Fuses and fuseboxes All electrical functions and components are protected by a number of fuses in order toprotect the vehicle's electrical system fromdamage by short circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified toreplace a fuse. This could cause significantdamage to the electrical system and possi-bly lead to a fire.
WARNING
Orange wiring may only be handled by qualified personnel.
WARNING
A number of electrical components in Twin Engine Plug-in Hybrid vehicles use high-voltage current and can be extremely dan-gerous if handled incorrectly. Do not touch anything that is not clearly described in the vehicle's Owner's Manual.
If any electrical component or function is not responding, the component may have blown a fuse due to temporary overload. If the same fuse blows repeatedly, there may be a prob-lem with the component. Volvo recommendscontacting an authorized Volvo workshop tohave the component checked.

1. Refer to the fuse diagram to locate the fuse.
2. Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
3. If the wire is broken, replace the fuse with a new fuse of the same color and amper-age.

Volvo's leather upholstery * is treated to pro-
tect its original appearance. Over time, sun- light, grease, dirt, etc. could break down theprotective layer. This could result in scratchesand cracking. Leather upholstery * is a natural product that
changes and acquires a beautiful patina over time. Regular cleaning and treatments arerequired to preserve the qualities and color ofthe leather. Volvo offers a comprehensiveproduct, Volvo Leather Care KitWipes, forcleaning and treating leather upholstery.When used as directed, it helps preserve theleather's protective coating. For optimal results, Volvo recommends clean- ing and applying protective cream one to fourtimes a year (or more often as needed). VolvoLeather Care Kit 951 0251 and Volvo LeatherSoftener 943 7429 are available for purchaseat Volvo retailers.
Cleaning the leather upholstery1. Apply the leather cleaner to a damp sponge and squeeze it until the cleanerfoams. 2. Move the sponge in circular motions to
apply the foam to the stain.
3. Dampen the stain thoroughly with the sponge. Let the sponge absorb the stainand do not rub.
4. Dry the stain using a soft towel and let the leather dry completely.
Protecting the leather upholstery1. Apply a small amount of leather protectorto a cloth and then apply the protector tothe leather using light circular movements.
2. Let it dry for approximately 20 minutes. > Protecting the leather upholsterymakes it better able to withstand sun-light's harmful UV rays.
