&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 362).
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, Mercedes-Benz recom‐
mends that you only use wheel bolts which
ha ve been appr oved for Mercedes-Benz vehi‐
cles, as well as forth e wheel in question.

could inter fere with the on-board electronics,
e.g.:
Rif th e RF transmit ter is not connected to
an exterior antenna
Rif th eex terior antenna is not cor rectly
mounted or is not a lo w-reflection type.
This could jeopardize the operating saf etyof

#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 (
