Two-wayradios
Notes on installing two-wayradios
\nWARNINGRisk of accident duetoimproperworkon two-wayradios
The electromagneticradiation from two-wayradios can interferewiththe on-board elec‐tronics if RF transmittersare manipulated orretrofitted incorrectly.
This could jeopardizethe operating safety ofthevehicle.
You should haveallworkon electricaland electronic components carried outat aqualified specialistworkshop.
\nWARNINGRisk of accident from incor‐rect operation of two-wayradios
Ifyou operate two-wayradios incorrectly inthevehicle,the electromagneticradiationcould interferewiththe on-board electronics,e.g.:
Rifthe two-wayradio is not connectedtoanexterior antenna
Riftheexterior antenna is not correctlymounted or is not of lowreflection
This could jeopardiesthe operating safety ofthevehicle.
Havethe low-reflectionexteriorantenna installed at aqualified special‐istworkshop.
When operating two-wayradios inthevehicle, always connectthemtothelow-reflectionexterior antenna.
NOTEInvalidation ofthe operating per‐mit duetofailuretocomply with theinstructionsfor installation and use
The operating permit may be invalidated ifthe instructionsfor installation and use oftwo-wayradios are not observed.
Only use approved frequency bands.
Observethe maximum permissible out‐put power inthese frequency bands.
Only use approved antenna positions.

RGasoline with additives containing metal
Ifyou haveaccidentallyrefueled withthewrong fuel:
Do not switchonthe ignition.
Consult aqualified specialistworkshop.
Iftheavailable fuel is not sufficiently low in sul‐fur,this can produce unpleasant odors.
Onlyrefuel with fuelthat has at leastthe octanenumber specified inthe instruction label inthefuelfillerflap (page159).
Ifyouwant maximum engine output:onlyrefuel with unleaded premium gradegasolinewith an octane number of at least91AKI/95RON.
As atemporary measure, iftherecommendedfuel is notavailable,you may alsorefuel withunleadedregulargasoline with at least87AKI/91RON. This mayreduce engine output andincrease fuel consumption.
Neverrefuel usinggasoline with aneven lowerRON.

\nWARNINGRisk of an accident duetovapor pocketsforming inthe brake sys‐tem
The brakefluid constantly absorbs moisturefromthe air. This lowersthe boiling point ofthe brakefluid. Ifthe boiling point istoo low,vapor pockets mayforminthe brake systemwhenthe brakes are applied hard.
This causesthe braking effecttobeimpaired.
