#Do notwarmupthe engine whilethevehicle isstationary.Pullawayimmedi‐ately.
#Avoid high engine speeds and driving atfullthrottle untilthe engine hasreachedits operatingtemperature.
*NOTEDamagetothe catalytic converterduetonon-combusted fuel
The engine is notrunning smoothly and ismisfiring.
Non-combusted fuel mayget intothe cata‐lytic converter.
#Only depressthe accelerator pedalslightly.
#Havethe causerectified immediately ataqualified specialistworkshop.
Limited braking effect on salt-treatedroads:
RDuetosalt build-up onthe brake discs andbrakepads,the braking distance can increaseconsiderably orresult in braking only on oneside
RMaintain a much greater safe distancetothevehicle in front
Toprevent salt build-up:
RBrake occasionally while paying attentiontothe traffic conditions
RCarefully depressthe brake pedal atthe endofthe journey and whenstartingthe nextjourney
