#Intheevent of damagetothethreads,contact aqualified specialistworkshopimmediately.
#Havethe damaged wheel bolts or dam‐aged hubthreadsreplaced.
#Do not continue driving.
#Observethe information onthechoice oftires (→page 454).
For tires with a specified direction ofrotation, anarrowonthe sidewall ofthe tire indicatesthecorrect direction ofrotation. Observethe direc‐tion ofrotation when installing.
#Slidethe wheeltobe mounted ontothealignment bolt and push it on.
&WARNINGRisk of injuryfrom tighteningwheel bolts and nuts
Ifyou tightenthe wheel bolts or wheel nutswhenthevehicle israised,the jack could tip.
#Only tighten wheel bolts or wheel nutswhenthevehicle is onthe ground.
#Be suretoobservethe instructions andsafety notes on "Changing a wheel"(→page 454).
#For safetyreasons, onlyuse wheel boltswhich havebeen approvedbyMercedes-Benz andforthe wheel inquestion.
