STARTING AND DRIVING
285
Conserving electrical current
Keep the following in mind to help minimize bat- tery drain:
• When the engine is not running, avoid using ignition mode
II. Many electrical systems (the
audio system, the optional navigation system, power windows, etc) will function in ignition modes 0 and I. These modes reduce drain
on the battery.
• Please keep in mind that using systems, accessories, etc., that consume a great dealof current when the engine is not runningcould result in the battery being completelydrained. Driving or having the engine runningfor approximately 15 minutes will help keepthe battery charged.
• The optional 12-volt socket in the cargoarea (p. 145) area provides electrical currenteven with the ignition switched off, whichdrains the battery.
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 thatfuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Have the transmission oil level checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that areworn (p. 302). Check tire pressure (p. 309).
• 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 drivein 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 snow tires (p. 316).

WHEELS AND TIRES
302
Tires – tread wear indicator The tires have wear indicator strips running across or parallel to the tread.
G021829
The letters TWI are printed on the side of the tire.
When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indi-cate that the tire should be replaced. Tires withless than 1/16" (1.6 mm) tread offer very poortraction. When replacing worn tires, it is recommended that the tire be identical in type (radial) and sizeas the one being replaced. Using a tire of thesame make (manufacturer) will prevent alterationof the driving characteristics of the vehicle.

Tires – tire economy
A smooth driving style and correct inflation pres- sure can help prolong the tires' service life.
• Maintain correct tire pressure. The tire infla- tion table, see the tire inflation decal on thedriver's door opening.
• Avoid fast starts, hard braking and tirescreeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very impor-tant.
• Unbalanced wheels impair tire economy anddriving comfort.
• Tires must maintain the same direction ofrotation throughout their lifetime.
• When replacing tires, the tires with the mosttread should be mounted on the rear wheelsto reduce the chance of oversteer duringhard braking.
• Hitting curbs or potholes can damage thetires and/or wheels permanently.
