Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and that fuel consumption and the oil level are normal.
• Before leaving on a trip, fill the fuel tank andmake sure the hybrid battery is fully charged.During the trip, make a habit of refueling reg-ularly.
• Check for fuel, oil, and fluid leakage.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully and replace thosethat are worn. Also, check tire inflation pres-sure.
• The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to drive in countries where it may be difficult toobtain the correct fuel.
• Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Driving economically with the XC90 T8Twin Engine Plug-in Hybrid
Plan your driving in order to utilize the electric motor as much as possible. An energy-conserving driving style lowers current consumption from the hybrid battery and helpsincrease electric driving range.
Charging
• Charge the hybrid battery regularly using the charging cable. Whenever possible, begin adrive with a fully charged battery.
• Check the location of charging points.
• Where possible, choose parking spaces withcharging points.

Fuses The fuses help protect the vehicle's electrical components from overloading or short circuits.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the lists offuses. Doing so could seriously damage oroverload the vehicle's electrical system. Orange wires may only be handled by trained and authorized Volvo service technicians orlicensed electricians. A number of component in the vehicle used high voltage electrical current and can be verydangerous to touch. Do not touch any components that are not clearly described in this owner's information.
If an electrical component fails to function, this may be due to a blown fuse. If the same fuseblows repeatedly, this indicates a problem withthe component, which should be inspected by atrained and qualified Volvo service technician.

Replacing fuses The fuses help protect the vehicle's electrical components from overloading or short circuits.
Fuse replacement1. See the list of fuse boxes for their locations.
2. Pull the fuse straight out and examine it from
the side to see if the curved metal wire in the fuse is intact.
3. If the wire is broken, insert a new fuse of the same color and amperage (written on thefuse).
WARNING
Never use metal objects or fuses with higher amperage than those stated on the followingpages. Doing so could seriously damage oroverload the vehicle's electrical system.
