stru ck byoncoming traf fic.
R operate vehicle equipment and become
trapped, forex ample.
In addition, thech ildren could also set the
ve hicle in motion by,fo rex ample:
R releasing the parking brake.
R changing the transmission position.
R starting theve hicle. #
Never lea vechildren unat tended in the
ve hicle. #
When leaving theve hicle, alw aysta ke
th eke y with you and lock theve hicle. #
Keep theve hicle key out of there ach of

DANG ER Risk of death caused by
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and leads topoisoning. #

Driving and driving saf
ety sy stems Note
s on driving sy stems and your responsi‐
bility Yo
ur vehicle is equipped with driving sy stems
which assist you in driving, parking and manoeu‐
vring theve hicle. The driving sy stems are only
aids. They are not a substitute foryo u paying
attention toyour sur roundings and do not relie ve
yo u of your responsibility per taining toroad traf‐
fi c la w.The driver is alw aysre sponsible for main‐
ta ining a safe dis tance totheve hicle in front, for
ve hicle speed, for braking in good time and for
st ay ing in lane. Alw ays pay attention tothe tra ffic
and inter vene if necessa ry. Be aware of the limi‐
ta tions rega rding the safe use of these sy stems.
Driving sy stems can neither reduce therisk of
accident if youfa ilto adapt your driving style nor
ove rride the la wsof ph ysics. They cannot alw ays
ta ke into account road, weather or traf fic condi‐
tions. In
fo rm ation on vehicle sensors and cameras Some driving and driving saf
ety sy stems use
cameras and radar or ultrasonic sensors tomoni‐

WARNING Risk of accident due to

cle sensors and cameras
If th e area around vehicle sensors or cameras
is co vered, damaged or dirty, cer tain driving
and saf ety sy stems cann otfunction cor rectly.

Keep the area around vehicle sensors or
cameras clear of any obstructions and
clean. #
Have damage tothe bumper, radiator
grille or stone chipping in the area of
th e front and rear wind owsrepaired at a
qu alified specialist workshop. Ke
ep the areas of the cameras and sensors free
of dirt, ice and slush (/ page 229). The sensors
and cameras must not be co vered and the de tec‐
tion ranges around them must be kept free. Do
not attach additional license pla tebrac kets,
ad vertisements, sticke rs,fo ils or foils toprotect
against stone chippings in the de tection range of
th e sensors and cameras. Make sure that there
are no overhanging loads pr otru ding into the
de tection range.
In theeve nt of damage, or following a se vere
impact, ha vethe function of the sensors checked
at a qualified specialist workshop. Ha vedamage
