&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
tires (→page 382).
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
when theve hicle is on the ground.
#Fo r saf etyre asons, only use wheel bolts
whic h havebeen appr ovedby Mercedes-

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 transmitte rsare manipulated or

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.

engine and the emission control sy stem.
#Only refuel with lo w-sulfur unleaded
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 instruction label in the
fuel filler flap (
→page 140).
If yo uwa nt maximum engine output: only
re fuel with unleaded premium grade gasoline
with an octane number of at least 91AKI/
95 RON.
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.
* NO
TEPremature wearthro ugh unleaded
re gular gasoline
Unleaded regular gasoline can cause the
engine towe ar more quickly and impair lon‐

If unleaded premium grade gasoline is
una vailable and you ha vetorefuel using
unleaded regular gasoline with 87AKI/
91 RON:
#Only fill th e fuel tank tohalf full with
unleaded regular gasoline and top up as

soon as possible with unleaded pre‐
mium gradegasoline.
#Do not drive at the maximum speed.
#Av oid sudden acceleration and engine
speeds over 3000 rpm.
This may reduce engine output and increase fuel
consum ption. Ne verre fuel using gasoline with a
