Volvo recommends the use of snow tires on all four wheels for winter driving - see the chapter  "Wheels and  tires."
 To prevent the washer fluid reservoir from  freezing, add  washer solvents containing antifreeze  (see age 188 for the
location of the washer fluid reservoir).  This is important since dirt is often splashed  on the windshield during winter
driving, requiring the frequent use of the washers and  wipers. Volvo Washer Solvent should be  diluted as follows:
Down  to 14° F (-10° C): 1 part washer solvent and  4 parts  water Down  to 5° F (-15° C): 1 part washer solvent and  3
parts  water Down  to 0° F (- 18° C): 1 part washer solvent and  2 parts  water Down  to -18° F (-28° C): 1 part washer
solvent and  1 part water.
 Use Volvo Teflon Lock Spray in the locks.
 NOTE 
Avoid using de -icing sprays as they can cause damage to the locks.
Conserving electrical  current
Keep the following in mind to help minimize battery drain:
 When the engine is not running, avoid turning the ignition key  to position II. Many electrical systems (the audio
system, the optional navigation system, power windows, etc) will function with the ignition key  in position I. This
position reduces drain on the battery.
 Please keep in mind that using systems, accessories, etc that consume a  great deal of current when the engine is not
running could result in the battery being completely  drained.
 The optional 12-volt socket in the cargo area provides  electrical current even with the ignition switched off, which
drains  the battery.
 NOTE 
 If the ignition is switched on, a  warning message will be  displayed in the text window in the instrument panel
when the battery charge is low.
 An energy conserving function designed into the vehicle's electrical system will switch off certain functions or
reduce the load on the battery by, e.g.,  reducing the audio system's volume.
Before a long distance trip
It is always worthwhile to have your vehicle checked at a  Volvo retailer before driving long distances. Your retailer
will also be  able to supply you with bulbs, fuses, spark plugs and  wiper blades for your use in 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 is normal.
 Check for fuel, oil, and  fluid leakage
 Have the transmission oil level  checked1.
 Check condition of drive belts.
 Check state of the battery's charge.
 Examine tires carefully (the spare tire as well), and  replace  those that are worn. Check tire pressures.
 The brakes, front  wheel alignment, and  steering gear should be  checked by your Volvo retailer only.
 Check all lights, including high beams.
 Reflective warning triangles  are legally required in some states/provinces.
 Have a  word with your Volvo retailer if you intend to drive in countries where  it may be  difficult to obtain the
correct fuel.
 Consider your destination. If you will be  driving through an  area where  snow or ice are likely to occur, consider
snow tires.
