WARNING Risk of injury from incorrect
positioning of the jack
If yo u do not position the jack cor rectly at
th e appropriate jacking point of theve hicle,
th e jack could tip with theve hicle raised.
#Only position the jack at the appropri‐
ate jacking point of theve hicle. The
base of the jack must be positioned ver‐
tically under the jacking point of the
ve hicle.

TEVehicle damage from the jack
Ifyo u do not position the jack cor rectly at
th e appropriate jack support point of the
ve hicle, the jack could tip over with theve hi‐
cle raised.
#The jack is designed exclusively for
jacking up theve hicle at the jack sup‐
port points.
#Ta ke the box wrench out of the tire-change
to ol kit and place it on the he xagon nut of
th e jack so that the letters AUF are visible.

&WARNING Risk of accident from losing a
wheel
Oiled, greased or damaged wheel bolt/wheel
nut thre ads or wheel hub/wheel mounting
bolt thre ads can cause the wheel bolts/
wheel nuts tocome loose.
As a result, you could lose a wheel while driv‐
ing.
#Ne ver oil or grease theth re ads.
#In theeve nt of damage totheth re ads,
con tact a qualified specialist workshop
immediatel y.
#Have the damaged wheel bolts or dam‐
aged hub thre ads replaced.
#Do not continue driving.
#Obser vethe information on thech oice of

Fo r tires with a specified direction of rotation, an
ar row onthe side wall of the tire indicates the
cor rect dire ction of rotation. Observ eth e direc‐
tion of rotation when ins talling.
#Slide the wheel tobe mounted onto the cen‐
te ring pin and push it on.

WARNING Risk of injury from tightening
wheel bolts and nuts
If yo u tighten the wheel bolts or wheel nuts
when theve hicle is raised, the jack could tip.
#Only tighten wheel bolts or wheel nuts

WARNING Risk of accident due to
improper workon two-w ayradios
The electro magneticradiation from two-w ay
ra dios can inter fere with the on-board elec‐
tronics if RF transmit ters are manipulated or
re trofitted inco rrectly.
This could jeopardize the operating saf etyof
th eve hicle.
#Yo u should ha veall workon electrical
and electronic components car ried out
at a qualified specialist workshop.
&
WARNING Risk of accident from incor‐
re ct ope ration of two-w ayradios
If yo u operate two-wa yra dios incor rectly in
th eve hicle, the electromagnetic radiation
could inter fere with the on-board electronics,
e.g.:
Rif th e two-w ayradio is not connec tedto
an exterior antenna
Rif th eex terior antenna is not cor rectly
mounted or is not of low reflection
This could jeopardies the operating saf etyof
th eve hicle.
#Ha ve the lo w-reflection exterior
antenna ins talled at a qualified special‐
ist workshop.
#When operating two-w ayradios in the
ve hicle, alw ays connect them tothe
lo w- reflection exterior antenna.

TEInva lidation of the operating per‐
mit due tofailure tocomply wi th the
instructions for ins tallation and use

Even small amounts of the wrong fuel could
re sult in damage tothe fuel sy stem, the
engine and the emission control sy stem.
#Only refuel with lo w-sulfur premium
grade fuel.
This fuel may contain up to10 %ethanol.
Yo ur vehicle is suitable for use with E10 fuel.
Do not refuel using:
RDiesel

RGasoline with additives con taining me tal
If yo u accidenta llyrefuel with the wrong fuel:
#Do not switch the ignition on.
#Consult a qualified specialist workshop.
Ifth eav ailable fuel is not suf ficiently low in sul‐
fur, this can produce unpleasant odors.
Only refuel with fuel, that has at least the octane
number specified in the information table in the
fuel filler flap (

If yo uwa nt maximum engine output: only
re fuel with unleaded premium grade gasoline with an octane number of at least
91AKI/

As a temp orary measure, if there commended
fuel is not available, you may also use unleaded
re gular gasoline with an octane number of at
least 87AKI/91 RON.
