662 MAINTAINING YOUR VEHICLE
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights (if equipped) that are lighter and less susceptible to
stone breakage than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPAR Glass Cleaner, or any commercial
household-type glass cleaner. Never use an abrasive type
cleaner. Use caution when cleaning the inside rear win-
dow equipped with electric defrosters or the right rear
quarter window equipped with the radio antenna. Do
not use scrapers or other sharp instrument that may
scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or rag that you are using. Do not spray cleaner
directly on the mirror.
